Development of a scoring system to predict endovascular crossing of femoropopliteal artery chronic total occlusions: the endo VAscular CROSsing score for chronic total occlusions (EVACROSS-CTO).

Objectives: To develop a predictive score for the prediction of successful endovascular crossing in femoropopliteal artery chronic total occlusions (CTOs).

Methods: In this retrospective study, 84 patients were divided 70%:30% into a training and a testing cohort. Parameters such as cap morphology, side branches, bridging collaterals, flush occlusion, and length were derived from preprocedural CT angiography.

Endovascular treatment of upper limb phlegmasia cerulea dolens in a hemodialysis patient.

Phlegmasia cerulea dolens (PCD) is a rare but limb-threatening complication of deep vein thrombosis. A 72-year-old hemodialysis male patient presented with upper limb PCD. The patient underwent hemodialysis via a permanent hemodialysis central venous catheter (HD-CVC) while a new brachial-cephalic AVF was created 1 month ago.

Utility of Dual-Energy Computed Tomography in lesion characterization and treatment planning for peripheral Chronic Total Occlusions: A comprehensive analysis of crossing difficulty.

Purpose: To investigate whether Dual-Energy Computed Tomography (DECT) could be useful in the lesion characterization and endovascular treatment planning of symptomatic patients with peripheral arterial disease (PAD) due to Chronic Total Occlusions (CTO).

Materials And Methods: Between 2018 and 2022, 60 symptomatic patients (52 male, age 71 years) with peripheral arterial CTO underwent DECT angiography before percutaneous endovascular treatment. Patients were classified, according to guidewire crossing difficulty into four categories, which were subsequently correlated with DECT values, including Dual Energy Index (DEI) and Effective Z (Zeff).

Technical challenges during emergent endovascular aneurysm repair with the ALTO system.

Introduction: Ruptured abdominal aortic aneurysms (AAAs) pose an immediate threat for patient's life and endovascular repair (EVAR) is currently the preferred treatment modality in the presence of suitable anatomy. This is determined based on the requirements of each endograft as described in the instructions for use (IFU). The new ALTO system (Endologix, Irvin, CA, U.
