目的探讨阴道斜隔综合征(OVSS)经腹联合腔内三维超声的特征,提高超声对OVSS的诊断准确率。方法回顾性分析42例手术证实OVSS患者的临床资料,并与手术结果对照分析。结果 42例OVSS患者中,左侧斜隔18例,右侧斜隔24例;Ⅰ型(无孔斜隔)12例、Ⅱ型(有孔斜隔)23例和Ⅲ型(无孔斜隔合并宫颈瘘管)7例。超声显示,42例患者均合并子宫畸形和斜隔侧肾脏缺如,其中双子宫37例,纵隔子宫4例,双角子宫1例;隔后腔积液39例,斜隔侧宫腔和宫颈管积液11例,斜隔侧输卵管积液7例,斜隔侧卵巢子宫内膜异位囊肿3例。经腹联合腔内三维超声诊断与手术结果符合率为100%(28/28),高于二维超声83.3%(35/42)。结论子宫畸形伴隔后腔积液及斜隔侧肾缺如为OVSS的声像图特征,经腹联合腔内三维超声对OVSS的诊断具有重要的临床价值。
Objective To investigate the characteristics of transvaginal intracavitary three dimensional ultrasound in patients with vaginal oblique syndrome (OVSS) and to improve the diagnostic accuracy of ultrasound in the diagnosis of OVSS. Methods The clinical data of 42 patients with surgically proven OVSS were retrospectively analyzed and compared with the surgical results. Results In 42 patients with OVSS, there were 18 cases of left oblique septum and 24 cases of right oblique septum. There were 12 cases of type I (non-perforated oblique), 23 cases of type II (oblique septum) and type III Combined cervical fistula) 7 cases. Ultrasound showed that 42 patients were complicated with uterine malformations and lack of oblique renal side of the oblique side, including 37 cases of double uterus, 4 cases of mediastinal uterus, 1 case of double angle uterus; 39 cases of septal fluid, the oblique side of the uterine cavity and cervix 11 cases of tubular effusion, oblique septal tubal effusion in 7 cases, 3 cases of oblique ovarian endometriosis cyst. The coincidence rate of transabdominal intra-three-dimensional sonography and surgery was 100% (28/28), higher than that of two-dimensional ultrasound 83.3% (35/42). Conclusions Uterine anomalies with posterior septal effusion and oblique septal renal insufficiency are the features of OVSS. The diagnosis of OVSS by transabdominal combined intra-three-dimensional ultrasound is of great clinical value.
