Resumen
Introducción

La dilatación infundibular (DI) de la arteria comunicante posterior (AComP) se define como la dilatación cónica, triangular o en forma de embudo, menor de 3mm, en el origen de la AComP de la arteria carótida interna. El propósito del presente trabajo es presentar la experiencia propia en el tratamiento microquirúrgico de la DI de la AComP, revisar la bibliografía y proponer algoritmos para optimizar su manejo clínico y microquirúrgico.

Material y métodos

Se han estudiado nueve casos de DI intervenidos a través de un abordaje pterional. En cuatro pacientes con hemorragia subaracnoidea (HSA) la DI se consideró la única causa del sangrado; en otros cuatro pacientes la DI se intervino tras una HSA por ruptura de otra lesión aneurismática; finalmente, en un paciente con pseudoxantoma elástico la DI se intervino de forma preventiva.

Resultados

En ocho casos se procedió al clipaje de la DI y cierre de la AComP y en uno al reforzamiento de la DI al tratarse de una AComP del tipo fetal. No aparecieron complicaciones salvo una paresia transitoria del III par. El Glasgow Outcome Scale al alta y al año fue de 5 en todos los casos.

Conclusiones

La DI de la AComP es una lesión de significado no aclarado, pero que plantea la necesidad de considerar su tratamiento en algunas ocasiones: 1. En pacientes con aneurismas rotos sometidos a cirugía y DI homolateral se recomienda explorar y tratar la lesión; 2. En pacientes con aneurismas rotos tratados con embolización con DI no tratada y en aquellos tratados con microcirugía con una DI contralateral, se considerarán en cada caso los factores de riesgo para indicar un tratamiento microquirúrgico; 3. En los pacientes con DI como única lesión vascular asociada a una HSA debe repetirse la angiografía y, en ausencia de otra explicación del sangrado, considerar el tratamiento microquirúrgico; 4. El hallazgo de una DI en pacientes sin sangrado es una indicación de observación con neuroimagen y control de los factores generales de riesgo vascular, en ausencia de sustanciales factores de riesgo.

Summary
Introduction

The infundibular dilatation (ID) of the posterior communicating (PCom) artery is defined as the conic, triangular or infundibular shaped, less than 3mm wide, origin of the PCom artery from the internal carotid artery. The purpose of this paper is to present the personal experience in the microsurgical management of the ID, to review the literature and to propose some algorithms to improve its clinical and microsurgical management.

Material and methods

Nine cases of ID have been operated on through a pterional approach. In four patients with subarachnoid hemorrhage (SAH) the ID was considered as the potential source of the bleeding; in four cases the ID was treated after a SAH due to the rupture of an aneurysm; finally, an ID was treated in patient with diagnosis of pseudoxantoma elasticum.

Results

In eight cases the ID was clipped and the Pcom artery subsequently occluded and in the remaining case the ID was associated with a fetal PComA and the ID was reinforced. There were no complications excepting a transitory third cranial nerve paresis. The Glasgow Outcome Scale was 5 in all cases at discharge and one year later.

Conclusions

The true significance of the ID remains unknown, but in some instances it is necessary to consider its management: 1. In patients with ruptured aneurysms submited to microsurgical clipping and with an ipsilateral ID, the lesion must be explored and treated; 2. In patients with ruptured aneurysms treated with endovascular procedures or harbouring an ID contralateral to a microsurgically treated aneurysm, the microsurgical indication will be done after considering all risk factors; 3. In patients with SAH and an ID as the only potential source of the bleeding there would be an indication for microsurgical exploration; 4. The incidental finding of an ID should be indication for observation in absence of major risk factors.
