Systematic Review: The Role of Thrombolysis in Intermediate-Risk Pulmonary Embolism.

BACKGROUND: This systemic review provides practicing emergency physicians updated information about the role of thrombolysis in the treatment of intermediate-risk pulmonary embolism.

METHODS: A PubMed literature search from January 1, 2005 to December 31, 2018 was conducted and limited to human clinical trials written in English with relevant keywords. High-quality studies were identified and then underwent a structured review. Recommendations are made based on the literature review.

RESULTS: Sixty-three articles met criteria for rigorous review, of which 13 were appropriate for citation in this review. Of these 13, there were 6 prospective studies and 7 retrospective studies.

CONCLUSIONS: Thrombolysis, either catheter-directed or systemic, is a treatment option in the management of patients with intermediate-risk pulmonary embolism and a high likelihood of clinical deterioration. Each method of thrombolysis carries risks and benefits. Based on the available evidence, transfer to a facility for the purpose of catheter-directed thrombolysis is not recommended.
