Los aneurismas verdaderos de la arteria comunicante posterior se originan de la pared de esta arteria sin comprometer la carótida interna, lo que permite diferenciarlos de los aneurismas del segmento comunicante posterior. Estas lesiones son infrecuentes, por lo que sus relaciones anatómicas no han sido descritas en detalle y los reportes referentes a su tratamiento endovascular son escasos.
En el presente manuscrito se expone el caso de un paciente portador de un aneurisma verdadero de la arteria comunicante posterior izquierda que fue tratado por vía endovascular. Además se presenta una revisión de la literatura para ilustrar los detalles anatómicos y técnicos más relevantes para lograr su tratamiento exitoso.
True posterior communicating artery aneurysms originate exclusively from the wall of this artery and should be differentiated from aneurysms of the posterior communicating segment of the distal carotid artery. As these lesions are rare, their anatomical relationships have been poorly described; likewise, reports concerning their endovascular treatment are extremely rare and the technical aspects poorly detailed.
A case of a patient with a true aneurysm of the left posterior communicating artery treated by endovascular coiling is presented. A literature review was also conducted to illustrate the anatomical and technical details relevant to achieving its successful treatment.
