Insights
Older age, poor admission grade, intraventricular hemorrhage, and meningitis predict shunt-dependent hydrocephalus after aneurysmal subarachnoid hemorrhage (SAH). Identifying these factors aids neurosurgeons in improving patient outcomes.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Hydrocephalus is a frequent complication of aneurysmal subarachnoid hemorrhage (SAH).
- Patients developing hydrocephalus post-SAH generally experience poorer prognoses.
- Identifying predictive factors for shunt-dependent hydrocephalus is crucial for patient management.
Purpose of the Study:
- To identify factors predicting the development of shunt-dependent chronic hydrocephalus in patients with aneurysmal SAH.
- To determine predictors for patients requiring permanent cerebrospinal fluid diversion after SAH.
Main Methods:
- Retrospective study of 734 patients with aneurysmal SAH treated surgically (1990-2006).
- Hydrocephalus categorized into acute (0-3 days), subacute (4-13 days), and chronic (≥14 days) post-SAH.
- CT scan criteria for hydrocephalus included enlarged temporal horns or frontal horn to biparietal diameter ratio >30%.
Main Results:
- 8.9% (66/734) of patients required shunting for chronic hydrocephalus.
- Significant predictors for shunt-dependent hydrocephalus included: increased age, poor Hunt and Hess grade, intraventricular hemorrhage, Fisher grade III/IV, radiological hydrocephalus at admission, and post-surgery meningitis.
- Intracerebral hemorrhage, multiple aneurysms, vasospasm, gender, and aneurysm location in the posterior circulation did not significantly influence the development of shunt-dependent hydrocephalus.
Conclusions:
- The etiology of hydrocephalus following aneurysmal SAH is multifactorial.
- Understanding predisposing factors for shunt-dependent chronic hydrocephalus can guide neurosurgeons toward improved treatment strategies and outcomes.
Objective:
Hydrocephalus is a common sequelae of aneurysmal subarachnoid hemorrhage (SAH) and patients who develop hydrocephalus after SAH typically have a worse prognosis than those who do not. This study was designed to identify factors predictive of shunt-dependent chronic hydrocephalus among patients with aneurysmal SAH, and patients who require permanent cerebrospinal fluid diversion.
Methods:
Seven-hundred-and-thirty-four patients with aneurysmal SAH who were treated surgically between 1990 and 2006 were retrospectively studied. Three stages of hydrocephalus have been categorized in this paper, i.e., acute (0-3 days after SAH), subacute (4-13 days after SAH), chronic (>/=14 days after SAH). Criteria indicating the occurrence of hydrocephalus were the presence of significantly enlarged temporal horns or ratio of frontal horn to maximal biparietal diameter more than 30% in computerized tomography.
Results:
Overall, 66 of the 734 patients (8.9%) underwent shunting procedures for the treatment of chronic hydrocephalus. Statistically significant associations among the following factors and shunt-dependent chronic hydrocephalus were observed. (1) Increased age (p < 0.05), (2) poor Hunt and Hess grade at admission (p < 0.05), (3) intraventricular hemorrhage (p < 0.05), (4) Fisher grade III, IV at admission (p < 0.05), (5) radiological hydrocephalus at admission (p < 0.05), and (6) post surgery meningitis (p < 0.05) did affect development of chronic hydrocephalus. However the presence of intracerebral hemorrhage, multiple aneurysms, vasospasm, and gender did not influence on the development of shunt-dependent chronic hydrocephalus. In addition, the location of the ruptured aneurysms in posterior cerebral circulation did not correlate with the development of shunt-dependent chronic hydrocephalus.
Conclusion:
Hydrocephalus after aneurysmal SAH seems to have a multifactorial etiology. Understanding predisposing factors related to the shunt-dependent chronic hydrocephalus may help to guide neurosurgeons for better treatment outcomes.
