1/162. Compression of the visual pathway by anterior cerebral artery aneurysm.Visual failure is an uncommon presenting symptom of an intracranial aneurysm. It is even more uncommon in aneurysms arising from the anterior cerebral artery (ACA). We presented 2 patients with an aneurysm of the A1 segment of the anterior cerebral artery causing visual field defects. One patient presented with a complete homonymous hemianopia due to compression of the optic tract by a giant aneurysm of the proximal left A1 segment. The second patient had an almost complete unilateral anopia caused by compression of the optic nerve and chiasm by an aneurysm of the distal part of the A1 segment with a small chiasmatic hemorrhage and ventricular rupture.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/162. Resolution of third nerve paresis after endovascular management of aneurysms of the posterior communicating artery.The effect of endovascular treatment on the recovery of neural function in patients with third nerve palsy caused by an aneurysm of the posterior communicating artery is poorly documented. We report three cases in which third nerve paresis resolved completely within 2 to 3 weeks of endovascular occlusion of a posterior communicating artery aneurysm.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
3/162. Endosaccular aneurysm occlusion with Guglielmi detachable coils for obstructive hydrocephalus caused by a large basilar tip aneurysm. Case report.The authors present the case of a 60-year-old man with obstructive hydrocephalus caused by a large basilar artery tip aneurysm, in whom direct surgical clipping of the aneurysm neck was considered hazardous. After endosaccular aneurysm occlusion, his symptoms (headache, intellectual impairment, and gait disturbance) and ventricular dilation immediately improved without placement of a ventricular shunt. To the authors' knowledge, this is the first case of its kind treated solely endovascularly.- - - - - - - - - - ranking = 0.16666666666667keywords = artery (Clic here for more details about this article) |
4/162. Multifocal dural enhancement associated with temporal arteritis.OBJECTIVE: To report the association of temporal arteritis and enhancement of the dura mater and temporalis muscle. DESIGN AND methods: A single patient with a complaint of headache and diplopia was studied. SETTING: Academic medical center. PATIENT: A 69-year-old man presented with lateral rectus weakness, temporal artery tenderness, and an erythrocyte sedimentation rate of 65 mm/h. INTERVENTION: biopsy of temporal artery and dura mater. MAIN OUTCOME MEASURES: Brain magnetic resonance imaging and pathological findings. RESULTS: magnetic resonance imaging of the brain showed multifocal dural enhancement and enhancement of the temporalis muscles. The temporal artery showed a necrotizing vasculitis and the dura showed perivascular inflammatory cells. CONCLUSION: It is proposed that the temporal arteritis caused the multifocal dural enhancement and temporalis muscle enhancement on magnetic resonance imaging.- - - - - - - - - - ranking = 0.5keywords = artery (Clic here for more details about this article) |
5/162. Central retinal artery occlusion associated with head or neck pain revealing spontaneous internal carotid artery dissection.PURPOSE: To report two cases of head or neck pain and central retinal artery occlusion associated with spontaneous dissection of the ipsilateral internal carotid artery. methods: case reports. RESULTS: We describe two cases of sudden visual loss caused by central retinal artery occlusion. Both cases were preceded by ipsilateral headaches or neck pain and tinnitus. The patient had no other neurological signs or history of trauma. In both cases, cerebral angiography revealed ipsilateral internal carotid artery dissection. CONCLUSION: Ipsilateral headache or neck pain with tinnitus preceding central retinal artery occlusion is highly suggestive of internal carotid artery dissection. early diagnosis and treatment may reduce the risk of hemispheric stroke.- - - - - - - - - - ranking = 24.056308651581keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
6/162. Guglielmi detachable coil treatment of a partially thrombosed giant basilar artery aneurysm in a child.We report a partially thrombosed giant of the aneurysm basilar artery with prominent mass effect, diagnosed in an 11 year-old child who presented with neurological deficits due to brain stem compression. After the patent portion of the aneurysm was embolised with Guglielmi detachable coils, remarkable clinical improvement occurred. Angiography demonstrated complete occlusion of the aneurysm and MRI revealed dramatic shrinkage of the aneurysm at 6-month and 1-year follow-up.- - - - - - - - - - ranking = 0.83333333333333keywords = artery (Clic here for more details about this article) |
