左侧胸骨旁切口的评价

目的 系统评价左侧胸骨旁切口，为临床使用提供参考。方法 随机选取福尔马林保存成人尸体6具，模拟不同平面的上半部分胸骨劈开切口，从显露效果、美容效果和损伤程度三方面对该切口进行评价。结果 左侧胸骨旁切口的皮肤切口较为隐蔽，长度较短，美容效果较好；由于术野较小，损伤结构不多，损伤较小；合理选择切口水平，左心各结构可依次被显路。结论 左侧胸骨旁切口是一种较美观、损伤小的小切口，该切口对心脏左侧各结构，如肺动脉干、肺动脉瓣、右室流出道、左冠状动脉主干等依次显露，对心脏右侧各结构显露不佳。

Evaluation of left parasternal approach for cardiac surgery.]

OBJECTIVE: To provide a systemic evaluation of left parasternal approach (LPSA) for its clinical application. METHODS: LPSA was performed in 6 randomly-chosen formalin-preserved adult cadavers and the excisions were evaluated in external light of the external appearance, extent of traumatic injury and exposure of the structures in the thoracic cavity. RESULTS: LPSA left only short and less obvious skin incisions, thus causing minimal exterior appearance impairment. With a small operative field and only a few structures injured by this approach, LPSA had acceptable traumatic lesions and when the adequate intercostal level was chosen, the lateral structures on the left of the heart could be well exposed. CONCLUSION: LPSA is less invasive and involves acceptable external appearance impairment. Though satisfactory in exposing the structures on the left of the heart, LPSA can not properly expose the structures on the right side.
