Positive Association between Neutrophil-Lymphocyte Ratio and Presence of Panoramically Imaged Carotid Atheromas Among Men
Heightened levels of systemic inflammation documented by elevated neutrophil-lymphocyte ratios (NLRs) characterize robust atherosclerosis processes evidenced by carotid and coronary artery plaques on ultrasound and angiography with associated strokes and myocardial infarctions (MIs). Therefore, we sought to determine if calcified carotid artery plaques (CCAP) on panoramic images (PIs), known to herald future stroke and MI, are associated with elevated NLRs.

Arteriovenous Lesions of the Internal Auditory Canal
Conclusion: We report a novel case of an occult asymptomatic IAC arteriovenous lesion. Vascular anomalies confined to the IAC are rare. To date, there have been only four reports in the literature of IAC arteriovenous lesions and our case is the first to present asymptomatically. A high index of suspicion and dedicated imaging is required to identify and accurately diagnose these lesions to guide appropriate counseling and potential intervention.

Blunt cerebrovascular injury following craniomaxillofacial fractures: A systematic review
ConclusionBlunt cerebrovascular injury is a rare but devastating complication of blunt trauma. The recommended screening modality is CTA, and the most common treatment is antiplatelet/anticoagulant medication. Mandibular and LeFort fractures were the most common isolated CMF injury associated with BCVI, highlighting the need for prospective trials to expand current screening criteria. Level of EvidenceN/A.

Internal carotid artery injury in endoscopic endonasal surgery: A systematic review
ConclusionsThe incidence of reported cases of ICA injury during EES remains low. Left‐sided injuries to the cavernous segment of the ICA occurred more frequently than injuries on the right. Level of EvidenceNA Laryngoscope, 2015

Delayed Carotid Dissection Following Lower Lip Revascularization in the Setting of Hyoid Fracture—A Case Report and Review of the Literature
This report describes the case of a 53-year-old woman who sustained a lower lip avulsion injury, a comminuted mandibular parasymphyseal fracture, and a hyoid bone fracture secondary to a bicycle accident. Trauma workup included computed tomographic angiography of the head and neck, which did not show vascular injury. Despite successful revascularization of the lower lip, on postoperative day 11 the patient developed a large internal carotid artery dissection and middle cerebral artery stroke.

Intraoperative stroke in the mandibular osteoradionecrosis: A case report
Publication date: January 2015 Source:Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology, Volume 27, Issue 1 Author(s): Ryo Sasaki , Chie Kagawa , Toshihiro Okamoto , Tomohiro Ando Although risk factors for perioperative stroke during head and neck surgery are known, the risk of perioperative stroke in osteoradionecrosis (ORN) patients is scarcely known. Sixty-seven-year-old male presented ORN in the mandible after 9 years docetaxel, cisplatin, and 5-fluorouracil (TPF) chemo, and 66Gy radiation therapies for the oropharynx cancer, which was diagnosed Marx's classification class II.

Posterior circulation ischemic stroke in childhood and neurofibromatosis type 2
We report the clinical and genetic findings and review the previous literature on vasculopathy reported in association with NF2, with a focus on the symptoms presenting at disease onset. For our case patient, an unpublished germline mutation resulting in frameshift (c.876_877insT) was identified on blood screening. We report our full multidisciplinary assessment with vascular angiography, volumetric MRI and audiometry. Vasculopathy is not currently included in the criteria traditionally used for diagnosis of NF2. We suggest that vascular stroke in childhood may be considered a presenting symptom for NF2.

Risks of radiation versus risks from injury: A clinical decision analysis for the management of penetrating palatal trauma in children
ConclusionsRoutine use of computed tomography with angiography for well‐appearing children with palatal trauma should be reconsidered, as the risk of radiation‐induced malignancy may outweigh the benefit of identifying the rare carotid injury. Level of Evidence2b. Laryngoscope, 2013

Use of the radial forearm artery for secondary embolization of an extensive life-threatening arteriovenous malformation of the mid-face and anterior skull base – A case report
Conclusion: In extensive vascular malformations of the head and neck, complete surgical removal is often impossible and associated with high risk of complications and mortality. Endovascular embolization is limited by the location of the AVM and can potentially cause stroke, ischaemia, necrosis, bleeding, blindness and adverse haemodynamic changes.
