Abstract
OBJECTIVE The high frequency of reinterventions after fenestrated endovascular aortic repair (FEVAR) with physician-modified endografts (PMEGs) has been well-studied. However, the impact of prior EVAR on reinterventions and sac behavior following these procedures remains unknown. We analyzed 3-year rates of reinterventions and sac dynamics following PMEG for index aneurysm repair compared with PMEG for prior EVAR with loss of proximal seal. METHODS We performed a retrospective analysis of 122 consecutive FEVARs with PMEGs at a tertiary care center submitted to the United States Food and Drug Administration in support of an investigational device exemption trial. We excluded patients with aortic dissection (n = 5), type I to III thoracoabdominal aneurysms (n = 13), non-elective procedures (n = 4), and prior aortic surgery other than EVAR (n = 8), for a final cohort of 92 patients. Patients were divided into those who underwent PMEG for index aneurysm repair (primary FEVAR) and those who underwent PMEG for rescue of prior EVAR with loss of proximal seal (secondary FEVAR). The primary outcomes were freedom from reintervention and sac dynamics (regression as ≥5 mm decrease, expansion as ≥5 mm increase, and stability as <5 mm increase or decrease) at 3 years. Secondary outcomes were perioperative mortality and 3-year survival. RESULTS Of the 92 patients included, 56 (61%) underwent primary FEVAR and 36 (39%) underwent secondary FEVAR. Secondary FEVAR patients were older (78 years [interquartile range (IQR), 74.5-83.5 years] vs 73 years [IQR, 69-78.5 years]; P < .001), more frequently male (86% vs 68%; P = .048), and had larger aneurysms (72.5 mm [IQR, 65.5-81 mm] vs 59 mm [IQR, 55-65 mm]; P < .001). Perioperative mortality was 1.8% for primary FEVAR and 2.7% for secondary FEVAR (P = .75). At 3 years, overall survival was 84% for primary FEVAR and 71% for secondary FEVAR (P = .086). Freedom-from reintervention was significantly higher for primary FEVAR than secondary FEVAR, specifically 82% vs 38% at 3 years (P < .001). Primary FEVAR also had more desirable sac dynamics relative to secondary FEVAR at 3 years (primary: 54% stable, 46% regressed, 0% expanded vs secondary: 33% stable, 28% regressed, and 39% expanded; P = .038). CONCLUSIONS FEVAR for primary aortic repair and FEVAR for rescue of prior EVAR with loss of proximal seal are two distinct entities. Following primary FEVAR, less than a quarter of patients have undergone reintervention at 3 years, and sac expansion was not seen in our cohort. Comparatively, 3 years after secondary FEVAR, over one-half of patients have undergone reintervention and over one-third have had ongoing sac expansion. Vigilant surveillance and a low threshold for further interventions are crucial following secondary FEVAR.

Abstract
OBJECTIVES Type I and III endoleaks following endovascular aneurysm repair (EVAR) can lead to catastrophic events that require major re-interventions. We reviewed our experience with aortic endograft re-interventions for type I and III endoleaks and other serious failures among different devices. METHODS We retrospectively reviewed patients with a prior EVAR who underwent open conversion (OC) or major endovascular intervention (MEI) (re-lining, cuff/limb extension, parallel graft) for type I/III endoleaks at our institution from 2002 to 2019. Baseline characteristics, procedural details, re-interventions, and outcomes were collected. RESULTS A total of 229 patients (194 men) underwent re-interventions for type I and III endoleaks after EVAR (90 OC, 139 MEI) for devices implanted between 1997 and 2019. Average age at re-intervention was 78±8.5 years. A total of 135 (59%) were implanted at our institution, whereas 93 (41%) were referred. Median time to re-intervention was 4 years with 25% to 75% interquartile range (IQR) of 2.2-6.6 years. There was no significant difference in baseline demographics or type of re-interventions (OC/MEI) between device types. 42/229 (18%) presented with ruptured aneurysms, 20/229 (9%) were symptomatic, whereas the rest presented with asymptomatic radiographic findings. Type 1A endoleak was present in 146/229 (63.8%-72 with proximal migration), type IB in 46/229 (20.1%), type IIIA in 37/229 (16.6%), type IIIB in 15/229 (6.5%), and persistent aneurysm sac growth with no radiographic evidence of an endoleak in 6/229 (2.6%). Devices included most commercial products: AFX, Excluder, AneuRx, Ancure, Endurant, and Zenith. A smaller number of investigational devices accounted for the rest. Type 1A endoleak was the most common indication for re-intervention among all devices except for AFX and ancure devices, proximal migration was a frequent presentation with AneuRx. AFX devices more frequently presented with a type III and ancure devices more frequently presented with a type IB endoleak. CONCLUSIONS Serious failure modes after EVAR differ between endografts and occur throughout the follow-up period. This is important to guide targeted interrogation of surveillance studies and follow-up schedules, even for discontinued devices, as well as comparisons between various series and estimation of EVAR failure rates. CLINICAL IMPACT Surveillance after EVAR is critical for long term success of the repair, understanding of the differential modes of failure of every graft available is important in the longitudinal evaluation of these endografts. Equally important is the understanding of the modes of failure of legacy endografts that are no longer on the market but still being followed, in order to be able to tailor a surveillance regiemn and the evntual repair if needed.

Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) has become the standard procedure for treating infrarenal abdominal aortic aneurysms (AAA). Various associated complications can lead to open conversion (OC). Thorough follow-up after the procedure is mandatory for the early detection of complications. Persisting perfusion of the aneurysm, a so-called endoleak (EL), paired with structural instability because of aortic wall atrophy and impaired cell functionality induced by EVAR, results in a high risk for aortic rupture. PURPOSE The goal of this study was to detect the risk factors for elective and urgent OC as a result of EVAR-induced pathophysiological changes inside the aortic wall. RESEARCH DESIGN Retrospective data analysis was performed on all open aortic repairs from January 2016 to December 2020. DATA COLLECTION AND ANALYSIS Fifty patients were identified as treated by OC for failure of an infrarenal EVAR. The patients were divided into two subgroups, here depending on the urgency of surgery. Statistical analysis of patient characteristics and outcomes was performed. RESULTS The most common indications for OC were various types of EL (74%), resulting in an aortic rupture in 15 patients. Patients with insufficient or absent follow-up were treated more frequently in an emergency setting (16% vs. 63%). The mortality rate was higher in cases of emergency OC (3% vs. 26%). CONCLUSIONS Particularly in cases of insufficient or absent follow-up, complications such as EL pose an enormous risk for fatal aortic rupture.

Systematic review and meta-analysis of outcomes after semi-conversion with graft preservation for failed endovascular aneurysm repair. J Vasc Surg 2024; 79:973-981.e4. [PMID: 37619915 DOI: 10.1016/j.jvs.2023.08.113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 07/24/2023] [Accepted: 08/15/2023] [Indexed: 08/26/2023]
Abstract
OBJECTIVE The aim of this study was to evaluate the outcomes after semi-conversion (open conversion with graft preservation) after failed endovascular aneurysm repair (EVAR). The primary outcomes were 30-day mortality and semi-conversion failure. Secondary outcomes were 30-day major systemic complications, endoleak recurrence, reinterventions, and overall survival. METHODS The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol was prospectively registered on PROSPERO (CRD42023421153). All studies reporting the outcomes of semi-conversions for failed EVAR were eligible for inclusion. Quality assessment was performed using the Methodological Index for Non-Randomized Studies (MINORS) tool. A random effects meta-regression of proportions was conducted using the double arcsine-Tukey transformation, given the frequent zero event rate in the primary outcome. Heterogeneity was assessed with the I2 statistic. RESULTS Eight studies were included in the review after full text screening. A total of 196 patients underwent semi-conversion at a mean time from EVAR of 47.4 months, 68.9% in an elective setting. Mean age at conversion was 78.1 years, and the main indication was isolated endoleak type II (70.1% of cases). Aortic clamping was not necessary in 92.3% of semi-conversions; the aortic sac was opened in 96.1% of cases; in 93.3% of cases, ligation/suture of one or more culprit arteries were performed; and aortic neck banding was executed in 29.2%. At 30 days from surgery, the pooled mortality and the major systemic complications rates were 5.3% (I2 = 24.9%) and 13.4% (I2 = 54.3%), respectively. At follow-up, endoleak recurred after 12.6% semi-conversions (I2 = 83.2%), and the rate of reinterventions was 7% (I2 = 50.1%); the semi-conversion failure rate was 5.5% (I2 = 54.1%), and the overall survival was 84.6% (I2 = 33.3%). CONCLUSIONS Semi-conversions have acceptable 30-day mortality rates, but the early and mid-term risks of complications, reinterventions, ruptures, and infections are not negligible. This procedure might be an alternative to complete or partial graft explant in patients whom aortic cross-clamping is not ideal.

