My surgeon has as optional equipment hand-out: this equipment: VascuTherm Iceless Cold Compression Unit. (expensive rental - minimum- 2 weeks/325 + tax cash only here in California) Unfortunately the system states I cannot post the intended video links so I suggest a search on Vimeo (nice simple video) or a much lengthier video on YouTube.
The positive side of this equipment is that you don't need to deal with ice. (We happen not to have an icemaker connected to our fridge and don't care to be running to the store to buy it and then have to store it.) The other positive side is that it includes a compression program.
