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.
Inferior vena cava filter
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 decreases PE recurrence but are not efficacious in preventing mortality[3].
In a study group comprising of 400 patients with proximal deep-vein thrombosis, which were followed for 2 years, it was found that the initial beneficial effect of vena caval filters for the prevention of pulmonary embolism was counterbalanced by an excess of recurrent deep-vein thrombosis, without any difference in mortality[2].
Embolectomy
Embolectomy is a process of removal of an embolus via a catheter or surgically. The procedure should be used when a high risk patient present with persistent hypotension and thrombolysis has either failed or is contraindicated.
