Aneurysms of any part of the extracranial carotid artery are uncommon lesions [1-6], and those involving just the common carotid segment may appropriately be considered rare. Although fusiform enlargement of the mediastinal segment of the left common carotid artery can occur in atherosclerotic disease and in association with syphilitic and other forms of aortitis, a saccular form of aneurysm in...

The aim of this study was to identify the main factor affecting compliance and intima-media thickness of the elastic common carotid artery in continuous ambulatory peritoneal dialysis patients. Increased intima-media thickness and decreased arterial compliance are associated with elevated risk of cardiovascular disease. This study included 20 patients and 20 age- and sex- matched healthy contro...

background sphenoid sinus is surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...

A 63-year-old man, who was on follow-up for squamous cell carcinoma of thebase of the tongue status postradiation therapy 3 years prior, presented for color Doppler examination of the neck vessels. He was asymptomatic for neurologic deficits and was being treated for radiation-induced hypothyroidism and xerostomia. Clinical examination revealed no neck masses or nodes. Chest radiograph revealed...

Animal models are essential for understanding the pathology of stroke and investigating potential treatments. However, in vivo stroke models are associated, particularly in mice, with high variability in lesion volume. We investigated whether a surgical refinement where reperfusion is not reliant on the Circle of Willis reduced outcome variability. Mice underwent 60 min of transient middle cere...

Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
