The endoscopic trans-fourth ventricle aqueductoplasty and stent placement for the treatment of trapped fourth ventricle; Stent blockage complications under estimated

摘要

I read the article entitled "endoscopic trans fourth ventricle aqueductoplasty and stent placement for the treatment of trapped fourth ventricle" with interest and congratulate the authors for their good results. The trapped fourth ventricle can be treated by two different methods. One way is to put in. ventriculo-peritoneal (VP) shunt and communicate fourth ventricle with cisterna magna if there is long segment aqueductal stenosis. The other way is by communicating fourth ventricle with third ventricle and cisterna magna which do not require VP shunt unless there is a complex hydrocephalus (defect in permeation of cerebrospinal fluid in the basal cisterns or the defect in the absorption).
