Early decompressive craniectomy for malignant cerebral infarction: Meta-analysis and clinical decision algorithm.

ABSTRACT: Decompressive craniectomy (DC) is an aggressive life-saving surgical intervention for patients with malignant cerebral infarction (MCI). However, DC remains inconsistently and infrequently utilized, primarily due to enduring concern that increased survival occurs only at the cost of poor functional outcome. Our aim was to clarify the role of DC performed within 48 hours (early DC) for patients with MCI, including patients aged >60 years.We performed a meta-analysis of all available randomized controlled trials comparing early DC to best medical care for MCI. Studies were identified through literature searches of electronic databases including PubMed, EMBASE, and Scopus. We employed a Mantel-Haenszel fixed effects model to assess treatment effect on dichotomized modified Rankin Scale (mRS) outcomes at 12 months.A total of 289 patients from 6 randomized controlled trials comparing early DC to best medical care were included. Early DC resulted in an increased rate of excellent outcomes, defined as mRS ?2 (relative risk [RR] 2.81, 95% confidence interval [CI] 1.01-7.82, p = 0.047), and favorable outcomes, defined as mRS ?3 (RR 2.06, 95% CI 1.25-3.40, p = 0.005). Early DC also increased the rate of survival with unfavorable outcomes, defined as mRS 4-5 (RR 3.03, 95% CI 1.98-4.65, p < 0.001).Early DC increases the rate of excellent outcomes, i.e., functional independence, in addition to favorable and unfavorable outcomes; however, these findings must be interpreted within the context of patients' goals of care. We have developed a clinical decision algorithm that incorporates goals of care, which may guide consideration of early DC for MCI in clinical practice.

Project description:BackgroundMalignant middle cerebral artery infarction is a potentially life-threatening disease. Decompressive hemicraniectomy constitutes an evidence-based treatment practice, especially in patients under 60 years of age; however, recommendations with respect to postoperative management and particularly duration of postoperative sedation lack standardization.ObjectiveThis survey study aimed to analyze the current situation of patients with malignant middle cerebral artery infarction following hemicraniectomy in the neurointensive care setting.Material and methodsFrom 20 September 2021 to 31 October 2021, 43 members of the initiative of German neurointensive trial engagement (IGNITE) network were invited to participate in a standardized anonymous online survey. Descriptive data analysis was performed.ResultsOut of 43 centers 29 (67.4%) participated in the survey, including 24 university hospitals. Of the hospitals 21 have their own neurological intensive care unit. While 23.1% favored a standardized approach regarding postoperative sedation, the majority utilized individual criteria (e.g., intracranial pressure increase, weaning parameters, complications) to assess the need and duration. The timing of targeted extubation varied widely between hospitals (≤ 24 h 19.2%, ≤ 3 days in 30.8%, ≤ 5 days in 19.2%, > 5 days in 15.4%). Early tracheotomy (≤ 7 days) is performed in 19.2% and 80.8% of the centers aim for tracheotomy within 14 days. Hyperosmolar treatment is used on a regular basis in 53.9% and 22 centers (84.6%) agreed to participate in a clinical trial addressing the duration of postoperative sedation and ventilation.ConclusionThe results of this nationwide survey among neurointensive care units in Germany reflect a remarkable heterogeneity in the treatment practices of patients with malignant middle cerebral artery infarction undergoing hemicraniectomy, especially with respect to the duration of postoperative sedation and ventilation. A randomized trial in this matter seems warranted.

Project description:Introduction Decompressive hemicraniectomy (DCE) is routinely performed for intracranial pressure control after malignant middle cerebral artery (MCA) infarction. Decompressed patients are at risk of traumatic brain injury and the syndrome of the trephined until cranioplasty. Cranioplasty after DCE is itself associated with high complication rates. Single-stage surgical strategies may eliminate the need for follow-up surgery while allowing for safe brain expansion and protection from environmental factors. Research question Assess the volume needed for safe expansion of the brain to enable single-stage surgery. Materials and methods We performed a retrospective radiological and volumetric analysis of all patients that had DCE in our clinic between January 2009 and December 2018 and met inclusion criteria. We investigated prognostic parameters in perioperative imaging and assessed clinical outcome. Results Of 86 patients with DCE, 44 fulfilled the inclusion criteria. Median brain swelling was 75.35 mL (8.7–151.2 mL). Median bone flap volume was 113.3 mL (73.34–146.1 mL). Median brain swelling was 1.62 mm below the previous outer rim of the skull (5.3 mm to –2.19 mm). In 79.6% of the patients, the volume of removed bone alone was equivalent to or larger than the additional intracranial volume needed for brain swelling. Discussion and conclusion The space provided by removal of the bone alone was sufficient to match the expansion of the injured brain after malignant MCA infarction in the vast majority of our patients A subgaleal space-expanding flap with a minimal offset can provide protection from trauma and atmospheric pressure without compromising brain expansion. Highlights • Volume augmentation of the swollen brain is smaller than the volume of removed bone in 79.6% of cases.• An additional Volume of about 50 mL would have provided adequate space for the swollen brain in all cases.• Maximum modeled brain swelling outside of the previous skull limit is 2.19 mm.
