Abstract:
Objective To determine the value of helical CT for the follow up of patients with abdominal aortic aneurysms(AAAs) after graft implantation. Methods Twenty six patients with AAAs underwent helical CT within 3 days after graft placement. Additional follow up CT scans were obtained in 22 patients 3 months after placement. The diameter of the aneurysmal sac, complications of the procedure, position, shape, and patency of the device were recorded. Results CT scans obtained within 3 days after placement showed complete thrombosis of the aneurysm in 20 patients, and 6 patients with perigraft channels; 3 months later, of 17 thrombosed aneurysms, 9 decreased in diameter, 7 remained unchanged, and 1 increased in diameter; of 5 aneurysms with perigraft channels, 2 decreased in diameter, 2 were stable, and 1 became enlarged. 20 of 26 patients (76.92%) were successful with endovascular repaire. Conclusion Helical CT is a valuable means in follow up of the patients after endovascular repair.
