Abstract:
tomography angiography ( CTA) and T12-S1 vertebral computed tomography three-dimensional reconstruction were selected .The operative win-dows of L1 ~L2 OLIF were observed:the vascular window ,bare window ,psoas major window ,ideal operative window and actual operative win-dow.The operative windows ’ percentage accounted for ideal operative window were calculated ,the actual operative window based on an actual operative window of <1 cm,≥1 cm were statistically analyzed ,and the positions of the left renal artery and renal vein in front of operative window of L1 ~L2 OLIF were observed.Results The actual operative window was <1 cm in 2 cases (3.3%) and ≥1 cm in 58 cases (96.7%).In 58 cases,the difference was significant(P=0.008) in gender and men were more than women.The vascular window,bare win-dow and psoas major window accounted for the ideal operative window by 45%,43%and 12%,respectively ,and the actual operative window accounted for the ideal operative window by 55%.The left renal artery and renal vein's walking planes were at between the middle 1/3 of L1 to up 1/3 of L2 .There were 31 cases (51.7%) of the left renal artery being behind the left renal vein .Conclusion The regional anatomy of the operative window of L1 ~L2 OLIF has its own peculiarities,and not all L1 ~L2 levels are suitable for OLIF.The left renal vessels’ walk-ing planes were in front of L 1 ~L2 .Before L1 ~L2 OLIF surgery,surgeons should analyze the imaging anatomimy through imaging .
