The Impact

Background and Objective: Intraventricular hemorrhage (IVH) is a verified independent prognostic parameter in patients with intracerebral hemorrhage (ICH). However, the impact of the extent of IVH on clinical outcomes is unestablished. Methods: We analyzed 1,112 consecutive primary ICH patients of the UKER-ICH cohort (NCT03183167) and hypothesized that there is no difference in outcome between patients without IVH and patients with minor IVH not leading to obstructive hydrocephalus. Propensity score matching and multivariable analyses were performed to account for imbalances in baseline characteristics. Primary outcome was defined as functional outcome 3 months after ICH ­assessed using the modified Rankin Scale (mRS) dichotomized into favorable (mRS = 0–3) and unfavorable outcome (mRS = 4–6). Secondary outcomes included mortality at 3  months and a Graeb score-based threshold analysis for association of the extent of IVH with unfavorable clinical outcome. Results: Among the 461 out of 1,112 (41.5%) ICH patients with IVH, 191 out of 461 (41.4%) showed IVH without obstructive hydrocephalus and no requirement of external ventricular drain (EVD) placement. After adjusting for baseline imbalances we found no difference in functional outcome at 3 months between patients without IVH (No-IVH) and patients with IVH not requiring EVD (IVH-w/o-EVD): mRS 0–3: No-IVH 64/161 (39.8%) vs. IVH-w/o-EVD 53/170 (31.2%); p = 0.103. However, there was a trend toward a higher mortality in IVH-w/o-EVD patients (mRS 6: No IVH 40/161 [24.8%] vs. IVH-w/o-EVD 57/170 [33.5%]; p = 0.083). Multivariable analysis revealed that a Graeb score >2 was independently associated with unfavorable outcome (mRS 4–6: OR 3.16 [1.54–6.48]; p = 0.002), and higher mortality (mRS 6: OR 2.57 [1.40–4.74]; p = 0.002) in IVH patients. Conclusions: Small amounts of intraventricular blood (Graeb score ≤2) not leading to obstructive hydrocephalus are not associated with unfavorable outcome or death after ICH. Thus, IVH per se should not be considered a binary variable in outcome prediction for ICH patients.

The Impact

Background: Troponin I is a widely used and reliable marker of myocardial damage and its levels are routinely measured in acute stroke care. So far, the influence of troponin I elevations during hospital stay on functional outcome in patients with atraumatic intracerebral hemorrhage (ICH) is unknown. Methods: Observational single-center study including conservatively treated ICH patients over a 9-year period. Patients were categorized according to peak troponin I level during hospital stay (≤0.040, 0.041–0.500, > 0.500 ng/mL) and compared regarding baseline and hematoma characteristics. Multivariable analyses were performed to investigate independent associations of troponin levels during hospital stay with functional outcome – assessed using the modified Rankin Scale (mRS; favorable 0–3/unfavorable 4–6) – and mortality after 3 and 12 months. To account for possible confounding propensity score (PS)-matching (1: 1; caliper 0.1) was performed accounting for imbalances in baseline characteristics to investigate the impact of troponin I values on outcome. Results: Troponin elevations (> 0.040 ng/mL) during hospital stay were observed in 308 out of 745 (41.3%) patients and associated with poorer status on admission (Glasgow Coma Scale/National Institute of Health Stroke Scale). Multivariable analysis revealed troponin I levels during hospital stay to be independently associated with unfavorable outcome after 12 months (risk ratio [95% CI]: 1.030 [1.009–1.051] per increment of 1.0 ng/mL; p = 0.005), but not with mortality. After PS-matching, patients with troponin I elevation (≥0.040 ng/mL) versus those without had a significant higher rate of ­unfavorable outcome after 3 and 12 months (mRS 4–6 at 3 months: < 0.04 ng/mL: 159/265 [60.0%] versus ≥0.04 ng/mL: 199/266 [74.8%]; p < 0.001; at 12 months: < 0.04 ng/mL: 141/248 [56.9%] versus ≥0.04 ng/mL: 179/251 [71.3%]; p = 0.001). Conclusions: Troponin I elevations during hospital stay occur frequently in ICH patients and are independently associated with functional outcome after 3 and 12 months but not with mortality.

