Regeneration of the deep cervical lymphatics--light and electron microscopic observations.

Regeneration of the lymphatic vessels following ligation of the deep cervical lymphatics was studied in 35 rabbits using both light and electron microscopes. The newly formed lymphatics were evident under the electron microscope in the first post-operative week, in which the restoration of the affected endothelial cells of the lymphatics and reaction of the free cells such as fibroblasts and macrophages were observed.
