Abstract
The observations and information available on stenosis and occlusion of the splanchnic arteries are primarily derived from surgical (1–4) and autopsy (5–7) studies. The clinical problem of splanchnic artery obstruction, however, extends beyond those patients who are either severely symptomatic or those with a fatal course. Undetermined from these studies is the incidence of asymptomatic or atypically symptomatic patients with splanchnic vessel lesions, since these vessels are not routinely palpated during exploratory laparotomy nor routinely described in autopsy reports (8). Knowledge of this incidence is necessary in evaluating the significance of the type and number of splanchnic vessel obstructions and the influence of collateral vessels in relation to the symptoms of intestinal angina. Abdominal arteriography, in contrast to autopsy and surgical studies, offers a unique opportunity to investigate these lesions in an in vivo population and thus to study their potential natural incidence and history.
