Free Flap Surgery
Microsurgical Transfer of Healthy Tissue to Reconstruct Complex and Extensive Defects
Free Flap Surgery is an advanced reconstructive procedure in which skin, fat, muscle, fascia, or a combination of tissues is transferred from one part of the body to another to reconstruct areas with significant tissue loss. The transferred tissue is completely detached from its original blood supply and microsurgically connected to blood vessels at the reconstruction site.
Free Flap Procedures
- Free Skin & Soft Tissue Flap – Transfer of healthy skin and underlying soft tissue to cover complex defects.
- Free Fasciocutaneous Flap – Transfer of skin and fascia for durable coverage of suitable wounds.
- Free Muscle Flap – Transfer of muscle tissue to fill deep defects and provide coverage over important structures.
- Free Musculocutaneous Flap – Transfer of muscle together with overlying skin for extensive tissue reconstruction.
- Free Osteocutaneous Flap – Transfer of bone along with skin and soft tissue for selected defects involving bone loss.
- Free Functional Muscle Transfer – Transfer of muscle tissue to restore selected functional movements in suitable patients.
- Microsurgical Vessel Repair – Precise connection of arteries and veins to establish blood flow to the transferred tissue.
- Complex Wound Coverage – Reconstruction of wounds with exposed bone, tendon, joint, nerve, or other vital structures.
- Post-Trauma Free Flap Reconstruction – Reconstruction of extensive tissue defects following severe accidents or crush injuries.
- Post-Cancer Free Flap Reconstruction – Reconstruction following removal of extensive cancerous or tumour-affected tissue.
Common Applications
- Severe traumatic injuries
- Crush injuries
- Extensive soft tissue loss
- Complex limb wounds
- Exposed bone or tendon
- Chronic non-healing wounds
- Post-cancer defects
- Head and neck reconstruction
- Breast reconstruction
- Complex hand and foot defects
- Limb salvage procedures
When Is Free Flap Surgery Considered?
Free flap surgery may be considered when a defect is too large or complex for direct closure, skin grafting, or simpler flap procedures, particularly when important structures such as bone, tendon, nerve, or joints are exposed.
The decision depends on:
- Size and depth of the defect
- Location of the reconstruction
- Type of tissue required
- Condition of surrounding tissues
- Availability of suitable blood vessels
- Presence or control of infection
- Functional requirements of the affected area
- Overall health and healing capacity of the patient
Vessel Repair
Advanced Microsurgical Repair to Restore Blood Flow and Preserve Injured Tissues
Vessel Repair is a specialised surgical procedure used to repair damaged arteries and veins following traumatic injuries, crush injuries, lacerations, or complex wounds. Restoring adequate blood flow is essential for maintaining tissue viability and, in selected cases, preserving an injured finger, hand, or limb.
Vessel Repair Procedures
- Arterial Repair – Microsurgical repair of damaged arteries to restore blood flow to the affected tissues.
- Venous Repair – Repair or reconstruction of injured veins to support proper blood drainage.
- Direct Vessel Repair – Precise repair of suitable vessel injuries when the damaged ends can be safely reconnected.
- Vessel Grafting – Use of a suitable graft to bridge a damaged or missing section of a blood vessel.
- Vascular Anastomosis – Microsurgical connection of blood vessels to re-establish circulation.
- Revascularisation – Restoration of blood flow to a severely injured but incompletely amputated finger, hand, or limb.
- Replantation Vessel Repair – Microsurgical repair of arteries and veins as part of replantation surgery.
- Hand & Finger Vessel Reconstruction – Repair of damaged digital and hand blood vessels following traumatic injuries.
- Limb Vessel Reconstruction – Reconstruction of selected arterial or venous injuries involving the upper or lower limb.
- Free Flap Vessel Repair – Microsurgical connection of donor and recipient blood vessels during free tissue transfer.
Common Causes
- Road traffic accidents
- Industrial and workplace injuries
- Machinery-related injuries
- Deep cuts and lacerations
- Crush injuries
- Sharp-object injuries
- Traumatic amputations
- Complex hand injuries
- Open fractures
- Severe soft tissue injuries
When Is Vessel Repair Considered?
Vessel repair may be required when an injury causes significant damage to an artery or vein, reduced blood flow, active bleeding, or threatened tissue viability.
The treatment approach depends on:
- Type and location of vessel injury
- Extent of vascular damage
- Degree of blood-flow compromise
- Condition of surrounding tissues
- Presence of contamination or infection
- Associated nerve, tendon, bone, or soft tissue injuries
- Time since injury
- Overall health and healing capacity of the patient
Replantation Surgery
Advanced Microsurgical Restoration of Amputated Fingers, Hands, and Selected Limbs
Replantation Surgery is an advanced microsurgical procedure performed to reattach a completely or partially amputated body part following a traumatic injury. The procedure involves carefully reconnecting bones, tendons, nerves, arteries, and veins to restore blood circulation and, where possible, preserve the function of the injured part.
Replantation Procedures
- Finger Replantation – Microsurgical reattachment of completely or partially amputated fingers in suitable cases.
- Thumb Replantation – Reconstruction of an amputated thumb with particular focus on preserving essential hand function.
- Hand Replantation – Microsurgical reattachment following traumatic amputation of the hand.
- Wrist & Forearm Replantation – Reconstruction of selected amputations involving the wrist or forearm.
- Partial Amputation Reconstruction – Treatment of injuries where part of the tissue remains attached but blood supply is severely compromised.
- Revascularisation – Restoration of blood flow to a severely injured but incompletely amputated finger, hand, or limb.
- Bone Fixation – Stabilisation of the amputated segment to restore structural continuity.
- Tendon Repair – Reconnection or repair of damaged tendons to support future movement.
- Nerve Repair – Microsurgical repair of injured nerves to support recovery of sensation and function.
- Blood Vessel Repair – Precise connection of arteries and veins to restore circulation.
- Soft Tissue Reconstruction – Restoration of damaged skin and soft tissues when required for successful replantation.
Common Causes
- Road traffic accidents
- Industrial and workplace accidents
- Machinery-related injuries
- Crush injuries
- Sharp-object injuries
- Traumatic amputations
- Severe hand injuries
- Agricultural machinery accidents
When Is Replantation Considered?
Replantation is not suitable for every amputation. The decision depends on several factors, including:
- Level and type of amputation
- Condition of the amputated part
- Degree of crush or tissue damage
- Time since the injury
- Condition of the blood vessels
- Level of contamination
- Patient’s overall health
- Functional importance of the amputated part
Replantation is an emergency procedure, and early specialist assessment is essential when an amputation occurs.
