Acute Popliteal Artery Occlusion after Revision Total Knee Arthroplasty

الملخص EN

Acute arterial occlusions are a rare complication of total knee arthroplasty (TKA).

However, in revision TKA, the risk of such complications is higher and these complications can lead to amputation if not adequately treated.

We describe a case of acute popliteal artery occlusion 4 hours after second revision TKA in a patient with a history of several surgical procedures because of periprosthetic infection at a previous hospital.

Revascularization was achieved via bypass grafting and amputation was narrowly avoided despite time lag after symptom onset to revascularization.

In this case, it was possible that the arterial disease that accompanied the vascular endothelium injury such as pseudoaneurysm had existed since the previous surgery at another hospital and was destroyed by the surgical procedure, which led to the formation of thrombosis and arterial occlusion.

Preoperative evaluation of the arterial condition should be considered to avoid acute arterial occlusive disease, especially in patients who had several previous surgical procedures.
