What is the surgical management for a patient with extensive subarachnoid hemorrhage and intraventricular hemorrhage, presenting with signs of hydrocephalus, suggestive of a ruptured aneurysm, and accompanied by right frontal and temporal brain edema, as well as pansinusitis (inflammation of the paranasal sinuses)?

From the Guidelines

Surgical management for extensive subarachnoid hemorrhage with intraventricular hemorrhage, hydrocephalus, suspected aneurysm rupture, right frontal/temporal brain edema, and pansinusitis requires immediate neurosurgical intervention, prioritizing early treatment of the ruptured aneurysm to reduce the risk of rebleeding and facilitate treatment of delayed cerebral ischemia, as supported by the 2023 guideline from the American Heart Association/American Stroke Association 1. The patient should undergo emergency external ventricular drain (EVD) placement to manage hydrocephalus, as persistent or chronic shunt-dependent hydrocephalus occurs in 8.9% to 48% of patients with aSAH, with significant predictors including poor admission neurological grade, increased age, acute hydrocephalus, high Fisher grades, presence of intraventricular hemorrhage, rebleeding, ruptured posterior circulation artery aneurysm, anterior communicating artery aneurysm, surgical clipping, endovascular coiling, cerebral vasospasm, meningitis, and a prolonged period of EVD 1.

Key Interventions

• Emergency EVD placement to manage hydrocephalus
• Cerebral angiography to locate the aneurysm
• Subsequent surgical clipping or endovascular coiling of the aneurysm, with the goal of complete obliteration whenever feasible, as incomplete obliteration is associated with a higher risk of rebleeding and retreatment 1
• Osmotic therapy with mannitol (0.25-1g/kg IV q4-6h) or hypertonic saline (3% solution at 0.5-1mL/kg/hr) for brain edema
• Nimodipine 60mg orally every 4 hours for 21 days to prevent vasospasm
• Seizure prophylaxis with levetiracetam 500mg IV/PO twice daily
• Broad-spectrum antibiotics such as vancomycin 15-20mg/kg IV q8-12h plus ceftriaxone 2g IV daily for 10-14 days to treat pansinusitis

Monitoring and Supportive Care

• Close neurological monitoring in an ICU setting with frequent neurological examinations
• Transcranial Doppler studies to detect vasospasm
• Blood pressure maintenance below 160/90 mmHg using labetalol or nicardipine if needed This comprehensive approach addresses the life-threatening hemorrhage, prevents secondary complications, and treats the concurrent sinus infection to optimize patient outcomes, in line with the recommendations from the 2023 guideline for the management of patients with aneurysmal subarachnoid hemorrhage 1.

Surgical Management

The surgical management for a patient with extensive subarachnoid hemorrhage and intraventricular hemorrhage, presenting with signs of hydrocephalus, suggestive of a ruptured aneurysm, and accompanied by right frontal and temporal brain edema, as well as pansinusitis, involves several key considerations:

• External ventricular drainage (EVD) is a crucial intervention for managing hydrocephalus, especially if it is contributing to a neurologic decline 2, 3, 4.
• The placement of an EVD should be done with caution, as it may increase the transmural pressure difference across the wall of a ruptured cerebral aneurysm and precipitate rerupture 2.
• In patients with acute aneurysmal subarachnoid hemorrhage, EVD is associated with a relatively low risk of infectious, liquorodynamic, and hemorrhagic complications and does not worsen outcomes when used before surgery 4.
• The decision to perform EVD should be tailored to the individual patient's needs, taking into account the severity of hydrocephalus, the presence of intracerebral hemorrhage, and the patient's overall clinical condition 3.

Treatment of Hydrocephalus

The treatment of hydrocephalus in this context may involve:

• Temporary EVD, which can be weaned according to standard protocols to determine the need for ventriculoperitoneal shunting (VPS) 5.
• Ventriculoperitoneal shunting, which may be required in patients who develop delayed, symptomatic hydrocephalus after initial EVD weaning trials 5.
• The use of fibrinolytic agents through an EVD, which may be considered in patients with intraventricular hemorrhage causing or threatening to cause obstructive hydrocephalus, although this is contraindicated in patients with unrepaired cerebral aneurysms or clotting disorders 2, 6.

Considerations for Aneurysm Repair

The repair of the ruptured aneurysm is a critical aspect of management:

• Microsurgical clipping of the aneurysm can be performed, and the use of EVD before surgery may be beneficial in reducing intracranial pressure and improving outcomes 4.
• The timing of aneurysm repair should be carefully considered, taking into account the patient's clinical condition, the severity of hydrocephalus, and the presence of other complications such as pansinusitis.
