First successful renal denervation for intractable hypertension in the Honam region
Blood pressure was dropped in the patient in her 60s… CNUH Prof. Myeong-ho Jeong and his team

The team of Prof. Myeong-ho Jeong, Department of Cardiology, Chonnam National University Hospital recently performed a successful renal denervation using radio-frequency heat, an innovative treatment for intractable hypertension, for the first time in the Honam region.

Prof. Jeong and his team peformed an operation in June 29 on a 64-year-old female patient with intractable hypertension, who had blood pressure of 180/100mmHg even after the intake of more than 7 kinds of antihypertensive drugs. The blood pressure of the patient was dropped to 140/70mmHg after one day of operation and the patient was quickly recovered and then discharged.

This operation at Chonnam National University Hospital was the first in the Honam region after Seoul?Incheon?Gyeonggi?Busan region, and the third time among national university hospitals, after Seoul National University and Pusan National University.

Thus, Chonnam National University Hospital announced the good news of providing a safe and effective operation method to local residents who have suffered from intractable hypertension and was confirmed as the best regional hospital in the country responsible for health improvement of local residents.

Intractable hypertension is a condition in which normal blood pressure (systolic pressure 120mmHg/diastolic pressure 80mmHg) is not maintained even after taking 3 kinds of antihypertensive drugs or when more than 4 kinds of drugs are needed. About 5~10% of all patients with hypertension are known to have intractable hypertension.

Renal denervation is a therapy in which the renal nerve, one of the central sympathetic nerve system related to blood pressure regulation, that connects the kidney and the brain, is blocked by radio-frequency shock and the action of sympathetic nerve system that increases blood pressure is reduced. In renal denervation, complications and adverse side effects are greatly decreased, and the time required for surgery and recovery is reduced because it doesn't need general anesthesia. Most patients can return to their work and daily life immediately after surgery, but should consult with physicians for their judgment and recommendations first of all.

At present, this therapy has been approved in over 40 countries in the world including USA, Germany, Australia, and New Zealand, and performed on about 4,000 patients. In Korea, it was approved by KFDA last February and the clinical trials have been started in 10 major institutions since last April to test the operational effect and safety.
