[Long-term results of femoro-tibial reconstructions]

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Surgical Outcomes

Background:

• Femoro-tibial bypass surgery is a critical intervention for peripheral artery disease.
• Complications and long-term patency remain significant challenges in femoro-tibial bypass procedures.
• Evaluating different surgical techniques and adjunct procedures is essential for improving patient outcomes.

Purpose of the Study:

• To analyze the outcomes of 136 femoro-tibial bypasses in 127 patients.
• To compare the efficacy of the "in situ" surgical technique for femoro-tibial autovenous bypasses.
• To assess the impact of combining femoro-tibial bypass with lumbar sympathectomy and arterio-venous fistula on long-term function.

Main Methods:

• Retrospective analysis of 136 femoro-tibial bypass surgeries in 127 patients.
• Evaluation of complication rates, including lethal outcomes and shunt thrombosis.
• Assessment of bypass patency, specifically for the "in situ" autovenous technique.
• Analysis of combined procedures involving lumbar sympathectomy and arterio-venous fistula creation.

Main Results:

• Overall complication rates included a 1.5% lethal outcome (myocardial infarction) and 10.3% shunt thrombosis.
• The "in situ" technique demonstrated superior patency rates for femoro-tibial autovenous bypasses at 68.7%.
• Combination therapy (femoro-tibial bypass with lumbar sympathectomy and arterio-venous fistula) showed improved long-term bypass function.

Conclusions:

• The "in situ" technique is associated with the best patency for femoro-tibial autovenous bypasses.
• Adjunctive procedures like lumbar sympathectomy and arterio-venous fistula creation can enhance long-term bypass performance.
• Careful patient selection and surgical technique are crucial for minimizing complications and optimizing results in femoro-tibial bypass surgery.
