Femoral vein transposition fistula with short skip incisions: an optimised minimally invasive technique.

Abstract

ObjectivesFemoral vein transposition (tFV) is a complex procedure that provides high patency rates for patients with exhausted upper-limb vascular access. Traditionally, the procedure involves a long single incision in the thigh to harvest the femoral vein, but this approach is associated with increased risks of local complications such as infections and haematomas. Skip incisions have shown to lower complication rates and shorten maturation times. We present an optimised, minimally invasive technique that transposes the femoral vein through three short skip incisions on the anterior thigh.MethodsWe present the technical details and outcomes of three patients who underwent femoral vein transposition (tFV) for haemodialysis access. Additionally, we conducted a literature review on lower-limb vascular access options for haemodialysis.ResultsPre-operative clinical and ultrasound assessments confirmed femoral vein transposition (tFV) eligibility. The procedure involved three short skip incisions along the medial thigh to harvest the femoral vein. Subcutaneous tunnelization was performed through the anterior thigh. The arteriovenous anastomosis was sized at 3-4 mm to minimise the risk of lower-limb steal syndrome. The average procedure duration was 120 min. Postoperative recovery was uneventful, with patients discharged an average of 6 days after surgery. Wound healing was satisfactory, and the access was cannulated approximately 3 weeks post-procedure.ConclusionsThis method reduces wound complications and significantly improves the comfort of patients and dialysis nursing staff by enhancing cannulation access and increasing the availability of puncture sites, thereby improving the overall patient care experience.
