We and other authors have observed postoperative transient oculo-motor palsies when a balloon showing an “in vitro” like appearance is kept inflated more than the time necessary for checking its shape; however, the exact mechanism of oculomotor hemaatoma in these cases remains to be determined.
To our knowledge, this is the first report of a spontaneous chronic posterior fossa subdural hematoma related to an intraparenchymal cerebellar hemorrhage, without history of trauma, posterior fossa vascular pathology or anticoagulation.
Radiofrequency rhizotomy for trigeminal and other cranial neuralgias. We describe a case in a intraparenqujmatoso.
Keeping the needle within the foramen ovale all through PCTG makes very unlikely that the Fogarty catheter which has a soft, blunt tip, perforates the dura propia of the Meckel,s cave, or the lumen of the carotid artery. Occasionally we have observed another atypical balloon shapes such as oval, irregular or round which resulted in a good functional result as revealed by long-lasting pain control with the corresponding hemifacial hipoesthesia, despite that the nipple protruding through the poros trigemini and providing the typical pear-shape of a properly placed balloon was not observed.
J Neurosurg ; However, in some cases the tip of the needle is mislocated intracranially as evidenciated by either X-ray control, or the exit of CSF following stylet withdrawal.

Excluding the patient reponed here, and some complaining from postoperative transient headache and showing discrete meningeal sings suggestive of mild subsrachnoid hemorrhage, we have not had intracranial hemorrhagic complications in more than percutaneous retrogas-serian trigeminal procedures about two thirds RF lesions and one third PCTG.
Miranda Service of Neurosurgery. Reiwlta et al, 18 reported a patient who developed an arteriovenous fistula in the region of the territory of the external carotid artery with the fistulous connection arising at the origin of the middle meningeal artery from the pterygopalatine artery which was punctured because of the posterolateral direction of the needle emerging from the foramen ovale; the clinical course was benign with spontaneous closure of the fistula 19 days after puncture.
At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate. Spontaneous posterior fossa subdural hematoma as a complication of anticoagulation.
Subarachnoid hemorrhage and hemxtoma pressure hydrocephalus”. Summary The case of a 68 year-old man who developed a fatal intracranial hemorrhagic complication following percutaneous compression of the gasserian ganglion for trigeminal neuralgia is reported. The actual mechanism for intracranial bleeding resulting from percutaneous procedures on the trigeminal ganglion seems to be a direct vascular injury by a misplaced needle 26,27 or the inflated balloon.
Consequently, Sweet recommended interrupting RF rhizotomy when arterial bleeding is observed, even if its origin is the extracranial carotid artery, and resuming it some days later when the puncture site is healed 26, Postoperative CT scan performed five hours after surgery when the patient was comatose. On opening intraparenqiimatoso dura, the old, liquefied blood gushed out, suggesting hypertension in the posterior fossa.
Log in Sign up. Ann R Coll Surg Engl ; When analyzing extratrigeminal complications they found that 5 patients developed a carotid-cavernous fistula and 18 oculomotor palsies. This can encompass a number of entities that share the acute accumulation of blood in the parenchyma of the brain.
Case report and review of literature. Chronic hematomaa hematoma in the cerebellopontine angle. Dangerous rises in blood pressure upon heating of trigeminal rootlets; increased bleeding times in patients with trigeminal neuralgia.
A temporo-basal, medial and convexity subdural hematoma together with an intratemporal clot is shown.

To conclude, we have reported the first case of a fatal intracranial hemorrhagic complication of PCTG.
The mechanism could also be puncture related, but in any case, needle misplacement beyond or out of the foramen ovale initially during insertion is just another technical error which must be also avoided. In the patient reported here there were not changes in arterial pressure coincidental with balloon inflation, likely because it was out of the cave.
Carotid-cavernous fistula following percutaneous trigeminal ganglion approach. J Comp Assist Tomogr ;4: Only few patients treated with PCTG have been reported suffering extra or intracranial vascular or hemorrhagic complications. How to cite this article.
