Minimally invasive puncture versus conventional craniotomy for spontaneous supratentorial hemorrhage: A meta-analysis

Minimally invasive surgeries for spontaneous hypertensive intracerebral hemorrhage (MISICH): a multicenter randomized controlled trial

BACKGROUND

Intracerebral hemorrhage (ICH) is a common stroke type with high morbidity and mortality. There are mainly three surgical methods for treating ICH. Unfortunately, thus far, no specific surgical method has been proven to be the most effective. We carried out this study to investigate whether minimally invasive surgeries with endoscopic surgery or stereotactic aspiration (frameless navigated aspiration) will improve functional outcomes in patients with supratentorial ICH compared with small-bone flap craniotomy.

METHODS

In this parallel-group multicenter randomized controlled trial conducted at 16 centers, patients with supratentorial hypertensive ICH were randomized to receive endoscopic surgery, stereotactic aspiration, or craniotomy at a 1:1:1 ratio from July 2016 to June 2022. The follow-up duration was 6 months. Patients were randomized to receive endoscopic evacuation, stereotactic aspiration, or small-bone flap craniotomy. The primary outcome was favorable functional outcome, defined as the proportion of patients who achieved a modified Rankin scale (mRS) score of 0-2 at the 6-month follow-up.

RESULTS

A total of 733 patients were randomly allocated to three groups: 243 to the endoscopy group, 247 to the aspiration group, and 243 to the craniotomy group. Finally, 721 patients (239 in the endoscopy group, 246 in the aspiration group, and 236 in the craniotomy group) received treatment and were included in the intention-to-treat analysis. Primary efficacy analysis revealed that 73 of 219 (33.3%) in the endoscopy group, 72 of 220 (32.7%) in the aspiration group, and 47 of 212 (22.2%) in the craniotomy group achieved favorable functional outcome at the 6-month follow-up (P = .017). We got similar results in subgroup analysis of deep hemorrhages, while in lobar hemorrhages the prognostic outcome was similar among three groups. Old age, deep hematoma location, large hematoma volume, low preoperative GCS score, craniotomy, and intracranial infection were associated with greater odds of unfavorable outcomes. The mean hospitalization expenses were ¥92,420 in the endoscopy group, ¥77,351 in the aspiration group, and ¥100,947 in the craniotomy group (P = .000).

CONCLUSIONS

Compared with small bone flap craniotomy, endoscopic surgery and stereotactic aspiration improved the long-term outcome of hypertensive ICH, especially deep hemorrhages.

Analysis of the Failure of Removal of the Urinary Catheter for Patients With Intracerebral Hemorrhage Postoperatively

BACKGROUND

We conducted this study to assess the value of clinically relevant data for predicting the failure of removing urinary catheters among patients with intracerebral hemorrhage postoperatively.

MATERIALS AND METHODS

We retrospectively analyzed the medical records of all patients with intracerebral hemorrhage who underwent surgery for removal of intracerebral hematoma between January 2014 and December 2019, all of whom retained their urinary catheter. The patients were classified into 2 groups. Group A included patients who underwent successful removal of the catheter while group B included patients who underwent a failed removal. Univariate analysis was performed to determine the relationship between the failure of catheter removal and the patients' preoperative clinical characteristics. Independent prognostic predictors were identified using multivariate analyses.

RESULTS

The site of intracerebral hematoma ( P =0.004), volume of hematoma ( P <0.001), intraventricular hemorrhage ( P <0.001), admitted Glasgow Coma Scale (GCS) ( P <0.001), GCS before urinary catheter removal ( P <0.001), smoking ( P =0.011), herniation ( P <0.001), urine protein ( P =0.013), creatinine ( P =0.037), and timing of urinary catheter removal ( P <0.001) were significantly different among the 2 groups. Multiple logistical regression analysis indicated that GCS before urinary catheter removal (odds ratio=1.171; 95% confidence interval=1.050-1.306; P =0.005) and timing for urinary catheter removal (odds ratio=0.962; 95% confidence interval=0.944-0.981; P <0.001) were associated with failure of urinary catheter removal.

CONCLUSIONS

This study demonstrated that GCS before urinary catheter removal and the timing of urinary catheter removal are independent factors associated with failure of urinary catheter removal among patients with intracerebral hemorrhage.

Prognostic data analysis of surgical treatments for intracerebral hemorrhage

Spontaneous intracerebral hemorrhage (ICH) is a commonly occurring disease in neurosurgery, yet its surgical treatment is controversial. This paper pertains to the study of the effects of different treatment regimens on the outcome of ICH population. Based on a globally shared third-party MIMIC-III database, the researchers firstly described the dissimilarities in survival probability, mortality, and neurological recovery among mainstream treatments for ICH; secondly, patient classification was determined by important clinical features; and outcome variations among treatment groups were compared. The 28-day, 90-day, and in-hospital mortality in the craniotomy group were significantly lower than minimally invasive surgery (MIS) and non-surgical group patients; and, the medium/long-term mortality in MIS group was significantly lower than the non-surgical group. The craniotomy group positively correlated with short-term GCS recovery compared with the MIS group; no difference existed between the non-surgical and MIS groups. The craniotomy group 90-day survival probability and short-term GCS recovery were superior to the other two treatments in the subgroups of first GCS 3-12; this tendency also presented in the MIS group over non-surgical group. For milder patients (first GCS > 12), the three treatment regimens had a minimal effect on patient survival, but the non-surgical group showed an advantage in short-term GCS recovery. Craniotomy patients have a lower mortality and a better short-term neurological recovery in an ICH population, especially in short-to-medium term mortality and short-term neurological recovery over MIS patients. In addition, surgical treatment is recommendable for patients with a GCS ≤ 12.
