Edit Clarivein – the latest advance in treatment

<p><strong>How is Clarivein different?</strong></p> <p>The Clarivein device is inserted in the leg in the same way as the laser via a tiny nick in the skin around the knee. The catheter is passed up the saphenous vein to the groin under ultrasound control and positioned at the sapheno-femoral junction. The surgeon then presses the trigger on the device handle which starts the end of the catheter inside the vein rotating at approximately 3,500 rpm. The rotating wire scratches the inside of the vein and makes it go into spasm. The catheter is then slowly withdrawn back down the vein and the surgeon injects a drug called Fibrovein as the catheter is being withdrawn.</p> <p>The combination of the mechanical disruption and the chemical irritation causes the saphenous vein to block in much the same way as after a laser or VnUS closure procedure. As there is no heat generated during the procedure the surgeon doesn’t need to inject lots of local anaesthetic around the vein and the procedure is almost completely painless, as is the post-operative period. The latest follow-up data suggest that the outcomes at 2 years after Clarivein are as good as lasering and other techniques in terms of effectiveness at sealing the vein. </p>
