Cineangiography in the diagnosis and evaluation of aortic dissection

Fourteen patients with suspected aortic dissection were studied with 35-mm biplane cineangiography, and the results were compared with those of previously obtained conventional large-film studies. There was no loss of radiographic information due to the decreased resolution of the cine technique. The detection of initial dissection sites, reentry points, and intimal flaps, and the evaluation of aortic regurgitation and the coronary ostia may be improved with cineangiography. The procedure time was shortened and repeat examinations were eliminated with the cine method. Consideration of this technique in evaluating aortic dissection is recommended.
