Complications of stent grafts for popliteal aneurysms
Published in Sachinder Singh Hans, Mark F. Conrad, Vascular and Endovascular Complications, 2021
At the completion of endovascular treatment for popliteal artery aneurysm, nearly all patients had reported success. This was defined as exclusion of aneurysm, absence of endoleak, and preservation of distal run-off. On follow-up imaging some patients were found to have re-perfusion of the aneurysm sac. As popliteal artery aneurysm is not as commonly found to exert mass effect and rupture as it is to thrombose or embolize, this has been deemed less of an issue with respect to guiding subsequent treatments. Endoleak types mirror those as described with endovascular repair of abdominal aortic aneurysm (EVAR).43 Most studies suggest absence of definable endoleak upon completion imaging.36,37,39 Despite this initial success, 5–10% of these patients were found to have evidence of endoleak on follow-up imaging modalities.5,9,29 One study suggested that upward of 15% (8/57) of interventions were complicated long term by stent graft migration leading to Type I or III endoleak.37 See Figures 11.3 and 11.4.

A 63 year old male patient is seen in the vascular clinic with a pulsatile mass posterior to his right knee. Ultrasound confirms a 2-cm right popliteal artery aneurysm. The vascular team request a CT angiogram to help plan management.

It is standard practice to examine the femoral, popliteal, posterior tibial and dorsalis pedis arteries together with the abdomen for an aortic aneurysm or renal artery bruit, which may coexist with lower limb occlusive disease. Diminution of a femoral and/or popliteal pulse can often be appreciated by comparing it with its opposite number; however, pedal pulses are either clinically palpable or absent. Popliteal pulses are often difficult to feel; a popliteal artery aneurysm should be suspected if the popliteal pulse is prominent with concomitant loss of the natural concavity of the popliteal fossa. Pulsation distal to an arterial occlusion is usually absent although the presence of a highly developed collateral circulation may allow distal pulses to be palpable this is most likely to occur with an iliac stenosis. In this case, exercise (walking until claudication develops) usually causes the pulse to disappear as vasodilation occurs below the obstruction, causing the pulse pressure to reduce. An arterial bruit, heard on auscultation over the pulse, indicates turbulent flow and suggests a stenosis. It is an unreliable clinical sign as tight stenoses often do not have bruits. A continuous ‘machinery’ murmur over an artery usually indicates an arteriovenous fistula.

The most common presenting symptom for ACD affecting the popliteal artery is intermittent claudication of the lower extremity that is usually of acute onset and may progress rapidly.1,2 Of note, the claudication associated with ACD takes longer to resolve, which has been thought to be due to an increase in pressure during exercise causing increased fluid secretion and subsequent slow resorption of the secretions.1,2 Other presenting symptoms of popliteal artery ACD include burning pain and paresthesia of the affected lower extremity, pain behind the knee, acute calf pain, cyst rupture (rarely), ischemic rest pain, and tissue loss.1–3 Among conditions on the differential diagnosis that affect the popliteal artery and may also present with intermittent claudication are popliteal artery entrapment syndrome and popliteal artery aneurysm.4
