Pourfour Du Petit syndrome after interscalene block

Abstract

Interscalene block is commonly associated with reversible ipsilateral phrenic nerve block, recurrent laryngeal nerve block, and cervical sympathetic plexus block, presenting as Horner's syndrome. We report a very rare Pourfour Du Petit syndrome which has a clinical presentation opposite to that of Horner's syndrome in a 24-year-old male who was given interscalene block for open reduction and internal fixation of fracture upper third shaft of left humerus.

Pourfour du Petit Syndrome After Supraclavicular Catheter Discontinuation

“…One case of PdPS occurred after a singleshot supraclavicular block done by paresthesia technique, 5 and the second case was associated with a single-shot interscalene block done using nerve stimulation. 6 Unlike these cases, our case is the first to be described after an ultrasound guidance technique and with a perineural catheter placement.…”

“…2 The condition has been associated with carcinomas, 2 intracranial processes, 3 central venous catheterization, nonpenetrating injuries of the cervical sympathetic chain and brachial plexus, 4 and brachial plexus regional anesthesia. 5,6 The course of PdPS is variable and may result in transient or permanent symptoms. Management includes supportive therapy for mild symptoms or a stellate ganglion block for more severe symptoms.…”

Neuro-Ophthalmology Annual Review

“…10 The 24-yearold man developed unilateral mydriasis, hemifacial perspiration, and eyelid retraction that resolved in concert with recovery from the anesthetic blockade. Interscalene block was used for repair of a humerus fracture and resulted in transient Pourfour Du Petit syndrome.…”

François Pourfour du Petit (1664–1741): pioneer in ocular biometry

“…There has also been a flurry of interest in the Pourfour du Petit syndrome, a rare disorder which is characterised by mydriasis, eyelid retraction and hyperhydrosis (excessive sweating), and is thought to be caused by irritative stimulation of the cervical chain. It is sometimes called ‘reverse Horner syndrome’ because of the pupil miosis which accompanies Horner's syndrome …”

“…It is sometimes called 'reverse Horner syndrome' because of the pupil miosis which accompanies Horner's syndrome. [19][20][21] Who was Petit, what were his achievements in ocular biometry, why are these so little remembered and are they still relevant? This review of his work attempts to provide answers.…”
