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.
Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
An embolectomy is a procedure conducted when a blockage moves from its original site to another place in the body, thus forming an embolus. There are two methods of performing embolectomy. [15] The first method is catheter embolectomy, which involves the insertion of a catheter into the affected artery and the subsequent removal of the embolus.
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 embolism; A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency ...
Seki et al. reported the usefulness of endovascular treatment for lung cancer hemoptysis. [7] Kichang et al. reported BAE for hemoptysis in 84 lung cancer patients, and demonstrated that massive hemoptysis and cavity formation were significantly poor prognosis factors; re-hemoptysis rate was 23.8% in their follow-up period.
If these methods are not effective, surgery may be needed. Pericardial window is a surgery that is particularly in cases of cancer. [10] [28] 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.
Surgery is indicated in patients with pulmonary artery emboli that are surgically accessible. Thrombi are usually the cause of recurrent/chronic pulmonary emboli and therefore of chronic thromboembolic pulmonary hypertension (CTEPH). [2] PTE is the only definitive treatment option available for CTEPH. [3]
