Clinico-radiological correlation with outcome in acute epidural haematoma: a tertiary centre experience from Nepal.

Background: Epidural haematoma (EDH) accounts for up to 15% of severe traumatic brain injury (TBI) cases and remains the most common cause of mortality and disability. Several clinical and radiological factors affect patient outcomes. This study aims to correlate patients' clinical and radiological profiles with acute EDH outcomes. Methods: A retrospective, single-centred, consecutive case series was conducted on the patients diagnosed with an acute EDH admitted to Tribhuvan University Teaching Hospital (TUTH) between May 2019 and April 2023. The modified Rankin scale (mRS) was used to assess the outcome. Univariate analysis and Kruskal-Wallis H test with Dunn-Bonferroni post-hoc test was conducted. Results: There were 107 patients diagnosed with EDH, of which 52.3% were less than 20 years old with male preponderance. Falls were the most common mechanism of injury (64.5%), and most cases were referred to, not brought directly. The majority had a GCS score greater than or equal to 13 (85%) at presentation, and only 5.5% had a GCS score less than or equal to 8. According to the mRS, most patients had favourable outcomes, with 88.7% having no significant disability and 11.3% having a slight disability. Conclusion: This case series is the largest and most recent report from Nepal and demonstrated that GCS, pupillary response, skull fracture, neurological symptoms, pre-hospital and intra-hospital delay, and management modalities are critical factors in determining the total hospital and ICU stay but did not have an impact on the mRS scores.

Middle meningeal artery embolization for chronic subdural hematoma refractory to Burr hole surgery: A case report.

Middle meningeal artery embolization is a valuable alternative for chronic subdural hematoma refractory to Burr hole surgery. In a 61-year-old patient, this endovascular intervention effectively resolved the hematoma alleviating associated symptoms.

Microsurgical treatment of posterior circulation aneurysms: an institutional experience from Nepal.

Background: Management strategies and outcomes of patients with posterior circulation aneurysms are varied due to uncertainty in the optimal treatment modality and limited experience of neurosurgeons. Data are scarce regarding patients with posterior circulation aneurysms from developing countries. This study aims to describe the clinical characteristics, management strategies and outcome of patients with these aneurysms treated microsurgically in an academic institute in Nepal. Methods: The clinical records of patients confirmed to have posterior circulation aneurysms treated microsurgically between July 2014 and July 2022 were retrospectively reviewed. Demographic and clinical characteristics, morphometric characteristics of aneurysms, management strategies, postoperative complications, and 1-year outcomes were described. Results: Out of 220 aneurysms in 190 patients, 20 were posterior circulation aneurysms. The median age of the patients was 43 (15-60) years. All were ruptured aneurysms. The admission Hunt and Hess grades of 18 (90%) patients were less than or equal to III. The posterior inferior cerebellar artery (8) was the commonest location. The postoperative complications rate was 20%, with the overall mortality of 10%. 80% of patients had a favourable outcome at 1-year follow-up. Conclusions: The patient characteristics and outcome are comparable with those described in the literature from other countries. With an individualized and careful selection strategy, our results are satisfactory despite fewer operations.

Academic neurosurgery in Nepal: Present status and future directions.

Introduction: The establishment of local neurosurgery training programs in Nepal has proven critical for the expansion of the discipline across the country. This paper aims to describe the evolution, current status, challenges, and future directions of academic neurosurgery in Nepal. Research question: What is the current status and international standing of academic neurosurgery in Nepal? Material and methods: Information related to growth and development in Nepal was obtained from universities and regulatory bodies in Nepal. Variables described are the current number of neurosurgeons, the number of neurosurgical centers and centers with accreditation for training, the description of existing training models, the number of graduates, and the contribution of Nepalese neurosurgeons to world literature. Results: Formal neurosurgical training started in Nepal in 1999. Of 67 hospitals with neurosurgical facilities, 10 (14.9%) are accredited. Three training models (MCh, NBMS, and FCPS) currently exist. Of 116 neurosurgeons currently practicing in the country, 47 (40.5%) are homegrown. The contribution of the Nepalese neurosurgical community to the world includes the training of the first two Maldivian neurosurgeons and an increasing presence in world neurosurgical literature. Conclusions: Although comparable to other countries with similar economies, Nepal still faces some challenges to the sustainability and further developments of Neurosurgery. Continued concerted efforts will help Nepalese neurosurgeons achieve the goal of securing self-reliance in neurosurgical education.

