Abstract:
Aneurysms of the inferior vena cava (IVC) are rare, with only 54 cases reported in the literature. They carry a significant morbidity and mortality risk. A case of an IVC aneurysm in a patient with Klippel-Trenaunay syndrome (KTS) is reported. Open aneurysmorrhaphy of the type III aneurysm was successfully performed. The patient's leg swelling, back pain, and exercise tolerance improved. IVC aneurysms are not known to be associated with KTS. However, clinicians should have a high index of suspicion for great vessel aneurysms in these patients as they are associated with greater thromboembolic risk.
