Surgical Therapy for Juxtarenal Aortic Occlusion / 日本心臓血管外科学会雑誌

ABSTRACT

The surgical anatomical bypass (ANA) procedures for juxtarenal aortic occlusion (JAO) have been recently developed. However, there are some critical conditions, in which we should be cautious concerning the indications of ANA. Between 1984 and 1993 in Kurume University Hospital, 17 patients with JAO were operated upon. The most common cheifcomplaint was claudication (70.6%). Acute deterioration due to ischemia was recognized in two patients (11.8%). ANA was performed in 15 patients (88.2%) and extra-anatomical bypass (EXT) in 2 with severe calcification of the aorta (11.8%). Hospital deaths occured in three patients with ANA (17.6%), whose background included two acute deterioration and one cerebral infarction with hemiplegia. As an early postoperative complication, acute renal failure occurred in one patient and subileus in two. In the presence of poor general condition, acute deterioration, or severe aortic calcification, the EXT-procedure is the choice of surgical treatment for JAO.
