【摘要】：目的应用经阴三维超声评价分析妊娠晚期女性盆膈裂孔的形态结构。方法选择2012年1月至2014年12月来该院产检的60例孕周为31~40周的孕妇作为观察组,将同期因月经不调就诊的60例未育女性作为对照组,全部患者均进行经阴三维超声检查,观察盆膈裂孔在各个时期的形态结构,并测量比较两组患者盆膈裂孔的左右径、前后径及面积。结果 (1)正常盆膈裂孔形态呈"菱形"列裂隙样结构,观察组患者中43.33%盆膈裂孔形态出现异常,呈"类椭圆形";(2)在静息期、缩肛期及张力期3种状态下,观察组患者盆膈裂孔的左右径、前后径及面积均明显比对照组大,两组比较差异有统计学意义(P0.05);与静息期比较,全部研究对象的盆膈裂孔的左右径、前后径及面积在缩肛期均减小,在张力期均增大,差异有统计学意义(P0.05)。结论经阴三维超声能清晰观察到女性盆膈裂孔的形态结构,且可对其进行有效评价,与未育女性比较,妊娠晚期女性盆膈裂孔显著增大,出现松弛现象,且部分出现形态异常。
[Abstract]:Objective to evaluate and analyze the morphology of pelvic and phrenic hiatus in late pregnancy women by transvaginal three-dimensional ultrasound. Methods from January 2012 to December 2014, 60 pregnant women with gestational age of 31 to 40 weeks were selected as the observation group, and 60 unfertile women who were not pregnant at the same time because of irregular menstruation were selected as the control group. All the patients were examined by transvaginal three dimensional ultrasound. To observe the shape and structure of the pelvic diaphragm hole in each period, and to measure and compare the left and right diameters, anteroposterior diameter and area of the pelvic diaphragm hole between the two groups. Results (1) the shape of the normal pelvic phrenic fissure was "rhomboid", and 43.33% of the patients in the observation group had abnormal shape, which was "oval like". (2) in the resting period, anus contraction period and tension period, the left and right diameter, anteroposterior diameter and area of the pelvic diaphragm hiatus in the observation group were significantly larger than those in the control group, and the difference between the two groups was statistically significant (P0.05). Compared with the rest period, the left and right diameter, anterior and posterior diameter and area of the pelvic diaphragm hiatus of all the subjects decreased in the anus contraction period, and increased in the tension period, the difference was statistically significant (P0.05). Conclusion the shape and structure of female pelvic diaphragm hiatus can be clearly observed by transvaginal three-dimensional ultrasound, and it can be effectively evaluated. Compared with unbred women, the pelvic diaphragm hiatus in women in the third trimester of pregnancy is obviously enlarged, the phenomenon of relaxation appears, and some of them are abnormal in shape.
