Vertebral artery ostial stenosis is implicated in one-fifth of all posterior circulation cerebrovascular accidents. However, uniform treatment guidelines and data on the different treatment modalities are still lacking. Endovascular stenting is an emerging therapy for symptomatic vertebral artery ostial stenosis when medical management fails. This manuscript will examine the safety and efficacy of endovascular revascularization with drug-eluting stents in a series of ten consecutive patients that had failed medical management. We also report the rate of complications and in-stent restenosis, as well as the rate of recurrent cerebrovascular accidents.

Percutaneous vertebroplasty (PVP) is a widely utilized minimally invasive technique originally developed for the treatment of vertebral compression fractures. It has since expanded to treat osteoporotic vertebral compression fractures, pathologic vertebral fractures resulting from primary or secondary spinal tumors, and traumatic spinal fractures. Despite its benefits, PVP is associated with significant complications, the most common of which is bone cement leakage.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 days of bed rest.

Cardiac allograft vasculopathy (CAV) remains a significant challenge after heart transplantation, necessitating effective surveillance methods. This review centers around the role of coronary computed tomography angiography (CCTA) in CAV surveillance, given its unique capabilities to visualize and quantify CAV in comparison with other imaging modalities, including invasive coronary angiography and intravascular ultrasound. CCTA has shown good diagnostic performance for detecting and monitoring CAV, exemplified by a higher sensitivity and negative predictive value compared with invasive coronary angiography.
View Article and Find Full Text PDFAberrant anatomical variation of the vertebral artery (VA) from an internal carotid artery (ICA) is considered a rare finding. The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.
