Clinical efficacy and safety of neuroendoscopic surgery for severe thalamic hemorrhage with ventricle encroachment

European Stroke Organisation (ESO) and European Association of Neurosurgical Societies (EANS) guideline on stroke due to spontaneous intracerebral haemorrhage

Spontaneous (non-traumatic) intracerebral haemorrhage (ICH) affects ~3.4 million people worldwide each year, causing ~2.8 million deaths. Many randomised controlled trials and high-quality observational studies have added to the evidence base for the management of people with ICH since the last European Stroke Organisation (ESO) guidelines for the management of spontaneous ICH were published in 2014, so we updated the ESO guideline. This guideline update was guided by the European Stroke Organisation (ESO) standard operating procedures for guidelines and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework, in collaboration with the European Association of Neurosurgical Societies (EANS). We identified 37 Population, Intervention, Comparator, Outcome (PICO) questions and prioritised clinical outcomes. We conducted systematic literature searches, tailored to each PICO, seeking randomised controlled trials (RCT) - or observational studies when RCTs were not appropriate, or not available - that investigated interventions to improve clinical outcomes. A group of co-authors allocated to each PICO screened titles, abstracts, and full texts and extracted data from included studies. A methodologist conducted study-level meta-analyses and created summaries of findings tables. The same group of co-authors graded the quality of evidence, and drafted recommendations that were reviewed, revised and approved by the entire group. When there was insufficient evidence to make a recommendation, each group of co-authors drafted an expert consensus statement, which was reviewed, revised and voted on by the entire group. The systematic literature search revealed 115,647 articles. We included 208 studies. We found strong evidence for treatment of people with ICH on organised stroke units, and secondary prevention of stroke with blood pressure lowering. We found weak evidence for scores for predicting macrovascular causes underlying ICH; acute blood pressure lowering; open surgery via craniotomy for supratentorial ICH; minimally invasive surgery for supratentorial ICH; decompressive surgery for deep supratentorial ICH; evacuation of cerebellar ICH > 15 mL; external ventricular drainage with intraventricular thrombolysis for intraventricular extension; minimally invasive surgical evacuation of intraventricular blood; intermittent pneumatic compression to prevent proximal deep vein thrombosis; antiplatelet therapy for a licensed indication for secondary prevention; and applying a care bundle. We found strong evidence against anti-inflammatory drug use outside of clinical trials. We found weak evidence against routine use of rFVIIa, platelet transfusions for antiplatelet-associated ICH, general policies that limit treatment within 24 h of ICH onset, temperature and glucose management as single measures (outside of care bundles), prophylactic anti-seizures medicines, and prophylactic use of temperature-lowering measures, prokinetic anti-emetics, and/or antibiotics. New evidence about the management of ICH has emerged since 2014, enabling this update of the ESO guideline to provide new recommendations and consensus statements. Although we made strong recommendations for and against a few interventions, we were only able to make weak recommendations for and against many others, or produce consensus statements where the evidence was insufficient to guide clinical decisions. Although progress has been made, many interventions still require definitive, high-quality evidence, underpinning the need for embedding clinical trials in routine clinical practice for ICH.

Minimally Invasive Puncture and Drainage Surgery for the Treatment of Thalamic Hemorrhage Guided by a 3D-printed Guide Plate

Thalamic hemorrhage is a type of intracerebral hemorrhage with high disability and mortality rates. Because of its deep bleeding location, irregular shape of the hematoma, and compression of the third ventricle, it is not suitable for craniotomy. This paper reports a case of a 63-year-old male patient who sought medical attention for left-sided basal ganglia and thalamus hemorrhage that broke into the ventricles. Upon admission, the patient exhibited impaired consciousness and was diagnosed with thalamic hemorrhage accompanied by ventricular hemorrhage through the head CT and CTA scan. To address the patient's unique circumstances, a 3D-printed guide plate was utilized to guide the puncture and drainage surgery, thereby ensuring a relatively smooth and less traumatic process. After the surgery, the patient's consciousness recovered well, and there was significant improvement in clinical indicators. This case demonstrates that a 3D-printed guide plate has the advantage of precise localization and minimal trauma in guiding thalamic hemorrhage surgery, showing promising clinical application prospects and being worthy of promotion in future clinical practice.

