초록

허리 통증을 주소로 내원한 63세 남자 환자에게 수술 전 준비로 좌측 쇄골 하 정맥을 통한 중심정맥관 삽입을 했다. 흉부촬영에서 중심정맥관의 카테터 팁이 평상시와는 다른 곳에 위치하여 추후 정맥조영술 및 다중 검출기 컴퓨터단층촬영을 시행하였다. 영상 검사상 왼팔머리정맥이 관찰되지 않았다. 원래의 좌측 경부 및 상지의 정맥 순환은 왼팔머리정맥 대신 늘어난 왼위갈비사이정맥과 부반기정맥을 통해 대정맥으로 이루어졌다. 저자들은 성인 환자에서 증상이 없는 왼팔머리정맥의 부재와 관련한 드문 증례를 보고하고 관련 문헌에 대해 검토하고자 한다.

A 63-year-old male patient was referred for venography of the thoracic venous system and multidetector computed tomography (CT) due to the unusual location of the left subclavian catheter tip. His venogram and CT images showed an absence of the left brachiocephalic vein (LBCV). Instead of through the LBCV, the usual venous circulation of neck and left upper limb was carried out by the engorged left superior intercostal vein (LSIV); this subsequently drained into the accessory hemiazygos vein and then the azygos vein that drains into the superior vena cava. Here, we report a rare case of an incidentally found absence of the LBCV with venous return through the LSIV in an adult patient, and we present a brief review of the relevant literature.
