An 80-year-old woman was diagnosed with a huge anterior and middle mediastinal cyst that was causing compression of the right atrium and ventricle. Computed tomography of the thorax and transthoracic echocardiography confirmed the diagnosis. She underwent complete excision of the cyst through a median sternotomy. She made an uneventful recovery and was discharged from the hospital in six days.
Why didn’t you realize the cystectomy by thoracoscopic approach instead of median sternotomy ?
