Background  Though injury to the inferior epigastric artery (IEA) is reported to be the most common source of hemorrhagic complications from paracentesis, we wish to present our experience involving deep circumflex iliac artery (DCIA) injuries that in our experience is the artery most frequently injured during paracentesis.    Methods  Sixteen patients with clinically significant hemorrhage following paracentesis were referred to our Interventional Radiology service for trans-catheter embolization. Patterns of hemorrhage from diagnostic cross-sectional imaging and subsequent angiographic findings and management were investigated.    Results  8/16 patients (50%) had angiographic evidence of injury to the DCIA and 4/16 patients (25%) had evidence of injury to the IEA, with two of these patients demonstrating hemorrhage from both the DCIA and IEA; 3/16 patients had injuries to subcostal and/or intercostal arteries; while 3/16 patients had negative angiograms. All patients underwent embolization of the identified injured arteries, and empiric embolization was performed of the DCIA and/or IEA in the three patients with negative angiograms. Fourteen of sixteen patients stabilized post embolization, while two patients required a second embolization procedure to achieve hemostasis; all patients were subsequently discharged home in stable condition.    Conclusion  Both the IEA and the lesser known DCIA need to be considered when performing paracentesis and at subsequent angiography for post paracentesis iatrogenic hemorrhage. Knowledge of both of these at-risk abdominal wall arteries may help minimize hemorrhagic complications from paracentesis.

Post paracentesis deep circumflex iliac artery injury identified at angiography, an underreported complication
