Researchers of University of Bristol found that by removing the carotid body connection to the brain in rodents with high blood pressure, blood pressure fell and remained low.
The majority were again carotid body tumors, at 60% of head and neck paragangliomas in this particular series (10).
A 47 years old woman was found to have a carotid body tumor in an angiographic study (Figure 2a).
Carotid body tumors are composed by two cells types: the type I cells are the chief or paraganglionic cells; the type II cells are the sustentacular cells.
For example, paragangliomas of the adrenal medulla are pheochromocytomas, and paragangliomas of the carotid bifurcation are carotid body tumors.
More carotid body cells survived in the recent experiment on monkeys, Lopez-Barneo says.
Proceeds from the financing will be used to support development of Cibiem's proprietary, minimally invasive, catheter-based approach focused on Carotid Body Modulation[TM] (CBM) for the treatment of sympathetic nervous system-mediated diseases such as hypertension, heart failure, diabetes and renal failure.
Since chronically hypoxic patients often develop paragangliomas arising from the carotid body, a critical site of oxygen sensing, activation of hypoxia-inducible pathways appears to be essential to the pathogenesis of these tumors and may greatly contribute to their hypervascularity.
1) The carotid body is the most common site for these tumours to arise, and these carotid body tumours characteristically splay the internal and external carotid arteries.

2) When they do occur in the head and neck, the most common locations are the carotid body at the bifurcation of the common carotid artery (carotid body tumor), the jugular bulb (glomus jugulare), the tympanic plexus (glomus tympanicum), and the vagus nerve ganglia (glomus vagale).
Magnetic resonance imaging of the head and neck demonstrated multiple skull base lesions consistent with bilateral carotid body tumors, a left glomus jugulare, and a right glomus vagale.
In the poststyloid space, they are associated with the carotid body, the jugular bulb, or the vagus nerve.
The first case involved a poorly differentiated metastatic carcinoma of oropharyngeal origin that mimicked a carotid body tumor.
High on the list of working differential diagnoses were glomus vagale, schwannoma, neurofibroma, squamous cell carcinoma, and carotid body tumor.
