Hemodynamic Characteristics of Cerebral Arteriovenous Malformation Feeder Vessels With and Without Aneurysms.
BACKGROUND AND PURPOSE The pathogenesis of aneurysms associated with cerebral arteriovenous malformation (AVM) feeder vessels is poorly understood. We sought to determine the hemodynamic characteristics of AVM feeder vessels with and without aneurysms. METHODS Patients with AVMs associated with feeder aneurysms who had flow, vessel diameter, and wall shear stress measured before treatment usi...
متن کاملDirect continuous measurement of draining vein pressure during Onyx embolization in a swine arteriovenous malformation model.
OBJECTIVE Periprocedural intracranial hemorrhage secondary to intranidal flow redirection may develop after arteriovenous malformation (AVM) embolization. We hypothesized that continuous draining vein pressure monitoring may identify clinically relevant hemodynamic changes during devascularization. Our goal was to characterize the draining vein pressures in a swine rete mirabile AVM model durin...
متن کاملSpecific transcranial Doppler flow findings related to the presence and site of arterial occlusion.
BACKGROUND AND PURPOSE Transcranial Doppler (TCD) can localize arterial occlusion in stroke patients. Our aim was to evaluate the frequency of specific TCD flow findings with different sites of arterial occlusion. METHODS Using a standard insonation protocol, we prospectively evaluated the frequency of specific TCD findings in patients with or without proximal extracranial or intracranial occ...
متن کاملPressure changes within the sac of human cerebral aneurysms in response to artificially induced transient increases in systemic blood pressure.
Formation and rupture of cerebral aneurysms have been associated with chronic hypertension. The effect of transient increase in blood pressure and its effect on intra-aneurysmal hemodynamics have not been studied. We examined the effects of controlled increases in blood pressure on different pressure parameters inside the sac of human cerebral aneurysms and corresponding parent arteries using i...
متن کاملPreliminary experience with intra-arterial nicardipine as a treatment for cerebral vasospasm.
BACKGROUND AND PURPOSE Papaverine is the primary intra-arterial (IA) treatment for vasospasm after aneurysmal subarachnoid hemorrhage (SAH); however, is it limited in effect and by adverse effects. We prospectively studied the use of IA nicardipine as a treatment for vasospasm. METHODS Over 12 months, all patients with SAH who required interventional treatment for vasospasm were given IA nica...
