title: [Effects of left renal vein division on postoperative renal function during open repair of abdominal aortic aneurysm].
abstract: OBJECTIVE
  To explore the effects of left renal vein division (LRVD) on postoperative renal function and examine the overall prognosis in patients undergoing open repair of abdominal aortic aneurysm (AAA).
  
  
  METHODS
  Retrospective analyses were conducted for the clinical data of AAA patients with open repair at our hospital from January 2000 to December 2011. They were divided into LRVD (n = 35) and non-LRVD (n = 141) groups. The 30-day mortality, cardio-cerebrovascular complications, pulmonary complications, preoperative and postoperative levels of creatinine and glomerular rate filtration (GFR), aortic cross-clamping time, blood loss volume, intensive care duration and dialysis or continuous renal replacement therapy (CRRT) rate were compared between two groups.
  
  
  RESULTS
  A total of 189 AAA repair were performed. And 13 patients with suprarenal clamping were excluded. The LRVD group had a significant higher proportion of ruptured AAA (48.6% vs 27.7%, P < 0.01), higher 3-day postoperative creatinine (P < 0.01), longer intensive duration (P < 0.05) and decreased 3-day postoperative GFR (P < 0.01). No significant difference existed in 30-day mortality, incidence of major complications, creatinine or GFR at discharge (P > 0.05).
  
  
  CONCLUSIONS
  LRVD during open surgery of AAA has no effect on the postoperative mortality and renal function.
