Yale New Haven Hospital's Brandon A. Creisher, MD, presented "Outcomes of infrainguinal bypass with spliced veins in patients with chronic limb threatening ischemia" at .
Objectives ⬇️
Single segment greater saphenous vein (ssGSV) is the gold standard conduit for infrainguinal bypass in chronic limb-threatening ischemia (CLTI). Spliced vein bypass (SVB) is an alternative conduit, but its outcomes have not been well characterized. Moreover, the impact of the number of spliced segments on outcomes remains unclear. This study examines the outcomes of SVB with 2 vein segments (2sSVB) and 3 vein segments or more (3sSVB) compared to ssGSV for infrainguinal bypass.
Methods ⬇️
The Infrainguinal Bypass Vascular Quality Initiative (VQI) module (2003-2025) was reviewed for patients treated for CLTI with ssGSV, 2sSVB, and 3sSVB. Propensity matching (3:1) was performed to compare 2sSVB (cohort 1) and 3sSVB separately to ssGSV (cohort 2) adjusting for baseline characteristics including indication, urgency, and bypass configuration. Perioperative and long-term outcomes were reported, and the primary outcome was MALE-free survival.
