ABSTRACT
Objective To investigate the clinical value of prenatal ultrasonography in diagnosing fetal aortic atresia.Methods Ultrasound images of 9 cases with fetal aortic atresia confirmed by autopsy were retrospectively analysed and summarized.Results Fetal echocardiography showed ascending aorta and aortic arch were thin in seven cases and unclear in two cases.Color Doppler flow imaging showed fetal aorta no blood connection with left ventricle and reverse blood flow in aortic arch among all 9 cases.There were 6 cases associated with hypoplastic left heart syndrome,two cases associated with ventricular septal defect and well-developed left ventricle,one case complicated with complete atrioventricular septal defect.Nine cases were detected at average gestational age (26.0 ± 2.6) weeks,minimum gestational age was only 16 weeks pregnant.Conclusions Prenatal ultrasound diagnosis of fetal aortic atresia has important clinical value.Ascending aorta and aortic arch are thin or unclear,no blood flow connection between fetal aorta and left ventricle and reverse blood flow in aortic arch are major diagnostic evidences.Color Doppler flow imaging is helpful for early diagnosis.
ABSTRACT
Objective To explore the influence of self-concealment level on patients'quality of life and clinical curative effect for curing refractory chronic prostatitis(RCP)by high-intensity focused ultrasound(HIFU). Methods Patients of RCP who meet the diagnostic criteria were assessed with the Self-Concealment Scale(SCS), TDL's table of self-assessing quality of life and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI).The patients whose SCS score were above the average score plus a standard deviation were taken as the high SCS group,and whose SCS Score were below the average score minus a standard deviation were taken as the low SCS group.The scores for CPSI and TDLs table of self-assessing quality of life and the clinical curative effect of the two groups were determined before and after the treatment by HIFU, respectively.Results The SCS score(35.75±10.34) of the RCP patients before HIFU treatment was significantly higher than the norm for male college students(29.20±8.73)(t=4.26,P<0.01).Two and six weeks after the HIFU application,the CPSI of both the high and the low SCS group decreased significantly(P<0.01),and the CPSI of the low SCS group de-creased more greatly than that of the high SCS group(P<0.01).The scores for TDL Life Quality Scale of low SCS group were significantly higher before and after two and six weeks'HIFU treatment than that of high self-concealment group(P<0.01).The TDL quality of life scale score of thelow SCS group increased respectively after two and six weeks'HIFU treatment (P<0.01),while for the high SCS group,this score increased only after six weeks' HIFU treatment(P<0.05).Six weeks after HIFU treatment,the clinical curative effect for the low SCS group was, observably better than that for high self-concealment(P<0.05).The SCS scores was significantly positive with CPSI scores(P<0.01),and significantly negative with the scores of TDL Life Quality Scale (P<0.01).Conclusion The symptom abatement,quality of life and clinical curative effect the RCP patients with a high self-concealment level were respectively worse after the HIFU treatment than that for whom with a low self-concealment level.
