This paper reports that the adjacent vascular bundle was transferred into tubed flap in order to investigate the course of the angiogenesis of the vascular bundle by method of microangiography, pathology, transparent tissue specimens and microvascular casts, and effect on blood supply by measuring blood flow and skin temperature. The studies gave us the following results: New capillaries of vascular bundle occurred at 2nd day after operation, and gradually increased in number and then formed rich bush-like vessels on the surface of vascular bundle. The time of the earliest anastomosis between the vessels of the implanted vascular bundle and the recipient site was four day postoperation. The early anastomosed vessels were a few capillaries and some of them were changed into vein-like or artery-like structure. Improving the blood circulation in tubed flap begins on five day postoperation. The anastomosed vessels between the vascular bundle and tubed flap tend to stabilize at 10 day postoperation. The higher pressure in small arteries of the vascular bundle may be one of the main factors that vascular bundle possesses potential ability in angiogenesis and improves the blood circulation.
本文报道，将相邻血管束转移至管状皮瓣中，通过微血管造影、病理学、透明组织标本和微血管铸型等方法，研究血管束的血管生成过程，以及通过测量血流量和皮肤温度研究其对血供的影响。研究结果如下：血管束的新生毛细血管在术后第2天出现，数量逐渐增加，随后在血管束表面形成丰富的丛状血管。植入血管束的血管与受区最早吻合的时间是术后4天。早期吻合的血管为少量毛细血管，其中一些转变为静脉样或动脉样结构。管状皮瓣的血液循环改善始于术后5天。血管束与管状皮瓣之间的吻合血管在术后10天趋于稳定。血管束小动脉中较高的压力可能是血管束具有血管生成潜能并改善血液循环的主要因素之一。
