Microvascular free flap surgery

Microvascular Free Flap Surgery is a highly advanced reconstructive surgical procedure in which tissue (skin, muscle, fat, or bone) is transferred from one region of the body to another along with its blood vessels and those vessels are attached to new vessels at the recipient site through microsurgical methods under the high power microscope.

Purpose of Microvascular Free Flap Surgery

It is generally employed for sophisticated reconstruction, particularly when:

  • There is extensive loss of tissue (e.g., following cancer resection, trauma, or infection).
  • Functional and cosmetic restoration is required.
  • Local flaps are not possible or inadequate.

Free flap reconstruction

Free Flap Reconstruction is an advanced reconstructive surgery in which tissue is totally separated from its native site (donor site) and relocated to another site (recipient site), including the artery and vein that feeds it. These vessels are subsequently microsurgically reattached to vessels at the recipient site to resume blood circulation and keep the flap alive.

What Is Free Flap Reconstruction Used For?

Free flap reconstruction to reestablish:

  • Form, function, and appearance following:
  • Cancer surgery (such as oral, breast, skin, or bone cancers)
  • Trauma (such as severe limb or facial injuries)
  • Congenital anomalies
  • Chronic wounds or osteoradionecrosis

What is free flap surgery?

Free flap surgery is an intricate microsurgical reconstructive operation in which tissue (such as skin, fat, muscle, or bone) is totally taken from one region of the body (donor site) and moved to another area (recipient site) to reconstruct or fix damaged or missing tissue. The transplanted tissue comes with its own blood vessels, which are joined to new blood vessels at the recipient site through microsurgery (extremely small stitches under a microscope).

Most Important Features of Free Flap Surgery

  • "Free" means the tissue is completely detached from its original location.
  • Blood vessels of the flap are reattached meticulously to preserve tissue viability.
  • Requires high precision and microsurgical skill.
  • Employed when local tissue is not enough or ideal for reconstruction.

Microvascular reconstruction procedure

Planning and Imaging

  • CT or MRI scanning, and Doppler ultrasound or angiography aid in the selection of optimal donor tissue and recipient vessels.

Tissue Harvesting

  • A block of tissue along with its artery and vein is dissected and carefully excised from a donor location (e.g., thigh, abdomen, forearm, or leg).

Recipient Site Preparation

  • The reconstructive area is prepared by cleaning and mapping out surrounding healthy vessels.

Microsurgical Vascular Anastomosis

  • In an operating microscope with high power, the donor vein and artery are attached to the recipient site's vessels by ultra-fine sutures (hair thinner than the hair) to re-establish blood flow.

Flap Insetting and Closure

  • The grafted tissue is molded and sewn back into the desired form to rebuild the lost or destroyed area.
  • The donor site is closed or rebuilt if necessary.

Postoperative Monitoring

  • The flap is monitored regularly for evidence of proper blood flow, with the use of Doppler probes or clinical assessment of color, temperature, and capillary refill.

Types of free flap surgery

DIEP Flap (Deep Inferior Epigastric Perforator Flap)

  • Donor Site: Lower abdomen
  • Tissue: Skin and fat (no muscle)
  • Use: Breast reconstruction following mastectomy
  • Benefit: Spares abdominal muscles; natural appearance and feel

TRAM Flap (Transverse Rectus Abdominis Muscle Flap)

  • Donor Site: Lower abdomen
  • Tissue: Skin, fat, and muscle
  • Use: Breast reconstruction
  • Benefit: Good blood supply; increased volume
  • Drawback: Muscle is lost

Fibula Free Flap

  • Donor Site: Lower leg (fibula bone)
  • Tissue: Bone (occasionally with skin and muscle)
  • Use: Mandible (jawbone) reconstruction
  • Advantage: Thick bone for dental implants

Radial Forearm Free Flap

  • Donor Site: Forearm
  • Tissue: Skin, fat, fascia
  • Use: Oral cavity, tongue, pharynx reconstruction
  • Advantage: Thin, flexible tissue; simple shaping

Anterolateral Thigh (ALT) Flap

  • Donor Site: Outer thigh
  • Tissue: Skin and fat (occasionally muscle)
  • Use: Head, neck, limb, or pelvic reconstruction
  • Advantage: High volume of tissue; long vascular pedicle

Latissimus Dorsi Flap

  • Donor Site: Upper back
  • Tissue: Muscle (occasionally with skin)
  • Use: Breast, back, or shoulder reconstruction
  • Advantage: Robust, dependable muscle coverage

Scapular or Parascapular Flap

  • Donor Site: Area of the shoulder blade
  • Tissue: Skin, fat, occasionally bone
  • Application: Intricate 3D facial or extremity deformities
  • Benefit: Nice contour for face or jaw repair

Head and neck free flap reconstruction

Head and neck free flap reconstruction is a microsurgery technique employed to restore damaged portions of the face, mouth, throat, or jaw due to cancer surgery, trauma, infection, or birth defects. The technique consists of moving tissue (with its blood supply) from a donor site and reattaching it through microsurgery.

Why It's Done

This reconstruction is often required after:

  • Oral cavity cancer surgery (tongue, floor of mouth, cheek)
  • Throat or larynx cancer
  • Jawbone (mandible or maxilla) removal
  • Skull base tumors
  • Facial trauma or radiation injury

Microvascular flap complications

Microvascular flap surgery is safe in experienced hands in over 90–95% cases but, like any complex operation, poses certain risks. The complications may occur in the flap itself, the donor area, or the outcome of the surgery.

Flap thrombosis

  • Blood clot blocks artery or vein

Flap necrosis

  • Tissue death due to poor blood flow

Venous congestion

  • Blood enters flap but doesn’t drain

Arterial insufficiency

  • Insufficient blood flow into flap

Infection

  • Local or systemic infection at flap site

Breast reconstruction free flap

Free flap breast reconstruction is a technique that reconstructs the breast with a woman's own tissue (skin, fat, sometimes muscle) moved from another site on her body. This is more natural than implants and is particularly useful after breast cancer mastectomy.

What Is a Free Flap?

A free flap involves the removal of tissue completely from its original location, together with blood vessels, and then reattached to chest vessels by means of microsurgery.

How the Procedure Works?

  • Donor site preparation: Tissue is removed together with its artery and vein.
  • Recipient site (chest): Surgeon excises damaged/scarred tissue and prepares vessels (internally often internal mammary or thoracodorsal vessels).
  • Microsurgery: Small-sized blood vessels are joined up under a microscope.
  • Closure and shaping: Tissue is closed and shaped into a breast form.
