保留食道的心脏薄层断面解剖学研究

Thin sectional anatomy of the heart with esophagus

目的 进行保留食道的心脏薄层断面形态学研究 ,为经食道超声心动图提供断面解剖学基础。方法 用冰冻薄层切片技术将带有食道的心脏标本制作成与人体水平横断面成 0°、45°、90°、13 5°四个方向的薄层断面 ,对心脏及与其相连大血管的薄层断面结构进行观测和分析。结果 0°方向上获得了 14 0层面 ,45°方向上获得了 13 2层 ,90°方向上获得了 44层 ,13 5°方向上获得了 12 0层 ,并对四个方向主要关键层面的解剖结构进行了描述。结论 保留食道的心脏四个方向冰冻薄层断面能清晰、连续地显示心内及大血管的解剖结构与毗邻关系 。

Objective To study the sectional anatomy of the heart with esophagus to provide the sectional anatomic data for transesophageal echocardiography(TEE). Methods Hearts with esophaguses were sectioned at the angles of 0°, 45°, 90° and 135° relative to the human cross section by frozen section technique. The sectional anatomic structures were observed and analyzed. Results A total of 140, 130, 44 and 130 slices were obtained at the angles of 0°, 45°, 90° and 135°, respectively. The anatomic structures of the key slices were described. Conclusion The thin sections of the heart can clearly display the anatomical details of the inner structures of the heart, which may play an important role in the clinical application of TEE.
