Tumor-induced rotational vertebral artery occlusion in the upper cervical spine: illustrative case.

Background: Rotational vertebral artery occlusion, or bow hunter's syndrome (BHS), is a rare but clinically important cause of vertebrobasilar insufficiency. Extrinsic compression of the artery is usually caused by osteophytes, fibrous bands, or lateral disc herniation and typically occurs in the setting of anatomical variations, leading to dynamic compromise of the posterior circulation. Neoplastic causes of BHS are rare.

Transcarotid arterial revascularization for symptomatic carotid web.

Objectives: Symptomatic carotid web is an increasingly recognized cause of acute ischemic stroke with a high risk of recurrent ischemic events despite aggressive medical interventions. Surgical interventions including transfemoral carotid artery stenting (TFCAS) and carotid endarterectomy have been described to reduce this risk, but transcarotid arterial revascularization (TCAR) has not been evaluated for this purpose.

Materials And Methods: Patients with cerebral ischemia from carotid web underwent TCAR with flow reversal.

In-hospital recurrent stroke in ipsilateral carotid web patients undergoing thrombectomy.

Objective: Carotid artery web is a possible cause of ischemic stroke, especially in young patients who lack conventional risk factors. The immediate and long-term outcomes are not well studied. We aimed to determine the association between an ipsilateral carotid web and in-hospital stroke recurrence.

Population analysis of ischemic stroke burden and risk factors in the United States in the pre- and post-mechanical thrombectomy eras.

Objectives: To provide an updated analysis of the burden of ischemic stroke in the United States.

Materials And Methods: Using the Global Burden of Disease database, we estimated age-standardized, population-adjusted rates of incidence, prevalence, mortality, and disability-adjusted life years from 2010 to 2019, with regional comparisons. Deaths and disability-adjusted life years were compared in 2010-2014 and 2015-2019 to assess the potential effect of increased mechanical thrombectomy use.

Minimizing blood loss with direct percutaneous polymethylmethacrylate embolization before corpectomy for vascular spinal tumors.

Background: Standard surgical treatment for vascular spinal tumors, including renal cell carcinomas and hemangiomas, may result in significant blood loss despite preoperative arterial tumor embolization.

Methods: This is a retrospective review of 12 patients who underwent direct percutaneous polymethylmethacrylate embolization (DPPE) with or without feeding artery embolization before partial or complete corpectomy for the resection of vascular spinal tumors (2013-2018). Estimated blood loss (EBL) was compared to the blood loss reported in the literature and to patients receiving standard arterial embolization before surgery.
