Medical Imaging Role in Renovascular Hypertension Diagnosis

Renal artery stenosis is an important clinical entity. its importance lies in that it may be a treatable cause of hypertension, and it is -when progress- a cause of chronic renal failure. The causes of renal artery stenosis are numerous, the most common are: atherosclerosis and fibromuscular dysplasia (accounts for more than 95% of cases). Digital Subtraction Angiography (DSA) is the standard reference in the radiologic diagnosis of renal artery stenosis, but it carries the risk of being invasive procedure. Doppler ultrasound is used in the evaluation of the renal arteries, and it has the advantage of being non-invasive and inexpensive.

Prediction of intrauterine growth retardation and pregnancy induced hypertension by uterine artery doppler

To find out the correlation between persistence of uterine artery notch and development of intrauterine growth retardation (IUGR) and pregnancy induced hypertension (PIH), and to see if Doppler assessment can help identify high risk pregnancies.

Doppler Echo Cardiographic Determinnaton Of The Puulmonary Hypertension And Right Ventricular Pressure In Patnts With Ventricular Septal Defects

The study was performed in 64 children aged 6 months to 5 years had ventricuLar septal defect. Systolic pressure in the right ventricle and Pulmonary Hypertension were determined by two ways. 1- From arteriovenous shunt via ventricular septal defect the correlation ratio of doppler echo cardiographic catheterization values was %76. 2- From systolic regurgitation via the tricuspid valve the correlation was %97.

Obesity As A Risk Factor For The Incidence Pregnancy Induced Hypertension (P.I.H.)

In this study 500 obese pregnant women and 250 non-obese pregnant women (Group of Control) were followed up to prove the role of obesity as a high risk factor on the incidence of (P.I.H.). We found that: 1. There is a considerable increase in the incidence of (P.I.H.), which was proportional to the grade of obesity in the main group. The incidence of P.I.H. was : %15.38 in grade 1, %26.42 in grade 2 and %42.22 in grade 3 of obesity (Vs. %6.4 in the control group). 2. There is a considerable increase in the incidence of (P.I.H.) among the obese pregnant women, especially when they are 36-45 years old (%32.39 Vs. %6.45 in control group). So that it is advisable to screen all obese pregnant women especially when they are 36-45 years old and consider them as a high risk group for the indicence of (P.I.H.).
