Abstract

Objectives: This study aimed to identify iliac artery characteristics of East Asian patients with abdominal aortic aneurysms (AAAs) and to evaluate the anatomical suitability rates with current iliac branch devices (IBDs).

Methods: This was a single centre, retrospective, cross-sectional study. Patients diagnosed with AAA between 2008 and 2023 were enrolled. Morphological parameters of iliac arteries were measured, and their eligibility for four IBDs (Cook ZBIS, Gore IBE, E-Liac IBD, and G-Iliac IBD) was evaluated according to the manufacturer's latest instructions for use (IFU).

Results: Among 1 144 AAAs observed in the study, 45.5% (n = 521) presented with concurrent common iliac artery aneurysm (CIAA). In total, 304 patients (26.6%) and 371 iliac arteries necessitated internal iliac artery (IIA) reconstruction. The anatomical suitability rates for the Cook ZBIS, Gore IBE, E-Liac IBD, and G-Iliac IBD were 18.9%, 21.8%, 11.9%, and 22.6%, respectively. The E-Liac IBD exhibited a significantly lower anatomical suitability rate compared with the other three devices (p < .001). The primary exclusion criteria of IBDs were: a common iliac artery (CIA) length of < 50 mm for Cook ZBIS (n = 211, 56.9%); an IIA diameter of < 6.5 mm or > 13.5 mm for Gore IBE (n = 177, 47.7%); and a CIA bifurcation diameter of < 18 mm both for E-Liac IBD and G-Iliac IBD (n = 244, 65.8%). A total of 171 patients (46.1%) failed to meet the anatomical criteria for any device, while 120 (32.4%) qualified for one device, 34 (9.2%) for two devices, 36 (9.7%) for three devices, and 10 (2.7%) for all four devices.

Conclusion: A significant proportion of East Asian patients with AAA present with concurrent CIAA, necessitating substantial IIA reconstruction. The IBD techniques show low anatomical suitability rates among the East Asian population, with 46.1% of patients failing to meet anatomical criteria for any IBD based on the manufacturer's IFU.

东亚腹主动脉瘤患者对髂支装置的解剖适应性。

研究目的本研究旨在确定东亚腹主动脉瘤（AAA）患者的髂动脉特征，并评估目前髂支装置（IBD）的解剖适用率：这是一项单中心、回顾性、横断面研究。方法：这是一项单中心回顾性横断面研究，研究对象为 2008 年至 2023 年期间诊断为 AAA 的患者。测量了髂动脉的形态学参数，并根据制造商的最新使用说明（IFU）评估了他们使用四种IBD（Cook ZBIS、Gore IBE、E-Liac IBD和G-Iliac IBD）的资格：在研究观察到的 1 144 例 AAA 中，45.5%（n = 521）的患者同时伴有髂总动脉瘤（CIAA）。共有 304 名患者（26.6%）和 371 条髂动脉需要进行髂内动脉（IIA）重建。Cook ZBIS、Gore IBE、E-Liac IBD 和 G-Iliac IBD 的解剖适用率分别为 18.9%、21.8%、11.9% 和 22.6%。与其他三种器械相比，E-Liac IBD 的解剖适用率明显较低（Gore IBE 的 p 为 13.5 mm（n = 177，47.7%）；CIA 的分叉直径为 1.5 mm）：相当一部分东亚 AAA 患者同时伴有 CIAA，需要进行大量的 IIA 重建。IBD 技术在东亚人群中的解剖适用率较低，根据制造商的 IFU，46.1% 的患者不符合任何 IBD 的解剖标准。

期刊介绍： The European Journal of Vascular and Endovascular Surgery is aimed primarily at vascular surgeons dealing with patients with arterial, venous and lymphatic diseases. Contributions are included on the diagnosis, investigation and management of these vascular disorders. Papers that consider the technical aspects of vascular surgery are encouraged, and the journal includes invited state-of-the-art articles. Reflecting the increasing importance of endovascular techniques in the management of vascular diseases and the value of closer collaboration between the vascular surgeon and the vascular radiologist, the journal has now extended its scope to encompass the growing number of contributions from this exciting field. Articles describing endovascular method and their critical evaluation are included, as well as reports on the emerging technology associated with this field.
