Results of the tibioperoneal trunk repair in patients with advanced atherosclerosis
Abstract
Objective: To study immediate and long-term results of the tibioperoneal trunk repair (plastic reconstruction or prosthetic repair) during femoropopliteal bypass.Materials and methods: In our retrospective cohort study we analyzed surgical treatment results of 109 patients with lower extremities atherosclerosis who were treated in the Vascular Surgery Unit of Interregional Clinical Diagnostic Center (Kazan, Russian Federation) from 2018 to 2020. 26 (23.8%) patients were hospitalized for stage IB-IIA acute arterial insufficiency with atherothrombosis, and 83 (76.1%) patients were admitted with critical limb ischemia (CLI) as a result of advanced atherosclerosis. Among the CLI patients, 43 (39.4%) of them had stage III chronic arterial insufficiency, and 40 (36.7%) patients had stage IV chronic arterial insufficiency. The study selection criteria included extensive femoral and popliteal arteries disease and significant stenosis or occlusion of the tibioperoneal trunk. TASC II type C lesions were detected in 2 (1.8%) patients, while 107 (98.2%) patients were diagnosed with TASC II type D lesions. Based on the GLASS classification, all 109 (100%) patients had FP grade 3-4 femoropopliteal lesions with concomitant IP grade 1-4 tibial lesion. The main group included 24 (22%) patients who underwent femoropopliteal bypass with plastic or prosthetic repair of the tibioperoneal trunk using an original technique. The control group included 85 (78%) patients who underwent bypass surgery without the tibioperoneal trunk repair. Isolated femorotibial bypass was performed in 7 (8.2%) patients, and 78 (91.7%) patients underwent femoropopliteal bypass with a reversed autogenous vein.Results: We followed up patients for 2 years after surgery. Immediate technical success was 97.24% (106/109). Graft thrombosis was reported in 3 cases. No difference between the groups was observed. Long-term graft patency was significantly higher in the main group (P = .044) and significantly associated with age (RR = 0.96; 95% CI of 0.92 to 1.00, P = .03), type 2 diabetes mellitus (RR = 2.10; 95% CI of 1.10 to 4.10, P = .03), and history of the tibioperoneal trunk repair (RR = 0.43; 95% CI of 0.18 to 1.00, P = .06). Variables associated with patency in the univariate regression at a significance level P ≤ .1 were included in a multivariate model that demonstrated the combined effect of predictors on the outcome.Conclusions: Femoropopliteal bypass with the tibioperoneal trunk repair improves treatment results in patients with extensive peripheral artery disease and immediately threatened limbs or a threat to a limb within 2 years.
