title: Time limits for intestinal ischemia and congestion: an experimental study in rats.
abstract: We investigated to determine the time limits for intestinal ischemia and congestion. The experimental models were produced by clamping both ends and the intended feeder vessels of an approximately 1-cm length of rat jejunum. The results showed that in arteriovenous occlusion, the time required for the recovery rate to reach 50% was 7.03 hours. The time required for the recovery rate to reach 50% was 6.81 hours when arterial occlusion alone was performed and 3.70 hours when venous occlusion alone was performed. The difference between the two was statistically significant (p < 0.01). Consequently, it was found that the degree of intestinal damage due to venous occlusion was greater than the damage resulting from arteriovenous and arterial occlusion.
