摘要

Background: The effect of left renal vein division (LRVD) during open surgery (OS) for pararenal and juxtarenal abdominal aortic aneurysm (P/JRAA) on postoperative renal function remains controversial, so we focused on chronic renal decline (CRD) and separately examined renal volume as a surrogate index of split renal function. Methods?and?Results: The 115 patients with P/JRAA treated with OS from June 2007 to January 2017 were reviewed: 26 patients without LRVD were matched to 27 patients with LRVD according to preoperative chronic kidney disease (CKD) stage and proximal clamp sites. The effect of LRVD on CRD was investigated by a time-to-event analysis. During a median follow-up of 23.5 months, CRD occurred in 5 patients with LRVD and in 4 patients without LRVD. Comparison of freedom from CRD showed no significant difference between the matched groups (P=0.870). The separate renal volumes were evaluated before surgery and at 1 and 2 years of follow-up using CT images from 18 patients with LRVD. At 2 years, the mean renal volume had decreased by 15% in the left kidney and by 9% in the right kidney (P=0.052 and 0.148, respectively), but the left-to-right renal volume ratio showed no significant change (P=0.647). Conclusions: LRVD had no significant effect on CRD or left renal volume relative to the right renal volume for up to 2 years.
