Local hemodynamics of the vascular access for hemodialysis.
Vascular access is called Achilles' heel of hemodialysis because it is associated with a substantial morbidity. A permanent vascular access is created either by a direct connection of the patient's own artery and vein or by the interposition of a graft. Arteriolar beds are bypassed, which leads to a substantial increase in arterial (and venous) flow and the vessels adapt to it by a complex of i...
متن کاملAnti-TNFα therapy early improves hemodynamics in local intestinal and extraintestinal circulations in active Crohn's disease.
BACKGROUND AND AIMS Active Crohn's disease affects intestine but may alter other locations as eyes vasculature. Previous studies provide evidence of elevated blood flow velocities (BFv) and volume (BFV) in superior mesenteric artery (SMA). We prospectively studied hemodynamics in feeding arteries of bowel and eyes before and 2 weeks after treatment induction with anti-TNFα. METHODS Fifteen pa...
متن کاملLocal hemodynamics dictate long-term dendritic plasticity in peri-infarct cortex.
Changes in dendritic spine turnover are a major mechanism of experience-dependent plasticity in the adult neocortex. Dendritic spine plasticity may also contribute to functional recovery after stroke, but in that setting its expression may be complicated by alterations in local tissue perfusion, especially around the infarct. Using adult Thy-1 GFP-M mice, we simultaneously recorded long-term sp...
متن کاملOn the influence of vessel planarity on local hemodynamics at the human carotid bifurcation.
The human carotid artery bifurcation is a complex, three-dimensional structure exhibiting non-planarity and both in- and out-of-plane curvature. The aim of this study was to determine the relative importance of vessel planarity, a potential geometric risk factor for atherogenesis, in determining the local hemodynamics. A combination of computational fluid dynamics and magnetic resonance imaging...
متن کاملEffect of chronic middle cerebral artery stenosis on the local cerebral hemodynamics.
In 36 patients with angiographically proven middle cerebral artery (MCA) stenosis, local cerebral hemodynamics were studied employing angiography, 133Xe inhalation regional cerebral blood flow (rCBF) measurements and CT scans. They had transient ischemic attacks in 8 and completed stroke in 28. The patients with less than 50% stenosis (n = 16) had no hemodynamic abnormality in angiographical an...
