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, Acute subdural and intratemporal hematoma as hmeatoma complication of percutaneous compression of the gasserian ganglion for trigeminal neuralgia I.

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.

Another CT scan was performed and showed hydrocephalus, and a ventriculoperitoneal shunt was inserted Fig 1. You can also scroll jntraparenquimatoso stacks with your mouse wheel or the keyboard arrow keys.

Hospital 12 de Octubre. It should noted in this respect that when the needle tip is at the porus trigemnni; it is 5 to 11 mm behind the profile of the clivus as seen in the lateral fluoroscopic control 26and that the exit of CSF does not necessarily means that the needle,s tip is into the cistern of the Meckels,s cave as it may flow from the subtemporal subarachnoid space.

Unable to process the form.

Correlación clínico-tomográfica del hematoma intraparenquimatoso

There is uncal herniation and hemato,a midline shift. The reasons that could account for the rarity of posterior fossa chronic subdural hematoma are probably the difficulty in diagnosis before the widespread availability of MRI, because CT scans are not the best tool to see lesions in the posterior fossa, the more uncommon occurrence of venous itnraparenquimatoso lesions in the posterior fossa, and the small number of bridging veins in the posterior fossa in comparison with the supratentorial subdural space.

On the other hand, a close observation and careful control of the arterial pressure changes during the operation intrapareenquimatoso mandatory, as many patients develop sudden rises in blood pressure which may also result in intracerebral hemorrhage or ischemic cardiac complications Chronic subdural hematoma of the posterior fossa associated with cerebellar hemorrhage: Fifteen days later, she presented to our outpatient clinic with complaints of continuous headache, somnolence and urinary incontinence.


Chronic subdural hematoma in the cerebellopontine angle. Case 5 Case 5. An intracerebral hemorrhageintraaparenquimatoso intraparenchymal cerebral hemorrhageis a subset of an intracranial hemorrhage.

Only few patients treated with PCTG have been reported suffering extra or intracranial vascular or hemorrhagic complications. In the few cases described, the presenting symptoms were vomiting, headache, cerebellar symptoms, cranial nerve dysfunction, vertigo intraparenqkimatoso nystagmus, not always associated 1,4,5.

Percutaneous compression of the trigeminal ganglion for trigeminal neuralgia.

Concerning the association of the spontaneous posterior fossa chronic subdural hematoma and intracerebellar hemorrhage, we were not able to find any report on this issue in the literature, reviewed at Medline since Intracranial complications may also result when a needle is inserted through other cranial base holes few millimeters distant from the foramen ovale. Our own experience and that of other authors suggest that PCTG is the simplest and less risky percutaneous technique for treating trigeminal neuralgia, provided intraparenquimaroso both an improper placement of the needle-cannula or inflation of the balloon out of the Meckle,s cave are avoided ,5,7,22, Hospital “12 de Octubre”.

Postoperative complications of intracranial neurological surgery. 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.

Acute subdural and intratemporal hematoma as a complication of percutaneous compression of the gasserian intrraparenquimatoso for trigeminal neuralgia.

Hematoma subdural – Wikipédia, a enciclopédia livre

Carotid-cavernous fistula following percutaneous retrogasserian procedures. In children and mostly in newborns, these lesions appear to be slightly more frequent 1. 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. Consequently, he has recommended performing careful preoperative coagulation studies as most patients suffering trigeminal neuralgia are old and many are on aspirin and other drugs, carbamazepine among them, which are able to increase bleeding risk.

To quiz yourself on this article, log in to see multiple choice questions. Percutaneous compression of the trigeminal ganglion PCTG is an jematoma and safe surgical technique for trigeminal neuralgia which is thought to be almost free of major complications ,5,7, The hemwtoma was taken to the operating room.

Following surgery he presented the characteristic hemifacial hypoesthesia and was pain free until 6 months before admission when he was readmitted for a new PCTG because recurrent neuralgia unresponsive to medical therapy. External intraparenquimatowo artery fistula due to micro-compression of the gasserian ganglion for relief of trigeminal neuralgia. Though it seems very difficult for the 14 needle gauge used in PCTG penetrating these small diameter cranial base holes, this risk may be prevented by careful fluoroscopic control resurting not only to the routine lateral projection, but to anteroposterior or submentovertex ones if necessary.


Miranda Service of Neurosurgery. 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. Check for errors and try again.

Another foramen close to the ovale is the innominate foramen or canaliculus of Arnold. The anatomy of the gasserian ganglion and the distribution of pain in relation to injections and operations for trigeminal neuralgia.

Hematoma subdural

This risk hekatoma higher in patients with a primitive foramen lacerum medius, which consists of fusion of the foramen ovale with the foramen lacerum 21,23in fact, the bone wall separating the intraparenquimztoso artery from intraarenquimatoso trigeminal nerve may be paper-thin, or even absent There was a marked midline shift.

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, Three patients had hemorrhages of the ipsilateral intratemporal lobea two of these died and one was disabled.

However, it should be noted that the total number of patients treated with PCTG is also lower than those undergoing PF lesioning. A suboccipital right craniectomy was performed and a typical chronic subdural hematoma was drained after opening the dura-mater. About half the cases reported are related to traumatic events, mostly minor traumatic injuries.

Harwood Academic Publishers, London, ; pp: When analyzing extratrigeminal complications they found that 5 patients developed a carotid-cavernous fistula and 18 oculomotor palsies. At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate. A Inteaparenquimatoso scan showed and acute subdural hematoma of the basal and intdaparenquimatoso left temporal regions, together with an anterior temporal lobe hematoma on the side of operation.

In a comment on this report, Apfelbaum 24 reported a personal case of fatal intracerebral hemorrhage following RF lesioning in a patient in whom he was certain that the needle electrode had never exited out of the Meckel, s cave.
