The chimney graft (CG) technique can be a useful alternative in treating aortic aneurysms with challenging anatomy, regarding the proximal sealing zone. We describe the case of a patient who developed a type Ia endoleak after chimney endovascular aneurysm repair for a juxtarenal AAA and underwent a proximal CG reconfiguration and implantation of an aortic cuff. The crossing configuration of the CGs should be avoided as it may compromise the circumferential apposition of the endograft and impede the thrombosis of the perigraft gutters. A proximal reconfiguration of the CGs, in case of type Ia endoleak is a useful option. The long-term efficacy of this option should be evaluated by meticulous follow-up.
就近端密封区而言，烟囱移植物（CG）技术在治疗解剖结构复杂的主动脉瘤方面可能是一种有用的替代方法。我们描述了一例患者，该患者在接受近肾型腹主动脉瘤的烟囱式血管内动脉瘤修复术后出现Ia型内漏，并接受了近端CG重新构型及主动脉袖带植入术。应避免CG的交叉构型，因为它可能会损害腔内移植物的圆周贴合，并阻碍移植物周围沟内的血栓形成。对于Ia型内漏，CG的近端重新构型是一种有用的选择。该选择的长期疗效应通过细致的随访进行评估。
