Purpose: We report early experiences on endovascular abdominal aortic aneurysm repair (EVAR).
Method: We reviewed the results of 15 patients underwent EVAR between 2003 and 2007 in the Kyung Hee University Medical Center, retrospectively.
Result: Mean age of patients was 71.2 years (range, 51∼85 years). 14 patients (93.3%) had comorbidities. All of AAAs were infrarenal types. The mean size of AAA was 58.5 mm (38∼91 mm), and the mean length, diameter, and angle of neck was 26.4 mm, 19.9 mm, and 37.7o, respectively. Ten patients were accompanied with iliac aneurysm. 14 were bifurcated grafts and 1 was straight tubular graft. Mean procedure time was 100.6 minutes. Mean length of hospitalization was 6.5 days (2∼10 days). There was no need of transfusion or use of an intensive care unit. Fever of unknown origin occurred in 7 cases but resolved spontaneously. Device deployment was successful in 100% (primary 9 cases, assisted-primary 6 cases). There were seven endoleaks during interventions. One patient with secondary type II endoleak and suprarenal enlargement of AAA sac died from aortoenteric fistula. In one patient with perigraft abscess after EVAR, surgical drainage was performed. Decrease of AAA diameter ≥5 mm in two patients, newly developed suprarenal aortic aneurysm in one patient were detected on CT scan during mean follow-up of 11.4 months (2∼29 months) and remained unchanged in other twelve cases.
Conclusion: These early results suggest that EVAR offers considerable benefits for appropriate patients, but is thought to need more experiences and long-term outcomes.