Abstract
OBJECTIVE To evaluate the early and mid-term outcomes of open repair in patients with thoracoabdominal aortic aneurysm (TAAA) after thoracic endovascular aortic repair (TEVAR). METHODS This was a retrospective single center study. Data were retrospectively collected and analyzed for consecutive patients undergoing open TAAA repair (TAAAR) after TEVAR from November 2016 to June 2021. Indications for TAAAR included aneurysm progression due to endoleak, persisted false lumen perfusion, proximal/distal disease progression, and aorta rupture. The risk factor of operative mortality was analyzed by multivariable logistic regression model and the survival was evaluated by Kaplan-Meier. RESULTS Sixty-three patients who met the inclusion criteria for the study were identified. The mean age at TAAAR was 41 ± 12 years and 43 (68.3%) were male. Marfan syndrome (MFS) was presented in 39 patients (61.9%). 60 (95.2%) patients presented with post-dissection aneurysm and 3 (4.8%) patients with degenerative aneurysm. The extent of TAAA was Crawford I in 9 (14.3%), II in 22 (34.9%), III in 23 (36.5%), and IV in 9 (14.3%). Emergent TAAAR was done in 10 (15.9%) patients, and deep hypothermic circulatory arrest was used in 22 (34.6%). Endograft was explanted in 31 (49.2%). Operative mortality was 11 (17.5%). Stroke, paraplegia, and acute kidney failure occurred in 5 (7.9%), 7 (11.1%), and 6 (9.5%) patients, respectively. Pulmonary complications occurred in 19 (30.2%) patients. The estimated survival was 74.8 ± 4.9% at 5 years. Late reoperations were performed in 2 patients at 2.5 years and 1.3 years, respectively. CONCLUSIONS In this series of TAAA after TEVAR, TAAAR was related with a high risk of operative mortality and morbidity and the midterm outcomes represented a durable treatment and were respectable.

Abstract
PURPOSE Outcomes of late open conversion with graft replacement for enlargement after endovascular aortic repair remain unclear. Here, we report the outcomes of graft replacement after endovascular aortic repair. MATERIALS AND METHODS Fourteen patients who underwent graft replacement after endovascular aneurysm repair between November 2016 and October 2022 were included. Graft replacement was indicated in cases of rupture and enlargement of the aneurysm sac and when reintervention with endovascular therapy could not be performed. RESULTS The mean age at graft replacement was 80 ± 7 years. The follow-up period from endovascular aortic repair to graft replacement was 73 ± 41 months. The endoleaks that caused enlargement of the aneurysm sac were type I in 8 patients and type II in 6 patients. Ruptures were observed in 5 patients. One patient had paraplegia as a postoperative complication, and 2 patients died within 30 days. Morbidity and mortality were observed in cases of rupture, and no morbidity or mortality was observed in any elective surgery cases. CONCLUSION Late open conversion with graft replacement after endovascular aortic repair is a feasible elective surgery. However, morbidity and mortality have been observed in cases of rupture. CLINICAL IMPACT In elective surgery, postoperative outcomes are good for late open conversion with graft replacement after endovascular aortic repair. On the other hand, morbidity and mortality were observed in case of rupture. Therefore, it is important to perform elective surgical reintervention at the appropriate time.

Reducing aneurysm sac growth and secondary interventions following endovascular abdominal aortic aneurysm repair by preemptive coil embolization of the inferior mesenteric artery and lumbar arteries. J Vasc Surg 2024; 79:532-539. [PMID: 38008267 DOI: 10.1016/j.jvs.2023.11.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/15/2023] [Accepted: 11/18/2023] [Indexed: 11/28/2023]
Abstract
OBJECTIVE Type II endoleak (EL-2) is the most common complication following endovascular aneurysm repair (EVAR), leading to continued sac growth and potential rupture. In this study, we examined the association between patency of the inferior mesenteric artery (IMA) and lumbar arteries (LAs) with respect to sac growth. The effect of preemptive embolization of the IMA and/or LAs on the need for secondary interventions for sac growth post-EVAR was also evaluated. METHODS A retrospective cohort study was performed on consecutive patients who underwent EVAR for non-ruptured, infrarenal abdominal aortic aneurysms (AAAs) from January 2012 to December 2020. A select group of patients underwent preemptive embolization of the IMA and/or LA. Patients with any types I, III, or IV endoleaks were excluded. Patency of the IMA and LA on preoperative computed tomography angiogram (CTA) was evaluated on TeraRecon workstation. All secondary interventions to treat EL-2 were recorded. Sac growth was defined as centerline axial diameter increase of ≥5 mm on follow-up CTA. RESULTS A total of 300 patients (mean age, 74 ± 8.5 years; 83.7% male) underwent EVAR. Ninety-nine patients had preemptive embolization of the IMA and/or LA. Mean follow-up of the cohort was 59.3 ± 30.5 months. Thirty-six patients (12%) demonstrated sac growth on follow-up; 12 of these (33.3%) had preemptive embolization. The median time until detection of sac growth was 28.8 months (interquartile range, 15.2-46.5 months), with a mean growth of 10.1 ± 6.4 mm. Sac growth was significantly associated with presence of EL-2: 27 of 36 (75%) with EL-2 vs 9 of 36 (25%) without EL-2 (P < .001). Patients with sac growth had a higher mean total number (2.6 ± 1.5) of patent lower LAs (L3, L4) compared with those without (2.0 ± 1.4; P = .03). Patency of L1, L2, and L3 LAs were not associated with sac growth. However, patency of at least one L4 LA was significantly associated with sac growth (14.8% vs 7.7%; P = .04). The highest incidence of sac growth (17.6%) was seen when both IMA and L4 LA were patent; significantly different from the lowest incidence (5.3%) when both were occluded preoperatively (P = .018). Preemptive coiling of the IMA and/or LA significantly reduced the need for post-EVAR secondary intervention for sac growth. Freedom from post-EVAR secondary intervention was achieved in 92 of 99 (92.9%) pre-EVAR coiled patients vs 163 of 201 (81.5%) patients who did not undergo pre-EVAR coiling (P = .009). CONCLUSIONS Preemptive coil embolization of the IMA and LAs, especially L4 LA, reduces the need for secondary interventions for sac growth, potentially improving the long-term durability of EVAR.

Systematic Review and Meta-Analysis of Elective Open Conversion versus Fenestrated and Branched Endovascular Repair for Previous Non-Infected Failed Endovascular Aneurysm Repair. Eur J Vasc Endovasc Surg 2024; 67:393-405. [PMID: 37748552 DOI: 10.1016/j.ejvs.2023.09.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 09/11/2023] [Accepted: 09/19/2023] [Indexed: 09/27/2023]
Abstract
OBJECTIVE To evaluate outcomes of patients electively undergoing fenestrated and branched endovascular repair (F/B-EVAR) or open conversion for failed previous non-infected endovascular aneurysm repair (EVAR). DATA SOURCES Embase, MEDLINE, Cochrane Library. REVIEW METHOD The protocol was prospectively registered on PROSPERO (CRD42023404091). The review followed the PRISMA guidelines; certainty was assessed through the GRADE and quality through MINORS tools. Outcomes data were pooled separately for F/B-EVAR and open conversion. A random effects meta-analysis of proportions was conducted; heterogeneity was assessed with the I2 statistic. RESULTS Thirty eight studies were included, for a total of 1 645 patients of whom 1 001 (60.9%) underwent an open conversion and 644 (39.1%) a F/B-EVAR. The quality of evidence was generally limited. GRADE certainty was judged low for 30 day death (in both groups) and F/B-EVAR technical success, and very low for the other outcomes. Pooled 30 day death was 2.3% (I2 33%) in the open conversion group and 2.4% (I2 0%) in the F/B-EVAR conversion group (p = .36). Technical success for F/B-EVAR was 94.1% (I2 23%). The pooled 30 day major systemic complications rate was higher in the open conversion (21.3%; I2 74%) than in the F/B-EVAR (15.7%; I2 78%) group (p = .52). At 18 months follow up, the pooled re-intervention rate was 4.5% (I2 58%) in the open conversion and 26% (I2 0%) in the F/B-EVAR group (p < .001), and overall survival was 92.5% (I2 59%) and 81.6% (I2 68%), respectively (p = .005). CONCLUSION In the elective setting, and excluding infections, the early results of both open conversion and F/B-EVAR after failed EVAR appear satisfactory. Although open conversion presented with higher complication rates in the first 30 days after surgery, at follow up it seemed to be associated with fewer re-interventions and better survival compared with F/B-EVAR.

