11. Doppler Velocimetry in the Evaluation of Fetal Well-Being
Sammanfattning : Ultrasound Doppler velocimetry was used to predict fetal well-being. The uterine artery blood velocimetry seemed to be a good predictor of perinatal outcome in high-risk pregnancies and a complement to umbilical artery velocimetry. The fetal middle cerebral artery blood velocimetry might be an early sign of fetal hypoxia. LÄS MER
12. Ultrasound in the management of women with post-menopausal bleeding
Sammanfattning : The aim of this thesis was to investigate how ultrasound can be used in the diagnostic work-up of women with post-menopausal bleeding (PMB) to optimise and individualise their management. The thesis is based on six studies comprising post-menopausal women with (Study I-VI) and without (Study VI) abnormal bleeding. LÄS MER
13. Perinatal mortality among immigrants from Africa´s Horn: The importance of experience, rationality, and tradition for risk assessment in pregnancy and childbirth
Sammanfattning : This thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. LÄS MER
14. Thermal endometrial destruction by means of a balloon catheter : experimental and clinical evaluation of a new form of treatment for menorrhagia
Sammanfattning : Thermal endometrial destruction by means of a silicone balloon catheter is a new form of treatment for menorrhagia aimed at reducing menstrual blood loss. The purpose of the present work was to study, experimentally, the thermal effects on and the thermal conductivity of uterine tissue, to obtain a basis for the estimation of optimal treatment conditions by means of numerical analyses using a computer simulation model, to elucidate possible problems which may arise during the procedure, to evaluate how the patients tolerated this treatment and to judge which patients were suitable for this form of treatment and, finally, to study the uterine cavity after treatment and the long-term results of treatment.

15. Brain-sparing Circulation in Growth-restricted Human Fetuses
Sammanfattning : The aim of the studies was to explore fetal circulatory changes relative to development of brain-sparing flow (BSF) in growth-restricted fetuses exposed to acute hypoxic stress, as provoked by uterine contractions during an oxytocin challenge test (OCT).(1) In fetuses with a normal cerebral circulation during basal conditions, signs of an acute hyperperfusion in both the arterial and venous cerebral vascular systems were demonstrated in response to acute hypoxic stress; (2) Fetuses with an already established BSF showed no further ability of brain-sparing during acute hypoxic stress; (3) In venous cerebral vessels of fetuses with established BSF, the flow responses to hypoxic stress were equivocal, indicating different reactions in areas drained by different veins, or a deranged physiological vascular response; (4) Blood flow changes occurred synchronized in the middle and anterior cerebral arteries when fetuses with an intact cerebral circulation were exposed to hypoxic stress; (5) When fetuses with an established BSF showed no further changes in the middle cerebral artery, no changes were found in the anterior cerebral artery either.