Introduction: Intraventricular hemorrhage (IVH) occurs in about 40% of patients with intracerebral hemorrhage (ICH) and is associated with higher mortality and worse outcomes than ICH patients without IVH. Infections are common in ICH patients but data in IVH patients are limited. Methods: Prospective analysis of adjudicated adverse event infection reporting during first 180 days in 500 patients enrolled in the CLEAR III trial, a multicenter, double-blind, randomized study comparing external ventricular drain (EVD) + intraventricular recombinant tissue plasminogen activator (rtPA) vs. EVD + placebo for treatment of obstructive IVH and intracerebral hemorrhage (ICH) volume <30cc. Primary outcome measures were 90-day and 180-day mortality. Secondary outcome measures were hospital length of stay (LOS). We constructed binary logistic and linear regression models for multivariable analysis. Results: Infection was reported in 269 patients (53.8%). Pneumonia was the most common infection (33%), followed by UTI (16%), and bacterial ventriculitis (4.4%). Overall 180-day mortality was 20%. Patients with infection were more likely to have older age (p=0.012), lower admission GCS (p=0.007), higher ICH volume (8.8 vs 6.7ml, p=0.001), and higher ICH+IVH volume (37.7 vs 31.7 ml, p=0.002). In the regression model, IVH volume was associated with higher odds of 90-day or 180-day mortality, but presence of any infection was not a significant predictor of mortality. Infection was however associated with longer length of stay (26 vs 22 days, p<0.001). Subgroup analysis of individual infections, showed only bacterial ventriculitis to be associated with 90-day (OR: 3.84, CI: 1.36-10.82), and 180-day mortality (OR: 2.9, CI: 1.05-8.06), while pneumonia and UTI were not. Conclusion: Patients with IVH have a high incidence of infections, which is associated with longer hospitalization but does not appear to influence mortality. Of the infections, bacterial ventriculitis is a significant predictor of mortality in our 7-factor model. IVH volume did not predict infections but predicted mortality.These results form a basis for future correlation of infectious complications with treatment rendered (thrombolysis versus placebo), with upcoming unblinding of the trial.

Object Intraventricular hemorrhage (IVH) associated with intracerebral hemorrhage (ICH) is an independent predictor of poor outcome. Clinical methods for evaluating IVH, however, are not well established. This study sought to determine the best IVH grading scale by evaluating the predictive accuracies of IVH, Graeb, and LeRoux scores in an independent cohort of ICH patients with IVH. Subacute IVH dynamics as well as the impact of external ventricular drain (EVD) placement on IVH and outcome were also investigated. Methods A consecutive cohort of 142 primary ICH patients with IVH was admitted to Columbia University Medical Center between February 2009 and February 2011. Baseline demographics, clinical presentation, and hospital course were prospectively recorded. Admission CT scans performed within 24 hours of onset were reviewed for ICH location, hematoma volume, and presence of IVH. Intraventricular hemorrhage was categorized according to IVH, Graeb, and LeRoux scores. For each patient, the last scan performed within 6 days of ictus was similarly evaluated. Outcomes at discharge were assessed using the modified Rankin Scale (mRS). Receiver operating characteristic analysis was used to determine the predictive accuracies of the grading scales for poor outcome (mRS score ≥ 3). Results Seventy-three primary ICH patients (51%) had IVH. Median admission IVH, Graeb, and LeRoux scores were 13, 6, and 8, respectively. Median IVH, Graeb and LeRoux scores decreased to 9 (p = 0.005), 4 (p = 0.002), and 4 (p = 0.003), respectively, within 6 days of ictus. Poor outcome was noted in 55 patients (75%). Areas under the receiver operating characteristic curve were similar among the IVH, Graeb, and LeRoux scores (0.745, 0.743, and 0.744, respectively) and within 6 days postictus (0.765, 0.722, 0.723, respectively). Moreover, the IVH, Graeb, and LeRoux scores had similar maximum Youden Indices both at admission (0.515 vs 0.477 vs 0.440, respectively) and within 6 days postictus (0.515 vs 0.339 vs 0.365, respectively). Patients who received EVDs had higher mean IVH volumes (23 ± 26 ml vs 9 ± 11 ml, p = 0.003) and increased incidence of Glasgow Coma Scale scores < 8 (67% vs 38%, p = 0.015) and hydrocephalus (82% vs 50%, p = 0.004) at admission but had similar outcome as those who did not receive an EVD. Conclusions The IVH, Graeb, and LeRoux scores predict outcome well with similarly good accuracy in ICH patients with IVH when assessed at admission and within 6 days after hemorrhage. Therefore, any of one of the scores would be equally useful for assessing IVH severity and risk-stratifying ICH patients with regard to outcome. These results suggest that EVD placement may be beneficial for patients with severe IVH, who have particularly poor prognosis at admission, but a randomized clinical trial is needed to conclusively demonstrate its therapeutic value.

