  • A persistent proatlantal artery (PA) is rare. We report a type 1 persistent PA originating from the right external carotid artery (ECA). A 78-year-old woman presented with dizziness. Computed tomographic (CT) angiography showed a persistent PA originating from the right ECA. This persistent PA did not pass through the atlas transverse foramen. The extracranial segment of this artery in the atlas transverse process level had a more lateral position than a normal left vertebral artery. CT angiography well demonstrated the relationship with bony structures and the course of this persistent PA. This anomalous artery in our patient presented as an incidental finding. Surgeon should recognize a persistent PA when performing carotid endarterectomy or ligation of the ECA for avoidance of complication.

  • 전환추동맥은 드물게 보고된 태생기 경-기저동맥문합 잔류동맥의 하나이다. 태생 3주경에 발생하는 경-기저동맥문합은 삼차동맥, 귀동맥, 설하동맥, 그리고 전환추동맥으로 이루어지며, 정상인에서는 태생 6주경 전환추동맥을 마지막으로 모두 퇴화된다. 일반적으로 전환추동맥은 주로 내경동맥에서 기원하며 경추 가로돌기구멍을 통과하지 않는 제1형과, 외경동맥에서 기원하여 첫째 경추 가로돌기구멍을 통과하는 제2형으로 나뉘며, 임상적인 증상을 일으키는 경우는 드물다. 그러나 비교적 잘 동반되는 척추동맥의 무형성을 포함한 두개강내 동맥기형이 있을 수 있으며, 이는 경동맥 내막 절제술 및 외경동맥 색전술 등의 시술시 의의가 있어 심도 있는 이해가 필요하다. 이에 저자들은 자기공명혈관조영술로 진단된 제2형 전환추동맥 증례보고와 문헌고찰을 하고자 한다.

  • We present a case of intracranial aneurysm located in the P1 segment of left posterior cerebral artery in the context of tetralogy of Fallot. Complex variations included right aortic arch with abnormal branching. Also, the bilateral vertebral arteries were absent, with a type I persistent proatlantal intersegmental artery of the left side. The aneurysm was treated with endovascular intervention with a Tubridge flow diverter and was noted to be completely cured on 6-month follow-up. We discuss the many considerations in this patient including developmental and modern-era treatment.
