Preemptive ligation of the thoracic duct (TD) is occasionally performed during cardiothoracic procedures to prevent chylothorax. Landmarks for localizing this structure are thus important to the surgeon during such procedures. One historically used area for identifying this structure in the thorax is Poirier's triangle. The present paper aimed to investigate the relationship of the TD to Poirier's triangle.
We evaluated the use of this geometric area in localizing the TD in 35 adult cadavers.
Poirier's triangle was found in all specimens, but the TD was found within the confines of Poirier's triangle in only 17 specimens (45.7%). When not identified in Poirier's triangle, the regional TD was often (28.6%) seen in the interval between the proximal left subclavian and left common carotid arteries.
These data may be of use to the surgeon when identifying the proximal TD within the thorax.
在心胸外科手术中，有时会进行胸导管（TD）的预防性结扎以预防乳糜胸。因此，在此类手术中，该结构定位的标志对外科医生很重要。胸部中一个历史上用于识别该结构的区域是普瓦捷三角。本文旨在研究胸导管与普瓦捷三角的关系。
我们评估了这个几何区域在35具成年尸体中用于定位胸导管的情况。
在所有标本中均发现了普瓦捷三角，但仅在17个标本（45.7%）中，胸导管位于普瓦捷三角范围内。当在普瓦捷三角中未识别到时，局部胸导管常在（28.6%）左锁骨下动脉近端与左颈总动脉之间的间隙中见到。
这些数据对外科医生在胸腔内识别胸导管近端时可能有用。
