Pulmonary thromboendarterectomy

Pulmonary Thromboendarterectomy is a surgical procedure that is performed to remove organized clotted blood (thrombi) from the pulmonary arteries. This procedure is typically performed on patients who have been diagnosed with Chronic Thromboembolic Pulmonary Hypertension (CTEPH).

Overview

Pulmonary Thromboendarterectomy (PTE) is a complex surgical procedure that requires a highly skilled surgical team. The procedure involves the removal of thrombi from the pulmonary arteries, which can improve blood flow to the lungs and reduce pulmonary hypertension.

Indications

PTE is indicated for patients with Chronic Thromboembolic Pulmonary Hypertension (CTEPH) who have not responded to medical therapy. CTEPH is a condition characterized by the presence of chronic, organized thrombi in the pulmonary arteries that obstruct blood flow and lead to pulmonary hypertension.

Procedure

During a PTE, the patient is placed on cardiopulmonary bypass and the body is cooled to reduce metabolic demand. The surgeon then opens the pulmonary arteries and removes the thrombi. The procedure is performed under deep hypothermic circulatory arrest to protect the brain and other vital organs.

Risks and Complications

As with any major surgery, PTE carries risks and potential complications. These may include bleeding, infection, stroke, and death. Specific to PTE, there is a risk of reperfusion injury, which can lead to acute respiratory distress syndrome (ARDS).

Prognosis

The prognosis following PTE is generally good, with many patients experiencing significant improvement in symptoms and quality of life. However, the success of the procedure depends on a variety of factors, including the extent of the disease and the patient's overall health.
