ABSTRACT

OBJECTIVE To observe the feasibility and safety of cryoablation of cervical lymph node metastases for nonsurgical candidates.METHODS The procedure was performed after achievement of local anesthesia for 15 cases.In this clinical study,local anesthesia with no sedation was performed to all the patients.In all cases,patients underwent two freeze/thaw cycles.RESULTS Tumors of 14 patients were thoroughly covered by ice balls.In one patient,96% of the tumorous lesion was covered by ice balls.In these patients,no complicated complication was observed during the treatment.CONCLUSION Percutaneous cryoablation therapy for cervical lymph node metastases under ultrasonic guidance is a feasible and minimally invasive method with satisfactory local control.
