Unambiguous information of vascular variation and planning of conducting surgical and radiological procedure is important during renal transplantation. During the routine dissection of a male cadaver we discovered unilateral accessory renal artery (UARA). It originated from the antero-lateral aspect of the abdominal aorta, at the level of inferior mesenteric artery (IMR) and below the renal art...
The rupture of a renal artery aneurysm is a rare disease that is difficult to diagnose. Although we usually consider the appropriate treatment to be open laparotomy with aortic aneurysm surgery or stenting with graft insertion through intravascular intervention, thus far, there is no general consensus on the treatment protocol for renal artery aneurysm. Notably, ruptured renal artery aneurysm i...
Background: In a recent study, we were able to demonstrate a role for leukocyte transfer in the induction of liver damage in recipient mice after induction of IR (60 min of bilateral renal artery occlusion and 3 hrs reperfusion) injury in donors. The present study investigates the role of leukocyte transfer in the induction of kidney damage in recipient mice after induction of renal IR injury i...
The anatomical variations of renal artery related with number, branching pattern and origin level have been well described. regarding the course are limited mainly its relation vena cava inferior. However, diaphragmatic crus is also on pathway this relationship might variations. Different from usual precrural position, there a few cadaveric dissections reported as retrocrural or transcrural art...
Randomized clinical trials have not shown an additional clinical benefit of renal artery stent placement over optimal medical therapy alone. However, studies of renal artery stent placement have not examined the relationship of albuminuria and treatment group outcomes. The CORAL study (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) is a prospective clinical trial of 947 participants ...
The objective of this study was to determine the quantitative intravascular ultrasound (IVUS) and angiographic changes that occur during 1 year follow-up after renal artery stent placement, given that restenosis continues to be a limitation of renal artery stent placement. 38 consecutive patients with symptomatic renal artery stenosis treated with Palmaz stent placement were studied prospective...
Background: The renal sympathetic nerve activity (RSNA) is enhanced in renal failure. Paraventricular nucleus in hypothalamus is an important central site to regulate sympathetic activity. There are angiotensin II (Ang) II receptors in this nucleus. The aim of this study was to evaluate the effects of angiotensin II in hypothalamic paraventricular nucleus (PVN) on renal ischemia-reperfusion inj...
Renal vascular responses to pregnancy have frequently been studied, by investigating renal vascular resistance (RVR), renal flow, glomerular filtration rate (GFR), and renal artery responses to stimuli. Nonetheless, several questions remain: 1. Which vasodilator pathways are activated and to what extent do they affect RVR, renal flow and GFR across species, strains and gestational ages, 2. Are ...