Vte Prophylaxis

Introduction: Intraventricular hemorrhage (IVH) occurs in about 40% of patients with intracerebral hemorrhage (ICH) and is associated with higher mortality and worse outcomes than ICH patients without IVH. Venous thromboembolism (VTE) is common in ICH patients but data in IVH patients are limited. Methods: Prospective analysis of adjudicated adverse event reporting of VTE (deep venous thrombosis (DVT) and pulmonary embolism (PE)) during first 180 days in 500 patients enrolled in the CLEAR III trial, a multicenter, double-blind, randomized study comparing external ventricular drain (EVD) + intraventricular recombinant tissue plasminogen activator (rtPA) vs EVD + placebo for treatment of obstructive IVH and intracerebral hemorrhage (ICH) volume <30cc. Outcome measures were 90-day and 180-day mortality, ICU and hospital length of stay (LOS), catheter tract hemorrhage as well as predictors of VTE. Results: VTE was reported in 63 patients (13%); 46 (9%), 11 (2%) and 6 (1%) patients had DVT, PE or both, respectively. VTE occurred between 4 and 209 days from ICH onset. VTE pharmacologic prophylaxis was initiated in 404 (81%) patients, at median of 4 days [range:1-48] from ICH onset. Unfractionated and low molecular weight heparin were used in 71% and 29% patients, respectively. These patients had similar rates of VTE but showed a trend towards higher catheter tract hemorrhages (25 vs 15%, p=0.056) as compared to those who did not receive VTE prophylaxis. Patients who developed VTE had similar 90-d and 180-d mortality and ICU LOS but had prolonged hospital LOS (p=0.012) as compared to those who did not develop VTE. On multivariable analysis, ICH volume was a significant predictor of development of VTE (OR 1.04, 95% CI: 1.01-1.07, p=0.024). Conclusions: The association of IVH with VTE is important but complex, in spite of consideration of early VTE prophylaxis. There was trend towards higher catheter tract hemorrhages in patients receiving VTE prophylaxis. ICH volume was a significant predictor of VTE development. However, mortality and ICU LOS were not affected by VTE development. These results form a basis for future correlation of VTE complications with treatment rendered (thrombolysis versus placebo), with upcoming unblinding of the trial.

AbstractData on the impact of kidney dysfunction on outcome in patients with stroke due to large vessel occlusion are scarce. The few available studies are limited by only considering single kidney parameters measured at one time point. We thus investigated the influence of both chronic kidney disease (CKD) and acute kidney injury (AKI) on outcome after mechanical thrombectomy. We included consecutive patients with anterior circulation large vessel occlusion stroke receiving mechanical thrombectomy at our center over an 8-year period. We extracted clinical data from a prospective registry and investigated kidney serum parameters at admission, the following day and throughout hospital stay. CKD and AKI were defined according to established nephrological criteria. Unfavorable outcome was defined as scores of 3–6 on the modified Rankin Scale 3 months post-stroke. Among 465 patients, 31.8% had an impaired estimated glomerular filtration rate (eGFR) at admission (< 60 ml/min/1.73 m2). Impaired admission eGFR was related to unfavorable outcome in univariable analysis (p = 0.003), but not after multivariable adjustment (p = 0.96). Patients frequently met AKI criteria at admission (24.5%), which was associated with unfavorable outcome in a multivariable model (OR 3.03, 95% CI 1.73–5.30, p < 0.001). Moreover, patients who developed AKI during hospital stay also had a worse outcome (p = 0.002 in multivariable analysis). While CKD was not associated with 3-month outcome, we identified AKI either at admission or throughout the hospital stay as an independent predictor of unfavorable prognosis in this study cohort. This finding warrants further investigation of kidney–brain crosstalk in the setting of acute stroke.

