Fallo baroreflejo tras intervención de un quemodectoma
2004
We present a case of baroreflex failure secondary to a unilateral injury of the glossopharyngeal nerve. The patient was operated for a left-sided chemodectoma in the carotid body. Some months after surgery she started to report presyncopal episodes exacerbated by mental stress and when standing up. During these episodes, the patient presented hypertensive crises and tachycardia. However, blood pressure was below normal ranges at rest. The diagnosis was baroreflex failure secondary to unilateral injury of the glossopharyngeal nerve. The case reported herein illustrates the fact that the presence of a bilateral injury is not essentialfor the occurrence of this disorder.
