title: Trepopnea due to recurrent lung cancer.
abstract: Trepopnea is a condition whereby breathing may be comfortable in one position but difficult or labored in another. A unique case with trepopnea due to recurrent lung cancer with right main pulmonary artery stenosis and left main bronchus obstruction is presented. The patient had developed trepopnea 3 months earlier, but developed orthopnea shortly before he was admitted to our hospital. An emergent wall stent implantation was performed via the right femoral vein in the sitting position with the patient's leg stretched out. The symptoms and respiratory function improved after stent implantation.
