OBJECTIVE: To identify the relation of missed abortions and intrauterine pathology. DESIGN: A postabortal hysteroscopy was performed 8 to 12 weeks after a dilatation and curettage (D&C) for missed abortion. SETTING: Department of Obstetrics and Gynecology, Assaf Harofeh Medical Center, Zerifin, Israel. PATIENTS: Sixty patients after a D&C for a missed abortion. MAIN OUTCOME MEASURES: The hysteroscopic appearance of the uterine cavity. RESULTS: Intrauterine adhesions occurred in only 10 patients (16.7%) with most of them of the mild type. A previous missed abortion was recorded in 60% of these cases. Uterine anomaly was found in one quarter of the cases, mainly an incomplete uterine septum. CONCLUSION: We believe that missed abortion does not predispose for intrauterine adhesions to the extent that was previously believed. A partial uterine septum is a major factor predisposing for the occurrence of missed abortion. Hysteroscopy after a missed abortion is an easy and efficient means for both identifying such uterine anomaly and excluding intrauterine adhesions.
Two cases of subclavian vein thrombosis following ovarian stimulation for in-vitro fertilization and subsequent ovarian hyperstimulation syndrome (OHSS) are described. Both occurred several weeks after complete resolution of the OHSS. The site of the lesions and their timing suggest that there is a generalized disturbance of coagulation associated with OHSS, which persists beyond the duration of the clinical syndrome.
The addition of color Doppler imaging (CDI) to the vaginal probe now enables sonographers to study more accurately the maternal-fetal circulation at the early stages of the gestation. Doppler studies of normal intrauterine first trimester gestations have been published, and our investigation was an attempt to study uteroplacental blood flow in abnormal intrauterine first trimester gestations. Although the calculated indices did not differ significantly from those found in normal gestations, we did find a higher rate of color detection in gestations defined as anembryonic as compared to those defined as missed abortions. Circulation abnormalities probably play a significant role in early pregnancy failures, and we believe CDI will help define the different etiologic mechanisms causing these early complications.
