Ventriculosubgaleal shunt: an institutional experience.

BACKGROUND AND OBJECTIVE

Ventriculosubgaleal shunt (VSGS) was first described in 1896 by Von Mickulicz. It allows CSF to flow from the dilated ventricle to the subgaleal pouch developed in the scalp through a small silicon tube. The possibility that the hydrocephalic state in infants caused by hemorrhage/ + infection will only last a short while prompts the search for temporary management options, which must be a closed system in order to be more physiological given that these infants are frequently preterm (LBW) and immunologically immature. VSGS is one such option. To the best of our knowledge, most of the studies done on VSGS are retrospective, and there are very few prospective studies (none on Indian subjects till now). We aim to study the efficacy of VSGS in preventing the placement of VP Shunt in infants with post-hemorrhagic/post-infectious hydrocephalus.

METHOD

Our study (prospective observational) comprises 30 infants in whom VSGS was inserted at Sir Gangaram Hospital between August 2017 and October 2020 and who were followed up for 6 months after VSGS insertion.

RESULT

Most of the infants had a birth weight between 1501 and 2000 g with a mean gestational age of 31.2 weeks. Thirteen out of 30 patients did not require the placement of VP shunt. The rates were higher in the post-infectious group (50%) in contrary to the post hemorrhagic group where it was 38.8%. Complications encountered with VSGS include CSF leak (13.3%) and wound dehiscence (6.6%). None had VSGS blockage, migration, and infection.

CONCLUSION

We conclude that VSGS is a reliable, safe, easy to perform, and temporary treatment option in infants with post-hemorrhagic and post-infectious hydrocephalus and helps in avoiding VP shunt dependency in nearly half of them.
