Comparison of injectate spread following transverse vs. sagittal in-plane ultrasound-guided thoracic paravertebral block: a cadaveric study
Both TI and SI ultrasound-guided TPVB approaches reliably target PVS. A predominantly cephalad distribution was noted with two approaches. No significant differences were observed between two approaches regarding the number of PVS segments stained, intercostal spread area, and the percentage of sympathetic chain stained. This study adds knowledge to the spread pattern of TPVB.
