The researchers, who conducted the study of rats, said that despite its small size the carotid body
has the highest blood flow of any organ in the body.
The carotid body tumor resection surgery requires adequate monitorization for cerebral ischemia and signs of hemodynamic and respiratory events.
Current concepts for the surgical management of carotid body tumor.
It is demonstrated that chronic exposure to hypoxia is responsible of a compensatory hypertrophy of carotid body
and some studies have shown that long exposure to high altitudes appears to be correlated with a 10-fold higher incidence of carotid body
tumors but no increase in the incidence of paragangliomas located in other sites has been reported.
Cibiem is a medical device company leveraging its 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.
There are two previous reports of vagal paragangliomas mimicking a carotid body
Metastatic disease from cervical paragangliomas is usually confined to the neck, and it is said to be more common in cases of glomus vagale tumors than in cases of carotid body
CT and MRI findings are keys to the diagnosis, and they can be useful in differentiating a carotid body
tumor from meningiomas or other neurogenic tumors.
Differentiation among carotid body
, intravagal, and jugulotympanic paragangliomas depends on proper localization of the mass in relation to the carotid bifurcation, the internal carotid artery, the internal jugular vein, and the skull base.
The carotid body
is located at the carotid bifurcation.
tumors typically present as painless neck masses just lateral to the tip of the hyoid bone.
The carotid body
is a chemoreceptor located in the adventitia posteromedially to the bifurcation of the common carotid artery.
