Abstract:
Objective To explore the cause, influencing factor and possible solving method of transient adverse reactions during the operation. Methods Sixteen healthy beagles were undergone virtual PLDD. The changes of vertebral discs and the surrounding tissues were observed by high resolution CT and MRI at different periods after the operation, and the same investigation procedure was carried out after the sacrifice of beagles. Results The beagles of the conventional vaporization group occasionally had limb tic and whining in the operations. Pieces of necrosis and edema could be found in the tissues of intervertebral foramen at the paracentetic side. The histological changes in the negative pressure suction group were less than those in the conventional group. Conclusion The reversible damages of the surrounding tissuses were observed in the conventional group and continuing negative pressure suction during the operations can prevent the damages to the surrounding tissues, all of the changes could be clearly displayed by CT and MRI scan.
