title: Incidence of postoperative acute renal failure among violence-related cardiovascular trauma patients: a review of our experience in 117 cases.
abstract: BACKGROUND
  The purpose of this retrospective study was to determine the incidence of renal failure and hemodialysis (HD) in postoperative period after cardiovascular surgery associated with trauma.
  
  
  METHODS
  One hundred and seventeen cases of violence-related cardiovascular trauma patients had emergent surgery between 1996 and 2009. Cases were reviewed in three main groups: Cardiac trauma in 11 patients (Group A), vascular trauma in 78 patients (Group B), and cardiovascular trauma in 28 patients (Group C). Postoperative incidence of HD requirements with acute renal failure (ARF) was investigated in these groups of patients postoperatively.
  
  
  RESULTS
  Multiorgan deficiency developed in 10 patients from Group A, in 45 patients from Group B, and in 26 patients from Group C. Overall mortality was 81 cases in 117 patients. Total hospitalization periods were 21 +/- 2, 17 +/- 3, and 27 +/- 1 days for Group A, Group B, and Group C, respectively. HD administrations were indicated in 3 patients in Group A, 41 patients in Group B, and 9 patients in Group C. No statistically significant difference presented in any study parameter between groups.
  
  
  CONCLUSIONS
  Cardiovascular trauma is a common reason for emergent cardiovascular surgery. Postoperative renal failure occurs among these patients in a wide percentage. We strongly advocate a close and detailed follow-up of renal functions in these patients during the hospitalization period and immediate HD at indication.
