The morphological pathogenesis of isolated superior mesenteric artery dissection.

ABSTRACT:

Background

Isolated superior mesenteric artery dissection (ISMAD) is a rare arterial disease, and its exact cause is still not well understood. This study aimed to investigate the potential role of anatomical factors in the development of ISMAD.

Methods

This case-control study included patients diagnosed with ISMAD via computed tomography angiography from two major medical centers in China. An equal number of age-sex and body mass index matched patients without aortic and superior mesenteric artery disease were selected as controls. Several anatomical parameters were compared between the ISMAD group and the control group. Significant parameters were identified through univariate and multivariate analyses, and models were evaluated using receiver operating characteristic (ROC
