目的探讨该院剖宫产术后子宫瘢痕妊娠（CSP）的发生及临床诊治变化特点。方法回顾性分析该院2008年1月-2014年12月诊治的268例CSP的临床资料。结果7年间CSP发生占同期异位妊娠的比率由2008年的1．14％上升到2014年的5．83％，呈逐年上升的趋势，差异有统计学意义（趋势r=5．252，P〈0．05）；年龄≥35岁患者的比率由7．14％上升到30．65％，呈逐年上升趋势，差异有统计学意义（趋势x2=4．124，P〈0．05）；在孕7周内获得早期诊断的患者比率逐年增加，但差异无统计学意义（趋势x2=3．631，P〉0．05）；误诊率由63．64％下降至14．52％，呈逐年下降趋势，差异有统计学意义（趋势x2=4．130，P〈0．05）；开腹手术由45．45％下降至6．45％，呈逐年下降趋势，差异有统计学意义（趋势x2=4．134，P〈0．05）；子宫动脉栓塞（UAE）＋清宫术由18．18％上升到62．90％，呈逐年上升趋势，差异有统计学意义（趋势x2=5．288，P〈0．05）。结论CSP发生率升高，获得早期诊断的患者比率增加，误诊率下降，介入治疗比率升高。

Objective To explore the occurrence and change characteristics of clinical diagnosis and treatment of cesarean scar preg- nancy （CSP） after cesarean section in the hospital. Methods The clinical data of 268 CSP patients in the hospital from January 2008 to December 2014 were analyzed retrospectively. Results From 2008 to 2014, the percentage of,CSP in ectopie pregnancy increased from 1.14% in 2008 to 5.83% in 2014, showing an increasing trend year by year, there was statistically significant difference（x2trend = 5. 252, P〈 0.05） ; the percentage of patients aged 35 years old or more than 35 years old increased from 7. 14% ＇in 2008 to 30. 65% in 2014, showingan increasing trend year hy year, there was statistically significant difference （x2trend= 4. 124, P〈0. 05 ） ; the percentage of early diagnosis i within 7 gestational weeks increased year by year, but there was no statistically significant difference （x2trend = 3.631, P〉0. 05） ; the rate of misdiagnosis decreased from 63.64% in 2008 to 14. 52% in 2014, showing an decreasing trend year by year, there was statistically signifi- cant difference （x2trend = 4. 130, P〈0. 05） ; the rate of laparotomy decreased from 45.45% in 2008 to 6. 45% in 2014, showing an decreasing trend year by year, there was statistically sign!ficant difference （x2trend=4. 134, P〈0. 05） ; the rate of uterine artery embolization （UAE） and curettage increased from 18. 18% in 2008 to 62. 90% in 2014, showing an increasing trend year by year, there was statistically significant difference （x2trend = 5. 288, P〈0. 05） . Conclusion From 2008 to 2014, the incidence rate of CSP increased, the percentage of early diag- nosis increased, the rate of misdiagnosis decreased, the rate of interventional therapy increased.
