The natural history of unruptured dissections of the intracranial vertebral artery (VA) is not well delineated. The dissected VA may heal spontaneously or may be associated with ischemic events. ⋯ The authors present a challenging case of bilateral VA dissections associated with left VA pseudoaneurysm that was initially managed medically.1-3 Imaging follow-up demonstrated rapid progression with flow-limiting dissection and increase in pseudoaneurysm size. The decision making of the case and procedural nuances are discussed in this video case report (Video 1).

Treatment of unruptured intracranial arteriovenous malformations (AVMs) has become controversial since the ARUBA (A Randomized Trial of Unruptured Brain Arteriovenous Malformations) study was published in 2014. We sought to analyze changes in the demographics, clinical presentation, and treatment strategies in 2 patient cohorts from the same institution separated by 40 years. ⋯ Compared to 40 years ago, more patients are presenting with incidentally discovered intracranial AVMs and are undergoing interventional treatment. Better understanding of the natural history, developments in endovascular therapy, and stereotactic radiosurgery, as well as improvements in microsurgical techniques have led to a substantial increase in patients undergoing invasive treatment.

The analysis of perioperative electronic patient portal (EPP) communication may provide risk stratification and insight for complication prevention in patients with affective disorders (ADs). We aimed to understand how patterns of EPP communication in patients with AD relate to preoperative narcotic use, surgical outcomes, and readmission rates. ⋯ AD patients have specific patterns of perioperative EPP communication. They are at a higher risk of postoperative complications. Addressing these concerns early may prevent more serious morbidity and avoid unnecessary ED visits and readmissions, thus reducing costs and improving patient care.

Updates in Chronic Subdural Hematoma: Epidemiology, Etiology, Pathogenesis, Treatment and Outcome.
Chronic subdural hematoma (CSDH) is a complex disease with an overall incidence of 1.7-20.6 per 100,000 persons per year and is more commonly encountered in the elderly population. The pathophysiologic cycle of CSDH formation and expansion involves traumatic and inflammatory components that promote the formation of membranes with permeable neovessels. ⋯ Recurrence can occur in 10%-20% of patients and is associated with several clinical and radiographic predictors. Middle meningeal artery embolization represents one of the latest additions to the therapeutic arsenal of cerebrovascular specialists in treating CSDH and is being critically evaluated in numerous ongoing clinical trials.

Pharyngoesophageal injury during anterior cervical spine surgery is a rare and potentially life-threatening complication; generally it is the result of intraoperative manipulation or hardware erosion and sometimes may be due to weakness of the pharyngoesophageal wall from pre-existing pathologic conditions, such as diabetes, gastritis, or obesity. ⋯ Appropriate treatment for pharyngoesophageal perforations is controversial and not investigated in detail. There is a lack of prospective studies comparing initial conservative versus surgical approaches to treatment. In addition, endoscopic management is growing as a therapeutic option, but no consensus concerning the indications for an endoscopic approach in the treatment of pharyngoesophageal injury in anterior cervical spine surgery is currently reached. A common theme proposed in the literature is that early recognition and aggressive investigation and treatment are essential to ensure a good outcome. A customized interdisciplinary surgical approach is essential for successful treatment. Use of the transoral endoscopic approach is a useful noninvasive method to treat this rare but potentially devastating complication.
