There are some possible side effects. They
include:
-
Stinging or
pain at the sites of injection, swelling of the ankles
or feet, or muscle cramps.
This usually occurs when hypertonic saline solution is
used. Hive-like reactions usually go away within 10 to
15 minutes after injection.
-
Red, raised areas
at the sites of injection. These are similar to hives and
the response should disappear within a day or so.
-
Brown lines or
spots on the skin at the sites of treated blood vessels.
Darkened areas may result when blood escapes from treated
veins and are probably formed from iron in the blood. These
dark areas occur more often in patients who have larger
veins treated or those patients that tan easily. In most
cases, they disappear within a year, but they may last
longer.
-
Development of groups
of fine red blood vessels near the sites of injection of larger
vessels. About one-third of patients develop groups of vessels
especially on the thighs. Most disappear by themselves, some
need additional injection treatments or laser therapy, a few may
last.
-
Small, painful ulcers
at treatment sites either immediately or within a few days of
injection. These occur when some of the solution escapes into
the surrounding skin or enters a small artery at the treatment
site and can be successfully treated, but it is necessary to
inform the dermatologist immediately.
-
Temporary bruises.
Bruises usually occur after laser treatments and are probably
related to the thinness of blood vessel walls. They usually
disappear in a few weeks. Occasionally, bruising is seen with
sclerotherapy.
-
Allergic reactions to
sclerosing solutions. Although such reactions are uncommon, they
can be treated. Inform your dermatologist immediately.
-
Inflammation of treated
blood vessels. This is very unusual but when it occurs, it is
treated with medications such as aspirin, compression, antibiotics,
or heat.
-
Lumps in injected
vessels. This is coagulated blood and is not dangerous. The
dermatologist may drain the blood from these areas a few weeks after
injection.
Burning with discoloration of the skin.
