We present another case of delayed intracerebral hemorrhage after a ventriculoperitoneal (VP) shunting procedure. In this case, a right occipital intraparenchymal hematoma and associated intraventricular hemorrhage occurred six days after the operation for hydrocephalus secondary to subarachnoid hemorrhage in a 64 year old woman. It is a rare complication of VP shunting, with few cases reported previously in the literature. The presumed mechanism is the erosion of a cerebral blood vessel secondary to a close contact with the ventricular catheter; bleeding disorder, vascular malformation, head trauma or brain tumor were excluded in this patient.
Presentamos un caso de hemorragia intracerebral tardía tras la colocación de una derivación ventriculoperitoneal. Una paciente de 64 años de edad, con hidrocefalia secundaria a una hemorragia subaracnoidea, sufre una hemorragia intraparenquimatosa occipital derecha con hemorragia intraventricular secundaria seis días después de la intervención quirúrgica. Se trata de una complicación rara de la derivación ventriculoperitoneal, con pocos casos publicados anteriormente. El mecanismo supuesto es la erosión de un vaso sanguíneo secundaria a un íntimo contacto con el catéter proximal de la derivación; trastornos sanguíneos, malformaciones vasculares cerebrales, traumatismo craneal o tumor cerebral fueron excluidos en esta paciente.
