Abstract
OBJECTIVES To evaluate technical success, feasibility, and outcomes of endovascular preservation of segmental arteries (SAs) during fenestrated /branched endovascular aortic repair (F/B-EVAR). METHODS A multicenter, retrospective study was conducted on consecutive patients treated with F/B-EVAR and a branch or fenestration for SA preservation. Eleven patients (median age 57, range 45-73; 7 men) were included. RESULTS Twelve SAs were preserved. Stent-grafts were custom-made with fenestrations, branches, or a combination of both in 1, 2, and 5 patients. A t-branch was used in 2 patients and physician-modified thoracic stent-graft with a branch was used in 1 patient. Eight branches and 4 fenestrations were used for the preservation of 12 SAs. Four fenestrations and 1 branch for SAs were not bridged and were left for the perfusion of the corresponding SAs. Technical success was achieved in 10/11 (91%) patients. No early mortality occurred. Early morbidities included renal insufficiency without dialysis in 1 patient and partially delayed paraplegia in 1 patient. Pre-discharge computed tomography angiography (CTA) showed patency of all SAs. No early aortic-related re-interventions were required. The median follow-up was 30 (range 10-88) months. Late death occurred in 1 patient. Two SAs occluded in 1 patient with two un-stented fenestrations at 1-year follow-up CTA. This patient did not develop spinal cord ischemia (SCI). Other SAs remained patent during follow-up. One patient with type IIIc endoleak was treated by relining of bridging stents. CONCLUSION Endovascular preservation of SAs with F/B-EVAR for thoracoabdominal aortic aneurysm is feasible and safe in selected patients and may add to preventive measures for SCI.

Comparison of upper extremity and transfemoral access for fenestrated-branched endovascular aortic repair. J Vasc Surg 2023; 77:704-711. [PMID: 36257344 DOI: 10.1016/j.jvs.2022.10.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 10/07/2022] [Accepted: 10/09/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The use of upper extremity (UE) access is an accepted and often implemented approach for fenestrated/branched endovascular aortic aneurysm repair (F-BEVAR). The advent of steerable sheaths has enabled the performance of F-BEVAR using a total transfemoral (TF) approach without UE access, potentially decreasing the risks of cerebral embolic events. The purpose of the present study was to assess the outcomes of F-BEVAR using UE vs TF access. METHODS Prospectively collected data from nine physician-sponsored investigational device exemption studies at U.S. centers were analyzed using a standardized database. All patients were treated for complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) using industry-manufactured fenestrated and branched stent grafts between 2005 and 2020. The outcomes were compared between patients who had undergone UE vs total TF access. The primary composite outcome was stroke or transient ischemia attack (TIA) and 30-day or in-patient mortality during the perioperative period. The secondary outcomes included technical success, local access-related complications, and perioperative mortality. RESULTS Among 1681 patients (71% men; mean age, 73.43 ± 7.8 years) who had undergone F-BEVAR, 502 had had CAAAs (30%), 535 had had extent IV TAAAs (32%), and 644 had had extent I to III TAAAs (38%). UE access was used for 1103 patients (67%). The right side was used for 395 patients (24%) and the left side for 705 patients (42%). UE access was preferentially used for TAAAs (74% vs 47%; P < .001). In contrast, TF access was used more frequently for CAAAs (53% vs 26%; P < .01). A total of 38 perioperative cerebrovascular events (2.5%), including 32 strokes (1.9%) and 6 TIAs (0.4%), had occurred. Perioperative cerebrovascular events had occurred more frequently with UE access than with TF access (2.8% vs 1.2%; P = .036). An individual component analysis of the primary composite outcome revealed a trend for more frequent strokes (2.3% vs 1.2%; P = .13) and TIAs (0.54% vs 0%; P = .10) in the UE access group. On multivariable analysis, total TF access was associated with a 60% reduction in the frequency of perioperative cerebrovascular events (odds ratio, 0.39; P = .029). No significant differences were observed between UE and TF access in the technical success rate (96.5% vs 96.8%; P = .72), perioperative mortality (2.9% vs 2.6%; P = .72), or local access-related complications (6.5% vs 5.5%; P = .43). CONCLUSIONS In the present large, multicenter, retrospective analysis of prospectively collected data, a total TF approach for F-BEVAR was associated with a lower rate of perioperative cerebrovascular events compared with UE access. Although the cerebrovascular event rate was low with UE access, the TF approach offered a lower risk of stroke and TIA. UE access will continue to play a role for appropriately selected patients requiring more complex repairs with anatomy not amenable to the TF approach.

