A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control.
Traumatic injuries to the VAGUS NERVE. Because the vagus nerve innervates multiple organs, injuries in the nerve fibers may result in any gastrointestinal organ dysfunction downstream of the injury site.
Traumatic injuries to the HYPOGLOSSAL NERVE.
A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition.

Familial carotid body tumors: a closer look. (1/77)

PURPOSE: A family spanning three generations with a history of familial carotid body tumors (CBTs) was studied, and previously proposed hypotheses of tumor characteristics and genetic mode of transmission were addressed. METHODS: Clinically occult lesions in adult subjects were detected by means of high-resolution computed tomography. RESULTS: A 60% incidence of bilaterality of CBTs associated with multiple paragangliomas was noted in the family studied. The genetic mode for CBTs in this family was not simple autosomal dominant transmission and appeared to be paternally directed with complete penetrance. CONCLUSION: In patients with familial CBTs, high-resolution computed tomography is recommended for early screening as a means of prompting diagnosis and definitive treatment, an approach that minimizes morbidity and facilitates surgical excision.  (+info)

Mutations in SDHD, a mitochondrial complex II gene, in hereditary paraganglioma. (2/77)

Hereditary paraganglioma (PGL) is characterized by the development of benign, vascularized tumors in the head and neck. The most common tumor site is the carotid body (CB), a chemoreceptive organ that senses oxygen levels in the blood. Analysis of families carrying the PGL1 gene, described here, revealed germ line mutations in the SDHD gene on chromosome 11q23. SDHD encodes a mitochondrial respiratory chain protein-the small subunit of cytochrome b in succinate-ubiquinone oxidoreductase (cybS). In contrast to expectations based on the inheritance pattern of PGL, the SDHD gene showed no evidence of imprinting. These findings indicate that mitochondria play an important role in the pathogenesis of certain tumors and that cybS plays a role in normal CB physiology.  (+info)

Bilateral carotid body paraganglioma: case report. (3/77)

CONTEXT: Surgical treatment of carotid body paragangliomas is a challenge to the surgeon because of the large vascularization of the tumor, involvement of the carotid vessels and the close anatomical relationship with the cranial nerves. CASE REPORT: A 63-year-old patient was submitted to resection of two carotid body paraganglioma tumors found in the right-side and left-side carotid bodies at the bifurcation of the common carotid arteries. Two surgeries were performed at different times and neither of them presented any morbidity. Arteriography was fundamental for diagnosis of the small, asymptomatic tumor on the right side. DESIGN: Case Report  (+info)

Baroreflex failure syndrome after bilateral excision of carotid body tumors: an underestimated problem. (4/77)

Carotid body tumors (CBTs) are relatively rare paragangliomas that develop from neural crest cells at the bifurcation of the common carotid artery. They are generally slow growing and benign. Excision is currently considered the treatment of choice, although vascular and especially neural injuries are still relatively frequent in patients with large or bilaterally resected tumors. The baroreflex failure syndrome (BFS) has recently been identified as a severe, rarely recognized, and certainly underestimated complication after the bilateral excision of CBTs. The present report describes a case of a bilateral CBT followed by BFS and reviews the experiences reported in the literature. In light of the low incidence of malignancy of these tumors, their biologic behavior, their very high rate of cranial nerve palsy, and the occurrence of BFS in bilaterally resected paragangliomas, the current practice of bilaterally removing these tumors is questioned.  (+info)

Power Doppler scanning in the diagnosis of carotid body tumors. (5/77)

The aim of this work was to show contribution of power Doppler imaging in the diagnosis of the carotid body tumors. Six patients with a nontender mass beneath the mandibular angle were evaluated with gray scale and power Doppler sonography. Well-defined, solid, weakly hyperechoic masses were noted on gray scale sonography in the carotid bifurcation. Power Doppler sonography showed abundant flow, characterized as an intense blush, throughout the entire tumor in all patients. We believe that invasive and expensive diagnostic modalities are not necessary to evaluate carotid body tumors. Gray scale sonography and power Doppler imaging are sufficient for primary diagnosis of carotid body tumors.  (+info)

Malignant carotid body tumor: a case report. (6/77)

