What is lumbar Paravertebral?

The lumbar paravertebral space (LPVS) is limited anterolaterally by the psoas major muscle; medially by the vertebral bodies, the intervertebral discs, and the intervertebral foramen with its contents; and posteriorly by the transverse process and the ligaments that are interposed between the adjoining transverse …

Where is the paravertebral region?

They’re known collectively as the paravertebral muscles. The highest of them are attached to the base of the skull, the lowest ones arise from the sacrum and iliac crest, some in between are attached to the backs of the ribs, and many are attached to the transverse and spinous processes of the vertebrae.

What is a thoracic paravertebral block?

The thoracic paravertebral block (TPVB) is a peripheral nerve block performed by injecting local anesthetic (LA) into the thoracic paravertebral space (TPVS). The TPVB targets spinal and sympathetic nerves, in order to produce an ipsilateral segmental somatic and sympathetic block.

How does a Paravertebral block work?

Paravertebral block is a technique where local anaesthetic is injected into the space adjacent to the vertebrae to block the spinal nerves as they emerge from the intervertebral foramen. Here the spinal nerves are devoid of covering fascia making them sensitive to the action of local anaesthetics.
