Ultrasound-guided thoracic paravertebral block using a transverse in-plane approach at the level of the inferior articular process: a retrospective review of complications

The incidence of complications after an ultrasound-guided (USG) thoracic paravertebral block (TPVB) (0.70%),[1][1] including inadvertent pleural puncture (0%–0.6%)[1–3][1] or pneumothorax (0%–0.26%),[1–3][1] is relative low. However, there is a paucity of data on the overall incidence of
