Randomized trial of endoscopic versus open vein harvest for coronary artery bypass grafting: six month patency rates

Yun KL et all. Objective: We sought to compare the 6-month angiographic patency rates of greater saphenous veins removed during coronary artery bypass grafting with the endoscopic vein harvest or open vein harvest techniques.  

Association between endoscopic versus open vein-graft harvesting and mortality, wound complications, and cardiovascular events in patients undergoing CABG Surgery

Williams JB et all. Objective: To compare the long-term outcomes of endoscopic versus open vein-graft harvesting for Medicare patients undergoing CABG surgery in the United States.

Endoscopically assisted in situ lower extremity bypass graft: a preliminary report of a new minimally invasive technique

Suggs WD, Sanchez LA, et all. Objective: Lower extremity arterial reconstructions with in situ greater saphenous vein (GSV) are an important component of limb salvage surgery. Initially, the procedure was performed through continuous skin incisions for side branch occlusion and valve lysis with a wound complication rate of 5% to 25%. To decrease these complications, endoscopic GSV harvest equipment was used in 25 in situ vein bypass grafts in 25 patients performed over 24 months.

The Society of Thoracic Surgeons 2008 cardiac surgery risk models: part 1—coronary artery bypass grafting surgery

Shahian DM, O’Brien SM, et all. Background: The first version of The Society of Thoracic Surgeons National Adult Cardiac Surgery Database (STS NCD) was developed nearly 2 decades ago. Since its inception, the number of participants has grown dramatically, patient acuity has increased, and overall outcomes have consistently improved. To adjust for these and other changes, all STS risk models have undergone periodic revisions. This report provides a detailed description of the 2008 STS risk model for coronary artery bypass grafting surgery (CABG). 

Heparin administration prior to endoscopic vein harvest limits clot retention and improves graft patency

Poston R, Desai P et all. Objective: Residual clot strands within the saphenous vein (SV) is an increasingly recognized sequela of endoscopic vein harvest (EVH). CO2 insufflation, used to facilitate visualization, causes stagnation of blood within the SV yet anticoagulation is not usually given until after harvest. We hypothesized that heparinization prior to CO2 insufflation would reduce the severity of this residual clot and improve graft patency.