Fenestrated/branched endovascular aortic repair using unilateral femoral access in patients with iliac occlusive disease. J Vasc Surg 2023; 77:722-730. [PMID: 36372375 DOI: 10.1016/j.jvs.2022.10.049] [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: 05/06/2022] [Revised: 07/01/2022] [Accepted: 10/30/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVE Fenestrated/branched endovascular aortic repair (F/BEVAR) in patients with occluded iliac arteries is challenging owing to limited access for branch vessel catheterization and increased risk for leg and spinal ischemic complications. The aim of this study was to analyze technical strategies and outcomes of F/BEVAR in patients with unilateral iliofemoral occlusive disease. METHODS We performed a retrospective review of all consecutive patients treated by F/BEVAR in two institutions (2003-2021). Patients with unilateral iliofemoral occlusive disease were included in the analysis. All patients had one patent iliac artery that was used for advancement of the fenestrated-branch component. Preloaded catheter/guidewire systems or steerable sheaths were used as adjuncts to facilitate catheterization. Primary endpoints were technical success, mortality, major adverse events (stroke, spinal cord injury, dialysis or decrease in the glomerular filtration rate of more than 50%, bowel ischemia, myocardial infarction, or respiratory failure), primary iliac patency, and freedom from reinterventions. RESULTS There were 959 patients treated with F/BEVAR. Of these, 15 patients (1.56%; mean age, 74 years; 80% male) had occluded iliac arteries and 1 patent iliofemoral access and were treated for a thoracoabdominal aortic aneurysm (n = 8) or juxtarenal abdominal aortic aneurysm (n = 7). Brachial access was used in 14 of the 15 patients and preloaded systems in 7 of the 15 patients (47%). The remaining 53% had staggered deployment of stent grafts. There were seven physician-modified endovascular grafts, seven custom-made devices, and one off-the-shelf device used. Thirteen patients (87%) had distal seal using aortouni-iliac stent grafts and two (13%) had distal seal in the infrarenal aorta. Concomitant femoral crossover bypass (FCB) was performed in two patients and six patients had a prior FCB. Technical success was 100%. There were no intraoperative complications or early lower extremity ischemic complications, and all FCB were preserved. There was one mortality (7%) within 30 days owing to retrograde type A dissection. Major adverse events occurred in 20% of patients. The median follow-up was 12 months (range, 0-85 months). Two patients (13%) required three reinterventions. One patient required proximal stent graft extension for an acute type B dissection (3 months) and another required iliac extension for type Ib endoleak of an aortouni-iliac graft (21 months) and thrombolysis of that extension (50 months). At last follow-up, all patients had primary graft patency except one with secondary graft patency without new claudication. One patient had a single renal artery stent occlusion at follow-up with no r-intervention. The overall survival rate was 60%, without aortic-related deaths. CONCLUSIONS Although challenging, F/BEVAR with unilateral femoral/brachial approach is feasible in patients with occluded iliac limbs, with an important rate of ischemic complications, but satisfactory outcomes.

