Thoracoabdominal Aortic Repair of DeBakey Type IIIb Dissecting Aneurysms / 日本心臓血管外科学会雑誌

ABSTRACT

Nine patients with type IIIb dissecting aortic aneurysm underwent graft replacement of the thoracic and abdominal aorta between 1988 and 1992. The spiral opening method was used to expose the thoracic and abdominal aorta. Temporal bypass was employed in 2 patients and F-F bypass in 7 patients. Visceral arteries were perfused selectively during aortic cross-clamp. The entire descending thoracic aorta and abdominal aorta was reconstructed in 6 patients and the proximal descending thoracic aorta to renal arteries in 3 patients. The Crawford graft inclusion technique was used in all cases. Three patients required emergency surgery for rupture in one and impending rupture in 2. Operative deaths occurred in 2 patients (22.2%). Morbidity included renal failure (2), bleeding requiring reoperation (2), arrythmia (1), paraplegia (1), paraparesis (1), respiratory failure (1) and ileus (1). In the past two years, we operated on 5 cases of type IIIb dissecting aneurysms and there was neither operative death nor paraplegia.
