| 摘 要： | 通过对肝动脉灌注造影,测出了周围组织束缚下内径为0.1mm以上的狗各级肝动脉管径随内压力变化的几何尺寸,得出在生理范围内,可用方程D/D_0=A’+B’_p表示各级肝动脉管径与压力的关系,获取了各级肝动脉在周围组织束缚的弹性变形系数。并发现在一定的高压下,其肝动脉不仅管径显著增大,而且有严重的血管曲张。

| Abstract: | The mechanical properties of the hepatic artery that is more than 0.1mm in diameter are initially studied in the paper. The equation D/D0= A' + B'p shows the relationship between the internal pressure p and the dimensionless parameter D/Do in physiological normal range. And elastio deformation constant of the hepatic artery is obtained. Uhder centai high pressure, the hepatic artery is obviously deformed and appeared to be vessel cirsoid. |
