左心耳的结构与血栓形成的相关性研究进展

Advance in applied anatomy of structure and thrombosis in the left atrial appendage

左心耳位于左心房游离壁,具有独特的组织结构、生理功能、血流动力学特点。左心耳毗邻解剖结构较多,变异性较大,与血栓形成关系密切。文中综述了左心耳的形态结构、机能特点及其与血栓形成的相关性,对减少介入手术中潜在的并发症风险和临床误诊,具有重要临床意义。

Left atrial appendage （LAA） arises from the left atrial free wall. It is the remnant of the original embryonic LA, distinct from the rest of the left atrium. It has a unique anatomical structure, physiological function, hemodynamic characteristics. LAA has complex surrounding structures, great variability, and close relation with thrombosis. This paper reviews the morphological and functional characteristics of LAA. Familiar with adjacent relationship of LAA and correlation between LAA and thrombus formation has important clinical significance that can reduce the risk of postoperative complications in interventional procedures, the incidence of cardioembolic stroke, the clinical misdiagnosis on LAA thrombosis.
