Fractional Flow Reserve to Assess the Functional Severity of Superior Mesenteric Artery Stenosis in the Patients with Isolated Spontaneous Dissection of Superior Mesenteric Artery

Zhenjie Liu

Abstract

Mesenteric ischemia is the main clinical manifestation of spontaneous isolated superior mesenteric artery dissection (SISMAD). But it is difficult to determine the clinical significance of superior mesenteric artery (SMA) stenoses. Fractional flow reserve (FFR) is an index of the functional severity of arterial stenoses, which is calculated from pressure measurements made during arteriography.
