Variations in human renal arteries
Kidneys are especially irrigated by a pair of arteries originated from the aorta artery. The presence of additional renal arteries is the most frequent variation in this vascularization, an aspect important to be known in renal surgeries and radiological procedures (SAMPAIO; PASSOS, 1992). This study aimed to observe the prevalence of numeric variation and the origin of the additional renal art...
متن کاملMultiple renal arteries: variations demonstrated by multidetector computed tomography angiography.
OBJECTIVE To present a case of a rare variation of the renal artery and multiple (7) renal arteries by multidetector computed tomography (MDCT) angiography. CLINICAL PRESENTATION AND INTERVENTION A 36-year-old male patient was admitted to our hospital as a potential living donor for renal transplantation. An MDCT angiography was performed using a 16-detector row CT scanner to obtain a detaile...
متن کاملNumerical Investigation of Angulation Effects in Stenosed Renal Arteries
Background: Numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers.Objective: This paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow.Method: An anatomically realistic model of abdominal aorta and renal arteries is reconstructed from CT-scan images and u...
متن کاملVasoactivity of diadenosine polyphosphates in human small renal resistance arteries.
BACKGROUND We examined for the first time the vascular effects of purinergic agents that contribute to the regulation of peripheral vascular resistance in human small renal resistance arteries (hRRAs). METHODS AND RESULTS Diadenosine polyphosphates (ApnAs, n = 3-6) and ATP, mounted in a microvessel myograph, caused vasoconstriction in hRRAs (rank order of potency: Ap5A > Ap6A = Ap4A > Ap3A = ...
متن کاملAnatomical variations in the coronary arteries.
The following are observations on 500 consecutive cases of coronary angiographical studies carried out on patients without any case history of myocardial ishcemia. There were 251 males and 249 females. The patients' average age was 45 years old.
