title: [Recurrent hemoptysis due to systemic-pulmonary anastomosis of the inferior right phrenic artery. Treatment by percutaneous embolization].
abstract: Systemic-pulmonary-artery anastomoses resulting in a left-to-right shunt, regardless of the etiology, the anastomosis resulting shunt produces increased oxygen saturation in the ipsilateral pulmonary artery. They are radiologically seen sporadically in patients with hemoptisis, being main causes: traumatic, inflammatory or congenital, many times keeps etiology unknown. We present the case of a 33 year-old male with recurrent hemoptisis without etiology defined; his chest x-ray was reported as normal. The study was completed with broncoscopy, HRCT and selective arteriography, allowed diagnosis of shunt diafragmatic lower right artery with pulmonary artery. Finally our patient was treated by percutaneous transcatheter embolization.
