This is called a V-A shunt (Ventricular-Atrial shunt). There are pictures of the two types of shunts in the pictures above. The shunt has a valve, which controls the amount of fluid that flows from the brain to the abdomen or heart. The most common complications of a ventricular shunt are infection and malfunction. Malfunction can be caused by blockage in the shunt, the shunt breaking or because a valve in the shunt is not working.
The minimum interval is 7 to 10 days for a course of treatments. Where you are correcting open pores, wrinkles, lines etc the interval can be quite close. The interval can be adjusted on your skincare therapists advice depending upon skin type and depth of treatment. Maintenance treatments on a 4 to 6 week basis are recommended. Skin renews itself approximately monthly and can take this amount of time to begin to see the true results of your microdermabrasion treatments.
*Do not get microdermabrasion if you have extremely sensitive skin, diabetes, vascular conditions like rosacea, skin inflammation, bacterial infections, lack of tactile sensation, keloid scarring, cuts and abrasions, or have gotten Botox within 72 hours.
