A 55 year old woman presents with a history of tortuous veins on both legs and a related ache towards the end of the day. She finds these veins unsightly and would like to know whether she can have them treated.

What you should cover

  • Varicose veins are very common: 40% of men and 32% of women aged 18-64 years have this condition.1

  • Common presenting complaints are “heavy legs”, swelling, restless legs, cramps, itching, and tingling,2 but these symptoms are often unrelated to the presence of varicose veins.2

  • Document risk factors such as increasing age, family history, obesity, and occupational history associated with prolonged standing.3 Varicose veins may first become apparent during pregnancy and the risk increases with parity.1 3

  • Ask about red flag symptoms such as weight loss and rectal bleeding where varicose veins may be due to a pelvic or abdominal mass.

  • Ask about previous treatment of varicose veins and outcome. Document a history of deep vein thrombosis or thrombophlebitis, where varicose veins could be acting as collaterals in the presence of deep vein obstruction.3 Document symptoms of arterial insufficiency in patients with ulcers, as this situation is a contraindication to compression.

What you should do

  • Document skin changes, including pigmentation and lipodermatosclerosis, and complications such as ulceration, thrombophlebitis, or haemorrhage, and refer patients with these features to a specialist.4 Clinical examination to determine the site of venous incompetence is unreliable. The gold standard for determining this site is duplex scanning, which should be done in secondary care.1 3

  • Reassure patients with uncomplicated varicose veins that no treatment is needed.1 4 Because most people will not develop complications, treatment is usually not provided on the NHS. Surgery does not prevent long term complications, particularly leg ulceration, in patients with no history of ulcers. Varicose veins rarely “burst” spontaneously but are at risk of bleeding from direct trauma. Bleeding will stop with firm pressure.

  • Emphasise to patients with venous ulcers that the mainstay of treatment for ulcers is compression bandaging. Varicose vein surgery will not improve healing, but will reduce the risk of recurrence.5

  • Conservative measures include weight loss, regular exercise, prevention of constipation, elevation of limbs, and support hosiery. Compression classes vary between each country. We recommend below knee European class 2 or British class 3 stockings depending on local availability. These stockings should be worn all day and must be fitted correctly.

  • Interventional options range from open surgery, such as high tie and stripping with avulsions, to less invasive procedures, such as radiofrequency ablation, endovenous laser therapy, and foam sclerotherapy. All these interventions are effective with similar recurrence rates (13-30% at five years) and are routinely performed as day cases. Treatment options will depend on local availability. Patients undergoing surgery will usually attend a pre-operative assessment clinic. On the day of surgery, the surgeon will outline the varicosities with a marker pen. Although varicose vein surgery is safe, patients need to be aware of the risks of scarring, pain, bruising, sensory symptoms, infection, deep vein thrombosis, and recurrence. Inform patients that surgery will not alter skin changes (such as thread veins) and may not improve symptoms such as aching.

  • Open surgery is usually done under general or regional anaesthetic, such as spinal anaesthesia. Patients can go home the same day, and they may be advised to wear bandages or compression stockings postoperatively. They are advised to walk, but time off work may be needed depending on occupation. Instructions on driving are similar to those for other operative procedures.

  • Radiofrequency ablation and laser therapy do not remove the vein, but seal it off by use of localised high thermal energy. They are usually done under ultrasound guidance. Similar postoperative instructions apply here, but these procedures can be done under local anaesthetic and usually result in quicker recovery.

  • Foam sclerotherapy can be done in the outpatient setting and several cycles of injection may be required.

  • There is no nationally agreed policy on NHS treatment of varicose veins and primary care trust policy for funding is variable. Some healthcare providers judge that uncomplicated varicose veins are of low priority and are treated in primary care, whereas others still fund surgical treatment. Surgery is funded if the varicose veins are associated with the complications mentioned above.

Checklist: what to include in referral letter to vascular surgeon

  • Background information—symptoms, duration, risk factors including occupation, thromboembolic disease, other relevant medical history

  • Any treatment received so far and outcome (for example, trial of support hosiery, previous surgery)

  • Details of any complications

  • Most recent examination findings, how findings have evolved over time

  • Patient’s concerns and expectations
