Overview
Surgical management of acute pulmonary embolism (pulmonary thrombectomy) is uncommon and has largely been abandoned because of poor long-term outcomes. However, recently, it has gone through a resurgence with the revision of the surgical technique and is thought to benefit selected patients.[1] Chronic pulmonary embolism leading to pulmonary hypertension (known as chronic thromboembolic hypertension) is treated with a surgical procedure known as a pulmonary thromboendarterectomy.
Surgery
Embolectomy
Embolectomy is the process of removing an embolus surgically or with a catheter. The procedure should be used when a high risk patient presents with persistent hypotension and thrombolysis has either failed or is contraindicated.

Inferior Vena Cava Filter
An inferior vena cava filter] is a medical device that is implanted into the inferior vena cava to prevent pulmonary emboli (PEs).
IVC filters are used in the following cases:
- Anticoagulation is contraindicated
- Failure of anticoagulation
- Anticoagulation complication in patients who have a venous thromboembolism disease.
- Prophylactic measures for patients with a high risk of pulmonary embolism.
If anticoagulant therapy is contraindicated and/or ineffective, an inferior vena cava filter should be implanted.[2] It provides a filter in the inferior vena cava, allowing blood to pass through, while preventing large emboli from traveling from the lower extremities to the lung. IVC filters decrease PE recurrence but are not efficacious in preventing mortality.[3].
In a study group comprised of 400 patients with proximal deep-vein thrombosis, who were followed for 2 years, it was found that the initial beneficial effect of vena cava filters was counterbalanced by an excess of recurrent deep-vein thromboses. No difference in mortality was noted.[2]
Angioplasty
Angioplasty is the mechanical widening of a narrowed or totally obstructed blood vessel. These obstructions are often caused by atherosclerosis. The term angioplasty is a portmanteau of the words angio (from the Latin/Greek word meaning "vessel") and plasticos (Greek: "fit for moulding"). Angioplasty has come to include all manner of vascular interventions typically performed in a minimally invasive or percutaneous method.
2011 ACC/AHA Guidelines- Recommendations for Catheter Embolectomy and Fragmentation (DO NOT EDIT)[4]
