Abstract
CONSIDERABLE knowledge has been accumulated concerning the healing of arteries repaired by suture, the technical features of the operative procedure which favor a successful result and the influence of certain local pathologic processes on the outcome. Little or nothing is known about the strength of the sutured artery or the increase in circumference of the line of anastomosis during the period of body growth. The experiments herein recorded were carried out in an effort to answer the following questions: Does the artery repaired by end to end anastomosis have great or little resistance to disruption when tension is made on the suture line by direct pull? Does the repaired artery have great or little resistance to bursting from intraluminal pressure? Is there a curve of arterial healing similar to those established for the healing of other tissues? Does the line of suture in the anastomosed artery increase in size with
