Endoscopic neurosurgery for the treatment of septum pellucidum cysts / 中国微创外科杂志

ABSTRACT

Objective To discuss the techniques and significance of neuroendoscopic treatment for symptomatic septum pellucidum cysts. Methods A total of 12 patients with symptomatic septum pellucidum cysts were given a cyst-lateral ventricle ventriculostomy via a transcallosal and transventricular approach by using a neuroendoscope 4.0 mm in external diameter(Storz,Germany).Headache,epilepsy,and mental symptoms were prominent clinical manifestations.Two patients were complicated with hydrocephalus. Results Improvement of symptoms was achieved postoperatively in all the 12 patients.Out of 6 patients with a major sign of intracranial hypertension,symptoms completely disappeared in 4 patients and improved in 2 patients.Four patients with epilepsy attacks had no recurrence.A follow-up was made in 12 patients for 6~24 months(mean,18 months).Re-examinations of CT or MRI showed the cysts had decreased in size by 90% in 2 patients.The lesions completely disappeared in 2 patients with hydrocephalus. Conclusions Neuroendoscopic cyst-lateral ventricle ventriculostomy for septum pellucidum cysts is a safe,effective,and minimally invasive operation.
