An ultrasound-guided thoracic paravertebral nerve block was administered for left-sided abdominal pain. Lidocaine 0.4% (9.5 mL) was injected. Spinal anesthesia developed after the injection that resolved after 3 hours. One week later, a magnetic resonance imaging scan of thoracic spine identified a left T10 nerve root sheath cyst. It was postulated that the local anesthetic was injected into the cyst, which communicated with the subarachnoid space. This case report demonstrates the anatomic variations of nerve root sheath cyst sites and the risk of injection into intranerve root sheath cysts during interventional procedures.

Ultrasound-guided spinal anesthesia is an attracting and advanced technique. We developed a new paramedian transverse approach for real-time ultrasound-guided spinal anesthesia. Using this approach, t...
Adequate pain control after cardiac surgery is essential. Paravertebral block is a simple technique and avoids the potential complications of epidural catheters. The objective of this study is to c...
This study was undertaken to compare the analgesic efficacy of ultrasound-guided single-shot caudal block with ultrasound-guided single-shot paravertebral block in children undergoing renal surgeries.
Comparison of the Clinical Efficacy of 2 Paravertebral Block Strategies in Thoracic Surgery by Thoracotomy: by the Anesthetist (Paravertebral Block Guided by Ultrasound) and by the Thoracic Surgeon (Paravertebral Block Visual)
Post-thoracotomy pain is one of the most severe. The local analgesia allows its effective control and a reduction of postoperative morbidity and mortality. The gold standard for local ana...
The investigators hypothesize that the analgesic efficacy of ultrasound-guided serratus anterior plane block will provide better analgesia with fewer complications in comparison to ultraso...
Spinal anesthesia can be challenging in patients with lumbar scoliosis or previous lumbar spine surgery. This study aims to evaluate whether the use of the ultrasound-assisted spinal anest...
The study aims to investigate the pharmacokinetic of ropivacaine in patients undergoing ultrasound guided thoracic paravertebral block (TPVB) both after a single-bolus injection via the th...
The aim of this study is to compare conventional and ultrasound guided paravertebral blocks to with respect to efficacy, patient satisfaction and complication rates.
Nerve fibers which project from the central nervous system to autonomic ganglia. In the sympathetic division most preganglionic fibers originate with neurons in the intermediolateral column of the spinal cord, exit via ventral roots from upper thoracic through lower lumbar segments, and project to the paravertebral ganglia; there they either terminate in synapses or continue through the splanchnic nerves to the prevertebral ganglia. In the parasympathetic division the fibers originate in neurons of the brain stem and sacral spinal cord. In both divisions the principal transmitter is acetylcholine but peptide cotransmitters may also be released.
The collecting of fetal blood samples via ultrasound-guided needle aspiration of the blood in the umbilical vein.
A paravertebral sympathetic ganglion formed by the fusion of the inferior cervical and first thoracic ganglia.
Procedure in which an anesthetic is injected directly into the spinal cord.
The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses. The lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia.
Anesthesia is the loss of feeling or sensation in all or part of the body. It may result from damage to nerves or can be induced by an anesthetist (a medical professional) using anesthetics such as thiopental or propofol or sevoflurane during a surgical ...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
