- Abstract: Popliteal pseudoaneurysms are often due to traumatic injury or are iatrogenic, such as from orthopedic surgery, and require urgent reconstruction. We report a case the onset of which was due to kneeling on the floor. The patient developed a large pseudoaneurysm because the symptoms did not manifest sooner. The patient was a 65-year-old man. He was referred to our department two months after the onset of the paralysis of the lower leg due to progressive swelling of the medial side above the knee. Computed tomography (CT) scan revealed damage to the popliteal artery. A 75×115 mm pseudoaneurysm was noted. We judged that a direct approach to the injured site was difficult, so we performed hematoma removal after hemostasis with a stent graft (SG). Postoperatively, a pool formed in the open pseudoaneurysm, and an infection developed through the wound opening; therefore, we performed popliteal artery vascular bypass and SG removal. The treatment strategy for a popliteal pseudoaneurysm should be determined according to the extent and location of the injury and whether or not there is obstruction. Furthermore, when a large pseudoaneurysm is formed, the treatment of the hematoma is also an issue. It is important to understand the characteristics of the treatment and to choose appropriately.
