Venous aneurysms of the extremities. Report of 4 cases and review of literature.

Venous aneurysms are lesions that can be difficult to diagnose and may be a source of significant morbidity. Venous aneurysms have been reported to occur in most major veins, neck, central thoracic veins, and extremities. The authors report 4 cases of venous aneurysms: 1 of the upper and 3 of the lower extremity. All patients underwent aneurysmectomy with end-to-end anastomosis and no complications after surgery were reported. These cases are presented along with a review of literature and their origin, diagnosis, and treatment.
