Background:
There is a paucity of literature regarding thoracic endovascular aneurysm repair (TEVAR) in women. We report our institutional experience with TEVAR.
Methods:
Retrospective chart review was performed from 2004 to 2008. TEVAR was performed in 59 patients; 29 (49%) were female.
Results:
Mean age was 73.5 years. Mean thoracic aortic aneurysm (TAA) diameter was larger for women (5.9 cm vs 4.7 cm). A trend toward an increase in paraplegia was noted in women, 10.3% vs 4.8%. This may be related to increase in length of aortic coverage in women, 18.2 cm vs 15.2 cm (P < .05).
Conclusion:
TEVAR in women is safe and effective. The length of aortic coverage is greater in women, which may be related to larger aneurysms and more diffuse disease. This may be associated with a concerning increase in postoperative paraplegia. Women undergoing TEVAR should be considered for prophylactic maneuvers to prevent spinal cord ischemia (SCI), including minimizing length of coverage.
