Thesis Abstract
Abstract
Hemorrhagic stroke, characterized by bleeding in the brain, is a significant cause of morbidity and mortality worldwide. While arterial circulation has traditionally received more attention in stroke research, recent studies have highlighted the crucial role of the cerebral venous system in hemorrhagic stroke pathophysiology. This research abstract aims to summarize the current understanding of the role of the cerebral venous system in hemorrhagic stroke. The cerebral venous system plays a critical role in regulating intracranial pressure, cerebral blood flow, and maintaining brain homeostasis. Disruption of venous drainage can lead to venous congestion, increased capillary pressure, and ultimately to hemorrhage. Cerebral venous thrombosis, a condition characterized by the formation of blood clots in the venous sinuses, can result in venous infarction or hemorrhage due to increased capillary pressure and impaired drainage. Moreover, venous hypertension, often associated with conditions such as dural arteriovenous fistulas or venous sinus stenosis, can lead to rupture of small vessels and hemorrhage. The venous system's role in hemorrhagic stroke is further underscored by studies demonstrating that venous collagenosis and fibrosis can weaken venous walls, predisposing them to rupture under increased pressure. Importantly, cerebral venous anatomy also influences the pattern and extent of hemorrhage in different brain regions. For example, hemorrhages in the basal ganglia are often associated with deep venous system involvement, while lobar hemorrhages may result from cortical venous reflux or venous hypertension. Understanding the specific venous drainage patterns in different brain regions is crucial for predicting and managing hemorrhagic strokes effectively. In addition to its direct role in hemorrhage pathophysiology, the cerebral venous system interacts with other vascular components, such as arterial circulation and the glymphatic system. Disruption of venous drainage can impact arterial perfusion, exacerbating ischemic conditions that may coexist with hemorrhagic stroke. Furthermore, impaired glymphatic clearance due to venous congestion can lead to protein accumulation and neuroinflammation, contributing to secondary brain injury after hemorrhagic stroke. In conclusion, the cerebral venous system plays a multifaceted role in hemorrhagic stroke pathophysiology, influencing both the primary hemorrhage mechanisms and secondary brain injury processes. Further research focusing on venous hemodynamics, imaging modalities, and therapeutic strategies targeting venous dysfunction is warranted to improve outcomes in patients with hemorrhagic stroke.

</p><div><p>Currently, neuroprotective strategies mainly aim to decrease bleeding from cerebral arteries and protect the insulted neurons in the hemorrhagic stroke. However, the role of cerebral venous system in the pathophysiology of hemorrhagic stroke remains unclear. In this chapter, we summarize the relationship between cerebral venous system and hemorrhagic stroke, and aim to improve the diagnosis and management of hemorrhagic stroke by using multidisciplinary treatment approach. With several cases, including venous cavernoma, developmental venous anomalies, etc., presented in this chapter, the management of hemorrhagic stroke should be expanded from the cerebral arterial system to the balance between the cerebral arterial system and the cerebral venous system. Our aim is to establish an integrative concept in the clinical management of hemorrhagic stroke.</p><p>Keywords: Cerebral venous system Hemorrhagic stroke Intracerebral hemorrhage Venous cavernoma Developmental venous anomalies</p><p><strong>References</strong></p><p>1.
