Endoscopic treatment of ventriculomegaly hydrocephalus caused by primary or secondary aqueduct obstruction

Objective To explore the indications of surgical treatment of ventriculomegaly hydrocephalus caused by primary or secondary aqueduct obstruction and the prevention of complications. Method Endoscopic treatment of 32 cases of overt ventriculomegaly patients in total, 25 cases were subject to transfrontal -approach endoscopic third ventriculostomy, 1 case was subject to SCC cyst fistulation, 5 cases was subject to suboccipital - approach endoscopic skull cranial fossa cyst resection and cyst - cistema magnafistulation and 1 case was subject to suboccipital approach hydrocephalus plasty. Results After 1-4 years of follow - up, among 32 cases of patients of unstable walking, urinary incontinence, decreased intelligence quotient, psychomotor retardation, the symptoms of 26 cases were significantly improved and the symptoms of 6 cases of patients showed no continuous progression. The post - surgical symptoms of the six cases of patients with preoperative high intracranial pressure symptoms were improved. Conclusions The magnetic resonance imaging test shows the aqueduct stenosis or obstruction is a clear indication of patients of overt ventriculomegaly no matter whether there is clinical symptom of intracranial hypertension or not after surgical treatment As long as attentions are paid to the details during the operation process, the improvement of surgical techniques can avoid the occurrence of complications.
