Decompressive Hemicraniectomy

Ischemic stroke and intracranial hemorrhage are among the most devastating and debilitating injuries in medicine. Initial management principles for acute ischemic stroke rely on prompt revascularization before the brain parenchymal is infarcted. Large hemispheric infarctions and malignant cerebral edema occur uncommonly in a subset of patients with acute ischemic stroke and are associated with high morbidity and mortality rates. The indications for decompressive hemicraniectomy for malignant cerebral edema are reviewed. Medical management of intraparenchymal hematomas and aneurysmal subarachnoid hemorrhage in the intensive care setting is emphasized. Important clinical sequelae of subarachnoid hemorrhage such as rebleeding, cerebral vasospasm, and cerebral salt wasting are reviewed.   This review contains 5 figures, 4 tables and 52 references Key Words:  acute ischemic stroke, cerebral aneurysm, cerebral vasospasm, decompressive hemicraniectomy, intracerebral hemorrhage, large hemispheric infarctions, subarachnoid hemorrhage, malignant cerebral edema

Patients At Risk

Background and Purpose: Aneurysmal subarachnoid hemorrhage is a devastating disease leaving surviving patients often severely disabled. Delayed cerebral ischemia (DCI) has been identified as one of the main contributors to poor clinical outcome after subarachnoid hemorrhage. The objective of this review is to summarize existing clinical evidence assessing the diagnostic value of invasive neuromonitoring (INM) in detecting DCI and provide an update of evidence since the 2014 consensus statement on multimodality monitoring in neurocritical care. Methods: Three invasive monitoring techniques were targeted in the data collection process: brain tissue oxygen tension (p ti O 2 ), cerebral microdialysis, and electrocorticography. Prospective and retrospective studies as well as case series (≥10 patients) were included as long as monitoring was used to detect DCI or guide DCI treatment. Results: Forty-seven studies reporting INM in the context of DCI were included (p ti O 2 : N=21; cerebral microdialysis: N=22; electrocorticography: N=4). Changes in brain oxygen tension are associated with angiographic vasospasm or reduction in regional cerebral blood flow. Metabolic monitoring with trend analysis of the lactate to pyruvate ratio using cerebral microdialysis, identifies patients at risk for DCI. Clusters of cortical spreading depolarizations are associated with clinical neurological worsening and cerebral infarction in selected patients receiving electrocorticography monitoring. Conclusions: Data supports the use of INM for the detection of DCI in selected patients. Generalizability to all subarachnoid hemorrhage patients is limited by design bias of available studies and lack of randomized trials. Continuous data recording with trend analysis and the combination of INM modalities can provide tailored treatment support in patients at high risk for DCI. Future trials should test interventions triggered by INM in relation to cerebral infarctions.

Introduction Hypothermia has been increasingly used for cerebral resuscitation in comatose survivors of cardiac arrest. A large number of studies have been undertaken in patients with traumatic brain injury to asses the efficacy of hypothermia for reduction of intracranial hypertension. Hypothermia has also been shown to reduce mortality and increase functional outcome if used for longer duration in patients with severe traumatic brain injury. Due to the risk of rebound cerebral edema during re-warming, medical complications and other factors, hypothermia has not been widely utilized for other neurologic catastrophes. To determine the safety and feasibility of hypothermia to treat intracranial hypertension in patients with aneurysmal subarachnoid hemorrhage (SAH), we performed this study. Methods Retrospective analysis was performed on 11 consecutive patients with poor grade (Hunt and Hess IV and V) SAH who had high intracranial pressure that was either non responsive or poorly responsive to conventional methods (head of bed at 30 degrees, sedation, CSF drainage and osmotherapy). All patients had intracranial pressure (ICP) monitoring via an external ventriculostomy drain (EVD) catheter. Hypothermia was induced non-invasively via surface cooling pads (Artic Sun Temperature Management System). Intravenous sedation and paralysis was used via intravenous infusion to control shivering. Hypothermia (target temperature of 32 to 34 degree C) was maintained until ICP normalized. Results Duration of hypothermia ranged from 79 hours to 190 hours. One patient required re-induction due to rebound increase in ICP during re-warming. Modified rankin scale was recorded at 3 month after the ictus. Eight patients (72%) survived with good recovery, one patient (9%) survived with severe disability and two patients (18%) died. The most common side effect was electrolyte imbalance seen in seven patients (63%), thrombocytopenia in three patients (27%), and pneumonia in four patients(36%). All complications were successfully treated and major consequences of complications (bleeding diathesis, septic shock syndrome and death) were not observed in any of these patients. Two patients had decompressive hemicraniectomy prior to hypothermia induction. Out of nine patients who did not undergo hemi-craniectomy, two died and seven did not require surgical intervention after induction of hypothermia. Conclusions Mild hypothermia induction for 72 hours or more for the treatment of intracranial hypertension refractory to other conventional methods in patients with SAH appears safe and feasible. Hypothermia may potentially be an earlier treatment option than currently recommended. This study serves as a template for future efficacy trials.

