The experience of an academic medical center with endovascular treatment of abdominal aortic aneurysms.
BACKGROUND
Endovascular repair of abdominal aortic aneurysms (AAA) is gaining momentum although it is not yet approved in the United States by regulatory agencies. The Endovascular Grafting System (EGS), the first device to enter clinical trials in 1993, is now in phase III testing.


METHODS
We reviewed the first 50 patients to undergo an EGS repair of AAA over 24 months at our institution. Results were compared with 69 patients who underwent open repair during the same time period by the same surgeon.


RESULTS
Devices were successfully implanted in 47 of 50 (94%) patients. Three were converted to standard repair. Although length of stay was shorter, costs were similar. Follow-up was 3 to 24 months. Perigraft flow was noted in 33% at discharge; 73% of those stopped either spontaneously or with coiling. Three graft limbs occluded, requiring thrombolytic therapy.


CONCLUSIONS
The EGS repair of AAA is feasible and effective. Cooperation between surgery and radiology is important for the success of a new endovascular program.
