INTRODUCTION: Spontaneous retroperitoneal hemorrhage is a rare adverse outcome of therapeutic anticoagulation, typically resulting from venous bleeding and treated by reversal of anticoagulation. We present a case with an arterial source resulting in abdominal compartment syndrome.
CASE PRESENTATION: A 57 year old man with severe valvular heart disease was admitted with pneumonia and decompensated biventricular failure. Therapeutic anticoagulation with enoxaparin was initiated for a right internal jugular venous thrombus. Three days later, left flank pain and hypotension developed and hemoglobin dropped significantly. CT of the abdomen revealed a large left retroperitoneal hematoma. Rapidly progressive hypotension despite resuscitation led to PEA arrest. Following resuscitation, elevated airway and bladder pressures belied the presence of abdominal compartment syndrome. Emergent decompressive laparotomy was performed and a 14x10 cm space-occupying lesion consistent with rapidly expanding retroperitoneal hematoma was noted. Massive transfusion was required and reversal of anticoagulation was attempted with tranexamic acid. CT angiogram identified an arterial blush within the hematoma. The bleeding source was identified at angiography as a lumbar vertebral artery branch. Transcatheter arterial embolization of the culprit vessel was successfully performed. The patient then returned to OR for evacuation of the hematoma and staged closure of the abdomen.
DISCUSSION: Transcatheter embolization is widely accepted in the management of traumatic retroperitoneal hemorrhage but rarely employed in spontaneous hemorrhage. Several series of spontaneous arterial retroperitoneal hemorrhages have been reported; treatment with transcatheter embolization was generally successful.
CONCLUSIONS: An arterial source must be sought in any spontaneous retroperitoneal hemorrhage causing abdominal compartment syndrome, as venous sources should tamponade before exceeding abdominal perfusing pressure. We recommend a multidisciplinary approach to life-threatening spontaneous hemorrhage including interventional radiology, general and/or vascular surgery, critical care, and the blood bank.
