Cardiopulmonary bypass established via a sutured vascular graft in the presence of extraanatomic bypass

Cardiopulmonary bypass (CPB) was established via a sutured collagen sealed knitted Dacron graft in two patients who had undergone extraanatomic bypass es for lower limb ischemia, whose ascending aorta was not suitable for cann ulation. One patient, with a history of femorofemoral bypass, underwent sur gery for a ruptured aortic arch aneurysm (AAA) and the other patient, with a history of axillobifemoral bypass for chronic dissection involving the ao rtic arch and descending aorta, had unstable angina and underwent coronary artery bypass grafting. This technique of perfusion was found to be safe an d effective for patients with an impaired ascending aorta who have undergon e an extraanatomic bypass for the lower limb.
