Microvascular free flaps effectively manage large intracranial dead space and infection after surgery or trauma. This vascularized tissue transfer aids healing and combats infection, offering a vital solution for complex cranial defects.

Area of Science:

  • Neurosurgery
  • Plastic Surgery
  • Infectious Disease

Background:

  • Large acquired intracranial defects pose challenges, particularly when complicated by infection or tumor recurrence.
  • Managing intracranial dead space after reoperation is critical for patient outcomes.
  • Microvascular free flaps present a promising solution for these complex cases.

Purpose of the Study:

  • To evaluate the efficacy of microvascular free-flap surgery in treating postoperative intracranial infections.
  • To assess the management of large intracranial defects and associated infections.

Main Methods:

  • A multi-institutional retrospective review of patients undergoing microvascular free-flap surgery for postoperative intracranial infections (1998-2006).
  • Analysis included patients with large intracranial defects due to tumor, seizure, or trauma.

A Pre-clinical Rat Model for the Study of Ischemia-reperfusion Injury in Reconstructive Microsurgery

Published on: November 8, 2019

  • Free flaps (latissimus dorsi, rectus abdominis, omentum) and cranioplasty (titanium, Medpor) were utilized.

    • Main Results:

    • Six patients with large intracranial defects and postoperative infections were identified.
    • All patients underwent debridement and free-flap reconstruction.
    • Successful management of dead space and infection was achieved in all cases.

    Conclusions:

    • Vascularized free tissue transfer is effective in filling intracranial voids and delivering therapeutic agents.
    • Early application of microvascular free flaps is beneficial when intracranial dead space and infection coexist.
    • This technique offers a solution for life-threatening complications arising from trauma or surgery.