Comparative outcomes of physician-modified fenestrated/branched endovascular aortic aneurysm repair in the setting of prior failed endovascular aneurysm repair. J Vasc Surg 2023; 78:1153-1161. [PMID: 37451371 DOI: 10.1016/j.jvs.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 06/29/2023] [Accepted: 07/04/2023] [Indexed: 07/18/2023]
Abstract
OBJECTIVE Endovascular treatment of aortic aneurysms involving renal-mesenteric arteries, especially in the setting of prior failed endovascular aneurysm repair (EVAR) typically requires fenestrated/branched endovascular aneurysm repair (F/BEVAR) with a custom-made device (CMD). CMDs are limited to select centers, and physician-modified endografts are an alternative treatment platform. Currently, there is no data on the outcomes of physician-modified F/BEVAR (PM-F/BEVAR) in the setting of failed prior EVAR. The purpose of this study was to evaluate the use of PM-F/BEVAR in patients with prior failed EVAR. METHODS A prospective database of consecutive patients treated at a single center with PM-F/BEVAR between March 2021 and November 2022 was retrospectively reviewed. The cohort was stratified by presence of a failed EVAR (type Ia endoleak or aneurysm development proximal to a prior EVAR) prior to PM-F/BEVAR. Demographics, operative details, and postoperative complications were compared between the groups using univariate analysis. One-year survival and freedom from reintervention were compared using the Kaplan-Meier method. RESULTS A total of 103 patients underwent PM-F/BEVAR during the study period; 27 (26%) were in the setting of prior EVAR. Patients with prior failed EVAR had similar age (75.2 ± 7.7 vs 71.5 ± 8.8 years; P = .058), male gender (n = 24 ; 89% vs n = 57 ; 75%; P = .130), and comorbid conditions except higher incidence of moderate-to-severe chronic obstructive pulmonary disease (n = 7 ; 26% vs n = 7 ; 9%; P = .047). Overall, aneurysm diameter was 65.5 ± 13.9 mm with aneurysms categorized as juxta-/pararenal in 43% and thoracoabdominal in 57%, with no differences between the groups. Twelve patients (14%) presented with symptomatic/ruptured aneurysms. The average number of target arteries incorporated per patient was 3.8. Four different aortic devices were modified with a greater proportion of Terumo TREO devices used in the failed EVAR group (P = .03). There was no difference in procedure time, radiation dose, or iodinated contrast use between groups. Overall technical success was 99%. Rates of 30-day mortality (n = 0 ; 0% vs n = 3 ; 4%; P = .565) and major adverse events (n = 6 ; 22% vs n = 16 ; 21%; P = 1.0) were similar between groups. For the overall cohort, rates of type 1 or 3 endoleak, branch vessel stenosis/occlusion, and reintervention were 2%, 1%, and 8%, respectively, with no difference between groups. One-year survival (failed EVAR 94% vs no EVAR 82%; P = .756) was similar between groups. CONCLUSIONS PM-F/BEVAR is a safe and effective treatment for patients with aneurysms involving the renal-mesenteric arteries in the setting of prior failed EVAR where additional technical challenges may be present. Additional follow-up is warranted to demonstrate long-term efficacy, but early results are encouraging and similar to those using CMDs.

Abstract
OBJECTIVE The need for open surgical conversion (OSC) after failed endovascular aortic aneurysm repair (EVAR) persists, despite expanding endovascular options for secondary intervention. The VASCUNExplanT project collected international data to identify risk factors for failed EVAR, as well as OSC outcomes. This retrospective cross sectional study analysed data after OSC for failed EVAR from the VASCUNET international collaboration. METHODS VASCUNET queried registries from its 28 member countries, and 17 collaborated with data from patients who underwent OSC (2005 - 2020). Any OSC for infection was excluded. Data included demographics, EVAR, and OSC procedural details, as well as post-operative mortality and complication rates. RESULTS There were 348 OSC patients from 17 centres, of whom 33 (9.4%) were women. There were 130 (37.4%) devices originally deployed outside of instructions for use. The most common indication for OSC was endoleak (n = 143, 41.1%); ruptures accounted for 17.2% of cases. The median time from EVAR to OSC was 48.6 months [IQR 29.7, 71.6]; median abdominal aortic aneurysm diameter at OSC was 70.5 mm [IQR 61, 82]. A total of 160 (45.6%) patients underwent one or more re-interventions prior to OSC, while 63 patients (18.1%) underwent more than one re-intervention (range 1 - 5). Overall, the 30 day mortality rate post-OSC was 11.8% (n = 41), 11.1% for men and 18.2% for women (p = .23). The 30 day mortality rate was 6.1% for elective cases, and 28.3% for ruptures (p < .0001). The predicted 90 day survival for the entire cohort was 88.3% (95% CI 84.3 - 91.3). Multivariable analysis revealed rupture (OR 4.23; 95% CI 2.05 - 8.75; p < .0001) and total graft explantation (OR 2.10; 95% CI 1.02 - 4.34; p = .04) as the only statistically significant predictive factors for 30 day death. CONCLUSION This multicentre analysis of patients who underwent OSC shows that, despite varying case mix and operative techniques, OSC is feasible but associated with significant morbidity and mortality rates, particularly when performed for rupture.

Abstract
EVAR (endovascular aortic repair) is the most common method for treating an abdominal aortic aneurysm, but according to the latest findings it carries the risk of subsequent complications. These can be caused by (late) aneurysm sac growth. If conservative and surgical therapies fail to treat the aneurysm sac growth, open conversion is necessary to prevent aneurysm rupture. There are several options for open conversion, in which the EVAR prosthesis can be completely preserved or is (partially) removed. Late open semi-conversion with complete in-situ preservation of the EVAR-prosthesis and gathering of the aneurysm sac are a less invasive method than complete conversion and may be performed instead for selected patients. The aim of the present work is to present the surgical method, including indications and technical information, as well as the presentation of the results in our recent patient collective.All patients semi-converted in our department of vascular surgery and phlebology due to (type II) endoleak were included. All data are presented as n (%) or median (range).Between 6/2019 and 3/2023, 13 patients underwent semi-conversion 6 (2-12) years (median, range) after the initial EVAR. The aneurysm sac diameter at the time of semi-conversion was 69 mm (58-95 mm), the operating time was 114 min (97-147 min), the blood loss was 100 ml (100-1500 ml). Five (38%) patients received blood transfusion intraoperatively and 2 (15%) postoperatively. The stay in the intensive care unit lasted 1 (1-5) days, the hospitalisation time was 8 (6-11) days. Postoperative complications were intestinal atony (3 [23%], 1 [8%] with nausea/emesis and gastric tube insertion), anaemia (2 [15%]), hyponatraemia (2 [15%]), delirium (1 [8%]), COVID-19 infection (1 [8%]) and 1 [8%] intra-abdominal postoperative bleeding with the indication for surgical revision and the transfusion of 8 erythrocyte concentrates.Semi-conversion is a safe and practicable surgical method with few severe complications for a selected group of patients, which should be considered as an alternative to more invasive methods with (partial) removal of the EVAR-prosthesis. Further long-term studies comparing semi-conversion to full conversion are needed to demonstrate its benefits.

Open Conversion with Explantation of Stent Grafts After Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm. Ann Vasc Surg 2023:S0890-5096(23)00523-X. [PMID: 37536432 DOI: 10.1016/j.avsg.2023.07.094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 07/04/2023] [Accepted: 07/06/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Although endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is widely used worldwide, the fact that it is associated with increased rates of reintervention has been considered a problem. This study aimed to analyze the outcomes of primary open AAA repair and open conversion with explantation of stent grafts after EVAR. METHODS In this retrospective study, we enrolled 1,120 patients (open repair, n = 664; EVAR, n = 456) who underwent AAA repair at Kobe University from 1999 to 2019. Of the 664 patients who underwent open repair, 121 (patients who underwent primary open repair (POR) as a concomitant procedure and patients with ruptured AAA) were excluded from the study. The outcomes of POR were compared with those of open conversion with explantation of stent grafts. RESULTS Of the 543 patients who underwent open repair, 513 underwent POR and 30 underwent open conversion with explantation of stent grafts. The operation time for POR was significantly less than that for open conversion with explantation. During surgery, patients who underwent open conversion with explantation required significantly more transfusions of red cell concentrate, fresh frozen plasma, and platelet concentrate than those who underwent POR. Overall, 30 patients who underwent open conversion with explantation required a total of 48 reinterventions before surgery. Hospital mortality rates were 0.7% and 0% in the POR and open conversion with explantation groups, respectively (P = 0.62). Although overall survival at 5 years in the POR group was significantly better than that in the open conversion with explantation group (89.3 ± 1.7% vs. 79.5 ± 9.6%; P = 0.01), there were no significant differences between the 2 groups regarding the freedom from aortic event (hospital death, reintervention, and aortic death). According to the multivariate analysis, open conversion with explantation was not an independent risk factor for late death. There were 20 patients who were hesitant to undergo OCE, although we recommended OCE. In a subgroup analysis, the overall mean cost borne by patients who underwent EVAR was approximately 2.3 times higher compared with that borne by patients who underwent POR. CONCLUSIONS Although demanding, both early and long-term outcomes of OCE have been favorable in our present study. OCE is highly recommended in patients with persistent sac enlargement after EVAR.

