Microvascular surgery is performed on very small blood vessels, typically 3 to 5 millimeters in diameter, using an operating microscope, specialized surgical instruments, and tiny needles with ultrafine sutures.
Microvascular surgery is used to reattach severed fingers, hands, arms, and another amputated parts to the body. This is done by reconnecting the small blood vessels, thus restoring circulation before the injured tissue begins to die. Microvascular is also used in reconstructive surgery.
The transplanted healthy tissue from a distant site is called a "free flap". This healthy tissue is moved to the site of the wound where blood circulation is restored.
Injuries of the radial or ulnar arteries are common in distal forearm lacerations. Most of these injuries are associated with nerve and flexor tendon injuries. Although it has been noted that the final results of these injuries are mainly dependent on the associated injuries, loss of ulnar or radial perfusion to the hand can lead to cold sensitivity, muscle and bone atrophy, and loss of strength, for these cases microvascular repair of ulnar, radial or brachial artery can save limb of patient.
