Iliac Calcium Score thresholds predict cardiovascular and limb-related outcomes in TASC D aortoiliac disease.

ABSTRACT:

Introduction

Extensive lower limb arterial calcification complicates revascularization and is linked to poor outcomes, including limb loss and cardiovascular events. Standardized scoring systems are lacking, particularly in aortoiliac TASC II D lesions. This study evaluated the prognostic value of a CT-based Iliac Calcium Score (ICS) in predicting major adverse limb events (MALE), cardiovascular events (MACE), and all-cause mortality in patients with severe aortoiliac disease.

Methods

In this prospective cohort (2013-2024), 109 patients with TASC II D aortoiliac occlusive disease underwent elective revascularization and preoperative CT angiography. Iliac artery calcification was scored semiquantitatively by morphology, circumference, and lesion length. Patients were stratifi
