Percentage of graft viability versus injected volume in adipose autotransplants.

An adipose tissue graft's ability to obtain nutrition through plasmatic imbibition occurs approximately 1.5 mm from the vascularized edge. This and the observation that only 40% of this peripheral margin is viable led the authors to create spherical and cylindroid models to correlate the volume and the percentage of graft viability to the initial injected volume in adipose autotransplants. The authors concluded that the percentage of graft viability depends on the thickness and the geometrical shape and is inversely proportional to the graft diameter if grafts with a diameter greater than 3 mm are considered.

Study of the histologic alterations and viability of the adipose graft in humans.

The authors describe a series of sections of adipose autografts in humans, focusing on the histological viability and the alterations observed in a postgraft followup. Five female patients aged 29 to 43 years were subjected to seven grafting sessions prior to a classic abdominoplasty. The autologous adipose tissue was grafted in the infraumbilical region. The grafting intervals were 60, 30, 21, 15, 8, 5, and 2 days before the surgical procedure. The grafted tissue of all groups was surrounded by a collagen capsule. The viable tissue was observed in the peripheral zone approximately 1.5 +/- 0.5 mm from the edge of the graft. A loss of approximately 60% of the grafted tissue was still noticed in this viable zone.
