Mechanical disorders of the cervicocerebral circulation in children and young adults

Area of Science:

• Neurology
• Vascular Medicine
• Pediatric Neurology

Background:

• Mechanical disorders of the cervicocerebral circulation (MDCC) present neurological symptoms due to external mechanical forces on extracranial blood vessels during head movement.
• The spectrum includes conditions like bow hunter's syndrome, carotid-type Eagle syndrome, and dynamic venous compression syndromes.
• Phenotypes and clinical presentations of MDCC differ significantly between children and older adults.

Purpose of the Study:

• To provide a comprehensive overview of the pathophysiology, anatomical patterns, diagnosis, and treatment of MDCC.
• To highlight the distinct features and diagnostic nuances of MDCC in children.
• To guide neuroendovascular specialists in the recognition and management of these conditions.

Main Methods:

• Review of existing literature on MDCC, including bow hunter's syndrome, Eagle syndrome, and venous compression syndromes.
• Analysis of anatomical variations and biomechanical factors contributing to MDCC.
• Discussion of diagnostic techniques and neuroimaging modalities used in evaluating MDCC.
• Synthesis of current treatment strategies for MDCC.

Main Results:

• MDCC encompasses a range of conditions caused by mechanical compression of cervicocerebral vessels during physiological head movements.
• Diagnostic evaluation requires specialized neuroendovascular expertise and technical precision, especially for pediatric patients.
• Understanding the specific anatomical patterns and pathophysiological mechanisms is crucial for accurate diagnosis and effective management.

Conclusions:

• MDCC is a significant cause of neurological symptoms related to head and neck movement, requiring specialized diagnostic approaches.
• The neuroendovascular specialist plays a key role in the diagnosis and management of MDCC, particularly in the pediatric population.
• This overview provides a foundational understanding for clinicians managing the diverse spectrum of MDCC.
