Background:
We report our initial experience with LeGoo (Pluromed Inc, Woburn, Mass), a temporary thermoreversible occlusive gel, in peripheral vascular revascularization.
Methods:
Between 2007 and 2010, LeGoo was used to occlude target vessels during bypass surgery in 14 patients who required infrainguinal revascularization.
Results:
Proximal occlusion of the target vessel was obtained with a mean quantity of 0.25 mL of LeGoo. Distal occlusion of the vessel was obtained with a mean quantity of 0.28 mL. One injection of LeGoo was sufficient to prevent backbleeding in 11 of 14 patients. The mean occlusion time was 13.4 ± 3.3 minutes. An injection of saline through the graft or better directly into the arteries was used to dissolve the gel. For our first case, a Fogarty catheter was used to remove residual gel from the anterior tibial artery.
Conclusions:
LeGoo gel can be used to stop blood flow in small-bore arteries in the lower limbs to allow anastomoses to be performed.
