[Etiopathogenetic differences and therapeutic possibillities of the carotid sinus syndrome. Report of two rare cases (author's transl)].
Two cases of carotid sinus syndrome with peculiar clinical and nosological characteristics are presented. The clinical symptoms were characterized by syncope with bradicardia and hypotension, which occurred contemporarily or independently of each other. The most valuable medical therapy to prevent or got over the syncopal attacks has proved to be one associating  the sympathicomimetic drugs (high dosage dopamine, particularly on demande pacemaker. Complete decrease of symptoms following was obtained only after surgical treatment: denervation of carotid sinus in one case, intracranical section of the glosspharyngeal nerve and of the two vagal termination nearer to IX in the other case. This last result makes it possible to consider the case in question from an original nosological point of view exploiting the pathogenetic importance of stimulating the afferent nerve-fibres of the glossofaryngeal-nerve.
