One cut end of the vessel was drawn through the tube and everted over its edge, the intimal surface thus being brought to the outside. The vessel was held in this position by a ligature. The other opened cut end of the vessel was then drawn over the tube and secured again by ligature. The forceful electrochemical activity brought about by the presence of magnesium in tissues produced widespread necrosis. 2 Such anastomoses were, therefore, doomed to failure. More recently, Lord, Blakemore and Stefko 3 have introduced a vitallium® tube which is used in the same way as the original Payr tube but has the advantage of being made of a metal which does not produce tissue reaction. By use of this tube, these authors have advanced the scope of vascular surgery. 4 Their method, however,
