RESUMEN
Objective To analyze the diagnostic value of transvaginal three-dimensional ultrasound in intrauterine adhesion.Methods The data in 75 patients with intrauterine adhesion confirmed by hysteroscopy surgery and conducting transvaginal twodimensional and three-dimensional ultrasound examination in this hospital from November 2014 to November 2016 were retrospectively analyzed.Results The diagnostic accuracy rate of the three-dimensional transvaginal ultrasound for diagnosing intrauterine adhesion reached 87.7 ％,which of two-dimensional ultrasound reached 69.2 ％;the accuracy rates of transvaginal two-dimensional ultrasound for detecting mild,middle and severe intrauterine adhesion were 56.7％,76.9％ and 88.9％ respectively,while which of transvaginal three-dimensional ultrasound were 76.7 ％,96.2 ％ and 100.0 ％ respectively;the accuracy rates of transvaginal two-dimensional ultrasound for detecting peripheral,central and mixed intrauterine adhesion were 66.7％,76.7％ and 54.5％ respectively,while which of transvaginal three-dimensional ultrasound were 83.3％,88.7％ and 100.0％ respectively;the accuracy rate of three-dimensional transvaginal ultrasound was significantly superior to that of transvaginal two-dimensional ultrasound,the difference was statistically significant (P＜0.05).Conclusion Compared with transvaginal two-dimensional ultrasound,transvaginal three-dimensional ultrasound is more accuracy in diagnosing intrauterine adhesion and can provide more information for clinical doctors.
RESUMEN
Objective To evaluate the value of transvaginal two-dimensional and three-dimensional ultrasound in diagnosis of cesarean scar pregnancy (incision area pregnancy ) after cesarean section .Methods Thirty cases of cesarean incision pregnancy at lower section of uterine anterior wall diagnosed by transvaginal two-dimensional ultrasound during 2015-2016 were retrospectively analyzed .On this basis ,all cases conducted transvaginal three-dimensional ultrasound and were verified by magnetic resonance(MR) examination .Then the values of transvaginal two-dimensional and three-dimensional ultrasound in diagnosis of incision area preg-nancy were analyzed .Results One case was diagnosed as the incision site and partial implantation of pregnant capsule by transvagi-nal two-dimensional ultrasound ,and then diagnosed as the complete implantation of pregnant capsule at incision site ,the other types were consistent to the diagnosis by the three-dimensional ultrasound .The MR examination results were consistent to the those by three-dimensional ultrasound .The diagnosis typing coincidence rate had no statistical difference among the three methods ( P>0 .05) .Conclusion Transvaginal three-dimensional can more intuitively display the lesion′s position ,range ,incision involvement sit-uation ,while transvaginal two-dimensional ultrasound has more plentiful diagnostic information .
RESUMEN
Objective To explore the diagnostic value of transvaginal three-dimensional ultrasound in uterus abnormal bleeding caused by uterine incision diverticulum after cesarean section. Methods We collected 480 cases with cesarean section patients from January 2011 to July 2015 in our hospital. A retrospective analysis of the cases was performed by transvaginal ultrasound , if the incision diverticulum was found , for measuring and recording the depth , length , width and assessing the residual muscle layer thickness and the shape and volume of the diverticulum with vaginal bleeding in the following up. Results 118 cases were found incision diverticu-lum by ultrasound in 480 patients , including 70 cases of triangular , 33 cases of semicircle , 15 cases of other shapes , of which 56 patients of uterine abnormal bleeding were significantly correlated with the volume and depth of the diverticulum. While menstruation PBAC scores were higher , the greater probability associated with abnormal uterine bleeding , but bleeding did not associate with the shape and length and width of diverticula; In this study we also found that OR value (OR = 15.809) of the diverticulum volume maximum was the key factors leading to the abnormal uterine bleeding in uterine incision diverticulum. Conclusion Transvaginal three-dimen-sional ultrasound can be convenient , fast and accurate diagnosis of uterine abnormal bleeding caused by incision diverticulum , and is of important significance for guiding clinical medication and surgical treatment.
