目的应用放射学及解剖学方法研究腹壁浅层静脉系统的血管构造。方法取10个新鲜尸体腹壁标本(20侧),从腹壁浅静脉将X线显影剂灌注入皮瓣,在灌注过程中应用三维CT进行扫描,将所获得的数据在CT工作站上进行图像重建与分析。在CT扫描完毕后对标本静脉进行蓝色颜料灌注及解剖,并与放射学研究结果进行对比。结果⑴腹壁浅静脉起源于脐周,斜向外下走向大隐静脉或股静脉;⑵腹壁浅静脉走行层次位于Scarpa筋膜浅层,靠近皮肤,走行深度为0.27～0.41;⑶腹壁深浅静脉吻合主要集中在脐周区域,可见腹壁下静脉的直接穿支与腹壁浅静脉相吻合。结论⑴腹壁浅静脉是浅层腹壁的优势回流静脉;⑵了解浅层腹壁静脉系统对腹部皮瓣尤其是DIEP皮瓣的选择、修薄有指导意义。
Objective To study the vascular structure of the superficial veins of the abdominal wall using radiology and anatomy. Methods Ten fresh cadaver specimens of abdominal wall (20 sides) were obtained. The X - ray contrast medium was infused into the skin flap from the superficial veins of the abdominal wall and scanned by three - dimensional CT during perfusion. The obtained data were reconstructed on CT workstation analysis. Blue vein perfusion and dissection were performed on the veins after the CT scan and compared with the radiological findings. (2) The superficial veins of the superficial veins were located in the superficial layer of Scarpa fascia, close to the skin, and the walking depth was 0.27-0.41. (3) The superficial veins of deep veins Mainly concentrated in the umbilical area, we can see the direct abdominal perforating branch of the abdominal wall consistent with superficial veins. Conclusion ⑴ Superficial abdominal veins are the superior reflux veins of superficial abdominal wall. ⑵ Understanding the selection of shallow abdominal veins system for the flap of the abdomen, especially DIEP flap, thinning is instructive.
