一体式开窗型腔内移植物腔内隔绝治疗肾周腹主动脉瘤

目的探讨一体式开窗型腔内移植物腔内隔绝治疗肾周腹主动脉瘤的可行性。方法1例64岁男性并存严重冠状动脉狭窄的肾周腹主动脉瘤患者,根据术前薄层CT精确测量数据,设计相应的一体式开窗型腔内移植物。在全身麻醉及数字减影血管造影（DSA）监视下应用此一体式开窗型腔内移植物隔绝腹主动脉瘤,且双侧肾动脉内各置人了一覆膜球囊扩张支架。结果术后即时DSA造影肠系膜上动脉、双肾动脉及左髂内动脉通畅,瘤腔无内漏,术后肌酐较术前略有下降。术后10d复查三维螺旋CT血管造影显示一体式开窗型腔内移植物形态良好,无扭曲、移位、脱节,无内漏,肠系膜上动脉、双肾动脉及左侧髂内动脉通畅、显影良好。结论应用个体化的一体式开窗型腔内隔绝术治疗肾周腹主动脉瘤是可行的。

Endovascular exclusion of juxtarenal abdominal aortic aneurysm with one-piece customized fenestrated endovascular stent-graft

OBJECTIVE: To evaluate the technical feasibility of juxtarenal abdominal aortic aneurysm (AAA) repair with fenestrated endovascalar stent-graft METHODS: A 64-year-old male was diagnosed with juxtarenal AAA with severe coronary artery stenosis, fenestrations was customized according to precise helical CT data to accommodate visceral and renal arteries. Under general anesthesia and dynamic supervision of digital subtraction angiography (DSA), juxtarenal AAA was excluded with the customized fenestrated stent-graft and balloon expandable mini stent-grafts were deployed into bilateral renal arteries respectively. RESULTS: After operation, DSA showed the patency of the super mesenteric artery, bilateral renal arteries and left hypogastric artery, no endoleak was found. The serum creatinine decreased slightly after operation. CT angiography revealed favorable morphology of the stent-graft without tortuosity, migration, disjoint and endoleak 10 days after the operation and patency of super mesenteric artery, bilateral renal arteries and left hypogastric artery. CONCLUSIONS: The placement of customized fenestrated endovascular stent-graft is a feasible option for juxtarenal AAA.
