Differences between Closure-FAST Radiofrequency Catheter and Laser Catheter

What is the difference between the Closure-FAST radiofrequency catheter and the laser catheter? The Closure-FAST radiofrequency catheter procedure is standardised and safe. A generator is connected to the catheter outside the patient’s body; this maintains exactly the right working temperature over a period of 20 seconds and regulates the transfer of energy. Every section of the vein being treated receives the same amount of energy at the same time. Because the catheter’s heating element is 7 cm long, the same… weiterlesen →

Doctor qualified to treat varicose veins

How can I tell if a doctor is qualified to treat varicose veins? In Germany, only operating vascular surgeons are trained in the treatment of catheter techniques during their specialist training. The vascular surgeons at Dermatologikum Hamburg are trained in the application of blood vessel catheters and have years’ experience in treating artery disorders and varicose veins using catheters. Clinics that perform many operations per year tend to achieve the best results. We carry out a minimum of 250-300 operations… weiterlesen →

Closure-FAST catheter or laser catheter?

What are the advantages of Closure-FAST catheter compared to the laser catheter? The Closure-FAST catheter operation is carried out according to a the same standard operating procedure across the world. This is not the case with the laser catheter. The operating temperature of the Closure-FAST catheter is 120°C, which is significantly lower than the 1,000°C at which the laser catheter operates. The Closure-FAST catheter leaves the vein intact, whereas laser systems damage the wall of the vein and can thereby… weiterlesen →

Complications after Closure-FAST?

What complications can Closure-FAST cause? The skin has to be pierced in order to insert the catheter into the vein. The wound can bleed or become infected, or a cutaneous nerve can be damaged. More serious complications, such as thromboses, are very rare: they occur in fewer than 1% of cases. An injection to prevent thromboses is administered to patients before they undergo this procedure. Patients with a back-flow disorder have a lower risk of suffering a thrombosis during the… weiterlesen →

Daily routine and exercise after Closure Fast

When will I be fully fit again? You can go about your daily business straight after treatment. There is no need to rest following treatment, nor to elevate the legs. We recommend resuming sporting activity and going back to work on the day after your operation. You should, however, refrain from weight-lifting for 14 days after the operation because the additional pressure can lead to stretching of the veins. Playing sport and doing exercise will not compromise the success of… weiterlesen →

Advantages of the procedure

What are the advantages of the procedure? This is a minimally invasive intervention without incisions or scarring. Bleeding and pain are rare because the catheter does not damage any blood vessels. On the day of the operation, or at the latest on the following day, patients can resume their daily business. Patients do not normally need to take time off work.… weiterlesen →

Does Closure Fast cause any post-operative discomfort?

Does Closure Fast cause any post-operative discomfort? What discomfort can a patient expect following the treatment? The catheter causes a wound in the leg, which heals and turns into a scar. The patient can feel this transformation. The symptoms of the treatment are a slight tension in the inner thigh, a noticeable swelling of any treated veins that are close to the surface of the skin, and a weakening of the feeling in the calf or inner thigh. Most patients… weiterlesen →

Varicose veins: who suffers from them?

Varicose veins: who suffers from them? Who is likely to be affected by varicose veins? When should I go to the doctors? Anybody with weak connective tissue can develop varicose veins, even young people. Women are three times more likely to suffer from the condition. The most common cause is weak valves in the veins. This results in the blood being pumped through the defective veins to the lower legs instead of to the heart. If untreated, this additional burden… weiterlesen →

How do we treat varicose veins?

How do we treat varicose veins? Following a thorough examination, patients diagnosed with venous back-flow disorders will be advised to undergo Closure-FAST™ catheter treatment. A catheter is inserted into the vein, which is closed from within using high-frequency radiowaves (heat). Over time, the body transforms the remaining sections of vein into connective tissue and after one year they disappear entirely. This method replaces the stripping operation, can be conducted under either local or full anaesthetic, and either as an out-patient… weiterlesen →
