An intrasaccular flow diverter, the Woven EndoBridge device has emerged as an alternate intervention for complex aneurysms of the ACA, MCA, ICA, and basilar artery. However, few studies report the use of the WEB device in off-label locations. This case report aims to contribute to this limited collection of data. We present a case of a 53-year-old male presenting with occipital headaches, found to have vertebrobasilar junction aneurysm. The WEB device was successfully used to embolize a large aneurysm of the vertebrobasilar junction, a current off-label location. This represents a new use of the WEB device, as well as an approach that addresses the limitations of other techniques used for vertebrobasilar junction aneurysms.

Objective

Craniocervical junction arteriovenous fistula (CCJ-AVF) is a rare disease, and preoperative imaging evaluation is important in developing treatment strategies due to the complexity of the vascular architecture, such as the feeding vessels, shunt points, and draining veins. In the present study, we report a case of hemorrhagic perimedullary CCJ-AVF with multiple feeding vessels in which the common single draining vein was dissected by craniotomy and completely treated.

Case presentation

A 71-year-old woman presented with subarachnoid hemorrhage (Hunt & Kosnik, grade II). Cerebrovascular CTA showed no intracranial cerebral aneurysm and findings suggestive of shunt disease at the CCJ. Based on cerebral angiography, the patient was diagnosed with perimedullary CCJ AVF, with the right radicular and the left anterior spinal arteries as feeders which drain into a common dilated coronary vein through a shunt located on the ventral side of the spinal cord and then drain into the ascending and descending anterior spinal veins. Ventricular drainage was performed for acute hydrocephalus, and arteriovenous fistula was dissected electively by craniotomy on day 17 after onset. A clip was applied to the single draining vein, which had been evaluated using preoperative imaging diagnosis. Intraoperative digital subtraction angiography (DSA) confirmed the disappearance of shunt blood flow, and the surgery was completed. The follow-up DSA did not show shunt blood flow, and the patient was transferred to a rehabilitation hospital with a modified Rankin scale score of 2.

Conclusion

CCJ-AVF cases often have a complex vascular architecture, and it is important to use various modalities to understand the vascular anatomy in detail and develop an appropriate treatment strategy.

A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first identified in December 2019 in Wuhan, China. The new coronavirus disease (COVID-19) was declared a global pandemic by the World Health Organization (WHO) in March 2020. SARS-CoV-2 can invade the nervous system aside from infecting the respiratory system as its primary target. The most common nervous system symptoms of COVID-19 are stated as headache, myalgia, fatigue, nausea, vomiting, sudden and unexplained anosmia, and ageusia. More severe conditions such as encephalomyelitis, acute myelitis, thromboembolic events, ischemic stroke, intracerebral hemorrhage, Guillain-Barré-syndrome, Bell's palsy, rhabdomyolysis, and even coma have also been reported. Cohort studies revealed that neurological findings are associated with higher morbidity and mortality. The neurological symptoms and manifestations caused by SARS-CoV-2 and COVID-19 are examined and summarized in this article.

Pituitary apoplexy often manifests with a severe headache and is often caused by bleeding in a pituitary adenoma, which is common and often undiagnosed. The pituitary gland is damaged when the tumour suddenly enlarges due to bleeding. Bleeding into the pituitary can block blood supply to the pituitary gland. The larger the tumour, the higher the risk of a future pituitary apoplexy. Since only few cases have been reported, the SARS-CoV-2 vaccine is unlikely to cause pituitary apoplexy. Patients with new-type headache require neurological evaluation and may require cerebral imaging to rule out bleeding, ischemia, venous sinus thrombosis, meningitis, encephalitis, pituitary apoplexy, reversible cerebral vasoconstriction syndrome, dissection, or migraine.

