Nicola Y Gan, Cheryl Zimmer, Wai-Ching Lam
BACKGROUND AND OBJECTIVE: To illustrate the features of a circumscribed choroidal hemangioma (CCH) using Annidis RHA multi-spectral imaging (MSI) technology (Annidis Corporation, Ottawa, Canada). This novel imaging technique uses non-overlapping, narrow-band LED light sources ranging from 520 nm to 940 nm to create a monochromatic series of en face fundus images and oxy/deoxyhemoglobin contrasted maps of the retina and choroid. PATIENTS AND METHODS: Annidis RHA MSI images were taken of a 67-year-old Chinese male with CCH...

INTRODUCTION: Endothelial dysfunction could contribute to the pathophysiology of angina pectoris (AP) in patients with normal coronary angiograms. Besides lipid-lowering effects, statins exert pleiotropic effects including improving endothelial function. MATERIAL AND METHODS: Our double-blind study included 58 patients with AP, noninvasively confirmed myocardial ischemia and a normal coronary angiogram. The effect of once-daily 20 mg atorvastatin (A) was compared with placebo (P) for 6 months...

A 55-year-old man presented with difficulty breathing, chest pain, and disturbance of consciousness, and was transferred to our hospital. Initial whole body CT revealed a diffuse subarachnoid hemorrhage(SAH)with severe pulmonary edema that was considered neurogenic in origin. He received controlled ventilation under sedation and conservative care for the SAH. One day after the onset of the SAH, his left pupil suddenly became dilated to 6mm, with no reaction to light. Head CT showed no new bleeding. Subsequent CT angiogram revealed a right internal carotid-posterior communicating artery aneurysm(IC-PC AN)with a posterior-lateral projection; however, no vessel abnormality was observed in the left anterior or posterior circulations...

Surgical resection of solid cerebellar hemangioblastomas can be challenging because of the profuse blood supply and tight space. We report two cases of solid cerebellar hemangioblastomas treated via surgical resection with the aid of preoperative endovascular embolization on the day of surgery. Case 1: A 36-year-old woman presented with a two-month history of headache and vomiting. Magnetic resonance imaging(MRI)revealed a right cerebellar solid mass, mild hydrocephalus, and apparent peritumoral edema. Angiogram showed a highly vascularized mass, three feeding arteries from the superior cerebellar artery(SCA), and a dilated vein draining into the confluence...

BACKGROUND: Tentorial dural arteriovenous fistulas(dAVFs)are a rare clinical entity accounting for less than 10% of all intracranial dAVFs. Because these lesions are characterized by high hemorrhagic risk, aggressive treatment should be considered. Although the number of reported cases treated with endovascular transarterial embolization(TAE)using glue has been increasing, little is known about the transvenous approach. Here, we report the case of a patient with a tentorial dAVF who was successfully treated with transvenous embolization(TVE)through venous drainage using a double catheterization technique...

We present a case of a 21-year-old man presenting with sharp left-sided chest pain. A CT pulmonary angiogram was negative, ECG was unremarkable and a mild troponin rise was observed. Myocarditis was suspected as the most likely diagnosis, particularly in view of the patient's previous diagnosis of myocarditis 3 years prior. A cardiac MRI was indicative of an acute mid-anterior myocardial infarction (MI) and an old inferior MI with an associated aneurysm. A subsequent angiogram revealed a subtotal occlusion in the second diagonal artery, likely precipitated by homozygous factor V Leiden...

A 45-year-old man with a raised body mass index presented with an acute history of right lower chest pain and increasing breathlessness. C reactive protein, D dimer and cardiac echocardiography were negative, with mild bibasal atelectasis the only positive reported finding from erect chest X-ray and CT pulmonary angiogram. He was discharged with antibiotics for a chest infection. He remained severely breathless and was referred to the sleep-related breathing disorders clinic. He described shoulder pain, daytime tiredness and sleeping upright due to a ââ'¬Ëœsuffocatingââ'¬â"¢ sensation...

