Long-term observations on a crimped Dacron aortic bypass graft in the growing child.

Nineteen years of clinical and angiographic observations are presented on a patient with congenital stricture of the upper abdominal aorta who underwent thoracic-to-abdominal aorta bypass grafting using a woven crimped Dacron vascular prosthesis. These observations indicate that if such a prosthesis is properly applied, i.e., attached in a proper angle and is not stretched as it is usually done in the adult, then it will be capable of gradual "lengthening" through the years and thus adapt to the needs of a growing child.
