Observations on Aberrant Renal Arteries Curving Around and Compressing the Renal Vein

Observations on aberrant renal arteries curving around and compressing the renal vein; possible relationship to orthostatic proteinuria and to orthostatic hypertension.

Observations on Aberrant Renal Arteries Curving Around and Compressing the Renal Vein

DETAILED descriptions of frequent and multiform variations of the vascular elements of the renal pedicle are to be found in the literature.1-9 The subject has recently been well reviewed by Merklin and Michaels.1'" Embryologic interpretations of such variations have been given by Broman,11 Jeidel,'2 Felix,'3 and Bremer.'4 It is the purpose of the present work to describe a type of aberrant rena...

Anatomical Evaluation of Renal Arteries and Veins in Kidney Donors by CT Angiography

Abstract Background: Renal transplantation (RT) is the transplantation of a kidney into a patient with end-stage renal disease and has become the treatment of choice for most patients with end-stage renal disease. The knowledge of renal vascular variations is of a great importance for the surgeons who approach the kidneys from the retroperitoneal o...

Numerical 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...

Renin-dependent hypertension caused by nonfocal stenotic aberrant renal arteries: proof of a new syndrome.

We have identified 2 relatively young patients with significant hypertension, an elongated single aberrant renal artery supplying blood to a renal segment, and evidence for localization of the elevated plasma renin activity to the side and vein draining the affected kidney. Furosemide-induced diuresis and acute oral captopril stimulated the renal vein/contralateral renin ratios to 4.3:1 and 6.5...
