ABSTRACT
BACKGROUND: The optimal therapy for submassive pulmonary embolism remains in question. The following meta-analysis compiles the current evidence comparing catheter-directed thrombolysis (CDT) versus systemic anticoagulation (SA).
METHODS: An electronic search through PubMed and Google scholar revealed studies comparing CDT versus SA in terms of mortality and major bleeding events. 30-day, 90-day, and 1-year mortality results were analyzed.
RESULTS: Six studies were included in the meta-analysis. Thirty-day and one-year mortality were less with CDT compared to SA (OR 0.27 [CI 0.11-0.67]; OR 0.50 [CI 0.28-0.89]). Ninety-day mortality was similar between the two methods (OR 0.57 [CI 0.17-1.92]). Compilation of all studies reporting at least greater than 30-day mortality revealed less mortality with CDT (OR 0.51 [0.30-0.86]). Major bleeding was similar between the two treatments (OR 1.63 [CI 0.63-4.20]).
CONCLUSION: CDT has less 30-day and 1-year mortality with equivalent rates of major bleeding compared to SA for treatment of submassive pulmonary embolism.
