Acute limb ischemia due to popliteal artery thrombosis after
Popliteal artery thrombosis is a very rare complication in total knee arthroplasty (TKA) surgery, which is more commonly caused by indirect mechanism than direct mechanism. If not treated early, it leads to limb amputation and rarely may lead to mortality.

Although bypass grafting is the mainstay of treatment done in many cases, endovascular therapy is a potential alternative in acute setting for limb salvage. There are only few case reports of endovascular therapy in this setting.

Published in the Indian Journal of Vascular and Endovascular Surgery, the authors report a case of acute limb ischemia due to popliteal artery thrombosis immediately after TKA which is salvaged by endovascular therapy with endoluminal thrombosuction and balloon inflation only.

A 55-year-old female with no conventional risk factors for atherosclerosis was suffering from bilateral arthritis of knee joint from 10 years. She was on long-standing steroids for arthritis and underwent TKA in the standardized approach. The surgery was performed through a standard midline approach and a median parapatellar arthrotomy.

Her left limb below the knee was cooler than the right limb and capillary refill time was prolonged. Neurologic examination revealed moderate weakness in the left lower limb distal muscles and moderate nerve paresthesia with no dorsiflexion or plantar flexion of the ankle joint.
