What is MOCA (Mechanochemical Ablation)?
MOCA, or Mechanochemical Ablation, is a modern, minimally invasive treatment for varicose veins and chronic venous insufficiency. It combines two techniques—mechanical disruption of the vein lining and the delivery of a medical sclerosant (a chemical agent)—to effectively close off diseased veins without the use of heat or large incisions. Because it doesn’t require tumescent anesthesia or thermal energy, MOCA typically results in less discomfort and bruising, making it a popular option for patients seeking a quicker recovery.
What to Expect During the Procedure
MOCA is performed in a clinic setting and usually takes less than one hour. After numbing a small entry point on the leg, a thin catheter is guided into the affected vein under ultrasound. The catheter then simultaneously delivers the sclerosant while rotating to mechanically disrupt the vein wall—allowing the vein to close effectively. Most patients experience little to no pain during the procedure and can return to their usual day-to-day activities immediately. However, it’s important to avoid strenuous leg exercises, heavy lifting, and swimming for at least two weeks post-treatment to support proper healing and ensure the best possible results.
