Background: Chronic limb threatening lower limb ischaemia (CLTI) gives high limb loss and mortality. Infragenicular
Femoro-popliteal bypass offers in-line flow to target vessels. When vein not available, composite and
prosthetic grafts are used.
Aim of the work: Comparing composite vs synthetic femoro-popliteal bypass conduits in treatment of CLTI.
Patients and methods: 20 adult patients were included in this prospective study from July 2020 to July 2021
having CLTI requiring below knee femoro-popliteal bypass, no suitable vein conduit. Ten had composite grafts
bypass (group A) and 10 patients had synthetic graft (group B), and followed for 6 months.
Results: Improved clinical manifestations in both groups and significant increase of ankle brachial index. 6 months
1ry and 2ry patency were 90% and 100% in group A, and 67% and 78% in group B. Limb salvage were 100% in
group A and 89% in group B. No significant difference between groups' outcome, complications, and ABI.
Conclusion: Both types of conduit showed acceptable feasibility and outcome.
