carotid body tumors (cbts) are rare, slow-growing tumors that should be considered in evaluating every lateral neck mass. this single center study was performed to define demographic features, clinical characteristics and remedies of iranian patients with cbt. a retrospective review of prospectively collected data was done on 45 patients with 50 cbts who have been referred to sina hospital, teh...

Extracranial internal carotid artery aneuriysms (EICAA) are rare. There are few reports in the medical literature about its etiology, relating these aneurysms to atherosclerosis, arteritis and alterations due to trauma or after surgical procedure. The natural history of the disease has not been well-defined yet. However, the potential risk of embolism originating from the aneurysm – or even its...

Congenital arteriovenous communications involving the external carotid artery and jugular veins are rare. We report a 4-year-old girl with a history of an abnormal audible sound in the right ear during sleep. Physical examination revealed a carotid bruit, thrill and a pulsatile mass in the right neck. A simple congenital right external carotid-jugular arteriovenous fistula was confirmed and suc...

Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These featur...

Correspondence To the Editor: Carotid body tumor (CBT) is a highly vascular neoplasm of neural crest origin arising in paraganglial cells of the carotid bifurcation. Branches from external carotid artery or glomic artery arising at the bifurcation of common carotid artery dominate in the blood supply mode. Only very few cases with supplementary blood supply from an internal carotid artery (ICA)...

BACKGROUND AND PURPOSE The clinical application of intracranial near-infrared spectroscopy in adults has been hampered by concerns over contamination from extracranial tissues. The NIRO 300 (Hamamatsu Photonics) provides continuous online measurements of hemoglobin and cytochrome oxidase concentrations and a calculated tissue oxygen index (TOI). The present study seeks confirmation of the anato...

Skin temperatures were recorded from the medial upper orbital area and above the nasal, mid and lateral portions of the brows in normal subjects and in patients with suspected cerebrovascular disease. Temperatures were reduced across the brow in patients with external carotid artery disease. Temperatures were lower than normal in the orbit in patients with internal carotid artery disease except...
