Rapid Development of De Novo Thoracic Aneurysm After Liver Transplant.

The development of aortic aneurysms in post-transplant patients is a rare but potentially lethal problem. De novo aortic aneurysm formation and rapid growth are postulated to result from an imbalance between pro- and anti-inflammatory vascular endothelial factors after transplant. Here, we present a case of de novo thoracic aneurysm formation within 2 months of orthotopic liver transplant. Prompt clinical recognition allowed for successful endovascular repair. Transplant clinicians should be aware of this potentially life-threatening complication and monitor at-risk recipients accordingly.
