[Objective]To evaluate the complications of anteroinferior psoasoblique lateral interbody fusion(AIP-OLIF)under direct vi-sion and exposure technique.[Methods]A retrospective study was conducted on 143 patients who received AIP-OLIF from April 2017 to August 2022.The complication and follow-up data were evaluated.[Results]All patients had operation performed successfully with opera-tion time of(238.5±87.7)min,and intraoperative blood loss of(104.1±116.4)ml.Complications in total occurred in 39 patients,accounted for 19.6％.Intraoperative complications occurred in 12 cases(8.4％),including segmental artery injury in 2 cases,peritoneal injury in 2 cas-es,pleural injury in 2 cases,dural injury in 1 case and endplate injury in 5 cases.Early postoperative complications occurred in 12 patients(8.4％),including 6 patients had pain and numbness in the front of the left thigh on the 1st day after surgery,and 6 patients had mild iliopsoas muscle weakness and quadriceps muscle weakness after surgery,whereas all of them recovered to normal at 1-month follow-up.As time went during follow-up period lasted for(14.8±4.3)months,the VAS score and ODI score were significantly decreased(P＜0.05),while JOA score was significantly increased(P＜0.05).In 15 patients(10.5％),the fusion device subsidence was found in images one year after the opera-tion,all of which remained grade 0 subsidence.[Conclusion]AIP-OLIF can still cause intraoperative and postoperative complications,which should be paid attention to.
