Further Outpatient Care
See the list below:
Patients or caregivers should seek immediate medical evaluation and attention if the signs and symptoms of PTH return.
Further Inpatient Care
See the list below:
Patients typically make rapid gains in the first 1-2 weeks following shunt placement for PTH; therefore, rehabilitation may be beneficial as PTH resolves.
Because shunts may malfunction, physicians should monitor patients for the signs and symptoms of PTH.
See the list below:
The possible complications of PTH include the following:
- Cerebral herniation
- Risk of aspiration as a result of dysphagia
- Increased risk of falls
- Inability to benefit from rehabilitation
Groswasser found that in patients who developed communicating hydrocephalus following a TBI, the duration of coma was longer and the incidence and severity of behavioral problems was greater. Furthermore, in patients with a TBI and communicating hydrocephalus, the rate at which these individuals returned to their previous occupation was lower than it was in patients with a TBI but no PTH.
Patients typically do well after the placement of a shunt for PTH. Tribl and Oder's study indicated that the best predictor of outcome following shunting is the patient's pre-operative status. The authors' results also indicated that age at time of injury does not influence outcome.
Similarly, Kim and colleagues found evidence that symptomatic improvement after pre-operative lumbar drainage provides a strong indication of the results of shunt placement and that age and sex seems to have no impact on outcome.
Shunts may malfunction and require revision or replacement; therefore, careful monitoring for the signs and symptoms of functional decline is important for the physiatrist and for caretakers.
A study from Denmark indicated that in patients undergoing inpatient rehabilitation for TBI, the occurrence of PTH does not affect rehabilitation outcome or the extent of disability at discharge but does prolong the patient’s stay. The study involved 417 patients with severe TBI, with multiple regression analysis used to evaluate the effects of PTH on rehabilitation. PTH was found to increase patients’ rehabilitation stay by nearly 3 weeks.

Patients and caregivers need to be educated about symptoms that might suggest shunt failure and should be instructed as to when medical evaluation should be sought.
