The author presents the case of a patient who was operated upon for extensive stricture of the abdominal aorta at the age of 8 years and of a height of 4'2". In the course of surgery a 12-mm diameter woven crimped vascular prosthesis was anastomosed end-to-side to the lower thoracic as well as to the infrarenal abdominal aorta to bypass the strictured aortic segment. During the following years the patient underwent four consecutive aortograms and also several surgical interventions on the visceral arteries but not on the bypass graft. The latest arteriogram taken at the age of 31 and height of 6'6" showed an approximately 15% enlongation responding with the appropriate growth of the adjacent vertebra during the years undoubtedly due to stretching, induced straightening of the "crimps," and some blunting of the angle by which the graft was attached to the thoracic aorta, an additional factor which made the course of the prosthesis adapt to body growth. The case illustrates that if crimped Dacron grafts are implanted in a growing individual in an appropriate manner, one may count that he or she will probably adapt to the natural increase of body length.
作者介绍了一名患者的病例，该患者8岁，身高4英尺2英寸，因腹主动脉广泛狭窄接受了手术。在手术过程中，一个直径12毫米的编织卷曲血管假体被端侧吻合到胸下段以及肾下腹主动脉，以绕过狭窄的主动脉段。在接下来的几年里，患者连续接受了四次主动脉造影，还对内脏动脉进行了几次手术干预，但未对旁路移植物进行干预。在患者31岁、身高6英尺6英寸时进行的最新动脉造影显示，移植物大约延长了15%，这无疑是由于多年来相邻椎体的相应生长，由拉伸引起的“卷曲”变直，以及移植物与胸主动脉连接角度的一些变钝，这是另一个使假体路径适应身体生长的因素。该病例表明，如果以适当的方式将卷曲的涤纶移植物植入正在生长的个体中，可以预期他或她可能会适应身体长度的自然增加。
