How I do it: Endoscope-assisted in situ arterial reconstruction of the lower limb.

Arterial reconstruction with the great saphenous vein is a frequently performed vascular surgery technique for revascularization of chronic limb threatening ischemia. Surgeon variations of the procedure are common and aim to balance patency, limb salvage, complications, hospital resources, and technical feasibility. We describe a minimally invasive revascularization option using endoscope assistance for in situ great saphenous vein-arterial bypass to treat infrainguinal occlusive disease. We highlight patient selection, operating room setup, instrument details, and procedure strategies that facilitate the use of this technique. The development and refinement of minimally invasive techniques for lower extremity arterial bypass are critical to reduce wound complications and improve limb salvage outcomes in patients.
