Objective: Endoscopic third ventriculostomy (ETV) is the therapy of choice in obstructive hydrocephalus. in general the success rate scores between 60–85%. However, only a short follow-up period was evaluated in most studies since most surgical failures become evident within the first 8 weeks after surgery.
Methods: Data of all ETVs performed between 1993 and 1999 at the Neurochirurgische Universitätsklinik Mainz were retrospectively evaluated.
Results: Of 113 patients and 126 procedures, a complete data set was available for analysis. The mean follow-up time was 7 years with a maximum of 16 years. The perioperative complication rate was 9%. The clinical success rate at three months after surgery was 82%. This success rate remained almost unchanged over the years with a success rate of 78% after 16 years follow-up. The patient's age and general condition as well as hydrocephalus etiology at the time of surgery had a significant impact on the success rate while prior shunt dependence did not influence the ETV success.
Conclusions: All in all, this study shows that the early success rate of ETV remains almost unchanged up to 16 years after surgery. Major influencing factors for ETV success are: age, patients' preoperative health status and hydrocephalus etiology. A prior shunting procedure has no influence.
