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.
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream . [6] Symptoms of a PE may include shortness of breath , chest pain particularly upon breathing in, and coughing up blood . [ 1 ]
In thoracic surgery, a pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy (PEA), [1] is an operation that removes organized clotted blood from the pulmonary arteries, which supply blood to the lungs.
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 ...
Pulmonary thrombectomies and pulmonary thromboendarterectomies (PTEs) are both operations that remove thrombus. Aside from this similarity they differ in many ways. PTEs are done on a nonemergency basis while pulmonary thrombectomies are typically done as an emergency procedure. PTEs typically are done using hypothermia and full cardiac arrest.
A right-sided acute deep vein thrombosis (to the left in the image). The leg is swollen and red due to venous outflow obstruction. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous thromboembolism (VTE).
Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung. In people with a "shunt" (a connection between the pulmonary and systemic circulation), either in the heart or in the lung, a venous clot can also end up in the arteries and cause arterial embolism.

The non-hemoptysis survival rates at 1, 3, and 5 years for PVA were 77%, 68%, and 66% respectively, and 88%, 85%, and 83% for NBCA, higher in the NBCA group (P = .01). NBCA was associated with fewer complications and better outcomes than previously reported for PVA. Woo S, Yoon CJ, Chung JW, et al. Radiology. 2013 Nov;269(2):594-602. PMID 23801773.
