Long-term Outcomes of Carotid Artery Stenting for Radiation-Associated Stenosis.

Background: In Taiwan, the prevalence of head and neck cancer is relatively high. Because radiation-associated carotid stenosis is a significant risk factor for stroke, carotid artery stenting (CAS), instead of carotid endarterectomy, is indicated in patients with radiation-associated carotid stenosis. We sought to evaluate the effect of neck radiotherapy (XRT) on the long-term outcome of patients undergoing CAS.

Comparison of carotid artery stenting performance between cardiologists and neuroradiologists: one medical center's experience.

Purpose: To report the experience of carotid artery angioplasty with stenting (CAS) by cardiologists (CV) and neuroradiologists (NR) in an area with less incidence of extracranial artery stenosis.

Methods: From 1999 to 2008, 210 patients with 231 stents were collected by claim records from the administrative office and reviewed by one independent neurologist. Outcome measures were peri-procedural adverse events (AE), restenosis and recurrent ipsilateral stroke (RS) rate, categorized into treatment groups by either CV or NR.

Intra-arterial thrombolytic therapy for acute intracranial large artery occlusive disease in patients selected by magnetic resonance image.

Background And Purpose: We reported an experience of intra-arterial thrombolysis (IAT) study triaged by emergent MRI.

Methods: Patients were recruited if vascular occlusions were identified by emergent MRA. Urokinase was infused hyperselectively within 6h after onset to a maximum dose of 900,000IU or recanalization achieved with mechanical thrombus disruption.

Effect of lipid-lowering therapy on the progression of intracranial arterial stenosis.

Objectives: Intracranial arterial stenosis (IAS) is a severe disease with a high recurrent stroke rate even under the best medical treatment. Statins have been demonstrated to prevent stroke and to slow or halt atherosclerosis progression. This study was performed to observe the effect of atorvastatin on the progression of IAS, explore the factors associated with atherosclerosis regression and the recurrent rate of stroke.

Factors associated with brainstem congestive encephalopathy in dural arterio-venous fistulas.

Objectives: Cranial dural arterio-venous fistulas (DAVFs) are unique neuro-vascular entities that represent 10-15% of all intra-cranial arterio-venous lesions. This study describes the clinical characteristics and neuro-imaging findings of patients with posterior fossa DAVFs.

Methods: Twenty adult patients with posterior fossa DAVFs were enrolled in this 5-year retrospective study.

Transient contrast encephalopathy after carotid artery stenting mimicking diffuse subarachnoid hemorrhage: a case report.

Several types of brain injury incurred during carotid artery stenting (CAS), such as embolic injury, hemodynamic events, and hemorrhage. Rapid differential diagnosis is important for decision making, and may help to avoid subsequent complications. Here, we describe a case with severe triple vessel coronary artery disease, who underwent right coronary artery (RCA) stenting and ad hoc left CAS.

Combination of olfactory course anterior cerebral artery and accessory middle cerebral artery (MCA) with occluded in situ MCA and related moyamoya phenomenon.

We describe a rare case of congenital persistence of a primitive olfactory anterior cerebral artery in association with an ipsilateral accessory middle cerebral artery. The normally and anatomically positioned, or in situ, middle cerebral artery was occluded. This, along with a well-developed anastomotic network of lenticulostriate artery domains and leptomeningeal collaterals suggested a moyamoya phenomenon.

Cerebellar hemorrhage and subsequent venous infarction followed by incomplete transvenous embolization of dural carotid cavernous fistulas: a rare complication: case report.

Endovascular therapy for dural carotid cavernous fistulas (CCFs) is generally accepted to be safe and effective. The authors report a rare complication of hemorrhage and subsequent venous infarcts of the pons and cerebellum after transvenous embolization. This 41-year-old man presented with a severe left frontal headache, congestion of the left conjunctiva, blurred vision, and photophobia.

Refractures in cemented vertebrae after percutaneous vertebroplasty: a retrospective analysis.

Percutaneous vertebroplasty is an efficient procedure to treat pain due to osteoporotic vertebral compression fractures. However, refracture of cemented vertebrae occurs occasionally after vertebroplasty. It is unclear whether such fractures are procedure-related or part of the natural course of osteoporosis.

Rapid regrowth of a successfully coiled traumatic pericallosal aneurysm.

Regrowth of an intracranial aneurysm is a known complication of endovascular coiling. We report a patient with a traumatic pericallosal aneurysm which was initially treated successfully with endovascular coiling. Six-month follow-up angiography showed aneurysm regrowth with migration of the coils.

Multiple intracranial arterial stenoses in association with thyrotoxicosis: a case report.

A 26-year-old young man, had Graves' disease in hyperthyroid state, presented with frequent episodic transient left hemiparesis and mild slurred speech lasting for few minutes to 2 hours for one month. Infarction at posterior limb of right internal capsule was found on brain MRI. Angiography revealed multiple intracranial arteries stenoses around the circle of Willis.

Severe acute respiratory syndrome: prognostic implications of chest radiographic findings in 52 patients.

Purpose: To retrospectively assess prognostic implications of radiographic findings in severe acute respiratory syndrome (SARS).

Materials And Methods: Radiographic findings were reviewed by two radiologists for 52 patients with SARS. On each radiograph, each lung was separated into upper, middle, and lower zones.

Trauma-induced ascending pharyngeal artery-internal jugular vein fistula: case report.

Background: Ascending pharyngeal artery-internal jugular vein fistulas are rare. Only 2 spontaneous cases and one complicated neck surgery have been reported. We describe a trauma-induced case.

Development of intracranial complications following transoral stab wounds in children. Report of two cases.

Sharp penetrating trauma to the skull and brain is uncommon in children. The related pediatric literature consists mainly of cases involving penetrating stab wounds to the face or scalp resulting from assaults or accidents. Herein, we present two cases of perioral intracranial penetration.
