Abstract

Endovascular aneurysm repair (EVAR) has been accepted as an alternative to traditional open surgery in selected patients. Despite the minimally invasiveness of this treatment, several complications may occur during or after EVAR. Complications include endoleak, aortic dissection, distal embolism, or iatrogenic injury to the access artery. However, there are few reports on the vascular rupture caused by a molding balloon during EVAR. We report two cases of infrarenal abdominal aortic aneurysms complicated by procedure-related aortic or iliac artery rupture by the molding balloon during EVAR. In our cases, we observed suddenly abrupt increase of the diameter of the endograft during balloon inflation, because we inflated the balloon rapidly. In conclusion, careful attention must be paid during inflation of the molding balloon to prevent vascular rupture.

복부 대동맥류의 혈관 내 치료는 개복수술의 대안으로 인정받고 있다. 복부 대동맥류의 중재적 치료는 비침습적인 치료로서 장점이 있으나, endoleak, 대동맥 박리, 장골 동맥과 같은 access artery의 손상을 포함한 몇 가지 합병증이 알려져 있다. 하지만, 복부 대동맥류의 혈관 내 치료 도중 molding balloon에 의한 혈관 파열에 대해서는 보고된 바가 적다. 이번 증례에서는 복부 대동맥류의 중재적 치료에 의해 발생한 대동맥 파열 1예와 장골동맥 파열 1예를 소개하고 그 원인에 대해 고찰하고자 한다. 이 증례에서 balloon inflation을 너무 급격하게 시행하였기 때문에, balloon inflation 도중에 endo-graft의 직경이 급격히 증가하였고 이로 인하여 혈관 파열이 일어난 것으로 추정된다. 따라서, 복부 대동맥류의 혈관 내 치료시 molding balloon을 inflation할 때는 서서히 inflation하도록 특별한 주의가 요구된다.