Abstract
OBJECTIVE To describe the feasibility and outcomes of endovascular repair of distal aortic arch aneurysms using a patient-specific stent graft with a pre-loaded single retrograde left subclavian artery (LSA) branch stent graft. METHODS We reviewed the clinical data and outcomes of consecutive patients enrolled in an ongoing prospective, non-randomized physician-sponsored investigational device exemption study to evaluate the outcomes of endovascular aortic arch repair using patient-specific arch branch stent grafts (William Cook Europe, Bjaeverskov, Denmark) between 2019 and 2022. All patients received a design with triple-wide scallop and a single retrograde LSA branch with a pre-loaded catheter. RESULTS There were five male patients with median age of 77 years old (72-80) treated using the single LSA branch stent graft. Technical success was achieved in all patients. Median operating time, fluoroscopy time, and total radiation dose area product were 103 (78-134) minutes, 26 (19-39) minutes, and 123 (71-270) mGy.cm2, respectively. There were no 30-day or in-hospital mortality, neurological or other major adverse events (MAEs). During median follow-up of 21 (20-27) months, all patients were alive with patent LSA branches, except for one who died of COVID-19 complications. There was no branch instability or secondary interventions. CONCLUSION This early feasibility study demonstrates successful endovascular repair of distal aortic arch aneurysms using a patient-specific stent graft with single retrograde LSA branch without technical failures, mortality or neurological events. Larger clinical experience and longer follow-up are needed to determined effectiveness of this approach in patients who need endovascular repair with proximal extension into Zone 2.

Abstract
Open surgical repair remains the gold standard for treatment for aortic arch diseases, but these operations can be associated with wide heterogeneity in outcomes and significant morbidity and mortality, particularly in elderly patients with severe comorbidities or those who had prior arch procedures via median sternotomy. Endovascular repair has been introduced as a less invasive alternative to reduce morbidity and mortality associated with open surgical repair. The technique evolved with new device designs using up to three inner branches for incorporation of the supra-aortic trunks. This manuscript summarizes technical tips and clinical experience with the triple inner arch branch stent graft for total endovascular repair of aortic arch pathologies.

Abstract
OBJECTIVE There is paucity of data on the durability of physician modified endografts (PMEGs) for complex abdominal (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) despite widespread use. The aim of this study was to evaluate and compare the early and long-term outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) for CAAAs and TAAAs using PMEGs. METHODS We reviewed clinical data and outcomes of patients treated by FB-EVAR using PMEGs for CAAAs (defined as short-neck infrarenal, juxtarenal, and pararenal AAAs) and TAAAs between 2007 and 2019. All patients were treated by a dedicated team with extensive manufactured device experience. Endpoints included 30-day mortality and major adverse events, patient survival and freedom from aortic-related mortality (ARM), freedom from secondary intervention, target artery (TA) patency, and freedom from TA endoleak and TA instability. RESULTS Of 645 patients undergoing FB-EVAR, 156 patients (24%) treated with PMEG (121 males; mean age, 75 ± 8 years) were included. There were 89 CAAAs, 33 extent IV TAAAs and 34 extent I to III TAAAs. A total of 452 renal-mesenteric targets (3.1 ± 1.0 vessels/patient) were incorporated. Patients with TAAAs had significantly (P < .05) larger aneurysms (73 ± 11 vs 68 ± 14 mm), more TAs incorporated (3.4 ± 0.9 vs 2.8 ± 1.0), and more often had previous aortic repair (54% vs 27%). Technical success was higher in patients treated for CAAAs (99% vs 91%; P = .04). Thirty-day and/or in-hospital mortality was 5.7% and was significantly lower for CAAAs compared with TAAAs (2% vs 10%; P = .04), with three of nine early mortalities (33%) among patients treated emergently. After a mean follow-up of 49 ± 38 months, there were 12 aortic-related deaths (7.6%), including nine early deaths (5.7%) from perioperative complications and three late deaths (1.9%) from rupture. At 5 years, patient survival was 41%. Patients treated for CAAAs had higher 5-year freedom from ARM (P = .016), TA instability (P = .05), TA endoleak (P = .01), and TA secondary interventions (P = .05) with a higher, but non-significant, freedom from sac enlargement ≥5 mm (P = .11). Primary and secondary TA patency was 91% ± 2% and 99% ± 1%, respectively. Sac regression ≥5 mm occurred in 67 patients (43%) and was associated with increased survival (hazard ratio, 0.54; 95% confidence interval, 0.37-0.80) compared with those without sac regression. CONCLUSIONS FB-EVAR using PMEGs was performed with acceptable long-term outcomes. Overall patient survival was low due to significant underlying comorbidities. Patients treated for CAAAs had higher freedom from ARM, TA instability, TA endoleak, TA secondary interventions, and a trend towards higher freedom from sac enlargement compared with patients treated for TAAAs. Sac regression was associated with improved patient survival.

