Abstract: | Popliteal artery aneurysms representing 80% of peripheral artery aneurysms rarely rupture (a reported incidence of 0.1–2.8
%) and second commonest in frequency after aorto-iliac aneurysms. They usually present with pain, swelling, occlusion or distal
embolisation and can cause diagnostic difficulties. We report a 78 year old man who was previously admitted to hospital with
a pulmonary embolus secondary to deep venous thrombosis. He was heparinized then warfarinised and was readmitted with a ruptured
popliteal aneurysm leading to a large pseudo aneurysm formation. The pulmonary embolus had been due to popliteal vein thrombosis
and propagation of the clot. A thorough review of literature identified only one previously reported case of ruptured popliteal
artery aneurysm and subsequent large pseudo aneurysm formation. We feel it is important to exclude a popliteal aneurysm in
a patient with DVT. This may be more common than the published literature suggests. |
