摘要
在30具防腐的成人尸体上观测了左侧背阔肌,转位并切断背阔肌止腱后,肌瓣超过心左缘的部分长20.9cm,宽14.8cm,厚2.7mm,是心肌成形术较理想的肌瓣供体。背阔肌远侧半长度不够包卷整个心室,短缺约5.6cm,可通过松解血管神经蒂,采用“V”形连蒂心包膜瓣或截取背阔肌腱膜缝接的方式加以弥补。背阔肌过薄时,采取肌瓣折叠的方法双层修补心肌缺损或包卷心室。文中对背阔肌的剪裁和胸壁开窗位置的选择进行了讨论。
On 30 adult cadavers the left latissimus dorsi muscle was dissected.By transposition,themuscle flap may reach about 20.9cm with a width of 19.8cm and a thickness of 2.7cm.Clinicallythe muscle flap is not long enough to wrap the heart,being about 5.6cm in deficiency.However,the shortage may be made up by relaxing the neurovascular pedicie of the muscle flap,adopting aV-shaped flap of pericardium or taking up the aponeurosis of the latissimus dorsi muscle.Rele-vant questions such as how to cut the latissimus dorsi muscle and where to make the window onthe thoracic wall are discussed.
