The thrombus chronic embolic pulmonary hypertension (CTEPH) and pulmonary thrombosis, a condition characterized by a disproportionately high pressure in the arteries of the lungs. This disease can cause the heart to suffer great distress and, if not treated early, involves serious problems, including death. The origin of pulmonary hypertension is the narrowing of blood vessels in the lungs, this happens when the pressure is accumulated by the difficulty of transporting such blood vessels. Currently, the indicated treatments for this disease: pulmonary thromboendarterectomy, a surgical technique that involves removing fatty plaques or blockages of the vessels supplying the lungs, but is contraindicated in patients with severe obstructive or restrictive lung disease; lung transplantation, indicated for those patients who are not eligible for pulmonary endarterectomy surgery.
