Regional anesthesia and pain medicine
-
In situ knowledge about the anatomic structures and the path of a needle percutaneously placed into the paravertebral space is an area that continues to be investigated. We describe an endoscopic technique that permits imaging of the contents and boundaries of the thoracic paravertebral space in cadavers. ⋯ The images help show the relationship of structures that are encountered during a paravertebral block. This new technique may be helpful in examining the spread of local anesthetic using dye or imaging the location of continuous catheters without having to dissect the insertion area.
