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 dysfunction in these cases remains to be determined.
Changes in arterial pressure were not recorded during the whole procedure. Services on Demand Journal.

Clin Neurol Neurosurg ; Harwood Academic Publishers, London, ; pp: Overall, the risk of intracranial complications related to the most commonly performed trigeminal lesioning procedures is low, and serious extratrigeminal adverse events were absent in centers operating over patients We describe the case of a patient who developed a fatal intratemporal and subdural hemorrhage following PCTG and discuss the possible causes of technical failure with the aim of preventing such a dreadful complication.
J Comp Assist Tomogr ;4: Her hypertension was well controlled with regularly taken antihypertensive medications.
The mechanism could also be puncture related, but in any case, needle misplacement beyond or out of intraparequimatoso foramen ovale initially during insertion is just another technical error which must be also avoided. Another foramen close to the ovale is the innominate foramen or canaliculus of Arnold.

Introduction Percutaneous compression of the trigeminal ganglion PCTG is an effective and safe surgical technique for trigeminal neuralgia which is thought to be almost free of major complications ,5,7, A year review of percutaneous balloon compression of the trigeminal ganglion.
On the first postoperative day, the patient presented with somnolence, slurred speech, incoordination and ataxia. Unable to process the form. This can encompass a number of entities that share the acute accumulation of blood in the parenchyma of the brain. When the needle pass the foramen ovale a too steep insertion trajectory may carry it too far upward into the subtemporal subarachnoid space or against the temporal lobe, and when it is too far posterior it may enter the brainstem However, the exam of the x-ray obtained during balloon inflation showed a cylindrical shape revealing its location out of the Meckel, cave.
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.
At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate. Complications of percutaneous surgery for pain.

Needle for use during percutaneous compression of gasserian ganglia for trigeminal neuralgia. The mechanism of blood pressure elevation during gasserian ganglion heating is unknown, but it has been related with pain felt by the unanesthetized hfmatoma during the procedure. Spaziante el al, 24 reported the occurrence of subarachnoid hemorrhage filling the basal and sylvian cisterns in a 62 year old man who underwent PCTG; normal pressure hydrocephalus developed as a consequence, and the patient eventually died following various complications; the surgical procedure was apparently correct as the needle did not penetrate beyond the foramen ovale and the inflated balloon did not move out of the Meckel,s cave; intraparehquimatoso addition, the functional result was excellent indicating an appropriate compression of the gasserian ganglion, and both inteaparenquimatoso coagulation studies and cerebral angiography excluded an alternative cause for SAH in this patient; since he did uematoma show arterial pressure rises during the procedure, the authors attributed subarachnoid hemorrhage to piercing of the dura at the intracranial entry point with subsequent hemorrhagic extension into the CSF spaces.
Four years before the last admission he underwent PCTG at our Unit with a good functional result; entry into the foramen ovale with a gauge needle-cannula was readly achieved under lateral intraaparenquimatoso control, a 4 French Fogarty catheter was placed into the Meckel,s cave and the balloon was inflated for one minute showing the typical pear shape.
Routine preoperative analyses, coagulation studies included, were normal.
McGraw Hill, New York,pp: Acute subdural hemato,a intratemporal hematoma as a complication of percutaneous compression of the gasserian ganglion for trigeminal neuralgia I.
On the other hand, a close observation and careful control of the arterial pressure changes during the operation is mandatory, as many patients develop sudden rises in blood pressure which may also result in intracerebral hemorrhage or ischemic cardiac complications Long term results in cases.
Carotid-cavernous fistula following percutaneous retrogasserian procedures. Acute lesions are usually related to trauma, occur usually in severely ill patients, with coma, headache, vomiting, ocular motor nerves palsies, other cranial nerves palsies and respiratory arrest. 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. Spontaneous bilateral chronic subdural hematoma of the posterior fossa.
The anatomy of the gasserian ganglion and the distribution of pain in relation to injections and operations for trigeminal neuralgia.
Chronic subdural hematomas of the posterior fossa often present with nonspecific symptoms. WB Saunders Co, Philadelphia, ; pp: Acta Neurochir Wien ; Postoperative transient diplopia occurring in patients showing a pear-shaped balloon during surgery and satisfactory functional result have been attributed intarparenquimatoso IV or Hematmoa nerve compression nitraparenquimatoso the tentorium o within the cavernous sinus 14,17, Though different types of intracranial bleeding have been reported in the largest series of patients undergoing radiofrequency RF lesioning of the gasserian ganglion 26,27to our knowledge this is the first report of focal intracranial hemorrhage complicating PCTG.
In another patient showing brisk bleeding at the puncture site the operation was continued and the trigeminal lesion made after bleeding stopped spontaneously; six hours later a massive SAH ensued in the posterior and middle fossa bilaterally.
