Prediction of smallness for gestational age by maternal serum human chorionic gonadotropin levels and by uterine artery Doppler study.

OBJECTIVES: To compare the utility of maternal serum human chorionic gonadotropin (MShCG) levels with that of uterine artery Doppler study in predicting small for gestational age (SGA) birth and pregnancy-induced hypertension (PIH). METHODS: MShCG assay and uterine artery Doppler study were performed in 359 consecutive pregnant women with singleton pregnancies. MShCG levels > or =2.0 multiples of the median at 15-18 weeks' gestation were considered to be elevated. An abnormal uterine artery Doppler velocimetry at 21-24 weeks' gestation was defined as a mean pulsatility index above the 95th percentile or the presence of an early diastolic notch in either uterine artery. The predictive values of MShCG levels and uterine artery Doppler velocimetry were evaluated for the risk of SGA birth and PIH. RESULTS: Forty-one subjects gave birth to SGA infants, and 20 developed PIH. Patients with MShCG elevation or abnormal uterine artery Doppler velocimetry showed a significantly higher incidence of SGA infants than the controls. The sensitivity and specificity of MShCG elevation for SGA birth were 17.1 and 93.4%, respectively, compared with abnormal uterine artery Doppler velocimetry, which had 24.4 and 94.3%, respectively. There was no significant difference between these methods. Elevated levels of MShCG and abnormal uterine artery Doppler velocimetry were not associated with PIH. CONCLUSION: Elevated levels of second-trimester MShCG were as sensitive and specific in predicting SGA births as abnormal uterine artery Doppler velocimetry.

Hysteroscopic selective salpingography.

OBJECTIVE: To evaluate the effectiveness of hysteroscopic selective salpingography (HSS) as a method for diagnosing the tubal proximal occlusion shown by hysterosalpingography (HSG). DESIGN: Prospective study. SETTING: Outpatient Department of Obstetrics and Gynecology, Social Insurance Saitama Chuo Hospital, Urawa, Japan. PATIENT(S): A total of 572 infertile women underwent HSG. Forty-seven of 50 women with unilateral or bilateral proximal tubal occlusion demonstrated by HSG underwent HSS. INTERVENTION(S): Hysteroscopic selective salpingography was performed for the diagnosis of tubal occlusion in cases in which the proximal tubal occlusion was shown by HSG. MAIN OUTCOME MEASURE(S): Number of patients who underwent HSS and pregnancy rate after HSS. RESULT(S): Twenty-seven (79.4%) of 34 patients with unilateral occlusion diagnosed by HSG were shown to have normal patency by HSS. Of 12 women with bilaterally normal patent tubes confirmed by HSS, 8 (66.7%) achieved normal pregnancies within 1 year. Seven (53.8%) of 13 patients with bilateral occlusion found by HSG were shown to have normally patent tubes by HSS. CONCLUSION: The simple method of HSS was clinically effective for evaluating the presence of proximal tubal occlusion.

Evaluation of the radiologic findings on hysterosalpingography by selective hydrotubation with flexible hysterofiberscope.

PURPOSE: The objective of this study was to assess further the significance and accuracy of hysterosalpingography (HSG) by comparing the radiologic findings on HSG to selective hydrotubation (SHT) using a hysterofiberscope in 106 women with tubal occlusion. RESULTS: Patency was successfully observed by SHT in 72 of 134 tubes and 62 of 106 patients. Proximal obstruction was divided into three groups according to the shape of cornual obstruction (sharp, dull, defect) on HSG. The success rate for SHT in unilateral obstruction (64%) were significantly higher than those in bilateral obstruction (39%). In the three groups of proximal obstruction, the success rates for SHT were 24, 75, and 30% in sharp, dull, and defect, respectively. The group of dull had significantly higher success rate than the groups of sharp and defect. Thirteen of 62 patients who successfully recanalized became pregnant at 9-month follow-up interval. CONCLUSION: Careful evaluation of the cornual obstruction in radiologic findings on HSG may be important for the decision on further treatment. Furthermore, SHT using a hysterofiberscope is an effective method for evaluating tubal obstruction and for managing it in a selected group of patients with tubal obstruction.