Clinical presentation, operative management, and long-term outcomes of rupture after previous abdominal aortic aneurysm repair. J Vasc Surg 2023; 77:396-405.e7. [PMID: 36272507 DOI: 10.1016/j.jvs.2022.08.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 07/30/2022] [Accepted: 08/08/2022] [Indexed: 11/05/2022]
Abstract
OBJECTIVE The aim of the present study was to evaluate the presentation trends, intervention, and survival of patients who had been treated for late abdominal aortic aneurysm rupture (LAR) after open repair (OR) or endovascular aortic aneurysm repair (EVAR). METHODS We reviewed the clinical data from a single-center, retrospective database for patients treated for LAR from 2000 to 2020. The end points were the 30-day mortality, major postoperative complication, and survival. The outcomes between LAR managed with EVAR (group I) vs OR were compared (group II). RESULTS Of 390 patients with infrarenal aortic rupture, 40 (10%) had experienced aortic rupture after prior aortic repair and comprised the LAR cohort (34 men; age 78 ± 8 years). LAR had occurred before EVAR in 30 and before OR in 10 patients. LAR was more common in the second half of the study with 32 patients after 2010. LAR after prior OR was secondary to ruptured para-anastomotic pseudoaneurysms. After initial EVAR, LAR had occurred despite reintervention in 17 patients (42%). The time to LAR was shorter after prior EVAR than after OR (6 ± 4 vs 12 ± 4 years, respectively; P = .003). Treatment for LAR was EVAR for 25 patients (63%; group I) and OR for 15 (37%, group II). LAR after initial OR was managed with endovascular salvage for 8 of 10 patients. Endovascular management was more frequent in the latter half of the study period. In group I, fenestrated repair had been used for seven patients (28%). Salvage for the remaining cases was feasible with EVAR, aortic cuffs, or limb extensions. The incidence of free rupture, time to treatment, 30-day mortality (8% vs 13%; P = .3), complications (32% vs 60%; P = .1), and disposition were similar between the two groups. Those in group I had had less blood loss (660 vs 3000 mL; P < .001) and less need for dialysis (0% vs 33%; P < .001) than those in group II. The median follow-up was 21 months (interquartile range, 6-45 months). The overall 1-, 3-, and 5-year survival was 76%, 52%, and 41%, respectively, and was similar between groups (28 vs 22 months; P = .48). Late mortality was not related to the aorta. CONCLUSIONS LAR after abdominal aortic aneurysm repair has been encountered more frequently in clinical practice, likely driven by the frequency of EVAR. However, most LARs, including those after previous OR, can now be salvaged with endovascular techniques with lower morbidity and mortality.

Abstract
OBJECTIVE The increasing use of endovascular aneurysm repair (EVAR) appears to be associated with the burden of vascular endograft infections. Complete stent graft explantation is recommended but leads to significant mortality. This study aimed to assess the technical challenges, complications, and mortality rate following infected endograft explantation. METHODS Patients who underwent abdominal aortic endograft explantation for infection at the Bordeaux University Hospital from July 2008 to December 2020 were included retrospectively in this single centre observational study. The diagnosis was established based on the MAGIC criteria. The primary endpoint was 30 day mortality. Secondary endpoints were 90 day and in hospital mortality, survival, and re-infection. RESULTS Thirty-four patients were included, median age 69 years (interquartile range [IQR] 65, 76), with four (12%) treated as an emergency. The median time from EVAR to explantation was 17.5 months (4.5 - 36.3). In situ reconstruction was carried out with prosthetic grafts in 24 patients (71%, including 23 antimicrobial grafts combining silver and triclosan), and biological grafts in 10 (five femoral veins, four arterial allografts, three bovine patches, one biosynthetic graft). Seventeen aorto-enteric fistulae (AEnF) were addressed with direct repair of the intestinal tract (n = 10/17; 59%) or resection and anastomosis (n = 7/17; 41%). The culture was polymicrobial in 12 patients (35%) and remained sterile in four (12%). The 30 day and in hospital mortality rates were 21% (n = 7) and 27% (n = 9). Twenty-five patients (73%) presented with early post-operative complications, requiring 16 revision procedures (47%). Over a median follow up of 16.2 months (IQR 8.3, 33.6), the mortality rate was 35% (n = 12; 11 aortic related; 32%), with two re-infections (6%), both after biological reconstruction (one for an AEnF). CONCLUSION Early morbidity and mortality remain high after complete infected endograft explantation, even in a high volume centre. Comparison with other treatment modalities in large multicentre cohorts might be of interest.

Open conversion after failed endovascular aneurysm repair is increasing and its 30-day mortality is higher than that after primary open repair. J Vasc Surg 2022; 76:1502-1510. [PMID: 35709860 DOI: 10.1016/j.jvs.2022.04.056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 03/26/2022] [Accepted: 04/27/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) has become the preferred treatment of abdominal aortic aneurysms (AAAs). Recent studies have demonstrated that cases of EVAR failure repair and subsequent open conversion have increased. The aim of the present study was to evaluate the national trend of annual cases and assess the 30-day outcomes of conversion to open repair after failed EVAR compared with primary open repair. METHODS The National Surgical Quality Improvement Program database was queried for relevant Current Procedural Terminology and International Classification of Diseases, Ninth and Tenth Revision, codes to identify patients who had undergone conversion to open repair or primary open repair of nonruptured AAAs from 2009 to 2018. The annual trend of cases was assessed, and the perioperative outcomes of both procedures were compared. Multivariable logistic regression analyses were conducted to identify independent perioperative factors associated with mortality. RESULTS Of the 9635 patients with nonruptured AAAs included in the present analysis, 9250 had undergone primary repair and 385 had required open conversion. During the 10-year period, the annual number of cases of open conversion had steadily increased and that of primary repair had decreased. The incidence of postoperative complications was similar between both groups, except for cardiac arrest, which had occurred more frequently in the open conversion group. The 30-day mortality was higher in the open conversion group than in the primary group (9.6% vs 3.9%; P < .0001). Open conversion was also independently associated with higher odds of death (adjusted odds ratio [OR], 2.1; 95% confidence interval [CI], 1.8-2.4; P < .0001). When the average mortality in both groups was compared between the first and last 5 years, no difference was found (open conversion: 9.8% vs 9.5% [P = 1.00]; primary repair: 3.6% vs 4.2% [P = .19]). Other perioperative factors independently associated with mortality included increased age (OR, 1.8; 95% CI, 1.5-2.1; P < .0001), American Society of Anesthesiologists class ≥III (OR, 2.7; 95% CI, 1.1-6.6; P = .029), insulin-dependent diabetes (OR, 2.0; 95% CI, 1.2-3.3; P = .005), chronic obstructive pulmonary disease (OR, 1.4; 95% CI, 1.1-1.8; P = .006), the presence of dyspnea at rest (OR, 3.3; 95% CI, 1.8-6.1; P < .0001), and a high preoperative hematocrit (OR, 0.94; 95% CI, 0.93-0.97; P < .0001). CONCLUSIONS Open conversion to treat nonruptured AAAs after failed EVAR was independently associated with higher mortality. Also, the annual cases of open conversion have continued to increase without any significant changes in postoperative mortality. This highlights the danger of open conversion and stresses the need for better solutions to prevent and manage EVAR failure.

