Acıbadem International Hospital Cardiology Specialist Prof. Dr. Murat Sezer made a statement on the subject, stating that with the renal denervation method, which has become increasingly common in recent years, blood pressure that does not decrease despite regular multi-drug therapy can be controlled.
"Alternative method in resistant hypertension"
Acıbadem International states that hypertension, in other words blood pressure exceeding 140/90 mmHg, is treated with a single or multiple drug combination until the target blood pressure value (<120/80 mmHg) is reached, taking into account the patient's special condition and possible additional health problems. Hospital Cardiology Specialist Prof. Dr. Murat Sezer said, “Blood pressure control in most patients can be achieved by combining at least two molecules. However, in some patients, treatment goals cannot be achieved despite the 3-drug combination. Blood pressure that can be controlled with the combination of maximum doses of at least four different drugs is defined as 'resistant hypertension'. Research conducted; It reveals that approximately 13 percent of patients have resistant hypertension. The renal denervation method used in this table provides very successful results today. “Catheter renal denervation is also an important alternative treatment method for patients who are intolerant to multiple drug therapy or who have a medical disability to use one or more drug groups, as well as for patients who are drug incompatible.” he said.
"The sympathetic nerve network is being destroyed"
In the catheter-based renal denervation method; Prof. said that basically radiofrequency waves or ultrasound waves are used. Dr. Murat Sezer stated that with this method, which is performed by entering an artery in the groin, the sympathetic nerve networks surrounding the kidney vessels and causing blood pressure to rise are mechanically cut and continued as follows:
“Radiofrequency waves interrupt the nerve network around the kidney vessels with the heat energy created by moderate alternating current. In the system using ultrasound waves, the nerve network around the kidney vessels is destroyed by the energy released from ultrasonographic wave sources placed on a balloon catheter. In this way, the communication between the sympathetic nervous system and the renin hormone, which causes water and salt to be retained in the body and the vessels to contract, is interrupted and the mechanisms that increase blood pressure are taken under control.”
“It provides blood pressure control!”
Prof. Dr. Murat Sezer said, “Studies on the contributions of the renal denervation method to the control of blood pressure continue at full speed. According to the results of many studies; Very successful results are obtained from the renal denervation method in blood pressure control of a wide group of hypertensive patients (from patients with moderate hypertension to those with severe or resistant hypertension). Again in these studies; It was determined that the significant decrease in blood pressure was continuous and permanent.” he stated.
“There is no risk of serious side effects!”
The renal denervation process takes about an hour and is usually performed under deep sedation or general anesthesia. Prof. Dr. Murat Sezer stated that the possibility of serious side effects of the renal denervation method is almost non-existent and said, "Patients are discharged from the hospital 1 day after the procedure and can return to their daily lives." said.
