Pulmonary hypertension secondary to arteriovenous fistula: a case report.

Pulmonary hypertension is a rare disease, associated with a significant deterioration in quality of life, usually not curable and with an ominous prognosis. It is classified into five groups according to similar pathophysiological, clinical, haemodynamic, and treatment options in each of them. However, group 5 is the least common, encompassing different types of aetiological, semiological, and management conditions. We present the case of a patient diagnosed with precapillary component pulmonary hypertension, with the finding of an arteriovenous fistula at the peripheral level. Interventional exclusion was performed, achieving remission of her disease.