Abstract
Thoracic endovascular aortic repair (TEVAR) has been widely accepted as a treatment option in patients with thoracic aortic aneurysms and dissections who have suitable anatomy. It is estimated that up to 60% of patients treated by TEVAR require extension of the repair into the distal aortic arch across Ishimaru zone 2. In these patients, coverage of the left subclavian artery (LSA) without revascularization has been associated with increased risk of arm ischemia, stroke, and spinal cord injury. The Gore Thoracic Branch Endoprosthesis (TBE, WL Gore, Flagstaff, AZ, USA) is the first off-the-shelf thoracic branch stent-graft approved by the Federal Drug Administration for treatment of distal aortic arch lesions requiring extension of the proximal seal into zone 2. This article summarizes the technical pitfalls and clinical outcomes of the TBE® device in zone 2.

Abstract
OBJECTIVE The aim of this study was to compare outcomes of single or multistage approach during fenestrated-branched endovascular aortic repair (FB-EVAR) of extensive thoracoabdominal aortic aneurysms (TAAAs). METHODS We reviewed the clinical data of consecutive patients treated by FB-EVAR for extent I to III TAAAs in 24 centers (2006-2021). All patients received a single brand manufactured patient-specific or off-the-shelf fenestrated-branched stent grafts. Staging strategies included proximal thoracic aortic repair, minimally invasive segmental artery coil embolization, temporary aneurysm sac perfusion and combinations of these techniques. Endpoints were analyzed for elective repair in patients who had a single- or multistage approach before and after propensity score adjustment for baseline differences, including the composite 30-day/in-hospital mortality and/or permanent paraplegia, major adverse event, patient survival, and freedom from aortic-related mortality. RESULTS A total of 1947 patients (65% male; mean age, 71 ± 8 years) underwent FB-EVAR of 155 extent I (10%), 729 extent II (46%), and 713 extent III TAAAs (44%). A single-stage approach was used in 939 patients (48%) and a multistage approach in 1008 patients (52%). A multistage approach was more frequently used in patients undergoing elective compared with non-elective repair (55% vs 35%; P < .001). Staging strategies were proximal thoracic aortic repair in 743 patients (74%), temporary aneurysm sac perfusion in 128 (13%), minimally invasive segmental artery coil embolization in 10 (1%), and combinations in 127 (12%). Among patients undergoing elective repair (n = 1597), the composite endpoint of 30-day/in-hospital mortality and/or permanent paraplegia rate occurred in 14% of single-stage and 6% of multistage approach patients (P < .001). After adjustment with a propensity score, multistage approach was associated with lower rates of 30-day/in-hospital mortality and/or permanent paraplegia (odds ratio, 0.466; 95% confidence interval, 0.271-0.801; P = .006) and higher patient survival at 1 year (86.9±1.3% vs 79.6±1.7%) and 3 years (72.7±2.1% vs 64.2±2.3%; adjusted hazard ratio, 0.714; 95% confidence interval, 0.528-0.966; P = .029), compared with a single stage approach. CONCLUSION Staging elective FB-EVAR of extent I to III TAAAs was associated with decreased risk of mortality and/or permanent paraplegia at 30 days or within hospital stay, and with higher patient survival at 1 and 3 years.

