Manejo de la tromboembolia pulmonar en niños: un consenso de expertos basado en evidencia

Pulmonary thromboembolism is rare in children, but can be life-threatening. Timely diagnosis and treatment of pulmonary thromboembolism are crucial for reducing mortality associated with pulmonary thromboembolism in children. While guidelines for pulmonary thromboembolism in adults are available, guidelines for standardized diagnosis and management of pulmonary thromboembolism in children are not. This expert consensus aims to provide recommendations for the management of pulmonary thromboembolism in children based on the current best available evidence.

Following the World Health Organization Handbook for Guideline Development, the expert panel consisted of 30 members from different clinical areas. The panel identified clinical questions through systematic reviews and expert discussions, systematically reviewed evidence on pulmonary thromboembolism in children, and evaluated the quality of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Using the GRADE Evidence to Decision Framework, the panel made recommendations, considering the effects of interventions, resource use, values and preferences, equity, acceptability, and feasibility.

The epidemiology, classification, and pathophysiology characteristics are summarized. The expert panel developed 33 recommendations addressing 20 questions related to diagnosis steps, treatment approaches such as anticoagulant therapy, thrombolysis therapy, catheter-based interventional therapy, surgical embolectomy, multidisciplinary team, and treatment of patients with comorbidities, prognosis, education, as well as follow-up. Among these, 18 are weak recommendations based on very low quality evidence, and 15 are good practice statements.

The expert panel provided recommendations for pulmonary thromboembolism in children based on available evidence, which was generally low in quality and volume. The panel urges further research on early identification and diagnosis strategies, preventive and therapeutic regimens, and long-term management for pulmonary thromboembolism.
