Abstract:

Pulmonary endarterectomy (PTE) is a complex surgical procedure that provides functional and haemodynamic improvement in patients with chronic thromboembolic pulmonary hypertension. The use of PTE procedures is increasing all over the world and by getting a high level of surgical expertise; therefore, mortality rates are gradually decreasing day by day. Initially, operative mortality rates were high with a range of approximately 4%-24%. These rates have substantially decreased all over the world. PTE is a surgical technique that aims to remove unresolved thromboembolic material that obstructs the pulmonary arteries. Significant and persistent decreases in pulmonary artery pressures and pulmonary vascular resistance are observed in patients with chronic thromboembolic pulmonary hypertension after the surgery. Nowadays, this operation is offered to those patients who were considered to be inoperable in the past.
