Amongst large number of anatomical variations in the vascularization of the kidney, the most common variation is the occurrence of multiple renal arteries. The arteries play an important role in the circulatory system as they carry a large portion of blood to the kidneys. Due to very high incidence of such variations reported by previous studies, current study was conducted to observe incidence...

This is a case where multiple anomalies of the posterior abdominal wall arteries were found. These were accessory renal, a pre-hilar division of the renal, a unilateral origin of the inferior phrenic artery from the renal and aberrant suprarenal arteries. The accessory renal and the pre-hilar branch of the renal resembled polar arteries that supplied the upper and lower poles and similar segmen...

Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...

Introduction: Knowledge of presence of supernumerary renal arteries with anomalous origin of gonadal arteries are important with increased use of laparoscopic renal surgeries and donor nephrectomy. Transplantation of kidney may be jeopardized with aberrant renal and gonadal arteries. Therefore this case report will help surgeons to understand the possible abnormalities which are very important ...

Vascular resistance is increased in the kidneys of spontaneously hypertensive rats (SHR). Previous studies have demonstrated impaired vascular relaxations of mesenteric resistance arteries of SHR because of increased production of a cyclooxygenase-dependent endothelium-derived contracting factor. To test the hypothesis that altered endothelial function contributes to the enhanced constriction i...

PURPOSE To evaluate the accuracy of unenhanced magnetic resonance angiography (U-MRA) using balanced steady-state free precession (SSFP) sequences with inversion recovery (IR) pulses for the evaluation of renal artery stenosis. MATERIALS AND METHODS U-MRA was performed in 24 patients with suspected main renal artery stenosis. Two radiologists evaluated the quality of the imaging studies and t...

OBJECTIVES This study sought to assess the efficacy of catheter-based renal sympathetic denervation in patients with accessory renal arteries and to compare the blood pressure (BP)-lowering effect with that observed in patients with bilateral single renal arteries after renal denervation. BACKGROUND Catheter-based renal sympathetic denervation causes significant BP reductions in patients with...

BACKGROUND Variant anatomy of renal arteries is important in renal transplant, vascular reconstruction, and uroradiological procedures. The variations show ethnic and population differences. Data from Africans are scarce and altogether absent for Kenyans. OBJECTIVE To describe patterns of origin, trajectories and branching of renal arteries in a Kenyan population. STUDY DESIGN AND SETTING D...

Objective: To assess the histological changes of the aorta, the renal arteries and the renal parenchyma in swine, induced by a metalic uncovered stent implanted in transrenal position in the abdominal aorta. Methods: Ten pigs with a mean weight of 86.6 kg and mean age of 6 months underwent implantation of metal stent graft placed in the aorta at the level of the renal arteries after 100 days of...

The kidneys are one of the vital organs in the human body. It receives rich blood supply, nearly 25% of the cardiac output pass through the renal arteries to be filtered by the kidneys. These are end arteries with no anastomosis. Variations in the number and arrangement of the renal vessels are extremely common. The so called aberrant or accessory arteries are in fact, normal segmental arteries...