Ann Vasc Surg 2022; 87:1-12. [PMID: 36058454 DOI: 10.1016/j.avsg.2022.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 08/05/2022] [Accepted: 08/15/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVE EVAR conversion(EVAR-c) is increasingly reported and known to be technically complex and physiologically demanding. It has been proposed that pragmatic anthropomorphic measures such as psoas muscle area(PMA) may reliably quantify levels of preoperative frailty and be used to inform point of care clinical decision making and patient discussions for a variety of complex operations. To date, there is mixed data supporting use of PMA as a prognostic factor in fenestrated endovascular and open AAA repairs; however, no literature exists evaluating the impact of preoperative PMA on EVAR-c results. Therefore, the purpose of this study was to review our EVAR-c experience and evaluate the association of PMA with perioperative and long-term mortality outcomes. METHODS A retrospective single-center review of all AAA repairs was performed(2002-2019) and EVAR-c procedures were subsequently analyzed(n=153). Cross-sectional PMA at the mid-body of the L3 vertebrae was measured. The lowest PMA tertile was used as a threshold value to designate patients as having "low" PMA(n=51) and this cohort was subsequently compared to subjects with "normal" PMA(n=102). Cox proportional hazards modeling was used to estimate covariate association with all-cause mortality. RESULTS Patients with low PMA were older(77 vs. 72 years;p=.002), more likely to be female(27% vs. 5%;p<.001), and had reduced BMI(26 vs. 29kg/m2;p=.002). Time to conversion, total number of EVAR reinterventions prior to conversion and elective EVAR-c presentation incidence were similar; however, patients with low PMA had larger aneurysms(8.3 vs. 7.5cm;p=.01) and increased post-EVAR sac growth(2.3 vs. 1cm;p=.005). Unadjusted inpatient mortality was significantly greater for low PMA patients(16% vs. normal PMA, 5%, p=.02). Similarly, the total number of complications was higher among low PMA subjects(1.5±1.9 vs. normal PMA, 0.9±1.5;p=.02). Although frequency of major adverse cardiovascular events and new onset inpatient hemodialysis were similar, low PMA patients had a more than four-fold increased likelihood of having persistent requirement of hemodialysis at discharge(18% vs. 4%,p=.01). The low PMA group had decreased survival at 1 and 5 years, respectively(77±5%, 65±6% vs. normal PMA, 86±3%, 82%±5%;log-rank p=.03). Low PMA was an independent predictor of mortality with every 100mm2 increase in PMA being associated with a 15% reduction in mortality(HR 0.85,95% CI, .74-.97;p=.02). CONCLUSION Among EVAR-c patients, subjects with low preoperative PMA had higher rates of postoperative complications and worse overall survival. PMA assessments may be a useful adjunct to supplement traditional risk-stratification strategies when patients are being considered for EVAR-c.

Abstract
Objectives We aim to scrutinize our evolving re-intervention strategies following primary endovascular aortic aneurysm repair (EVAR) - EVAR GORE SalvAge Fabric Technique (ARAFAT), aortic sac double breasting with endograft preservation, and stent-graft explantation. Methods We performed 1,555 aortic interventions over the study period, including 910 EVARs. Factors associated with the need for reintervention and the likelihood of chronic fabric fatigue failure (CFFF) were investigated. Using conventional and innovative diagnostic modalities with Prone contrASt enHanced computed tomography Angiography (PASHA), 136 endoleaks (ELs) were identified (15 type I, 98 type II; 18 type III; 5 type IV). Results Forty-four (4.84%) patients underwent re-intervention post-primary EVAR; 18 ARAFATs, 12 double breastings, and 14 explantations. Choice of re-intervention was based on patient fitness and mode of failure. Mean EL detection duration following primary EVAR was 53.3 ± 6.82 months, while mean time to re-intervention was 70.20 ± 6.98 months. The mean sac size before the primary EVAR and re-intervention was 6.00 ± 1.75 cm and 7.51 ± 1.94 cm, respectively. Polyester (61.40%) was the most commonly employed stent-graft material. Use of more than three modular stent-graft components (3.42 ± 1.31, p = 0.846); with the proximal stent-graft diameter of 31.6 ± 3.80 cm (p = 0.651) and the use of iliac limbs more than 17 mm (p = 0.364), all added together are contributing factors. We had one peri-operative mortality following explantation due to sepsis-induced multiorgan failure. Conclusions Our re-intervention strategies matured from stent graft explantation to graft preservation with endovascular relining of the stent-graft. Graft preservation with aortic sacotomy and double breasting were used to manage concealed ELs due to aortic hygroma.

Abstract
OBJECTIVE The prominent use of endovascular stent grafts in the management of abdominal aortic aneurysms is associated with increased descriptions of late complications such as graft infection and endoleaks, which can confer significant morbidity and mortality. Failed endovascular management of late complications often requires open conversion and graft explantation. This systematic review sought to highlight the peri- and post-operative course of patients undergoing aortic graft explants to inform readers of the associated morbidity and mortality of patients undergoing this procedure. METHODS The review was conducted in accordance with PRISMA guidelines. A search of the PubMed, Google Scholar and Ovid MEDLINE databases from January 1995 to April 2021 was performed with a combination of MeSH terms pertaining to endovascular aneurysm repair and open conversion. Articles were screened and included based on pre-determined selection criteria. RESULTS A total of 818 studies were identified, with 41 meeting inclusion criteria. These studies examined a total of 1324 patients, 84.3% of whom were male with a mean age of 74 years at explantation. Mean time to graft explantation was 36 months, with a mean aneurysm size of 66 mm. The majority of aortic explants were performed for persistent endoleaks (68%), and 10% for infection. There was high morbidity with the procedure, with high rates of post-operative complications (mean, 37%) and 30-day mortality (11%). The most common complications included renal (15%), respiratory (12%) and cardiac (9%). Most explanted grafts were first-generation endografts. Morbidity and mortality rates were reduced in patients undergoing elective explants compared to emergent procedures (3.3% compared to 43.4%). CONCLUSION Aortic graft explant remains a highly co-morbid procedure, with high rates of peri- and post-operative complications and mortality. The number of explant procedures reported over the past 25 years has increased, reflecting the prominent use of EVAR in the management of AAAs. Whilst remaining a highly co-morbid procedure, patients undergoing elective explants had markedly reduced rates of mortality and morbidity compared to emergent explants. Thus, clinical focus should be on identifying patients who require graft explantation early to perform these procedures in an elective setting.

Abstract
OBJECTIVES The aim of this study is to compare early and follow-up outcomes of late open conversions (LOC, with complete or partial endograft explantation) and semi-conversions (SC, with endograft preservation) after EVAR in a multicentre experience. MATERIALS AND METHODS All-LOC and SC performed from 1997 to 2020 in 11 vascular centres were compared. Endograft infections or thrombosis were excluded. Primary endpoints were early mortality, and long-term survival estimates. Secondary endpoints were differences in: postoperative complication rates, conversion-related complications during follow-up. RESULTS In the considered period, 347 patients underwent surgery for EVAR complications. Among these, 270 were operated on for endoleaks (222 LOC, 48 SC). The 2 groups were homogeneous in terms of ASA score (3.2±0.7 LOC, 3±0.5 SC; P=.128) and main endograft characteristics (suprarenal fixation, bifurcated/aorto-uni-iliac configuration). Mean age was 75±8 at LOC and 79±7 at SC (P=.009). Reasons for LOC were: 62.2% (138/222) type I endoleak, 21.6% (48/222) type II, 7.7% (17/222) type III, 8.5% (19/222) endotension. Indications for SC were: 64.6% (31/48) type II endoleak, 33.3% (16/48) type I, 2.1% (1/48) type III. Thirty-day mortality was 12.2% (27/222) in the LOC group, and 10.4% (5/48) in the SC group (P=.73). Postoperative complication rate was higher in the LOC group (45.5% vs. 29.2%, P=.04). The estimated survival rate after LOC was 80% at 1 year and 64% at 5 years; after SC 72% at 1 year and 37% at 5 years (log-rank P=.01). During the median follow-up of 21.5 months (inter-quartile range 2.4-61), an endoleak after SC was found in the 38.3% of the cases; sac growth was recorded in the 27.7% of SC patients. CONCLUSIONS SC have an early benefit over LOC in terms of reduced postoperative complications, but a significantly inferior mid-term survival. The high rates of persistent and/or recurrent endoleaks reduce SC durability.

