RESUMO
BACKGROUND: Evaluating the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH) who may be at risk of poor outcomes using grading systems is one way to make a better decision on treatment for these patients. This study aimed to compare the accuracy of the modified World Federation of Neurosurgical Societies (WFNS), WFNS, and Hunt and Hess (H&H) Grading Scales in predicting the outcomes of patients with aSAH. METHODS: From August 2019 to June 2021, we conducted a multicenter prospective cohort study on adult patients with aSAH in three central hospitals in Hanoi, Vietnam. The primary outcome was the 90-day poor outcome, measured by a score of 4 (moderately severe disability) to 6 (death) on the modified Rankin Scale (mRS). We calculated the areas under the receiver operator characteristic (ROC) curve (AUROCs) to determine how well the grading scales could predict patient prognosis upon admission. We also used ROC curve analysis to find the best cut-off value for each scale. We compared AUROCs using Z-statistics and compared 90-day mean mRS scores among intergrades using the pairwise multiple-comparison test. Finally, we used logistic regression to identify factors associated with the 90-day poor outcome. RESULTS: Of 415 patients, 32% had a 90-day poor outcome. The modified WFNS (AUROC: 0.839 [95% confidence interval, CI: 0.795-0.883]; cut-off value≥2.50; PAUROC<0.001), WFNS (AUROC: 0.837 [95% CI: 0.793-0.881]; cut-off value≥3.5; PAUROC<0.001), and H&H scales (AUROC: 0.836 [95% CI: 0.791-0.881]; cut-off value≥3.5; PAUROC<0.001) were all good at predicting patient prognosis on day 90th after ictus. However, there were no significant differences between the AUROCs of these scales. Only grades IV and V of the modified WFNS (3.75 [standard deviation, SD: 2.46] vs 5.24 [SD: 1.68], p = 0.026, respectively), WFNS (3.75 [SD: 2.46] vs 5.24 [SD: 1.68], p = 0.026, respectively), and H&H scales (2.96 [SD: 2.60] vs 4.97 [SD: 1.87], p<0.001, respectively) showed a significant difference in the 90-day mean mRS scores. In multivariable models, with the same set of confounding variables, the modified WFNS grade of III to V (adjusted odds ratio, AOR: 9.090; 95% CI: 3.494-23.648; P<0.001) was more strongly associated with the increased risk of the 90-day poor outcome compared to the WFNS grade of IV to V (AOR: 6.383; 95% CI: 2.661-15.310; P<0.001) or the H&H grade of IV to V (AOR: 6.146; 95% CI: 2.584-14.620; P<0.001). CONCLUSIONS: In this study, the modified WFNS, WFNS, and H&H scales all had good discriminatory abilities for the prognosis of patients with aSAH. Because of the better effect size in predicting poor outcomes, the modified WFNS scale seems preferable to the WFNS and H&H scales.

This multicentre prospective cohort study aimed to compare the accuracy of the PAASH, WFNS, and Hunt and Hess (H&H) scales in predicting the outcomes of adult patients with aneurysmal SAH presented to three central hospitals in Hanoi, Vietnam, from August 2019 to June 2021. Of 415 eligible patients, 32.0% had a 90-day poor outcome, defined as an mRS score of 4 (moderately severe disability) to 6 (death). The PAASH, WFNS and H&H scales all have good discriminatory abilities for predicting the 90-day poor outcome. There were significant differences in the 90-day mean mRS scores between grades I and II (p = 0.001) and grades II and III (p = 0.001) of the PAASH scale, between grades IV and V (p = 0.026) of the WFNS scale, and between grades IV and V (p < 0.001) of the H&H scale. In contrast to a WFNS grade of IV-V and an H&H grade of IV-V, a PAASH grade of III-V was an independent predictor of the 90-day poor outcome. Because of the more clearly significant difference between the outcomes of the adjacent grades and the more strong effect size for predicting poor outcomes, the PAASH scale was preferable to the WFNS and H&H scales.

