Transient Pourfour du Petit Syndrome

Pourfour du Petit syndrome caused by traumatic pseudo-aneurysm of the internal carotid artery

“…There are no epidemiological data about PDP syndrome, with information due only to cases reported since its description. PDP syndrome has been reported in association with carotid dissection [8], intracranial aneurysms [3], cervical contusion and brachial plexus injuries [9], post-traumatic syringomyelia, severe brain injury, aortic malformations and thyroid carcinoma [1]. In this present case, we believe that the sympathetic hyperstimulation occurred as a result of the cervical lesions caused by the projectile and its fragments.…”

“…This injury led to internal carotid artery dissection and pseudo aneurysm formation, which may have stretched the fibers of the cervical sympathetic chain causing ipsilateral stimulus to these fibers. PDP evolution is variable: the clinical characteristics can be maintained indefinitely or show remission of some of its signs in a few mo [1], or may also result in Horner syndrome [6,8]. In the presented case, PDP symptoms were gone at three weeks spontaneously, even before the endovascular treatment of arterial dissection.…”

Pourfour Du Petit syndrome after interscalene block

“…[14] Sympathetic dysfunctions are common following regional anesthetic procedures like subarachnoid, epidural, and brachial plexus blocks,[15] but in almost all cases, the dysfunction will be in the form of sympathetic block. The sympathetic excitatory symptoms are rare, often transient,[16] and under diagnosed. The pure excitatory sympathetic dysfunction like PDPs following brachial plexus block is a very rare presentation, and literature of Medline has only one reported case of PDPs following brachial plexus block.…”

“…Regional anesthetic procedures are also a common cause of sympathetic dysfunction, including PdPs [12, 13]. In these cases, symptoms are often transient [14] and may be underdiagnosed.…”