Abstract
Introduction/Objective. The objective was to present the results and technical considerations from high-volume center when performing late open surgical conversion (LOSC) after endovascular aneurysm repair (EVAR) in ruptured abdominal aortic aneurysm (RAAA) patients. Methods. This was a single center retrospective study. LOSC was performed whenever eventual endovascular reintervention failed, was not feasible due to hostile anatomy and unavailability of specific endograft materials, or when patient was hemodynamically unstable necessitating emergent surgery. Results. All previously implanted EVARs had bimodular configuration with suprarenal fixation. Total endograft explantation was performed in 40% of patients. Hospital mortality was 20%. Both patients who died had total endograft explantation with supraceliac clamp lasting more than 30 minutes. 30-day mortality was 30%, with one more patient who died from pulmonary embolism after hospital discharge and two hospital deaths were due to myocardial infarction. Conclusion. LOSC due to RAAA after previous EVAR carries greater mortality for the patient, suggesting multifactorial impacts on the outcome. The appropriate choice of surgical method and technical success are of ultimate importance, with total graft explantation having negative impact on patient?s survival.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) shrinkage after endovascular aortic aneurysm repair (EVAR) is a surrogate marker for successful exclusion. Our study characterized aneurysm sac remodeling after EVAR to identify a pattern that may be associated with benign AAA behavior and would safely allow a less rigorous follow-up regimen after EVAR. METHODS Elective infrarenal EVARs performed between 2008 and 2011 at our institution were retrospectively reviewed. AAA sac diameters using the minor axis measurement from ultrasound imaging or computer tomography angiogram imaging were compared with the baseline diameter from the 1-month postoperative computer tomography angiogram. The primary outcome was a composite of freedom from postoperative reintervention or rupture. We compared those with AAA sacs who regressed to predefined minimum diameter thresholds with those who did not. Outcomes were plotted with Kaplan-Meier curves and compared using log-rank testing and Fine-Gray regression using death as a competing risk, clustered on graft type. For patients whose AAA reached the minimum sac diameter, landmark analysis evaluated ongoing size changes including further regression and sac re-expansion. RESULTS A total of 540 patients (aged 75.1 ± 8.2 years; 82.0% male) underwent EVAR with an average preoperative AAA size of 55.2 ± 11.5 mm. The median postoperative follow-up was 5.3 years (interquartile range, 1.4-8.7 years) during which 64 patients underwent reintervention and 4 ruptured. AAA sac regression to ≤40 mm in diameter was associated with improved freedom from reintervention or rupture overall (log-rank, P < .01), which was maintained after controlling for the competing risk of death (P < .01). In 376 patients (70%) whose aneurysm sac remained >40 mm, 99 reinterventions were performed on 63 patients. Of 166 (31%) patients whose sac regressed to ≤40 mm, only 1 patient required a reintervention, and no one ruptured. The mean time to a diameter of ≤40 mm was 2.3 ± 1.9 years. Only eight patients (5%) developed sac re-expansion to >45 mm; all but two occurred at least 3 years after initially regressing to ≤40 mm. CONCLUSIONS In long-term follow-up, patients whose minimum AAA sac diameter regressed ≤40 mm after EVAR experienced a very low rate of reintervention, rupture, or sac re-expansion. Most sac re-expansion occurred at least 3 years after reaching this threshold and did not result in clinical events. Increasing follow-up frequency up to 3-year intervals once the AAA sac regresses to 40 mm would carry minimal risk of aneurysm-related morbidity.

Abstract
We have described our technique of open partial conversion (OPC; n = 5) with aortic banding and endograft preservation for the treatment of type II endoleaks. OPC significantly reduced the aortic clamping time (5.0 vs 32.5 minutes; P = .01) relative to endograft explantation (n = 2). Cross-clamping was avoided entirely in three of the procedures. The patients treated with OPC showed a trend toward a decreased operative time (4.8 vs 5.9 hours) and shorter hospital stay (5.7 vs 7.4 days). Follow-up computed tomography scans were available for three of the five OPC patients, which showed resolution of the type II endoleak. The findings from the present study have further demonstrated the safety of OPC for the treatment of type II endoleaks.

Abstract
OBJECTIVE The midterm results of endovascular abdominal aortic aneurysm repair (EVAR) with aortic side branch coil embolization during EVAR was evaluated. METHODS Our center began coil embolization for all patent inferior mesenteric artery (IMA) and lumbar artery (LA) with an inner diameter more than 2.0 mm during EVAR since June 2015. When four or more LA were patent, coil embolization for LA with inner diameter 2.0 mm or less was done. EVAR without aortic side branches coil embolization was performed for 59 patients prior to June 2015 (control group) and 79 patients underwent EVAR with coil embolization during EVAR (coil group). The success rate of coil embolization for IMA and LA was evaluated in coil group. The frequency of type 2 endoleak (T2EL), freedom from aneurysm sac expansion (5 mm or more) rate and the rate of the aneurysm sac shrinkage (10 mm or more) were compared between the coil and control groups. Additionally, multiple logistic regression analysis for all patients was conducted to analyze whether IMA patency and the number of patent lumbar artery at the end of EVAR were the risk factors of the aneurysm sac expansion of 5 mm or more. RESULTS The success rate of IMA coil embolization was 96.4% and that of LA was 74.5%. Compared to the control group, the frequency of T2EL was significantly lower in coil group at 7 days (1.3% vs. 60.4%, P <0.0001) and at 6 months (2.1% vs 38.2%, P <0.0001) after EVAR. The freedom from aneurysm sac expansion rate was significantly better in the coil group at 5 years (100% in coil group and 65.2% in control group, P = 0.002). The rate of aneurysm sac shrinkage was significantly better in coil group (15.5% vs. 2.0% at 1 year, 42.8% vs. 6.3% at 2 years and 53.4% vs. 17.8% at 3 years, p = 0.0007). The risk of aneurysm sac expansion of 5 mm or more was estimated to be 11 times greater when the IMA was patent, and 4.9 times greater when 3 or more LAs were patent at the end of EVAR. CONCLUSION When IMA was occluded and the number of patent LA became 2 or less by aortic side branch coil embolization during EVAR, favorable mid-term results were safely obtained and good long-term result could be expected with EVAR.

[PMID: 34474963 DOI: 10.1016/j.ejvs.2021.07.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 06/03/2021] [Accepted: 07/05/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVE To report the outcome of fenestrated and branch endovascular aortic repair (FEVAR-BEVAR) for asymptomatic and acute symptomatic proximal aortic pathology in patients with prior open (OSR) or endovascular (EVAR) abdominal aortic aneurysm (AAA) repair. METHODS This was a single centre retrospective study of consecutive patients with non-ruptured (asymptomatic and acute symptomatic) proximal aortic pathology after prior OSR or EVAR treated between December 2007 and February 2020. The primary endpoint was 30 day/in hospital mortality. Secondary endpoints were technical success, primary clinical success, and Kaplan-Meier estimates of medium term survival and freedom from re-intervention. Data are presented as median (interquartile range [IQR]). The effect of covariates on medium term survival was estimated using multivariable (Cox proportional hazards model) analysis. A p value < .05 was considered to be statistically significant. RESULTS Ninety-two patients (83 men; median age 75 years [IQR 71 - 80 years]; median diameter 73 mm [IQR 64 - 89 mm]; 82 elective, 10 acute) underwent FEVAR-BEVAR after prior OSR (n = 47) or EVAR (n = 45). Indications for intervention were aneurysmal degeneration with or without type 1a endoleak (n = 57; four juxtarenal [JR] AAA, 21 extent II/III, 32 extent IV thoraco-abdominal aortic aneurysms); type 1a endoleak alone (n = 27) and to create a more durable repair after acute infrarenal EVAR (n = 8; JRAAA). In total, 348 renovisceral vessels were targeted for preservation and 324 were stent grafted. Twenty-four unstented vessels comprised one bypass, 11 scallops and six fenestrations intentionally not stent grafted, two vessels occluded before graft implantation, and four vessels occluded intra-operatively. Primary technical success was 95.6%. The thirty day mortality rate was 1.1% and one patient each (1.1%) required permanent dialysis or developed temporary spinal cord ischaemia. Early primary clinical success was 94.6%. Median follow up was 36 months (IQR 23 - 64 months). Estimated overall survival (± standard error) at one, two, and three years was 86% ± 4%, 85% ± 4%, and 70% ± 5%, respectively. Multivariable analysis did not demonstrate any independent predictors of survival. Four target vessels occluded during follow up. Nineteen patients underwent 28 late re-interventions, with almost half performed for issues arising distal to the FEVAR-BEVAR. Patients treated with a cuff were statistically significantly more likely to require distal re-intervention compared with those treated by relining (9/49 vs. 1/43, p = .018 [odds ratio 9.3, 95% confidence interval 1.2 - 423]). In patients with prior EVAR alone, this did not reach statistical significance (cuff 7/25 vs. relining 1/20, p = .059 [odds ratio 7.1, 95% confidence interval 0.8 - 350]). Estimated freedom from re-intervention at one, two, and three years was 88% ± 3%, 81% ± 4%, and 81% ± 4%, respectively. CONCLUSION FEVAR-BEVAR after prior OSR or EVAR is associated with low peri-operative morbidity and mortality, and acceptable medium term survival and freedom from re-intervention. Treatment with a FEVAR-BEVAR cuff is associated with a higher requirement for distal re-intervention than relining of the original repair.

Abstract
We report a case of combined types IIIb and Ia endoleak that developed 6 years after endovascular aneurysm repair (EVAR) with the Endurant II® endograft for abdominal aortic aneurysm (AAA). The patient presented with post-EVAR AAA rupture and underwent emergency open repair. We observed types IIIb and Ia endoleak and successfully performed felt banding to preserve the stent graft. Type IIIb endoleak with the Endurant® endograft is rare, and treatments have not been fully established. We summarized the case reports regarding type IIIb endoleak with the Endurant® endograft and mainly discussed the treatments.

A Canadian multicenter experience describing outcomes after endovascular abdominal aortic aneurysm repair stent graft explantation. J Vasc Surg 2021; 74:720-728.e1.

