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?

From the Guidelines

Surgical management for extensive subarachnoid hemorrhage with intraventricular hemorrhage, hydrocephalus, and suspected ruptured aneurysm requires immediate neurosurgical intervention, with a focus on early treatment of the ruptured aneurysm to reduce the risk of rebleeding and facilitate treatment of delayed cerebral ischemia, as recommended by the 2023 guideline from the American Heart Association/American Stroke Association 1.

Key Considerations

• The patient should undergo emergency external ventricular drain (EVD) placement to manage hydrocephalus, followed by cerebral angiography to identify the aneurysm location, and then definitive surgical treatment with either endovascular coiling or surgical clipping of the aneurysm.
• The goal of initial treatment is complete obliteration of the aneurysm whenever feasible, as incomplete obliteration is associated with a higher risk of rebleeding and retreatment 1.
• For patients in whom complete obliteration is not feasible, partial treatment aimed at securing the putative rupture site during the acute phase is reasonable to reduce the risk of early rebleeding, with retreatment typically within 1 to 3 months 1.

Management of Complications

• Mannitol (0.25-1g/kg IV) or hypertonic saline (3% solution at 0.5-2ml/kg/hr) should be administered to reduce brain edema, particularly in the right frontal and temporal regions.
• Blood pressure should be strictly controlled, typically maintaining systolic pressure below 140-160 mmHg using medications like nicardipine (5-15 mg/hr) or labetalol (10-80 mg/hr).
• Nimodipine 60mg every 4 hours should be started to prevent vasospasm, as recommended by the guidelines 1.
• Seizure prophylaxis with levetiracetam 500-1000mg twice daily is recommended.

Post-Operative Care

• The patient will require ICU monitoring with serial neurological examinations, transcranial Doppler studies to detect vasospasm, and gradual weaning of the EVD when appropriate.
• This comprehensive approach addresses the immediate life-threatening hydrocephalus, treats the underlying aneurysm to prevent rebleeding, and manages complications like brain edema and potential vasospasm, which are significant causes of morbidity and mortality in subarachnoid hemorrhage.

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, involves several key considerations:

• The immediate threat to life posed by intraventricular hemorrhage (IVH) is the development of acute obstructive hydrocephalus, which requires emergent treatment with external ventricular drainage (EVD) through an intraventricular catheter (IVC) if contributing to neurologic decline 2.
• In cases of IVH secondary to a ruptured cerebral aneurysm, it is advisable to delay treatment of hydrocephalus that is not contributing to a neurologic decline until the aneurysm is repaired 2.
• The placement of an EVD is widely practiced in neurosurgery for various diseases and conditions accompanied by impaired cerebrospinal fluid (CSF) circulation, intracranial hypertension (ICHyp), intraventricular hemorrhage (IVH), and hydrocephalus 3.
• EVD ensures effective monitoring and reduction of ICP and is associated with a relatively low risk of infectious, liquorodynamic, and hemorrhagic complications 3.

Treatment of Hydrocephalus

• Hydrocephalus contributing to significant neurologic decline in the setting of a ruptured aneurysm must be treated immediately despite the unprotected status of the aneurysm 2.
• Intraventricular injections of thrombolytic agents through an IVC may be considered in patients with IVH that is causing or threatening to cause obstructive hydrocephalus, but unrepaired cerebral aneurysms, untreated cerebral arteriovenous malformations, and clotting disorders are contraindications for this intervention 2.
• The surgical evacuation of IVH has a role only in very rare cases in which the IVH is causing a significant mass effect independent of hydrocephalus and associated intraparenchymal brain hemorrhage 2.

Aneurysm Repair

• Early identification and management of the bleeding source are crucial in the management of subarachnoid hemorrhage (SAH) 4.
• Evaluation and treatment decisions for unsecured aneurysms should be made by a multidisciplinary team consisting of cerebrovascular neurosurgeons, endovascular practitioners, and neurointensivists 4.
• The optimal management of hydrocephalus and intracranial pressure, as well as the role of clipping, are still unanswered questions in the management of aneurysmal subarachnoid hemorrhage 5.

Multidisciplinary Approach

• A multidisciplinary consensus panel composed of physicians with expertise in anesthesia/intensive care, neurosurgery, and interventional neuroradiology can provide practical recommendations for the management of SAH patients in hospitals with neurosurgical/neuroendovascular facilities until aneurysm securing 6.
• Admission of patients to high-volume centers under the management of a specialized and multidisciplinary team is recommended for optimal outcomes 4.