Carotid body tumors (CBTs) have an unpredictable history with no correlation between histology and clinical behavior. Of reported cases since 1891, local and distant metastases appear in approximately 10% of cases and remain the hallmark of malignancy. Currently, there are not enough data to support a single treatment regimen for malignant CBTs. The reported case demonstrates some unanswered issues with regard to malignant CBTs to include lymph node dissection, the need for carotid resection, and the role of radiation therapy. A 46-year-old pathologist underwent a resection of a Shamblin I CBT, to include jugular lymph node sampling, without complication. There was lymph node involvement, and tumor cells were found on the margins of the pathologic specimen. Subsequent carotid resection with reversed interposition saphenous vein graft and modified neck dissection were performed again without complication. Follow-up at 4 years has been uneventful. Diagnosis of CBTs with the use of magnetic resonance angiography, magnetic resonance imaging, color flow duplex scanning, and the role of arteriography are reviewed. The current treatment options are discussed with reference to primary lymph node sampling, carotid resection, and neck dissection in malignant cases. This case demonstrates that the unpredictable nature of CBTs and their malignant potential warrant aggressive initial local treatment to include jugular lymph node sampling and complete tumor resection.  (+info)

Long-term effects of carotid sinus denervation on arterial blood pressure in humans. (7/77)

BACKGROUND: After experimental carotid sinus denervation in animals, blood pressure (BP) level and variability increase markedly but normalize to preoperative levels within 10 to 14 days. We investigated the course of arterial BP level and variability after bilateral denervation of the carotid sinus baroreceptors in humans. METHODS AND RESULTS: We studied 4 women (age 41 to 63 years) who were referred for evaluation of arterial baroreflex function because of clinical suspicion of carotid sinus denervation attributable to bilateral carotid body tumor resection. The course of BP level and variability was assessed from repeated office and 24-hour ambulatory measurements (Spacelabs/Portapres) during 1 to 10 years of (retrospective) follow-up. Rapid cardiovascular reflex adjustments to active standing and Valsalva's maneuver were assessed. Office BP level increased from 132/86 mm Hg (range, 118 to 148/80 to 92 mm Hg) before bilateral surgery to 160/105 mm Hg (range, 143 to 194/90 to 116 mm Hg) 1 to 10 years after surgery. During continuous 24-hour noninvasive BP recording (Portapres), a marked BP variability was apparent in all 4 patients. Initial symptomatic hypotension on change to the upright posture and abnormal responses to Valsalva's maneuver were observed. CONCLUSIONS: Acute carotid sinus denervation, as a result of bilateral carotid body tumor resection, has a long-term effect on the level, variability, and rapid reflex control of arterial BP. Therefore, in contrast to earlier experimental observations, the compensatory ability of the baroreceptor areas outside the carotid sinus seems to be of limited importance in the regulation of BP in humans.  (+info)

Baroreflex control of muscle sympathetic nerve activity after carotid body tumor resection. (8/77)

Bilateral carotid body tumor resection causes a permanent attenuation of vagal baroreflex sensitivity. We retrospectively examined the effects of bilateral carotid body tumor resection on the baroreflex control of sympathetic nerve traffic. Muscle sympathetic nerve activity was recorded in 5 patients after bilateral carotid body tumor resection (1 man and 4 women, 51+/-11 years) and 6 healthy control subjects (2 men and 4 women, 50+/-7 years). Baroreflex sensitivity was calculated from changes in R-R interval and muscle sympathetic nerve activity in response to bolus injections of phenylephrine and nitroprusside. In addition, sympathetic responses to the Valsalva maneuver and cold pressor test were measured. The integrated neurogram of patients and control subjects contained a similar pattern of pulse synchronous burst of nerve activity. Baroreflex control of both heart rate and sympathetic nerve activity were attenuated in patients as compared with control subjects [heart rate baroreflex sensitivity: 3.68+/-0.93 versus 11.61+/-4.72 ms/mm Hg (phenylephrine, P=0.011) and 2.53+/-1.36 versus 5.82+/-1.94 ms/mm Hg (nitroprusside, P=0.05); sympathetic baroreflex sensitivity: 3.70+/-2.90 versus 7.53+/-4.12 activity/100 beats/mm Hg (phenylephrine, P=0.10) and 3.93+/-4.43 versus 15.27+/-10.03 activity/100 beats/mm Hg (nitroprusside, P=0.028)]. The Valsalva maneuver elicited normal reflex changes in muscle sympathetic nerve activity, whereas heart rate responses were blunted in the patients with bilateral carotid body tumor resection. Maximal sympathetic responses to the cold pressor test did not differ between the two groups. Denervation of carotid sinus baroreceptors as the result of bilateral carotid body tumor resection produces chronic impairment of baroreflex control of both heart rate and sympathetic nerve activity. During the Valsalva maneuver, loss of carotid baroreflex control of heart rate is less well compensated for by the extra carotid baroreceptors than the control of muscle sympathetic nerve activity.  (+info)

