目的探讨植入性胎盘的发生率、病因、诊断及治疗。方法回顾性分析1999年1月～2006年12月收治的52例植入性胎盘病例。结果2003年1月～2006年12月植入性胎盘的发生率0.554%(35/6313),较1999年1月～2002年12月的发生率0.191%(17/8893)明显升高(P<0.01)。植入性胎盘在前置胎盘中的发生率为8.564%,明显高于在非前置胎盘中的发生率(0.122%)(P<0.01)。52例患者全部采用手术治疗(保守性手术46例,次全子宫切除术6例)。结论植入性胎盘近年来发生率呈明显上升趋势,前置胎盘患者是发生植入性胎盘的高危人群。
Objective To investigate the incidence of placenta accreta, etiology, diagnosis and treatment. Methods Retrospective analysis of 52 cases of implanted placenta admitted from January 1999 to December 2006. Results The incidence of implanted placenta from January 2003 to December 2006 was 0.554% (35/6313), which was significantly higher than that from January 1999 to December 2002 (0.191%, 17/8893) (P <0.01). The incidence of placenta accreta in the placenta previa was 8.564%, which was significantly higher than that in placenta previa (0.122%) (P <0.01). All 52 patients underwent surgical treatment (conservative surgery in 46 cases, subtotal hysterectomy in 6 cases). Conclusion The incidence of implanted placenta in recent years showed a clear upward trend in patients with placenta previa placenta occurred in high-risk groups.
