Microsurgical procedures are performed on parts of the body that are best visualized under a microscope. Examples of such structures are small blood vessels, nerves, and tubes. Microsurgery uses techniques that have been performed by surgeons since the early twentieth century, such as blood vessel repair and organ transplantation, but under conditions that make traditional vascular surgery difficult or impossible.
The first microvascular surgery, using a microscope to aid in the repair of blood vessels, was described by Jules Jacobson of the University of Vermont in 1960. The first successful replantation (reattachment of an amputated body part) was reported in 1964 by Harry Bunke. This replantation of a rabbit's ear was significant because blood vessels smaller than 0.04 in (0.1 cm)imilar in size to the blood vessels found in a human handere successfully attached. Two years later, the successful replantation of a toe to the hand of a monkey was made possible using microsurgical techniques. Soon thereafter, microsurgery began being used in a number of...
