Clinically relevant animal models of intracerebral hemorrhage (ICH) are needed to extend our knowledge of hemorrhagic stroke and to examine novel therapeutic strategies. In this study, we describe and evaluate two ICH models that implement unilateral injections of either autologous whole blood or bacterial collagenase into the basal ganglia (corpus striatum) of mice.

The autologous blood injection model of intracerebral hemorrhage in mice described in this protocol uses the double injection technique to minimize risk of blood reflux up the needle track, no anticoagulants in the pumping system, and eliminates all dead space and expandable tubing in the system.

Preclinical models of intracerebral hemorrhage are utilized to mimic certain aspects of clinical disease. Thus, mechanisms of injury and potential therapeutic strategies may be explored. In this protocol, two models of intracerebral hemorrhage are described, intrastriatal (basal ganglia) injections of autologous blood or collagenase.

Establishing a Subarachnoid Hemorrhage Rat Model Induced by Autologous Blood Injection

This video demonstrates the procedure for establishing a subarachnoid hemorrhage rat model. An anesthetized rat is implanted with probes to measure intracranial pressure and cerebral blood flow. The target site is identified, and the needle is inserted at a pre-chiasmatic position. Autologous blood is then injected into the subarachnoid space, increasing intracranial pressure and decreasing cerebral blood flow, establishing the model.
FAQs
A clot can occupy space within brain tissue, producing mass effect and contributing to increased intracranial pressure. Blood accumulation can also promote inflammation, which may worsen injury beyond the original hemorrhage. Reducing the clot burden is therefore intended to limit these secondary effects, while the surrounding neural structures remain a central concern during treatment planning.
Hemorrhage size, anatomical location, and accessibility strongly influence whether evacuation is considered and which approach may be suitable. A clot that is difficult to reach may require a different strategy from one that can be accessed directly. These factors help clinicians balance the potential benefit of reducing pressure and blood burden against the need to preserve nearby brain tissue.
Evacuation must address the harmful effects of accumulated blood without adding injury to functional brain regions. The selected route and technique are consequently evaluated in relation to the hemorrhage’s position and accessibility. This balance is especially important in neuroscience, where protection of surrounding neural structures is closely linked to the possibility of functional recovery after hemorrhagic stroke.
These approaches differ mainly in how clinicians reach and remove the clot. Craniotomy provides a surgical route through the skull, whereas minimally invasive catheter-based aspiration uses a catheter to access and aspirate blood. Endoscopic techniques use an endoscope for access and visualization. The hemorrhage’s size, location, and accessibility help determine which option is appropriate.
Planning begins with neuroimaging to characterize the hemorrhage and assess its size, location, and accessibility. Clinicians then select a suitable evacuation approach while considering protection of surrounding neural structures. The procedure is coordinated with intensive medical management, including measures to stabilize the patient and control bleeding risk before, during, and after treatment.
Researchers study these strategies to improve selection of surgical candidates and to understand which treatment choices may support functional recovery. Comparisons among craniotomy, catheter-based aspiration, and endoscopic techniques can be examined alongside hemorrhage characteristics and clinical management. This work connects operative decision-making with broader neuroscience questions about secondary injury and recovery after brain hemorrhage.
