Rapid, moderate, or slow bleeding? CT analysis of abdominopelvic active vascular contrast extravasation classes and mortality outcomes.

ABSTRACT:

Objectives

Building on prior findings that active vascular contrast extravasation (AVCE) size is an independent predictor of in-hospital mortality in abdominopelvic hemorrhages, this study aimed to categorize AVCEs using latent profile analysis (LPA) and examine differences in patient characteristics, treatments, and outcomes.

Methods

We retrospectively included consecutive adults with CT-detected AVCE between January 2019 and May 2022. LPA was applied to classify AVCEs based on size-related features, optimizing the number of classes predictive of 24-h and in-hospital mortality. These classes were compared using univariable analysis with post-hoc pairwise comparisons to identify significant differences. Cutoff values for categorization were derived from size parameters and c
