Abstract

A major concern associated with carotid artery angioplasty and stenting (CAS) is a periprocedural distal cerebral embolization. To prevent distal embolization, embolic protection devices (EPDs) have been developed. However, the risk of cerebral embolism after protected CAS in patents with a vulnerable plaque is controversial and either a silent or a symptomatic stroke can occur despite the use of EPDs. Here, we report a case of a massive cerebral microemboli after a protected CAS using a distal filter EPD for a vulnerable plaque with a lipid rich necrotic core and intraplaque hemorrhage.

경동맥 혈관성형술 및 스텐트삽입술과 관련된 주요 합병증은 시술 도중 발생하는 원위부 뇌색전증으로 이를 방지하기 위해 색전예방장치가 개발되었다. 그러나 취약한 죽상경화반을 가진 환자의 경우 색전예방장치를 사용한 경동맥 혈관성형술 및 스텐트삽입술 후 뇌 색전증의 위험은 논란의 여지가 있으며, 색전예방장치의 사용에도 불구하고 무증상 또는 증상이 있는 뇌졸중이 발생한다. 저자들은 지방이 풍부한 괴사성 핵과 경화반 내 출혈이 있는 취약한 죽상경화반의 원위 필터형 색전예방장치를 이용한 내경동맥의 스텐트 시술 후 발생한 다량의 뇌 미세혈전의 증례를 보고하고자 한다.
