Pre-Chiasmatic, Single Injection of Autologous Blood to Induce Experimental Subarachnoid Hemorrhage in a Rat Model09:14

Pre-Chiasmatic, Single Injection of Autologous Blood to Induce Experimental Subarachnoid Hemorrhage in a Rat Model

Subarachnoid hemorrhage continues to carry a high burden of mortality and morbidity in man. To facilitate further research into the condition and its pathophysiology, a pre-chiasmatic, single injection model is...

Double Direct Injection of Blood into the Cisterna Magna as a Model of Subarachnoid Hemorrhage10:34

Double Direct Injection of Blood into the Cisterna Magna as a Model of Subarachnoid Hemorrhage

We described in this protocol a standardized subarachnoid hemorrhage (SAH) mouse model by a double injection of autologous whole-blood into the cisterna magna. The high degree of standardization of the double-injection procedure represents a middle-to-acute model of SAH with relative safety regarding...

A Murine Model of Subarachnoid Hemorrhage07:40

A Murine Model of Subarachnoid Hemorrhage

A standardized mouse model of subarachnoid hemorrhage by intraluminal Circle of Willis perforation is described. Vessel perforation and subarachnoid bleeding are monitored by intracranial pressure monitoring. In addition various vital parameters are recorded and controlled to maintain physiologic...

A Low Mortality Rat Model to Assess Delayed Cerebral Vasospasm After Experimental Subarachnoid Hemorrhage

Aneurysmal subarachnoid hemorrhage (SAH) is bleeding that occurs into the subarachnoid space when an aneurysm ruptures. While the morbidity and mortality from this event has been on a decline due to improved treatment approaches, the risk of vasospasm after subarachnoid hemorrhage continues to be the same as it was several years ago. The importance of establishing a comprehensive and reproducible animal model to identify initiating events of cerebral vasospasm has been the focus of research...

Induction of a Subarachnoid Hemorrhage in a Mouse Model through Endovascular Perforation04:43

Induction of a Subarachnoid Hemorrhage in a Mouse Model through Endovascular Perforation

The video demonstrates the induction of subarachnoid hemorrhage via endovascular perforation in a mouse model. An incision is made in the neck region of the anesthetized mouse to access the common carotid artery and its bifurcation. A filament is inserted through the arteries to perforate an intracranial artery branch, inducing subarachnoid...

A Volumetric Method for Quantification of Cerebral Vasospasm in a Murine Model of Subarachnoid Hemorrhage

The goal of this article is to present a method that allows a 3-dimensional reconstruction of the cerebrovascular tree in mice after micro computed tomography and determination of volumes of entire vessel segments that can be used to quantify cerebral vasospasm in murine models of subarachnoid...
