Abstract

Orthotopic liver transplantation has become the treatment of choice for patients with end-stage liver disease. Various early or delayed vascular complications, including arterial pseudoaneurysm, thrombosis, or stenosis, and venous stenosis or occlusion, may lead to graft failure. Early detection and prompt management of such complications are essential to achieve successful transplantation and prevent the need for retransplantation. This report presents differentiating points, using computed tomography and digital subtraction angiography findings and measurement of pressure gradient across the stenotic lesion, that require immediate intervention in patients with inferior vena cava stenosis after orthotopic liver transplantation.

뇌사자 간이식은 말기 간질환 환자에서 최우선치료로 시행되고 있다. 간이식 후 가성동맥류 형성, 동맥 혈전증 및 협착, 정맥의 협착 및 폐색 등 다양한 초기 또는 후기 혈관 합병증이 발생할 수 있으며, 이는 이식 실패를 야기할 수 있다. 이러한 합병증을 빨리 발견하고 적절한 치료를 하는 것이 이식 성공을 달성하고 재이식을 방지하기 위해 중요하다. 이 증례 보고에서는 컴퓨터단층촬영 및 디지털감산 혈관조영술 영상 소견과 협착 부위 전후의 압력차 측정을 통해 뇌사자 간이식 후 발생한 하대정맥 협착 환자에서 즉각적인 인터벤션이 필요한 감별점을 제시하고자 한다.
