子宫腔内病变的检查,在妇产科临床上极为重要,特别是不孕患者子宫因素的检查,历来就被重视.一般用输卵管造影(HSG)或宫腔镜法.可是,HSG对0.5cm以下的子宫内病变确诊是困难的,宫腔镜又需要特殊设备,前处置及技术繁杂,同时还有些问题.为此作者应用HSG并用CO_2注入宫腔的双重造影法.现将所观察到的子宫内膜微细变化报导如下.不孕门诊患者162名作为子宫双重造影的对象,在透视下,慢慢向宫腔内注入水溶性造影剂,使充满宫腔,观察宫腔形态后,再追加造影剂直至造影剂由输卵管伞端漏到盆腔或患者自述腹痛为止.观察输卵管的疏通性后,使造影剂尽可能由于宫颈管流出.继之,通过通气用装置向宫腔内以30ml/min速度注入CO_2,则可得到子宫腔双重造影像.HSG法或双重造影法发现宫腔内有异常时,要作
Uterine lesions of the examination, is extremely important in the clinical obstetrics and gynecology, especially in infertility patients uterine factors, has always been valued .Use fallopian tube angiography (HSG) or hysteroscopy.However, HSG 0.5cm The following intrauterine lesions is difficult to diagnose, hysteroscopy and special equipment, pre-treatment and technical complexity, while there are some problems.To this end, the authors apply HSG and CO_2 into the uterine cavity by dual contrast imaging method is now observed Micro changes in endometrial reported as follows.Intravenous outpatient 162 patients as the uterus double contrast of the object, under fluoroscopy, slowly into the uterine cavity into the water-soluble contrast agent, so full of uterine cavity, observe the uterine cavity morphology, then append Contrast agent until the contrast agent leaked from the tubal umbrella side to the pelvic or abdominal palpitations since the patient observed the dredging tubal, the contrast agent as much as possible out of the cervical canal outflow.Then, through the ventilation device to the uterine cavity at 30ml / min Speed injection of CO_2, you can get double uterine cavity imaging .HSG method or double contrast abnormalities found in the uterine cavity, to be made
