  1. 1. THE USE OF URINARY BLADDER MATRIX (ACELL) IN THE TREATMENT OF COMPLICATED OPEN WOUNDS Alexis Lanteri Parcells, M.D Ian C. Hoppe, M.D. Brenon Abernathie, M.D. Ramazi O. Datiashvili, M.D. Ph.D University of Medicine and Dentistry of New Jersey Division of Plastic Surgery Department of Surgery Newark, NJ USA
  2. 2. Background • Annual wound care cost to the US healthcare system is more than $20 billion • Management of complicated open wounds is a challenge when reconstructive options are not applicable • Cellular and molecular research conducted by Badylak in 2002 demonstrated that scaffolds derived from urinary bladder matrix provide a biocompatible material that allows inductive tissue remodeling and wound closure
  3. 3. Urinary Bladder Matrix (UBM) • •Core Structure: bimodal surface • Epithelial basement membrane • Lamina propria • Growth factors •Healing Response • Autologous progenitor stem cells • Chemotactic and mitogenic activity • Antimicrobial activity • Site-specific tissue remodeling
  4. 4. Material & Methods • 5 Patients • Weekly dressing changes • Mean length of treatment: 20 weeks • Result of treatment: 100% wound healing
  5. 5. Case Presentation A 61-year-old woman sustained a severe crushing injury to her right knee. At an outside institution, the wound was debrided and patella removed. The patient developed a large open wound of the anterior knee with exposed knee joint. A gastrocnemius muscle transfer and TRAM were attempted and both failed. VAC therapy alone was attempted and was unsuccessful. The patient developed occlusion of her SFA and acute DVT, which precluded further reconstruction. The patient was told she may need an above-the-knee amputation. After consultation and evaluation at UMDNJ University Hospital, we managed the wound by application of Acell UBM in combination with VAC therapy at this initial stage
  6. 6. In 8 weeks Case Presentation
  7. 7. In 16 weeks VAC Therapy Discontinued Case Presentation
  8. 8. In 24 weeks The wound completely closed Case Presentation
  9. 9. Conclusions • Our experience shows urinary bladder matrix to be an effective method in management of complicated open wounds in selected cases • Further studies need to be implemented to confer this conclusion