Coronary chronic total occlusions (CTOs) are found in approximately 20% of angiograms. We sought to assess the variation in the management of patients with CTOs and to compare the clinical outcomes of CTO lesions with those of non-CTO lesions. We conducted a population-based cohort study and included all patients with stable angina who underwent cardiac catheterization from October 1, 2012, to June 30, 2013, in Ontario, Canada. The primary outcome was a composite of mortality and hospitalization for myocardial infarction...

BACKGROUND: The ascending pharyngeal artery (APA) may rarely arise from the common carotid artery bifurcation. We herein report an injury to the APA as an unusual complication of pre-dilation balloon inflation during carotid artery stenting (CAS) with flow reversal. CASE DESCRIPTION: A 73-year-old man presented with symptomatic severe left cervical internal carotid artery (ICA) stenosis. The left APA arose from the common carotid artery bifurcation. We performed CAS with flow reversal to decrease the risk of distal embolization...

BACKGROUND: Thrombocytosis and inflammation are vital elements in the pathogenesis of atherosclerosis. The platelet-to-lymphocyte ratio (PLR) is a novel biomarker that combines these parameters and has been shown to be associated with cardiovascular disease (CVD). This study aimed to determine whether PLR correlates with coronary artery disease (CAD) in high-risk patients, and if the relationship is affected by age. METHODS: Consecutive patients referred for coronary angiogram were evaluated (n=822)...

Myocardial infarction (MI) is an extremely common cause of chest pain. MI can be acute with ST elevation (STEMI) or non-STEMI (NSTEMI). Coronary artery spasm can be severe enough to cause occlusion of the coronary arteries particularly with an exaggerated response in regions of coronary atheroma and plaque ulceration. It is not uncommon for coronary spasm to be mistaken with acute thrombotic occlusion of the coronary artery. We describe a case of a 42-year old man with known cardiac risk factors presents with chest pain for few hours to a tertiary centre hospital...

Hashimoto's encephalopathy is a rare form of autoimmune encephalopathy. It is likely an underdiagnosed entity especially in the setting of focal neurological defects. We report a case of a 49-year-old man who presented with "strange behavior"of a day's duration. Examination was significant only for lethargy, poor attention span and agitation. Routine labs revealed leucocytosis. Head CT scan was unremarkable. Lumbar puncture showed high white blood cells with lymphocytosis and elevated protein level. The patient was empirically treated for meningitis without improvement...

PURPOSE: Early detection of blood vessel pathologies can be made through the evaluation of functional and structural abnormalities in the arteries, including the arterial distensibility measure. We propose a feasibility study on computing arterial distensibility automatically from monoplane 2D X-ray sequences for both small arteries (such as coronary arteries) and larger arteries (such as the aorta). METHODS: To compute the distensibility measure, three steps were developed: First, the segment of an artery is extracted using our graph-based segmentation method...

PURPOSE: Shared decision-making, when physicians and patients collaborate and agree on health care decisions, is a key tenant of patient-centered care. Choice of access site for neurovascular procedures is rarely a shared decision point between physicians and patients. We present our initial evaluation of patient preference for radial over femoral access for cerebrovascular procedures. MATERIALS AND METHODS: IRB approved single-center, prospective, and consecutive survey of all patients undergoing transradial access for cerebrovascular imaging and intervention...

We present the case of a 65-year-old male who presented with stable angina and dyspnea on exertion. His initial workup yielded a positive treadmill stress test for reversible apical ischemia, and transthoracic echocardiogram demonstrated impaired systolic function. Cardiac catheterization was then performed, revealing severe atherosclerotic disease including multiple coronary artery aneurysms. As a result, the patient was advised to and subsequently underwent a coronary artery bypass graft. This case highlights the presence of multiple coronary artery aneurysms and the ability to appreciate these pathologic findings on multiple imaging modalities, including coronary angiogram, transesophageal echocardiography, and direct visualization through the surgical field...

BACKGROUND: Patients with Moyamoya or other intracranial steno-occlusive disease are at risk for developing aneurysms associated with flow through collateral vessels. Because these lesions are rare, the optimal management remains unclear. Here, we describe two cases of microsurgical repair of ruptured collateral vessel aneurysms associated with middle cerebral artery (MCA) occlusion. CASE DESCRIPTION: The first patient was a 61-year-old male who presented with right frontal and intraventricular hemorrhage...
