Compression regimes vary but it is generally accepted that compression after sclerotherapy reduces the incidence of side effects such as pigmentation and thrombophlebitis¹.
For large veins it is usual to apply local eccentric compression over the injection site using a foam rubber or cotton wool pad. The pad can be held in place using a limited stretch bandage. A medi class 1 or 2 compression stocking (18-21 or 23-32 mmHg at the ankle) is then worn over the top of the pad to provide general elastic compression. The pad and bandage should be kept in place for at least 3-7 days. The medi stocking should be worn for 2-3 weeks. For 1 week continuously and then during the day for a further 7-14 days.
After microsclerotherapy it is recommended that a Class 1 or 2 medi stocking (18-21 or 23-32 mmHg at the ankle) is worn for at least 4 days continuously and then during the day for a further 10 days.
Published data comes from Weiss et al (1999) who conducted a study on the effect of duration of compression following microsclerotherapy using USA classification Class 1 stockings (20-30 mmHg at the ankle). They concluded that wearing a stocking providing 20-30 mmHg compression at the ankle for 2-3 weeks significantly reduced the incidence of pigmentation and they advise patients to wear compression for 2-3 weeks.
Waterproof overstockings are available from STD Pharmaceutical to help the patient comply with the compression regime. The waterproof overstockings enable the patient to shower whilst their leg is bandaged.
