静脉供血皮瓣营养面积的研究

Experimental study on the area size of flap nourished by vein

用成年健康家兔作模型,对静脉供血皮瓣的营养面积进行了实验研究。以供血静脉外径与营养皮瓣面积的比值作为主要指标,并同时对皮瓣轴型静脉的入、出端压力和氧含量进行了测定。结果表明供血静脉外径与皮瓣营养面积有直接关系,平均1mm外径血管可供养成活19.8mm×18.8mm的皮瓣。为临床设计静脉血供养皮瓣面积提供了实验依据。

The area of flap nourished by vein was experimentally studied. The ratio of supplying vein and the size of area nourished was used as main indicator. The inlet and outlet pressures and oxygen content in the vein were deter- mined. The results showed that the outer diameter of supplying vein was closely related with the size of area nourished by the vein. Quantitatively, the vessel of 1 mm could nourish a flap area of about 19.8×18.8 mm^2. Our results provided a experimental basis for the clinical design of flap nourished by veins.
