Proximal pulmonary artery embolization for recurrent hemoptysis after bronchial artery embolization.

Proximal pulmonary artery (PA) embolization is a dramatic interventional radiology procedure performed to control recurrent, life-threatening hemoptysis. Distal PA embolization procedures are commonly performed, and preoperative proximal PA embolization procedures have been reported, but to the best of our knowledge there has not been a reported case of a proximal PA embolization to treat hemoptysis. Here, we present a case of a complete proximal PA embolization that effectively resolved recurrent hemoptysis in a patient with a lung tumor following a failed bronchial artery embolization.

Copper Deficiency Myeloneuropathy in Autoimmune Disease.

Copper deficiency is a rare and potentially treatable cause of myeloneuropathy. The most common causes of acquired copper deficiency include malabsorption following gastric surgery and excessive zinc supplementation. Clinical manifestations can be localized to the dorsal spinal cord and present similarly to those that characterize classic vitamin B12 deficiency.