The carotid body is a small structure weighing 12 mg located in the adventitia of carotid artery bifurcation acting as a chemoreceptor. Carotid body tumour (CBT); formerly known as chemodectoma is a rare, highly vascular, mostly benign tumour arising from the paraganglia of carotid body; hence, the name (carotid paraganglioma). The high vascularity and proximity to cranial nerves and major vessels make this tumour a surgical challenge. Abundant literature has been written about CBT in the last century with a continuous debate regarding its etiology, natural history, biological behavior, proper technique of excision, and the morbidity and mortality associated with its resection. The purpose of this review article is to simplify understanding the basic and clinical aspects of this challenging neoplasm.
From these findings, several perioperative anesthetic implications2 can be anticipated during resection. First, because a carotid body paraganglioma is a neuroendocrine tumor, release of catecholamines or association with a pheochromocytoma should be suspected. Endocrine evaluation will determine if preoperative α-blockade is needed to prevent intraoperative hypertensive crises. The tumor blush from the neoplastic vascular proliferation is indicative of an increased risk of profuse hemorrhage. Consequently, tumor biopsy is contraindicated. Preoperative tumor embolization should be considered3 and the need for rapid blood transfusion anticipated. The ICA plaque may lead to cerebrovascular accidents by obstruction of cerebral blood flow and by embolic stroke from plaque dislodgement during ICA dissection. Finally, tumor invasion may lead to carotid sinus hypersensitivity, and carotid sinus manipulation may precipitate severe bradycardia ...
Results: Among the 27 patients 63% were women, 83% were asymptomatic, and the mean age was 50 years (range 21-79). None of the tumors were hormonally active, mean size was 3.2 centimeters (range 1.6 - 5.0 cm), and the Shamblin class distribution was: 9% type I, 48% type II, and 43% type III. Men were found to have significantly larger tumors on presentation (4.1 cm vs 2.8 cm, p=0.001), though this did not correlate to an increased complication rate. Preoperative embolization was performed in 8 patients, which did not correlate with tumor size. All tumors were completely resected with a mean estimated blood loss of 217 mL (range 5 1000 mL) and no evidence of metastatic disease. The 30-day death, stroke, and cranial nerve injury rates were 0%, 9%, and 27%, respectively. Cranial nerve injuries included 18% vagus, 4.5% hypoglossal, 4.5% facial, and 4.5% glossopharyngeal, but no permanent injuries. Mean length of stay was 2.7 days (range 1-7 days). At a mean follow-up of 12 months (range 1-63 ...
CT of the neck is helpful for diagnosis and can identify any local lymph node enlargement or bony erosions. Additionally, MR can help determine the relationship of the tumor with respect to the carotid vessels and other neck structures and if there are multiple paragangliomas present. A classic finding of the carotid body tumor is splaying of the internal and external carotid arteries. On both enhanced CT and MR, the carotid body tumors and other paragangliomas are intensely enhancing due to their extensive vascularity. Sometimes small flow voids can be seen on nonenhanced MR, causing a speckled or salt and pepper appearance of the tumor. On dynamic enhanced CT or MR, there will be a rapid enhancement, a high peak, and rapid washout due to early arteriovenous shunting of the tumor. Conventional catheter angiography reveals similar findings. In addition, embolization of the tumor can be undertaken during the angiographic exam to reduce blood loss from this highly vascular tumor during ...

