Since our initial experience on April 28, 1989, a total of nine patients have received treatment for giant cerebral aneurysm using cardiopulmonary bypass with deep hypothermia and circulatory arrest. The following data summarize our findings associated with these patients. The average patient's age

A 55-year-old woman underwent emergency cerebral aneurysm clipping for subarachnoid hemorrhage (SAH). Her past and family history was unremarkable. Preoperative blood examinations were within normal ranges except for a slight decrease in serum potassium level. ECG showed a prolonged QTc interval

The aim of the study is to investigate the value of serum iron and hemoglobin levels for predicting acute seizures following aneurysmal subarachnoid hemorrhage (aSAH).Clinical and laboratorial data from patients with ruptured intracranial aneurysms were

Vasoconstrictor activity was examined in serial samples of cerebrospinal fluid (CSF) obtained from 10 patients undergoing aneurysm clipping within 48 hours after subarachnoid hemorrhage (SAH). There was no close relationship between vasoconstrictor activity in postoperative CSF samples and the

We have previously shown the safety and efficacy of University of Wisconsin solution for hypothermic preservation of the human donor heart in a pilot group of 16 transplant recipients. The present study is a randomized clinical trial comparing University of Wisconsin solution to conventional

Changes in level of consciousness and association with hyperglycemia as tool for predicting and preventing re-bleeding after spontaneous subarachnoid hemorrhage.

BACKGROUND It is crucial to predict and prevent re-bleeding from ruptured intracranial aneurysms in patients with subarachnoid hemorrhage (SAH). During the prehospital period and on arrival to the hospital, blood glucose and serum potassium levels, as well as changes in levels of consciousness were

Although its status as a neuroprotectant is controversial, etomidate is often employed for pharmacologic cerebral protection in aneurysm surgery. One purported advantage of etomidate over thiopental is its hemodynamic stability. This study examined the cardiovascular effects of etomidate given for

Vasoconstrictive effects of human post-hemorrhagic cerebrospinal fluid on cat pial arterioles in situ.

Logga in Bli medlem

Cat cortical arterioles were exposed in vivo to cerebrospinal fluid (CSF) from four patients with subarachnoid hemorrhage (SAH) due to a ruptured intracranial aneurysm. Pial arteriolar caliber was measured by the television image-splitting technique. There was a consistent vasoconstrictive response

Cerebrovascular dysfunction after subarachnoid haemorrhage: novel mechanisms and directions for therapy.

1. When a cerebral aneurysm ruptures, bleeding and clot formation occur around the surface of the brain, including several major blood vessels. The resulting condition, known as subarachnoid haemorrhage (SAH), often results in death or severe disability and is a significant cause of stroke. Delayed

1. Despite extensive research no explanation has been put forward to account for the fact that cerebral arterial spasm complicates the course of disease of many but not all patients suffering from rupture of an intracranial aneurysm. Although vasoactive material in hemorrhagic cerebrospinal fluid

Isolated human superficial temporal arteries were constricted by the addition of potassium, norepinephrine, and 5-hydroxytryptamine. Different responses occurred when the vessels were taken from patients with ruptured intracranial aneurysm and from patients without cerebral aneurysm. In the aneurysm