Abstract
OBJECTIVE We compared the outcomes of fenestrated-branched (FB) endovascular abdominal aortic aneurysm repair (EVAR) using low-profile (LP) and standard-profile (SP) stent grafts for the treatment of complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs). METHODS We reviewed the clinical data of 466 consecutive patients (70% male; mean age, 74 ± 8 years) enrolled in a prospective nonrandomized study to investigate FB-EVAR for the treatment of CAAAs and TAAAs (2013-2021). The endpoints compared between the patients treated with LP (18F-20F) and SP (20F-22F) devices included procedural metrics, access-related complications, major adverse events (MAE), patient survival, freedom from secondary intervention, thromboembolic events, stent graft integrity issues, aneurysm sac enlargement, and the rate of sac shrinkage. RESULTS Of the 466 aneurysms treated by FB-EVAR, 138 were CAAAs and 141 were extent IV and 187 extent I to III TAAAs, with a mean number of 3.9 ± 0.5 vessels stented per patient. LP devices had been used in 239 patients (51%) and SP devices in 227 patients (49%). LP devices had been used more frequently for chronic dissections (12% vs 7%; P = .041) and with preloaded systems (77% vs 65%; P = .005) and bilateral percutaneous femoral access (83% vs 74%; P = .020) and less frequently with upper extremity access (67% vs 88%; P < .001) and iliac conduits (2% vs 6%; P = .020). The patients treated using LP devices had experienced similar technical success (96% vs 97%; P = .527), with a shorter total operating time (225 ± 81 minutes vs 243 ± 78 minutes; P = .018), lower radiation exposure (median, 0.93 Gy; interquartile range [IQR], 0.94; vs median, 1.01 Gy; IQR, 0.91 Gy; P < .001), and less use of contrast (median, 135 mL; IQR, 68 mL; vs median, 144 mL; IQR, 80 mL; P = .008). No differences were found in the rates of iliofemoral access complications between the LP and SP device groups (1.3% vs 3.5%; P = .107). At 30 days, 5 patients had died (1%) and MAEs had occurred in 89 patients (19%), with no differences between the two groups. The mean follow-up was 28 months (95% confidence interval, 25-30 months). At 4 years, the patients treated with LP devices had had similar freedom from all-cause mortality (69% ± 6% vs 68% ± 4%; P = .199), freedom from aortic-related mortality (97% ± 1% vs 98% ± 1%; P = .488), freedom from any secondary intervention (65% ± 6% vs 70% ± 4%; P = .433), freedom from thromboembolic events (98% ± 1% vs 99% ± 1%; P = .364) and aneurysm sac enlargement (93% ± 3% vs 91% ± 3%; P = .293). However, the LP group had had less freedom from any integrity-related issues (92% ± 5% vs 100%; P < .001). The cumulative risk of sac shrinkage was greater for patients treated with LP devices (adjusted hazard ratio, 2.040; 95% confidence interval, 1.516-2.744; P < .001). CONCLUSIONS FB-EVAR was performed with low rates of mortality and MAEs, irrespective of the device profile. However, the procedures performed with LP devices had had less need for iliac conduits and had had better procedural metrics. The use of LP devices resulted in higher rates of sac shrinkage. However, the results on stent graft integrity require future investigation.