Abstract
BACKGROUND Most studies describing the outcomes after endovascular abdominal aortic aneurysm repair (EVAR) explantation have been from single, high-volume, centers. We performed a multicenter cross-Canadian study of outcomes after EVAR stent graft explantation. Our objectives were to describe the outcomes after late open conversion and EVAR graft explantation at various Canadian centers and the techniques and outcomes stratified by the indication for explant. METHODS The Canadian Vascular Surgery Research Group performed a retrospective multicenter study of all cases of EVAR graft explantation at participating centers from 2003 to 2018. Data were collected using a standardized, secure, online platform (RedCap [Research Electronic Data Capture]). Univariate statistical analysis was used to compare the techniques and outcomes stratified the indication for graft explantation. RESULTS Patient data from 111 EVAR explants collected from 13 participating centers were analyzed. The mean age at explantation was 74 years, the average aneurysm size was 7.5 cm, and 28% had had at least one instructions for use violation at EVAR. The average time between EVAR and explantation was 42.5 months. The most common indication for explantation was endoleak (n = 66; type Ia, 46; type Ib, 2; type II, 9; type III, 2; type V, 7), followed by infection in 20 patients; rupture in 18 patients (due to type Ia endoleak in 10 patients, type Ib in 1, type II in 1, type III in 2, and type V in 1), and graft thrombosis in 7 patients. The overall 30-day mortality was 11%, and 45% of the patients had experienced at least one major perioperative complication. Mortality was significantly greater for patients with rupture (33.3%) and those with infection (15%) compared with patients undergoing elective explantation for endoleak (4.5%; P = .003). The average center volume during the previous 15 years was 8 cases with a wide range (2-19 cases). A trend was seen toward greater mortality for patients treated at centers with fewer than eight cases compared with those with eight or more cases (19% vs 9%). However, the difference did not reach statistical significance (P = .23). Overall, 41% of patients had undergone at least one attempt at endovascular salvage before explantation, with the highest proportion among patients who had undergone EVAR explantation for endoleak (51%). Only 22% of patients with rupture had undergone an attempt at endovascular salvage before explantation. CONCLUSIONS The performance of EVAR graft explantation has increasing in Canada. Patients who had undergone elective explantation for endoleak had lower mortality than those treated for either infection or rupture. Thus, patients with an indication for explanation should be offered surgery before symptoms or rupture has occurred. A trend was seen toward greater mortality for patients treated at centers with lower volumes.

Abstract
AIM The study was aimed at assessing efficacy and safety of endovascular treatment of abdominal aortic aneurysms based on 11-year experience with implantation of stent grafts. PATIENTS AND METHODS We retrospectively analysed outcomes of treatment of 242 patients with abdominal aortic aneurysm during the period from 2008 to 2019. Of these, 210 (86.78%) were males, mean age 69.32±7.36 years. Diagnosis was made using colour duplex scanning and contrast-enhanced multislice spiral computed tomography, with implanting the following stent grafts: Ella - 44, Ovation Prime - 33, Anaconda - 13, Endurand - 77, Aortix - 2, Zenith - 33, Seal - 39, with one endoprosthesis placement failed. Assessing safety of the operation, we took into consideration lethality due to aortic rupture/thrombosis. Efficacy was taken to mean technical success of the operation (implantation of all components of the endograft without switch to open surgery), the number of reoperations. RESULTS Technical success of the operation was achieved in 98.35% of cases. In 1 case due to pronounced arterial calcification for technical reasons we failed to position the stent graft and in another case - the contralateral leg of the Ella prosthesis. The early postoperative period revealed: type A1 endoleak - 3.7%, type IB - 4.13%, type IIA - 6.6%, type IIB - 4.54%, type III - 0.83%, type IV - 0.83%. Repeat operations were performed in 20 (8.2%) patients within 30 days after the intervention and in 32 (13.22%) in the remote period. In the early postoperative period two conversions were performed: 1) iliorenal bypass grafting for restoration of blood flow through the renal artery occluded by endoprosthesis wall; 2) evacuation of retroperitoneal haematoma due to rupture of the common femoral artery. Lethality during the whole period of follow up amounted to 32 (13.22%) cases. Of these, due to aortic complications 4.54% (n=11) and due to accompanying pathology 8.67% (n=21). A direct correlation was revealed between the aortic diameter and duration of the operation which in turn increases the risk of complications requiring re-operation or resulting in a lethal outcome (RR - 1; 95% CD 1- 1; p=0.026). CONCLUSION Our experience showed high safety and efficacy of stent graft implantation in treatment of patients with abdominal aortic aneurysms and high surgical risk.

Abstract
Abdominal aortic aneurysm rupture after endovascular aneurysm repair (EVAR) is rare, but remains a significant limitation of endovascular technology. Preservation of the endograft during open conversion of a post-EVAR rupture has been shown to be associated with improved perioperative outcomes. An interposition Dacron graft with felt pledgets is a novel bail-out option for the open reconstruction of a type III endoleak with total endograft preservation. This technique is useful in high-risk patients presenting with ruptured abdominal aortic aneurysm after EVAR and no clear source of endoleak.

Abstract
Abdominal aortic aneurysm (AAA) is a disease of the elderly which may result in aneurysm rupture if not treated in a timely manner. The incidence of AAA has increased in part due to patient and physician education, ultrasound screening, and liberal use of computed tomography imaging in conjunction with an aging population. Endovascular aneurysm repair has become the preferred treatment for surgeons and interventionalists. When endografts are placed outside of device-specific instructions for use, the risk of endoleak development is significantly increased. Open surgical repair of Type Ia endoleaks is recommended when endovascular options have been exhausted. Open surgical repair of Type Ia endoleaks provides acceptable perioperative morbidity and mortality rates, long-term durability, and low reintervention rates when performed in the elective setting.

Abstract
BACKGROUND Delayed open conversion (OpC) after endovascular aortic aneurysm repair (EVAR) is becoming increasingly common worldwide. We reviewed our experience to characterize the perioperative spectrum of OpC repairs. MATERIALS AND METHODS A retrospective analysis of a prospectively maintained institutional database to identify patients who underwent late OpC after failed EVAR was performed. Patient and aneurysm baseline characteristics, mechanism of failure, perioperative details, including type of repair/complications/survival, and late outcomes were examined. RESULTS From January 2003 to January 2020, 38 male patients (mean age, 75 ± 7 years; range, 60-90) required late OpC. Interval time from initial EVAR to OpC was 63.6 ± 33.8 months (range, 17-120). Mean diameter of the aneurysms was 82.2 ± 22.1 mm before OpC compared with 62.9 ± 13 mm before endograft implantation. Mechanisms of failure were type Ia, Ib, II, and III endoleaks in 14 (36.8%), 9 (23.7%), 4 (10.5%), and 1 (2.6%) patient(s), respectively; infection in 3 (7.9%), leg ischemia in 2 (5.3%), and multiple causes in 5 (13.2%) patients. We observed 4 (10.5%) asymptomatic, 16 (42.1%) symptomatic, and 18 (47.3%) ruptured aneurysms. Four patients (10.5%) had stable contained ruptures, whereas the remaining 13 (34.2%) and 1 additional patient (2.6%) with aortoenteric fistula presented with hemorrhagic shock (class ≥II). Total endograft explantation, endograft preservation, or proximal/distal partial graft removal was performed in 16 (42.1%), 10 (26.3%), and 2 (5.2%)/9 (23.7%) of patients, respectively. Technical success was 100%, excluding an early postaortic clamping death. Overall, 30-day mortality was 21.1% (8 of 38) and significantly higher in patients with hemorrhagic shock or hemodynamic instability at presentation (P = 0.04 and P = 0.009, respectively) and in patients who had endografts with hooks/barbs or experiencing higher postoperative complication rate (P = 0.02 and P = 0.006, respectively). By definition, procedure success was 81.1%. Mean follow-up was 37.6 ± 39.8 months. By the end of the study, we recorded 11 deaths (2 were aneurysm related). CONCLUSIONS Despite high technical success, OpC has a significant mortality in patients presenting with hemorrhagic shock and had active fixation endografts or experiencing high complication rate. Many other confounding factors may play a role.

Abstract
OBJECTIVE We present the 5-year results of a prospective regulatory study of the INCRAFT device, a low-profile endovascular stent graft system for repair of abdominal aortic aneurysms. METHODS This was an open-label prospective nonrandomized single-arm study enrolling in centers in the United States and Japan. The primary effectiveness outcome was successful aneurysm treatment and the primary safety outcome was the incidence of major adverse events at 30 days after the procedure. Major long-term outcomes were mortality, reintervention, adverse limb outcomes, and suprarenal stent fracture. RESULTS One hundred and ninety patients (mean age, 73.8 ± 7.6 years; 90% male; 69% white and 30% Asian) were enrolled from 32 centers throughout the United States and Japan. Minimal access vessel size was less than 7 mm on both sides in 43.9% of the study cohort. Thirty-day major adverse events occurred in 3.2% of patients (6/190). Periprocedural technical success was 94.1% (176/187). Successful aneurysm treatment was 100% at 30 days and 87.9% at 1 year. Two patients required open conversion for thromboembolic complications, 3 developed new type I or III endoleaks, and 7 experienced graft or limb occlusion. Freedom from graft occlusion was 96 ± 2% at 1 year and 94 ± 2% at 5 years. Freedom from stent fracture was 97 ± 1% at 1 year and 87 ± 3% at 5 years. Freedom from aneurysm-related mortality was 99 ± 1% at 1 and 5 years. CONCLUSIONS This study demonstrates good efficacy and safety and a very low rate of aneurysm related deaths with the INCRAFT device in a population with a high proportion of challenging anatomy.

