The Vein Institute of South Mississippi is a specialized vein-care practice serving patients in Hattiesburg, D’Iberville, and Meridian. Founded and led by Dr. J. Keith Thompson, a board-certified vein specialist with more than 18 years of experience, the institute focuses on diagnosing and treating venous conditions affecting the legs. Its care addresses concerns including varicose veins, spider veins, venous ulcerations, leg swelling, and circulation issues.

The practice offers a range of in-office treatments, including vein ablation, sclerotherapy, microphlebectomy, and Varithena®. It also uses endovenous laser ablation, FDA-approved sclerosing solutions, and other minimally invasive approaches. The institute describes many procedures as requiring little to no downtime, helping patients return to their usual routines. Patients can explore treatment information, frequently asked questions, educational resources, and financing options, or use the venous insufficiency awareness quiz to learn more. With three South Mississippi locations, the Vein Institute provides consultations and specialized leg vein care, with a focus on current treatment technologies and less invasive solutions.
