장골동맥에 국한된 동맥류의 인터벤션 시술 = Interventional Procedures of the Isolated Iliac Arterial Aneurysm

다국어 초록 (Multilingual Abstract)

Purpose: To report the results of treatment isolated iliac arterial aneurysms by interventional procedures.
Materials and Methods: Over a period of 5 years, 7 isolated iliac artery aneurysms (4 in the common iliac artery, 3 in the internal iliac artery) in 7 patients (3 women, 4 men; mean age, 65.7 years) were treated using interventional procedures. The mean aneurysm size was 35 mm (range, 30-45 mm). The common iliac aneurysms were treated using a unilateral stent graft (2 balloon expandable, 2 self-expandable) with coil embolization of the internal iliac artery (n = 3), except for 1 aneurysm that ruptured. Coil embolization alone was performed for aneurysms involving only the internal iliac artery (n = 3).
Results: All patients were treated successfully, except for 1 with an initial remnant of type 2 endoleak. There were no perioperative complications. No leakage or complication occurred at the mean follow-up of 14 months (range 2-29 months). One patient with a ruptured aneurysm died of multi-organ failure during the follow-up period. Three aneurysms had decreased in size on follow-up CT.
Conclusion: Interventional procedures with stent grafting and coil embolization are safe and effective treatments for isolated iliac artery aneurysms.

목적: 장골동맥에 국한된 동맥류를 인터벤션 시술로 치료한 결과에 대하여 보고하고자 한다.
대상과 방법: 지난 5년간 7명의 환자(여자 3, 남자 4; 평균 65.7세)에서 장골동맥을 단독으로 침범한 7예의 장골동맥류를 인터벤션 시술로 치료하였다. 동맥류의 평균 크기는 35 mm(30~45 mm)였다. 4예의 총장골동맥류는 스텐트 그라프트(풍선확장형 2예, 자가확장형 2예)를 동측에 설치하였고 동맥류 파열로 내원한 1명을 제외한 3예에서 내장골동맥의 코일폐색술을 병행하였다. 내장골동맥에만 국한된 동맥류 3예에서는 코일폐색술만으로 치료하였다.
결과: 모든 환자에서 시술은 성공적이었으나 1명에서 2형 endoleak가 남아있었다. 시술과 관련된 합병증은 없었으며 평균 14개월(2~29개월)의 추적기간 중에도 endoleak나 합병증은 발생하지 않았다. 동맥류 파열로 내원한 1명은 추적기간 중 다기관 기능부전으로 사망하였다. 추적 CT에서 3예의 동맥류의 크기가 감소되었다.
결론: 장골동맥에 국한된 동맥류에 대하여 스텐트 그라프트와 코일색전술을 이용한 인터벤션 시술은 안전하고 효과적인 치료법이다.
