Surgical pulmonary embolectomy and catheter-based therapies for acute pulmonary embolism: A contemporary systematic review.
Mortality in acute pulmonary embolism (PE) is believed to be principally due to the subgroup of PEs that are massive. Systemic thrombolysis is the therapeutic mainstay for acute massive PE, despite evidence suggesting limited survival benefits. Both catheter-based therapies (CBT) and surgical pulmonary embolectomy (SE) are well-accepted alternatives to treat acute PE. However, the comparative effectiveness of these approaches is difficult to study. We conducted a systematic review of CBT and SE for acute PE. ⋯ Both CBT and SE were associated with satisfactory published outcomes. SE is associated with greater absolute postprocedure mortality than CBT, but has been undertaken in more critically ill populations. The markedly higher incidence of CPR in SE accounts for the differential mortality between the patients undergoing SE and those undergoing CBT. Decision making with respect to best therapy must take into account potential needs for periprocedure artificial mechanical right ventricle and lung support, institutional experience and outcomes, anticipated therapeutic efficacy and benefit, and approach-specific risks.
