摘要
目的 :研究根治性颈淋巴清扫术对头颈部血流动力学的影响。方法 :选用 4只成年猕猴 ,模拟人类双侧颈淋巴清扫术 ,作颈部静脉处理 ,观察颈部各重要血管的血流量和压力变化。结果 :颈部静脉的阻断会引起颈部静脉血流动力学指标的明显改变 ,被阻断的颈静脉越多 ,对颈部静脉的血流动力学指标干扰就越大 ;但对颈动脉的相关指标影响甚微。结论 :在根治性颈淋巴清扫术中 ,应尽可能保存颅内静脉回流通道以减少对颈部血流动力学的干扰。其中保留颈外静脉的术式是减少这一干扰的简单而有效的方法。
Objective:To study alteration of neck hemodynamics after ligation of jugular veins during radical neck dissection.Methods: 4 rhesus monkeys were selected to simulate the human bilateral radical neck dissection. After operation, the jugular veins were ligated or lossen and the blood stream quantities and blood pressure of jugular veins and arteries were measured simultaneously.Results: The hemodynamic index would changed after jugular vein was ligated, the more the jugular veins were ligated,the greater effects the hemodynamics index of jugular veins were occurred, but there was little effect on arteries.Conclusion: The external jugular veins have the effect of compensating cerebral venous outflow after removing the internal jugular veins, and the external jugular veins should be conserved when bilateral or unilateral radical neck dissection was done.
