Overlapping-plasty technique for pulmonary artery aneurysm.

Massive pulmonary artery aneurysms, while extremely rare, might require surgical intervention. Most previous cases have been repaired either by pulmonary artery plication or synthetic graft replacement. We report a case of massive pulmonary artery aneurysm that was successfully repaired using an 'overlapping-plasty' technique with the help of 3D image simulation. This specially designed procedure might be useful as a surgical option for pulmonary artery aneurysms.
