The paravertebral approach is the most common technique for local anaesthetic and neurolytic lumbar sympathetic blocks. However, guidelines on the site of needle insertion differ. As there have been several case reports on accidental trauma to the ureter and the kidney, this study was undertaken to evaluate the site of paravertebral needle insertion and the fluoroscopic landmarks for lumbar sympathetic blocks by computed tomographic puncture simulation. METHODS. CT scans of 73 patients at the… Expand

Ultrasound-Guided Lumbar Sympathetic Ganglion Blockade Using Shamrock Method: A Prospective Case Series
Ultrasound-guided lumbar sympathetic ganglion blockade can be reliably accomplished using the Shamrock method, and was successfully visualized in all patients with a median ultrasound visibility score of 15. Expand
Topography of the lumbar sympathetic trunk in normal lumbar spines and spines with spondylophytes.
Spondylophytes influenced the location of the lumbar sympathetic trunk and the distribution of the local anaesthetic and the medial margin of the psoas muscle was confirmed to be a consistent reference point at intervertebral disc level L2/3. Expand

The contribution of sympathetic mechanisms to postamputation phantom and residual limb pain: a pilot study.
The results of this study suggest that sympathetic mechanisms play a role in PLP and to a lesser extent, RLP, but that blocks confer long-term benefits in only a small percentage of patients. Expand
