Computed tomography-guided chemical renal sympathetic nerve modulation in the treatment of resistant hypertension: A case report

摘要

BACKGROUND Resistant hypertension(RH)has always been a difficult problem in clinical diagnosis and treatment.At present,there is no recognized safe and effective minimally invasive treatment.CASE SUMMARY An 80-year-old woman was admitted to hospital due to trigeminal neuralgia(TN).The patient had a history of RH for more than 10 years and her blood pressure(BP)was not well-controlled.Before the treatment for TN,we decided to perform chemical renal sympathetic denervation with ethanol in the Pain Department of our hospital.One year after the operation,she stopped taking antihypertensive drugs,and her BP was satisfactorily controlled within 4 years after surgery.CONCLUSION Computed tomography-guided chemical renal sympathetic modulation may be a feasible method for the treatment of RH.
