Figure 2: (a) US guided thoracic paravertebral block (TPVB). Trapezius muscle (TPZ)—Trapezius and ESM-brown outline; CTJ—pink; LA—dark blue; TP and rib-light blue, (b)case 1: US-guided paravertebral catheter. Epidural spread from TPVS—dark blue; Epidural catheter in TPVS—white arrows. (c)case 1: Contrast spread after thoracic paravertebral block. Epidural (anterior and posterior spread) from TPVS—light blue arrows; contrast spread along with the pre/para/intercostal spread—green arrows. (d)case 2: lateralization of epidural after ThPVB. Epidural (lateral spread) from TPVS; CTJ—green arrows; thoracic intervertebral foramina—yellow arrows, neuraxial space—yellow arrow
