Abstract

A 31-year-old man without respiratory symptoms was transferred to our clinic with incidentally detected small nodular densities in both the upper lung zones on chest radiography. Chest computed tomography and pulmonary angiography demonstrated that the entrance of the right inferior pulmonary vein to the left atrium was completely blocked, and the venous return of the right lower lobe was achieved through the right superior pulmonary vein with a tortuous venous collateral complex in the venous phase. With echocardiography, mild pulmonary hypertension was detected. Here, we present an asymptomatic adult with isolated stenosis of the pulmonary vein with chronic compensation by venous collateral circulation in spite of mild pulmonary hypertension.

호흡기 증세가 없는 31세 남자가 우연히 발견된 양쪽 폐상부에 작은 결절들이 관찰되어 내원하였다. 심초음파에서 경도의 폐고혈압이 확인되었다. 흉부 CT에서 현저한 우상부 폐정맥의 확장이 있었고 우하부 폐정맥은 좌심방과 연결되지 않은 채 무수한 곁순환을 이루고 있었다. 폐혈관조영술에서는 우하부 폐정맥이 좌심방으로 가는 입구가 완전히 막혀 있고 구불구불한 곁순환을 이루며 우상부 폐정맥으로 이어져 좌심방으로 연결되어 있었다. 결론적으로 저자들은 경도의 폐고혈압이 있었지만, 만성적인 보상으로 무증상인 선천성 고립폐정맥협착증을 진단되어 보고하는 바이다.
