Balloon compression rhizotomy in surgical management of trigeminal neuralgia. It seems very likely that with this trochar the risk of piercing the dura propia of the cave actually decreases. When analyzing extratrigeminal complications they found that 5 patients developed a carotid-cavernous fistula and 18 oculomotor palsies. Complications of percutaneous rhizotomy and microvascular decompression operations for facial pain.

Kuether el al, 13 reported the case of a year-old man who developed a direct high-flow carotid cavernous fistula which required endovascular treatment; the Fogarty catheter was apparently inflated into the lumen of the internal carotid artery despite that no arterial hemorrhage was noted during the procedure.

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.

Hematoma subdural – Wikipédia, a enciclopédia livre

We indirectly assumed that the balloon was inside the Meckel,s cave in these instances, but we have not an explanation for these atypical intraparenwuimatoso Log in Sign up. We describe a case in a woman. 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.

Hospital 12 de Octubre.

Hospital “12 de Octubre”. We describe the case of a patient who developed a fatal intratemporal intraparsnquimatoso subdural hemorrhage following PCTG and discuss the possible causes of technical failure with the aim of preventing such a dreadful complication.

Radiofrequency rhizotomy for trigeminal and other cranial neuralgias. Dangerous rises in blood pressure upon heating of trigeminal rootlets; increased bleeding times in patients with trigeminal neuralgia.

You can also scroll through hmeatoma with your mouse wheel or the keyboard arrow keys. 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.

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. Cranial anatomy and surgical approaches. Another foramen close to the ovale is the innominate foramen or canaliculus of Arnold. Changes in the systemic blood pressure and the cardiac rhythm induced by therapeutic compression of the trigeminal ganglion.

Percutaneous trigeminal nerve compression. On opening the dura, the old, liquefied blood gushed out, suggesting hypertension in the posterior fossa. Surg Neurol ; Abbreviations used in this paper. The remaining 15 intracerebral hemorrhages occurred at a site unrelated with the needle; eight of these patients died, and 4 developed severe disability. Clin Neurol Neurosurg ; 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.

The postoperative CT scan was unremarkable. 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.

Case report and pathogenic considerations. 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 most likely explanation for bleding was Fogarty catheter slippage and prolonged inflation of the balloon out of Meckel,s cave due to failure of the surgeon to recognize its atypical shape.

Basal foramina and canals. About half the cases reported are related to traumatic events, mostly minor traumatic injuries. Intraparenqhimatoso complication of percutaneous microcompression of the gasserian ganglion. Computed tomography of posterior fossa. 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.

J Comp Assist Tomogr ;4: An intracerebral hemorrhageor intraparenchymal cerebral hemorrhageis a subset of an intracranial hemorrhage. Case 10 Case Needle for use during percutaneous compression of gasserian ganglia for trigeminal neuralgia.

Apart from intratrigeminal side effects such as transient hemifacial sensory loss, dysesthesia and masticatory weakness, extratrigeminal complications including oculomotor nerve palsies, extracranial arteriovenous fistula or carotid cavernous fistula have been occasionally intraparenquimatoxo. Only few patients treated with PCTG have been reported suffering extra or intracranial vascular or hemorrhagic complications. Clinical presentation of these lesions varies widely depending on the acute or chronic jntraparenquimatoso of the bleeding.

Hematoka normal coagulation studies, the absence of arterial pressure changes during balloon inflation and the location of hematomas close to the surgical field make almost certain that bleeding was related to a local vascular injury in our patient. 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 Another CT scan was performed and showed hydrocephalus, and a ventriculoperitoneal shunt was inserted Fig 1.

A suboccipital right craniectomy was performed and a typical chronic subdural hematoma was drained after opening the dura-mater. Apart from hemorrhagic strokes, other vascular accidenta related to the electrode were one arterial puncture followed by transient hemiparesis and 5 arterial subsrachnoid hemorrhages; three out of these last patients died and two recovered.

hematoma intraparenquimatoso

intraparenqiimatoso Sweet and Poletti 27 made a survey of complications of percutaneous RF trigeminal rhizotomies and recruited data from 29 neurosurgical units totalling over cases, mostly undergoing RF lesioning. Edit article Share article View revision history. The diagnosis of chronic lesions in the posterior fossa is very difficult.
