【摘要】：目的对比超微血管成像技术和经腹彩色多普勒超声两种血流模式对人流后宫腔内异常回声团块血流的显示情况,探讨超微血管成像技术对判断人流后结局的应用价值。方法对80例人流后持续出血的患者的子宫分别行经腹彩色多普勒血流显像和超微血管成像检查。对宫腔内检测出异常回声团块内的血流丰富程度进行分级;并以团块内检测出RI值为0.4~0.5的滋养细胞血流信号作为组织物残留的诊断标准,并与清宫术后病理结果相对照。结果 80例患者中,清宫术后病理结果为变性、坏死或机化的蜕膜、绒毛组织的65例,为血凝块的15例。用彩色多普勒检查宫内异常回声团块血流分布3~4级的患者45例,占56.2%,能检测出滋养细胞血流信号的患者50例,占76.9%;用超微血管成像检查宫内异常回声团块血流分布3~4级的患者60例,占75.0%,能检测出滋养细胞血流信号的患者65例,占100%。两种方法检验结果相比,P0.05,差异有统计学意义。结论超微血管成像显示人流后宫腔内异常回声团块内血流信号的能力优于经腹彩色多普勒成像,能显示更微小的血管,对人流后结局的判断更准确。
[Abstract]:Objective to compare the display of abnormal echo mass blood flow in uterine cavity with two blood flow patterns: ultramicrovascular imaging and transabdominal color Doppler ultrasound, and to explore the value of hypermicrovessel imaging in judging the outcome of artificial abortion. Methods Transabdominal color Doppler flow imaging and supermicrovessel imaging were performed in 80 patients with continuous bleeding after abortion. The rich degree of blood flow in the abnormal echo mass was classified. The blood flow signal of trophoblastic cells with RI of 0.4 ~ 0. 5 was detected as the diagnostic criterion of tissue residue, and the results were compared with the pathological results after operation. Results the pathological results of 80 cases were degeneration, necrosis or organization of decidua, 65 cases of chorionic villi and 15 cases of hemagglutination. There were 45 cases (56.2%) with abnormal echo mass blood flow distribution in the uterus, 50 cases (76.9%) were able to detect the blood flow signal of trophoblast. There were 60 cases (75.0%) with abnormal echo mass blood flow distribution in the uterus, 65 cases (100%) were able to detect the blood flow signal of trophoblast. Compared with the results of the two methods, P0.05, the difference was statistically significant. Conclusion Super-microvessel imaging is superior to transabdominal color Doppler imaging in displaying blood flow signal in abnormal echo mass of uterine cavity after artificial abortion. It can display smaller blood vessels and is more accurate in judging the outcome after abortion.
