Poplitealarterienaneurysma

Abstract

Aneurysms of the popliteal artery are the most common form of peripheral aneurysm with an incidence of 70-80 %. An enlargement of the popliteal artery of more than 50% of the original diameter is defined as a popliteal artery aneurysm and is found mainly in male patients older than 65 years of age. The incidence is 1%, in 50% of cases is bilateral and in up to 50% in association with other large vessel aneurysms (e.g. abdominal aorta). Differential diagnoses are Baker's cyst, cystic adventitial disease, entrapment syndrome and epitheloid hemangioma. One third of all diagnosed popliteal artery aneurysms are asymptomatic incidental findings, whereas two thirds are conspicuous due to symptoms (acute or chronic ischemia, local compression, rupture). The indications for invasive treatment are given for patients with patent aneurysms at a diameter of more than 2 cm or if a thrombus is present within the aneurysm. Symptomatic popliteal artery aneurysms are always an indication for therapy. Treatment strategies are surgical techniques and endovascular interventions, which both have a similar outcome and graft patency in midterm results.

Endovascular Treatment of Aneurysms of the Popliteal Artery by a Covered Endoprosthesis

“…We had a relatively small number (10) of PAAs treated with endovascular stenting compared with other studies that treated 24–178 patients. 9 , 18 , 20 , 22 , 23 Naturally, this is a limitation of our validity.…”

“…Technical success in all cases was also reported by several authors of the literature we are referring to. 17 , 20 , 22 , 23 …”

“…We have seen our patients for a mean follow-up of 24.7 months, and therefore, consider our observations as early results since most of the other authors reported from longer follow-ups of 22–72 months. 9 , 16 – 18 , 20 , 22 , 23 Follow-up modalities were duplex ultrasound and the ABI. ABI increased from 0.62 before to 0.91 after intervention and was 0.89 after 2 years.…”

Beyond the Baker's Cyst: Pathology and Variant Anatomy in the Popliteal Fossa on Routine Knee MRI

“…Popliteal artery aneurysms (PAAs) represent approximately 70% to 80% of all peripheral aneurysms and are primarily found in older males with atherosclerosis, with an overall incidence of 1% 15. Complications include distal thromboembolism, aneurysmal progression, and rupture 15. About half of PAAs occur bilaterally, and up to half of patients with PAAs additionally experience other large vessel aneurysms 15.…”

“…Complications include distal thromboembolism, aneurysmal progression, and rupture 15. About half of PAAs occur bilaterally, and up to half of patients with PAAs additionally experience other large vessel aneurysms 15. Therefore, screening for abdominal aortic aneurysms (AAAs) should be performed in those with clinically detectable PAAs, as AAAs have been found in up to 62% of symptomatic patients 16.…”
