The author studied 104 renal arteries of healthy people and 106 renal arteries of hypertension patients by color Duplex ultrasound and DSA, and then compared these findings. Results: color Duplex ultrasound can detect 96% of renal arteries. Ultrasound can be used to study renal arteries with 3 positions gave high rate of detection: anterior abdominal position 96%, right subcostal position 94%, and translumbar position 98%

With the results obtained from study realized on 90 "normal" elderly subjects and 686 elderly patients with hypertension and/or diabetes showed that: There is no difference on intima-media thickness (IMT) of carotid artery and its bifurcation between right site and left site. The average IMT at common carotid artery and its bifurcation between is sinificantly higher in elderly patients with hypertension and/or diabetes than in "normal" elderly subjects. The rate of thickness of carotid IMT and its birfucation in the elderly with hypertension and/or diabetes is significantly higher than "normal" elderly subjects. This rate has no difference between age-groups but significantly higher in men.

40 hypertension patients aged from 45-75 years, with the signs of thickening of left heart ventricle detected by radiography, ECG and ultrasound were enrolled in tis study. The control group includes 35 other patients with the same range of age and the same stage of hypertension without thickening of left heart ventricle. The authors didn’t find any relation between the thickening of left heart ventricle and arrhythmia.

BACKGROUND: For diagnosis of hypertension, prompt blood pressure measurement is necessary. In a clinical setting, increased blood pressure is often recorded during urine-holding. The aim of this study was to assess the effect of urine-holding on blood pressure. METHODS: We analyzed 172 subjets who visited a hospital in Pusan for examinafion of pelvic ultrasonography. We measured urine holding time, blood pressure in a urine-holding state, and blood pressure immediately after urination when pelvic ultrasonography was examined. Paired t-test was performed to compare the pre-voiding blood pressure. The relationship between urineholding time and difference in blood pressure were assessed by Pearsons's correlatian coefficients. RESULTS: In subjects who held urine for no less than 3 hours, mean pre-voiding systolic blood pressure was 124.2+/-20.8 mmHg, mean pre-voiding diastolic blood pressure was 78.3+/-13.3 mmHg, post-voiding systolic blood pressure was 120.0+/-21.0 mmHg, and post-voiding diastolic blood pressure was 75.4+/-12.3 mmHg. Mean difference in systolic bload pressure was 4.2+/-10.7mmHg, and mean difference in diastolic blood pressure was 2.8+/-7.7 mmHg(p<0.05). The correlation between urineholding time and differences in systolic and diastolic blood pressure was not significant(P>0.05) CONCLUSION: Urine-holding for no less than 3 hours made systolic and diastolic blood pressure rise. However, the rise in blood pressure was not proportianal to urine-holding time.

The effects of angiotensin II receptor antagonist losartan on elastic properties of aorta in patients with mild to moderate essential hypertension were assessed. The ascending aortic distensibility in 26 patients (48 +/- 3 years) with mild to moderate essential hypertension before and after 12 weeks of treatment with losartan (50 mg/day) was evaluated by using two-dimensional echocardiography. M-mode measurements of aortic systolic (Ds) and diastolic diameter (Dd) were taken at a level approximately 3 cm above the aortic valve. Simultaneously, cuff brachial artery systolic (SBP) and diastolic (DBP) pressures were measured. Aortic pressure-strain elastic modulus (Ep) was calculated as Dd x (SBP-DBP)/(Ds-Dd) x 1333 and stiffness index beta (beta) was defined as Dd x Ln (SBP/DBP)/(Ds-Dd). Blood pressure significantly decreased from 148 +/- 13/95 +/- 9 mmHg to 138 +/- 12/88 +/- 8 mmHg (systolic blood pressure, P = 0.001; diastolic blood pressure, P = 0.003). There was no significant difference in pulse pressure before and after treatment with losartan (53 +/- 10 mmHg vs 50 +/- 7 mmHg). The distensibility of ascending aorta increased significantly as showed by the significant decrease in pressure-strain elastic modulus from 4.42 +/- 5.79 x 10(6) dynes/cm2 to 1.99 +/- 1.49 x 10(6) dynes/cm2 (P = 0.02) and stiffness index beta from 27.4 +/- 32.9 to 13.3 +/- 9.9 (P = 0.02). Although there was a weak correlation between the percent changes in pressure-strain elastic modulus and stiffness index beta and that in diastolic blood pressure after losartan treatment (r = 0.40, P = 0.04 and r = 0.55, P = 0.004, respectively), no correlation was found between the percent changes in pressure-strain elastic modulus and stiffness index beta and that in systolic blood pressure (r = 0.04, P = 0.8 and r = 0.24, P = 0.2, respectively). Our study demonstrated that angiotensin II receptor antagonist losartan has a beneficial effect on aortic distensibility in patients with mild to moderate essential hypertension and this effect is partly independent of blood pressure reduction.

