Incidence and Risk Model of Post-Traumatic Hydrocephalus in Patients with Traumatic Brain Injury

Area of Science:

• Neurosurgery
• Trauma Surgery
• Neurology

Background:

• Post-traumatic hydrocephalus (PTH) is a recognized complication following traumatic brain injury (TBI).
• Early identification and management of PTH are critical for optimizing patient outcomes.
• Understanding the incidence and risk factors for PTH is essential for developing effective clinical strategies.

Purpose of the Study:

• To determine the incidence of PTH in a large cohort of TBI patients.
• To identify significant risk factors associated with the development of PTH.
• To analyze the timing of PTH diagnosis relative to hospital discharge.

Main Methods:

• Retrospective cohort study of 7,473 TBI patients admitted between 2009 and 2015.
• Survival analysis incorporating death as a competing risk to evaluate risk factors for PTH.
• Assessment of demographic, perioperative, and in-hospital data.

Main Results:

• The overall incidence of PTH requiring shunt surgery was 0.94%, with an adjusted cumulative incidence of 0.99%.
• Significant risk factors for PTH included craniectomy (HR 11.53), venous sinus injury (HR 4.13), and age ≤5 years.
• A higher Glasgow Coma Score (GCS > 13) was protective (HR 0.50), and 60% of shunt surgeries occurred post-discharge.

Conclusions:

• PTH incidence in TBI is low but significant, with specific surgical and injury-related factors increasing risk.
• The majority of PTH cases are diagnosed after hospital discharge, highlighting the need for extended monitoring.
• Multidisciplinary vigilance and close follow-up are crucial for preventing long-term morbidity and disability in TBI survivors.
