Varicose veins (VV) or varicoses are the most common manifestation of chronic venous disease (CVD). They occur in a large number of people, and their prevalence increases with the age of the population and changes in lifestyle habits. The transition to a sedentary lifestyle is one of the more significant risk factors in the development of VV. Considering the pathophysiology of the disease itself, it is important to emphasize that lifestyle modification plays a crucial role in controlling its symptoms. In addition, there are various medications and compression devices available that help alleviate the clinical presentation. However, completely curing VV is achieved only through surgical treatment methods. For many years, predominantly invasive procedures were applied, such as cross-sectomy or high ligation and/or stripping or vein ligation, as well as microphlebectomy. Although cross-sectomy and stripping are still considered the gold standard for treating VV, vascular surgeons are increasingly turning to minimally invasive treatment methods, such as endovenous laser ablation (EVLA), radiofrequency ablation (RFA), mechanochemical ablation (MOCA) of veins, and various forms of sclerotherapy. The advantage of these procedures, besides being more comfortable for patients during and causing fewer complications after the procedure, is the possibility of performing them within the scope of one-day surgery. As the term itself implies, patients admitted for one-day surgery are discharged within one day, usually within 6-8 hours. The preparation for the procedure, as well as the recovery after it, take place at the patient's home. Tumescent anesthesia is the term for a form of local anesthesia used in the treatment of VV as part of one-day surgery, but nowadays there is a growing trend towards the use of therapeutic methods that do not require its use (e.g., MOCA, sclerotherapy, etc.). The procedure itself also follows conservative methods of VV treatment (compression stockings) and ultrasound control since duplex doppler ultrasound is the cornerstone in the diagnosis of varicoses. Both globally and in Croatia, there is a strengthening of one-day surgery, not only in the treatment of varicoses, but also in the diagnosis and treatment of numerous other conditions. Therefore, the goal is to allocate the necessary resources for the development of space and equipment for one-day surgery, thus enabling patients to have a shorter and more comfortable stay in the hospital, a safer and less painful procedure, a faster postoperative recovery at home, as well as providing physicians with better working conditions and easier collaboration.
