Abstract

Elective treatment of descending thoracic aneurysms involves direct surgery, with Dacron graft replacement of the diseased aortic segment. When the patient's condition contraindicates major surgery, however, the surgeon should consider using an extraanatomic approach-implanting an ascending aorta-to-abdominal aorta Dacron bypass graft in a ventral position and leaving the diseased segment undisturbed. After such a procedure, the descending thoracic aorta must be excluded from the normal circulation. For this purpose, we have designed an intraaortic occluding technique in which an umbrella-like device is implanted immediately distal to the left subclavian artery. This technique has proved safe and uncomplicated in canine experiments and is ready for clinical trials.
