title: Cervical venous anastomoses of pulmonary lymphatic vessels.
abstract: The aim of this study was to describe in detail the anastomoses between the pulmonary lymphatic vessels and the veins of the neck so as to better understand their role in certain aspects of thoracic surgery. The lymphatic vessels of 687 pulmonary segments in 360 cadavers were injected. A detailed study of the proximal end of the right paratracheal, right tracheo-esophageal, left preaortocarotid and left recurrent lymph node chains was undertaken. The results showed the absence of any major right lymphatic "vein". There were, however, many lymphatic arches draining into the jugulo-subclavian confluence ipsilaterally, and, in 10 to 15% of cases, contralaterally as well. The intertracheobronchial lymph nodes also drained into the venous confluence of the neck via direct lymphatic vessels, without lymph node relays. Finally, the left mediastinal lymph node chains were frequently found to drain into the arch of the thoracic duct (40% of cases), and reflux due to valvular incompetence at this level may account for chylous pericarditis and some cases of chylothorax after surgery.