Changes in Electrocardiogram in Patients With Spontaneous Subarachnoid Hemorrhage: A Cross-Sectional Study.

Background Electrocardiographic (ECG) changes are frequently reported findings in patients with subarachnoid hemorrhage (SAH). We conducted a retrospective descriptive study to assess the prevalence of electrocardiographic changes in patients with non-traumatic SAH.  Methods In this single-center retrospective cross-sectional study, ECG recordings of 45 patients who presented to Tribhuvan University Teaching Hospital in the year 2019 with SAH were collected and analyzed to detect any abnormalities.  Results In our study, 88.8% of patients had some form of ECG abnormality. The most common ECG abnormalities associated with SAH were QTc prolongation, T-wave abnormalities, and bradycardia, which were found, respectively, in 35.5%, 24.4%, and 24.4% of the patients. Other ECG changes we observed include ST depression, large U-waves, atrial fibrillation, and premature ventricular contractions. Conclusion Morphological and rhythm abnormalities are frequently observed in patients with SAH, which may cause diagnostic dilemmas and unnecessary workups. Further studies are required to evaluate their significance and correlate ECG changes with clinical outcomes.

Authors' conflicts of interest in Nepalese healthcare journals.

Most biomedical journals now require authors to declare their conflicts of interest (COI), especially financial ones, before they accept the manuscript for submission. This study aims to examine the COI policies of Nepalese healthcare journals. The sample constituted journals indexed in Nepal Journals Online (NepJOL) as of June 2021. Of the 68 that met our inclusion criteria, 38(55.9%) journals endorsed the COI policy of the International Committee of Medical Journal Editors. Thirty-six (52.9%) journals had a policy for reporting the COI. Financial COI was the only type of COI mentioned. All journals in Nepal are encouraged to request the authors to declare the COI for better transparency.

Clinical Characteristics and Outcome of Patients with Multiple Intracranial Aneurysms from a University Hospital in Nepal.

Objective The risk factors, management strategies, and outcomes of patients with multiple intracranial aneurysms (MIAs) are different compared with that of patients with a single aneurysm. Data are scarce regarding patients with MIAs from developing countries. The objective of this study was to describe the clinical characteristics, management strategies, and outcomes of patients treated microsurgically from Nepal. Methods The clinical records of patients confirmed to have MIAs and microsurgically clipped between July 2014 and December 2019 were retrospectively reviewed. Data on demographic and clinical characteristics, computed tomography findings, multiplicity and location of aneurysms, management strategies, and the 1-year outcome were abstracted and analyzed. Results Two hundred cerebral aneurysms were microsurgically clipped in 170 consecutive patients during the study period. Twenty-six (13.0%) patients harbored 60 aneurysms. The mean age of the patients was 58.5 (43-73) years. Smoking and hypertension were found in 20 (76.9%) and 16 (61.5%) patients, respectively. The majority of patients [17 (65.4%)] were in good grades at presentation. Twenty-one patients had two aneurysms, four had three aneurysms, and one patient had five aneurysms. The middle cerebral artery was the commonest (20) followed by distal anterior cerebral artery (14) and anterior communicating artery (13) involved in multiplicity. A single-stage surgery was performed on 17 patients. Serial clipping was performed in six patients. In three patients, a single aneurysm on the contralateral side was left untreated for various reasons. The favorable outcome was achieved in 23 (88.5%) patients whereas three (11.5%) patients had an unfavorable outcome. One patient died. Conclusion The demographic and clinical characteristics of patients in our series are comparable with those described in the published literature from other countries. With an individualized treatment strategy, an acceptable outcome can be achieved in the majority of the patients.

Marshall Computed Tomography Scoring System in Predicting Early Mortality in Patients with Traumatic Brain Injury.

BACKGROUND: Traumatic brain injury is common neurological emergency worldwide associated with high rates of morbidity and mortality. Marshall scoring system is one of the several scoring systems that uses initial computed tomography findings to predict outcome. This study aims to determine the role of Marshall scoring system in predicting early mortality in patients with Traumatic brain injury in Nepalese patient population. METHODS: Patients admitted with diagnosis of Traumatic brain injury between August 2017 and July 2018 in our institution were studied prospectively. Clinical status of patient was noted and computed tomography scan of head was interpreted according to Marshall scoring system. Patients were monitored during the hospital stay and in-hospital mortality was correlated with different components of Marshall scoring system at discharge. RESULTS: The most common cause of Traumatic brain injury was road traffic accident (45%). Severe Traumatic brain injury was noted in 17% of patients and commonest intracranial mass lesion was contusion (24%). Surgery was performed in 29% of patients. There was significant correlation between increase in Marshall score and mortality (p<0.001). Degree of midline shift (p<0.016), status of basal cisterns (p<0.001), and combination of mass lesions (p=0.005) were independent predictors of early mortality. CONCLUSIONS: Marshall scoring is highly reliable scoring system to predict early mortality in patients with Traumatic brain injury. Degree of midline shift, status of basal cisterns, and combination of mass lesions are independent parameters predicting early mortality in patients with traumatic brain injury.

