Spontaneous posterior fossa subdural hematoma as a complication of anticoagulation. On opening ijtraparenquimatoso dura, the old, liquefied blood gushed out, suggesting hypertension in the posterior fossa.

Hemorragia intracerebral – Wikipédia, a enciclopédia livre

Postoperative transient diplopia occurring in patients showing a pear-shaped balloon during surgery and satisfactory functional result have been attributed to IV or VI nerve compression against the tentorium o within the cavernous sinus 14,17, Percutaneous trigeminal nerve compression.

There seems to be no difference in the mechanism of occurrence of supra and infratentorial chronic subdural hematoma, with the supposed starting point being the mingling of cerebrospinal fluid with blood in a small subdural hematoma. 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.

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

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. In addition, a tortuous carotid artery may pass directly over the foramen ovale making it impossible reaching the ganglion without puncturing the artery Simultaneous supra- and infratentorial chronic subdural hematoma.

In a review of cases from Sambasivan 2none in the posterior fossa was reported, and Tsai et al. ICH on warfarin Case 1: 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 Fifteen days later, she presented to our outpatient clinic with complaints of continuous headache, somnolence and urinary incontinence.

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.

You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Services on Demand Journal. Focal intracranial hemorrhages occurred in 19 patients. J Neurosurg ; Clin Neurosurg ; The rarity of these lesions precludes treatment protocols, but probably the treatment should not differ from that of chronic supratentorial hematomas, with correction of the coagulation profile if necessary and surgical drainage.


The symptoms of brain stem compression or cerebellar signs could suggest the presence of a posterior fossa lesion, a rare lesion even with the use of anticoagulation. Received 4 Julyreceived in final form 27 August Accepted 1 October 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 intraparenqui,atoso prevented by injecting lidocaine into the Meckel,s cave before inflating the balloon 4,16, A CT scan showed and acute subdural hematoma of the basal and convexity left temporal regions, together with an anterior temporal lobe hematoma on the side of operation.

As stated above we never stopped PCTG because the occurrence of arterial bleeding through the needle, even if intraparenquimayoso of carotid origin as it invariably disappeared following needle replacement excepting in the patient in whom repeated puncture of the foramen ovale always resulted in brisk and pulsatile arterial intraparenqiumatoso most likely arising from the carotid artery.

Posterior fossa subdural hematoma. External carotid artery fistula intraparenquimtoso to micro-compression of the gasserian ganglion for relief of trigeminal neuralgia. J Comp Assist Tomogr ;4: Chronic subdural hematoma in the cerebellopontine angle. Support Radiopaedia and see fewer ads. In patients on anticoagulation therapy, intracranial bleeding should always be suspected in the presence of neurological symptoms.

The remaining 15 intracerebral hemorrhages occurred at a site unrelated with the needle; eight of these patients died, and 4 developed severe disability. When it is placed too medial it may go directly into the cavernous sinus and the internal carotid artery may be punctured.

Harwood Academic Publishers, London, ; pp: 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. Articles Cases Courses Quiz. Carotid-cavernous fistula following percutaneous retrogasserian procedures.


Chronic subdural hematoma of the posterior fossa associated with cerebellar hemorrhage: However, the exam of the x-ray obtained during balloon inflation showed a cylindrical shape revealing its location out of the Meckel, cave. About half the cases reported are related to traumatic events, mostly minor traumatic injuries. The patient was taken to the operating room.

The actual mechanism for intracranial bleeding resulting from percutaneous procedures on the trigeminal ganglion seems to be a direct vascular injury by a misplaced needle 26,27 or the inflated balloon. Case 5 Case 5. Eur J Radiol ; Current diagnosis and treatment in neurology.

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.

Hematoma subdural

Trigeminal nerve compression for neuralgia. At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate. Acta Neurochir Wien ; Occasionally we intraparensuimatoso observed another atypical balloon shapes such as oval, irregular or round which resulted in a good functional hemxtoma as revealed by long-lasting pain control with the corresponding hemifacial hipoesthesia, despite that the nipple intraparenqyimatoso through the poros trigemini and providing the typical pear-shape of a properly placed balloon was not observed.

Another CT scan was performed and showed hydrocephalus, and a ventriculoperitoneal shunt was inserted Fig 1. 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, Fatal complication of percutaneous microcompression of the gasserian ganglion.

CV Mosby, ; pp: There was a marked midline shift.
