Placenta accreta is a rare and potentially life-threatening complication of pregnancy characterized by abnormal adherence of the placenta to the uterine wall. A previously scarred uterus or an abnormal site of placentation in the lower segment is a major risk factor. The aim of this study was to investigate the change in the incidence of placenta accreta and associated risk factors along four decades, from the 1970s to 2000s, in a tertiary south Italian center. We analyzed all cases of placenta accreta in a sample triennium for each decade. The incidence increased from 0.12% during the 1970s, to 0.31% during the 2000s. During the same period, cesarean section rates increased from 17 to 64%. Prior cesarean section was the only risk factor showing a significant concomitant rise. Our results reinforce cesarean section as the most significant predisposing condition for placenta accreta.
胎盘植入是一种罕见的、可能危及生命的妊娠并发症，其特征是胎盘异常附着于子宫壁。既往有剖宫产史或胎盘在下段异常着床是主要危险因素。本研究旨在调查意大利南部一家三级中心在过去四十年（20 世纪 70 年代至 21 世纪 00 年代）中胎盘植入的发病率及相关危险因素的变化。我们分析了每个十年的一个样本三年期内所有胎盘植入病例。发病率从 20 世纪 70 年代的 0.12%上升到 21 世纪 00 年代的 0.31%。同期剖宫产率从 17%上升到 64%。既往剖宫产是唯一显示显著伴随性上升的危险因素。我们的结果强调了剖宫产是导致胎盘植入的最重要的诱发因素。
