title: Pulmonary venous aneurysm: Forming a glove balloon-like shape.
abstract: BACKGROUND
  Pulmonary venous aneurysm (PVA) is a candidate for surgery because of the risk of rupture and continued growth even if the patient does not develop mitral valve disorders.
  
  
  METHODS
  We report the case of PVA that continued to increase in size throughout a 17-year observational period.
  
  
  CONCLUSIONS
  The location and form of the aneurysm are important to consider when choosing the surgical approach. If the aneurysm forms a "glove balloon-like shape," lobectomy is necessary because end-to-end anastomosis is difficult to perform in such cases.
