Cystic Adventitial Disease of Popliteal Artery with Venous Aneurysm of Popliteal Vein: Two-Year Follow-Up after Surgery

Abstract

We report a rare case of cystic adventitial disease of popliteal artery with venous aneurysm of popliteal vein. A 46-year-old woman had sudden-onset intermittent claudication and coldness in her right leg. The right-sided ankle-brachial pressure index (ABI) was 1.01, but peripheral arterial pulsation was decreased at knee venting position. Computed tomography revealed simple cystic lesion of the popliteal artery and stenosis of the arterial lumen in this lesion. The patient was treated by complete resection of the cystic adventitial layer of popliteal artery. A venous aneurysm of popliteal vein was revealed by intraoperative echo and was simply ligated. The patient had uneventful postoperative course and no symptoms of relevance during the two years of follow-up.

Microglial TLR4 is Critical for Neuronal Injury and Cognitive Dysfunction in Subarachnoid Hemorrhage

“…Cerebral injury seen after SAH is largely mediated by neuroinflammation secondary to lysed red blood cells releasing proteins such as heme, methemoglobin, and high mobility group box-1, all of which are ligands for TLR4 [29,30]. Our results suggest that microglia, and specifically microglial TLR4, are crucial for neuronal damage and cognitive dysfunction.…”

Cystic Adventitial Disease of the Popliteal Vein: A Case Report

“…The specific treatment method should be selected according to the shape, location, degree of stenosis of the cystic lesions, and the relationship with the surrounding blood vessels. 12 Cyst resection and bypass can be used to treat complete vascular occlusions. Local angioplasty has poor efficacy and a high recurrence rate during the early follow-up.…”

Ultrasound finding of cystic adventitial disease of the popliteal artery—A rare diagnosis for claudication

“…This occurs due to the mucoid cysts in the adventitia compressing the arterial walls and therefore limiting the flow through the affected portion of the artery. 10 CAD can also lead to complete occlusion of the affected artery and therefore a rapid and accurate diagnosis is important for the correct treatment to be performed before this occurs. 7,9,11 Occasionally the patient may also present with a palpable mass within the popliteal fossa as reported by Kawarai et al and Peterson et al 1,12 Although CAD has a slow progression, once the patient becomes symptomatic with claudication the progression can be rapid.…”

“…Patients with CAD of the popliteal artery normally present with symptoms of intermittent claudication, 7 as did the patient in this case. This occurs due to the mucoid cysts in the adventitia compressing the arterial walls and therefore limiting the flow through the affected portion of the artery 10 . CAD can also lead to complete occlusion of the affected artery and therefore a rapid and accurate diagnosis is important for the correct treatment to be performed before this occurs 7,9,11 .…”
