Utilizing the International Normalized Ratio-Platelet Index for Predicting Hospital Outcomes After Spontaneous Supratentorial Intracerebral Hemorrhage.

OBJECTIVE: Spontaneous intracerebral hemorrhage (ICH) poses a public health issue due to its elevated mortality rates. The International Normalized Ratio-platelet index (INR-Plt index) has recently been recognized as a predictive factor for liver disease progression. The potential of applying the INR-Plt index in forecasting ICH prognosis presents an intriguing subject. This study endeavors to examine the correlation between the INR-Plt index and hospital outcomes in patients with spontaneous supratentorial ICH. METHODS: A retrospective examination of 283 adult ICH patients was undertaken. The INR-Plt index was computed using the formula: [INR/platelet counts (1000/µL)] × 100. The clinical outcomes evaluated consisted of mortality rates and the Modified Rankin Scale (mRS) at discharge. An unfavorable outcome was defined as an mRS score from 4 to 6. RESULTS: The study found a significant correlation between the INR-Plt index and hospital mortality (odds ratio: 4.31, 95% CI: 1.07-17.31, P = 0.04). There was a 43% rise in mortality risk for every 0.1 unit increase in the INR-Plt index. Kaplan-Meier survival curves illustrated a considerably lower survival rate at discharge for patients with an INR-Plt index >0.8 (log-rank test: P = 0.047). Regarding unfavorable outcomes, the INR-Plt index was not a significant factor according to logistic regression analyses. CONCLUSIONS: The INR-Plt index is a predictor of hospital mortality in patients with spontaneous supratentorial ICH. A higher INR-Plt index value is associated with an increased risk of mortality, underlining the potential usefulness of this composite index in guiding clinical decision-making and enabling risk stratification.

Exploring the relationship between admission pulse pressure and clinical features in patients with spontaneous supratentorial intracerebral hemorrhage.

Elevated pulse pressure is commonly observed in cardiovascular diseases and serves as an independent risk factor and predictor of cardiac mortality. However, the role of pulse pressure in patients with spontaneous intracerebral hemorrhage (ICH) remains uncertain. This study aimed to investigate the association between admission pulse pressure and clinical characteristics, including in-hospital outcomes, in ICH patients. We retrospectively analyzed the data of 292 ICH patients, categorizing them into two groups based on admission wide pulse pressure: > 100 mmHg (n = 60) and ≤ 100 mmHg (n = 232). Clinical characteristics and in-hospital outcomes were compared between the groups, and multivariate logistic regression was performed to identify independent factors. Patients with wide pulse pressure were older, had lower Glasgow Coma Scale, larger intraparenchymal hematomas, more pronounced midline shifts, and higher rates of intraventricular hematoma extension and hydrocephalus. These patients also experienced higher frequencies of craniotomy or craniectomy and longer hospital stays. Multivariate logistic regression revealed that pulse pressure > 100 mmHg was significantly associated with increased in-hospital mortality (odds ratio 4.31, 95% confidence interval 1.12-16.62, p = 0.03), but not with a modified Rankin Scale score of 4-6. In conclusion, our investigation demonstrates a significant relationship between admission pulse pressure and severe clinical characteristics in ICH patients. Importantly, a wider pulse pressure is linked to heightened in-hospital mortality. These results underscore the necessity for customized strategies to predict patient outcomes in this population. Further research is essential to explore potential therapeutic interventions targeting pulse pressure to improve clinical outcomes for ICH patients.

Intraventricular Hemorrhage Score as a Robust Predictor for Shunt-Dependent Hydrocephalus After Spontaneous Supratentorial Intracerebral Hemorrhage.

