INTRODUCTION: Mesenteric hematoma is a rare condition caused by bleeding localized in the mesenteric vascular tree. This is a first report of spontaneous mesenteric hematoma caused by rivaroxaban.
PRESENTATION OF CASE: The patient was a 71-year-old man who had taken rivaroxaban for paroxysmal atrial fibrillation. He had experienced abdominal pain and diarrhea for the prior 3 days. He had little melena and was referred to our institute. He presented with hypotension on arrival. Computed tomography (CT) revealed a 10 cm mass in the mesentery of the sigmoid colon with extravasation. Active bleeding from the sigmoid colic arteries was embolized with angiography on the day of admission. On the second day, we operated on the patient. We detected 200 mL of bloody ascites accumulated in the abdomen. The serosa of the sigmoid colon was ruptured along the tenia due to the compression of the hematoma in the mesentery. The sigmoid colon was resected and a descending colostomy was reconstructed. Operative and pathological findings did not reveal the cause of bleeding. We finally diagnosed the patient with spontaneous mesenteric hematoma associated with rivaroxaban.
DISCUSSION: Previous reports of mesenteric hematoma with anticoagulant were associated with warfarin. Since rivaroxaban is not affect to the value of prothrombin time (PT) and activated partial thromboplastin time (APTT) and mesenteric hematoma presents non-specific symptoms, it is difficult to diagnose mesenteric hematoma in the patients taking rivaroxaban.
CONCLUSION: It is important to keep in mind that mesenteric hematoma is one of the critical complications in patients taking rivaroxaban.
