Occlusion of intercostal and lumbar aortic branches using plastic plugs.

Retrograde bleeding from the orifices of intercostal and lumbar arteries during aortic surgery is usually controlled by suture placement, a procedure that is time-consuming and may result in considerable blood loss. We have devised a method of occluding these arteries using polyurethane plugs. We have experienced no instances of perforation or delayed bleeding using this technique.
