Complications and Prognoses of Patients Treated for Stanford Type B Aortic Dissection / 日本心臓血管外科学会雑誌

ABSTRACT

In the past 11 years, we treated 41 patients with Stanford type B aortic dissection. Principally, medical therapy was carried out and surgery was performed only when complications related to the dissection occurred. Twenty two patients (53.7%) had complications, including 5 (12%) with peripheral limb ischemia, 3 (7%) with rupture, 13 (32%) with dilatation of the aorta, 4 (10%) with extension of dissection (type A dissection). Seventeen patients received surgery including palliative operation. Among 41 patients, 3 died due to aortic rupture and 2 died at surgery for type A dissection, while 4 of them had developed proximal extension of the dissection. The 5-year survival rate for all patients was 86.7±6.6%. Long term survival will improve in patients with Stanford type B aortic dissection when the operative mortality for type A dissection is reduced and sound management policies are developed.
