Kristen L. Billiar

PURPOSE: The purpose of this study was to compare inflammatory responses, tissue integration, and strength of the acellular dermal collagen matrices AlloDerm((R))* Regenerative Tissue Matrix, Permacol**Surgical Implant (Permacol), and CollaMend*** Implant in a rat model for ventral hernia repair.

METHODS: Rats were randomized into four groups and abdominal wall defects repaired with an inlay graft of AlloDerm, Permacol, or CollaMend. Rats were sacrificed at six time points and the defect area was removed and analyzed for tissue integration and physical strength.

RESULTS: Variable cell infiltration was seen for the three implant groups. At of the all time points examined, cellular …

Prefabrication Of A Secondary Tram Flap., Geoffrey G. Hallock Md

Department of Surgery

A secondary TRAM flap was prefabricated in a rat model using the rectus muscle. The right rectus muscle was elevated as an inferiorly pedicled muscle flap in one experimental group (n = 6) and as a superiorly pedicled muscle flap in a second group (n = 5) and then sandwiched between a silicone sheet and the abdominal skin. Two weeks later, the abdominal skin and attached rectus muscle were elevated over the silicone sheet as a secondary TRAM flap. The surviving skin paddle areas of these prefabricated TRAM flaps were compared with superiorly (n = 7) and inferiorly (n = …
