Purpose: This study aimed to (1) evaluate the outcomes of below-knee prosthetic bypass (BKPB) in the absence of the great saphenous vein, and (2) identify risk factors associated with these outcomes. Materials and Methods: This study included 37 consecutive patients who underwent BKPB with or without distal modification between 2010 and 2022. We further assessed the following treatment outcomes: primary patency (PP), secondary patency (SP), limb salvage (LS), and amputation-free survival (AFS) rates. The risk factors for PP were also examined. Results: Most patients (n=31) were male. In 32 (86.5%) patients, BKPBs were performed for chronic limb-threatening ischemia. At the time of initial admission, two (5.4%) early deaths and three (8.1%) major amputations were noted. At 1 year after BKPB, the overall PP, SP, LS, and AFS rates were 78%, 85%, 85%, and 70%, respectively; at 3 years, they were 58%, 70%, 80%, and 52%, respectively; and at 5 years, they were 35%, 58%, 62%, and 29%, respectively. Notably, PP was significantly lower in limbs with ≤1 patent tibial arteries than in limbs with ≥2 patent artery (hazard ratio [HR], 3.80; 95% confidence interval [CI], 1.14-12.69 for overall; and HR, 12.97; 95% CI, 2.15-78.08 for distal anastomosis to below-knee popliteal artery). However, the PP was unaffected by the distal modification. Conclusion: BKPB is a viable option for LS in patients with extensive femoropopliteal disease. Tibial runoff was significantly correlated with patency; therefore, decision-making for BKPB and follow-up must involve careful evaluation of the outflow arteries.
