超声诊断腹主动脉瘤腔内隔绝术后内瘘进展

Progresses of ultrasonography in diagnosis of endoleak after endovascular aneurysm repair

内瘘是腹主动脉瘤腔内隔绝术(EVAR)后最常见的并发症之一,可使动脉瘤增大,最终导致动脉瘤破裂。对EVAR术后患者需要定期随访腹主动脉及支架情况,CTA是目前临床最常用的随访手段。近年来,超声在EVAR术后内瘘的诊断及分型中的作用得到越来越多认可。本文就超声在EVAR术后内瘘的诊断及分型中的进展进行综述。

Endoleak is the most common complication after endovascular aneurysm repair (EVAR). Endoleak can increase the size of the aneurysm and eventually lead to the rupture of aneurysm. The abdominal aorta and stent in patients after EVAR need to be regularly followed up. CTA has been widely used to detect endoleak after EVAR at present. In recent years, the role of ultrasound in detection and classification of endoleak after EVAR has been more and more recognized. The progresses of ultrasonography in diagnosis of endoleak after EVAR were reviewed in this article.
