[Computed tomography in the diagnosis and selection of surgical treatment for angiodysplasia].

Fifty-five patients (31 males and 24 females) with various localization of angiodysplasia (the region of the pelvis and pelvic organs, trunk, head and face, and the limbs) were examined. Comparison of angiography and computed tomography of the 55 patients showed that only 8 cases (15%) of arteriovenous angiodysplasia had vascular changes characteristic of angiodysplasia in arteriography. Changes of vessels were not revealed by phlebography, whereas computed tomography yielded a positive result in 54 cases. Thus, computed tomography, even without the use of contrast intensification, is the main method for the diagnosis of venous-cavernous angiomatosis of organs and deeply situated tissues. Computed tomography makes it possible to determine the tactic and volume of operative treatment and to control the efficacy of the applied treatment.