It is news of 28 October 2022 that the Pharmacovigilance Risk Assessment Committee of the European Medicines Agency has recommended to add heavy menstrual bleeding among the side effects of unknown frequency inside the package insert of nucleoside-modified messenger ribonucleic acid vaccines to prevent coronavirus disease 2019 (COVID-19). The decision has been made in the light of the numerous reports of unexpected menstrual changes or abnormal uterine bleeding following COVID-19 vaccination. Here we advance a possible involvement of the particular adenohypophyseal microcirculation in these strange and still unexplained events.

Cerebrovascular events are increasingly recognized as a complication of SARS-CoV-2 infections. They can be due to hypercoagulability, vasculopathy, cardiac involvement in the infection, or autonomic dysfunction. However, establishing a causal relationship between cerebrovascular events and viral infection is not always easy and requires thorough investigation and documentation of a close temporal relationship between SARS-CoV-2 infection and the onset of cerebral impairment. Establishing a causal relationship between SARS-CoV-2 infection and cerebrovascular events is desirable as it can guide therapeutic management and determine the outcome.

Background

Cognitive impairments, pain, and motor dysfunction are daunting challenges for stroke survivors, clinicians, and caregivers during rehabilitation programmes. There is a dearth of studies investigating the effectiveness of combining neurodevelopmental technique telerehabilitation-based exercises with transcranial direct current stimulation (tDCS) for stroke survivors with mild cognitive impairments post-stroke.

Objectives

The primary aim of this study is to investigate and compare the effects of Telerehabilitation-Based Exercises with or without Transcranial Direct Current Stimulation (tDCS) on pain, motor and cognitive function in older adults with mild cognitive impairments post-stroke.

Methods

A multi-arm parallel-group (three groups) randomized controlled trial study involving a minimum of 87 participants (29 per group) will be conducted. Participants will be randomized into either telerehabilitation programmes with tDCS, telerehabilitation programmes alone or conventional physiotherapy programmes. All participants will be treated 3 times weekly for 8 weeks (45 min of intervention per session).

Discussion

The findings in this study are expected to guide the provision of effective and affordable rehabilitation for stroke survivors with mild cognitive impairment.

Stroke, a cerebrovascular disease with a high mortality rate, is categorized as either ischemic or hemorrhagic. Current existing therapies have limitations, including a narrow time window for treatment. As stroke induces a rapid and large immune response, immune cells and inflammatory mediators have become promising therapeutic targets for both ischemic and hemorrhagic strokes. In recent years, T cells have been investigated for their role in the pathogenesis of secondary injury and their therapeutic potential after stroke. And regulatory T cells, as one of the subpopulations of T cells, have been proved neuroprotective at both acute and recovery stages. In this review, we summarize the existing roles of Tregs in stroke and the various methods available for Treg intervention, and then provide a perspective for the future of immunotherapy in stroke.

Objective

Hematoma expansion is associated with unfavourable neurological outcomes in intracranial haemorrhage. We aimed to study association of red blood cell (RBC) indices, platelet indices, and their ratios with hematoma expansion, detected by serial computed tomography (CT).

Methods

Hospital-based observational study of 88 patients with intracerebral hematoma referred for serial CT head with patients grouped as having progression/ no change/ resolution of hematoma. Baseline hematological indices and ratios were analysed.

Results

40 patients (45.5 %) had resolution, 20 patients (22.7 %) had no change and 28 patients (31.8 %) had progression of hematoma. RBC distribution width (RDW) (p value 0.001) and Plateletcrit (p-value 0.009) showed statistically significant difference among the groups. RBC distribution width (RDW) to PC ratio (RPR) showed statistically significant increase (p < 0.001) in patients with progression. Receiver operating characteristic curve with RPR as test variable in predicting progression of hematoma showed cut-off value as 0.0615 (64.3 % sensitivity, 63.3 % specificity). Patients with RPR > 0.0615 had greater chances of hematoma progression {OR 3.1 (95 % CI 1.22 to 7.91); p = 0.0174}

Conclusion

Raised RPR was most significant parameter with higher RDW, lower plateletcrit values in patients with progression of intra-parenchymal hematoma. These readily available indices can aid in prompt prognostication of intracerebral haemorrhage cases.
