Stroke death in patients receiving radiation for head and neck cancer in the modern era
ConclusionsWhile radiotherapy for head and neck cancer increases the hazard of stroke death, this is reduced in the modern era and remains a very small absolute risk.

Cancers, Vol. 12, Pages 616: Radiotherapy Is Associated with an Accelerated Risk of Ischemic Stroke in Oral Cavity Cancer Survivors after Primary Surgery
In conclusion, radiotherapy increased the risk of ischemic stroke by 68% and also accelerated the onset of stroke in long-term OCC survivors after primary surgery compared with matched normal controls. Secondary prevention should include stroke as a late complication in OCC survivorship programs.

Massive Epistaxis from Internal Carotid Pseudoaneurysm during Acute Ischemic Stroke in a Patient with Nasopharyngeal Carcinoma.
CONCLUSION: Carotid blowout syndrome in NPC patients during acute ischemic stroke warrants further cervical angiographic study. Endovascular treatment provides immediate hemostasis and obliteration of ICA pseudoaneurysm. PMID: 26077184 [PubMed - indexed for MEDLINE]

Risk of Stroke After Definitive Radiotherapy —Cause for Concern or Modest Risk?
With the rapidly increasing prevalence of oropharyngeal squamous cell carcinoma (OPSCC), largely driven by the human papillomavirus (HPV) epidemic, and with relative equipoise between radiation-based and surgery-based treatment protocols, there has been renewed interest in describing differences in functional outcomes between the 2 treatment modalities. Radiation is theoretically related to stroke risk due to carotid artery intimal injury, which could lead to the development of atherosclerosis. Both carotid artery stenosis and carotid intima-medial thickness have been shown to be associated with radiation therapy providing...

The Syndrome of Stroke-like Migraine Attacks After Radiation Therapy Associated With Prolonged Unresponsiveness in an Adult Patient
Conclusions: Reduced level of consciousness of such severity and duration as observed here has not previously been described in SMART syndrome. This report, however, suggests that an excellent prognosis can be expected even in cases of prolonged unresponsiveness. The pathogenic mechanisms of SMART syndrome remain unclear, but may involve pathways common to both migraine and epilepsy.

Teaching NeuroImages: Radiation-associated symptomatic carotid artery disease with ipsilateral radiodermatitis
A 68-year-old man with a history of squamous cell carcinoma of the tongue treated with external beam radiation therapy in 2007 presented in 2013 with acute onset expressive aphasia and right lower facial weakness. MRI confirmed an acute infarct in the left frontal cortex. CT angiography revealed occlusion vs critical stenosis of the left internal carotid artery, new from 2007. Examination of the patient's neck revealed ipsilateral radiodermatitis (figure). Therapeutic neck irradiation has been associated with accelerated atheromatous disease, carotid artery stenosis, and increased risk of stroke.1,2 Ipsilateral radiodermat...

Stroke After Radiation Therapy for Head and Neck Cancer: What Is the Risk?
A retrospective population-based cohort study was conducted to determine the risk of ischemic stroke with respect to time, associated with curative radiation therapy in head and neck squamous cell carcinomas (HNSCC).

Status Epilepticus in Patients with SMART (P5.012)
CONCLUSIONS We describe three patients with SMART presenting with SE. Our cases raise the concern that SMART is not necessarily a migraine phenomenon but can be a form of focal SE associated with stroke-like symptoms. In patients with radiographic suspicion of SMART we suggest a low threshold for vEEG monitoring and aggressive anti-epileptic management.Disclosure: Dr. Fan has nothing to disclose.

E-067 Endovascular Approach in the Repair of the Middle Cerebral Artery Aneurysm Including Those with Wide Neck and Complex in Morphology-A Case Series
ConclusionsEndovascular repair of the MCA aneurysm inclosing those with wide neck and complex are not only safe and feasible, but associated with high long-term functional outcome. Therefore, endovascular options must be offered to patients prior to surgical clipping of a MCA aneurysm. Further study may be warranted.DisclosuresY. Lodi: None. V. Reddy: None.

NAMPT as a Dedifferentiation-Inducer Gene: NAD+ as Core Axis for Glioma Cancer Stem-Like Cells Maintenance
Conclusion and Perspectives Gliomas are the most prevalent primary brain cancer in adults and include a broad category of tumors including astrocytoma, oligodendroglioma, and GBM. Regardless of tumor aggressiveness, malignancy, and infiltration, these glia-derived tumors rarely exceed a median survival time of 12–14 months. Driven by the infiltrative nature of these tumors, the clinical approach is difficult and relapses often occur with fatal consequences. These unsuccessful attempts to control glioma's fate have fostered research looking for more effective therapies. (GSCs) are a small subset of CD133&#...

Carotid Sparing Conformal Radiotherapy for Early Larynx Cancer
Parallel opposed lateral (POL) portals have been adopted as the mainstay radiation therapy technique for early-stage carcinoma of the glottis. Although the use of POL has been associated with excellent control rates and tolerability, the partial inclusion of carotid arteries (CAs) in the high dose regions of the fields has been shown to lead to an increased long-term risk of carotid stenosis and hemorrhagic stroke. Many researchers have proposed the utilization of three-dimension conformal therapy (3DCRT) or Intensity-modulated radiation therapy (IMRT) as viable carotid-sparing techniques via reductions to the mean and max...

Late vascular complications after cranial radiotherapy: A report of two illustrative cases
We present two cases of late neurological complications after CRT and briefly discuss its diagnosis and their shared pathophysiological aspects. The first case is a patient with cognitive impairment associated to mineralizing microangiopathy ten years after CRT for nasopharyngeal carcinoma and the second one is a woman with Stroke-like Migraine Attacks after Radiation Therapy (SMART) syndrome two years after CRT for anaplastic meningioma. Nowadays, higher survival rates might cause an increase in appearance of late neurological complications after CTR. These reported cases show that late complications can mimic a wide vari...
