Insights
Non-watertight dural closure (non-WTDC) in pediatric cranial surgery is safe and effective. This approach resulted in low rates of clinically significant complications like pseudomeningocele (PM) and cerebrospinal fluid (CSF) leaks.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Surgical Complications
Background:
- Dural closure is critical after intracranial procedures to prevent complications such as pseudomeningocele (PM), cerebrospinal fluid (CSF) leaks, hydrocephalus, and infections.
- Achieving watertight dural closure (WTDC) can be challenging, often necessitating the use of dural substitutes.
- This study evaluates the outcomes of non-WTDC in pediatric patients.
Purpose of the Study:
- To assess the safety and efficacy of non-watertight dural closure (non-WTDC) in pediatric cranial surgery.
- To determine the incidence of postoperative complications associated with non-WTDC.
- To identify factors influencing outcomes in pediatric patients undergoing non-WTDC.
Main Methods:
- Retrospective data collection from 163 pediatric patients (3 months to 18.5 years).
- Exclusion of redo and craniectomy cases.
- Analysis of demographics, surgical indications, dural closure techniques, and postoperative complications.
Main Results:
- Non-WTDC was performed in 89% of cases, with dural substitutes used in 96%.
- A low rate of CSF leak (0.6%) and clinically significant PM (3% at 1 year) was observed.
- No infections occurred; infratentorial location was the only factor associated with PM or need for CSF surgery.
Conclusions:
- Non-WTDC in pediatric cranial surgery is associated with a low incidence of clinically significant pseudomeningocele, infections, leaks, and hydrocephalus.
- This technique is time-efficient and minimizes surgical incision by avoiding the need for additional tissue harvesting.
- Non-WTDC represents a viable and safe alternative for dural closure in pediatric neurosurgery.
Background:
Dural closure after intracranial procedures is considered crucial to reduce postoperative complications such as pseudomeningocele (PM), cerebrospinal fluid (CSF) leaks, hydrocephalus, and infections. However, watertight dural closure (WTDC) is often difficult to achieve, and dural substitutes often are used. We describe our experience with non-WTDC in children.
Methods:
Data were collected retrospectively. Redo and craniectomy cases were excluded. Collected data included demographics, surgical etiology, various radiologic parameters, ventricular opening, usage of drains and shunts, dural closure technique, and complications.
Results:
In total, 163 cases aged 3 months to 18.5 years (90 ± 56 months) were included. Main surgical indications were tumors (120, 74%) and epilepsy (29, 18%). In total, 122 (74%) cases were supratentorial. The ventricular system was opened in 69 (42%) cases. In 145 (89%) cases, a non-WTDC was performed. Fibrin glue was used in 22 (13%) cases. In 156 cases (96%), a dural substitute was used. One patient (0.6%) had a CSF leak. At 3 months, 20% had a radiologic PM but only 8.4% were noticed clinically. At 1 year, 7.7% had a radiologic PM but only 3% were noticed clinically. Overall, 3% needed a PM tap, and 15 patients (9%) underwent CSF diversion procedures. There were no infections. The only factor significantly associated with PM or a need for CSF surgery was an infratentorial location.
Conclusions:
Non-WTDC after cranial surgery in children was associated with a low rate of clinically significant PM, infections, leaks, and hydrocephalus. Non-WTDC is fast and reduces the need to harvest additional tissue, thus minimizing the surgical incision.
