A limited midline skin incision (about 10 cm, range 8 to 12 cm) is made, and right-sided partial sternotomy is performed. After carefully avoiding injury to the right internal mammary artery, a transverse half sternotomy is made in the first or second intercostal space. And then, a median longitudinal sternotomy upward from the right border of the base of xiphoid process is performed. In 5 patients we achieved excellent exposure for procedure with this method, however 1 patient had necessarily conversion to a standard sternotomy because of the difficulty of aortic cross clamping. There were no operative or late death. MICS has the advantages of less pain, fewer wound infections, earlier recovery, and shorter hospitalization time. Furthermore, it is cosmetically acceptable to patients and is considered to provide patients with a high quality of life after the operation.}, pages = {426--429}, title = {当院における低侵襲小切開心臓手術(MICS)の検討}, volume = {113}, year = {1999} }
