Microvascular Surgery

This is an important branch of reconstructive surgery which has recently been started in Pakistan.This is a highly specialized procedure in which large body defects from cancer , trauma or birth defects are reconstructed with the help of microscope.

Microvascular surgery: Surgery on very small blood vessels such as those only 3 to 5 millimeters in diameter. Microvascular surgery is done through an operating-room microscope using specialized instruments and tiny needles with ultrafine sutures. Microvascular surgery is used to reattach severed fingers, hands, arms, and another amputated parts to the body by reconnecting the small blood vessels and restoring the circulation before the tissue starts to die. Microvascular surgery also can be used in reconstructive surgery

Treatment

Microvascular reconstructive surgery involves the transfer of autogenous vascularized tissue to reconstruct extensive tissue defects. Areas commonly reconstructed include the jaws and mouth, the throat, and all areas of the face, scalp, and neck. Depending on the recipient defect site created from either trauma and/or head and neck cancer, a plethora of possible donor sites are available for transplantation. These include the following:

  1. radial forearm  flap
  2. fibula  flap
  3. latissimus dorsi flap
  4. anterolateral thigh flap
  5. subscapular  flaps:  including scapula, parascapular, latissismus serratus rib free flaps
  6. rectus flap
  7. iliac crest  flap
  8. jejunal  flap
