Arterial grafting with the telescoping anastomotic technique for arterial defects.
An arterial graft was taken from the left femoral artery of the rat and grafted into the right femoral artery using the telescoping anastomotic technique at both the proximal and distal anastomoses to compare the patency rate with that of the vein grafts interposed into the arterial defect with the same telescoping technique. The time required for each anastomosis was about 10 minutes and all of the 31 grafts remained patent without application of xylocaine, yielding a higher patency rate than the vein grafts interposed in an arterial defect. The telescoping technique proved to be so dependable that it could be used at least twice in an artery. Inserting one vessel stump into another using the telescoping technique may not itself be responsible for the failure of vein grafts interposed in an arterial defect, but distortion of the slack venous wall of the graft by high arterial blood pressure is.
