Two cases of diffuse pulmonary lymphangiomyomatosis

: We cared 2 patients with diffuse pulmonary lymphangiomyomatosis (LAM) through the perioperative period. LAM is a disease of uncertain origin and poor prognosis because of respiratory failure. Therefore, it is important to provide not only a good anesthetic care but also a good preoperative respiratory care. In the first case (a 35-yr-old woman), an open lung biopsy was performed after dyspnea and sputum had disappeared with preoperative medications of a bronchodilator and some antibiotics. In the second case (a 35-yr-old woman), oophorectomy was performed after FEV1.0% had remarkably increased with preoperative medication of a bronchodilator. Both patients did well through the perioperative period without any trouble or complications, such as pneumonia or severe hypoxemia, presumably owing to our perioperative management system.
