Brain ventricle index evaluation after Ina-Shunt implantation in congenital hydrocephalus patients

Abstract

Background: One of the management of hydrocephalus is using a shunt system. At the end of 1980, a self-made pumping system with two semilunar valves was built to ensure the cerebrospinal fluid flows in one direction. In November 2016, the production of the shunt system with a semilunar valve was made by a different manufacturer by the name of Ina-Shunt. The product has the same working system as before, and the production mode is similar. Further assessment of this new product needs to be done. Calculating the Evans ratio in the radiological examination can be used to assess its effectiveness in the treatment of hydrocephalus. This study examines the Evans ratio changes in patients who underwent ventriculoperitoneal (VP) shunt using Ina-Shunt.

Methods: This study was a prospective experimental study conducted on patients diagnosed with congenital communicating hydrocephalus who underwent VP shunt surgery using an Ina-Shunt device in Yogyakarta, Surabaya, and Jakarta. The ventricular index (Evans ratio) of pre- and two-week postoperative patients was calculated using head computed tomography scan software. The data was then statistically analyzed using paired t-test.

Results: Thirty-one subjects with congenital communicating hydrocephalus underwent VP shunt using Ina-Shunt in Yogyakarta, Jakarta, and Surabaya. There was a significant difference between the preoperative Evans ratio value of 0.62 + 0.016 and the post-operative Evans ratio of 0.59 + 0.015 (p < 0.05).

Conclusion: There was a change in brain ventricle index that showed in decreasing Evans ratio after VP shunt surgery using Ina-Shunt in pediatrics diagnosed with congenital communicating hydrocephalus. A larger sample and longer follow-up were needed for serial Evans ratio changes.
