Trochlear nerve palsy after repeated percutaneous balloon compression for recurrent trigeminal neuralgia: J Neurosurg ; Needle for use during percutaneous compression of gasserian ganglia for trigeminal neuralgia.

Hemorragia intracerebral

The 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.

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 intrapaenquimatoso inflation of the balloon out of the Meckle,s cave are avoided ,5,7,22, About half the cases reported are related to traumatic events, mostly minor traumatic injuries.

Churchill Livingstone, New York ; pp: 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. 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 All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.


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, Current diagnosis and treatment in neurology. At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate.

Three patients had hemorrhages of the ipsilateral intratemporal lobea two of these died and one was disabled. To conclude, we have reported the first case of a fatal intracranial hemorrhagic complication of PCTG.

Computed tomography of posterior fossa. Dangerous rises in blood pressure upon heating of trigeminal rootlets; increased bleeding times in patients with trigeminal neuralgia. The remaining 15 intracerebral hemorrhages occurred at a site unrelated with the needle; eight intraparenquimxtoso these hfmatoma died, and 4 developed severe disability. Eur J Radiol ; Balloon compression rhizotomy in surgical management of trigeminal neuralgia.

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 into the Meckel,s cave before inflating the balloon 4,16, Clin Neurosurg ; Reiwlta et al, 18 reported a patient who developed an intrapadenquimatoso 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 intraparemquimatoso after puncture.

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. The anatomical structures at risk of inteaparenquimatoso by misplaced needle or catheter and some relevant thecnical details aimed to prevent extratrigeminal complications related with this and other percutaneous trigeminal lesioning procedures are analyzed.


heamtoma The other half has a variety of causes minor trauma not recalled by the patient, anticoagulation therapy, blood clotting disorders and intracranial hypotension or no cause that could be found at all. Case report 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.

The patient was taken to the operating room. The mechanism of blood pressure elevation during gasserian ganglion heating is unknown, but it has been related with pain felt by the unanesthetized patient during the procedure.

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 intraparenquimatsoo blood pressure which may also result in intracerebral hemorrhage or ischemic cardiac complications Percutaneous compression trigeminal ganglion.

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. Cranial anatomy and surgical approaches.

Clinical presentation of these lesions varies widely depending on the acute or chronic stage of the bleeding.
