Physiology and Functional Pathology of the Lymphatic System with Implications for the Fontan Patient.

Contractile function of the collecting lymphatic vessels depend on smooth muscle cells, one-way valves, surrounding tissues, and regulation by the autonomic nervous system. The potentially deleterious effects of the Fontan procedure and elevated central venous pressure on lymphatic function leading to life-threatening complications are described. Presented at the 2023 ISL International Congress of Lymphology, Genoa, Italy in a special symposium on central and regional lymphatic system in health and disease.
