✦ Synopsis

The repercussions on the venous wall of the creation of 20 artero-venous anastomoses (AVA) between the femoral artery and vein of the rat have been evaluated. The rats were killed 7, 15, 30, and 90 days after AVA, and AVAs were examined by optical microscopy and by scanning electronic microscopy. Deposits of whitish material that nearly completely occluded the venous lumen were seen, especially in the group studied longer than 90 days. These venous wall lesions, which resemble arteriosclerotic lesions, must be attributed to the new hemodynamic situation created by the AVA. The implications of such findings for the long-term validity of venous graft in vascular microsurgery and the long-term patency of the AVA in hemodialyzed children are discussed.

A new technique for easier end-to-side anastomosis of veins is presented. By applying a few traction sutures to the edge of the venotomy and tenting the venous wall, thereby keeping the venotomy open, end-to-side anastomosis of the vein can be easily performed.
