Overview
In thoracic surgery, a pulmonary thrombectomy, is an emergency procedure that removes clotted blood (thrombus) from the pulmonary arteries. Embolectomy can be done via a catheter or surgically.
Types
- Catheter embolectomy
- Rheolytic embolectomy
- Rotational embolectomy
- Surgical embolectomy
Description
Mechanical thrombectomies can be
- Surgical (surgical thrombectomy)
- Percutaneous (percutaneous thrombectomy) [1].
Surgical thrombectomies were once popular but were abandoned because of poor long-term outcomes. Recently, in selected patients, they have gone through a resurgence with the revision of the surgical technique.[2]
Relation to PTE
Pulmonary thrombectomies and pulmonary thromboendarterectomies (PTEs) are both operations that remove thrombus. Aside from this similarity they differ in many ways.
- PTEs are done non-emergently whilst pulmonary thrombectomies are typically done as an emergency procedure.
- PTEs typically are done using hypothermia and full cardiac arrest.
- PTEs are done for chronic pulmonary embolism, thrombectomies for severe acute pulmonary embolism.
- PTEs are generally considered a very effective treatment, surgical thrombectomies are an area of some controversy and their effectiveness a matter of some debate in the medical community.
