【摘要】：目的對比超微血管成像技術和經(jīng)腹彩色多普勒超聲兩種血流模式對人流后宮腔內異常回聲團塊血流的顯示情況,探討超微血管成像技術對判斷人流后結局的應用價值。方法對80例人流后持續(xù)出血的患者的子宮分別行經(jīng)腹彩色多普勒血流顯像和超微血管成像檢查。對宮腔內檢測出異�；芈晥F塊內的血流豐富程度進行分級;并以團塊內檢測出RI值為0.4~0.5的滋養(yǎng)細胞血流信號作為組織物殘留的診斷標準,并與清宮術后病理結果相對照。結果 80例患者中,清宮術后病理結果為變性、壞死或機化的蛻膜、絨毛組織的65例,為血凝塊的15例。用彩色多普勒檢查宮內異�；芈晥F塊血流分布3~4級的患者45例,占56.2%,能檢測出滋養(yǎng)細胞血流信號的患者50例,占76.9%;用超微血管成像檢查宮內異常回聲團塊血流分布3~4級的患者60例,占75.0%,能檢測出滋養(yǎng)細胞血流信號的患者65例,占100%。兩種方法檢驗結果相比,P0.05,差異有統(tǒng)計學意義。結論超微血管成像顯示人流后宮腔內異常回聲團塊內血流信號的能力優(yōu)于經(jīng)腹彩色多普勒成像,能顯示更微小的血管,對人流后結局的判斷更準確。
[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.
