A Nonsurgical Approach to Mesenteric Vascular Disease.

Mesenteric ischemia is a rare disorder, with considerably high morbidity and mortality rates. It can manifest in several ways, including acute mesenteric ischemia, chronic mesenteric ischemia, nonocclusive mesenteric ischemia, mesenteric venous thrombosis, and colonic ischemia. Of these, acute mesenteric ischemia is the most severe form of intestinal ischemia, with a high mortality rate. The mainstay of therapy for mesenteric ischemia is surgical exploration and resection of infarcted bowel; however, medical therapy can play an important adjunctive role. When diagnosed early, before bowel infarction, endovascular therapy can be used as the primary treatment option. Endovascular therapy includes catheter-based thrombolysis, thromboembolectomy, and stenting. Vasodilators also play an important role in the early management of mesenteric ischemia. Anticoagulation is the main form of therapy in mesenteric venous thrombosis.
