Purpose: To evaluate the etiology of unusual manifestation of hemoperitoneum and the efficacy of transcatheter arterial embolization (TAE). Materials and methods: A retrospective review of patients at three hospitals was performed. A total of 12 patients (M:F = 5:7, mean age: 48) had massive hemoperitoneum without evidence of an intramuscular hematoma on CT (n = 10) or US (n = 2) after injury to the abdominal wall. The patients underwent TAE. The etiology of iatrogenic injury to the abdominal muscular arteries and the effectiveness of embolization were evaluated. Results: Among 12 patients, 11 patients had injuries to the inferior epigastric artery (IEA) and one patient had an injury to the deep circumflex iliac artery (DCIA). The causes of the injuries were: paracentesis (n = 6), open laparotomy (n = 4), removal of a CAPD catheter (n = 1), and surgical drain (n = 1). The TAE was successfully performed in all patients. Over 10 days of follow-up after the embolization, all patients were stabilized hemodynamically. Conclusion: Injury to the IEA or DCIA should be considered as a possible source of hemoperitoneum even in patients with no evidence of an intramuscular hematoma after injury to the superficial arteries of the abdominal wall. In addition, such injuries can be treated successfully using TAE.
