Absolutely not! This is considered a complication. This complication is one of the reasons The Vein Guys™ use the Venefit™ procedure (formerly called the VNUS Closure™ procedure). This procedure uses radio frequency, not laser to shrink and collapse the diseased vein. The outcome of radio frequency ablation is more predictable than laser because the heat source is monitored by the generator, a certified registered vascular technician and the surgeon. The risk of complications is significantly reduced.
