Short posterior ciliary arteries (sPCA) provide the major blood supply to the optic nerve head. Emerging evidence has linked structural and functional anomalies of sPCA to the pathogenesis of several ocular disorders that cause varying degrees of visual loss, particularly anterior ischaemic optic neuropathy and glaucoma. Although the functional relevance of this vascular bed is well-recognized, the proteome of sPCA remains uncharacterized. Since the porcine ocular system closely resembles that of the human's and is increasingly employed in translational ophthalmic research, this study characterized the proteome of porcine sPCA employing the mass spectrometry-based proteomics strategy...

Low-flow venous malformations are congenital lesions and they are the third most common vascular anomaly in the head and neck. In this paper, the third in a series of three educational reviews, we discuss current trends in their management, and include a summary of common sclerosant agents used in their control.

OBJECTIVE: Disc edge veins of Kraupa are a rare anomaly of the retinal venous system in which the main trunk of the retinal vein disappeared into the margin of the optic disc instead of its centre. METHODS: A 40-year-old woman was detected to have an anomaly in her left optic disc in a routine eye examination. The eyes had an anomaly of the retinal venous system in which all branches of the retinal vein joined in a common trunk that entered the disc margin inferonasally...

INTRODUCTION: Giant cavernous malformation (GCM) in children is a rare vascular anomaly, and its natural history is unclear. Despite their giant size, intraparenchymal GCMs are low-flow vascular malformations. Herein, we report a case of hyper-vascular intraparenchymal GCM with an AV shunt in a child. CASE: A 3-year-old boy had had an enlarged head since infancy. Magnetic resonance (MR) images on admission showed a strikingly enhanced mass lesion, 6 cm in size...

AIM: To examine the prevalence and detailed radiological findings of internal anomalies in thalidomide embryopathy (TE). MATERIALS AND METHODS: Whole-body image screening for internal anomalies using unenhanced whole-body computed tomography (CT) and head magnetic resonance imaging (MRI) was performed in 22 patients (13 women and nine men; mean age, 49 years; range, 47-51 years) with TE. RESULTS: Among the 22 patients with TE, internal anomalies were detected in 19 (86...

AIM: To provide appropriate treatment, it is crucial to share the clinical status of pancreas head cancer among multidisciplinary treatment members. METHODS: A retrospective analysis of the medical records of 113 patients who underwent surgery for pancreas head cancer from January 2008 to December 2012 was performed. We developed preoperative defining system of pancreatic head cancer by describing "resectability - tumor location - vascular relationship - adjacent organ involvement - preoperative CA19-9 (initial bilirubin level) - vascular anomaly"...

PURPOSE: Unusual entrance of the vertebral artery into the cervical transverse foramen (UE-V2S) is a relatively common clinical anomaly. Because spinal surgeons should understand the anatomical characteristics and clinical implications of this condition, we aimed to provide a description based on a very large number of UE-V2S anomaly cases. METHODS: We retrospectively analyzed 2207 three-dimensional head-and-neck computed tomographic angiograms (CTAs) that did not have specific vascular abnormalities...

Cranio-vertebral junction is a pivot which holds the globe of the head. Bony anomalies at this point are particularly significant because they lodge the spinal cord and lower part of the brain stem. Clinically fusion of the atlas with the lower part of the occiput is known as Atlanto-occipital assimilation or atlas occipitalization, which can be either partial or complete depending upon the extent of fusion. It can present as totally asymptomatic accidental finding or can be a cause behind major neuro-vascular compression...

OBJECTIVE: To study the arterial spin-labeled (ASL) imaging features of vascular anomalies in the head and neck. MATERIALS AND METHODS: The presence or absence of ASL signal was evaluated for each vascular anomaly, and a comparison with conventional magnetic resonance (MR) sequences was performed. RESULTS: Twenty-five children were identified with vascular anomalies. All proliferating infantile hemangiomas demonstrated hyperintense ASL signal...

BACKGROUND: Free muscle transfer is an important in dynamic facial reanimation; however, suitable donor vessels in this population can be inadequate. In this case series, the submental vessels were used as donors to free gracilis muscle in vessel-depleted patients. METHODS: Five patients underwent free gracilis muscle transfer for smile reanimation, 2 with a prior failed free gracilis transfer, 2 with vascular anomalies, and 1 with previous distal ligation of the facial vessels...

To provide an overview of anomalies of the temporal bone in CHARGE syndrome relevant to cochlear implantation (CI), anatomical structures of the temporal bone and the respective genotypes were analysed. In this retrospective study, 42 CTs of the temporal bone of 42 patients with CHARGE syndrome were reviewed in consensus by two head-and-neck radiologists and two otological surgeons. Anatomical structures of the temporal bone were evaluated and correlated with genetic data. Abnormalities that might affect CI surgery were seen, such as a vascular structure, a petrosquamosal sinus (13 %), an underdeveloped mastoid (8 %) and an aberrant course of the facial nerve crossing the round window (9 %) and/or the promontory (18 %)...

We report a case of repeated cerebral hemorrhage associated with administration of rivaroxaban and apixaban. A 74-year-old man had undergone catheter ablation for non-valvular paroxysmal atrial fibrillation in 2 years prior. Warfarin treatment was continued after successful catheter ablation, and was then changed to rivaroxaban in 1 year prior. Three months later, he developed subcortical cerebral hemorrhage in the right occipital lobe and pharmacotherapy was changed to apixaban. At the current presentation, he complained of headache and left visual field defect, and was admitted to our hospital...

OBJECTIVE Cavernous hemangiomas are benign congenital vascular abnormalities. Intracerebral cavernous hemangiomas have an appreciable risk of spontaneous hemorrhage. Little is known as to whether head trauma increases the risk of bleeding for these lesions. In this study, the authors present a case series of 3 patients with posttraumatic nonspontaneous hemorrhage of intracerebral cavernous malformations (CMs). For the first time, to the authors' knowledge, they propose that trauma might constitute a risk factor for acute hemorrhage in intracerebral cavernomas...

IMPORTANCE: The field of vascular anomalies presents diverse challenges in diagnosis and management. Although many lesions involve the head and neck, training in vascular anomalies is not universally included in otolaryngology residencies and pediatric otolaryngology (POTO) fellowships. OBJECTIVE: To explore the education in, exposure to, and comfort level of otolaryngology trainees with vascular anomalies. DESIGN, SETTING, AND PARTICIPANTS: A survey was distributed to 39 POTO fellows and 44 residents in postgraduate year 5 who matched into POTO fellowships from April 22 through June 16, 2014...

OBJECTIVE: To study the clinicopathologic features of pediatric vascular anomalies and application of ISSVA classification. METHODS: The clinical features, histopathologic findings and immunohistochemical results were analyzed in 117 cases of pediatric vascular anomalies encountered during the period from May 2014 to May 2015. RESULTS: A total of 117 cases of vascular anomalies were studied. The age of patients ranged from 18 hours after birth to 11 years (mean age =34 months and median age =27 months)...

The aim of the study is to telemedically assess the prevalence of simple optic nerve atrophy and retinal arteriolar anomalies in subjects who have had a minor stroke or TIA within 14 days, and to compare these results with an age-matched control group. By using a mobile examination unit, retinal photographs were taken with a 45° non-mydriatic colour fundus camera (KOWA NM-45, non-mydriatic-alpha) in patients who had suffered from a minor stroke or TIA within 14 days of the time of the examination. Retinal photographs were focused on the optic nerve head region...
