RESUMO
Objective To review the clinical manifestation,diagnosis method,misdiagnosis,risk factors,treatments and prognosis of Stanford B aortic intramural hematoma (IMHB).Methods All of the Stanford B aortic IMHB patients admitted in Wuhan Union hospital from January 2008 to December 2013 were analyzed.The clinical manifestation,diagnosis method,misdiagnosis,managements and prognosis were studied.Furthermore,the effect and long-term survival of different therapies were compared,including medical treatment and endovascular repair.The statistics was performed with SPSS 16.0.Results There were 36 B aortic IMHB patients,and the percent of male patients was 72.22％.The mean age of IMHB was 60.19 ± 11.12.Most patients complained of acute chest and back pain,accompanied with hypertension.Twenty-eight patients (77.78％) received medication therapy,among them,there were 5 patients died of aortic rupture; eight patients (22.22％) received endovascular surgery,one died of cerebral hemorrhage (12.5％).No difference was found between medication therapy and endovascular surgery (17.86％ vs 12.5％,P ＞0.05).Conclusions For simple type B aortic IMHB patients,medication therapy and a dynamic monitoring of full aortic CT angiography was recommended,and for pejorative patients the endovascular treatment should be taken actively.
