Assessment of the effect of short-term factors on surgical treatments for hypertensive intracerebral haemorrhage

Natural history and surgical management of spontaneous intracerebral hemorrhage: a systematic review

INTRODUCTION

Management of spontaneous intracerebral hemorrhage (ICH) remains controversial despite efforts to produce high level evidence in the past few years. We systematically examined the pooled literature data on the natural history and surgical management of ICH.

EVIDENCE ACQUISITION

A systematic review was performed using the PubMed and Embase databases, encompassing English, full-text articles, reporting treatment outcomes for the conservative and surgical management of ICH.

EVIDENCE SYNTHESIS

A total of 91 studies met the eligibility criteria (total of 16,411 ICH cases). The most common locations for an ICH were the basal ganglia for both the conservative (68.7%) and surgical cohorts (58.4%). Patients in the non-operative group (40.5%) were older (mean age 62.9 years; range 12.0-94.0), had a higher Glasgow Coma Scale (GCS) score at presentation (mean GCS 10.2; range 3-15) and lower ICH volume (mean 36.9 mL). When managed non-operatively, a favorable functional outcome was encountered in 25.7% (95% CI 16.9-34.5) of patients, with a 22.2% (95% CI 16.6-27.8) mortality rate. Patients who underwent surgery (59.5%) were younger (mean age 58.8 years; range 12.0-94.0), had a lower GCS at presentation (mean GCS 8.2; range 3-15) and larger ICH volume (mean 58.3 mL; range 8.2-140.0). Craniotomy with hematoma evacuation was the preferred surgical technique (38.6%). A favorable functional outcome was encountered in 29.8% (95% CI 23.8-35.8) of operated patients, with a 21.3% (95% CI 16.3-26.3) mortality rate.

CONCLUSIONS

For many ICH cases, the reviewed literature allows to define surgical and conservative candidates. However, there are still some ICH-cases where management remains controversial.

Serum Copper Homeostasis in Hypertensive Intracerebral Hemorrhage and its Clinical Significance

This study was to investigate the alterations of serum copper homeostasis after hypertensive intracerebral hemorrhage (ICH), which is not yet clear. We recruited 85 hypertensive ICH patients and determined their serum levels of total copper (TCu), small molecule copper (SMC), and ceruloplasmin (Cp). Sera from 32 healthy persons and 12 primary hypertension patients were collected and analyzed as well. Serum TCu levels in ICH patients were tested at three time points (on admission, day 3, and day 7) and found to be higher than that in hypertension patients (p < 0.05). The serum SMC levels in hypertension patients and ICH patients at three time points were higher than that in healthy controls (p < 0.05). Higher serum SMC levels on days 3 and 7 were associated with death in the hospital. Additionally, higher serum SMC levels on the seventh day were associated with poor outcome at discharge. High serum Cp levels on admission, as well as low serum Cp levels on the seventh day, were associated with death in the hospital (p = 0.002 and p = 0.034, respectively). Our findings indicated that declines in serum Cp and increases in serum SMC are correlated with lethal or poor outcome in hypertensive ICH patients, possibly as a result of contributions to secondary injury of brain after hemorrhage due to impairment of iron transport and enhanced oxidative stress.

Prognostic Significance of Ultraearly Hematoma Growth in Spontaneous Intracerebral Hemorrhage Patients Receiving Hematoma Evacuation

OBJECTIVE

To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation.

METHODS

Supratentorial sICH patients receiving hematoma evacuation within 24 hours after ictus were enrolled in this study. uHG was defined as baseline hematoma volume/onset-to-computed tomography (CT) time (mL/h). The outcome was assessed by the modified Rankin Scale (mRS) score at 3 months. Unfavorable outcome was defined as mRS >2.

RESULTS

A total of 93 patients were enrolled in this study. The mean uHG was 10.3 ± 5.5 mL/h. In 69 (74.2%) of patients, the outcome was unfavorable at 3 months. The uHG in patients with unfavorable outcome were significantly higher than in those with favorable outcome (11.0 ± 6.1 mL/h vs. 8.3 ± 2.5 mL/h, P = 0.003). The optimal cutoff of uHG for predicting unfavorable outcome was 8.7 mL/h. The sensitivity, specificity, positive predictive value, and negative predictive value of uHG >8.7 mL/h for predicting unfavorable outcome were 56.5%, 75.0%, 86.7%, and 37.5%, respectively.

CONCLUSIONS

uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h.
