Sclerotherapy: everything you need to know about clearer, healthier-looking veins

KEIT Day Hospital has clinical facilities dedicated to medical treatments, organised to ensure appropriate standards of hygiene, procedural precision and patient comfort.
During sclerotherapy, the doctor identifies the veins to be treated and assesses their distribution, diameter and superficial characteristics, using appropriate instruments to administer the sclerosing solution. The procedure involves the use of fine, sterile, single-use needles selected according to the size and location of the affected vessels.
The organisation of the clinical facilities and the availability of medical resources allow the different stages of treatment to be managed, from skin preparation and disinfection to any necessary compression measures and observation immediately after the procedure.

KEIT Day Hospital works with medical professionals who assess and perform treatments, with particular attention to the specific expertise required for vascular procedures. In sclerotherapy, knowledge of venous anatomy and circulatory mechanisms is essential for identifying suitable vessels, selecting the injection technique and reducing the risk of complications.
Treatment is personalised according to the distribution of spider veins, vein diameter and the possible presence of underlying venous insufficiency. When indicated, the assessment may require further diagnostic investigations or consultation with a vascular specialist before proceeding.
An additional advantage is the presence of a multidisciplinary medical team within KEIT Day Hospital, allowing specialists in anaesthesia and intensive care or other medical disciplines to be involved when additional assessments or specific medical assistance are required.

Before sclerotherapy, the doctor carries out an individual assessment of the superficial veins, their distribution, any associated symptoms and the patient's expectations. The consultation includes taking a medical history, with particular attention to previous episodes of thrombosis, circulatory disorders, medications being taken, allergies, pregnancy, immobility and possible contraindications.
The clinical examination makes it possible to distinguish spider veins and small reticular veins from varicose veins associated with more significant venous insufficiency. When necessary, a venous Doppler ultrasound allows a more detailed assessment of circulation and helps identify any venous reflux that may require a different therapeutic approach.
The treatment plan is determined according to the type and extent of the veins, the formulation and concentration of the sclerosing agent and the approximate number of sessions. When sclerotherapy is not the most appropriate solution, the doctor assesses the available alternatives and discusses their limitations with the patient.

KEIT Day Hospital follows hygiene and infection prevention protocols that include disinfecting clinical areas, skin antisepsis and the use of sterile, single-use devices during injectable treatments. In sclerotherapy, particular attention is paid to skin preparation, needle handling and checking the packaging of the sclerosing solution.
The product is selected according to the clinical indication, vessel characteristics and planned administration method. Clinical documentation records the product's brand name, concentration, quantity used, batch number and treated areas, ensuring traceability of the preparation. These checks contribute to procedural safety and the proper handling of the materials and medications used.

Sclerotherapy is a minimally invasive procedure involving the injection of a sclerosing agent into selected blood vessels. It is generally performed without general anaesthesia but requires careful assessment of circulatory conditions and an appropriate administration technique.
In addition to temporary effects such as minor bruising, redness, tenderness and hardening of the treated veins, hyperpigmentation, the appearance of new superficial capillaries, venous inflammation or allergic reactions may occur. Less common but potentially serious complications include skin damage with ulceration, deep vein thrombosis and thromboembolic events. Some complications may occur even when the treatment is performed correctly.
Appropriate patient selection, adherence to recommended doses and administration methods, and prompt recognition of abnormal symptoms are essential for reducing risks and managing any complications.
One of KEIT Day Hospital's distinguishing features is the availability of hospital infrastructure and a multidisciplinary medical team. The facility has three equipped operating theatres, specialists in anaesthesia and intensive care, equipment for monitoring vital signs, emergency management devices and a postoperative recovery room. These resources provide additional medical support, alongside the specific protocols required to manage vascular complications and reactions to sclerosing agents.

At KEIT Day Hospital, patient care continues after sclerotherapy has been completed. Patients receive personalised instructions on physical activity, walking, the possible use of compression stockings, skin protection and warning signs requiring medical assessment.
Follow-up is determined according to the patient's individual response and the agreed treatment schedule. Follow-up appointments allow the doctor to assess the gradual resorption of treated veins, the appearance of any pigmentation changes and the presence of residual vessels. When indicated, the doctor may schedule additional sessions or further vascular investigations based on the results observed.
Patients are also informed of the need to seek immediate medical attention if they experience symptoms such as significant swelling in one leg, severe pain, difficulty breathing or chest pain.
For international patients, care may also continue remotely through communication with medical staff and guidance on necessary follow-up appointments. KEIT Day Hospital also provides an emergency contact number, available 24 hours a day, 7 days a week.

KEIT Day Hospital places particular emphasis on transparent information and treatment documentation. Before sclerotherapy, patients receive explanations about the characteristics of the veins to be treated, the selected sclerosing agent, the approximate number of sessions, expected benefits, the time required for the treated veins to be reabsorbed and potential risks.
Clinical documentation records the treated areas, the product used, its concentration and the quantity administered, as well as any reactions observed. When appropriate and with the patient's consent, photographic documentation is taken to compare the initial appearance with the results obtained during and after the course of treatment. The informed consent form, treatment quotation and administrative documentation also allow patients to understand the clinical and financial aspects of the treatment before undergoing the procedure.
