STUDY: Extent of Thermal Injury in Vascular Conduits Using VirtuoSaph™ Endoscopic Vein Harvesting System in Swine
A. Rojas, MD, et al, University of Michigan, tested the Virtuosaph System in swine model using open technique on arteries and veins to assess extent of thermal spread during branch ligation
ABSTRACT: Randomized Trial of Endoscopic Versus Open Vein Harvest for Coronary Artery Bypass Grafting: Six Month Patency Rates. Journal of Thoracic and Cardiovascular Surgery 2005;129:496-503. Yun, K et al.
This 200-patient study concluded that EVH reduces leg wound complications as compared to open technique without compromising the 6-month patency rate.
ABSTRACT: Strategies to Reduce Intraluminal Clot Formation in Endoscopically Harvested Saphenous Veins. J Thoracic Cardiovasc Surg. 2007; 134:1259-1265. Brown, E. et al.
In this 40-patient study, intraluminal saphenous vein clot formation was compared between endoscopic vein harvesting systems. Results indicate that systemic heparanization and an open system can lessen this complication.
ABSTRACT: Carbon Dioxide Embolism During Endoscopic Saphenous Vein Harvesting in Coronary Artery Bypass Surgery. J Thorac Cardiovasc Surg. 2003; 126:2011-2015. Lin, T et al.
In this 403-patient study, the incidence of significant CO2 embolism during EVH with CO2 insufflation procedures was more than 4% and that continuous monitoring was essential in early detection.
ABSTRACT: Review of Efforts to Decrease Costly Leg Wound Complications in the Medicare Population Following Coronary Revascularization. Heart Surgery Forum 2003;6(4):258-263. Brandt, C et al.
In this retrospective study of 1,909 Medicare patients, a general trend is noted for EVH to have a lower treatment cost per patient than open technique.
ABSTRACT: Financial Impact of Endoscopic Vein Harvest for Infrainguinal Bypass. Journal of Vascular Surgery 2003;37:323-330. Illig, K et al.
In this study with 242 patients, EVH was found to result in cost savings per procedure as compared to use of the open technique.
ABSTRACT: The Transition From Open to Endoscopic Saphenous Vein Harvesting and its Clinical Impact; Texas Heart Institute Journal 2006;33:316-320. Lai, T et al.
This retrospective study of 1,573 procedures concluded that EVH reduces leg wound infections, is safe and reliable, and should be the standard of care for CABG procedures.
