Resumen
Se hace una breve reseña embriológica de la persistencia de esta comunicación anómala entre los sistemas arteriales carotídeo y basilar. Se muestran los cuadros patológicos asociados a esta malformación (aneurismas). Se aportan 7 casos, sobre 2000 estudios arteriográficos efectuados en el Instituto de Neurocirugía. Constituye, por tanto, una frecuencia del 0,35% coincidiendo con otras estadísticas consultadas que dan cifras que oscilan del 0,2% al 0,4%.
Zusammenfassung
Nach einem kurzen embryologischen Überblick über die Persistenz solcher anormalen Verbindungen zwischen dem arteriellen System der Karotis und der Basilaris werden einige pathologische Fälle (Aneurysmen) dargestellt, die im Zusammenhang mit dieser Mißbildung einer persistierenden A. Trigemini primitiva gefunden wurden. Es handelt sich um 7 Fälle, die unter 2000 arteriographischen Untersuchungen am Institut für Neurochirurgie beobachtet wurden.
Die Frequenz entspricht mit 0,35% den Ergebnissen anderer Statistiken (0,2–0,4%).
Summary
After a brief embryological review concerning persistent anomalous connections between the carotid and basilar systems, some pathological cases are described which occurred in association with this malformation.This report is concerned with 7 cases, which were detected among 2,000 arteriograms performed at the Institute of Neurosurgery.
The incidence of these aneurysms (0.35%) corresponds with the frequency noted in other statistics (0.2–0.4%).
Résumé
Presentation de sept cas d'artère trigéminale. Rappel embryologique de cette anomalie qui correspond à la persistance de communication arteriel carotido-basilaire. Parmi 2000 études, correspondant au materiel de l'Institut de Neurochirurgie, nous avons trouvé sept cas, ce qui fait un pourcentage de 0,35% semblable aux résultats trouvés dans la bibliographie.
Riassunto
Gli AA., dopo un breve accenno embiologico sulla persistenza di anormali collegamenti tra il sistema carotideo e quello basilare, presentano alcuni casi patologici in connessione con detta malformazione.
Si tratta di 7 casi osservati tra 2.000 esami arteriografici effettuati nell'Istituto di Neurochirurgia.
La frequenza corrisponde a quella di altre statistiche (0,2–0,4%).
