兔股动脉和静脉预构轴型扩张皮瓣的实验观察

Objective To study the microcirculation and structural changes, surviving area of expanded prefabricated flaps. Methods A total of 40 New Zealand rabbits were divided randomly into expanded prefabricated, expender lined, simple prefabricated and free flap groups, each consisting of 10 rabbits. For the expanded prefabricated, expender lined and simple prefabricated groups, after the femoral artery and vein were transplanted into subcutaneous tissues of abdomen, and expanders were implanted into the deeper dartos. The free flap group was a blank control group. For the expanded prefabricated group, the expansion was carried out on 7th day postoperatively. On postoperative day 52, when the expander was fully expanded, island flaps with the prefabricated vessels as the pedicles were formed. The flaps were measured by laser Doppler flowmetry, light microscopy and digital re-cording of survival arca. Results When compared with the other groups, the perfusion volume of mi-crocirculation enhanced, flaps survival improved (97.54±2.73) %, blood capillary were stronger, to-gether with microscopic changes were significant in the expanded prefabricated groups (P<0.05). Conclusion Expandedprefabricated flaps can increase the survival size of the flaps and the safety of flap transplantation.

预构扩张皮瓣的实验研究

目的:研究预构扩张皮瓣的成活及其机制、微循环灌注量动态变化、超微结构改变。方法：选取成年雄性新西兰白兔36只,随机分为预构扩张组(A组)、扩张器衬垫预构组(B组)及预构组(C组),每组12只。股动静脉血管束移位后,前两组分别在肉膜深面植入50?ml扩张器,预构扩张组7?d后开始注水。定期对3组皮瓣进行微循环检测,并取样进行血管内皮细胞生长因子(VEGF)、碱性成纤维细胞生长因子(bFGF)及其受体、光镜及超微结构的检测与观察。第52天扩张完成后,形成仅以预构血管为蒂的岛状皮瓣,观察记录成活面积。结果：A组微循环灌注量明显高于B、C组（P＜0.05), 皮瓣成活面积占原始皮瓣面积的百分比大于B、C组（P＜0.05),VEGF、bFGF及其受体含量亦明显高于B、C组(P＜0.05),血管密度加大,超微结构改变显著。结论：预构扩张皮瓣能增大皮瓣成活面积,增加皮瓣移植的安全性。VEGF、bFGF及其受体含量的增加促进预构扩张皮瓣血管化进程。
