Hemorragia intracerebral

Changes in arterial pressure were not recorded during the whole procedure. 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 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.

The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. CV Mosby, ; pp: Thank you for updating your details. 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.

Subarachnoid hemorrhage and “normal pressure hydrocephalus”.

inhraparenquimatoso To conclude, we have reported the first case of a fatal intracranial hemorrhagic complication of PCTG. 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 diagnosis of chronic lesions in the posterior fossa is very difficult. inyraparenquimatoso

Acta Neurochir Wien ; Spaziante el al, 24 reported the occurrence of subarachnoid hemorrhage filling the basal and sylvian cisterns in a 62 year old man who underwent PCTG; normal pressure hydrocephalus developed as a consequence, and the patient eventually died following various complications; the surgical procedure was apparently correct as the needle did not penetrate beyond the foramen ovale and the inflated balloon did not move out of the Meckel,s cave; in addition, the functional result was excellent indicating an appropriate compression of the gasserian ganglion, and both normal coagulation studies and cerebral angiography excluded an alternative cause for SAH in this patient; since he did not show arterial pressure rises during the procedure, the authors attributed subarachnoid hemorrhage to piercing of the dura at the intracranial entry point with subsequent hemorrhagic extension into the CSF spaces.


Radiology of the Skull and Brain. 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.

Basal foramina and canals. Carotid-cavernous fistula following percutaneous retrogasserian procedures. Acute subdural and intratemporal hematoma as a complication of percutaneous compression of the gasserian ganglion for trigeminal neuralgia. 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, Support Radiopaedia and see fewer ads.

However, it should be noted that the total number of patients treated with PCTG is also lower than those undergoing PF lesioning.

However, the exam of the x-ray obtained during balloon inflation showed a cylindrical shape revealing its location out of the Meckel, cave. Spontaneous posterior fossa subdural hematoma as a complication of anticoagulation. 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, 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.

Postoperative CT scan performed five hours after surgery when the patient was comatose. Only few patients treated with PCTG have been reported suffering extra or intracranial vascular or hemorrhagic complications.

Summary 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.

Carotid-cavernous fistula following percutaneous trigeminal ganglion approach.

Abbreviations used in this paper. Case report and pathogenic considerations. 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 hemtoma Meckle,s cave are avoided ,5,7,22, ICH on warfarin Case 1: Percutaneous microcompression of intraparenqiumatoso trigeminal ganglion for trigeminal neuralgia.

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.

Check for errors and try again. Subdural hematomas of the posterior fossa are very rare in adults 1.

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 hematima they resulted from bridging vein and parenchymal dysruption caused by the needle or a misplaced balloon.

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.

The patient showed a slow and incomplete recovery of the level of consciousness and five hours after surgery he became comatose. 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 intraparenauimatoso pushed into the posterior fossa following balloon,s deflation whithout any resistance.

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 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 hwmatoma which may also result in intracerebral hemorrhage or ischemic cardiac intraparenquimatosoo
