A short YouTube video (spoken by Robert Whitfield MD) introducing microsurgery: definition, scale (sutures finer than hair; vessels ≈2 mm), and the concept of tissue "flaps" or composites (skin, fat, fascia, muscle, bone) used to reconstruct tissue and restore blood flow.
I really got interested in microsurgery. So microsurgery is taking basically suture finer than your hair and sewing together blood vessels that are about 2 millimeters in diameter. So think of like putting together coffee stirrers to re establish blood flow. And so you can take what's called a composite of tissue or a flap. Could be skin and fat. Connected to the blood vessels could be skin, fat, fascia, which is a thin layer of connective tissue. It can include muscle, it can include bone, it can just be skin and fashion bone. There's all sorts of ways to do it based on what you're trying to do.
