This produces unilateral (ipsilateral), segmental, somatic, and sympathetic nerve blockade in multiple contiguous thoracic dermatomes,1,2 which is effective for managing acute and chronic pain of unilateral origin from the thorax and abdomen.2 TPVB can also be used for surgical anesthesia in patients undergoing inguinal herniorrhaphy3 and breast surgery4–6 with improved postoperative outcomes.2,5 TPVB is traditionally performed using surface anatomical landmarks.2 Recently there has been an increase in interest in the use of ultrasound for peripheral nerve blocks,7–9 including TPVB.10–18 However, published data on ultrasound-guided (USG) TPVB are limited.10–20 This chapter describes the sonoanatomy relevant for USG TPVB.
