AbstractIntroductionPersistent pain following breast surgery is common and may be challenging to treat. In patients refractory to conservative treatments, ultrasound‐guided fascial plane blocks of thoracic nerves can be a useful option.ResultsThis type of neuro blockade technique provides advantages in terms of safety and efficacy that are convenient for physicians managing refractory and complex cases of post‐breast surgery syndrome.ConclusionThis technical review aims to present an up‐to‐date summary of the most common ultrasound‐guided fascial plane blocks for chronic pain in post‐breast surgery patients, provide a detailed technical description of each intervention, and propose preferred injections based on the anatomical location of the pain.
