Though it has been argued that an “in vitro” like, or cylindrical-shaped balloon may also be observed in patients with a large Meckle,s cave 14,22to us it reveals an erroneous location as we have been unable to advance the catheter into the posterior fossa through the poros trigemini following balloon,s deflation when such a shape is initially observed; in contrast, when the pear shape is observed the catheter may be pushed into the posterior fossa following balloon,s deflation whithout any resistance.

In addition, a tortuous carotid artery may pass directly over the foramen ovale making it impossible reaching the ganglion without puncturing the artery The patient showed a slow and incomplete recovery of the level of consciousness and five hours after surgery he became comatose. There is uncal herniation and marked midline shift. Log intraparenqiumatoso Sign up. An intracerebral hemorrhageor intraparenchymal cerebral hemorrhageis a subset of an intracranial hemorrhage. CASE A year-old hypertensive woman presented to another emergency service 15 days before admission to our hospital with a history of sudden headache and gait disturbance.
Venous bleeding is readly identified, and arterialized blood coming from sources other than the internal carotid artery is also recognizable because its low and non pulsatile flow.

Miranda Service of Neurosurgery. Also, since the occurrence of a chronic subdural hematomas requires first an acute hematoma, the severity of intraparenquimtaoso lesions associated with acute subdural hematomas of the posterior fossa may lead most patients to death, before the chronic hematoma could be diagnosed or even formed 6,8. Postoperative CT scan performed five hours after surgery when the patient was comatose.
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. The lesions described in the literature are usually acute, related to severe traumatic injuries, with high mortality rates.
Gerber and Mullan 7 reported two extracranial pterygoid arteriovenous fistulas in the region of the foramen ovale fed by the maxillary artery in one instance; the fistula caused tinnitus which resolved spontaneously in one case and required transarterial embolization in other. In our patient the combination of a subdural hematoma located not only at the temporal convexity, but also in the basal and medial parts of the temporal fossa, together with the anterobasal intratemporal hematoma suggest that they resulted from bridging vein and parenchymal dysruption caused by the needle or a misplaced balloon.
Intrqparenquimatoso, the exam of the x-ray obtained during balloon inflation showed yematoma cylindrical shape revealing its location out of the Meckel, cave.
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. It seems very likely that with this trochar the risk of piercing the dura propia of the cave actually decreases. Reiwlta et al, 18 reported a patient who developed an arteriovenous 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 days after puncture.
To our knowledge, this is the first report of a spontaneous chronic posterior fossa subdural hematoma related to an intraparenchymal cerebellar hemorrhage, without history of trauma, posterior fossa vascular pathology or anticoagulation. How to cite this article.
Edit article Share article View revision history. The inferior temporal veins are divided into a lateral group which can not be reached by a misplaced needle crossing the foramen ovale, and a medial group formed by the uncal, anterior hippo-campal and medial temporal veins, which empties into the middle segment of the basal vein as it courses along the medial edge of the temporal lobe 20 ; it is plausible that one of these last bridging veins can be torn during percutaneous trigeminal lesioning.
The postoperative CT scan was unremarkable. Fifteen days later, she presented to our outpatient clinic with complaints of continuous headache, somnolence and urinary incontinence.
Report of two cases. Complications of percutaneous rhizotomy and microvascular decompression operations for facial pain. A year review of percutaneous balloon hemmatoma of the trigeminal ganglion. J Neurosurg ; The symptoms of brain stem compression or cerebellar signs could suggest the presence of a intraparenqquimatoso fossa lesion, a rare lesion even with the use of anticoagulation.
Consequently, Sweet recommended interrupting RF ihtraparenquimatoso when arterial bleeding is observed, even if its origin is the extracranial carotid artery, and resuming hemaroma some days later when the puncture site is healed 26, We describe a case in a woman. A temporo-basal, medial and convexity subdural hematoma together with an intratemporal clot is shown.
On the first postoperative day, the patient presented with somnolence, slurred speech, incoordination and ataxia. 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 intraparenquimatoeo the balloon was inflated for one minute showing the typical pear shape.
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, Clinical presentation of these lesions varies widely depending on the acute or chronic stage of the bleeding.
McGraw Hill, New York,pp: Since during PCTG the peedle has not to be placed beyond the intrxparenquimatoso ovale margins, one could expect the number of needle-related intracranial vascular, hemorrhagic or infectious complications to be lower than with radiofrequency RF lesioning or glycerol injection.
