In massive and submassive PE, dysfunction of the right side of the heart may be seen on echocardiography, an indication that the pulmonary artery is severely obstructed and the right ventricle, a low-pressure pump, is unable to match the pressure.
In certain patients with more severe forms of PE (massive or submassive), sonothrombolysis can improve cardiopulmonary function and reduce the bleeding risk that is accompanied by systemic thrombolysis. [8]
Massive pulmonary embolism requires thrombolysis or embolectomy. Thrombolysis can be systemic via IV alteplase (tPA) or catheter-directed. tPA works to break up the clot. A major risk of tPA is bleeding. Thus, patients must be assessed for their risk of bleeding and contraindications.
pulmonary embolism (PE) [3] [4] [5] BB00. VTE is a common cardiovascular disorder with significant morbidity and mortality. [3] [4] [5] VTE can present with various symptoms, such as painful leg swelling, chest pain, dyspnea, hemoptysis, syncope, and even death, depending on the location and extent of the thrombus.
This carries a risk of bleeding and is therefore reserved for those who have a form of thrombosis that may cause major complications. In pulmonary embolism, this applies in situations where heart function is compromised due to lack of blood flow through the lungs ("massive" or "high risk" pulmonary embolism), leading to low blood pressure. [42]
Surgical embolectomy for massive pulmonary embolism (PE) has become a rare procedure and is often viewed as a last resort. Thrombolytic therapy has become the treatment of choice. [1] Surgical or catheter embolectomy is a procedure performed in patients with pulmonary embolism, which is a blockage of an artery in the lung caused by a blood clot.
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Arterial occlusion can be classified into three types based on etiology: embolism, thrombosis, and atherosclerosis. These three types of occlusion underlie various common conditions, including coronary artery disease , [ 4 ] peripheral artery disease , [ 5 ] and pulmonary embolism , [ 6 ] which may be prevented by lowering risk factors.
