RFA VARICOSE VEINS

Author (rajnish). Submitted on Mon, 23 Jan 2012

Radio frequency ablation (RFA) is a medical procedure where part of the electrical conduction system of the heart; tumor or other dysfunctional tissue is ablated using the heat generated from the high frequency alternating current to treat a medical disorder. An important advantage of RF current (over previously used low frequency AC or pulses of DC) is that it does not directly stimulate nerves or heart muscle and can therefore often be used without the need for general anesthetic. RFA has become increasingly accepted in the last 15 years wish promising results.

An interventional pain specialist (such as an anesthesiologist), interventional radiologist or a cardiac electrophysiologist, a subspecialty of cardiologists, performs RFA procedures under image guidance (such as X-ray screening, CT scan or ultrasound).

RFA is performed to treat tumors in lung liver, kidney, bone and (rarely) in other body organs. Once the diagnosis of tumor is confirm, a needle-like RFA probe is placed inside the tumor.

The radiofrequency waves passing through the probe increase the temperature within tumor tissue that results in destruction of the tumor. Generally, RFA is used to treat patients with small tumors that started within the organ (primary tumors) or that spread to the organ (metastasis).

The suitability of a patient to receive RFA is decided by doctors based on multiple factors. RFA can usually be administered as an out patient procedure that may at times require a brief hospital stay. RFA may be combined with locally delivered chemotherapy to treat hepatocellular carcinoma (primary liver cancer).

The low-level heat (hyperthermia) created by the RFA probe causes heat-sensitive liposome to release concentrated levels of chemotherapy in the margins around the ablated tissue, which is a method commonly used to treat Hepatocellular carcinoma (HCC).

VARICOSE VEIN- NONINVASIVE TREATMENT

Normally, valves in your veins keep your blood flowing forward so it does not collect in one place. But the valves in varicose veins may be damaged, deformed, or missing. As a result, the veins stay filled with blood, especially when you are standing.

When you stand up, you can see varicose veins as large, bluish vessels that may feel like a "rope."

Non-surgical treatments for varicose veins can be performed in a doctor's office or clinic. You will receive local anesthesia to numb your leg. You will be awake but will not feel pain.

Sclerotherapy is one common treatment for varicose veins. Your doctor will inject salt water (saline) or a chemical solution into the varicose vein. The vein will harden and then disappear. Sclerotherapy works best for small spider veins.

Newer methods are also being use to treat varicose veins. One is called radiofrequency ablation. Another is called endovenous laser ablation. Each of these methods uses intense heat to treat the vein. During these procedures:

· Your doctor will puncture the varicose vein. Ultrasound (a painless way to see inside your leg) will guide your doctor during the treatment.

· Your doctor will thread a flexible tube (catheter) through the vein up to your groin. The doctor will inject a special solution into your vein to numb it.

· Intense heat will reach the vein through the catheter in the vein. The heat will close off and destroy the vein. The vein will disappear over time.

These newer procedures can treat varicose veins in the upper thigh only.
