Brainstem auditory evoked potentials (BAEPs) have been used as a valuable neurophysiologic index of neuronal dysfunction in the level of the brainstem. BAEPs are also useful in subdividing evoked potentials into normal, slight, or pronounced in patients with vertebrobasilar insufficiency. We investigated the changes of BAEP after vertebrobasilar artery ischemia ...

Intravascular treatment of cavernous dural arteriovenous fistula (dAVF) is usually safe and effective. However, we describe a patient with a rare brainstem hemorrhage during transvenous embolization (TVE). A 79-year-old woman suffered from left chemosis and diplopia. Cerebral angiography revealed a left cavernous dAVF with cortical venous drainage. The patient underwent ...

Background: Atherosclerosis is a systemic disease. Many ischemic stroke patients may have concomitant coronary artery disease (CAD). Detection and treatment of preclinical CAD in stroke patients may improve long-term outcome and survival because CAD is a major cause of death during follow-up in stroke patients. However, association between coronary and ...

Stroke in trisomy 21 may be due to cardioembolism, atherosclerosis, vasculitis, moyamoya disease, sinus venous thrombosis, internal carotid hypoplasia or infections like endocarditis with septic emboli, meningitis or brain abscess. In rare cases, however, stroke etiology remains unexplained. We present a 19 year old Caucasian girl with trisomy 21 with ...

Semilunar valve malformations are common human congenital heart defects. Bicuspid aortic valves occur in 2-3% of the population, and pulmonic valve stenosis constitutes 10% of all congenital heart disease in adults (Brickner et al., 2000) [1]. Semilunar valve defects cause valve regurgitation, stenosis, or calcification, leading to endocarditis or congestive ...

OBJECTIVES: The objective of this study was to compare the cerebral embolic load of filter-protected versus proximal balloon-protected carotid artery stenting (CAS). BACKGROUND: Randomized trials comparing filter-protected CAS with carotid endarterectomy revealed a higher periprocedural stroke rate after CAS. Proximal balloon occlusion may be more effective in preventing cerebral embolization ...

Carotid-to-radial pulse wave velocity (PWV(cr)) has been proposed to evaluate endothelial function. However, the measurement of PWV(cr) is not without limitations. A new simple approach could have wide application. Stiffness index (SI) is obtained by analysis of the peripheral pulse wave and gives reproducible information about stiffness of large arteries. ...

ABSTRACT: Closed-chest totally endoscopic coronary artery bypass grafting (TECAB) is feasible using robotic technology. During the early phases, TECAB was restricted to single bypass grafts to the left anterior descending artery system. Because most patients referred for coronary artery bypass surgery have multivessel disease, development of endoscopic multiple bypass grafting ...
