[The vascular microbasins of the human cerebral cortex]

Area of Science:

• Neuroanatomy
• Vascular Anatomy

Context:

• Understanding the intricate venous drainage system of the brain is crucial for interpreting neuroimaging and understanding neurological conditions.
• The topographical organization of cerebral veins influences tissue perfusion and waste removal.

Purpose:

• To describe the topographical organization and geometric characteristics of cerebral microbasins formed by intraorganic venous tributaries.
• To analyze the branching patterns of cortical and corticomedullary arteries within these microbasins.
• To evaluate the connectivity of adjacent microbasins via capillary networks.

Summary:

• Cerebral microbasins are topographical units formed by cortical, subcortical, and transcortical veins.
• These microbasins exhibit pyramidal shapes with characteristic venous branching patterns resembling a 'herring bone'.
• Continuous capillary networks unite adjacent microbasins, supporting the concept of a vascular continuum.

Impact:

• Provides a detailed anatomical framework for understanding cerebral venous architecture.
• Offers insights into the relationship between vascular topography and microcirculation.
• Contributes to the validation of continuum theories in vascular biology.
