Abstract:
To study the incidence of atherosclerotic involvement of the mesenteric ar teries, autopsies were performed on 47 randomly chosen cadavers that were fifty years old or older. The study encompassed: (1) postmortem angiogram; (2) dissection and macroscopic assessment of the main vessels and any possible col laterals ; and (3) a microscopic grading of the cross-sectional area of the proxi mal 2 cm of the mesenteric arteries. There was a statistically significant preponderance of stenosis among males (83% vs females 67%). The superior mesenteric artery (SMA) had a higher incidence of narrowing (85%) than either the inferior mesenteric artery (IMA) (72%) or the celiac artery (CA) (64%). High-grade stenosis ( 〉 50% of the lumen involved) was most common in the IMA (28%), followed by the SMA (17%) and the CA (11%) . Despite a high incidence of stenosis, a retrospective review of patient charts did not reveal any convincing reports of abdominal complaints. Moreover, only 1 case had dilated collaterals.
