Summary
C1C2-stabilization surgery carries risks of hemodynamic stroke, especially with poor posterior circulation and vertebral artery (VA) compression. Early detection of these risk factors using computed tomography angiography and intraoperative ultrasound can prevent this complication.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Radiology
Background:
- C1C2-stabilization surgery can lead to serious complications like arterial embolism, injury, and hemodynamic stroke.
- Hemodynamic stroke during C1C2-stabilization is associated with poor posterior fossa collateralization and vertebral artery (VA) compression.
Purpose of the Study:
- To report a clinical case of hemodynamic stroke during C1C2-stabilization.
- To highlight the importance of preoperative and intraoperative imaging in preventing this rare complication.
Main Methods:
- A 72-year-old patient with rheumatoid arthritis underwent C1C2-stabilization for subluxation.
- Preoperative computed tomography angiography (CTA) revealed poor posterior fossa collaterals.
- Intraoperative Doppler ultrasound (US) detected unilateral VA occlusion during reduction, prompting surgical decompression.
Main Results:
- The patient presented with risk factors for hemodynamic stroke: poor collateralization and intraoperative VA compression.
- Surgical decompression of osteofibrous elements resolved the VA occlusion, restoring normal flow.
- The C1C2-stabilization was successfully completed with favorable clinical and radiological outcomes.
Conclusions:
- Precise analysis of preoperative CTA and intraoperative US is crucial for identifying hemodynamic stroke risk factors in C1C2-stabilization.
- Proactive identification and management of these risks can prevent potentially life-threatening hemodynamic stroke complications.

01:29Hemorrhagic Stroke ll: Pathophysiology
7
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

01:17Hemorrhagic Stroke l: Introduction
5
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:15Ischemic Stroke ll: Pathophysiology
5
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

01:29Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
