What is hand vein treatment? Why hand veins become prominent, and what can happen during treatment

Hand vein treatment is a procedure to make prominent veins on the back of the hand less noticeable. The typical method is sclerotherapy, in which a medication is injected into the blood vessel to close it[1]. A report of 41 people who underwent sclerotherapy for hand veins showed that the procedure required an average of 1.5 treatments, with no serious complications[1]. However, research specifically on the hand is still limited, and if the prominence is caused by loss of volume rather than enlarged vessels, a different treatment may be more appropriate[1][2].

Why do hand veins become more prominent?

With age, the fat on the back of the hand decreases and skin elasticity declines[2]. As a result, the underlying veins, tendons, and bone contours become more visibly pronounced[2].

In other words, the blood vessels themselves may not have enlarged. Treatment options differ depending on whether you choose to close the vessels to make them less noticeable or add volume to reduce the prominence.

What does sclerotherapy involve?

A fine needle is used to inject medication into the vein, which damages the inner lining of the blood vessel to close it[3]. In the report above, foam-based medication (such as polidocanol 0.5%) was primarily used[1].

Veins that close successfully gradually transform into hard, cord-like tissue over time[3]. As a result, the blood vessels become less visible through the skin.

How many treatments are typically needed? What is the expected timeline?

In the report above, hand treatments averaged 1.5 sessions, ranging from 1 to 5 sessions[1]. Some people complete the treatment in one session, while others require multiple treatments.

Note that this report was a retrospective review at a single facility, with 41 participants, most of whom were women, with an average age of 55.8 years[1]. It is not yet known whether the same results will apply to people of different ages or with different hand conditions.

What side effects can occur?

The relatively common side effect on the back of the hand was the formation of blood clots within the treated vein, which occurred in 15.2% of procedures[1]. Nodules, swelling, pigmentation changes (brown discoloration), and prolonged redness were rare[1].

A systematic review of sclerotherapy across all body areas indicates that pigmentation changes typically fade within 6–12 months, though in 1–2% of cases they may persist[4]. In some locations, nerve damage can occur, and cases have been reported in which nerve involvement near the hand was a concern[4].

Though rare, procedures involving blood vessels carry the potential risk of serious complications such as blood clots traveling to the lungs or elsewhere[3]. If you experience severe pain, swelling, numbness, or shortness of breath after treatment, contact your clinic immediately.

How do treatment options compare, and how do you choose?

If loss of volume is the primary cause of prominence, injection to restore volume is another option. In the United States, hyaluronic acid products have been approved for the purpose of restoring volume to the back of the hand[5].

In addition to sclerotherapy, vein treatment options include small surgical removal of the vein or closure from inside the vessel using laser or radiofrequency[6]. The choice depends on vessel diameter and location, and how much reduction in prominence you want.

What should be confirmed during consultation to determine if a treatment is right for you?

It is important to determine whether the prominence is caused by prominent veins, loss of volume, or both. The diameter of the veins and whether blood clots have formed in the past also affect treatment options.

Ask about the expected number of treatments, precautions after the procedure, and how side effects will be managed. Since the best approach cannot be determined from an article alone, have your hand examined in person before making a decision.
