Abstract
The saphenous venous graft used for coronary artery bypass grafting (CABG) procedures is traditionally harvested by means of the open technique, and as a consequence, lower limb wound complications are an important source of morbidity after CABG. Complications such as hematoma, dehiscence, skin necrosis, or wound infection increase the length of stay and delay rehabilitation, ambulation, and exercise training.
With The saphenous vein harvest being such a critical part of this operation, it deserves greater attention in order to reduce morbidity from this component of the operation.
Minimally invasive techniques have been developed in order to reduce the significant morbidity associated with the extensive incisions made during a traditional approach to vein harvest.
Minimally invasive endoscopic saphenous vein harvesting was introduced by Lumsden in 1995. Since that, it has been increasingly investigated in order to reduce the morbidity associated with conventional open vein harvesting, which requires long incisions, and thus postoperative leg wound complications, pain and patient dissatisfaction.
This study was done on 100 patients with multivessel ischemic heart disease undergoing CABG operation more than one graft to compare the outcomes of the two techniques of saphenous vein graft harvesting which are endoscopic vein harvesting (EVH) and open vein harvesting (OVH) techniques. The 100 patients were divided into 2 groups according to the method of saphenous vein harvesting whether it was endoscopic EVH or traditional open OVH. Each group consisted of 50 patients.