Abstract
BACKGROUND Hybrid debranching repair of pararenal and thoracoabdominal aortic aneurysms was initially designed as a better alternative to standard open repair, addressing the limitations of endovascular repair involving the visceral aorta. We reviewed the collective outcomes of hybrid debranching repairs using extra-anatomic, open surgical debranching of the renal-mesenteric arteries, followed by endovascular aortic stenting. METHODS Data from patients who underwent hybrid repair in 14 North American institutions during 10 years were retrospectively reviewed. Society of Vascular Surgery scores were used to assess comorbidity risk. Early and late outcomes, including mortality, morbidity, reintervention, and patency were analyzed. RESULTS A total of 208 patients (118 male; mean age, 71±8 years old) were treated by hybrid repair with extraanatomic reconstruction of 657 renal and mesenteric arteries (mean 3.2 vessels/patient). Mean aneurysm diameter was 6.6±1.3 cm. Thoracoabdominal aortic aneurysms were identified in 163 (78%) patients and pararenal aneurysms in 45 (22%). A single-stage repair was performed in 92 (44%) patients. The iliac arteries were the most common source of inflow (n=132; 63%), and most (n=150; 72%) had 3 or more bypasses. There were 30 (14%) early deaths, ranging widely across sites (0%-21%). A Society of Vascular Surgery comorbidity score >15 was the primary predictor of early mortality (P<0.01), whereas mortality was 3% in a score ≤9. Early complications occurred in 140 (73%) patients and included respiratory complications in 45 patients (22%) and spinal cord ischemia in 22 (11%), of whom 10 (45%) fully recovered. At 5 years, survival was 61±5%, primary graft patency was 90±2%, and secondary patency was 93±2%. The most significant predictor of late mortality was renal insufficiency (P<0.0001). CONCLUSIONS Mortality after hybrid repair and visceral debranching is highly variable by center, but strongly affected by preoperative comorbidities and the centers' experience with the technique. With excellent graft patency at 5 years, the outcomes of hybrid repair done at centers of excellence and in carefully selected patients may be comparable (or better) than traditional open or even totally endovascular approaches. However, in patients already considered as high-risk for surgery, it may not offer better outcomes.

Abstract
Patients with complex aortic aneurysms (CAA) are often high risk due to advanced age and widespread atherosclerosis affecting numerous vascular territories. Therefore, a thorough perioperative evaluation is needed prior to performing in any type of aortic repair, regardless of whether an endovascular or open surgical approach is selected. Because these operations are technically demanding and often result in end organ ischemia, it is not surprising that complex aortic repair carries significant risk of morbidity and mortality. Disabling complications such as dialysis, major stroke and paraplegia constitute the main limitation of complex aortic repair. The aim of this article was to review postoperative management to mitigate complications after CAA repair.

Abstract
Intramural hematoma (IMH) is one of the acute aortic syndromes along with acute aortic dissection and penetrating aortic ulcer. The three conditions can occur alone or in combination with overlapping presentation. Medical, open surgical, and endovascular treatment is tailored depending on clinical presentation, timing, and location within the aorta. Among patients who present with acute IMH affecting the ascending aorta (Type A), urgent open surgical repair is considered the primary line of treatment in patients who are suitable candidates and unstable. The management of IMH in the descending aorta and aortic arch (Type B) is similar to that applied to treat acute dissections in the same segment. Medical treatment with sequential imaging is recommended in patients with uncomplicated course, and endovascular repair is indicated in patients with rupture, persistent pain, end-organ ischemia, or rapid aortic enlargement. This review discusses the ideal timing for treatment of IMH.

Abstract
Fenestrated-branched endovascular aortic repair (FB-EVAR) has gained widespread acceptance in patients with complex aortic aneurysms. It has evolved from an alternative to treat elderly and higher risk patients to the first line of treatment in most patients with suitable anatomy, independent of the clinical risk. Currently, these devices are available off-the-shelf (ready to use) and tailored to the patient anatomy with the options of fenestrated, branched and mixed fenestrated, and branched designs. Reports from single and multicenter experiences and systematic reviews have shown lower mortality and morbidity for FB-EVAR compared with historical results of open surgical repair. The main advantages are noted on mortality, respiratory complications, acute kidney injury, and length of hospital stay. The purpose of this article is to review the advances in the endovascular repair of complex aortic aneurysms exploring the indications for treatment, preoperative evaluation, patient selection, device design, and implantation technique.

