PURPOSE: The prognosis and treatment of type B intramural @entity1410 (IMH) remain unclear. Intimal @entity2681 could be the target of preventive endovascular treatment, but we have no therapeutic criterion on which to decide preventive treatment. MATERIALS AND METHODS: A prospective multislice computed tomography (CT) study was carried out in 44 @entity1 with type B IMH to assess morphologic evolution and intimal erosion to determine reliable predictive factors that would permit endovascular treatment. Follow-up range was 24-1,440 days. RESULTS: Intimal anomalies consisted of intimal erosion and @entity7244 . Fifty-eight intimal anomalies were seen on initial CT in 38 @entity1 (86%). Twenty-five anomalies in 22 @entity1 were considered as intimal @entity2681 , of which nine (36%) were visible only on delayed-phase CT. @entity1410 regressed in 23 @entity1 (53%). Twenty-one @entity1 (47%) showed morphologic progression. Eleven of these (52%) required endovascular treatment. Twenty of the 25 initial intimal @entity2681 (80%) progressed and caused 19 of the 21 morphologic evolutions (90%). Progression was related to @entity1613 and to IMH thickness. Intimal erosion measuring greater than 10 mm had unfavorable progression at 1 month (positive predictive value, 100%). CONCLUSIONS: Complications or morphologic progression were related to a preexisting @entity154 visualized on initial CT. Multislice CT with systematically delayed phase and millimetric thin slices could increase the detection rate of intimal anomalies.
