Clinical analysis of three-dimensional computerized tomography angiography super selective uterine artery embolization in treating placenta increta

Abstract

Objective To evaluate the clinical efficacy of three-dimensional computerized tomography angiography(CTA) super selective supplying artery embolization in treating placenta increta; The supplying artery is for placenta increta. Methods The clinical data of 70 placenta increta patients were collected in Huadu Hospital Affiliated to Southern Medical University from February 2010 to December 2013. The patients were divided into two groups: 35 patients with three-dimensional CTA super selective artery embolization were in the treatment group, 35 patients with uterine artery embolization were in the control group. The clinical condition about patients during preoperative, intraoperative, and postoperative and prognosis of two groups were compared. Results In the treatment group, the time of placental tissue discharge were (7.05±1.28) days, the level of β-human chorionic gonadotropin(β-hCG) was (5.35±0.67) U/L, and the amount of postoperative bleeding was (9.78±0.34)ml. In the control group, the data were (12.36±1.95) days, (6.97±0.99)U/L, and (15.22±1.96)ml, respectively. There were significant differences in the two groups; t=4.102, 4.009, and 4.135 (all P value<0.01). There was none patient had uterus cavity infection in control group, but there were 3 patients had uterus cavity infection in treatment group. Conclusions The advantages of three-dimensional CTA super selective uterine artery embolization are safe, mini-invasive, stopping bleeding quickly, and reserving uterine for placenta increta patients. The therapeutic method has high clinical application value. Key words: Placenta accreta; Embolization, therapeutic; Three-dimensional CTA; Outcome assessment
