No results posted yet for this study

Summary

There is no shared vision relating to integrity and quality of the conduit after the impact on the vein wall during vein harvesting. In this connection, the investigators studied the initial state of the venous conduit, interoperation damages of the vein and postoperative wound complications while using two methods of GSV harvesting.

Conditions

  • Autovenous Conduit for Coronary Artery Bypass Grafting

Interventions

PROCEDURE

Open vein harvesting

Open vein harvesting was performed as a continuous incision under vision control. The GSV was identified two fingers proximal to the medial malleolus according to the standard practice. The vein was harvested using Metzenbaum scissors, and a continuous incision was made along the route of the vein. Care was taken not to traumatize the nerve, vein or its branches. Vein branches were ligated with titanium clips. The wound was closed in layers with continuous 2-0 Polysorb sutures and 3-0 skin sutures.

PROCEDURE

Endoscopic vein harvesting

Endoscopic vein harvesting was performed through minimal incisions with use of Vasoview 6 system (Maquet Medical Systems, Wayne, NJ, USA.) The vein was identified through a 3 cm incision below the knee. The incision site was sealed using a balloon port to create a tunnel inside the leg. A second unit with cautery was inserted via the port to cut and seal the tributary branches. A 1 cm skin incision was made near the groin to ligate the distal end of the GSV and remove the vein, which was checked for leakage. The wound was closed with 3-0 skin sutures
