Venous intracerebral hemorrhage hypotheses: Hydrostatic pressure-induced bleeding mechanism and comparative analysis with arterial hemorrhage

This study establishes a hypothesis on cerebral venous thrombosis (CVT)-induced intracerebral hemorrhage (ICH), emphasizing distinctive computer tomography (CT) imaging features indicative of venous origin hemorrhages—characterized by lower CT values, diffuse cloud-like appearances, and indistinct borders, attributed to the dynamics of venous bleeding and plasma-dominated blood composition. It further delineates the unique propagation pattern of venous ICH, favoring slow diffusion through white matter tracts rather than entering sulci or breaching the arachnoid membrane, and highlights the susceptibility of specific brain regions due to their venous architecture. Contrasting these findings with arterial ICH, the paper argues for the need for tailored diagnostic and therapeutic approaches. It concludes with a discussion on future research directions, focusing on the development of novel diagnostic tools and treatment modalities specific to venous ICH.
