Overview

Microvascular surgery is a specialized surgical technique performed under a microscope to reconnect very small blood vessels and nerves, usually less than 3 mm in diameter. It is most commonly used in reconstructive surgery to transfer tissue (flap surgery), repair nerves, reattach amputated parts, and restore both form and function after trauma, cancer surgery, or birth defects.

What is microvascular surgery?

It is a technique where surgeons use a high-powered microscope and delicate instruments to repair or connect tiny blood vessels and nerves. This allows transplanted tissue (flaps) or reattached parts to receive proper blood supply and survive.

When is microvascular surgery needed?

It is often performed in cases such as:

  • Reconstructive surgery after cancer removal (head, neck, breast, limbs)
  • Trauma repair, including replantation of amputated fingers, hands, or limbs
  • Complex wound coverage where skin grafts are not enough
  • Peripheral nerve repair or grafting
  • Congenital defect correction in children
Is microvascular surgery safe?

Yes. Microvascular surgery has high success rates when performed in advanced centers. Risks include flap failure, infection, or clotting of small vessels, but with modern techniques and close monitoring, these are rare.

What are the benefits of microvascular surgery?
  • Restores both appearance and function after trauma or cancer surgery
  • Allows transfer of healthy tissue (skin, muscle, bone) from one body part to another
  • Saves limbs that might otherwise require amputation
  • Improves quality of life with long-term, durable reconstruction
How long is recovery after microvascular surgery?
  • Hospital stay: usually 7–10 days, depending on the surgery type
  • Initial healing: 2–4 weeks
  • Full recovery: 2–3 months, with physiotherapy if nerves or limbs are involved
  • Close follow-up is essential to monitor blood flow to the transplanted tissue
What is the difference between flap surgery and microvascular surgery?
  • Flap surgery involves moving tissue from one part of the body to another.
  • Microvascular surgery is the technique used to connect the tiny blood vessels and nerves of that flap to the new site.

Together, they form the basis of modern reconstructive surgery.
