Abstract
Background: Infrarenal aortic dissection, superimposed on chronic abdominal aortic aneurysm is rare. Case: A 58-year-old woman presented with severe lower back pain. On contrast computed tomography, she was found to have acute infrarenal aortic dissection and chronic infrarenal abdominal aortic aneurysm. At surgery, the proximal extent of the dissection was located near the renal arteries. A bifurcated graft was sewn to the dissected neck of infrarenal aorta, incorporating a felt strip to reinforce the true and friable false lumina onto the graft. Results: Her post operative course was uneventful. She was discharged 16 days after operation. Conclusion: This experience suggested that surgical repair during acute period, which calls into question tissue friability, can be accomplished with standard techniques.
