低侵襲大動脈弁置換術後に生じた肋間肺ヘルニア

Intercostal Lung Hernia after Minimally Invasive Cardiac Surgery （MICS）-Aortic Valve Replacement （AVR） Surgery

肋間肺ヘルニアは肺実質が正常な胸腔内区域を越えて突出するまれな疾患である．われわれは，低侵襲心臓手術（minimally invasive cardiac surgery：MICS）による大動脈弁置換術（aortic valve replacement：AVR）後に発症した肋間肺ヘルニアの1例を経験したので報告する．

A 51 years old male had underwent aortic valve replacement （AVR） by minimally invasive cardiac surgery （MICS） for aortic regurgitation. About one year after the surgery, bulging of the wound and pain appeared. His chest computed tomography showed an image of the right upper lobe protruding from the thoracic cavity through the right second intercostal space, and the patient was diagnosed as having an intercostal lung hernia and the surgical treatment was performed using a unsintered hydroxyapatite and poly-L-lactide （u-HA/PLLA） mesh plate and monofilament polypropylene （PP） mesh. Postoperative course was uneventful without any evidence of recurrence.
