Abstract:
Objective To explore the distribution characteristics and clinical typing methods in distal crevasses of Stanford B aortic dissection.Methods Review of the cases in the People's Hospital of Xinjiang Urgur Autonomous Region from 2010 January to 2013 June were diagnosis of Stanford type B aortic dissection with computed tomographic angiography data,Observed its distal crevasses distribution and statistical its number,then summarizes the distribution characteristics of the distal crevasses and further put forward a method of clinical typing.Results Refer to 115 cases with Stanford type B aortic dissection computed tomographic angiography data,including 101 cases with distal crevasses (87.83％) and a total of 240 distal crevasses,an average of 2.37 per case.Conclusions The distal crevasses more often appear in the area involving visceral artery,combined with its different in distribution characteristics and processing methods,we put forward the classification method,namely:Type Ⅰ:the distal crevasses are located in the zone of the thoracic artery; Type Ⅱ:the distal crevasses are close to the visceral artery or involvement it; Type Ⅲ:the distal crevasses are lower than the renal artery,not involving the visceral artery; Type Ⅳ:the distal crevasses are located in the zone of the iliac artery.
