In high risk pulmonary embolism , the main aim of therapy is to rapidly recanalize the affected pulmonary arteries with thrombolysis or embolectomy; to decrease right ventricular afterload and reverse right ventricular failure and shock, prevent chronic thromboembolic pulmonary hypertension , and decrease the recurrence risk. The first-line treatment in patients with acute high risk pulmonary embolism presenting with persistent hypotension and/or cardiogenic shock is intravenous thrombolytic therapy. However a significant proportion of patients may not be a candidate for Intravenous thrombolysis because of major contraindications. An alternative option in patients with absolute contraindications or has failed intravenous thrombolysis is surgical embolectomy , but the number of experienced tertiary care centers that can do emergency surgical embolectomy are limited. Percutaneous catheter mechanical fragmentation of proximal pulmonary arterial clots followed by injection of 200 ml saline at high pressure using power injector can be used as an alternative to intravenous thrombolytic therapy and surgical embolectomy because of their ability to rapidly recanalize occluded pulmonary blood flow.
