Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis.

OBJECTIVE. Wereport ourprospective studyevaluating biphasic helical CT of theaorta after endoluminal stern-graft placement. SUBJECTSAND METHODS. Biphasic helical CT scans in95 patients withabdominaland thoracic aortic aneurysms who had undergone endoluminal stent-graft placement were re viewed. After a test bolus injection of 15 ml of contrast media at a rate of 3.5 mi/sec for the measurement of the optimal start delay, the aorta was scanned using the following parameters: collimation of 5 mm, table speed of 7 mm per rotation, tube rotation time of 0.75 sec, 120 kV, and 295 mA. A delayed helical CT scan was obtained I5 sec after the initial acquisition using the same parameters.

Transcatheter embolization of perigraft leaks appears to be an effective technique to achieve aneurysmal thrombosis.

Transluminal placement of endovascular stent-grafts for treatment of penetrating ulcers of the descending thoracic aorta appears to be a possible alternative to classical surgery. After treatment, follow-up by CT is essential to detect possible complications of the disease.
