The most common anatomic variant seen in donor kidneys for renal transplantation is the presence of multiple renal arteries, which can cause an increased risk of complications. Accessory renal arteries should be anastomosed to the proper source arteries to improve renal perfusion via the appropriate vascular reconstruction techniques. In microsurgery, 2 kinds of vascular augmentation methods, k...

BACKGROUND An excessive rate of cardiac death is a well-known feature of renal failure. Coronary heart disease is frequent and the possibility has been raised that the natural history of the coronary plaque is different in uraemic patients. We assessed the morphology of coronary arteries in patients with end-stage renal failure and compared them with coronary arteries of matched non-uraemic con...

The role of cytochrome P-450 in the myogenic response of isolated, perfused renal arcuate arteries of dogs to elevations in transmural pressure was examined. The phospholipase A2 inhibitor oleyloxyethylphosphorylcholine (1 and 10 ,uM) inhibited the greater than threefold increase in active wall tension in these arteries after an elevation in perfusion pressure from 80 to 160 mm Hg. Inhibition o...

BACKGROUND Children born with reduced congenital renal mass have an increased risk of hypertension and chronic kidney disease in adulthood, although the mechanisms are poorly understood. Similar sequelae occur after fetal uninephrectomy (uni-x) in sheep, leading to a 30% nephron deficit. We hypothesized that renal dysfunction is underpinned by a reduced contribution of nitric oxide (NO) and vas...

PURPOSE To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE Open arterial access is obtained to both common femoral arteries and the left subclavian artery (LSA). Access to the visceral and renal a...

Atrial natriuretic peptide is a potent dilator of aorta and renal and cerebral arteries and inhibits sympathetic tone in the heart in several mammalian species. We examined the possibility that a molecule related to porcine brain natriuretic peptide (pBNP), which acts at the same receptor sites as atrial natriuretic peptide, might provide an alternative source of natriuretic peptide to the card...

The ultrastructural distribution of the autonomic nerves of brain arteries was investigated in renal (one-kidney, one clip) hypertensive and normotensive Wistar-Kyoto rats. Sympathetic and nonsympathetic nerve terminals were found only in the adventitial layer of brain arteries of renal hypertensive and normotensive rats. In both normotensive and renal hypertensive rats the total nerve endings ...

Methods We performed vascular screening including the coronary, carotid, renal arteries and aorta using MRA (1.5 T commercial scanner, Toshiba Medical Systems Excelart Vantage TM powered by Atlas) and biochemistry tests in asymptomatic subjects from October 2008 to July 2011. Imaging of carotid arteries was performed by time of flight methods. Imaging of coronary arteries was performed by corre...

RECOGNITION of renal arterial disease as a cause of hypertension has been made possible by the development of renal arteriography. Much of the earlier experienee in diagnosis of these lesions was gained with translumbar aortography. As helpful as this technic has been in opening up an important area for clinical study, its usefulness is often limited because it does not always give sufficient d...

OBJECTIVE The aim of this study was to describe the renal arteries of humans in vivo, as precisely as possible, and to formulate an expected value for the exclusion of renal denervation due to the anatomical situation based on the criteria of the Symplicity HTN trials. DESIGN AND SETTING In a retrospective cohort study, the renal arteries of 126 patients (57 women, 69 men, mean age 60 ± 17.2 ...
