ABSTRACT
Objective To evaluate the clinical value of ultrasonography in the diagnosis of hermaphroditism.Methods Ultrasonographic appearances of 45 cases with hermaphroditism were reviewed retrospectively,and the results were compared with clinical data.Results All cases were confirmed pathologically.5 cases showed true hermaphroditism (11.1％),14 cases showed male pseudohermaphroditism (31.1 ％),24 cases showed female pseudohermaphroditism (53.3 ％),2 cases showed gonadal dysgenesis(4.4％).Compared with pathological results in the ultrasound examination,4 cases showed true hermaphroditism,the coincidence rate was 80％.11 cases showed male pseudohermaphroditism,the coincidence rate was 78.6％.20 cases showed female pseudohermaphroditism,the coincidence rate was 83.3％.1 cases showed gonadal dysgenesis,the coincidence rate was 50.0％.Conclusions Ultrasonography can not only evaluate internal reproductive organs in the patients,but also estimate the site,size,morphology and structure,which provides important imaging evidence for the clinical diagnosis and treatment.
ABSTRACT
Objective To explore the clinical value of Doppler tissue imaging (DTI) in evaluating abdominal aortic wall motion to predict pregnancy-induced hypertension (PIH).Methods The velocities of anterior abdominal aortic wall motion in 112 pregnant women with normal 20-40 weeks' pregnancy were detected by DTI and combined with simultaneous electrocardiography.Electromechanical time (EMT), left ventricular pre-ejection period (PEP), patients' height and weight were measured and recorded respectively.Pulsed wave time (PWT, PWT = EMT-PEP) and relative pulse wave velocity (RPWV) were calculated and analyzed.Medium and late stage PIH eases and time were recorded in clinical follow-up.Results PIH group were 11 cases, non-PIH group were 101 cases.E, S_1, S_2, D peak value in PIH group were significantly lower than those in non-PIH group [(2.02 ± 0.39 ) cm/s vs (2.32 ± 0.45 ) cm/s, (6.08 ± 0.87 ) cm/s vs(7.12 ±1.11 ) cm/s, (2.22 ± 0.65 ) cm/s vs( 2.83 ± 0.81 ) cm/s, (3.26 ± 0.54) cm/s vs( 3.86 ± 0.72 ) cm/s, P < 0.01]; EMT shortening[(120.87 ± 11.34) ms vs (134.32 ± 10.62) ms,P<0.05];PEP longer[(92.36±9.04) ms vs(83.11±8.95) ms,P< 0.05];PWT shortening[(31 ± 11) ms vs(45 ± 13) ms,P<0.01]; RPWV faster [( 1 02.28 ± 20.69) m/s vs (75.37 ± 18.74) m/s, P < 0.01].Conclusions Abdominal aortic wall motion has already changed in early stage of PIH.DTI is a valuable method to evaluate the abdominal aorta wall motion for early detection of PIH with high sensitivity, high accuracy and access to promote.
