Clampless Technique in Open Revascularization of Acute Mesenteric Ischemia
Abdominal aortic cross-clamping is required in many visceral bypass operations, but results in increased risk of postoperative morbidity. Originally developed for coronary artery bypass grafting, the PAS-Port Proximal Anastomotic System (Cardica Inc., Redwood City, CA) creates sutureless proximal aortic anastomoses without the need for cross-clamping, although its use elsewhere in the body has not been reported. In this video, the authors use the PAS-Port Proximal Anastomotic System in the abdominal aorta procedure as a viable alternative to traditional anastomotic techniques.
