Prognosis of Stanford Type A Acute Aortic Dissection without Aortic Reconstruction / 日本心臓血管外科学会雑誌

ABSTRACT

Six cases without aortic reconstruction for 48 hours were encountered among 22 cases of Stanford type A acute aortic dissection from April, 1990 to July, 1996. They were one man and five women, with a mean age of 60.3 years old (from 52 to 82 years old). According to Hagiwara's definition, acute thrombotic aortic dissection (ATAD) was observed in four and acute opacified aortic dissection (AOAD) in two of six cases of Stanford type A acute aortic dissection without aortic reconstruction. One of the four ATAD cases was well-controlled by medical therapy, but the others could not be controlled and underwent aortic root reconstruction within 1 month. Two AOAD patients died due to rupture within 1 month. It is said in general that the patients with acute thrombotic aortic dissection can be treated medically, but we consider that they should be treated surgically because of the frequency of late rupture.