jdempsey{at}wisc.edu. Question: Does the carotid body response to chronic intermittent hypoxia (CIH) differ between neonates and adults?. Background: The carotid body is a sensory organ located near the bifurcation of the carotid artery and is responsible for detecting changes in the partial pressure of oxygen in arterial blood. In adult rodents, during CIH, the carotid body is theorized to evoke the reflexes that mediate cardiorespiratory changes and results in a long-lasting increase in baseline sensory activity known as sensory long-term facilitation (LTF). In contrast to adults, the carotid bodies of neonatal rodents are immature and respond poorly to hypoxia. To better understand the physiology of neonatal carotid bodies, Pawar et al. explored whether CIH evokes sensory LTF and whether the effects of CIH are reversible in neonatal carotid bodies.. Observations: CIH augmented the hypoxic sensory response in both adults and neonates; however, the neonates displayed more susceptibility to the ...

The carotid body (CB) is the main arterial chemoreceptor in charge of adjusting ventilatory and cardiovascular function during changes in arterial blood gases. Regardless this essential function, the CB has been implicated in the sensing of other physiological signals such as changes in blood flow and glucose levels. More important, malfunction of the CB chemoreceptors has been associated with the progression and deterioration of several disease states such as hypertension, heart failure, renal failure, insulin resistance, diabetes and sleep apnea. Although the mechanisms involved in the alterations of the CB function in pathophysiology are currently under intense research, the development of therapeutic approaches to restore normal CB chemoreflex function remains unsolved. Recently, elegant studies showing the effect of CB neurotomy in pathophysiology have unveiled a key role of these arterial chemoreceptors in the development of autonomic imbalance and respiratory disturbances, and suggest that
Paragangliomas are rare tumors that grow in cells of the peripheral nervous system (i.e. the nerves outside the brain and spinal cord).
Many of these syndromes involving paragangliomas are autosomal dominant, which means that offspring (i.e. children) have a 50% chance of developing the disease.
The major new finding obtained from conscious rats was the clear-cut demonstration that chemoreceptors, as well as baroreceptors, were transiently activated during combined electric stimulation of the carotid sinus and the carotid sinus nerve in conscious rats. The results have shown that when the carotid bifurcation was intact (ie, in the CONT group), combined electric stimulation of the carotid sinus and the carotid sinus nerve elicited a significant hypotensive response. This finding is in line with results obtained in dogs21,22 and drug-resistant hypertensive patients.1,2 Nevertheless, unlike the results seen in dogs23 and drug-resistant hypertensive patients,4 HR did not significantly decrease in intact conscious rats (the CONT group).. It is of interest to note that bilateral carotid body denervation (as in the CHEMO-X group) hampered the hemodynamic influences of the carotid chemoreceptors during combined electric stimulation of the carotid sinus and the carotid sinus nerve in conscious ...

Background: Cardiac paraganglioma is a rare entity of an uncommon neuroendocrine tumor. Clinically, non-secreting tumors are often diagnosed because of their growth effects, secreting tumors present symptoms related to catecholamine. Correct diagnosis of a paraganglioma can be reached by biochemical investigations and imaging. Surgical resection is the treatment of choice and has to be planned carefully and interdisciplinarily. Aim: On the basis of a patient with a vague clinical presentation and an unclear situation after primary investigations, we highlight the diagnostic challenge of this rare subset of paragangliomas. Case presentation: We present the case of a 42-year-old woman whose unspecific symptoms and further investigations revealed a paracardiac mass with unknown local behavior and dignity. Surgical resection and histopathological examination led to the diagnosis of a cardiac paraganglioma. Conclusion: Cardiac paragangliomas are extremely rare, but may be treated curatively by resection

The root cause of FAP is understood to be a genetic mutation-a flaw in the bodys tumour suppressor genes that prevent development of tumours. The flaw allows numerous cells of the intestinal wall to develop into potentially cancerous polyps when they would usually reach the end of their life; inevitably one or more will eventually progress and give rise to cancer (7% risk by age 21, rising to 87% by age 45 and 93% by age 50). The flawed genes do not trigger cancer, but rather, they reduce the bodys ability to protect against the risk of aged cells becoming cancerous. Even with the flawed gene, it may still take time before a cell actually does develop that is cancerous as a result, and the gene may in some cases still partially operate to control tumours, therefore cancer from FAP takes many years to develop and is almost always an adult-onset disease. The second form of FAP, known as attenuated familial adenomatous polyposis has the APC gene functional but slightly impaired. It is therefore ...

