정맥 내 공기 색전은 조영제 주입과 관련된 합병증으로 알려져 있다. 대부분의 경우 색전된 공기의 양이 적고 증상이 없으나 대량의 공기 색전은 치명적일 수 있다. 저자들은 흉부 CT 촬영 중 조영제 주입과 관련하여 발생한 대량의 우심실 내 공기 색전과 보존적 치료로 후유증 없이 회복된 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
A venous air embolism is a complication of various venous access procedures such as contrast-enhanced computed tomography (CECT). Although most cases of iatrogenic venous air embolisms during CECT involve a few milliliters of air and are asymptomatic, a massive venous air embolism can be fatal. We report a case of a massive intraventricular air embolism after CECT with a review of the literature regarding the pathophysiology and treatment of air embolisms.
