Percutaneous interventional catheter therapy for lesions of the chest and lungs.

Percutaneous, nonsurgical interventions using angiographic catheter techniques and radiologic guidance were used in the management of seven cases of various lesions of the chest and lungs. Successful catheter therapy included the embolization of a large, acquired, postinflammatory vascular malformation causing massive hemoptysis and a cavernous hemangioma of the chest wall. Sixteen pulmonary arteriovenous fistulas (one patient), an iatrogenic internal mammary artery-to-innominate vein fistula, and a persistent, postbiopsy bronchopleural fistula were successfully closed. Percutaneous drainage of a pyogenic lung abscess and the nonoperative retrieval of an intravascular foreign body that had embolized to the left pulmonary artery were also successfully achieved. Performed under local anesthesia with minimal morbidity, stress, and risk, interventional catheter therapy is remarkably cost-effective. Primary chest physicians are encouraged to consider this mode of therapy whenever applicable.
