In vivo experiment on treatment of vascular disconnection and defect of extremities with interlocking vascular shunt device / 医疗卫生装备

ABSTRACT

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.
