Key result
Adequate perfusion of the small bowel as measured by xenon clearance was maintained until an 80% reduction of superior mesenteric artery flow (beyond 80 ± 10 ml/min).
Intestinal tissue perfusion is maintained until superior mesenteric artery flow is reduced by 80%, demonstrating significant autoregulatory or compensatory capacity.

Reproducible xenon clearance measures jejunal perfusion during aortic occlusion; leaves open clinical validation in mesenteric ischemia.
Samuel E. Wilson (1975) studied Intestinal blood flow. Reduction of superior mesenteric artery flow via partial aortic occlusion was evaluated on Tissue perfusion measured by xenon Xe 133 clearance rates. Adequate perfusion of the small bowel as measured by xenon clearance was maintained until an 80% reduction of superior mesenteric artery flow (beyond 80 ± 10 ml/min).
