Clinical analysis of uterine arterial embolization combined with hysteroscopy in the treatment of cesarean scar pregnancy / 中国基层医药

ABSTRACT

Objective To investigate the clinical efficacy of uterine arterial embolization combined with hysteroscopy in the treatment of cesarean scar pregnancy.Methods From September 2016 to March 2018, 68 patients with cesarean scar pregnancy in the People's Hospital of He'nan Province were collected .According to different treatment methods ,the patients were divided into observation group and control group .The observation group (42 cases) firstly received bilateral uterine artery embolization ,then hysteroscopy pregnancy lesion was resected after 2 -3 days.The control group (26 cases) directly received hysteroscopy endoscopic pregnancy lesion resection . Results There were 42 cases in the observation group,2 cases(all of them III type)failed,of which 1 case was treated with laparoscopy ,and 1 case was converted to transvaginal focus clearance .In the control group ,26 cases of cesarean scar pregnancy were treated directly by hysteroscopy ,and 6 cases were failed(1 case of type I,4 cases of type II,1 case of type III),among which 3 cases were treated with uterine artery embolization .Then hysteroscopic surgery was performed in 2 cases,combined with laparoscopy for pregnancy focus debridement .One case of severe hemorrhage occurred in III type operation ,which was immediately converted to open operation .The operation time,intraoperative blood loss ,surgical success rate , length of hospital stay , blood β-HCG return to normal time , menstrual recovery time,postoperative vaginal bleeding , postoperative vaginal bleeding time in the observation group were ( 17.09 ± 3.62)min,(32.6 ±5.6)mL,95.2％(40/42),(4.76 ±1.63)d,(18.00 ±6.62)d,(30.28 ±4.23)d,(32.75 ± 8.32)mL,(3.26 ±1.06)d,respectively,which in the control group were (49.51 ±3.41)min,(60.3 ±13.6)mL, 76.9％(20/26),(7.23 ±1.96)d,(22.00 ±6.91)d,(36.41 ±7.62)d,(46.23 ±11.73)mL,(6.42 ±2.45)d, respectively,the differences between the two groups were statistically significant (t=36.68,14.09,χ2 =5.189,t=5.62,2.30,4.27,5.54,7.35,all P <0.05).Conclusion Bilateral uterine artery embolization combined with hysteroscopy in the treatment of cesarean scar pregnancy has some advantages including high successful rate , short operation time,less bleeding,hospitalization time and postoperative recovery ,etc.It is a safe and effective treatment especially for type I and type II scar pregnancy .
