Hypothesis:
Percutaneous endovascular repair of ruptured abdominal aortic aneurysms (RAAAs) has better outcomes than traditional open surgical repair.
Design:
Single-center retrospective review.
Setting:
University hospital tertiary referral center.
Patients:
Thirty-seven RAAAs treated using endovascular repair (n = 15) or open surgery (n = 22).
Interventions:
From January 1, 2000, through December 31, 2005, 15 RAAAs were treated with endovascular stent graft exclusion using commercially available systems. Twenty-two other patients undergoing standard open surgical repair during the same interval comprised a control group for comparison.
Main Outcome Measures:
Early outcomes of percutaneous endovascular repair of RAAAs.
Results:
Among the endovascular group, the mean +/- SD age was 73 +/- 9.8 years, 86.6% were men (n = 13), and 20.0% had a preoperative systolic blood pressure of 80 mm Hg or lower (n = 3). An entirely percutaneous procedure was performed in the final 11 patients using arterial closure systems. Technical success of attempted endovascular exclusion was 100.0%. The mean +/- SD procedure time (107 +/- 30 minutes), transfusion requirements (6.6 +/- 4.7 U), and length of stay (3.0 +/- 6.8 days) were statistically significantly reduced compared with open surgery. The 30-day mortality was 6.7% (1 of 15) compared with an open surgery 30-day mortality of 13.6% (3 of 22). No late complications (pseudoaneurysm, infection, lymphocele, or neuropathy) occurred after a completely percutaneous technique during a mean follow-up of 12 months.
Conclusion:
Percutaneous endovascular repair of RAAAs is a more expedient and less morbid alternative than open surgical repair.
