The overall complications related to ETV as shown in our study were 7.8% with no deleterious sequela like upward herniation. CSF leak was noted in 3 patients while pneumocephlus, meningitis, seizures were observed in 2 patients each, mild hemiparesis was observed in one patient and one patient died due to CSF leak and meningitis.
Our study shows no post-op infection and upward herniation except hemorrhage in 2 (1.3%) patients in which EVD was performed.
In comparison with the study conducted by Rappaport, Schmid and Seiler on External ventricular drainage used in these situations reported 10% and 4.9% infection rate respectively and upward herniation or haemorrhage24.
