초록

지속적 좌측상대정맥은 드문 선천성 흉부 혈관 기형이다. 지속적 좌측상대정맥은 일반적으로 혈역학적 영향이 없지만 몇 가지 유형의 지속적 좌측상대정맥과 동반되는 심장 기형은 임상 증상을 유발할 수 있다. 지속적 좌측상대정맥의 존재는 심장 박동기 또는 중심 정맥 카테터를 배치할 때 왼쪽 쇄골 하 접근을 통한 심장으로의 카테터 삽입을 어렵게 만들 수 있다. 우연히 발견된 지속적 좌측상대정맥을 인식하는 것은 혈관 손상과 같은 합병증을 예방할 수 있다. 또한 지속적 좌측상대정맥과 유사한 위치에 있는 다양한 혈관들을 감별하는 것은 향후 흉부혈관시술을 위해서 필요하다. 이번 임상 화보는 지속적 좌측상대정맥의 다중 검출기 컴퓨터단층촬영 소견을 설명하고 감별이 필요한 다른 혈관들에 대해 요약해 보고자 한다.

Persistent left superior vena cava (PLSVC) is a rare congenital, thoracic, and vascular anomaly. Although PLSVCs generally do not have a hemodynamic effect, several types of PLSVC and some cardiac anomalies may manifest with clinical symptoms. The presence of PLSVC can render catheterization via left subclavian access difficult when placing a pacemaker or central venous catheter. As such, recognizing a PLSVC that is typically incidentally discovered can prevent complications such as vascular injury. Differentiating vessels found in a similar location as PLSVC is necessary when performing thoracic vascular procedures. This pictorial essay explains the multi-detector CT findings of a PLSVC, and provides a summary of other blood vessels that require differentiation during thoracic vascular procedures.