In this study we used five surgically removed human CBs to characterize the CB transcriptome with microarray and PCR analyses, and compared the results with mice data. In silico approaches demonstrated a unique gene expression profile of the human and mouse CB transcriptomes and an unexpected upregulation of both human and mouse CB genes involved in the inflammatory response compared to brain and adrenal gland data.

Paragangliomas of the head and neck are highly vascular and usually clinically benign tumors arising in the paraganglia of the autonomic nervous system. A significant number of cases (10-50%) are proven to be familial. Multiple genes encoding subunits of the mitochondrial succinate-dehydrogenase (SDH) complex are associated with hereditary paraganglioma: SDHB, SDHC and SDHD. Furthermore, a hereditary paraganglioma family has been identified with linkage to the PGL2 locus on 11q13. No SDH genes are known to be located in the 11q13 region, and the exact gene defect has not yet been identified in this family. We have performed a RNA expression microarray study in sporadic, SDHD- and PGL2-linked head and neck paragangliomas in order to identify potential differences in gene expression leading to tumorigenesis in these genetically defined paraganglioma subgroups. We have focused our analysis on pathways and functional gene-groups that are known to be associated with SDH function and paraganglioma

nonfunctional, extra-adrenal, retroperitoneal paraganglioma is a rare, neuroendocrine, and potentially malignant tumor. from chromaffin cells along the sympathetic and parasympathetic chains [1]. Parasympathetic paragangliomas are usually inactive and located mostly in the neck and skull base, while sympathetic paragangliomas are primarily situated in the retroperitoneum and create and secrete norepinephrine [2 generally,3]. Up to 15% of retroperitoneal paragangliomas are nonfunctional, or more to 10% are practical without medical manifestation, although they resemble functional ones and immunologically [4-6] histologically. Their clinical demonstration varies based on their area, size, and secretion status, while their diagnosis and treatment may be challenging due to their close proximity to major vessels and surrounding organs, demanding multidisciplinary medical approach and cooperation [2,7,8]. Our study aims to underline the importance of a multidisciplinary medical approach and the ...
Paraganglioma is a rare cancer that originates in the nerve cells of the adrenal glands, organs on top of each kidney that produce important hormones. Paraganglioma that develops in the center of the adrenal gland is called pheochromocytoma. Paraganglioma that forms outside of the adrenal gland, often along blood vessels and nerves in the head and neck, is called extra-adrenal paraganglioma, or simply paraganglioma.. Each year, between 2 and 8 people per million worldwide are diagnosed with paraganglioma and pheochromocytoma.1 Ten percent of all cases occur in children.2 In both adults and children, pheochromocytoma is more common than paraganglioma.2 No known environmental, dietary, or lifestyle risk factors have been associated with these cancers. However, paraganglioma and pheochromocytoma can be hereditary diseases:3 one study reported that about 41 percent of patients diagnosed with one of these diseases in the U.S. carry inherited genetic mutations that increase the risk of malignancy.1 ...
Ivanhoe Newswire) Variations of a gene are associated with a type of tumor that forms within the adrenal gland, and were found in an age group uncommon for these types of tumors.. Pheochromocytomas and paragangliomas are types of tumors. Pheochromocytomas form in the adrenal gland causing it to make too much adrenaline.. Pheochromocytomas can cause high blood pressure, pounding headaches, heart palpitations, flushing of the face, nausea, and vomiting. Paragangliomas are rare, usually benign tumors that may develop at various body sites. Despite a broad spectrum of susceptibility genes for these tumors, the molecular basis for the majority of pheochromocytomas and paragangliomas, including most of the sporadic and rare familial cases, remains unknown, according to background information in the article. These observations support the existence of additional pheochromocytoma susceptibility genes, which may account for some of the genetically undefined cases, the authors were quoted as ...
