Abstract
The importance of the vasa vasorum and blood supply to the wall of human saphenous vein (hSV) used for coronary artery bypass grafting (CABG) is briefly discussed. This is in the context of the possible physical link of the vasa vasorum connecting with the lumen of hSV and the anti-ischaemic impact of this microvessel network in the hSV used for CABG.
Highlights
The importance of the vasa vasorum in the performance of human saphenous vein used for coronary artery bypass grafting (CABG) has been highlighted in various publications over the last 15 years[1,2,3,4,5,6,7,8,9]
The vasa vessels, including those located in the adventitia and those associated with the vein’s surrounding pedicle of fat[11], protect the human saphenous vein (hSV) once implanted as grafts during CABG
A prime focus of this mini-review is on the luminal aspect of hSV and a possible link, either via tributaries or by direct contact, with the vein’s rich vasa vasorum system as elegantly presented previously[3,4,12,13]
Summary
The importance of the vasa vasorum in the performance (patency) of human saphenous vein (hSV) used for coronary artery bypass grafting (CABG) has been highlighted in various publications over the last 15 years[1,2,3,4,5,6,7,8,9]. One of the intriguing questions regarding blood supply through the wall of the hSV is whether there are direct openings (terminations) of the vasa vasorum into the vein lumen?