OBJECTIVE: Spontaneous intracerebral hemorrhage (ICH) is a common stroke subtype, and patients often develop intraventricular hemorrhage (IVH) and hydrocephalus (H). It is essential to promptly recognize factors that can predict the need for permanent cerebrospinal fluid shunt. This study aims to assess the potential of the IVH score as a predictor for shunt-dependent H in ICH patients. METHODS: We retrospectively reviewed data from 296 patients with spontaneous supratentorial ICH. Clinical and radiographic data were analyzed. IVH scores were calculated based on initial brain computed tomography scans. A multivariable logistic regression analysis was performed to identify independent predictors of shunt-dependent H, and a receiver operating characteristic curve was generated for the IVH score. RESULTS: Among the 296 ICH patients, 25 (8.4%) required permanent cerebrospinal fluid shunt placement. The IVH score was identified as the sole significant independent predictor of shunt-dependent H (P < 0.01), with an odds ratio of 1.13 and a 95% confidence interval between 1.04 and 1.22. With each unit increase in the IVH score, the likelihood of shunt dependence rises by 13%. The area under the curve for the IVH score as a predictor of shunt-dependent H was 0.818. With an IVH score threshold of 6.5, the sensitivity was 80.0%, and the specificity was 26.6%. CONCLUSIONS: The IVH score is a valuable predictor of shunt-dependent H in patients with spontaneous supratentorial ICH. Its simplicity allows for easy integration into routine clinical practice, aiding in better patient risk stratification and informed decision-making regarding permanent CSF shunt placement.

Admission serum creatinine in non-hemodialysis-dependent patients with spontaneous supratentorial intracerebral hemorrhage: Is it a prognosticator?

INTRODUCTION: Spontaneous intracerebral hemorrhage (ICH) carries a high mortality rate, with end-stage renal disease (ESRD) and hemodialysis being risk factors for early mortality. However, the role of admission serum creatinine in ICH prognosis remains unclear. This study aimed to analyze the correlation between admission serum creatinine levels and short-term ICH prognosis in non-hemodialysis-dependent patients. METHODS: This retrospective study analyzed 296 adult patients admitted with spontaneous supratentorial ICH. Demographic, clinical, and radiographic data were collected, including admission serum creatinine levels. The primary outcomes were mortality and unfavorable outcomes, defined as Modified Rankin Scale scores of 4-6. Univariate or multivariate analysis was performed to examine the association between admission serum creatinine levels and ICH prognosis, with and without the inclusion of maintenance hemodialysis patients. RESULTS: Among all patients, elevated admission serum creatinine levels were significantly associated with increased mortality (OR = 1.39, 95% CI: 1.21-1.59, P < 0.01). However, this association disappeared when excluding patients undergoing maintenance hemodialysis (OR = 0.95, 95% CI: 0.53-1.69, P = 0.86). No significant association was found between admission serum creatinine levels and unfavorable outcomes. Other well-established prognostic factors, such as age and admission GCS, demonstrated significant associations with both mortality and unfavorable outcomes in multivariate analysis. CONCLUSION: Admission serum creatinine appears to have limited prognostic value in non-hemodialysis-dependent patients with spontaneous supratentorial ICH. Our findings suggest that the relationship between renal function and ICH prognosis is complex and may be influenced by factors such as comorbidities and maintenance hemodialysis.

Simultaneous cranioplasty and ventriculoperitoneal shunt placement in patients with traumatic brain injury undergoing unilateral decompressive craniectomy.

Hydrocephalus is a common complication after decompressive craniectomy (DC) in patients with traumatic brain injury (TBI). However, the strategy of managing TBI patients with a cranial defect and hydrocephalus remains controversial. Placement of a ventriculoperitoneal shunt (VPS) in patients with a cranial defect and hydrocephalus may aggravate sinking skin flap overlying the cranial defect and result in syndrome of sinking skin flap (SSSF) that causes neurological deterioration. A retrospective analysis of 49 TBI patients who developed hydrocephalus after unilateral DC was undertaken to investigate the safety of simultaneous cranioplasty and VPS placement, and the incidence of SSSF after VPS placement. Among these patients, 17 patients underwent simultaneous cranioplasty and VPS placement, and 32 patients underwent staged cranioplasty and VPS placement. The overall complication rate was 9.3% (3/32) in staged group and 29.4% (5/17) in simultaneous group, respectively. There was no statistically significance between two study groups regarding overall complication (p = 0.11) and reoperation rate (p = 0.47). Two patients with severe brain bulging in staged group developed SSSF after placement of a nonprogrammable VPS. Our study showed that simultaneous cranioplasty and VPS placement may be safe in TBI patients with a cranial defect and hydrocephalus. However, due to the contradictory results about the safety of simultaneous cranioplasty and VPS placement in the literatures, neurosurgeons should carefully consider whether patients are suitable for such treatment. In patients planning to undergo VPS placement first, a programmable shunt may be a better choice for the possibility of SSSF after shunt placement.
