CEA
Pronunciation: C-E-A
Also written as: CEA — Cultured Epithelial Autograft
Cultured Epithelial Autograft - laboratory-grown skin cells from the patient's own tissue used for burn wound coverage.
Full Definition
Cultured Epithelial Autograft (CEA) is a sophisticated burn treatment technique involving the laboratory cultivation of a patient's own epidermal cells to create large sheets of skin for transplantation. The process begins with a small skin biopsy from the patient, from which keratinocytes are isolated and grown in tissue culture over several weeks. This technology allows for massive expansion of the patient's own skin cells, potentially creating enough tissue to cover large burn areas from a small initial sample. CEA is particularly valuable for patients with extensive burns where donor sites for traditional grafts are limited. However, CEA grafts are fragile and require specialized handling and post-operative care.
Usage
Usage note: Use all capitals for the abbreviation; distinguish from carcinoembryonic antigen (same abbreviation, different field).