OBJECTIVES: To investigate the impact of intracerebral haematoma (ICH) on the outcomes and the factors related to an ICH in patients with aneurysmal subarachnoid haemorrhage (aSAH) in a low- and middle-income country. DESIGN: A multicentre prospective cohort study. SETTING: Three central hospitals in Hanoi, Vietnam. PARTICIPANTS: This study included all patients (≥18 years) presenting with aSAH to the three central hospitals within 4 days of ictus, from August 2019 to June 2021, and excluded patients for whom the admission Glasgow Coma Scale was unable to be scored or patients who became lost at 90 days of follow-up during the study. OUTCOME MEASURES: The primary outcome was ICH after aneurysm rupture, defined as ICH detected on an admission head CT scan. The secondary outcomes were 90-day poor outcomes and 90-day death. RESULTS: Of 415 patients, 217 (52.3%) were females, and the median age was 57.0 years (IQR: 48.0-67.0). ICH was present in 20.5% (85/415) of patients with aSAH. There was a significant difference in the 90-day poor outcomes (43.5% (37/85) and 29.1% (96/330); p=0.011) and 90-day mortality (36.5% (31/85) and 20.0% (66/330); p=0.001) between patients who had ICH and patients who did not have ICH. The multivariable regression analysis showed that systolic blood pressure (SBP) ≥140 mm Hg (adjusted odds ratio (AOR): 2.674; 95% CI: 1.372 to 5.214; p=0.004), World Federation of Neurosurgical Societies (WFNS) grades II (AOR: 3.683; 95% CI: 1.250 to 10.858; p=0.018) to V (AOR: 6.912; 95% CI: 2.553 to 18.709; p<0.001) and a ruptured middle cerebral artery (MCA) aneurysm (AOR: 3.717; 95% CI: 1.848 to 7.477; p<0.001) were independently associated with ICH on admission. CONCLUSIONS: In this study, ICH was present in a substantial proportion of patients with aSAH and contributed significantly to a high rate of poor outcomes and death. Higher SBP, worse WFNS grades and ruptured MCA aneurysms were independently associated with ICH on admission.

BACKGROUND: The prevalence of risk factors for poor outcomes from aneurysmal subarachnoid hemorrhage (SAH) varies widely and has not been fully elucidated to date in Vietnam. Understanding the risk and prognosis of aneurysmal SAH is important to reduce poor outcomes in Vietnam. The aim of this study, therefore, was to investigate the rate of poor outcome at 90 days of ictus and associated factors from aneurysmal SAH in the country. METHODS: We performed a multicenter prospective cohort study of patients (≥18 years) presenting with aneurysmal SAH to three central hospitals in Hanoi, Vietnam, from August 2019 to August 2020. We collected data on the characteristics, management, and outcomes of patients with aneurysmal SAH and compared these data between good (defined as modified Rankin Scale (mRS) of 0 to 3) and poor (mRS, 4-6) outcomes at 90 days of ictus. We assessed factors associated with poor outcomes using logistic regression analysis. RESULTS: Of 168 patients with aneurysmal SAH, 77/168 (45.8%) were men, and the median age was 57 years (IQR: 48-67). Up to 57/168 (33.9%) of these patients had poor outcomes at 90 days of ictus. Most patients underwent sudden-onset and severe headache (87.5%; 147/168) and were transferred from local to participating central hospitals (80.4%, 135/168), over half (57.1%, 92/161) of whom arrived in central hospitals after 24 hours of ictus, and the initial median World Federation of Neurological Surgeons (WFNS) grading score was 2 (IQR: 1-4). Nearly half of the patients (47.0%; 79/168) were treated with endovascular coiling, 37.5% (63/168) were treated with surgical clipping, the remaining patients (15.5%; 26/168) did not receive aneurysm repair, and late rebleeding and delayed cerebral ischemia (DCI) occurred in 6.1% (10/164) and 10.4% (17/163) of patients, respectively. An initial WFNS grade of IV (odds ratio, OR: 15.285; 95% confidence interval, CI: 3.096-75.466) and a grade of V (OR: 162.965; 95% CI: 9.975-2662.318) were independently associated with poor outcomes. Additionally, both endovascular coiling (OR: 0.033; 95% CI: 0.005-0.235) and surgical clipping (OR: 0.046; 95% CI: 0.006-0.370) were inversely and independently associated with poor outcome. Late rebleeding (OR: 97.624; 95% CI: 5.653-1686.010) and DCI (OR: 15.209; 95% CI: 2.321-99.673) were also independently associated with poor outcome. CONCLUSIONS: Improvements are needed in the management of aneurysmal SAH in Vietnam, such as increasing the number of aneurysm repairs, performing earlier aneurysm treatment by surgical clipping or endovascular coiling, and improving both aneurysm repairs and neurocritical care.

