Is the retrograde access for endovascular treatment of a traumatic carotid cavernous fistula associated with dissection of the ipsilateral carotid possible?

This is a case demonstrating a combined traumatic lesion of the internal carotid artery (dissection and a carotid cavernous fistula [CCF]) in a patient who was beaten during a robbery and, while trying to escape, was hit by a vehicle. Endovascular approach for the treatment was chosen using the retrograde access from the vertebral artery to the cavernous sinus by posterior communicating (Pcom) artery due to the occlusion of the ipsilateral internal carotid. Because the artery access by the internal carotid was impossible, retrograde approach by vertebral artery and Pcom artery was done to treat the direct CCF.

How to differentiate intracranial atherosclerotic disease or vasospasms after mechanical thrombectomy. Be patient or vasodilator is the secret?

Here we describe a successful mechanical thrombectomy (MT) for acute large vessel occlusion in stroke treatment with one passage (thrombolysis in cerebral infarction, TICI 3). Immediately after the withdrawing of the stent retriever, a narrowing of the middle cerebral artery was diagnosed. The rate of vasospasms during this procedure can be as higher as 41% (range from 6-41%).

Republished: Spinal arteriovenous malformation without endovascular arterial access: is a combined neurosurgical approach and direct venous puncture an option?

This case report describes a combined neurosurgical and endovascular approach for the treatment of a conus medullaris arteriovenous malformation resulting in considerable improvement in the patient's neurological condition (modified Rankin Scale score 2).

The PHASES score: To treat or not to treat? Retrospective evaluation of the risk of rupture of intracranial aneurysms in patients with aneurysmal subarachnoid hemorrhage.

Background And Purpose: The PHASES score was formulated to predict the 5-year risk of rupture for intracranial aneurysms. We retrospectively analyzed all patients treated in our institution for aneurysmal SAH and applied the PHASES score to estimate the probable predicted risk of bleeding in this group of patients.

Methods: Between February 2015 and August 2018, all patients with aneurysmal SAH were retrospectively analyzed and the PHASES score was applied.

Follow-up of endovascular treatment of direct carotid-cavernous fistulas.

Introduction: Direct carotid-cavernous fistula (CCF) is a direct communication between the internal carotid artery (ICA) and the cavernous sinus. Some patients treated with detachable balloons develop pseudoaneurysms or present with a true aneurysm recanalization in the cavernous ICA with poorly known long-term radiological and clinical progression. The objective of the present study was to evaluate the long-term clinical and radiological progression of patients treated with detachable balloons.

Preliminary evaluation of the endovascular treatment of intracranial aneurysms with detachable coils in vigil patients.

Unlabelled: Endovascular treatment of intracranial aneurysms with coil embolization became the most important therapeutic option with better morbidity and mortality rates and quality of life. Following immobility, patients are treated with general anaesthesia.

Objective: To test viability of endovascular treatment on wake patients.

[Reference values for measures of blood flow velocities and impedance indexes in healthy individuals through conventional transcranial Doppler].

Objective: To establish reference values for measures of blood flow velocities and impedance indexes in healthy individuals through conventional transcranial Doppler (TCD) and to observe their variations in relation to the age and sex.

Method: 88 asymptomatic volunteers were examined without antecedents of cardiac, peripheral or cerebrovascular diseases. The TCD were accomplished by the same examiner.

[Dissecting aneurysm of the intracranial fenestrated vertebral artery submited to endovascular treatment: case report].

Dissecting aneurysms of the vertebral artery at its intracranial segment are uncommon lesions, mainly when associated to subarachnoid hemorrhage, being also rare fenestrations of the vertebral artery. They present high morbidity and mortality, with high rebleeding rate and difficulty of surgical approach. We present a 19 years old man who was victim of physical aggression in the occipto-cervical region, presenting subarachnoid hemorrhage and a dissecting aneurysm of the right vertebral artery, which had a fenestration, being submitted to endovascular treatment.

[Ischemic stroke after chemotherapy with cisplatin, etoposide and bleomycin: case report].

A 20-year-old man with a germ cell tumor who experienced an ischemic stroke as a complication of cisplatin/etoposide/bleomycin based chemotherapy is reported. The previously reported cases are reviewed as well as the different physiopathologic mechanisms associated with vascular toxicity of this regimen.

Endovascular treatment of intracavernous carotid aneurysm with hyperprolactinaemia.

A 42-year-old woman presented with headache, galactorrhoea, marked hyperprolactinemia and normal neurologic examination. CT, MR and MR-angiography showed an intracavernous carotid artery aneurysm with minimal displacement of the pituitary stalk. Treatment by embolisation using GDC coils allowed exclusion of the aneurysm.

[Orbital phlebography evaluation in 8 cases of Tolosa-Hunt syndrome].

Tolosa-Hunt syndrome (THS), or painful ophthalmoplegia is associated to a non-specific granulomatosis of unknown etiology, that involves the superior orbital fissure and its nervous and vascular structures. The clinical picture that responds to steroid therapy, is variable and is always associated with pain. Inflammatory conditions, tumors and aneurysms can produce similar symptoms.

Pathogenesis of uncus deformation and vertebral artery compression: histologic investigations of the uncus and dynamic angiography of the vertebral artery in the cadaveric cervical spine.

Twenty-one cervical spines were collected from fresh cadavers (12 male, nine female), their ages ranging from 10 to 90 years (mean 49.47). After removing muscle debris from the spines, they were mounted and tested on a device to passively reproduce the main movements of the spine.

[Computed tomography in methanol intoxication].

We had the opportunity to follow a methanol intoxication case with CT scans, at the 1st and 6th day after admission. Symmetrical putaminal and white matter lesions were seen on the last CT examination, and occurred with the worsening of neurological manifestations, despite the appropriated treatment. The CT demonstration of brains lesions disclosed the toxic effect of the methanol and could be a guideline to the neurological prognosis.
