Popliteal venous aneurysm
Popliteal venous aneurysm is a rare disease. The diameter of the vein is at least twice as big as the normal proximal vein. The aneurysm is usually asymptomatic but it can suddenly cause pulmonary embolism even in young persons. Due to an unpredictable risk of thromboembolism even under anticoagulation treatment operation is often advisable if the diameter of the aneurysm is more than 20 mm. The operation can usually be done as tangential aneurysmectomy and lateral venorrhaphy which has a low complication rate and a good patency.
