We present a 69-year-old man with advanced vertebral artery atherosclerotic disease and repeated posterior fossa strokes, refractory to aggressive medical treatment. CT angiogram showed heavily calcified long segment occlusion of the dominant right vertebral artery. Beyond the occlusion, the vertebral artery was reconstituted by hypertrophic deep cervical collaterals which had multiple long and short segments of severe stenosis and antegrade flow. The ostium of the right vertebral artery was heavily calcified, and multiple attempts to catheterize the vertebral artery were unsuccessful. Flow reversal was eventually achieved in the right vertebral artery by embolizing the hypertrophied deep cervical artery which reconstituted the right vertebral artery. The patient has remained asymptomatic since the procedure for a follow-up period of 12 months.

Background And Objectives: Three-column osteotomy (3CO) offers substantial spinal deformity correction. Thoracic neurovascular bundle sacrifice is often required, and anterior spinal artery (ASA) perfusion can be compromised. Spinal angiography allows localization of variable ASA vascular contribution.

Background: While acute occlusion of the subclavian artery (SCA) proximal to the vertebral artery (VA) origin is an uncommon but recognized cause of embolic stroke, an occlusion distal to the VA is rare and can be easily overlooked.
Case Description: We describe the clinical presentation and evaluation of a previously healthy 56-year-old woman who experienced four life-threatening posterior circulation strokes within 1 month, three of which led to basilar artery (BA) occlusions requiring thrombectomies. Workup revealed an occlusion of the right SCA located less than 1 cm distal to the VA origin.

Background And Purpose: Dual-energy computed tomography (DECT) pulmonary angiography can reliably detect cement pulmonary embolisms (CPEs) and parenchymal perfusion defects. This prospective observational study investigated CPEs in asymptomatic patients using DECT.
Methods: We enrolled 42 patients who underwent vertebroplasty or received cement screws for vertebral augmentation, examining them using spinal computed tomography and DECT pulmonary angiography.
