经直肠彩色多普勒超声诊断青春期多囊卵巢综合征

目的探讨经直肠超声对青春期多囊卵巢综合征(PCOS)的诊断价值。方法对我院2007年10月～2009年10月32例青春期PCOS患者经直肠超声检查,并运用彩色多普勒观察双侧卵巢血流情况和卵巢二维超声表现。结果PCOS患者双侧卵巢体积均匀增大,大于10ml,双侧卵巢呈多囊样改变,见12个以上小囊,小囊直径多小于10mm。卵巢间质回声增强,血流较丰富,血管分布面积增宽。卵巢间质动脉血流阻力指数降低,小于0.6。结论经直肠超声对青春期PCOS的诊断有较好的临床应用价值,较腹部超声有明显优势。

Objective To explore the diagnostic value of color dopplar ultrasound by transrectal used in adolescent polycystic ovary syndrome （PCOS）. Methods 32 cases of adolescence PCOS patients from 2007 October to 2009 October were diagnosed by ultrasound examination, the bilateral ovarian two-dimensional ultrasound syndrome and blood flow condition were observed by transrectal color dopplar. Results Bilateral ovarian volume of PCOS patients increased evenly, more than 10ml, and showed on much bursa model changes. More than 12 folliculi can be seen, and the diameter of much was less than 10mm.Ovarian mesenchyme echo enhanced, blood vessels were rich, and width of distribution area increased. Resistance index of ovarian stromal artery flow reduced to less than 0.6. Conclusion The transrectal ultrasound showed a good value of clinical applications in diagnosis of adolescent PCOS, which has obvious advantages than abdominal ultrasound.
