[Effectiveness of femoro-femoral crossover bypass in patients with critical limb ischemia: a retrospective clinical analysis].

AIM: To evaluate the effectiveness of femoro-femoral crossover bypass in high-risk patients with unilateral aorto-iliac occlusive disease.

MATERIAL AND

METHODS

A retrospective analysis was conducted on 26 patients (22 men, 4 women; mean age 67.8±7.4 years) who underwent femoro-femoral crossover bypass using a ring-reinforced PTFE graft at the National Scientific Center of Surgery named after A.N. Syzganovbetween 2017 and 2025. Graft patency, postoperative complications, mortality, and limb salvage were assessed during early and long-term follow-up.

RESULTS

All operations were technically successful with restoration of distal blood flow in 100% of cases. Postoperative complications occurred in 2 patients (7.6%): one late graft infection and one in-hospital death (3.8%). The mean hospital stay was 14±5 days. At five-year follow-up (available in 9 patients), graft patency remained 100%, with complete limb salvage and no major reinterventions.

CONCLUSION

Femoro-femoral crossover bypass is a safe and reliable revascularization method for patients with aorto-iliac occlusive disease who are unsuitable for direct aortic reconstruction. The procedure provides excellent long-term patency, full limb salvage, and minimal morbidity and mortality.
