Abstrakt:	Background: Thoracofemoral bypass has been applied mostly secondary to previous procedures in the treatment of aortoiliac occlusive disease. However, its application as an initial treatment is less common, and long-term outcomes remain uncertain. The aim of this analysis was to review the 16-year experience and long-term outcomes of 31 consecutive patients who underwent thoracofemoral bypass as the primary procedure. Methods: All patients who underwent thoracofemoral bypass for severe aortoiliac occlusive disease between 2005 and 2021 were retrospectively analyzed. The occlusion and calcified plaques of the abdominal aorta at the renal level were common characteristics of all patients. The patients were divided into 2 groups: severe claudication group (Rutherford III group) and chronic limb-threatening ischemia group (Rutherford IV-V). Chi-square test or Fisher's exact test was used to compare categorical variables between the groups, and t-test or Mann-Whitney U-tests were used to compare continuous variables according to their distributions. The Kaplan-Meier curve was used to depict the time-to-event data. Results: Thirty-one patients [age: 62 (56-67.5); male: 87%] underwent thoracofemoral bypass. Among the 31 patients, 21 (67.7%) belonged to the severe claudication group (Rutherford III), while 10 (32.3%) were in the chronic limb-threatening ischemia (Rutherford IV-V). Twenty-two patients (83.8%) remained asymptomatic after thoracofemoral bypass. The mean follow-up duration was 79 ± 32 months. The 30-day mortality rate was 3.2% (n = 1). Major complications were observed in 9.6% of patients (n = 3; respiratory: 6.4%, retroperitoneal hematoma: 3.2%). No significant difference was found between the claudication and chronic limb-threatening ischemia groups regarding major complications (3.2% vs. 6.4%, P = NS). Minor complications occurred in 41.9% of patients, including pleural effusion 9.6% (n = 3), acute kidney injury 9.6% (n = 3), gastrointestinal bleeding 3.2% (n = 1), paralytic ileus 6.4% (n = 2), and superficial skin infection 12.9% (n = 4). The rate of postoperative superficial skin infection was higher in the chronic limb-threatening ischemia group compared to the claudication group (4 [40%] vs. 0 [0%], P: 0.007). The univariable Cox regression analysis revealed that hypertension and diabetes mellitus were not related to primary patency of the thoracofemoral bypass graft. The 5-year Kaplan-Meier estimated primary patency for the entire study was 96% ± 7% (95% confidence interval [CI]: 88.6-100), and the secondary patency was 96.3% ± 6% (95% CI: 89.4-100). The 5-year Kaplan-Meier estimated survival rate after thoracofemoral bypass was 93.4% ± 3 (95% CI: 91-100). Conclusions: We demonstrated in this study that thoracofemoral bypass can yield good outcomes when preferred as the initial treatment in selected patients with juxtarenal total aortic occlusion. Despite being a complex surgical technique, thoracofemoral bypass has shown to have safe, acceptable mortality and morbidity rates, as well as excellent long-term follow-up results in selected patients.
