This review focuses on the often-neglected long-term neuropsychiatric consequences of aneurysmal subarachnoid hemorrhage (aSAH), beyond traditional randomized trial outcomes of mortality and retreatment. While current guidelines recommend screening for these sequalae, it may not be routinely practiced. This review will underscore the prevalence and management of common neuropsychiatric sequalae, including anxiety, depression, cognitive dysfunction, headaches, seizures, and sexual dysfunction, all of which can significantly impact the quality of life of survivors of aSAH...

[Expert consensus on multidisciplinary diagnosis and treatment of brain arteriovenous malformation].
(no author information available yet)
Brain arteriovenous malformation (BAVM) is a cerebral vasculature disorder caused by gene mutation. Current available treatment measures include surgical resection, interventional embolization and stereotactic radiosurgery. The three therapeutic methods have their own advantages for different vascular structures.However, due to the complex vascular architecture of the lesion and its close anatomical relationship with brain tissue, any single treatment can not safely and effectively treat all BAVM cases. Therefore, in order to better regulate and guide the clinical diagnosis and treatment of BAVM patients in China, the National Medical School for Neurological Diseases, the Professional Committee of Neurointervention of the Chinese Medical Doctor Association and the radio-neurosurgery Expert Committee of the World Chinese Neurosurgeons Association jointly discussed and formulated this expert consensus...

OBJECTIVE: Treatment of intracranial aneurysms by flow diversion is safe and effective and is increasingly popular. However, the correct treatment paradigm for aneurysms incompletely treated by initial placement of a flow diverter has not been established, nor have the subsequent natural history and occlusion rates of such aneurysms. The authors sought to outline the natural history of such aneurysms, which to date have been considered partially treated. METHODS: The authors retrospectively reviewed consecutive cases from 6 high-volume neurointerventional services, including all cases in which the first follow-up imaging after placement of a flow diverter showed incomplete occlusion of the aneurysm, and for which subsequent clinical and/or radiological follow-up was available...

INTRODUCTION: The internet is an essential resource for patients and their loved ones to understand their medical conditions, and professional medical organizations have taken great strides to develop educational material targeting patients. The average American reads at a seventh to eighth grade reading level, hence it is important to understand the readability of this medical information to ensure patients comprehend what is being presented. METHODS: In January 2023, online patient education material was downloaded from major cerebrovascular healthcare organizations and assessed using eight assessments, including Bormuth Cloze Mean, Bormuth Grade Placement, Coleman-Liau (grade levels), Coleman-Liau (predictive cloze scores), Flesch Reading Ease (FRE), and Fry...

Carotid-Cavernous sinus fistula (CCF) represents a misdiagnosed condition with potential repercussion in functional, neurological, and social roles of patients with this disease. Earlier reports remark on the efficiency and safety of endovascular therapy with resolution of the symptoms were performed appropriately. We present a case of a male patient from a developing country, with gunshot wound head trauma history and short-term progressive functional and neurological impairment in the presence of intracranial hypertension and ocular symptoms who developed a large CFF, subsequently treated by transradial access embolization...

We report a case of a patient who initially presented with a subarachnoid haemorrhage secondary to a ruptured supraclinoid internal carotid artery (ICA) blister aneurysm. The patient was treated successfully with a flow diverter stent (FD) and coiling; however, a large aneurysm recurrence via a feeding posterior communicating artery (PCOM) was noted on the 1-year follow-up angiogram. During the retreatment, a second FD in the ICA resulted in insufficient aneurysm stasis. Therefore, the decision was made to coil sacrifice the PCOM via posterior circulation access...

BACKGROUND: Arteriovenous shunt below the conus medullaris (AVS-BC) is easily misdiagnosed and mistreated due to its rarity. Achieving an anatomical cure solely through endovascular or surgical means is challenging. This study aimed to summarize the clinical and radiological features of AVS-BC and evaluate the safety and efficacy of hybrid techniques represented by intraoperative direct venous puncture and embolization (IVPE). METHODS: The patients with AVS-BC were grouped into those with dural, intradural, and paravertebral shunts...

BACKGROUND: Liquid embolic agents (LEAs) such as ethylene vinyl alcohol (EVOH) are utilized for middle meningeal artery embolization (MMAE) for chronic subdural hematomas (cSDH). LEAs may be advantageous for MMAE as they are permanent and can penetrate the microvasculature of the subdural membranes. LEA surface area (SA) can quantify this penetration. The segmentation of LEA SA is not described in the literature and may be of interest in refining MMAE technique. METHODS: We retrospectively collected computerized tomography (CT) scans from 74 patients (with 95 cSDH) who underwent first-line MMAE with EVOH...

A man in his late 60s presented with intermittent abdominal pain, nausea, vomiting and approximately 40 pounds of weight loss over the course of a year, most concerning for chronic mesenteric ischaemia. Given a prior negative workup, a CT angiogram was performed and revealed a wide neck mid-superior mesenteric artery pseudoaneurysm (PSA). As PSAs are susceptible to thrombus formation and distal emboli, this incidental finding was considered a possible explanation for his intermittent symptoms and thus required treatment...

BACKGROUND: The absence of the susceptibility vessel sign (SVS) in patients treated with mechanical thrombectomy (MT) is associated with poor radiological and clinical outcomes after 3 months. Underlying conditions, such as cancer, are assumed to influence SVS status and could potentially impact the long-term outcome. We aimed to assess SVS status as an independent predictor of long-term outcomes in MT-treated patients. METHODS: SVS status was retrospectively determined in consecutive MT-treated patients at a comprehensive stroke center between 2010 and 2018...
