A Review of the Usefulness of Catheter-Directed Thrombolysis for Pulmonary Embolism.

Venous thromboembolic disease (VTE) is a health problem; around 10 million cases occur yearly with substantial morbidity and mortality. Those who survive may be left with long-term sequelae. Those sequelae might include chronic thromboembolic pulmonary hypertension, persistent right ventricular dysfunction, exercise intolerance, and reduced quality of life. Current PE management consists of anticoagulation alone, systemic thrombolysis, catheter-directed thrombolysis, and surgical embolectomy. The severity of patients with pulmonary embolism (PE) depends on the clinic and not exclusively on the extent of radiological or anatomical involvement. In this review, we present the main clinical and functional characteristics of patients in whom thrombotic fragmentation plus catheter-guided thrombolysis is used to manage acute PE of intermediate-high risk and torpid evolution within the first hours of admission.
