Abstract

The levoatriocardinal vein is an uncommon pulmonary venous abnormality that connects the left atrium or pulmonary vein with the systemic vein. It is distinct from partial anomalous pulmonary venous return in that the former forms a connection with the left atrium through the normal pulmonary vein whereas the latter involves pulmonary venous drainage to the systemic vein. Herein, we describe a case of the levoatriocardinal vein initially misdiagnosed as a pulmonary arteriovenous malformation using chest radiography and chest CT. The levoatriocardinal vein combined with pulmonary venous varix was confirmed using pulmonary angiography. To the best of our knowledge, this unusual coexistence of the levoatriocardinal vein and pulmonary venous varix has not been reported in English literature.

Levoatriocardinal 정맥은 폐정맥 기형의 드문 형태로, 좌심방 혹은 폐정맥과 체정맥을 연결해 주는 구조이다. 이는 폐정맥이 체정맥으로 연결되는 기형을 뜻하는 부분 폐정맥 환류 이상과 구분되는데, Levoatriocardinal 정맥은 정상 폐정맥을 통한 좌심방과의 연결성이 있다는 차이점이 있다. 저자들은 폐정맥정맥류가 흉부 엑스선 및 전산화단층촬영에서 동정맥기형으로 오인되었던 증례를 보고하고자 하며, 이는 혈관조영술을 통해 폐정맥정맥류와 동반된 Levoatriocardinal 정맥으로 진단된 경우이다. 이러한 폐정맥정맥류를 동반한 Levoatriocardinal 정맥을 보이는 증례는 영문 문헌상 보고된 바 없기에 이를 보고하고자 한다.
