Popliteal Artery Aneurysms
Thursday, August 29, 2013

 

 

Popliteal artery aneurysms can occur by themselves or in association with other aneurysm, namely aortic artery aneurysms and aneurysms of the femoral artery.  The definition of a popliteal artery aneurysm is when the diameter is 50% larger than the normal vessel.

 

Popliteal artery aneurysms are the most common type of true peripheral artery aneurysms – they occur more frequently than femoral artery aneurysms but less frequently than aortic artery aneurysms.  10% of patients with aortic artery aneurysms have popliteal artery aneurysms.

 

The vast majority patients with popliteal artery aneuryss have a smoking history.  Approximately 40% of patients with popliteal artery aneurysms have an abdominal aortic aneurysm.  Indications for surgery in patients include large size, symptomatic aneurysms, chronic ischemia, and acute thromboembolism as well as rupture.

 

Diagnosis can be made by physical examination if they are quite large or by duplex ultrasonography, CT angiography or magnetic resonance angiography.

 

Elective repair is suggested in aneurysms larger than 2 cm in size even if they are asymptomatic.  Aneurysms less than 2 cm of size are typically observed and serial physical examination and duplex ultrasonography is performed every 6 to 12 months.