Analysis of the Efficacy of Neuroendoscopic Hematoma Removal Combined With Ventricular Lavage in Severe Intraventricular Hemorrhage-A Prospective Randomized Controlled Study

BACKGROUND AND OBJECTIVES

The current widely utilized clinical approach for severe intraventricular hemorrhage involves ventriculostomy with supportive drainage. The aim of our study was to evaluate the overall efficacy of neuroendoscopic hematoma removal combined with ventricular lavage as a treatment approach for severe intraventricular hemorrhage.

METHODS

A prospective randomized controlled study was conducted, selecting a total of 98 patients with severe intraventricular hemorrhage at our hospital from February 2021 to November 2022. The patients were randomly distributed into 2 groups using a randomized number table method: the neuroendoscopic group (undergoing neuroendoscopic hematoma removal combined with ventricular lavage) and the control group (undergoing intraventricular trepanation and drainage), with 49 patients in each group.

RESULTS

The neuroendoscopic group had significantly higher intraoperative blood loss than that of the control group ( P = .037), while the drainage tube indwelling time and hospital stay in the neuroendoscopic group were significantly shorter ( P < .001). At 6 hours ( P = .021), 1 day ( P = .002), 3 days ( P < .001) and 7 days ( P = .007) following surgery, the neuroendoscopic group exhibited evidently higher hematoma clearance rates compared with the control group. At 1 day and 3 days after surgery, the cerebrospinal fluid drainage volume in the neuroendoscopic group was significantly higher than that in the control group ( P < .001), whereas at 7 days after surgery, it was significantly lower in the neuroendoscopic group compared with the control group ( P < .001). Moreover, significantly lower incidence of intracranial infection ( P = .045) and increased intracranial pressure ( P = .008) was observed in the neuroendoscopic group compared with the control group.

CONCLUSION

Neuroendoscopic hematoma removal combined with ventricle lavage emerged as an effective treatment strategy for severe intraventricular hemorrhage, yielding significant therapeutic benefits. Therefore, this approach holds promise for broader clinical application and promotion.

The efficacy of neuroendoscopic surgery treating patients with thalamic hemorrhage accompanied by intraventricular hematoma

Objective

Neuroendoscopic surgery (NES) has been proven to be safe and effective in hematoma evacuation for cerebral hemorrhage. However, its efficacy for thalamic hemorrhage accompanied by intraventricular hematoma (THAVH) remains unclear. The aim of this study is to determine the efficacy of NES in treating THAVH.

Method

A retrospective study was carried out. The data of patients diagnosed with THAVH were collected from January 1st, 2019, to January 1st, 2022. Patients received the NES or external ventricle drainage (EVD) treatment were assigned to the NES or EVD group, respectively. As primary outcomes, the hematoma evacuation volume, residual hematoma volume, and hematoma clearance rate were separately calculated based on the hematoma site; and the 180-day-mRS score was assessed. As secondary outcomes, the length of stay in the ICU and hospital, and the adverse events were also compared.

Results

Thirty-five patients, aged 66.37 ± 6.62 years, were in the NES group; and 40 patients, aged 68.75 ± 7.22 years, were in the EVD group. The baseline characteristics in the two groups were similar (P > 0.05). The gross hematoma evacuation volume, volume of hematoma evacuated in the thalamus or the ventricle, and the hematoma clearance rate were greater in the NES group than in the EVD group on the 1st day after surgery (P < 0.05). The patients had a better rank of mRS in the NES group (P < 0.05). Compared with patients with mRS > 3, the mean residual hematoma volume in the thalamus of patients with mRS ≤3 on the 1st and 7th day were less in each group (P < 0.05), respectively. A residual hematoma volume in the ventricle of patients with mRS ≤3 was less than that of patients with mRS >3 in the EVD group on the 1st day after surgery (P < 0.05). GCS score on the 3rd day was greater in the NES group (P < 0.05). The incidence of lung infection was lower in the NES group (P < 0.05). The length of stay in the ICU and hospitalization duration were shorter in the NES group (P < 0.05).

Conclusions

Neuroendoscopic surgery has a greater hematoma clearance rate, a lower lung infection rate and a shorter duration in the hospital. Neuroendoscopic surgery might improve patients' prognosis. Neuroendoscopic surgery is a safe and effective procedure for treating thalamic hemorrhage accompanied by intraventricular hematoma.

Traditional craniotomy versus current minimally invasive surgery for spontaneous supratentorial intracerebral haemorrhage: A propensity-matched analysis

BACKGROUND

Minimally invasive surgery (MIS) and craniotomy (CI) are the current treatments for spontaneous supratentorial cerebral haemorrhage (SSTICH).

