Development and validation of a multi-slice CTA-based prediction model for poor outcomes in isolated superior mesenteric artery dissection.

ABSTRACT:

Objective

A prediction model for poor outcomes in patients with isolated superior mesenteric artery dissection (ISMAD) was constructed and validated based on multi-slice spiral CT angiography (MSCTA) imaging features and clinical indicators, aiming to provide a basis for early clinical identification of high-risk patients and formulation of individualized treatment strategies.

Methods

A total of 360 patients with ISMAD who were admitted to our hospital from January 2021 to December 2024 were retrospectively included. They were randomly divided into a training set (n = 252) and a validation set (n = 108) at a ratio of 7:3. The demographic characteristics, clinical symptoms and signs, laboratory test results, and MSCTA imaging features of the patients were collec