Cerebral astroblastoma radiologically mimicking pilocytic astrocytoma: A case report.

Astroblastoma is a rare central nervous system tumor. We reported a case of a 24-year-old Nepalese woman with radiological features mimicking pilocytic astrocytoma which came out to be low-grade astroblastoma in histopathological and immunohistochemistry examination after total excision of the tumor.

Post-traumatic Pseudoaneurysm of the Internal Carotid Artery with Intractable Epistaxis: A Case Report.

Epistaxis is a common otorhinolaryngology emergency. There are several treatment modalities for epistaxis, but bleeding from the internal carotid artery necessitates a particular treatment technique. We report a case of a 22-years old man who presented to us recurrent episodes of epistaxis and blurry vision in the right eye for one month. The patient had undergone maxillo-facial surgery following a road traffic accident one year back. Bleeding episodes were occasionally severe with blood loss of up to 800 to 1000ml. These episodes were managed conservatively with posterior nasal packing and frequent blood transfusions. A computed tomography-angiography revealed a pseudoaneurysm arising from the cavernous segment of the right internal carotid artery which was managed successfully by embolization of the aneurysm sac with coils. Despite the rarity of internal carotid artery pseudoaneurysm in individuals with a history of trauma, doctors must be aware of the possibility. Timely identification and treatment of a pseudoaneurysm can save a person's life.

A case report of aneurysmal subarachnoid hemorrhage in a Young with IgA: A mere co-existence?

INTRODUCTION AND IMPORTANCE: Aneurysmal Subarachnoid hemorrhage (SAH) can be associated with various other conditions like Polycystic kidney disease, Ehler Danlos syndrome, Co-arctation of the aorta, etc. CASE PRESENTATION: Here we have reported a 21-year young lady with IgA nephropathy and aneurysmal SAH managed successfully. CLINICAL FINDINGS AND INVESTIGATIONS: The patient was a known case of IgA nephropathy diagnosed 18 months back from a kidney biopsy. She came to the emergency with a headache and vomiting for 2 weeks. Her initial headache was the worst she has had experienced and then the headache was continuous and not relieved by medications. Then she underwent a noncontrast CT scan of the head which showed Subarachnoid hemorrhage (SAH). INTERVENTIONS AND OUTCOMES: Left pterional craniotomy and microsurgical clipping of left ICA aneurysm performed. The patient was discharged without deficits. RELEVANCE AND IMPACT: Aneurysmal Subarachnoid hemorrhage(SAH) can be due to histopathological changes to the vessels following IgA nephropathy. These correlations could be studied further or else it could be only a mere coincidence.

Pituitary Apoplexy Complicated by Cerebral Infarction: A Case Report.

Cerebral infarction is a rare complication of pituitary apoplexy, which can result in significant morbidity if not treated on time. Pituitary apoplexy mostly occurs in pre-existing adenoma, which can remain undiagnosed until symptoms arise. Here, we present a case of a 26-year-old man with undiagnosed acromegaly who presented with left retro-orbital pain, diminished vision of the left eye, and right hemiparesis. Neuroimaging revealed large hemorrhagic sellar mass and ischemic infarction in the left middle cerebral artery territory. Emergency transcranial tumor excision was done, which resulted in significant neurological recovery.

Rebleeding in aneurysm after rectal enema: Re-emphasis on careful subarachnoid hemorrhage management.

Rebleeding in an aneurysmal subarachnoid hemorrhage (SAH) is catastrophic with high mortality and grave outcome. Meticulous management of SAH patients and the prevention of activities that might increase the chances of rebleeding are life-saving.

Temporal Delay in Neurosurgical Patients and Outcome in a Tertiary Care Center in Nepal.

