INTRODUCTION Combined endovascular interventions on carotid and coronary arteries are rare. Stenting of the unprotected coronary left main stem is a high risk procedure. We presented hemodynamically unstable patient with combined carotid artery and left main stem coronary artery stenting. CASE REPORT A 78-year-old female patient was admitted to our institution for right carotid endaterectomy....

OBJECTIVE Mural inflammation has been shown to contribute to the development of plaque, with the α(V)β(3) integrin highly expressed in atherosclerotic plaques. We herein examined α(V)β(3) integrin expression as a function of carotid atherosclerosis formation in the apolipoprotein E-deficient (apoE(-/-)) mouse. METHODS AND RESULTS Constrictive collars were placed around the left common carotid...

BACKGROUND AND PURPOSE Spontaneous vasospasms of the submandibular internal carotid arteries are rarely observed. They are a highly dynamic process, recur frequently, and can be detected by serial ultrasound examinations. SUMMARY OF CASES We present 2 cases of recurrent extracranial vasospasms of the internal carotid artery as a cause of stroke. In both cases, arterial dissection was initiall...

Background and Purpose—Spontaneous vasospasms of the submandibular internal carotid arteries are rarely observed. They are a highly dynamic process, recur frequently, and can be detected by serial ultrasound examinations. Summary of Cases—We present 2 cases of recurrent extracranial vasospasms of the internal carotid artery as a cause of stroke. In both cases, arterial dissection was initially ...

Introduction. Histologic changes which occur in the tunica adventitia during initiation, progression, and complications of atherosclerosis are seldom reported. This study aimed at describing the features of atherosclerosis in the tunica adventitia of two of the commonly afflicted arteries, namely, left anterior descending coronary and common carotid in black Kenyans. Materials and Methods. Spec...

• Vol 7 • November 2005 Velocardiofacial Syndrome A 19 month old baby presented with gradually developing respiratory distress and stridor. Episodes of cyanosis during feeding started immediately after birth, accompanied by a weak cry. Fiberoptic pharyngolaryngoscopic examination revealed prominent pulsations along the posterior pharyngeal wall, and severe subglottic stenosis. Computed tomograp...

Background Multilevel significant atherosclerotic disease involving the carotid bifurcation and the proximal ipsilateral common carotid or brachiocephalic arteries presents an uncommon and difficult management problem. Axial (aortocarotid bypass) or extra-anatomic procedures (subclavian–carotid bypass, carotid–carotid bypass, carotid–subclavian transposition) and variations in the performance o...

BACKGROUND AND PURPOSE We examined the associations of parental longevity with carotid intima-media thickness, carotid plaques, and aortic arterial stiffness in adult offspring. METHODS A population of 1117 volunteers who participated in the SUVIMAX Vascular Study (mean age, 59.7 years; 49.0% women) were included. Carotid-femoral pulse-wave velocity (PWV) was used to assess aortic stiffness. ...

Increases in arterial carbon dioxide tension (hypercapnia) elicit potent vasodilation of cerebral arterioles. Recent studies have also reported vasodilation of the internal carotid artery during hypercapnia, but the mechanism(s) mediating this extracranial vasoreactivity are unknown. Hypercapnia increases carotid shear stress, a known stimulus to vasodilation in other conduit arteries. To explo...

The cardiac cycle imposes a mechanical stress that dilates elastic carotid arteries, while shear stress largely contributes to the endothelium-dependent dilation of downstream cerebral arteries. In the presence of dyslipidemia, carotid arteries stiffen while the endothelial function declines. We reasoned that stiffening of carotid arteries would be prevented by reducing resting heart rate (HR),...
