Abstract
Objective: This study aimed to identify the iliac artery characteristics of East Asian patients with abdominal aortic aneurysms (AAAs) and to evaluate 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. The morphological parameters of the 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 IBD exclusion criteria 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 198 patients (53.4%) failed to meet the anatomical criteria for any device, while 112 (30.2%) qualified for just one device, 26 (7.0%) for two devices, 25 (6.7%) 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. IBD techniques show low anatomical suitability rates among the East Asian population, with 53.4% of patients failing to meet anatomical criteria for any IBD based on the manufacturer's IFU.
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.
