摘要
目的用数字减影血管造影（ＤＳＡ）评价带旋髂深血管骨膜移植治疗股骨头坏死后血运重建情况。方法对２０例术前、１４例术后股骨头坏死病人用ＤＳＡ检查，动态观察血管通畅情况。结果术前见旋髂深动脉位置恒定，无缺如者，末端有３～７支分布于髂骨嵴部。术后３周，见旋髂深动脉较术前粗，流速基本相同，末端在股骨头内分布均匀，呈“鸟窝”样改变。术后３个月血管较术前仍稍粗，流速稍快，末端头内呈团状，“鸟窝”样改变增大，微细血管分布达软骨下区，结论用ＤＳＡ成功地观察到股骨头坏死术后血运重建良好。该检查操作简单、创伤小、安全可靠、图像清晰。
Objective To use digital subtraction angiography (DSA) to evaluate blood supply reestablishment after the treatment of the avascular necrosis of femoral head (ANFH) by using the vascularized iliac periosteum with deep iliac circumflex artery (DICA) and vein pedicle.Methods Seldinger method was used to puncture femoral artery interpate of 20 patients with pre and postoperative ANFH. 6.5F Cobrn conduct was optionally used and put directly into DICA and then contrast medium, was injected for observation of blood vessel.Results Before operation, the position of DICA was found constant, 3 to 7 branches termity among the crest part of iliac bone. Three weekes after operation, DICA was found wider than that before operation, but the blood flow speed remained almost the same and its termity was distributed evenly inside the femoral head and looked like a bird's net. Three months after operation, the blood vessel was still wider, but blood flowed faster and its termity changed roundish, and the bird's net changed greatly and capillaries reached the subchoronal zone of femoral head.Conclusion Blood flow was well reestablished after the treatment of ANFH by DSA. It can be easily checked with less damage, large liability, and clear picture.
