Minimally invasive stereotactic puncture and thrombolysis therapy improves long-term outcome after acute intracerebral hemorrhage

Background: Although the NIHSS is a well-validated tool in assessing neurological deficit and predicting long-term outcome in acute cerebral ischemia, its utility in ICH has not been extensively studied. As NIHSS is routinely obtained in cases of stroke prior to imaging, it is often available in ICH patients to potentially assist physicians in triage, prognostication, and risk-adjustment. Methods: We analyzed consecutive patients enrolled in the NIH Field Administration of Stroke Therapy-Magnesium (FAST-MAG) phase 3 trial whose final diagnosis was ICH. Trained study nurses performed the NIHSS in the Emergency Department (ED) shortly after arrival and the modified Rankin Scale (mRS) at 90 days. Primary outcomes were disability or death (mRS 3-6) and mortality. Candidate potential predictor variables, including NIHSS, ICH Score, and GCS, those with threshold of p<0.10 were candidate parameters for backward selection logistic regression to determine independent predictors of disability or death and of mortality. Results: Among the 384 ICH patients, age was mean 65 (±13); female 34%; race white 78%, black 10%, Asian 10%; Hispanic ethnicity 33%; and history of hypertension 78%. The ED NIHSS and GCS was performed a median 148 minutes (IQR 121-180) after last known well. Initial NIHSS was median 16 (IQR 9-16), GCS 15 (IQR 10-15), and ICH Score 1(IQR 0-2). NIHSS correlated with ICH Score (r=0.780) and GCS (r=0.860). At 90 days, median mRS was 4 (IQR 2-6), disability or death (mRS 3-6) was present in 70%, and mortality occurred in 26%. In predicting disability or death at 90 days, c statistics were: NIHSS 0.81, ICH Score 0.81, and GCS 0.72. NIHSS≥14 showed 72% sensitivity and 75% specificity. For mortality by 90 days, c statistics were: NIHSS 0.78, ICH Score 0.80, and GCS 0.73. NIHSS≥19 had 80% sensitivity and 70% specificity. On multivariate analysis age (OR 1.07, 95%CI 1.04-2.0) and NIHSS (OR 1.18, 95%CI 1.13-1.23) were independent predictors of disability and death. Conclusions: The initial NIHSS is a strong predictor of disability and death and good predictor of mortality after intracerebral hemorrhage, performing as well as the ICH Score and better than the GCS. Consideration should be given to routine performance and documentation of the NIHSS in ICH patients.

Abstract INTRODUCTION Preclinical and preliminary clinical data suggests that early minimally invasive intracerebral hemorrhage evacuation may convey a functional outcome benefit. Ongoing clinical trials permit an operative window extending out to 72 h. Here we present long term functional outcome after MIS endoscopic ICH evacuation with a focus on time to evacuation. METHODS Minimally invasive endoscopic ICH evacuation was performed on patients with supratentorial ICH who fit previously published clinical criteria including age = 18, National Institutes of Health Stroke Scale (NIHSS) = 6, hematoma volume = 15, and baseline modified Rankin Score (mRS) = 3 with a CTA negative for vascular malformation. Retrospective review was performed on patients who were treated in a single health system from December 2015 to August 2018. Demographic, clinical and radiographic previously demonstrated to impact ICH outcome were included in a multivariate logistic regression to identify factors predicting poor outcome (modified Rankin scale (mRS) 4-6) at 6 mo. RESULTS A total of 97 patients underwent minimally invasive endoscopic ICH evacuation. In a multivariate analysis, factors that predicted poor outcome included age (OR 1.81 (CI 1.15-3.08) P = .016), deep location (OR 11.1 (2.41-67.8) P = .004), presence of intraventricular hemorrhage (OR 5.81 (1.765-22.39) P = .006) and increased time to evacuation measured in hours (OR 1.048 (CI 1.017-1.084) P = .004). CONCLUSION Time to evacuation significantly impacts long term outcome in minimally invasive endoscopic ICH evacuation. Every minute counts.