Abstract OBJECTIVE To evaluate the feasibility and safety of mild hypothermia treatment in patients with aneurysmal subarachnoid hemorrhage (SAH) who are experiencing intracranial hypertension and/or cerebral vasospasm (CVS). METHODS Of 441 consecutive patients with SAH, 100 developed elevated intracranial pressure and/or symptomatic CVS refractory to conventional treatment. Hypothermia (33–34°C) was induced and maintained until intracranial pressure normalized, CVS resolved, or severe side effects occurred. RESULTS Thirteen patients were treated with hypothermia alone, and 87 were treated with hypothermia in combination with barbiturate coma. Sixty-six patients experienced poor-grade SAH (Hunt and Hess Grades IV and V) and 92 had Fisher Grade 3 and 4 bleedings. The mean duration of hypothermia was 169 ± 104 hours, with a maximum of 16.4 days. The outcome after 1 year was evaluated in 90 of 100 patients. Thirty-two patients (35.6%) survived with good functional outcome (Glasgow Outcome Scale [GOS] score, 4 and 5), 14 (15.5%) were severely disabled (GOS score, 3), 1 (1.1%) was in a vegetative state (GOS score, 2), and 43 (47.8%) died (GOS score, 1). The most frequent side effects were electrolyte disorders (77%), pneumonia (52%), thrombocytopenia (47%), and septic shock syndrome (40%). Of 93 patients with severe side effects, 6 (6.5%) died as a result of respiratory or multi-organ failure. CONCLUSION Prolonged systemic hypothermia may be considered as a last-resort option for a carefully selected group of SAH patients with intracranial hypertension or CVS resistant to conventional treatment. However, complications associated with hypothermia require elaborate protocols in general intensive care unit management.

Introduction: Cerebral vasospasm (CVS) is a complication of aneurysmal subarachnoid hemorrhage (aSAH). Intraventricular milrinone (IVtM) and intravenous milrinone (IVM) have been studied for treatment of CVS. We aimed to determine the effect of milrinone therapy on clinical and transcranial Doppler (TCD) measures of CVS. Methods: We performed a retrospective analysis of patients with aSAH treated with IVtM at a single tertiary center between 2016 and 2018. Patients were treated with IVtM if they had symptomatic CVS or TCD suggestive of critical CVS that persisted despite blood pressure augmentation or endovascular therapies. Nimodipine was given as standard of care. A subset of patients were also treated with IVM, which was dosed in a standard fashion based on Montreal Neurological Institute protocol. We collected demographic data, TCD mean flow velocity and pulsatility index, angiographic data, as well as utilization and frequency of IVtM and IVM. Results: Twenty-eight patients in our cohort had modified Fisher grade 4 (57%) or grade 3 (25%) and median Hunt-Hess score of 3 (IQR 2, 4). Twenty-one of 28 patients were treated with IVtM+IVM. Seven (25%) who received IVtM alone had no significant improvement in TCD velocities or reduction in symptomatic CVS (p=0.611). Patients received between 1 and 30 doses of IVtM. There was no significant improvement with time or with number of IVtM doses IVtM. There was also no significant improvement in TCD velocities of CVS patients nor reduction in symptomatic CVS with IVtM+IVM (p=0.69). The number of IVtM doses correlated with an increased discharge mRS (p=0.05). There were no direct complications due to IVtM or IVM. Conclusion: Neither IVtM+IVM nor IVtM alone appear to be effective treatment of CVS in aSAH. Our data represent one of the first case series reporting IVtM and IVtM+IVM utilization for the treatment of CVS.
