Fats and cholesterol may build up in the artery and cause blockage and narrowing in individuals. Atherosclerosis or arteriosclerosis is the condition when the arteries get narrowed down due to plaque build up. This condition causes many other problems like heart attack, angina etc.
Sometimes the plaque is very hard due to deposition of calcium within the plaque and in such cases the technique of rotablation is used .Rotablation is a noninvasive method used to treat the condition called atherosclerosis. The procedure clears the block in the artery and opens it up. Usually, rotablation is done in individuals before they undergo for angioplasty or stenting. Issues like narrowing of the blood vessels of the brain, arms, leg and kidney etc., can be treated with rotablation procedure.
The procedure is done under local anesthesia. A catheter is inserted into the artery through an incision made in the groin of the patient. A fluoroscope is used to guide the catheter during the procedure. The surgeon then injects a dye into the catheter to find out the location of the blockage. An X-ray of the inner part of the arteries is taken with the help of the dye, during the procedure. The location and extent of the narrowing are found exactly with this first step of the procedure called an angiogram.
After that, another catheter is inserted into the site of the blockage with a diamond tipped burr at its top. The arterial plaque is grated by rotating the diamond burr of the catheter. The dust particles of the plaque are then washed out through the circulatory system. A stent may also be placed by the surgeon in certain cases. It prevents the further risks for blockages. To prevent the dust particles of the plaque from entering the blood vessels, the surgeon may also attach a special device. The procedure simple and minimally invasive. If the patient experiences another blockage within six months after the rotablation procedure, a coronary angioplasty of CABG may be necessary. Rotablation procedure seeks 1-2 days of hospital stay after the procedure.
