Insights
This study explored streptokinase treatment for posthaemorrhagic ventricular dilatation (PHVD) in infants. Intraventricular streptokinase infusion successfully restored cerebrospinal fluid pathways, avoiding shunt surgery in most cases.
Area of Science:
- Neonatal Neurology
- Pediatric Neurosurgery
- Intracranial Hemorrhage Management
Background:
- Posthaemorrhagic ventricular dilatation (PHVD) often results from intraventricular hemorrhage obstructing cerebrospinal fluid (CSF) reabsorption.
- Progressive PHVD necessitates surgical shunt placement in over 60% of affected infants, with existing treatments having significant drawbacks.
Purpose of the Study:
- To investigate the efficacy of intraventricular streptokinase infusion as a fibrinolytic therapy to restore CSF reabsorption pathways.
- To determine if streptokinase treatment can prevent the need for surgical shunt placement in infants with progressive PHVD.
Main Methods:
- A pilot study involving nine preterm infants with progressive PHVD.
- Treatment consisted of intraventricular infusion of streptokinase over 12-72 hours.
- Assessed fibrinolytic activity in ventricular and spinal fluid, and monitored for shunt requirement, infection, and rebleeding.
Main Results:
- All nine infants survived the treatment.
- Only one infant required surgical shunting, indicating high efficacy.
- A 200% increase in fibrinolytic activity was observed in both ventricular and spinal fluid.
- No infections occurred; minor rebleeding in one case was not clinically significant.
Conclusions:
- Intraventricular streptokinase infusion is a promising, direct therapeutic approach for the underlying pathology of PHVD.
- This fibrinolytic strategy effectively restores CSF pathways and significantly reduces the need for shunt surgery in infants.
- The treatment demonstrated safety and efficacy in this pilot study, offering a potential alternative to invasive procedures.
Abstract:
Posthaemorrhagic ventricular dilatation (PHVD) is thought to be due to clots from intraventricular haemorrhage obstructing cerebrospinal fluid pathways involved in reabsorption. Over 60% of infants with progressive PHVD have gone on to require surgical shunt placement. Previous treatments all have major problems. The object of this pilot study was to achieve enough fibrinolysis to restore pathways of cerebrospinal fluid reabsorption and so avoid shunt surgery. Nine preterm infants with progressive PHVD were treated with intraventricular infusion of streptokinase for 12-72 hours. All the infants survived and surgical shunting was required in only one case. A 200% increase in fibrinolytic activity was demonstrated in both ventricular and spinal fluid during streptokinase treatment. There were no cases of infection. Minor rebleeding occurred in one case and was not a serious problem. This represents the first direct therapeutic approach to the pathology of PHVD.
