In stenosis of a segmental branch or among multiple renal arteries, Doppler sampling of intrarenal arteries in the upper, mid and lower poles demonstrates strikingly different waveform patterns that might otherwise be overlooked. We report a case of segmental branch renal artery stenosis in which a pulsus parvus et tardus waveform was observed in a segmental branch of a renal artery. In this ca...

65 years gentleman presented to emergency department with upper body hypertensive urgency, heart failure and renal shut down. He had recently undergone aortography and CT angiography which revealed severe atheromatous narrowing of upper descending thoracic aorta, well below the origin of left subclavian artery, with maximal stenosis of 85% at D5-D6 vertebrae level. Urgent aortic stenting with c...

the vascular complications, their management and results of treatment in 417 consecutive renal transplantations performed at taleghani hospital from september 1989 to december 1997, are presented. there were 7 (1.6%) vascular complications. among them renal artery stenosis occurred in 2 cases (0.4%), renal artery thrombosis in 2 cases (0.4%), renal vein thrombosis in one case (0.2%), bleeding f...

DOI: 10.5935/abc.20150013 Cardiovascular diseases are currently the major cause of morbidity and mortality. Atherosclerosis alone is their most important cause and is characterized by a progressive multifactorial disease caused by genetic and acquired factors such as lipid accumulation, development of fibrosis and artery obstruction. The risk among patients with chronic renal failure (CRF) is h...

INTRODUCTION Superior mesenteric artery syndrome is an uncommon cause of duodenal obstruction, and its manifestations are generally associated with compression on the third part of the duodenum between the abdominal aorta and superior mesenteric artery. CASE PRESENTATION In this report, a patient is described presenting with epigastric pain and weight loss due to superior mesenteric artery sy...

in this study, it has been observed that the natural similarity of the blood flow to both kidneys, despite the differences of length of the right and left renal arteries, is due to the angle of distribution of these arteries. this angle has been determined to be of 66.7 degrees for the left renal artery and only 51.5 degrees for the right renal artery, in their normal anatomical aspects.

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...

A case is reported of a patient with aberrant right renal artery arising at the level of the eleventh thoracic segment associated with renal artery aneurysm and systemic hypertension. Knowledge of the existence of aberrant renal arteries is important because they may be inadvertently damaged during renal surgery and their presence must be considered in evaluating a donor kidney for possible ren...
