Mesenteric Ischemia

Mesenteric ischemia in the acute care setting

“…3,7 Mesenteric venous thrombosis Mesenteric venous thrombosis can occur either acutely or chronically, with the current published literature estimating a range between 2.9% and 18% of acute mesenteric ischemia cases being caused by venous thrombosis. 3,4,6 While advanced age is a risk factor for other causes of acute mesenteric ischemia, mesenteric venous thrombosis is seen more often in younger individuals (those younger than age 50). This is likely due to the existence of those medical conditions that increase the risk of thrombosis-such as a hypercoagulable state or previous thrombosis-or the use of medications that increase risk such as oral contraceptives.…”

“…1 Current literature shows the mortality for acute mesenteric ischemia ranges from 40% to 100%. [2][3][4] Several factors affect mortality including the etiology, such as venous versus arterial or occlusive versus nonocclusive); the segment of bowel involved; the patient' s age; the presence of kidney disease, diabetes, or hypotension; and the occurrence of a delay in identification and treatment. 5 Historically, surgical intervention often involved removal of necrotic bowel and a late stage of disease; mortality remained high despite intervention.…”

“…By the early 20th century, literature on mesenteric vascular ischemia characterizes the diagnosis as having a hopeless prognosis and indicates that treatment is pointless 1. Current literature shows the mortality for acute mesenteric ischemia ranges from 40% to 100% 2-4. Several factors affect mortality including the etiology (for example, venous versus arterial or occlusive versus nonocclusive); the segment of bowel involved; the patient's age; the presence of kidney disease, diabetes, or hypotension; and the occurrence of a delay in identification and treatment 5.…”
