Introduction and importance: One of the rare complications of polycystic ovarian syndrome (PCOS) treated with combination contraceptives is venous thrombosis. However, there is currently no information on intestinal necrosis and portal venous thrombosis in polycystic ovary syndrome patients, and diagnosis is frequently delayed in these situations.
Clinical presentation: We report a case of a 30-year old female patient who experienced a sudden onset of rectal bleeding and severe abdominal pain. Superior mesenteric vein thrombosis was detected with Doppler ultrasonography. Right portal vein thrombosis was discovered on contrast-enhanced tomography of the abdomen; it was treated with enoxaparin sodium without improvement. A colonoscopy was then conducted; it revealed a distal descending colon with proximal sigmoid colon ischemia alterations. During a laparoscopic, ischemic portion were removed. On follow-up after two weeks, the patient was still on enoxaparin sodium (80 mg twice daily) in good general condition.
Clinical discussion: Portal vein thrombosis (PVT) and Superior mesenteric venous thrombosis (MVT) are rare forms of venous thrombosis and unusual conditions. Superior MVT related to hormonal contraception and PCOS is uncommon. To best of our knowledge, here we report the first case of PCOS presented with acute intestinal ischemia related to MVT.
Conclusion: Except for the correlation between PCOS and the use of combination contraceptives, no predisposing factor for portal vein thrombosis was found. Our case report indicates the need for clinicians to consider acute intestinal ischemia in patients with polycystic ovarian disease who have acute abdominal pain and atypical site of thrombosis.
