血管吻合技术具有操作简单、吻合速度快、内膜对合整齐、腔内无异物、血管畅通率高等优点 ,在国内外得到广泛的应用。我们于 1995～ 2 0 0 0年间对 15例下颌骨较大的缺损用带血管蒂的髂骨移植 ,以钛环钉吻合血管 ,术后血流通畅 ,13例移植骨完全成活 ,手术时间较传统吻合法明显 Vascular anastomosis technique has the advantages of simple operation, fast anastomosis, intima-media alignment, no foreign body in the cavity and high blood-flow rate, which are widely used both at home and abroad. From 1995 to 2000, 15 cases with larger mandibular defects were treated with iliac graft with vascularized pedicle screw, and the blood vessels were unobstructed by titanium ring nail. The postoperative blood flow was unobstructed, and 13 cases of bone graft survived completely. The operation time was longer Traditional anastomosis obvious
