Abstract
Objective: This study compares chronic limb-threatening ischemia disease characteristics and endovascular revascularization outcomes in a multi-ethnic Asian cohort vs their North American counterparts.
Methods: The Society for Vascular Surgery Vascular Quality Initiative (VQI) registry database from the first and currently the only VQI center in Asia was reviewed to identify patients with chronic limb-threatening ischemia who underwent endovascular revascularization between July 2019 and April 2024. Standardized VQI reporting variables were compared against benchmarks derived from all participating centers in North America.
Results: A total of 2862 endovascular revascularization procedures from our center were benchmarked against 129,347 procedures from 406 North American centers. Our cohort had a higher burden of comorbidities (diabetes mellitus, end-stage renal disease, cardiac disease) and presented with more advanced Wound, Ischemia, and foot Infection stages. Our patients had more heavily calcified and longer (14.8 cm vs 6.0 cm) diseased vessels with higher prevalence of multi-level (87% vs 54.6%), infrapopliteal (52.6% vs 38.9%), and inframalleolar (9.6% vs 2.4%) disease. Rates of technical success (92.7% vs 93%) and symptom improvement (39.1% vs 40.4%) were comparable between cohorts. However, 1-year mortality rates (28.9% vs 25.1%) and major amputation rates (13.3% vs 7.8%) were significantly higher.
Conclusions: Short-term outcomes of technical success and symptom relief in our center were comparable to benchmarked North American outcomes despite having a cohort with more diseased vessels, higher Wound, Ischemia, and foot Infection stages, and more comorbidities. However, this cohort fared worse in longer term outcomes of 1-year mortality and major amputation rates. Further studies are required to elucidate the causes to improve these outcomes.
期刊介绍：
Journal of Vascular Surgery ® aims to be the premier international journal of medical, endovascular and surgical care of vascular diseases. It is dedicated to the science and art of vascular surgery and aims to improve the management of patients with vascular diseases by publishing relevant papers that report important medical advances, test new hypotheses, and address current controversies. To acheive this goal, the Journal will publish original clinical and laboratory studies, and reports and papers that comment on the social, economic, ethical, legal, and political factors, which relate to these aims. As the official publication of The Society for Vascular Surgery, the Journal will publish, after peer review, selected papers presented at the annual meeting of this organization and affiliated vascular societies, as well as original articles from members and non-members.
