A Multicenter Study of the Mid-term Outcomes of Patients with Uncomplicated Type B Aortic Dissection After Distal Porous Talos Stent-Graft Implantation. Ann Vasc Surg 2024; 104:315-323. [PMID: 38599492 DOI: 10.1016/j.avsg.2024.02.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 01/19/2024] [Accepted: 02/18/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND The Talos stent-graft has extended length to improve aortic remodeling, and distal porous design to decrease the rate of spinal cord ischemia (SCI). This study retrospectively analyzed its mid-term outcomes for uncomplicated type B aortic dissection in a multicenter study. METHODS The primary safety end point was 30-day major adverse events, including all-cause mortality, dissection-related mortality, conversion to open surgery, and device-related adverse events. The primary efficacy end point was treatment success at 12 months postoperation, defined as no technical failure or secondary dissection-related reintervention. The survival status of the patients was visualized using the Kaplan-Meier curve. Aortic growth was assessed at 4 levels, and SCI was evaluated at 12 months. RESULTS 113 patients participated with a mean age of 54.4 (11.1) years and 71.7% (81/113) were male. The 30-day mortality was 0.9% (1/113), no conversions to open surgery or device-related adverse events were recorded. The 12-month treatment success rate was 99.1% (112/113), with no dissection-related reinterventions. There was no spinal cord or visceral ischemia at 12 months. At a median of 34 months follow-up, 9 further deaths were recorded and the 3-year survival rate was 91.7%. The percentage of aortic growth was 1.8% (2/111) at the tracheal bifurcation, 3.6% (4/111) below the left atrium, 6.0% (5/83) above the celiac artery, and 12.1% (9/74) below the lower renal artery. The total thrombosis rate of the false lumen at the stented segment was 80.5% (91/113). CONCLUSIONS The results showed satisfactory results of Talos stent-graft in terms of safety and efficacy. More data are needed to confirm the long-term performance.

Entry Site Is Associated With Aortic Enlargement After Pre-emptive Endovascular Repair for Uncomplicated Type B Aortic Dissection. J Endovasc Ther 2023:15266028231161224.

Abstract
OBJECTIVES We aimed to examine the mid-term results corresponding to the entry site in patients who underwent pre-emptive thoracic endovascular aortic aneurysm repair (TEVAR) for uncomplicated type B aortic dissection (TBAD). METHODS We included 27 patients who underwent pre-emptive TEVAR for uncomplicated TBAD between September 2014 and December 2019. We divided the patients into 2 groups depending on the proximal landing zone (zone 2 group, zone ≥3 group) and retrospectively analyzed the risk of all-cause and aorta-related mortality, aortic events (rupture, open conversion, and secondary intervention), and aortic enlargement (≥5 mm). RESULTS The median age of the patients was 53 (47-65) years. The median duration from the onset of uncomplicated TBAD to TEVAR was 43 (30-99) days, and the median follow-up duration was 48 (36-57) months. The maximum preoperative diameter of the dissected aorta was 40 mm in the zone 2 group and 35 mm in the zone ≥3 group (p=0.134). There was no case of hospital death or spinal cord ischemia; however, there was 1 (3.7%) case of perioperative stroke in the zone 2 group. Multivariate analysis of the risk factors for aortic enlargement following pre-emptive TEVAR for uncomplicated TBAD revealed that only zone 2 landing was an independent risk factor. The estimated Kaplan-Meier curve showed a higher rate of aortic enlargement in the zone 2 group at 4 years after pre-emptive TEVAR (46.4% vs 0%, log-rank test; p=0.011). CONCLUSIONS In this study on TBAD, we found that zone 2 landing was associated with aortic enlargement after pre-emptive TEVAR. In cases where the distance from the left subclavian artery to a major entry point was short, there were more cases of aortic dilatation. CLINICAL IMPACT The effectiveness of entry closure for type B aortic dissection was demonstrated in the INSTEAD XL trial. The cause of aortic enlargement after pre-emptive endovascular treatment for type B aortic dissection remains controversial. In the present study, zone 2 landing was a risk factor for aortic enlargement after pre-emptive thoracic endovascular aortic aneurysm repair (TEVAR) for uncomplicated type B dissection. Patients with zone 2 landing should be closely followed up after pre-emptive TEVAR.