7/162. Unruptured cerebral aneurysm producing a thunderclap headache.A sudden and severe headache is the most common presentation of an acutely ruptured cerebral aneurysm. A similar headache in the absence of subarachnoid blood has rarely been ascribed to an unruptured cerebral aneurysm, but may result from acute aneurysm expansion and indicate a high risk of future rupture. We present a patient who developed a sudden, severe, "thunderclap" headache, with no associated neurological deficit. Computed tomogram and lumbar cerebral spinal fluid obtained 5.5 hours after headache onset were negative for subarachnoid hemorrhage. The patient underwent cerebral angiography which revealed a posterior communicating artery aneurysm with an associated daughter aneurysm. craniotomy and clip obliteration of the aneurysm were performed. The aneurysm dome was very thin and there was no evidence of recent or old hemorrhage. A "thunderclap" headache without subarachnoid hemorrhage may be an important harbinger of a cerebral aneurysm with the potential for future rupture. Early recognition and neurovascular imaging of aneurysms presenting in this rare fashion are warranted.- - - - - - - - - - ranking = 0.16666666666667keywords = artery (Clic here for more details about this article) |
8/162. Limb-threatening ischemia due to ergotamine: case report with angiographic evidence.A 29-year-old woman presented with severe leg pain that had lasted for several weeks. During that period, she had taken painkillers in order to achieve sleep. In the week before she was admitted to hospital, she had noticed numbness and a cold feeling below her knees. There were no arterial pulsations below her groin, the skin of her legs being cold and pale. She had a history of chronic daily headache and had ingested Cafergot compound corresponding to ergotamine 2 to 3 mg daily for the previous 2 or 3 months. Angiography demonstrated severe narrowing of both superficial femoral arteries for a distance of about 5 to 6 cm and a subtotal stenosis of the right popliteal artery. After discontinuation of ergotamine, the patient's symptoms gradually disappeared within a few days. Angiography was repeated 2 days after the first examination and demonstrated regression of the spasms in the femoral arteries and reestablished flow in the distal vessels. ergotamine tartrate can induce life-threatening ischemia of an extremity. Discontinuation of ergotamine is usually sufficient to reverse the ischemia, however, intravenous infusion of sodium nitroprusside may occasionally be necessary to avoid limb amputation.- - - - - - - - - - ranking = 0.16666666666667keywords = artery (Clic here for more details about this article) |
9/162. Orbital drainage from cerebral arteriovenous malformations.OBJECTIVE: To describe the neuro-ophthalmic findings in patients with orbital drainage from cerebral arteriovenous malformations (AVMs). methods: We reviewed the records of 100 consecutive adult patients with cerebral AVMs who presented to our institution during a 4-year period. All patients with orbital drainage were identified, and their neuro-ophthalmic evaluations were reviewed. RESULTS: Three patients (3%) were identified with orbital drainage from a cerebral AVM. The first patient presented with typical chiasmal syndrome (reduced visual acuity, bitemporal hemianopia, and optic atrophy). magnetic resonance imaging demonstrated a large left temporal and parietal lobe AVM with compression of the chiasm between a large pituitary gland and a markedly enlarged carotid artery. The second patient presented with headaches and postural monocular transient visual obscurations. Examination revealed normal visual function with minimal orbital congestion and asymmetrical disc edema, which was worse in the left eye. magnetic resonance imaging revealed a large right parietal and occipital lobe AVM without mass effect or hemorrhage and an enlarged left superior ophthalmic vein. The third patient had no visual symptoms and a normal neuro-ophthalmic examination; a right parietal lobe AVM was discovered during an examination for the cause of headaches. CONCLUSION: Orbital drainage from cerebral AVMs is rare. Manifestations may include anterior visual pathway compression, dilated conjunctival veins, orbital congestion, and asymmetrical disc swelling.- - - - - - - - - - ranking = 3.2699488549877keywords = carotid, carotid artery, artery (Clic here for more details about this article) |
10/162. 'Herald hemiparesis' of basilar artery occlusion: early recognition by transcranial Doppler ultrasound.A transient hemiparesis may be ocassionally present at an early stage of the thrombosis of the basilar artery (herald hemiparesis). We report on one of these cases and the valuable role of transcranial Doppler ultrasound (TCD) to the early detection of the stroke-in-evolution. TCD in the emergency room is a good tool to assess a basilar occlusion, searching for direct (absence of signal at the basilar artery) and indirect (reversal flow of the pre-communicating segment the of posterior cerebral artery through the posterior communicating artery) signs. Early recognition and treatment of this condition could avoid the development of the full syndrome of the basilar artery thrombosis.- - - - - - - - - - ranking = 1.5keywords = artery (Clic here for more details about this article) |
