Endovascular Treatment for Traumatic Popliteal Artery Pseudoaneurysms After Knee Arthroplasty

Abstract

Trauma to the popliteal artery is a recognized complication of knee arthroplasty (total knee arthroplasty). It can present in a variety of ways, one of which is the development of popliteal artery pseudoaneurysm. We report the successful endovascular management of 2 patients who developed popliteal artery pseudoaneurysms following total knee arthroplasty using covered stent grafts. From presented evidence, endovascular therapy is a safe treatment modality and it appears to be a viable alternative to open surgery.

Posttraumatic pseudoaneurysm of popliteal artery following total knee arthroplasty

“…The diagnosis of a post TKA popliteal artery pseudoaneurysm should be suspected clinically, and diagnostic tools such as Doppler ultrasonography and CT angiography should be used to confirm the diagnosis 15–16. Repeat ultrasonography is also valuable in determining whether the aneurysm is increasing in size.…”

“…Vascular complications after a total knee arthroplasty (TKA) occur in less than 0.5% of cases 1. It is uncommon, with a reported incidence following TKA ranging from 0.03 to 0.17% 2–7.…”

Endovascular repair of a pseudoaneurysm of the popliteal artery following arthroscopic knee surgery: case report and review of literature

“…11 There have been a limited number of studies on the safety and long-term outcomes of endovascular repair on popliteal artery pseudoaneurysms; however, based on the current literature, endovascular treatment can be safe and durable with surveillance for stent fracture and migration using duplex ultrasound or radiography. 3,4 Covered stent grafts are used in the treatment of large popliteal In conclusion, endovascular repair is a viable option for the treatment of popliteal artery pseudoaneurysms, but there still needs to be further long-term studies on whether it should be the preferred treatment, compared with open repair.…”

“…1,[3][4][5][6][7][8] This complication can be life threatening with the potential for limb loss. We present an unusual case of a popliteal artery pseudoaneurysm following arthroscopic knee repair of a left meniscus tear that was successfully treated percutaneously by a covered stent.…”

Popliteal Artery Pseudoaneurysm Following Primary Total Knee Arthroplasty

“…Conditions associated with peroneal nerve injury after TKA include flexion contracture, valgus deformity, postoperative epidural analgesia, external leg compression, increased tourniquet duration, postoperative hematoma, and history of nerve root compression2). The current clinical diagnostic criteria for popliteal artery pseudoaneurysm are the presence of a pulsatile hematoma with an audible bruit and swelling over the popliteal region and the entire lower leg3).…”
