Malignant Thrombi of Inferior Vena Cava from Renal Cell Carcinoma -4 cases reports-

신세포암에 의한 하대정맥 악성 혈전 -치험 4례-

Abstract

Renal cell carcinoma involves the inferior vena cava(IVC) in approximately 5-10% of the patients. Presently surgical extirpation is the only form of therapy that can result in cure. Circulatory arrest with cardiopulmonary bypass is an operative technique that recently has been used to assist in resection of tumors that extend into the vena cava above the level of hepatic veins. We performed removal of tumor thrombi of IVC in 4 patients. All of them who had the renal cell carcinormas with infrahepatic vena caval extension were performed by standard surgical technique without cardiopulmonary bypass. But in one patient, inferior vena caval thrombectomy was done using circulatory arrest because of the recurred extension of the tumor thrombi within the vena cava above the insertion of the hepatic vein. All patients were recovered without any significant problems.

신세포암은 환자의 약 5∼10%에서 하대정맥을 침범한다. 이러한 경우 수술적으로 함께 제거하는 것이 가장 좋은 치료로 되어있다. 최근에는 간정맥 유입로 상부에 위치한 하대정맥내의 종양 혈전 제거술의 경우 체외 순환을 통한 순환 정지 방법이 사용되고 있다. 본 교실에서는 근치적 신적출술과 함께 하대정맥내의 종양 혈전 제거술을 4례 치험하였다. 모든 환자에서 간정맥이하의 하대정맥 혈전으로 체외 순환의 도움 없이 일반적인 방법으로 시행되었으나, 그 중 한 환자에서 간정맥의 유입로보다 상부에 위치한 하대정맥혈전이 재발되어 순환정지후 혈전제거술을 시행하였다. 네 명의 환자 모두 특별한 문제없이 회복되었다.
