Use of varioscope in free microvascular tissue transplants.

Since July 2002, the author has performed 12 consecutive free flaps using a new device, the Varioscope AF3, in order to evaluate its efficacy. The Varioscope is a world-patent novelty by Life Optics (Vienna, Austria) that combines the philosophy of microscopes and loupes. Specific advantages such as reduced cost, freedom of movement, portability, and a magnification range between 3.6-7,2x are some of the reasons that convinced the author to use the Varioscope initially. The overall success rate is similar to that obtained with a microscope or high-power loupes. The results show that the Varioscope AF3 could be safely employed in the majority of free-tissue transfers as sole means of magnification. However, for digital replantations or vessels with a diameter of less than 1 mm, a microscope might be necessary.
