title: Thrombotic complications of venous aneurysms.
abstract: BACKGROUND
  Venous aneurysms are rare vascular anomalies that have been reported to occur throughout the body. We report a unique variation, namely a thrombosed subclavian vein aneurysm.
  
  
  METHODS
  A review of the records of patients with documented venous aneurysms presenting to the St George Hospital and their associated imaging was made. A literature search for articles pertaining to venous aneurysms was performed.
  
  
  RESULTS
  Four cases of venous aneurysms were identified; one subclavian vein, one inferior vena cava and two popliteal. The clinical course of these cases is detailed, along with a review of the literature.
  
  
  CONCLUSIONS
  Venous aneurysms are infrequent findings and indicate that the patient is at significant risk of thrombosis. Popliteal vein aneurysms should be treated surgically.
