Renal Denervation Procedure – Plausible End to Chronic Hypertension Pill Therapy

Several hypertension patients are faced with lifelong intake of medicines for reducing their chances of suffering from heart attacks or stroke. Despite the lengthy daily pill intake, nearly half of these patients continue to have inadequately controlled blood pressure.

Hypertension or high blood pressure develops due to transmission of flawed signals from the brain to the renal nerves. These nerves present in the arteries deliver to the kidneys and play vital role in regulating blood pressure, though it is not completely clear the manner in which they do it.

In nearly ninety-five percent of the situations, there is no lone, specific cause for such flawed signals; however risk factors inclusive of age, binge drinking, inadequate dietetic intake, dearth of physical exercise and being obese are some of the identified aspects.

A normal blood pressure reading is about 120 by 80 and any reading that is 140 by 90 and above is a high reading indicating hypertension. Those suffering from this condition could endure acute headaches.

However, a number of individuals are asymptomatic despite having high blood pressure levels; hence it is a prudent practise to get blood pressure levels evaluated on a regular basis. Treatment of hypertension is also imperative as it is the key risk factor leading to cardiovascular ailments – the heart having to put in greater effort in pumping blood that tends to weaken it. The rising pressure has a damaging effect on the arterial walls that could cause blockages or even brain haemorrhage that are both causal in case of strokes.

Treatment generally initiates with lifestyle alterations like restricting alcohol intake and exercising. In case this does seem to have any effect, then lifelong medications are prescribed that have associated side-effects. These include feeling nauseous, giddiness, lethargy, blurry eyesight, nose bleeding, erratic heart beats or feeling breathless and skin rashes.

Till recent times, all showed to improvement with medicines or those unable to bear the drug side effects were left with no choices but to be hopeful that their situation would not deteriorate. However, renal denervation holds thrilling prospects and a highly commendable development in this field in the past five decades.

During the procedure a fine pliable tube (catheter) is fed via an artery in the groin area in the renal arteries. A line is then passed into the artery and with the assistance of a small electric current the renal nerves situated in the artery wall are ablated. This puts a stop to the flawed signals arising from the brain that tell the nerves to maintain high blood pressure.

The highlight of this procedure is that there is no form of harm done to the renal artery or the kidneys. Though the two renal arteries need this form of treatment, however the surgery merely involves a simple slit on the right side of the groin region with merely a small post-operative mark on the patient’s skin.

Generally, doctors administer 4-6 rounds of electric currents in 120 seconds burst intervals for treating the entire artery.

This procedure appears quite effectual. Though there could be re-growth of the nerves, there is no proof of whether they would re-acquire functionality. There is hardly any risk of blood loss or harm and is risk-free.

Though subsequent to the operation there would not essentially be a complete stoppage of blood pressure drugs though lesser tablets would be needed henceforth and the risk of suffering from heart attack or strokes would be considerably lowered as hypertension is under greater control.
