ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the evolution of medically treated atherosclerotic aortic ulcers by computed tomography (CT).</p><p><b>METHODS</b>Thirty-five patients (31 men and 4 women, aged from 40 to 79 years, mean 56.2 +/- 10.8 years) with known aortic ulcers were monitored by CT (follow up time 7 - 730 days, mean 135 days), 80 - 100 ml contrast media (Ultravist 300 or 320, or Omnipaque 300 or 320 mg/ml) was injected with a rate of 3.5 - 4.5 ml/s. The scan delayed time was 18 - 30 s. Ulcers dimensions were measured according to maximum depth, maximum length and maximum width.</p><p><b>RESULTS</b>Thirty-one patients with intramural hematomas and 1 patient with atherosclerotic aortic arch aneurysm without intramural hematoma were medically treated and another 3 patients were surgically treated. Intramural hematoma regression was monitored in 31 medically treated patients with intramural hematomas. CT was repeated at 2 weeks, 3 and 6 months. Intramural hematoma resolved gradually during follow up [thickness (7.69 +/- 4.24) mm at 3 months, (3.06 +/- 1.67) mm at 6 months, P < 0.05 vs. 1st CT (11.96 +/- 4.16) mm while ulcer maximum depth (11.17 +/- 6.03) mm at 3 months, (11.35 +/- 5.59) mm at 6 months, P < 0.05 vs. 1st CT (7.36 +/- 6.61) mm, maximum width (14.40 +/- 6.35) mm at 3 months, (18.55 +/- 10.94) mm at 6 months, P < 0.05 vs. 1st CT (7.15 +/- 6.39) mm, maximum length (17.12 +/- 7.15) mm at 3 months, (18.13 +/- 10.89) mm at 6 months, P < 0.05 vs. 1st CT (11.64 +/- 10.06) mm increased progressively during follow-up].</p><p><b>CONCLUSION</b>CT was a useful tool for deflecting atherosclerotic aortic ulcers and monitoring therapeutic effects.</p>