Abstract
OBJECTIVE To compare the early and midterm outcomes of three different strategies for an isolated left vertebral artery on the arch (LVoA) revascularisation during thoracic endovascular aortic repair (TEVAR) with a proximal zone 2 landing. METHODS Between January 2016 and December 2021, 67 patients with LVoA and aortic arch pathologies who underwent zone 2 landing TEVAR at four medical centres were enrolled. These patients were divided into three groups for comparison: the novel chimney (group A, n = 28) with the right brachial-left brachial through and through (RLT) procedure; in vitro fenestration (group B, n = 24); and transposition (group C, n = 15). The flow direction and velocity of the LVoA was examined by Doppler ultrasound in the pre-, intra-, and post-operative periods. Primary outcomes were all cause mortality and new neurological symptoms. RESULTS No deaths or new neurological symptoms occurred within 30 days. Early type Ia endoleak rates were 18% (n = 5), 17% (n = 4), and 0% in groups A, B, and C, respectively (p = .22). All patients had antegrade flow of the LVoA. The mean ± standard deviation duration of follow up was 63.6 ± 4.0 months. No deaths were observed during follow up. The rates of new neurological symptoms were 0%, 8%, and 33% in groups A, B, and C, respectively. The rates of midterm type Ia endoleak were 7%, 12%, and 0% in groups A, B, and C, respectively (p = .35). Bidirectional flow rates in the LVoA were 0%, 21%, and 27% in groups A, B, and C, respectively (p = .021). Two (8%) and three (20%) patients in groups B and C underwent a secondary procedure because of mild dizziness, but this was not necessary in group A (p = .058). CONCLUSION The novel chimney technique of the RLT procedure may be feasible for patients with a LVoA requiring zone 2 anchoring. Accurate determination of the safety and feasibility of this novel technique requires larger sample sizes and longer follow up.

Front Cardiovasc Med 2023; 10:1100075. [PMID: 37025689 PMCID: PMC10071004 DOI: 10.3389/fcvm.2023.1100075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 02/28/2023] [Indexed: 04/08/2023] Open
Abstract
Purpose The objective of this research was to investigate whether seasonal variations influence the outcomes of type B aortic dissection (TBAD) patients with thoracic endovascular aortic repair (TEVAR). Patients and methods From 2003 to 2020, a retrospective cohort study was performed, which included 1,123 TBAD patients who received TEVAR. Medical records were used to gather data on baseline characteristics. Outcomes including all-cause mortality and aortic-related adverse events (ARAEs) were tracked and analyzed. Results Of the 1,123 TBAD patients in this study, 308 received TEVAR in spring (27.4%), 240 cases in summer (21.4%), 260 cases in autumn (23.2%), and 315 cases in winter (28.0%). Patients in the autumn group had a significantly lower risk of 1-year mortality than those in the spring group (hazard ratio: 2.66, 95% confidence interval: 1.06-6.67, p = 0.037). Kaplan-Meier curves revealed that patients who underwent TEVAR in autumn had a lower risk of 30-day ARAEs (p = 0.049) and 1-year mortality (p = 0.03) than those in spring. Conclusion This study confirmed that TEVAR operated in autumn for TBAD was associated with a lower risk of 30-day ARAEs and 1-year mortality than in spring.

