Ventriculosubgaleal shunt as a proposed technique for post-infectious hydrocephalus.

BACKGROUND: The management of post-infectious hydrocephalus (PIH) remains challenging for neurosurgeons. It requires a temporary diversion procedure till the normalization of CSF parameters prior to the permanent one. Ventriculosubgaleal shunt (VSGS) was widely used in pediatric cases with post-hemorrhagic hydrocephalus (PHH). However, its role in PIH is still lacking. This study was done to elucidate the safety and efficacy of VSGS as a temporary CSF diversion procedure before the permanent one in patients with PIH. PATIENTS AND METHODS: This retrospective investigation analyzed the data of 50 consecutive cases who underwent VSGS for PIH. RESULTS: The age of the included patients ranged between 1 and 10 months. Twenty-six cases had meningitis and or ventriculitis (52%), while the remaining had shunt infection. At follow-up, arresting of hydrocephalus was noted in ten patients (20%), while another 36 cases required the permanent diversion procedure within 35 days. Regarding the shunt complications, scalp infection, tissue breakdown, and shunt exposure were encountered in ten cases (20%), while CSF leakage was noted in 12 cases (24%). Shunt migration was noted in only two patients (4%). Shunt revision was needed in 16 cases (32%). Mortality was encountered in four cases (8%) because of sepsis. Risk factors for morbimortality included younger age, lower weight, male gender, and meningitis and or ventriculitis. CONCLUSION: VSGS is a safe and effective procedure in infants awaiting definitive VPS for postinfectious hydrocephalus. It was proven that VSGS has shortened the hospital stay and the economic burden on the country.

Endoscopic Management of Pediatric Complex Hydrocephalus.

OBJECTIVE: To define the role of neuroendoscopy as an adjuvant technique for the management of pediatric complex hydrocephalus. METHODS: We performed a retrospective analysis of a series of pediatric patients who had undergone surgery for complex hydrocephalus from January 2002 to March 2017 at 2 pediatric neurosurgery units in Rome, Italy and Mansoura, Egypt. The endoscopic procedures performed included cyst or membrane fenestration, septum pellucidotomy, foraminoplasty, and aqueductoplasty with or without a stent. In selected cases, endoscopic third ventriculostomy was performed as a combined procedure. The mean follow-up period was 5 years. RESULTS: A total of 68 patients (26 females, 42 males), with a mean age of 2 years (range, 0-18), underwent 109 endoscopic procedures. Of the 68 patients, 39 (57%) were affected by multiloculated hydrocephalus, 17 by isolated lateral ventricle (24.6%), 3 by an excluded lateral ventricle horn (4.3%), 7 by an isolated fourth ventricle (10.1%), and 1 each by an isolated third ventricle and a cavum septi pellucidi cyst. The overall postoperative complications rate was 28% (shunt infection, 16.1%; shunt malfunction, 8.8%; subdural collection, 2.9%). At the latest clinical follow-up visit, 65% of the children had only 1 shunt, 25% (n = 17) had a double ventricular catheter, and 10% (n = 7) were shunt free. CONCLUSIONS: We have confirmed that neuroendoscopy has a main role in the long-term management of complex hydrocephalus, significantly contributing to the reduction of the number of shunts and the shunt revision rate. Neuronavigation should be performed in all cases in which the ideal trajectory should be established.
