Clinical Studies of "Closing Aortic Dissection" / 日本心臓血管外科学会雑誌

ABSTRACT

Those cases in which a dissected lumen closes early in the onset of acute aortic dissection and produce a“dissected lumen with no blood flow”are regarded as a clinico-pathological entity and are called a“closing aortic dissection”, and the clinical picture and clinical course of 14 cases in which the clinical course could be observed from early onset were reported. Although 13 cases resulted in complete closure of the dissected lumen, one case initially showed incomplete closure, but subsequently closed completely. Two cases resulted in reopening of the blood flow, but the disease recurred, and by four and six weeks each had incompletely or completely reclosed. Consequently, there were three cases of entry observed and scars of entry were found in three other cases. And in eight cases, there was nothing observed at all. Although one patient died because of complications of secondary type I acute dissection, all the others survived. All told, the developmental mechanism of this disease was alluded to.
