Abstract

PURPOSE: To evaluate the effectiveness and safety of endoluminal bifurcated stent graft for the treatment of AAA.
MATERIALS AND METHODS
Between August 1997 and August 1998, 20 patients with AAA underwent treatment involving the use of a bifurcated stent graft. Fourteen in whom the aneurysm involved only bifurcation and six patients in whom the common iliac arteries were involved. For one patient, a stent with a short proximal neck measuring 12 mm was used. The stent graft was inserted by means of a unilateral surgical femoral arteriotomy. After the procedure, follow up involving CT and aortography was performed between month 3 and month 12.
RESULTS
The primary success rate with the first trial was 79 percent (15 of 19 patients), and the overall success rate was 84 percent; one perigraft leak was successfully corrected. In one case, technical failure occurred due to a tortuous iliac vessel and spasm. Procedure-related complications occurred in 16% of patients (3 of 19), one of whom died due to acute renal failure following a contrast overdose.
CONCLUSION
Endovascular treatment of infrarenal AAA by means of a bifurcated stent graft was effective and safe. In particular, if the proximal neck measured more than 1cm, any AAA could be treated using bifurcated stent graft. Further investigation of the outcome and complications arising during long-term follow-up are needed, however.
