Insights
Hydrocephalus (HC) shunt revision rates vary by cause, with early revisions common in stable conditions like post-hemorrhagic and post-traumatic HC, but late revisions more frequent in dynamic conditions such as in children and tumor patients. Data does not support HC being transient.
Area of Science:
- Neurosurgery
- Pediatric Neurosurgery
- Neurology
Background:
- Hydrocephalus (HC) presents with diverse etiologies and requires tailored therapeutic approaches.
- Shunt revision rates are expected to differ based on the underlying cause of HC.
- While HC is often a lifelong condition, a lack of late shunt revisions suggests potential for superfluous shunts in some cases.
Purpose of the Study:
- To analyze shunt revision patterns in hydrocephalus patients based on etiology.
- To determine if hydrocephalus can be considered a transient condition based on shunt revision data.
Main Methods:
- A retrospective analysis of a 10-year surgical database.
- Inclusion of all newly inserted shunt systems and subsequent revisions.
- Categorization of patients by hydrocephalus etiology.
Main Results:
- Overall shunt revision rate was 39.5% in 260 eligible patients over 4.5 years.
- Early revisions (within 6 months) were high in Normal Pressure Hydrocephalus (NPH), post-hemorrhagic, and post-traumatic HC (55.6%-75%).
- Children and tumor-related HC showed lower early revision rates (38.1% and 20%, respectively), but predominantly late revisions.
Conclusions:
- Two distinct shunt revision patterns emerged: early for stable etiologies (NPH, post-hemorrhagic, post-traumatic) and late for dynamic etiologies (children, tumors).
- The data does not support the hypothesis that hydrocephalus is transient due to a lack of late shunt revisions.
Introduction:
Hydrocephalus (HC) occurs due to multiple origins. Time course and dynamic of HC and its therapies differ between underlying pathologies. Different revision rates due to the type of HC are expected. Though hydrocephalus is known to be a life time condition, the lack of shunt malfunction years or decades after initial shunt insertion raises the hope of a superfluous shunt.
Methods:
We conducted a retrospective survey of our OR-database during a 10 year period. All newly inserted shunt systems and subsequent shunt revisions are recorded according to quantity and time point. All patients were subdivided according their aetiology of HC.
Results:
260 patients were eligible with a follow-up of 4.5 years. Subgroups were: 90 patients with NPH, 76 patients with posthaemorrhagic and 16 patients had posttraumatic HC. 22 received a shunt as a consequence of a tumour, 41 were children and 15 for other causes. Overall revision rate was 39.5%. During the first 6 months 55.6%, 57.9% and 75% of patients with NPH, posthaemorrhagic and posttraumatic HC had revisions. In contrast only 38.1% of children and 20% of tumour cases required early revision.
Conclusion:
Two different patterns of revision are evident: mainly early revisions in morphologically stable diseases such as posthaemorrhagic, posttraumatic and NPH and predominantly late revisions in changing organisms such as children and tumour patients. The conception HC may be transient because of a lack of late revisions cannot be supported by this data.
