Abstract
Endovenous laser ablation is a reliable treatment for varicose veins, but traditional infiltration with sharp needles often causes discomfort and increases the risk of tissue or nerve injury. Motivated by the need for a safer and more comfortable approach, we adapted a blunt multiside-hole infiltration cannula, originally designed for liposuction, to deliver tumescent anesthesia in endovenous laser ablation. Inserted under ultrasound guidance through the same access site, it distributes anesthetic evenly with fewer punctures. This simple and low-cost technique improves patient comfort, enhances safety, and streamlines the procedure, offering a practical and more comfortable refinement.
