Abstract

A 53-year-old woman presented with dyspnea. She had undergone extended thymectomy for an invasive thymoma two months prior. CT revealed numerous small nodules in the lung. After that, she deteriorated owing to acute respiratory distress syndrome (ARDS), and the vascular surgeon planned veno-venous extracorporeal membrane oxygenation (ECMO). During percutaneous cannulation through the left femoral vein, a vascular injury was suspected, and the patient's vital signs became unstable. Diagnostic angiography showed a ruptured left common iliac vein, and the bleeding was stopped by placement of a stent-graft. May-Thurner syndrome was diagnosed on abdominal CT. Here, we report a rare case of ECMO-related vascular injury in a patient with an unrecognized anatomical variant, May-Thurner syndrome.

52세 여자 환자가 호흡곤란을 주소로 내원하였다. 환자는 2개월 전에 침습성 흉선종으로 광범위 흉선절제술을 받았다. 전산화단층촬영에서는 양측 폐에 수많은 소결절들이 발견되었다. 급성 호흡곤란 증후군이 악화되어 혈관외과의는 정맥-정맥 체외막산소공급(extracorporeal membrane oxygenation; 이하 ECMO)을 계획하였다. 왼쪽 대퇴동맥을 통해 경피적 삽관술을 시행하는 도중에 혈관외과의는 혈관 손상을 의심하였고 환자의 활력 징후가 불안정해졌다. 8일 전에 촬영한 복부 컴퓨터단층촬영에서 May-Thurner 증후군이 있었고, 이후 시행한 혈관조영술에서 좌측 총장골정맥의 파열이 발견되어 stent-graft를 삽입하여 출혈을 멈추었다. 8일 전 시행된 복부 전산화단층촬영을 확인해 보니 May-Thurner 증후군이 있었다. 이에 May-Thurner 증후군 환자에서 ECMO 삽관으로 인한 혈관 손상이 발생하여 스텐트 삽입술을 시행하였던 드문 증례를 보고하고자 한다.
