[A case of primary lung cancer associated with diffuse panbronchiolitis].

Pulmonary resection was performed for primary lung cancer of a 72-year-old patient which was associated with diffuse panbrochiolitis that required home oxygen therapy. The preoperative total pulmonary vascular resistance at rest was 564 dyne.sec.cm-5/m2, but thoracotomy and reduction surgery were possible by strict respiratory and circulatory control. The troublesome postoperative pulmonary phthisis was dealt with through extended control by means of total parenteral nutrition and use of the Heimlich valve.
