Homocysteine and pulsatility index of cerebral arteries.
BACKGROUND AND PURPOSE A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke. METHODS Consecutive patients with ischemic stroke referred to a neurovascular ultrasound laboratory were evaluated...
متن کاملRelationship between Pulsatility Index and Clinical Course of Acute Ischemic Stroke after Thrombolytic Treatment
Background. The relationship between the arterial recanalization after intravenous recombinant tissue plasminogen activator (rtPA) and outcomes is still uncertain. The aim of our study was to evaluate whether there is an association between the pulsatility indexes (PI) of the middle cerebral artery (MCA) measured by transcranial Doppler (TCD) after iv rtPA treatment and short- and long-term out...
متن کاملArterial pulsatility as an index of cerebral microangiopathy in diabetes.
BACKGROUND AND PURPOSE This study was designed to evaluate cerebral hemodynamic changes related to diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). METHODS We measured the flow velocities and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA), extracranial internal carotid artery (ICA), and basilar artery (BA) in 56 stroke-free, normotensive patients...
متن کاملEchocardiographic Assessment of Pulmonary Arteries Pulsatility Index in Fontan Circulation
BACKGROUND Late complications after Fontan procedure may be due to the absence of pump and pulsatile pulmonary blood flow in this type of palliation. Our aim was to quantify the degree of pulsation by echocardiographic method in patients with extracardiac total cavopulmonary connection (ECTCPC) in comparison with biventricular circulation and few cases of pulsatile Fontan. METHODS In a case s...
متن کاملBrain pulsatility and pulsatile tinnitus: clinical types.
The purpose of this commentary is to share our evolving clinical experience with the tympanic membrane displacement (TMD) analyzer which has focused on brain pulsatility in nonpulsatile, predominantly centraltype severe disabling subjective idiopathic tinnitus (SIT) patients resistant to attempts for tinnitus relief with instrumentation or medication. One outcome of this evolving TMD experience...
