Abstract

We present a rare case demonstrating successful endovascular management of an arterioureteral fistula involving the abdominal aorta. Arterioureteral fistulas are rare but life-threatening, with mortality rates ranging from 7% to 23%. Early recognition and prompt management are essential for preventing catastrophic consequences, including hypovolemic shock. However, recognition of an arterioureteral fistula requires a high index of clinical suspicion due to its rarity and the lack of a sensitive diagnostic method. Arterioureteral fistulas could be induced by traumatic events in patients who have a history of pelvic surgery, radiation, and prolonged placement of a ureteral stent. Endovascular stent graft placement could be a valid treatment option for arterioureteral fistulas involving the abdominal aorta.

저자들은 복부 대동맥에 발생한 동맥-요관루를 혈관 내 접근을 통해 성공적으로 치료할 수 있었던 드문 증례를 보고하는 바이다. 동맥-요관루는 극히 드물지만, 사망률이 7~23%에 이르는 치명적인 질환이다. 저혈량쇼크와 같은 치명적 합병증을 예방하기 위해서는 조기 진단과 함께 즉각적인 치료가 필수적이다. 하지만 질환 자체가 희귀하고 민감도가 높은 검사 방법이 없기 때문에, 진단을 위해서는 높은 수준의 임상적 의심이 반드시 필요하다. 복강 내 수술, 방사선 치료 및 요관 스텐트의 장기 설치 등의 특징적인 과거력을 가진 환자에서 외상적 사건이 동맥-요관루 발생의 촉발 요인이 될 수 있다. 복부 대동맥에 발생한 동맥-요관루 환자에서도 혈관 내 인조혈관 스텐트의 삽입은 효과적인 치료 방법이다.
