Abstract

Vascular complications following a femoral fracture are rare but can result in serious issues. Several case studies have reported pseudoaneurysms occurring after direct trauma or the insertion of a proximal femoral nail in the case of a proximal femoral fracture. The authors encountered an 85-year-old patient treated with retrograde intramedullary nail fixation for a distal femur fracture and suffered a decrease in the hemoglobin level, swelling, and pain on the 9th day after surgery. The authors initially attributed the temporary hematoma and pain to ordinary postoperative processes. On the 16th day after surgery, a pseudoaneurysm originating from the descending branch of the lateral femoral convolutional artery was diagnosed and treated by percutaneous vascular embolization. After the procedure, the hemoglobin level increased, and the swelling and pain decreased.

대퇴골 골절 이후 발생하는 혈관계 합병증은 드물지만 발생할 경우 심각한 문제를 초래할 수 있다. 근위 대퇴골 골절에서 직접적인 외상 혹은 근위대퇴골 골수 정 고정술 후 발생한 가성동맥류에 대해서는 몇 차례 증례보고가 있었다. 저자들은 85세 여환에서 원위대퇴골 골절에 대하여 역행성 골수 정 고정술 시행 후, 수술 후 9일째부터 혈색소 감소와, 종창, 통증이 발생했던 것에 대해 수술 후 일시적인 혈종 및 통증으로 오인하였다가, 수술 후 16일째가 되어서야 근위 교합 나사 주변부에서 외측 대퇴 회선 동맥의 하행분지에서 기원한 가성동맥류를 진단하였고, 경피적 혈관 색전술을 시행하여 치료 하였다. 시술 후 혈색소 상승 및 종창, 통증 감소 소견을 보이며 회복하였다.
