- Complications of a properly performed and extravasated or intra-arterial injection of the sclerosing agent:
- Phlebitic irritation with local pain
- Risk of local necrosis (to be assessed as low) with parainjection of the sclerosing agent. The following procedure is recommended for accidental extravasation: fan-shaped injection of 5 ml isotonic saline solution to dilute the local concentration of the sclerosing agent.
- Local (injection-related) haematoma formation
- Allergic reactions; also iodine allergy when using sclerosing agents containing iodine
- Vasospasm
- Matting (occurrence of telangiectasia in the area of the sclerosed veins); migraine-like symptoms
- Flicker scotomas
- Thromboembolism
- Arterial injection with tissue necrotizing: in case of accidental intra-arterial injection (risk is extremely low with a practiced technique), 5000-10,000IE of heparin should be injected immediately through the remaining cannula. If this is not possible, 5000-10,000IE heparin is injected together with 250mg prednisolone i.v. To be able to perform an immediate thrombolysis attempt, an i.m. injection should be strictly avoided.
- generalized medicinal exanthema (rare)
- Late complications:
- Hyperpigmentations
- Nerve damage during extravasation
- Recurrences after sclerotherapy: the tendency to recur when using non-foamed sclerosing agents is high. It is between 40 and 70% over a period of 5 years. Control of the sclerosing result.