SummaryPatients exhibiting high on-clopidogrel platelet reactivity (HPR) are at an increased risk of atherothrombotic events following percutaneous coronary interventions (PCI). The use of concomitant medication which is metabolised by the hepatic cytochrome P450 system, such as phenprocoumon, is associated with HPR. We assessed the level of platelet reactivity on clopidogrel in patients who received concomitant treatment with acenocoumarol (another coumarin derivative). Patients scheduled for PCI were included in a prospective, single centre, observational registry. Patients who were adequately pre-treated with clopidogrel were eligible for this analysis, which included 1,582 patients, of whom 104 patients (6.6 %) received concomitant acenocoumarol treatment. Platelet reactivity, as measured with the VerifyNow P2Y12 assay and expressed in P2Y12 Reaction Units (PRU), was significantly higher in patients on concomitant acenocoumarol treatment (mean PRU 229 ± 88 vs 187 ± 95; p< 0.001). In patients with concomitant acenocoumarol use, the proportion of patients with HPR was higher, defined as PRU > 208 (57.7 % vs 41.1 %; p=0.001) and PRU236 (49.0 % vs 31.4 %; p< 0.001). In multivariable analysis, concomitant acenocoumarol use was independently associated with a higher PRU and the occurrence of HPR defined as PRU236 (OR 2.00, [1.07–3.79]), but not with HPR defined as PRU > 208 (OR 1.37, [0.74–2.54]). PRU also was significantly increased after 1:1 propensity matching (+28.2; p< 0.001). As this was an observational study, confounding by indication cannot be excluded, although multivariable analyses and propensity matching were performed. The impact of the findings from this hypothesis-generating study on clinical outcome requires further investigation.

Background: Intraventricular haemorrhage (IVH) patients with acute obstructive hydrocephalus (AOH) who require external ventricular drainage (EVD) are at high risk for poor outcomes. Intraventricular fibrinolysis (IVF) with low-dose recombinant tissue plasminogen activator (rtPA) can be used to improve patient outcomes. Here, we evaluated the impact of IVF on the risk of death and the functional outcomes in IVH patients with AOH. Methods: This prospective cohort study included IVH patients with hypertensive intracranial haemorrhage complicated by AOH who required EVD. We evaluated the risk of death and the functional outcomes at 1 and 3 months, with a specific focus on the impact of combined EVD with IVF by low-dose rtPA. Results: Between November 30, 2011 and December 30, 2014, 80 patients were included. Forty-five patients were treated with EVD alone (EVD group) and 35 received IVF (EVD+IVF group). The 30- and 90-day mortality rates were lower in the EVD+IVF group than in the EVD group (42.2 vs. 11.4%, p = 0.003, and 62.2 vs. 20%, p < 0.001, respectively). The Graeb scores were significantly lower in the EVD+IVF group than in the EVD group (p ≤ 0.001) during the first 3 days and on day 7 after assignment. The 30-day good functional outcome (modified Rankin Scale [mRS] score 0–3) was also higher in the EVD+IVF group than in the EVD group (6.7 vs. 28.6%, p = 0.008). However, the 90-day good functional outcome (mRS score 0–3) did not significantly increase in the EVD+IVF group (30.8% in the EVD group vs. 51.6% in the EVD+IVF group, p = 0.112). Conclusions: In our prospective observational study, EVD+IVF was associated with a lower risk of death in IVH patients. EVD+IVF improved the chance of having a good functional outcome at 1 month; however, this result was no longer observed at 3 months.

