A 5-year-old boy was diagnosed to have supravalvular aortic stenosis (SVAS). On evaluation of CT angiogram, there was associated bovine aortic arch (BAA). Association of BAA with SVAS has not been previously reported in literature, and to best of our knowledge, this is the first case report of SVAS with BAA. Recent studies show BAA as a marker for aortopathy. SVAS is also an arteriopathy. In light of this, SVAS can also possibly be a manifestation of aortopathy associated with BAA.

Computed tomography pulmonary angiogram (CTPA) provides a volumetric assessment of clot burden in acute pulmonary embolism (PE). However, it is unclear if clot burden is associated with right-sided heart strain (RHS) or adverse clinical events (ACE). We prospectively enrolled Emergency Department patients with PE (in CTPA) from 2008 to 2011. We assigned 1 to 9 points as clot burden score, based on whether emboli were saddle, central, lobar, segmental, and subsegmental. We evaluated a novel score (the "CT-PASS") based on the sum (in millimeters) of the largest filling defects in the right and left pulmonary vasculature...

PURPOSE: Optimizing the utilization of CT pulmonary angiogram (CTPA) for the diagnosis and workup of acute chest pain can provide an opportunity to reduce unnecessary radiation and health care system expense. METHODS: An attempt to improve CTPA utilization began by measuring overall department and clinician-specific utilization. This was bolstered by retrospectively evaluating patient charts for pulmonary embolism scoring criteria and D-dimer utilization so as to better understand gaps in diagnostic workup...

OBJECTIVE A common approach to lesions of the pineal region is along the midline below the torcula. However, reports of how shifting the approach off midline affects the surgical exposure and relationships between the tributaries of the vein of Galen are limited. The purpose of this study is to examine the microsurgical and endoscopic anatomy of the pineal region as seen through the supracerebellar infratentorial approaches, including midline, paramedian, lateral, and far-lateral routes. METHODS The quadrigeminal cisterns of 8 formalin-fixed adult cadaveric heads were dissected and examined with the aid of a surgical microscope and straight endoscope...

BACKGROUND: Transorbital intracranial penetrating trauma (TIPT) with a retained intracranial foreign body is a rare event lacking a widely-accepted diagnostic and therapeutic algorithm. Intraoperative catheter angiography (IOA) has been advocated by some authorities to rule out cerebrovascular injury prior and/or subsequent to removal of the object, but no standard of care currently exists. CASE DESCRIPTION: A 19-year-old male was involved in a construction site accident whereby a framing nail penetrated the left globe, traversed the lateral bony orbit, and terminated in the mid-temporal lobe...

Anterior tibial pseudoaneurysm is a rare complication after interlocking screw insertion in tibial nailing. We present the case of a 28-year-old male patient with this complication with a 6-week delay after tibial nailing of a right tibial fracture type 42-A1 of the Association for the Study of Internal Fixation (AO/ASIF) classification. On presentation to our emergency department, the patient's complaints were solemnly intermittent pain and occasional swelling of his proximal lower leg. Deep vein thrombosis, compartment syndrome, and implant dislocation were ruled out, and the patient was discharged after his symptoms improved without further intervention...

Intravascular ultrasound (IVUS) can provide valuable information regarding endoluminal morphology. We present the first description of IVUS-guided intracranial and extracranial carotid artery stent placement for arterial dissection. A 41-year-old female with a sudden-onset headache and blurred vision underwent a computed tomography (CT) angiogram imaging that revealed bilateral carotid artery dissections (BCAD) and a left vertebral artery dissection (VAD). Endovascular treatment (EVT) of a long segment right carotid artery dissection (CAD) was performed employing two Carotid WALLSTENT™ Monorails™ (8 x 36 mm, 10 x 31 mm) (Boston Scientific, Marlborough, MA)...

Pheochromocytoma is a rare adrenal gland tumour, usually alerting the physician by causing hypertensive tachycardic attacks. Patients with pheochromocytoma can rarely present with clinical signs similar to acute coronary syndrome. QT interval prolongation and ST segment changes due to pheochromocytoma have also been reported in the literature in a few case reports. We report a patient who had been admitted to the emergency department with chest pain, ischaemic ECG changes and marked QT prolongation. Despite a normal coronary angiogram, we observed that the QT interval and ST segment morphologies had changed during the hospitalisation period...

A 48-year-old woman with 40 years of intermittent squeezing chest pain presented with worsening symptoms. Results of an ambulatory electrocardiogram, echocardiogram, and exercise treadmill were unremarkable. Persistent symptoms prompted a computed tomography coronary angiogram (CTCA) that revealed mid-left anterior descending artery myocardial bridging (MB) that was not physiologically significant by exercise single-photon emission CT. Conservative treatment was pursued. Anatomic MB is prevalent in a large proportion of the general population and are increasingly identified by CTCA...

The majority of head and neck cancers arise from the oral cavity and oropharynx. Many of these lesions will be amenable to surgical resection using transoral approaches including transoral robotic surgery (TORS). To develop and control TORS tools, precise dimensions of the oral cavity and pharynx are desirable. CT angiograms of 76 patients were analyzed. For the oral cavity, only the maximum length and width were measured, while for the pharynx, the width, length, and areas of the airway were all measured and the volume calculated...

A 55-year-old man was working in a trench when the wall collapsed in on him, pinning him to the wall. On arrival in the emergency department the patient began reporting of right-sided headache. Neurological examination revealed left-sided reduced sensation with weakness. Whole-body CT scan showed right-sided flail chest and bilateral haemothorax as well as loss of flow and thinning of the distal right internal carotid artery (ICA) and loss of grey white matter differentiation in keeping with traumatic ICA dissection with a right middle cerebral artery (MCA) infarct...

ALCAPA syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease but lethal with clinical expression from myocardial infarction, congestive heart failure to death during early infancy and unusual survival to adulthood. We report a 73-year-old woman with ALCAPA who presented with exertional dyspnea (NYHA functional class II) over past 2 years. Physical examination revealed soft S, long mid diastolic rumbling murmur and apical pan-systolic murmur. Electrocardiography displayed biatrial enlargement and poor R progression and normal sinus rhythm...

INTRODUCTION: Developmental venous anomalies (DVAs) are cited as the most common cerebral vascular malformations. Still, intracerebral hematomas are rarely thought to be caused by DVAs. In this report, the authors present a unique case of a DVA that hemorrhaged spontaneously, rather than hemorrhaging into a venous infarction following DVA thrombosis as has been more commonly reported. CLINICAL PRESENTATION: A 22-year-old previously healthy male presented to the emergency department with a severe headache, confusion, and progressive hemiparesis...

BACKGROUND: Computed tomography Angiogram (CTA) is frequently utilized to detect vascular injuries even without exam findings indicating a vascular injury. We had the following hypotheses: 1) a CTA for lower extremity fractures with no clinical signs of a vascular injury is not indicated. 2) fracture location and pattern would correlate with the risk of a vascular injury. METHODS: A retrospective review was conducted on patients who had an acute lower extremity fracture(s) and a CTA...

The median arcuate ligament syndrome is a rare disorder characterised by postprandial intestinal angina caused by compression of the coeliac artery by the median arcuate ligament. To date, the diagnosis and treatment of median arcuate ligament syndrome has remained controversial. To our knowledge, this is the first reported case of coeliac artery compression demonstrated on the four-dimensional wide-area detector CT angiogram.
