Summary
Older age, severe hemorrhage, and specific aneurysm locations are key risk factors for developing chronic hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH). These findings help identify patients needing closer monitoring for this serious complication.
Area of Science:
- Neurosurgery
- Neurology
- Clinical Medicine
Background:
- Aneurysmal subarachnoid hemorrhage (aSAH) can lead to serious complications, including chronic hydrocephalus.
- Identifying predisposing factors for chronic hydrocephalus post-aSAH is crucial for patient management and prognosis.
- Understanding these factors aids in risk stratification and targeted interventions.
Purpose of the Study:
- To investigate and discuss the predisposing factors associated with the development of chronic hydrocephalus following aneurysmal subarachnoid hemorrhage (aSAH).
- To identify specific clinical characteristics that increase the risk of chronic hydrocephalus in aSAH patients.
Main Methods:
- Retrospective analysis of clinical data from 32 patients treated surgically for chronic hydrocephalus after aSAH.
- Comparison of incidence rates of chronic hydrocephalus based on patient age, Hunt-Hess grade, aneurysm location, hemorrhage frequency, and presence of ventricle hematocele.
Main Results:
- Patients over 60 years old, with Hunt-Hess grade III-IV, posterior circulation or anterior communicating artery aneurysms, multiple hemorrhages, or ventricle hematocele showed a significantly higher incidence of chronic hydrocephalus.
- Conversely, younger patients (below 60), with Hunt-Hess grade I-II, aneurysms elsewhere, single hemorrhage, and no ventricle hematocele had a lower incidence.
- Statistical significance (P < 0.05) was observed for these differentiating factors.
Conclusions:
- Advanced age (>60 years), severe clinical presentation (Hunt-Hess III-IV), specific aneurysm locations (posterior circulation, anterior communicating artery), recurrent hemorrhages, and ventricle hematocele are significant predisposing factors for chronic hydrocephalus after aSAH.
- These identified factors are critical for predicting the risk of developing chronic hydrocephalus in patients with aSAH.

01:17Hemorrhagic Stroke l: Introduction
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...
01:29Hemorrhagic Stroke ll: Pathophysiology
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...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
