Summary of "Decrease of blood flow velocity in the middle cerebral artery after stellate ganglion block following aneurysmal subarachnoid hemorrhage: a potential vasospasm treatment?"

Cerebral vasospasm (CV) is a delayed, sustained contraction of the cerebral arteries that tends to occur 3-14 days after aneurysmal subarachnoid hemorrhage (aSAH) from a ruptured aneurysm. Vasospasm potentially leads to delayed cerebral ischemia, and despite medical treatment, 1 of 3 patients suffer a persistent neurological deficit. Bedside transcranial Doppler (TCD) ultrasonography is used to indirectly detect CV through recognition of an increase in cerebral blood flow velocity (CBFV). The present study aimed to use TCD ultrasonography to monitor how CBFV changes on both the ipsi- and contralateral sides of the brain in the first 24 hours after patients have received a stellate ganglion block (SGB) to treat CV that persists despite maximum standard therapy.

Cerebral blood flow dynamic in foetuses with hypoplastic left heart syndrome: incremental value of the first segment of the anterior cerebral artery over the middle cerebral artery?

To investigate the blood flow Doppler parameters of the anterior cerebral artery (ACA) in foetuses with hypoplastic left heart syndrome (HLHS).

Cerebrovascular regulation is not blunted during mental stress.

The effects of acute mental stress on the mechanisms regulating cerebral blood flow remain unclear. The major novel findings of this study were that: 1) high mental stress and hypercapnia had an inter...

Endovascular coil embolization of proximal middle cerebral artery aneurysms has better outcomes than other middle cerebral artery aneurysms: A retrospective study.

Although some authors proposed that coil embolization in middle cerebral artery (MCA) aneurysms is a useful and effective alternative, the characteristics of the aneurysms may be different at each loc...

Impaired Collateral Flow in Pial Arterioles of Aged Rats During Ischemic Stroke.

Cerebral collateral circulation and age are critical factors in determining outcome from acute ischemic stroke. Aging may lead to rarefaction of cerebral collaterals, and thereby accelerate ischemic i...

Internal Carotid Artery Blood Flow Response to Anesthesia, Pneumoperitoneum, and Head-up Tilt during Laparoscopic Cholecystectomy.

Cardiac output is an independent regulator of cerebral blood flow in healthy awake humansThe relationship between cardiac output and cerebral blood flow in anesthetized patients undergoing laparoscopy...

The Impact of Non-pulsatile Blood Flow on CO2-Reactivity

The investigators hypothezised that CO2-reactivity of cerebral vessels is affected by systemic non-pulsatile blood flow. Patients undergoing elective cardiac surgery with CPB were enrolled...

Risk Factors for Occurrence of the Middle Cerebral Artery Aneurysm

The aim of the research was to evaluate independent risk factors for the presence of middle cerebral artery aneurysm. Hemodynamic factors play the most important role in rupture aneurysm a...

The Effect of an α2-Adrenoceptor Antagonist (Yohimbine) on Dynamic Autoregulation in the Human Middle Cerebral Artery and Ophthalmic Artery

Blood flow autoregulation is defined as the ability of a tissue to maintain a relatively constant flow, despite moderate alterations in perfusion pressure. Similar to the cerebral, renal, ...

Fetal Doppler Indices in Predicting Perinatal Outcome Among Severely Hypertensive Pregnant Patients.

60 pregnant women with singleton living fetus between 34 -38 wks gestation known to have severe hypertension in the current pregnancy were included. All participants underwent Doppler ult...

Carbon Monoxide's Headache Inducing Characteristics and Effects on the Cerebral Arteries and Blood Flow

In this study the investigators will research the hypothesis that the gas carbon monoxide induces headache and increases the blood flow velocity in the middle cerebral artery.

Medical and Biotech [MESH] Definitions

NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.

A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.

A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.

Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.

The decrease in neuronal activity (related to a decrease in metabolic demand) extending from the site of cortical stimulation. It is believed to be responsible for the decrease in cerebral blood flow that accompanies the aura of MIGRAINE WITH AURA. (Campbell's Psychiatric Dictionary, 8th ed.)