Endoscopic drainage of pancreatic pseudocysts is the initial treatment of choice for symptomatic pancreatic pseudocysts and nonresolving pseudocysts. Recently, endoscopic ultrasound (EUS) has been used as a guide for transmural entry and the safer drainage of pancreatic pseudocysts. We report a case of therapeutic linear array EUS-guided pseudocyst drainage without the use of fluoroscopy in a patient with portal hypertension.

Esophagogastric varices are considered to be the most common complication in patients with portal hypertension. Among ectopic varices, rectal varices are infrequent but potentially serious complication. The etiology and pathogenesis of rectal varices remains controversial. Several kinds of treatment have been performed but standard treatment for rectal varices has not been established. Herein we report a case of rectal varix bleeding treated with endoscopic variceal ligation (EVL) and then evaluated by transrectal color doppler ultrasonography.

Chronic liver disease is a major disorder worldwide. A better understanding of anatomy, blood flow, and pathophysiology may be a key issue for their proper management. Ultrasound (US) is a simple and non-invasive diagnostic tool in the abdominal field. Doppler mode offers real-time hemodynamic evaluation, and the contrast-enhanced US is one of the most frequently used modalities for the detailed assessment. Further development in digital technology enables three-dimensional (3D) visualization of target images with high resolution. This article reviews the wide ranges of application in the abdominal US and describes the recent progress in the diagnosis of chronic liver diseases.

BACKGROUND: Doppler velocimetry studies of placental and fetal circulation can provide important information regarding fetal well­being providing an opportunity to improve fetal outcome. The present study was undertaken to evaluate the role of middle cerebral to umbilical artery pulsatility index ratio (MCA/UA PI Ratio) as a predictor of perinatal outcome in hypertensive pregnant patients admitted from January 2009- December 2011 at the De La Salle-University Medical Center
OBJECTIVES: To correlate the neonatal outcomes of hypertensive pregnant women at 28-34 weeks AOG with the middle cerebral artery and umbilical artery pulsalitility index ratio.
STUDY DESIGN: A retrospective cohort was done on records of patients with hypertension who delivered from January 2009 - Decem­ber 2011. Doppler ultrasound results of said patients that were available at the OB-GYN ultrasound section were recorded and the MCA/UA PI Ratio computed. Doppler results were then compared to neonatal outcomes
RESULTS: Results of the study shows that 10 out of the 17 hypertensive patients with decreased MCA/UA PI Ratio developed Intrau­terine growth restriction. 62.5% of those patients who had normal MCA/UA PI Ratio results delivered term, while 87.5% of those who had decreased MCA/UA PI Ratio delivered preterm (P <0.002). However results of the MCA/UA PI ratio has no association on APGAR scores at 1 and 3 minutes.
CONCLUSION: Decreased MCA/UA PI Ratio results have an association on the development of adverse neonatal outcomes in hyper­tensive pregnant women.
