Ischemic stroke is more often diagnosed in the left hemisphere than in the right. It is unknown whether this asymmetrical prevalence relates to differences in carotid atherosclerosis. We compared atherosclerotic plaque prevalence, severity, and composition between left and right carotid arteries. In a population-based cohort, carotid MRI scanning was performed ...

Aneurysmal bone cysts (ABC) are benign bone lesions found in children and young adults. Rarely, these lesions can arise from ribs, and there is disagreement on the best treatment because of proximity to vital structures. Frequently, surgeons remove ABC with en bloc resection. Selective arterial embolization has been used as ...

Emerging evidence indicates that plaque imaging can improve stroke risk stratification in patients with carotid artery atherosclerosis. We studied the association between soft and hard (calcified) plaque thickness measurements on CTA and symptomatic disease status (ipsilateral stroke or TIA) in patients with moderate-grade carotid artery stenosis.

Whether carotid artery stenosis predicts stroke after noncardiac surgery remains unknown. We therefore tested the primary hypothesis that degree of carotid artery stenosis is associated with in-hospital stroke or 30-day all-cause mortality after noncardiac surgery. As carotid artery stenosis is also a marker for cardiovascular disease, our secondary hypothesis was ...

Acute aortic dissection is a catastrophic condition, for which emergency surgery is the mainstay of therapy. In approximately 70% of patients who survive surgery, a dissected distal aorta remains, posing a risk of late aneurysmal degeneration, rupture, and malperfusion, and secondary extensive interventions are often required. In order to improve ...

Intra-arterial therapy (IAT) for acute ischemic stroke treatment is evolving. Whereas the efficacy of recanalization with traditional intra-arterial fibrinolysis is relatively poor, mechanically based recanalization with multimodal approaches, stenting and mechanical embolectomy is more effective. Until recently, this has not resulted in overwhelming clinical benefit and has not always equated ...

Coronary atherosclerosis is the pathophysiologic background of coronary artery disease. Vascular calcification is an actively regulated form of calcified tissue metabolism and a common feature of coronary atherosclerotic plaques. Interestingly, systematic research has revealed that vascular mineralization, is also a strong and independent predictor of cardiovascular morbidity and mortality. Recently, ...

Transapical aortic valve replacement through an apical aneurysm is traditionally contraindicated because of the risk of severe systemic embolization when thrombi are present. However, a chronic fibrotic aneurysm without apical thrombi carries a low risk of distal embolization and can be safely employed for a transapical transcatheter aortic valve replacement ...

The increased fetoplacental vascular resistance due to chronic hypoxia cannot be explained by simple hypoxic vasoconstriction, as it sustains to some degree after recovery in normobaric environment. To verify a hypothesis that fetoplacental arteries undergo remodeling of their walls similar to remodeling of pulmonary arteries in hypoxic pulmonary hypertension, we ...