AIM

To compare the efficacy and safety of MIS and CI for the treatment of SSTICH.

METHODS

Clinical and imaging data of 557 consecutive patients with SSTICH who underwent MIS or CI between January 2017 and December 2022 were retrospectively analysed. The patients were divided into two subgroups: The MIS group and CI group. Propensity score matching was performed to minimise case selection bias. The primary outcome was a dichotomous prognostic (favourable or unfavourable) outcome based on the modified Rankin Scale (mRS) score at 3 months; an mRS score of 0-2 was considered favourable.

RESULTS

In both conventional statistical and binary logistic regression analyses, the MIS group had a better outcome. The outcome of propensity score matching was unexpected (odds ratio: 0.582; 95%CI: 0.281-1.204; P = 0.144), which indicated that, after excluding the interference of each confounder, different surgical modalities were more effective, and there was no significant difference in their prognosis.

CONCLUSION

Deciding between MIS and CI should be made based on the individual patient, considering the hematoma size, degree of midline shift, cerebral swelling, and preoperative Glasgow Coma Scale score.

The Usefulness of the 3.1-mm-diameter 4K Rigid Endoscope for Intracerebral Hematoma Evacuation

The indication for surgical intervention in spontaneous intracerebral hemorrhage remains controversial. Although many clinical trials have failed to demonstrate its efficacy over medical treatment, less invasive endoscopic treatment is expected to demonstrate its superiority. A novel endoscopic system for hematoma removal consisting of a 3.1-mm-diameter 4K high-resolution rigid endoscope was used.The system was used in eight cases of spontaneous intracerebral hemorrhage. It provided improved maneuverability of the surgical instrument while maintaining satisfactory image quality. The surgical goal was achieved in all cases without any complications, including perioperative rebleeding.Endoscopic hematoma removal using the 3.1 mm high-resolution endoscope is an alternative minimally invasive approach to spontaneous intracerebral hemorrhage with improved reliability.

Clinical Efficacy of Neuroendoscopy Combined with Intracranial Pressure Monitoring for the Treatment of Hypertensive Intracerebral Hemorrhage

OBJECTIVE

To compare the differences in postoperative complications and prognosis between patients treated with neuroendoscopy versus conventional craniotomy surgery for hypertensive intracerebral hemorrhage (HICH).

METHODS

In this retrospective study, a total of 107 patients with HICH were included. Among them, 58 underwent neuroendoscopy (Group A), while 49 underwent conventional craniotomy under microscopic guidance (Group B). Intracranial pressure monitoring was applied in both groups. The clinical data, incidence of postoperative complications, preoperative and postoperative intracranial pressure values, and rate of favorable prognosis were compared between the 2 groups.

RESULTS

No significant difference in baseline clinical data upon admission was observed between the 2 groups (P > 0.05). The preoperative intracranial pressure did not differ between the 2 groups (P > 0.05), but the postoperative intracranial pressure in Group A was significantly lower than that in Group B (P < 0.05). After intervention with the different surgical approaches, Group A showed a significantly lower incidence of postoperative cerebral infarction and a significantly higher rate of favorable prognosis compared with Group B (P < 0.05).

CONCLUSIONS

Neuroendoscopy combined with Intracranial pressure monitoring is a safe and reliable approach for the treatment of HICH that reduces the incidence of postoperative cerebral infarction and improves the recovery of neurological function after surgery.

The long-term effect on functional outcome of endoscopic brainwashing for intraventricular hemorrhage compared to external ventricular drainage alone: A retrospective single-center cohort study

Background

Intraventricular hemorrhage (IVH) is a complex condition with both mechanical and chemical effects, resulting in mortality rates of 50-80%. Recent reports advocate for neuroendoscopic treatment, particularly endoscopic brainwashing (EBW), but long-term functional outcomes remain insufficiently explored. This study aims to outline the step-by-step procedure of EBW as applied in our institution, providing results and comparing them with those of external ventricular drainage (EVD) alone.

Methods

We performed a retrospective analysis of adult patients with IVH who underwent EBW and patients submitted to EVD alone at our institution. All medical records were reviewed to describe clinical and radiological characteristics.

