Endovenous laser therapy (EVLT)—often referred to as endovenous laser ablation (EVLA)—has emerged as a highly effective, minimally invasive technique for the management of superficial venous insufficiency, most notably varicose veins of the lower extremities. By offering a safer alternative to traditional surgical stripping, EVLT quickly gained traction among vascular specialists due to its high success rates, favorable patient outcomes, and rapid recovery. Yet, despite its widespread adoption, potential complications and technical considerations must be well-understood to maximize the safety profile and achieve optimal early efficacy. This review provides an in-depth analysis of EVLT, focusing on mechanisms of action, early efficacy data, and complications that can arise in the early postoperative period. Emphasis is placed on recognizing risk factors, managing adverse events, and comparing EVLT with other contemporary therapies. Ultimately, the article underscores the importance of tailored patient selection, meticulous technique, and follow-up protocols to ensure both effectiveness and safety.