Single-branched stent-graft with on-table fenestration for endovascular repair of primary retrograde type A aortic dissection: A multicenter retrospective study. Front Cardiovasc Med 2022; 9:1034654. [DOI: 10.3389/fcvm.2022.1034654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 11/03/2022] [Indexed: 11/18/2022] Open
Abstract
ObjectiveThis study aims to evaluate the feasibility, efficacy, and safety of a single-branched stent-graft with on-table fenestration for primary retrograde type A aortic dissection (RTAD) during thoracic endovascular aortic repair (TEVAR).Materials and methodsFrom January 2019 to December 2021, 36 patients with primary RTAD from five tertiary hospitals received medical management in the acute phase. They underwent TEVAR with a proximal zone 1 landing for aortic arch reconstruction in the subacute phase, using a fenestration technique on a single-branched stent-graft. Nearly 2 weeks after admission, computed tomography angiography (CTA) was re-examined to evaluate the thrombosis status of retrograde false lumen (FL). The primary outcomes were technical success, patency of the target branch arteries, and absence of type Ia endoleaks. The second outcomes were stent-graft-related complications and all-cause mortality.ResultsThe mean age was 56.2 ± 11.3 years, and 29 (80.6%) were male. After a median interval of 18.0 [interquartile range (IQR), 17.0–20.3] days of medical treatment, the partial and complete thrombosis of proximal FL rates increased to 52.8% and 47.2%, respectively. One patient (2.8%) experienced postoperative type Ia endoleaks, and was successfully re-treated using coli and Onyx glue. The median hospital stay was 20.5 (IQR, 18.0–23.0) days. The overall technical success rate was 100%. The median follow-up time was 31.5 (IQR, 29.8–34.0) months. There was one death (2.8%) due to gastrointestinal bleeding. Distal aortic segmental enlargement (DASE) occurred in two (5.6%) patients. No major complications or recurrent dissections in the proximal landing zone were recorded during follow up.ConclusionThe retrograde FL in primary RTAD could realize partial or complete thrombosis after medical management in the acute phase, and it might be regarded as a valid proximal landing zone for endovascular repair. The single-branched stent graft with on-table fenestration performed in the subacute phase may be feasible strategy in selective primary RTAD patients.

Front Surg 2022; 9:789954. [PMID: 35747434 PMCID: PMC9209658 DOI: 10.3389/fsurg.2022.789954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 05/03/2022] [Indexed: 11/24/2022] Open
Abstract
Background There is a lack of evidence about the predictive role of serum cardiac troponin I (cTnI) on the long-term adverse outcomes of acute type B aortic dissection (aTBAD) patients after thoracic endovascular aortic repair (TEVAR). In this study, we identified whether cTnI was an independent risk factor of 5-year adverse outcomes for aTBAD patients after TEVAR. Methods We reviewed consecutive aTBAD patients without previous heart disease who were admitted for TEVAR. The total study population was divided into the cTnI(+) group (≥0.03 ng/mL) and the cTnI(−) group (<0.03 ng/mL) according to the time-dependent receiver operating characteristic curve analysis. The differences in clinical characteristics, operative details and clinical outcomes were compared between the two groups. Results There was no difference in age and male prevalence between the two groups. Compared with the cTnI(−) group, the incidence of chronic kidney disease was higher in patients with cTnI ≥0.03 ng/mL. In addition, the cTnI(+) group presented with more frequent premature beats and non-myocardial-infarction ST-T segment changes. In terms of laboratory examinations, white blood cell counts, neutrophil counts, serum D-dimer and serum fibrin degradation products showed an increase in the cTnI(+) group, while lymphocyte and platelet counts showed a decrease in these patients. Patients with elevated cTnI suffered from increased risks of 5-year aortic-related adverse events (hazard ratio, HR = 1.822, 95% confidence interval, CI: 1.094–3.035; p = 0.021) and all-cause mortality (HR = 4.009, 95% CI: 2.175–7.388; p < 0.001). Conclusion Among aTBAD patients without previous heart disease, preoperative elevated cTnI identified patients at an increased risk of long-term adverse outcomes after TEVAR.
