Abstract:
Chylothorax is defined as an effusion of lymph in the pleural cavity. In the neonate both congenital and traumatic (iatrogenic) forms exist. Birth asphyxia and respiratory insufficiency are major symptoms of congenital chylothorax, requiring resuscitation and artificial ventilation. Antenatal diagnosis by ultrasound allows early therapeutic intervention such as ventilatory support and drainage of chylous fluid immediately after birth. Traumatic chylothorax is mainly seen after intrathoracic surgery. Treatment primarily consists of continuous or intermittent drainage of chyle with replacement of fluid-, electrolyte-, and protein losses and parenteral nutrition. Introduction of oral feeding is considered only after a substantial period without chyle production in the pleural cavity and consists of a medium-chain triglyceride containing formula. In a minority of cases surgical intervention is necessary.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