Introduction: Preclinical data have demonstrated a time-dependent benefit to early intracerebral hemorrhage (ICH) evacuation while clinical data have been less clear. Here we present long term functional outcome after minimally invasive endoscopic intracerebral hemorrhage evacuation with a focus on time to evacuation (TTE). Methods: Minimally invasive endoscopic ICH evacuation was performed on patients with supratentorial ICH who fit prespecified clinical inclusion and exclusion criteria agreed upon by a multidisciplinary group of physicians in the health care system. Retrospective analysis of prospectively collected data was performed on patients who were treated from December 2015 to October 2018. Demographic, clinical, and radiographic factors previously demonstrated to impact functional outcome in ICH were included in a multivariate logistic regression to identify factors predicting favorable outcome (modified Rankin Scale 0-3) at 6 months post-hemorrhage. Results: Ninety patients underwent MIS endoscopic ICH evacuation within 72 hours of ictus. In a multivariate analysis, factors that were identified to predict a positive outcome included age (per decade, OR 0.48, 95% CI 0.28-0.82) presence of intraventricular hemorrhage (OR 0.23, 95% CI 0.07-0.79), cortical location (OR 19.89, 95% CI 3.37-117.39), early evacuation (per hour, OR 0.95, 95% CI 0.92-0.99). Patients who underwent evacuation within 24 hours were 5 times more likely to achieve a favorable outcome (OR 5.29, 95% CI 1.52-18.41). Early evacuation did not correlate with increased risk of rebleeding. Conclusion: Time to evacuation significantly impacts long term outcome in minimally invasive endoscopic ICH evacuation. Every one hour evacuation is delayed results in a 5% reduction in the odds of achieving a favorable long-term outcome.

Baseline Characteristics

Background and Purpose: Hemispheric location might influence outcome after intracerebral hemorrhage (ICH). INTERACT suggested higher short-term mortality in right hemispheric ICH, yet statistical imbalances were not addressed. This study aimed at determining the differences in long-term functional outcome in patients with right- vs. left-sided ICH with a priori-defined sub-analysis of lobar vs. deep bleedings. Methods: Data from a prospective hospital registry were analyzed including patients with ICH admitted between January 2006 and August 2014. Data were retrieved from institutional databases. Outcome was assessed using the modified Rankin Scale (mRS) score. Outcome measures (long-term mortality and functional outcome at 12 months) were correlated with ICH location and hemisphere, and the imbalances of baseline characteristics were addressed by propensity score matching. Results: A total of 831 patients with supratentorial ICH (429 left and 402 right) were analyzed. Regarding clinical baseline characteristics in the unadjusted overall cohort, there were differences in disfavor of right-sided ICH (antiplatelets: 25.2% in left ICH vs. 34.3% in right ICH; p < 0.01; previous ischemic stroke: 14.7% in left ICH vs. 19.7% in right ICH; p = 0.057; and presence/extent of intraventricular hemorrhage: 45.0% in left ICH vs. 53.0% in right ICH; p = 0.021; Graeb-score: 0 [0-4] in left ICH vs. 1 [0-5] in right ICH; p = 0.017). While there were no differences in mortality and in the proportion of patients with favorable vs. unfavorable outcome (mRS 0-3: 142/375 [37.9%] in left ICH vs. 117/362 [32.3%] in right ICH; p = 0.115), patients with left-sided ICH showed excellent outcome more frequently (mRS 0-1: 64/375 [17.1%] in left ICH vs. 43/362 [11.9%] in right ICH; p = 0.046) in the unadjusted analysis. After adjusting for confounding variables, a well-balanced group of patients (n = 360/hemisphere) was compared showing no differences in long-term functional outcome (mRS 0-3: 36.4% in left ICH vs. 33.9% in right ICH; p = 0.51). Sub-analyses of patients with deep vs. lobar ICH revealed also no differences in outcome measures (mRS 0-3: 53/151 [35.1%] in left deep ICH vs. 53/165 [32.1%] in right deep ICH; p = 0.58). Conclusion: Previously described differences in clinical end points among patients with left- vs. right-hemispheric ICH may be driven by different baseline characteristics rather than by functional deficits emerging from different hemispheric functions affected. After statistical corrections for confounding variables, there was no impact of hemispheric location on functional outcome after ICH.

Spine surgery as we know it has changed dramatically over the past 2 decades. More patients are undergoing minimally invasive procedures. Surgeons are becoming more comfortable with these procedures, and changes in technology have led to several new approaches and products to make surgery safer for patients and improve patient outcomes. As more patients undergo minimally invasive spine surgery, more long-term outcome and complications data have been collected. The authors describe the common complications associated with these minimally invasive surgical procedures and delineate management options for the spine surgeon.
