Compression stockings for post sclerotherapy?

There is alot of literature which supports using compression after sclerotherapy, which include improved results with regards discoloration (hyperpigmentation) and vessel closure (recanalization) as compared to non-compressive sclerotherapy. Generally, compression should be continuous for the first 72 hours, then be throughout waking hours and removed at bedtime for two weeks (minimum), depending on vessel size. the degree of compression can also vary with vessel size and other factors, but should be a minimum of 20- 30 mmHg

Following sclerotherapy I recommend compression for 48 hours.  If you have spider veins treatments at the thigh level then you should have both thigh and calf compression.  If you have only calf veins treated then compression is necessary only to the calf.  The reason for compression is to keep the solution in contact with the treated veins and to decrease the chances of staining, bruising and swelling. I recommend 24-30mmHg compression and I use Medivein. A good over the counter compression is GoldToe for calf length.
