Report received that a surgeon was performing an arteriovenous loop graft of the thigh.He completed the arterial anastomosis and tunneled the graft.He then cut the graft to prepare for the venous anastomosis and found that the graft had de-laminated.Specifically, the outer-layer had separated away from middle layer over the thickest portion of the graft.Once completed the surgeon closed the opening and was happy that the graft was satisfactorily placed.Later the surgeon returned to see the pt and it was noted that the drain had filled with a certain amount of fluid.During inspection the surgeon found the graft to be weeping.He drained the cavity and applied some packing and closed.Some 12 hrs later the fluid draining into the drain had settled.
