Despite being widely used for several years, the endovascular aortic repair (EVAR) of a thoracoabdominal aneurysm (TAAA) remains challenging, particularly the revascularization of the abdominal aortic visceral branches. A 66-year-old male was admitted to hospital with abdominal bloating and pain. Computed tomographic angiography (CTA) confirmed a Crawford type III TAAA from the distal descending aorta to the suprarenal abdominal aorta that involved the celiac axis, accompanied with an occlusion of the left subclavian artery. Fenestrated-EVAR was performed successfully and 1 week later CTA showed a type III endoleak, which had resolved 3 months later, without stent migration or visceral artery occlusion. In this present case, the surgeons preferred to perform the procedure in three surgical stages, postponing the deployment of a covered stent in the CA fenestration to provide additional time for the development of collateral circulation to the spinal cord as a possible means of preventing postoperative paraplegia.
尽管血管腔内主动脉修复术(EVAR)已广泛应用多年,但胸腹主动脉瘤(TAAA)的血管腔内修复术仍然具有挑战性,尤其是腹主动脉内脏分支的血运重建。一名66岁男性因腹胀和腹痛入院。计算机断层血管造影(CTA)证实为从降主动脉远端至肾上腺上腹部主动脉的克劳福德III型TAAA,累及腹腔干,同时伴有左锁骨下动脉闭塞。成功实施了开窗式EVAR,1周后CTA显示III型内漏,3个月后内漏消失,未出现支架移位或内脏动脉闭塞。在本病例中,外科医生倾向于分三个手术阶段进行手术,将覆膜支架在腹腔干开窗处的植入推迟,以便为脊髓侧支循环的建立提供额外时间,作为预防术后截瘫的一种可能手段。