Results

Although both groups had similar baseline factors, EBW patients exhibited a larger hemoventricle (median Graeb score 25 vs. 23 in EVD, P = 0.03) and a higher prevalence of chronic kidney disease and diabetes. Short-term mortality was lower in EBW (52% and 60% at 1 and 6 months) compared to EVD (80% for both), though not statistically significant (P = 0.06). At one month, 16% of EBW patients achieved a good outcome (Modified Rankin scale < 3) versus none in the EVD group (P = 0.1). In the long term, favorable outcomes were observed in 32% of EBW patients and 11% of EVD patients (P = 0.03), with no significant difference in shunt dependency.

Conclusion

Comparing EBW and EVD, patients submitted to the former treatment have the highest modified Graeb scores and, at a long-term follow-up, have better outcomes, demonstrated by the improvement of the patients in the follow-up.

Comparison of the efficacy of neuronavigation-assisted intracerebral hematoma puncture and drainage with neuroendoscopic hematoma removal in treatment of hypertensive cerebral hemorrhage

OBJECTIVE

To compare neuronavigation-assisted intracerebral hematoma puncture and drainage with neuroendoscopic hematoma removal for treatment of hypertensive cerebral hemorrhage.

METHOD

Ninety-one patients with hypertensive cerebral hemorrhage admitted to our neurosurgery department from June 2022 to May 2023 were selected: 47 patients who underwent endoscopic hematoma removal with the aid of neuronavigation in observation Group A and 44 who underwent intracerebral hematoma puncture and drainage in control Group B. The duration of surgery, intraoperative bleeding, hematoma clearance rate, pre- and postoperative GCS score, National Institutes of Health Stroke Scale (NIHSS) score, mRS score and postoperative complications were compared between the two groups.

RESULTS

The duration of surgery, intraoperative bleeding and hematoma clearance were significantly lower in Group B than in Group A (p < 0.05). Conversely, no significant differences in the preoperative, 7-day postoperative, 14-day postoperative or 1-month postoperative GCS or NIHSS scores or the posthealing mRS score were observed between Groups A and B. However, the incidence of postoperative complications was significantly greater in Group B than in Group A (p < 0.05), with the most significant difference in incidence of intracranial infection (p < 0.05).

CONCLUSION

Both neuronavigation-assisted intracerebral hematoma puncture and drainage and neuroendoscopic hematoma removal are effective at improving the outcome of patients with hypertensive cerebral hemorrhage. The disadvantage of neuronavigation is that the incidence of complications is significantly greater than that of other methods; postoperative care and prevention of complications should be strengthened in clinical practice.

Neuroendoscopic Evacuation Improves Outcomes Compared with External Ventricular Drainage in Patients with Spontaneous Intraventricular Hemorrhage: A Systematic Review with Meta-Analyses

BACKGROUND

Spontaneous intraventricular hemorrhage (IVH) is a cause of significant morbidity and mortality. Treatment for resulting obstructive hydrocephalus has traditionally been via an external ventricular drain (EVD). We aimed to compare patient outcomes after neuroendoscopic surgery (NES) evacuation of IVH versus EVD management.

METHODS

MEDLINE, Embase, and Cochrane Library databases were searched on October 8, 2022. Of the 252 records remaining after removal of duplicates, 12 met study inclusion criteria. After extraction of outcomes data, fixed-effect and random-effects models were used to establish odds ratios (ORs) with 95% confidence intervals (CIs) for intensive care unit length of stay, rate of permanent cerebrospinal fluid diversion, Glasgow Outcome Scale score, and mortality rate.

RESULTS

The results of the pooled analysis showed that intensive care unit length of stay was shorter (OR -2.61 [95% CI -5.02, -0.19]; I2 = 97.76%; P = 0.034), permanent cerebrospinal fluid diversion was less likely (OR -0.79, 95% CI [-1.17, -0.41], I2 = 46.96%, P < 0.001), higher Glasgow Outcome Scale score was more likely (OR 0.48, 95% CI [0.04, 0.93], I2 = 60.12%, P = 0.032), and all-cause mortality was less likely (OR -1.11, 95% CI [-1.79, -0.44], I2 = 0%, P = 0.001) in the NES evacuation group compared with the EVD group.

CONCLUSIONS

NES for evacuation of spontaneous IVH results in reduced intensive care unit length of stay, reduced permanent cerebrospinal fluid diversion rates, improved Glasgow Outcome Scale score, and reduced mortality when compared with EVD. More robust prospective, randomized studies are necessary to help inform the safety and utility of NES for IVH.