Abstract
OBJECTIVE In the present study, we assessed the effects of patient frailty status on the early outcomes and late survival after fenestrated-branched endovascular aortic repair (FB-EVAR) for complex abdominal and thoracoabdominal aortic aneurysms. METHODS We retrospectively reviewed the clinical data and outcomes of consecutive patients who had undergone elective FB-EVAR from 2007 to 2019 in a single institution. A previously validated 11-item modified frailty index (mFI-11) was derived from the comorbidity and preoperative functional status data. An mFI-11 <0.3 was defined as low risk, 0.3 to 0.5 as medium risk, and >0.5 as high risk. The studied outcomes were 90-day mortality, major adverse events (MAE), and long-term survival. Multivariate analyses were performed to identify the independent predictors of these outcomes. RESULTS A total of 592 patients (155 women, mean age, 75 ± 8 years) had undergone FB-EVAR. Using the mFI-11, 310 patients (52%) were included in the low-risk, 199 (34%) in the medium-risk, and 83 (14%) in the high-risk group. The 90-day mortality was significantly higher in the high-risk group than in the medium- and low-risk groups (13%, 4%, and 3%, respectively; P < .01). The corresponding MAE rates were 27%, 18%, and 19% (P = .23). As a subgroup, 44 patients in the high-risk group had had chronic kidney disease (CKD). The 90-day mortality for these patients was as high as 23%, and 32% had experienced MAE. On multivariable analysis, the independent risk factors for 90-day mortality were CKD, respiratory disease, and a high mFI-11. The independent risk factors for MAE were female sex, CKD, larger aneurysm diameter, and the high-risk subgroup with CKD. The independent risk factors for long-term mortality were age, a low body mass index, CKD, larger aneurysm diameter, extent I-III thoracoabdominal aortic aneurysm, respiratory disease, congestive heart failure, a history of cerebrovascular problems, and higher mFI-11. The estimated survival at 1 year was 91% ± 2% in the low-risk, 88% ± 2% in the medium-risk, and 78% ± 5% in the high-risk group (P < .001). The corresponding 5-year survival estimates were 60% ± 4%, 52% ± 5%, and 32% ± 6%. The mean follow-up time was 2.9 ± 2.3 years. The patients treated during the first quartile of the study period were significantly more frail than were those in the later quartiles. Also, the outcomes of FB-EVAR had improved over time. CONCLUSIONS Greater frailty was significantly associated with early mortality. Together with CKD, frailty was also associated with MAE and lower patient survival after FB-EVAR. The mFI-11 represents the accumulation of comorbidities and can be used to assist in better patient selection for FB-EVAR.

Abstract
OBJECTIVE To report the outcomes of fenestrated-branched endovascular repair (FBEVAR) for thoracoabdominal aortic pathology after total aortic arch replacement with frozen elephant trunk (TAR+FET). METHODS Interrogation of prospectively-maintained databases from four high volume aortic centres identified consecutive patients treated with distal FBEVAR after prior TAR+FET between August 2013 and September 2020. Primary endpoint was 30-day/in-hospital mortality. Secondary end points were technical success, early clinical success, mid-term survival and freedom from re-intervention. Data are presented as median (IQR). RESULTS 39 patients [21 men; median age, 73 years (67-75)] with degenerative (n=22) and post-dissection TAAAs (n=17) [median diameter 71 mm (61-78)] were identified. Distal FBEVAR was intended in 27 patients [median interval 9.8 months (6.2-16.6)], anticipated in seven and unexpected in five. 31 patients had a two (n=24) or three (n=7) stage distal FBEVAR. Reno-visceral target vessel preservation was 99.3% (145 of 146). Early primary and secondary technical success was 92% and 97%, respectively. 30-day mortality was 2.6% [n=1; respiratory failure and spinal cord ischaemia (SCI)]. Six survivors also developed SCI which was associated with complete (n=4), or partial recovery (n=2) at hospital discharge. No patients required renal replacement therapy or suffered a stroke. Early clinical success was 95%. Median follow-up was 30.5 months (23.7-49.7). Eleven patients required 16 late re-interventions. Estimated 3-year survival and freedom from re-intervention were 84±6% and 63±10%, respectively. CONCLUSIONS Distal FBEVAR after prior TAR+FET is associated with high technical success and low early mortality. The risk of SCI is significant although the majority of patients demonstrate full or partial recovery before hospital discharge. Mid-term patient survival is favourable but there remains a high requirement for late re-intervention. FBEVAR represents an acceptable alternative to distal open TAAA repair.
