Abstract

Abdominal aortic aneurysms can constitute a therapeutic challenge in several anatomical scenarios, making endovascular treatment more complex. A juxtarenal abdominal aortic aneurysm (JR-AAA) is defined by the absence of a proximal landing zone in the infrarenal segment and, therefore, techniques must be used to obtain an adequate neck for fixing the endoprostheses without provoking occlusion of renal arteries and visceral branches. The parallel grafts technique, physician-modified stent-graft, industry customized endoprostheses, and off-the-shelf branched endoprosthesis are techniques used in abdominal aneurysms with inadequate proximal neck, but each technique has its indications, limitations, and risks. In this therapeutic challenge, we present a case of urgent endovascular treatment of a JR-AAA using a parallel grafts technique, with good medium-term results, and discuss the therapeutic options.

使用并行移植物技术对并隔动脉瘤进行紧急血管内治疗。
腹主动脉瘤在多种解剖情况下都会对治疗构成挑战,从而使血管内治疗变得更加复杂。肾下段腹主动脉瘤(JR-AAA)的定义是没有近端着床区,因此必须使用各种技术来获得足够的颈部以固定内支架,同时不引起肾动脉和内脏分支的闭塞。平行移植物技术、医生改良支架移植物、工业定制的内膜假体和现成的分支内膜假体是用于近端颈部不足的腹部动脉瘤的技术,但每种技术都有其适应症、局限性和风险。在这一治疗难题中,我们介绍了一例使用平行移植物技术对 JR-AAA 进行紧急血管内治疗的病例,取得了良好的中期效果,并讨论了治疗方案。
