Case report reveals improved outcomes for inferior mesenteric vein thrombosis in an elderly woman with antiphospholipid syndrome, suggesting the importance of early diagnosis.
Inferior mesenteric vein (IMV) thrombosis is a rare but potentially fatal subset of mesenteric venous thrombosis (MVT). We report a 75-year-old woman presenting with epigastric pain, fever, and Escherichia coli bacteremia, found to have isolated Inferior mesenteric vein thrombosis on contrast-enhanced computed tomography. Conservative management with bowel rest, anticoagulation, and antibiotics led to clinical improvement and partial thrombus regression. Subsequent workup revealed antiphospholipid syndrome with associated protein C, S, and antithrombin III deficiencies. This case underscores that early diagnosis and prompt intervention significantly improve prognosis, and highlights the need for heightened clinical awareness of Inferior mesenteric vein thrombosis given its nonspecific presentation and life-threatening potential.
