Insights
Low-dose tissue plasminogen activator (t-PA) therapy effectively treats acute arterial and venous thrombosis in children, achieving high resolution rates with a low incidence of severe side effects.
Area of Science:
- Pediatric Thrombosis
- Thrombolytic Therapy
- Vascular Medicine
Context:
- Acute arterial and/or venous thrombosis pose significant risks in pediatric patients.
- Current treatment guidelines for pediatric thrombosis require careful consideration of efficacy and safety.
- Tissue plasminogen activator (t-PA) is a potent thrombolytic agent, but its use in children necessitates dose optimization.
Purpose:
- To evaluate the efficacy and safety of low-dose continuous intravenous tissue plasminogen activator (t-PA) in pediatric patients with acute arterial and/or venous thrombosis.
Summary:
- A prospective observational study included 18 children (1 month to 11 years) treated with low-dose t-PA (0.01-0.06 mg/kg/h).
- 94% of patients showed improvement, with 72% complete and 22% partial thrombosis resolution.
- A low incidence of severe side effects (5%) was observed, with one case of severe hemorrhage.
Impact:
- Low-dose t-PA therapy demonstrates significant efficacy in treating pediatric acute arterial and/or venous thrombosis.
- This therapeutic approach offers a favorable safety profile for pediatric patients requiring thrombolysis.
- Findings support the use of optimized low-dose t-PA regimens in managing pediatric thrombosis.
Objective:
To analyse the efficacy and side effects of low doses of tissue plasminogen activator for the treatment of acute arterial and/or venous thrombosis in children.
Patients And Methods:
Prospective observational clinical study. 18 children between 1 months and 11 years treated with low doses (0.01-0.06 mg/kg/h) of continuous intravenous thrombolytic therapy with t-PA were studied.
Results:
A total of 94% of patients improved with low doses t-PA (72% complete resolution of the thrombosis and 22% partial resolution). One patient suffered a severe haemorrhage secondary to t-Pa and had to stop the treatment. The incidence of severe side effects was low (5%)
Conclusions:
Thrombolytic therapy with low doses of t-PA (0.01-0.05 mg/kg/h) is effective in a high percentage of children with acute arterial and/or venous thrombosis and produces a relatively low frequency of side effects.