AbstractSpontaneous intracerebral hemorrhage (ICH) is the most common cause of intraventricular hemorrhage (IVH) in adults. Complicating approximately 40% of ICH cases, IVH adds to the morbidity and mortality of this often fatal form of stroke. It is also a severity factor that complicates subarachnoid hemorrhage and traumatic brain injury, along with other less common causes of intracranial bleeding. Medical and surgical interventions to date have focused on limiting ICH and IVH expansion, controlling intracranial pressure, and relieving obstructive hydrocephalus. The placement of an external ventricular drain (EVD) can achieve the latter two goals but has not demonstrated improvement in clinical outcomes beyond mortality reduction. More recently, intraventricular fibrinolysis, utilizing the EVD, has gained interest as a safe and potentially effective method to maintain catheter patency and facilitate hematoma removal. A recent phase III clinical trial evaluating the efficacy of intraventricular alteplase versus intraventricular saline showed a mortality benefit, but failed to meet the primary endpoint of significant functional improvement. However, planned subgroup analysis focusing on patients with IVH volume > 20 mL, and those with IVH removal > 85% suggest that significant functional benefits may be attainable with this therapy. The practice of intraventricular fibrinolysis for spontaneous IVH is not the standard of care; however, based on 20 years of experience, it meets thresholds as a safe intervention, and in those patients with a high burden of intraventricular blood, aggressive clearance may lead to improved quality of life in survivors of this morbid syndrome.

Objectives Colorectal care bundles for surgical site infections (CRCB-SSIs) have been shown to reduce SSIs following elective colorectal surgery (CRS). There are limited data evaluating the effect of CRCB-SSI at Academic Disproportionate Share Hospitals (ADSH) with significant rates of urgent and emergent cases. Methods A CRCB-SSI was implemented in April 2016. We reviewed medical records of all patients undergoing colon resections between August 2015 and December 2017. Patients were divided into preimplementation and postimplementation groups. The primary endpoint was the SSI rate, and the secondary endpoint included types of SSI (superficial, deep, organ space). Univariable and multivariable analyses were performed. A subset analysis was performed in elective cases. Results We analyzed a total of 417 patients. Of these, 116 (28%) and 301 (72%) patients were in the preimplementation and postimplementation groups, respectively. The rate of SSI decreased from 30.1% to 15.9% in the postimplementation group ( P = .0012); however, it was not statistically significant after adjusting for baseline differences (relative risk [RR] 0.65; 95% CI 0.41-1.02). The elective subset included 219 patients. The rate of SSI in this cohort decreased from 25% to 10.5% in the postimplementation group ( P = .0012) and remained significant following multivariable analysis (RR 0.41, 95% CI 0.19- 0.88). There were no differences in the subtypes of SSI. Discussion While the CRCB-SSI was effective in decreasing the postoperative SSI rate for elective cases, its effect on the overall patient population was limited. CRCB-SSIs are not enough to bring SSI rates to accepted rates in high-risk patients such as those seen at ADSH.

Abstract OBJECTIVE AND IMPORTANCE Intraventricular hemorrhage (IVH) is known to cause acute obstructive hydrocephalus, refractory elevated intracranial pressures (ICPs), and lowered cerebral perfusion pressures, leading to cortical ischemia. Frequent obstruction of external ventricular drains as a result of thrombus is a recurring theme. We present a case of IVH secondary to periventricular arteriovenous malformation (AVM) that was not visible at admission angiography and was treated by intraventricular infusion of recombinant tissue plasminogen activator before surgical intervention. CLINICAL PRESENTATION An 11-year-old boy presented with acute onset of headache followed by two seizures, loss of consciousness, decerebration, right temporal hematoma, IVH, and acute obstructive hydrocephalus. INTERVENTION A right external ventricular drain was placed but functioned poorly. ICP could not be controlled by conventional methods. Five milligrams of recombinant tissue plasminogen activator was injected into the ventricular system via the external ventricular drain. This was repeated daily for 4 days. This treatment resulted in progressive improvement in ICP and clinical status. Once the clot partially cleared, magnetic resonance imaging and magnetic resonance angiography suggested the presence of a right periventricular arteriovenous malformation, which was confirmed by angiography and subsequently resected. CONCLUSION Recombinant tissue plasminogen activator is effective in resolving IVH causing obstructive hydrocephalus and uncontrollable ICP posing a life-threatening situation, secondary to ruptured arteriovenous malformation, before surgical intervention.
