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.

Synonyms or Alternate Spellings: Focal intracranial hemorrhages occurred in 19 patients. To quiz yourself on this article, log in to see multiple choice questions. Articles Cases Courses Quiz. 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, The finding of these lesions in patients without a history of trauma is even rarer, with only 15 cases reported, including those related to anticoagulant therapy 1, We also observed a low-flow carotid-cavernous fistula in a patient in whom the Meckel,s cave could not be entered which resolved spontaneously in 3 months 17 ; in this patient repeated needle insertions using different trajectories always resulted in brisk, pulsatile arterial bleeding, probably arising from the internal carotid artery.

The anatomy of the gasserian ganglion and the distribution of pain in relation to injections and operations for trigeminal neuralgia. However, the exam of the x-ray obtained during balloon inflation showed a cylindrical shape revealing its location out of the Meckel, cave. 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 fluoroscopic 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.

Posterior fossa subdural hematoma. Routine preoperative analyses, coagulation studies included, were normal. Discussion Our own experience and that of other authors suggest that PCTG is the simplest and less risky percutaneous technique for treating trigeminal neuralgia, provided that both an improper placement of the needle-cannula or inflation of the balloon out of the Meckle,s cave are avoided ,5,7,22, Only few patients treated with PCTG have been reported suffering extra or intracranial vascular or hemorrhagic complications.

CV Mosby, ; pp: Types of intracerebral hemorrhage include see related articles for full list: When reviewing the literature on the three percutaneous lesioning procedures of the gasserian ganglion relevant data emerge which must be considered for diminishing or preventing the risk of vascular or hemorrhagic intracranial complications.

WB Saunders Co, Philadelphia, ; pp: Postoperative transient diplopia occurring in patients showing a pear-shaped balloon hematpma surgery and satisfactory functional result have been attributed to IV or VI nerve compression against the tentorium o within the cavernous sinus 14,17, There was a marked midline shift.

This policy was not followed in the patient reported here in whom the foramen ovale limit was likely trespassed with the needle leading to catheter mislocation and balloon inflation out of the cave.

Hospital 12 de Octubre. We have also observed marked rises in arterial blood pressure during compression of the gasserian ganglion even under general anesthesia, which may be easily controlled with nitroprusside or better prevented by injecting lidocaine inrraparenquimatoso the Meckel,s cave before inflating the balloon 4,16, The complication was likely related to improper placement of the Fogarty catheter into the temporal fossa out of the Mecke1,s cave.

Percutaneous compression of the trigeminal ganglion for trigeminal neuralgia. Sweel 25has emphasized that intracranial hemorrhages occurring in patients exposed to percutaneous trigeminal lesioning procedures are not always puncture-related, but can be attributed to an anticoagulant or bleeding tendency, or to abrupt arterial blood pressure rises occurring during surgery.

Fifteen hsmatoma later, she presented to our outpatient clinic with complaints of continuous headache, somnolence and urinary incontinence. On opening the dura, the old, liquefied blood gushed out, suggesting hypertension in the posterior fossa.

Hematoma subdural

Anatomy of the cavernous sinus. In one case an infratemporal subdural hematoma occurred because of a needle puncture of the inferior temporal vein, the intraparenqujmatoso was removed and the patient recovered.

On the first postoperative day, the patient presented with somnolence, slurred speech, incoordination and ataxia. 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 Provided that the needle is appropriately positioned into the foramen ovale, venous bleeding may originate from the venous plexus crossing the foramen margins, and arterial bleeding may arise either from the meningeal accessory artery traversing the foramen, or from other local branches of the meningeal arteries 12, Trochlear nerve palsy after repeated percutaneous balloon compression for recurrent trigeminal neuralgia: Balloon compression rhizotomy in surgical management of trigeminal neuralgia.

A MRI Figs 2 and 3 showed a right posterior fossa extra-axial hematoma, hyperintense both on T1 and T2 sequences, compressing the right cerebellar hemisphere, and a hfmatoma, contiguous, intraparenchymal right cerebellar hematoma in subacute fase, with some edema; MRI angiography was normal.

McGraw Hill, New York,pp: In the patient reported here there were not changes in arterial pressure coincidental with balloon inflation, likely because it was out of the cave. Case intrapagenquimatoso This 68 year-old normotensive man had been suffering from typical trigeminal neuralgia located at the second and third trigeminal divisions on the left side for 6 years.

In fact, when reviewing the literature extratrigeminal complications following PCTG seem less hematoka than with other percutaneous techniques in which the peedle has to entry the trigeminal cistern ,5,9,11,22, We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma.

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. However, even if the needle seems to be correctly placed, it is not impossible for the catheter reaching the temporal fossa out of the cave as we have observed a cylindrical or “in vitro” like appearance of the balloon in patients who had the needle,s tip at or immediately below the limit of the foramen ovale suggesting that ihtraparenquimatoso piercing had occurred during needle,s insertion allowing the catheter to slip out of the cave.

Introduction Percutaneous compression of the trigeminal ganglion PCTG intraarenquimatoso an effective and intrapwrenquimatoso surgical technique for trigeminal neuralgia which is thought to be almost free of major complications ,5,7, J Neurosurg ; Percutaneous trigeminal nerve compression.

Another CT scan was performed and showed hydrocephalus, and a ventriculoperitoneal shunt was inserted Fig 1. Carotid-cavernous fistula following percutaneous retrogasserian procedures.

We indirectly assumed that the balloon was inside the Meckel,s cave in these instances, but we have not an explanation for these atypical shapes
