Abstract

Carotid stump, the blind remnant of an occluded internal carotid artery, can be a potential source of microemboli, and warrants its exclusion from the vascular lumen to prevent the recurrence of a microembolism. In a 69-year-old male with a symptomatic carotid stump and acute angle between left common carotid artery and aortic arch, a 7-Fr. shuttle sheath was scarcely placed into the left carotid artery but the 7-mm-diameter stent-graft-loading balloon could not be inserted into the 7-Fr. shuttle sheath. With the mounting a stent graft over a 5-mm balloon, the balloon-expandable stent graft was unfolded. The self-expandable stent was placed over the stent graft, and an 8-mm balloon was subsequently expanded. Self-expanding stenting can be useful for troubleshooting in a case of device incompatibility coming from the different calibers of the external and common carotid arteries for the successful exclusion of a symptomatic carotid stump.

목동맥 그루터기는 속목동맥이 막히고 남은 자루모양의 구조로 미세색전의 잠재적인 근본 원인이 될 수 있다. 따라서 재발하는 미세색전증을 예방하기 위해 이를 혈관내벽으로부터 차단할 필요가 있다. 유증상 목동맥 그루터기를 가진 69세 남자에서 왼쪽 일반목동맥과 대동맥궁 사이의 각도가 예각을 이루어, 7 프렌치 왕복덮개를 왼쪽 목동맥에 간신히 설치하였으나 7 mm 직경의 인조혈관 스텐트를 얹은 풍선도관이 7 프렌치 왕복덮개 내로 들어가지 못하였다. 5 mm 풍선도관 위에 인조혈관 스텐트를 얹은 다음, 풍선팽창성 인조혈관 스텐트를 설치하였다. 순차적으로 인조혈관 스텐트 위에 자가팽창성 스텐트를 설치하고, 8 mm 풍선을 확장시켰다. 유증상 목동맥 그루터기를 차단하고자 할 때, 바깥목동맥과 일반목동맥의 직경 차이로부터 비롯된 기구의 부적합성이 문제가 될 수 있으며, 이때 부가적인 자가팽창성 스텐트 설치로 이 문제를 해결한 경험을 보고하고자 한다.
