Pulmonary venous aneurysm: Forming a glove balloon-like shape

Introduction: 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.

Presentation of case: We report the case of PVA that continued to increase in size throughout a 17-year observational period.

Discussion and conclusion: 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.
