Approximately 40–50% of patients undergoing thoracic endovascular aortic repair require left subclavian artery coverage for adequate proximal landing zone. Many of these patients undergo left subclavian artery revascularisation. However, outcomes data for left subclavian artery revascularisation in the context of thoracic endovascular aortic repair remain limited. In this study, 70 left subclavian artery revascularisation procedures, performed on thoracic endovascular aortic repair patients at a tertiary hospital, were retrospectively reviewed. Particular emphasis was placed on revascularisation-related outcomes during staging interval between revascularisation and thoracic endovascular aortic repair. Forty-six (66%) carotid-subclavian bypass, 17 (24%) carotid-carotid-subclavian bypass and 7 (10%) aorto-inominate-carotid-subclavian bypass procedures were performed. There were no strokes or mortalities following left subclavian artery revascularisation procedures alone. Three (10%) minor complications occurred including a seroma, a haematoma and a temporary neuropraxia. Separation of complications following left subclavian artery revascularisation from those of the associated thoracic endovascular aortic repair can be difficult. Early outcomes data from patients who underwent left subclavian artery revascularisation in isolation indicate that the procedure is safe with low complication rates.

Objectives To summarize the experience and midterm outcomes of physician-modified endovascular grafts for zone 2 thoracic endovascular aortic repair. Methods A retrospective analysis was conducted of 51 consecutive patients (mean age 57.6 ± 12.5 years, 39 males) treated with thoracic endovascular aortic repair using physician-modified endovascular grafts for reconstructing the left subclavian artery from November 2015 to December 2019. The primary endpoints during follow-up were the overall mortality, aorta-related mortality, and major complications. The secondary endpoints were reintervention and the patency of the target branches, the demographics and technical details were also described and analyzed. Results Sixty-three thoracic stent-grafts were deployed in 51 patients and emergency surgery was performed in 10 patients (19.6%). Technical success was 94.1% (48/51). The incidence of perioperative complications was 15.7%, and the 30-day mortality was 0%. At a mean follow-up of 42.0 ± 14.4 months (range, 14–63 months), all the left subclavian arteries remained patent. All-cause mortality was 3.9% (2/51) and not aorta-related deaths. Estimated survival at one and three years was 98.0 ± 1.9% and 96.0 ± 2.8%, respectively. Conclusions The physician-modified endovascular grafts is feasible and effective to preserve left subclavian artery in thoracic endovascular aortic repair for aortic arch pathologies with unhealthy proximal landing zone.

Purpose: To evaluate the perioperative stroke incidence following thoracic endovascular aortic repair (TEVAR) with differing left subclavian artery (LSA) coverage and revascularization approaches in a real-world setting of a nationwide clinical registry. Materials and Methods: The National Surgical Quality Improvement Program registry was interrogated from 2005 to 2017 to identify all nonemergent TEVAR and/or open LSA revascularization procedures. In this time frame, 2346 TEVAR cases met the selection criteria for analysis. The 30-day stroke incidence was compared between patients undergoing TEVAR with (n=888) vs without (n=1458) LSA coverage, for those with (n=228) vs without (n=660) concomitant LSA revascularization among those with coverage, and following isolated LSA revascularization for occlusive disease (n=768). Multivariable logistic regression was employed for risk-adjusted analyses and to identify factors associated with stroke following TEVAR. Results of the regression analyses are presented as the adjusted odds ratio (OR) with 95% confidence interval (CI). Results: The stroke incidence was 2.3% following TEVAR without vs 5.2% with LSA coverage (p<0.001). In TEVARs with LSA coverage, the stroke incidence was 7.5% when the LSA was concomitantly revascularized and 4.4% without concomitant revascularization, while stroke occurred in 0.5% of isolated LSA revascularizations. Of 33 TEVAR patients experiencing a perioperative stroke, 8 (24%) died within 30 days. LSA coverage was associated with stroke both with concomitant revascularization (OR 4.0, 95% CI 2.2 to 7.5, p<0.001) and without concomitant revascularization (OR 2.2, 95% CI 1.3 to 3.8, p=0.002). Other preoperative factors associated with stroke were dyspnea (OR 1.8, 95% CI 1.1 to 3.0, p=0.014), renal dysfunction (OR 2.2, 95% CI 1.0 to 3.8, p=0.049), and international normalized ratio ≥2.0 (OR 3.6, 95% CI 1.0 to 13, p=0.045). Conclusion: Stroke following TEVAR with LSA coverage occurs frequently in the real-world setting, and concurrent LSA revascularization was not associated with a lower stroke incidence.
