Purpose: To assess the role of OR in treatment of AAA patients, we reviewed the indications and our current results of OR of AAA.
Methods: We retrospectively investigated the database of 366 patients (mean age, 68.3±8.7 years, male 86%) who underwent open surgical (n=291, 80%) or endovascular treatments (n=75, 20%) of AAA in a tertiary referral center between Sep. 2003 to Aug. 2010. Treatment-related morbidities and mortality rates within 30 days were investigated according to the indications for treatment, clinical features, anatomic location, and underlying causes of AAA.
Results: According to the location of AAA, we treated 343 (94%) infrarenal, 17 (5%) juxtarenal and 6 (2%) suprarenal AAAs. Underlying causes of AAA were degenerative (90%), infected (3%), inflammatory (3%), Marfan’s syndrome (2%), and vasculitis (0.5%). Clinically, 338 (92%) were non-ruptured and 28 (8%) were ruptured AAAs. 75% of patients were treated with OR after the inception of reimbursement of aortic device while 25% of patients were treated with EVARs. The operative mortality rates of OR was 0.4% in patients with non-ruptured infrarenal AAA, 0% in patients with non-ruptured juxta- and suprarenal AAA and 21.4% in ruptured AAA patients.
Conclusion: In an era of endovascular treatment of AAA, we have experienced excellent surgical results after OR in patients with non-ruptured AAA with various clinical features. Though EVAR is rapidly replacing OR in treatment of infrarenal AAAs, OR has its own role in treatment of AAA patients with unfavorable conditions for EVAR. The role of OR should not be underestimated.
