[Frame-mounted anastomosis of veins using a microsurgical technique and demineralized tubular allobone]

The experimental-morphological analysis covers the results of 62 operations for establishment of major vein anastomosis. In three series of experiments microsurgical suturing was used, while the control series employed the techniques of general surgery. In the microsurgery group, the best outcome (100 percent patency without anticoagulant administration) was achieved in cases when the venous anastomosis was protected by the demineralized tubular bone. Good outcomes were seen in cases with application of the original technique of mounting the venous anastomosis on rings of tubular bone. The advantages of microsurgical frame-mounted suturing of major veins over the general surgical techniques are demonstrated.
