目的:进行拉索式血管分流装置治疗四肢血管离断并缺损伤的体内试验.方法:建立四肢血管离断并缺损伤动物模型,用拉索式血管分流装置和硅胶管连接缺损血管两端,检测通血及血栓发生情况,并与常规缝线结扎合并硅胶管连接方法进行比较.结果:拉索式血管分流装置固定的血管具有与传统缝线结扎合并硅胶管分流装置相同的通血效果,但操作时间短,和常规缝线结扎合并硅胶管连接方法相比有显著性统计学差异(P<0.05).结论:拉索式血管分流装置对离断并缺损的四肢血管可简单有效地恢复供血,可为后送至有条件的医院进行血管移植创造有利条件.
Objective To execute in vivo experiment on the treatment of vascular disconnection and defect of the extremities with interlocking vascular shunt device.Methods An animal model with vascular disconnection and defect of the extremities was established.The shunt device and silicone tube were used to connect the two ends of the disconnected vessel,and then canalization and thrombosis by the device were compared with them by sutures and silicon tube.Results The shunt device combined with silicon tube gained the same canalization as that by sutures and silicon tube, while had significantly shorter operation time (P<0.05).Conchusion The interlocking shunt device restores efficiently blood supply of vascular disconnection and defect of the extremities,and thus facilitates blood vessel grafting in rear hospitals.
