Techniques and Outcomes of the No-Touch Vein Conduit as a Y-Composite Graft

Abstract

Although the saphenous vein is a widely used conduit for coronary artery bypass grafting, revascularization using the saphenous vein as an aortocoronary bypass graft has shown disadvantages of lower long-term graft patency rates and subsequently worse clinical outcomes, compared with revascularization using the internal thoracic artery. Of the various efforts to overcome the limitations of vein conduit that are resulting from structural and functional differences from arterial conduit, recent technical improvement in no-touch vein composite graft construction and outcomes of revascularization using no-touch vein composite grafts based on the left internal thoracic artery will be discussed in this topic.

Infection of Vascular Prostheses: A Comprehensive Review

“…The graft is anchored in place by a balloon-expandable or self-expanding metal frame that supports all or part of the graft and provides a tight seal proximal and distal to the diseased segment of the artery. Since it circumvents the need for laparotomy, the crossclamping of the artery, and the obligatory blood loss associated with the opening of the aneurysm sac, the technique has been shown to reduce the morbidity and mortality associated with conventional surgery, and it expands the patient pool to include patients with severe medical-and co-morbidities who were previously denied treatment [11][12][13][14][15][16][17][18][19][20][21][22]. According to the location of implantation, grafts may be extra-cavitary (groins and lower limbs) and intra-cavitary (abdominal or thoracic aorta) [21,22].…”
