|January 1, 1984
Summary
Pourfour Du Petit's syndrome, characterized by cervical sympathetic nerve irritation, is the opposite of Horner's syndrome. This case report details its occurrence following a brachial plexus block.
Area of Science:
- Neurology
- Autonomic Nervous System Studies
- Surgical Complications
Background:
- Horner's syndrome involves paralysis of the cervical sympathetic outflow.
- Pourfour Du Petit's syndrome results from irritation of the same nerves.
- Understanding sympathetic nervous system dysfunction is crucial in clinical practice.
Observation:
- A case of Pourfour Du Petit's syndrome was observed.
- The syndrome manifested after a brachial plexus block procedure.
Findings:
- The case illustrates the direct link between brachial plexus anesthesia and sympathetic nerve irritation.
- This presentation is considered the inverse phenomenon to Horner's syndrome.
Implications:
- Brachial plexus blocks require careful consideration of potential autonomic nervous system side effects.
- This case expands the understanding of iatrogenic sympathetic nervous system disorders.
- Awareness of Pourfour Du Petit's syndrome is important for clinicians managing patients post-nerve blocks.
