Renal Artery Calcium and Hypertension

23:20 EST 26th November 2014 | BioPortfolio

Summary

CT of the abdomen is a very common examination performed for various indications.One of the common findings is vascular calcifications including calcifications of the renal arteries.Calcifications in the carotid arteries and coronary arteries are good predictor for obstructive atherosclerotic disease.Stenosis of the renal arteries can cause symptomatic or asymptomatic hypertension with subsequent clinical sequelae. Therefore early diagnosis of this condition is imperative.

The goal of our study is to investigate the correlation between incidental calcifications of the renal arteries in CT examinations and the presence of actual stenosis of these vessels in patients with and without hypertension.

Description

Every patient aged 30-100 referred for abdominal CT examination with IV contrast injection will be included in this study (total 300 patients.Prior to the examination relevant clinical data including history of hypertension and predisposing conditions for atherosclerotic disease, will be investigated. The patient will undergo conventional CT with no special procedures. The images will be review by the radiologist for the presence of renal arteries calcifications, renal arteries stenosis,plaque location, plaque burden and characterization and secondary renal pathology.

This study will not change the examination technique and is not associated with any inconvenience to the patients.

Medical and Biotech [MESH] Definitions

A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.

Hypertension due to RENAL ARTERY OBSTRUCTION or compression.

Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.

A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.

A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