Surgical "New Aortic Carrefour Technique" for Late Open Conversion After Endovascular Aortic Repair. Ann Vasc Surg 2020; 70:434-443. [PMID: 32599108 DOI: 10.1016/j.avsg.2020.06.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 06/11/2020] [Accepted: 06/12/2020] [Indexed: 01/19/2023]
Abstract
BACKGROUND The aim of the study is to report the early and midterm outcomes of late open conversion (LOC) after endovascular aortic repair (EVAR) using the "new aortic carrefour technique" (NACT) for preservation of the stent-graft iliac limbs. Late conversions were defined as explants >6 months after previous EVAR. METHODS Patients treated for elective or urgent LOC after EVAR with the NACT at a single center (2009-2019), and with ≥6 months of follow-up, were included. Briefly, after completing the proximal aortic anastomosis, the endograft iliac limbs were truncated and sutured together to create a "new aortic carrefour" (Veraldi's technique). A Dacron-knitted straight graft was therefore sutured to the newly created aortic bifurcation. Outcomes of interest were as follows: immediate technical success, intraoperative characteristics, and reinterventions. Results are reported as the number (and percentages) or median (and interquartile range [IQR]). RESULTS During the study period, 433 patients underwent standard EVAR for abdominal aortic aneurysm and 20 underwent LOC. Of these, 9 consecutive patients were deemed suitable and treated with NACT. The indication for conversion was endoleak in 6 (type IA n = 1, type II n = 4, type III n = 1), complete graft thrombosis (n = 2), and one case of sac enlargement without any clear signs of endoleak at computed tomography angiography. Of these cases, six were treated electively, while three were treated in urgent setting including one case of rupture. The median procedure, aortic cross-clamping, and distal anastomosis times were 280 minutes (IQR: 225-290), 24 minutes (IQR: 22-29), and 15 minutes (IQR: 14-18), respectively. The median blood loss was 1,600 mL (IQR: 700-1,900), and the median hospital stay was 8 days (IQR 7-12). None of the patients died and neither required unplanned reintervention within 30 days. At a median imaging follow-up of 13 months (IQR 8-43), there were no reinterventions due to residual leaks or technical defects. One patient died during follow-up, and the recorded cause of death was heart failure. CONCLUSIONS The use of the NACT with preservation of the original endograft iliac limbs for LOC after EVAR is a safe and feasible technique, which results in a low perioperative morbidity and mortality rate in selected patients. The technique is effective during midterm follow-up and might represent a valuable tool to expand the armamentarium of vascular surgeons for surgical regrafting after EVAR.

Abstract
OBJECTIVE Three of four patients with infrarenal abdominal aortic aneurysm are now treated with endovascular aneurysm repair (EVAR). The incidence of secondary procedures and surgical conversions is increasing for a population theoretically unfit for open surgery. The indications and outcomes of late open surgical conversions after EVAR in a high-volume tertiary vascular unit are reported. METHODS This retrospective single-center study includes all patients who underwent a late open conversion between January 1996 and July 2018. Data were collected from records on patient demographics, operative indications, surgical strategy, perioperative outcomes, and medium-term survival. RESULTS Sixty-two consecutive patients (88.7% male) with a mean age of 77.5 years are included. The median duration since index EVAR was 38.5 months; 65% of stent grafts requiring late open conversion had suprarenal fixation. Indications included 22.6% type IA, 16.1% type IB, and 45.2% type II endoleaks; 12.9% graft thrombosis; and 14.5% endoprosthesis infection. Complete endograft explantation was performed in 37.1% of patients and a partial explantation in 54.8%, whereas 8.1% of stent grafts were wholly preserved in situ. Overall 30-day mortality was 12.9% (n = 8) in the cohort and 2.7% for elective patients. The all-cause morbidity rate was 40.1%, and the median length of hospital stay was 9 days. After follow-up of 28.4 months (range, 1.8-187.3 months), all-cause survival was 58.8%. Avoidance of aortic clamping (P = .006) and elective procedures (P = .019) were associated with a significant reduction in the length of hospital stay. Moreover, the 30-day mortality (P = .002), occurrence of postoperative renal dysfunction (P = .004), and intestinal ischemia (P = .017) were increased in the emergency setting. Excluding cases with rupture or infection, survival estimates were 97%, 97%, and 71% at 1 year, 2 years, and 5 years, respectively. CONCLUSIONS Technically more complex than primary open surgery, late open conversion is a procedure that generates an acceptable perioperative risk when it is performed in a high-volume aortic surgical center. Elective open conversion is associated with excellent early and late outcomes. Endograft preservation strategies decrease perioperative morbidity.

Abstract
OBJECTIVE With the increasing use of endovascular aortic aneurysm repair (EVAR), open repair after aortic stent grafting is of growing interest. The surgical conversion treatment may be a very challenging process with high mortality and in-hospital complication rates. The aim of this article is to present our experience in patients with EVAR failure treated by minimally invasive open conversion (MOC) and its technical aspects. METHODS A retrospective study was conducted on a prospectively compiled computerized database of consecutive patients treated by MOC at our institution between May 2014 and June 2018. Indications for treatment were endoleaks with sac growth at least >5 mm in the last 6 months and failure of previous endovascular tentative for aneurysm sealing. Demographics of the patients, reason for conversion, previous endovascular procedures, surgical outcomes, and survival were reviewed. MOC was performed by a small abdominal incision, infrarenal clamping, and partial explantation of the endograft in all patients. RESULTS A total of 10 patients were treated during the study period. The mean interval to MOC after EVAR was 45.1 months (range, 14-128). Indications for MOC included type Ia endoleak in three patients (30%), persistent type II EL in four (40%), and type III EL in one patient (10%), indeterminate or type V EL in two (20%). At 30 days, no deaths or reinterventions were reported, and major complication rate was 10% (one postoperative pneumonia). At mean follow-up of 22.9 ± 15.9 months, no reinterventions were described. Death rate was (20%) with one aneurysm-related death (10%) for graft infection 32 months after MOC and one (10%) cardiac event at 18 months. CONCLUSIONS Despite the potential high risk of open conversion, MOC appears to be a safe surgical solution for EVAR failure. This potentially challenging operation may be improved with minimally invasive techniques that are presented.

Abstract
Abstract
OBJECTIVES
Our goal was to report our results of late surgical conversion after endovascular aneurysm repair (EVAR).
METHODS
Variables analysed included baseline data, preinterventional anatomy, type of endovascular intervention, indications for conversion, operative technique, postoperative complications and follow-up survival rate.
RESULTS
Between April 2011 and May 2018, 16 patients with late complications after EVAR underwent open surgical conversion at our institution. The mean age was 73.6 [standard deviation (SD) 8.9] years. There were 3 (18.8%) female patients. In 15 patients, the indication for primary EVAR was abdominal aortic aneurysm, and in 1 patient, chronic abdominal aortic dissection. Five patients underwent secondary EVAR service interventions for endoleak treatment between the index EVAR and the final secondary surgical conversion. Thirteen patients underwent surgery in an elective setting and 3 patients underwent emergency surgery. The mean time from EVAR to open surgical conversion was 6.31 (SD 4.0) years (range 1.2–16.0 years). The most common indication for conversion was endoleak formation (n = 12, 75%), followed by 3 cases of aortic rupture (1 patient with primary type 1 endoleak) and 2 cases of stent graft infection—1 with and 1 without an aortoduodenal fistula. One patient died during emergency open surgery of cardiopulmonary instability. Three patients developed postoperative renal dysfunction with recovery of their renal function before discharge. The in-hospital mortality rate was 12.5%. The median follow-up was 16.5 months (interquartile range 21 months). Freedom from death and aortic reintervention was 100%, respectively. After careful review of the index computed tomography scans for EVAR, the majority of failures could have been anticipated due to trade-offs with regard to length, diameter, morphology, shape and angulation of the proximal and/or distal landing zone.
CONCLUSIONS
Despite being a challenging operation, late surgical conversion after EVAR yields excellent results with regard to outcome and freedom from the need for further aortic interventions. An anticipative strategy adhering to current recommendations for using or refraining from using EVAR in patients with anatomical challenges will help reduce the need for secondary surgical conversions and keep them to minimum.
