Experimental saccular aneurysms. II: A new model in swine

摘要: A new technique for surgical construction of experimental lateral saccular aneurysms on the common carotid artery swine is described. It involves end-to-side suturing an isolated segment vein to artery. During a short period parent clamping, elliptical arteriotomy fashioned through open-ended graft, open end which subsequently tied and clamps are removed form aneurysmal pouch. The principal advantage this vascular clamping necessary isolate This prevents severe endothelial injury prolonged postoperative vasospasm, both may promote intra-aneurysmal thrombosis. Narrow- or wide-necked can be created. Steps in model detailed, specific advantages using highlighted.
