Resumen
Introducción

El tratamiento quirúrgico de los aneurismas intracraneales múltiples sigue siendo un problema complejo.

Objetivos

Analizar las características de los aneurismas múltiples, las posibilidades terapéuticas y los resultados del tratamiento quirúrgico.

Pacientes y Método

De un total de 514 pacientes con aneurismas intracraneales hubo 113 con aneurismas múltiples (21.5 %) y 256 sacos: 244 del sistema carotídeo y 12 del sistema vertebrobasilar. Los pacientes fueron clasificados en tres grupos siguiendo los criterios de Orz. El método de tratamiento fue la intervención quirúrgica en uno o dos tiempos. Los pacientes se encontraban en grado I y II de la Escala de la Federación Mundial. Los resultados se evaluaron con la Escala de Pronósticos de Glasgow.

Resultados

El promedio fue de 2.3 sacos por paciente. Fue elevada la proporción de lesiones en la región de la comunicante posterior y baja en la arteria cerebral media. El 54 % de los pacientes correspondió al grupo 1 de Orz, el 35 % al grupo 2 y el 11% al grupo El 100 % de las lesiones del grupo 1, el 82% de las lesiones del grupo 2 y el 33% de las lesiones del grupo 3 se intervinieron en un solo tiempo quirúrgico. El 79 % de los pacientes obtuvieron una recuperación completa. La mortalidad quirúrgica fue del 4.4 %.

Conclusiones

Las características particulares de las lesiones aneurismáticas encontradas en esta serie, el buen estado clínico preoperatorio y la elevada proporción de pacientes intervenidos en un solo abordaje determinaron estos resultados.

Among 514 patients with intracranial aneurysms, there were 113 with multiple aneurysms (21.5%) and 256 sacs: 244 located at the carotid system and 12 in the vertebrobasilar system. Patients were classified in three groups according to Orz criteria. Surgical treatment was performed in one or two stage operations.

Patients were at I or II Grades of the World Federation Scale. The Glasgow Outcome Scale was used for evaluating surgical results.

Results

Patients sacs rate was 2.3. The location of aneurysms was high in the posterior communicating artery and very low at the middle cerebral artery 100% of the lesions in Orz group 1,82% in group 2 and 33% in group 3 were operated on in one stage operation. Postoperative follow-up showed that 79% of the patients made a completely recovery. Mortality rate was 4.4%.
