Introduction: True para-anastomotic aneurysms are a rare complication of arterial surgery.

Objective: This paper aims to describe the clinical case of a 73 years-old patient, with history of a left above-the- -knee amputation due to an occluded popliteal aneurysm, admitted for surgical treatment of a contralateral popliteal aneurysm.

Results: A bypass between the right distal superficial femoral artery (SFA) and the distal popliteal artery was performed using autologous vein. Two years after the index surgery, aneurysmatic degeneration of the native artery was found on ultrasound, with 1.7 cm at the proximal anastomosis, and 1.4 cm distally. We kept surveillance, however, 12 years after surgery, he had a proximal true para-anastomotic aneurysm of the SFA with 4.8 cm. So, resection with interposition of a prosthetic graft between the native artery and the venous conduit of the previous bypass was performed. At this time the popliteal artery at the distal anastomosis had, approximately, 1.8 cm, so we chose to remain vigilant. Seventeen years after surgery, it measured 3.2 cm, in computed tomographic angiography. Therefore, total aneurysmectomy was performed and, due to redundancy of the previous bypass venous conduit caused by progressive dilation restricted to the distal popliteal artery, we did a termino-terminal reanastomosis to the normal sized popliteal artery. After 20 months, he is asymptomatic, with distal pulses present, without clinical nor radiological signs of aneurysmal degeneration.

Discussion And Conclusion: This work aims to highlight the relevance of the follow up, not only on a clinical basis but also radiological, since we are dealing with a diffuse pathology that can appear in any arterial segment without symptoms.

[Cystic adventitial disease of the popliteal artery].

Rev Port Cir Cardiotorac Vasc 2016 Jul-Dec;23(3-4):171-173

Although rare, popliteal artery cystic adventitial disease (CAD) is one of the most common non-atheromatous causes of intermittent claudication. This work aims to describe the clinical case of a 50 years old male patient with symptomatic popliteal artery CAD, presenting with calf intermittent claudication for long distances on flat but 50m in ascending plane, which affected his life quality. On examination he presented with normal coloration and temperature of the lower extremities, with distal pulses present at rest. By flexing the right knee, he lost distal pulses. On ultrasound was found a cystic formation surrounding the right popliteal artery, so a MRI was done and confirmed the presence of an adventitial cystic surrounding about 50% of the artery at the popliteal fossa with 31x13x17mm. He underwent surgery with a posterior approach followed by cyst removal, preservating the media of the artery, and ligation of a ductus that seemed to extent from the articular capsule. At the fourth post-operative day he was discharged and remained without symptoms nor recurrence during the follow up. The CAD usually affects the popliteal artery (85%). It's more common in men with 35-40 years and the prevalence is estimated at 1/1200 claudicants. The symptoms are caused, usually, by extrinsic compression of the artery. Ultrasound, today, is the first line exam, and might be complemented with others to confirm the diagnosis and plan the treatment. The surgical treatment may vary from drainage to segmental arterial resection in case of significant degeneration. The prognostic is usually favorable.
