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.
Typical specimen harvested during the surgical procedure of pulmonary endarterectomy in a patient with chronic thromboembolic pulmonary hypertension. Pulmonary endarterectomy (PEA) is the gold standard treatment for suitable CTEPH patients. Operability of patients with CTEPH is determined by multiple factors among which surgical accessibility ...
In cases where a significant artery is totally blocked, it may be possible to remove the plaque and use the same hole in the artery to perform an anastomosis. This technique is called endarterectomy and is usually performed at the right coronary system. [26] Re-operations of CABG (another CABG operation after a previous one) pose difficulties.
Stuart William Jamieson FRCS (born 1947) is a British cardiothoracic surgeon, specialising in pulmonary thromboendarterectomy (PTE), a surgical procedure performed to remove organized clotted blood from pulmonary arteries in people with chronic thromboembolic pulmonary hypertension (CTEPH).
Endarterectomy is a surgical procedure to remove the atheromatous plaque material, or blockage, in the lining of an artery constricted by the buildup of deposits. It is carried out by separating the plaque from the arterial wall.
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.
If both pulmonary arteries are not mobilized adequately, they can become stretched, leading to pulmonic stenosis. [ 2 ] Commonly, the maneuver is used during an arterial switch procedure (in which the pulmonary artery and aorta switch positions) or in surgery to correct absent pulmonary valve syndrome .
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.
