title: CT assessment of abdominal hemorrhage in coagulopathic patients: impact on clinical management.
abstract: BACKGROUND
  To assess how computed tomography (CT) affected clinical management in coagulopathic patients with suspected spontaneous abdominal hemorrhage.
  
  
  METHODS
  Fifty-four patients with coagulopathy underwent CT for possible abdominal hemorrhage. Medical records were reviewed retrospectively for pre-CT management strategy, degree of clinical suspicion for abdominal hemorrhage, CT findings, and post-CT management strategy.
  
  
  RESULTS
  Abdominopelvic CT demonstrated hemorrhage in 31/54 (57%) of patients; 20/54 (37%) of patients had retroperitoneal hemorrhage, 2/54 (4%) had hemoperitoneum, and 9/54 (17%) had hemorrhage confined to the thigh, groin, and/or abdominal wall. CT directly affected clinical management in 28/54 (54%) cases; 17/31 (55%) CT scans that were positive for hemorrhage had a clinical impact versus 11/23 (48%) negative CT scans. This difference was not statistically significant (p = 0.61). CT scans with a higher pretest suspicion for abdominal hemorrhage were more likely to have hemorrhage detected (p = 0.0046) but not more likely to have a clinical impact (p = 0.73).
  
  
  CONCLUSIONS
  CT to assess for abdominal hemorrhage had a direct impact on clinical management in about one-half of coagulopathic patients. Positive and negative CT studies were equally likely to affect management.