BACKGROUND: Neurosurgery is a field where time from the incident to get treatment is very crucial. In low-income countries, the referral system is not well developed. In our country, a proper referral system is in the initial phase of development. We conducted a study assessing the number of visits a neurosurgery patient made before finally reaching to our center. METHODS: This is a prospective observational study involving seventy patients, conducted at Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Demographic characteristics, neurological diagnosis, and numbers of other centers the patients visited and outcome at discharge and in one month was assessed. RESULTS: Thirty-five (50%) patients were males. Thirty-three (47.1%) patients were admitted due to head injury and 13 (18.5%) were diagnosed with subarachnoid hemorrhage. Surgery was done in 32 (45.7%) patients. Fifty-three (75.7%) patients were transferred from other hospitals. Out of 53 patients, 30 (56.6%) and 17 (32%) had visited to one and two hospitals respectively. Unavailability of the neurosurgery facility was the main reason (77.4%) for the transfer. Overall mortality was 12.9%. The trend for mortality and length of hospital stay was higher in the group who visited other centers before coming to us than those who came directly. CONCLUSIONS: Visiting multiple hospitals where there is no neurosurgical service available is an important reason for delay. There is a need to develop neurosurgical facilities in the different parts of the country along with establishment of an effective referral mechanism.

Successful Treatment of Giant Intracranial Aneurysm Using Flow-Diverter Device: First Experience in Nepal.

Giant intracranial aneurysms are defined as aneurysms that measure over 25 mm in the greatest dimension. They are rare vascular lesions that preferentially involve regions with high-velocity blood flow, such as the cavernous and supraclinoid segments of the internal carotid artery, the middle cerebral artery, the vertebrobasilar region, and the basilar apex. The treatment of giant aneurysms is challenging and associated with high rates of morbidity and mortality. Flow-diverter devices have revolutionized their treatment in recent times. We report the successful management of two patients with giant cavernous internal carotid artery aneurysms using flow-diverter devices for the first time in Nepal. Keywords: Endovascular; flow-diverter devices; giant aneurysm.

Remote Supratentorial Subdural Hematoma Following Craniectomy and Evacuation of Hypertensive Cerebellar Hematoma.

Remote acute subdural hematoma following a decompressive craniotomy or craniectomy is a rare phenomenon. Only few cases of postoperative contralateral acute subdural hematomas have been reported in the literature review till date. This case report details a case of a 32-year-old hypertensive male who presented with severe headache, multiple episodes of vomiting, slurring of speech, nystagmus and ataxic gait for one day. Computed tomography (CT) scan of head revealed a right sided cerebellar hemorrhage with effacement of fourth ventricle and upstream hydrocephalus. A right suboccipital craniectomy and hematoma evacuation were performed. A repeat CT scan of head was done at six hours post surgery; which revealed a contralateral (left-sided) subdural hematoma involving the fronto-parieto-temporal region. The patient improved following conservative management. Contralateral acute subdural hematoma following evacuation of hematoma is a rare, but a potentially life-threatening complication; therefore, we should try to detect such contralateral hematoma and prevent clinical deterioration.

Calvarial Tuberculosis: A Diagnostic Quandary: A Case Report.

Primary Calvarial Tuberculosis, a rare entity of skull is even rarer after second decade of life in a healthy person without evidence of tuberculosis elsewhere in the body. Most of the cases are often misdiagnosed as osteomyelitis/syphilis/bony metastasis. We report a case of primary skull tuberculosis in 26-year-old male with complains of headache and swelling in the right frontal region with no history of previous tuberculosis. The patient was operated and the histopathological examination of excised tissue was suggestive of tubercular pathology. The patient is doing well after anti-tubercular therapy. Being a rare disease, tubercular osteomyelitis of skull bones is often missed and misdiagnosed due to lack of clinical suspicion and slow growth of mycobacterium cultures. Histopathological examination of biopsy material and demonstration of acid-fast bacilli in the pus are helpful for diagnosis and early management of the disease. Keywords: calvaria; Mycobacterium; osteomyelitis; tuberculosis.

Cerebral venous thrombosis presenting with intracerebral hemorrhage in a patient with paroxysmal nocturnal hemoglobinuria.

Cerebral venous thrombosis (CVT) is an uncommon cause of stroke. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare type of hemolytic anemia, frequently associated with thrombophilia. PNH may rarely present with CVT. Approximately, one-third of the patients with CVT develop cerebral hemorrhage. Here, we present a rare combination of CVT presenting with intracerebral hemorrhage in a patient with PNH. High index of suspicion is needed to avoid misdiagnosis. Patient was successfully managed with anticoagulation therapy.
