Arterial 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 کاملHomocysteine 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 کاملLacunar Infarction in Type 2 Diabetes Is Associated with an Elevated Intracranial Arterial Pulsatility Index
PURPOSE The arterial pulsatility index (PI) is measured by transcranial Doppler ultrasonography (TCD) and is postulated to reflect the vascular resistance distal to the artery being examined. An increased PI of the intracranial artery is often reported with diabetes mellitus (DM), old age, hypertension, intracranial hypertension, vascular dementia, and small artery disease. Microvascular compli...
متن کاملIncreased cerebral arterial pulsatility in patients with leukoaraiosis: arterial stiffness enhances transmission of aortic pulsatility.
BACKGROUND AND PURPOSE Arterial stiffening reduces damping of the arterial waveform and hence increases pulsatility of cerebral blood flow, potentially damaging small vessels. In the absence of previous studies in patients with recent transient ischemic attack or stroke, we determined the associations between leukoaraiosis and aortic and middle cerebral artery stiffness and pulsatility. METHO...
متن کاملCerebral microangiopathy in patients with non-insulin-dependent diabetes mellitus.
INTRODUCTION The aim of the study was to evaluate cerebral microangiopathy in type 2 noninsulin- dependent diabetes mellitus (NIDDM) patients and to establish potentially conducive factors. MATERIALS AND METHODS A group of 34 patients with NIDDM and 31 gender- and agematched normal controls (NC) were assessed by extracranial Doppler ultrasound, in order to evaluate the pulsatility index (PI) ...
