[Type A aortic dissection: the role of angiography in identifying morphologic features in comparison with autopsy and surgical findings].
To evaluate the reliability of cineangiography in identifying some morphologic characteristics of type A aortic dissection, the angiograms of 36 consecutive patients were retrospectively revised and compared with the surgical of necropsy findings. The following features were examined: site and extension of intimal tear (s); extension of the wall dissection; coronary and brachiocephalic arteries involvement; coexisting anuloaortic ectasia; aortic valve state. The angiographic diagnosis of site and extension of the intimal tear was correct in 97 (35/36) and 100% of cases respectively. In one case the presence of an intimal tear at the level of the aortic arch was missed because of the superimposition of the innominate artery. The extension of the wall dissection was correctly identified in 24 out of 25 patients. In one case the presence of distal false lumen thrombosis made the correct diagnosis impossible. The brachiocephalic arteries involvement was always correctly stated while the coronary involvement was suspected in 6 and confirmed in 5 (1 false positive). Anuloectasia was suspected in 12 and confirmed in 10 (2 false positives). In our experience the most challenging diagnosed were the presence of aortic arch tears and the aortic arch and coronary arteries involvement in the dissection. This study confirms that many morphologic features of type A aortic dissection can be adequately assessed by cineangiography.
