Abstract
The aim of this study was to evaluate the current management of acute mesenteric ischemia secondary to thrombotic or embolic occlusion of visceral vessels in a community teaching hospital. Between October 1997 and July 2000, a review of all hospital discharges revealed 83 patients with a discharge diagnosis of “acute vascular insufficiency-intestine.” Among these 83 patients, 22 cases of acute mesenteric ischemia were confirmed. Management of these 22 patients was divided into 2 groups for analysis. In Group A, 14 patients were aggressively treated with visceral angiography (n = 10), visceral artery bypass (n = 8), visceral embolectomy (n = 4), and bowel resection (n = 7). In 8 of 14 of these patients, surgical intervention occurred in less than 24 hours from presentation. In Group B, 8 patients were managed with supportive care because of advanced age (mean age = 86 ±7 years), comorbid conditions, or patient and family preference. Postoperative morbidity in Group A consisted of cardiac events (n = 3), pulmonary insufficiency (n = 5), and prolonged gastrointestinal tract dysfunction (n = 3). Twelve of 14 patients in Group A survived and were discharged, whereas only 2 of 8 patients in Group B survived and were discharged from the hospital. Although the literature suggests that there can be a significant delay in the diagnosis and treatment of acute mesenteric ischemia, the early recognition and aggressive treatment of acute mesenteric ischemia resulted in a good survival rate. Supportive management of very elderly and debilitated patients needs to be considered on a case-by-case basis. Although the outlook for such patients is dismal, survivors are possible as demonstrated by this series.