INTRODUCTION AND IMPORTANCE: Extracranial meningiomas are rare, accounting for 1-2% of all meningiomas with just published in the form of a case report or series. They are categorized as primary or secondary tumors. In this paper, we present a case of extracranial meningioma in the scalp skin, which is believed in Vietnam's first case. CASE PRESENTATION: A 38 years old male with a history of brain epidural hematoma surgery in 1995 presented a subcutaneous protruding mass, which revealed approximately 3-centimeters from an incision scar in the left frontoparietal scalp. The tumor was firm, mobilized with contrast enhancement on magnetic resonance image. The complete surgical excision of the whole mass was performed, and histological examination revealed a WHO grade I meningioma. CLINICAL DISCUSSION: Epidemiology, classification, diagnosis, treatment as well as prognosis of extracranial meningioma were discussed. We also hypothesized the emergence of extracranial meningioma after an epidural hematoma surgery. CONCLUSION: Extracranial meningioma is quite rare, but it could be presented after a traumatic brain injury. Neurosurgery was the first choice, safe and effective treatment.
RESUMO
INTRODUCTION: Pediatric intracranial aneurysms are rare, with some different characteristics from those in adults. Here, we present a case of distal anterior cerebral artery aneurysm which we believe the first case from Vietnam. PRESENTATION OF CASE: A 3 years old boy presented with headache, lethargic and hemiparesis was diagnosed ruptured distal anterior cerebral artery aneurysm with CTA. 10 days before admission in our hospital, the toddler was admitted in local hospital with diagnosis of SAH without more accurate findings. Clipping microsurgery of aneurysms with left interhemispheric approach was done with good outcome. DISCUSSION: The epidermiology, presentation and diagnosis and strategy of treatments as well as their outcomes were discussed. We also discussed our thoughts about our case within the limited-resource condition such as in Vietnam. CONCLUSION: Pediatric intracranial anerusyms are rare but should be recognised in neurosurgical practice. Surgery is an effective treatment method.
RESUMO
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.

INTRODUCTION: Sphenoid meningioma engulfed cerebral arteries has always been a challenge. To achieve a gross total resection, vessel sacrifice may be unavoidable. PRESENTATION OF CASE: A 22-year-old man with a history of head trauma a week ago complained of a headache for one week. On examination, he was alert, denied paralysis and cranial nerves palsies. Preoperative MRI showed a hypervascular left sphenoid wing meningioma embedding left internal carotid artery and proximal segment of the middle cerebral artery. In operation, a branch of the MCA was divided when dissecting the tumor. The MCA was clipped but was still difficult to dissect vessel ends in the Sylvian fissure. We decided to extend craniotomy and did superficial temporal artery to M4 segment of MCA bypass. Then, the patient was resuscitated in surgical high dependency unit for 3 days. Surgical outcome in one year postoperative was good with KPS 90 out of 100 points and no neurological deficits. On postoperative MRA, STA-MCA bypass shown acceptable flow. DISCUSSION: There were a few cases of skull base tumors requiring vessel revascularization. Most of the revascularization cases were meningiomas. Saphenous vein graft (SVGs) was the most commonly reported graft, followed by radial artery graft (RAGs). In case of difficulty in dissecting the vessel ends due to the tumor infiltration, STA-MCA bypass was a safe and helpful choice, especially the collateral vessels were present and the need for blood flow augmentation was minimal. CONCLUSION: STA-MCA bypass was effective surgical management for MCA injury in sphenoid wing meningioma resection.
