OBJECTIVE: Quantification of retinal vessel morphology has emerged as a marker of cardiovascular health. We examined retinal microvascular diameters in RA, particularly in regard with systemic inflammation, subclinical atherosclerosis and cardiovascular risk. METHODS: Retinal images from RA patients and controls were processed using computerized software, to obtain central retinal arteriolar (CRAE) and venular (CRVE) equivalent and arteriovenous ratio (AVR). Subclinical atherosclerosis was assessed with carotid intima-media thickness (cIMT), and 10-year risk of general cardiovascular disease was calculated...

BACKGROUND: The present study was designed to assess the underlying mechanism of decline in effort capacity seen with aging. METHODS: We analyzed 250 healthy senior patients (≥65 years) with an ejection fraction ≥60% who underwent a stress echocardiogram test. The seniors (aged 65-94) were divided into 3 equal age groups (groups 1, 2, and 3), and their echo characteristics at rest and peak exercise (measured and calculated) were compared. RESULTS: Diastolic function at rest declined significantly (E lateral, E septal, E/E', A) with age, while other rest parameters were similar...

This is a case report of a 60-year-old male admitted on suspicion of relapse of idiopathic transverse myelitis (TM), who after further diagnostic workup underwent successful closure of a dural arteriovenous fistula (DAVF). Magnetic resonance imaging in DAVF usually shows longitudinal TM, which, unlike DAVF, is also seen with the more common inflammatory or infectious causes usually showing inflammation in the cerebrospinal fluid. The natural history of DAVF is progressive. Since curable options exist, timely diagnosis is most important...

BACKGROUND: Transvenous (TV) embolization is ideal for endovascular treatment of intracranial dural arteriovenous fistulas (DAVF). However, it is not always feasible because of various factors, and transarterial (TA) embolization could then be tried. We aimed to determine the incidence of 'distally enlarged feeding artery phenomenon' and the major feeding artery in DAVF. In case TV approach is difficult and this phenomenon observed, we could use this vessel for transarterial intravenous (TAIV) embolization as an endovascular treatment modality for DAVF...

Over the past half-century since Lars Leksell first utilized radiation to address deep and difficult to treat lesions of the central nervous system (CNS), intracranial stereotactic radiosurgery (SRS) has become an increasingly valued tool in the hands of neurosurgeons and radiation oncologists. Following developments in medical imaging and radiation technology, radiosurgery has evolved from its first application in movement disorders to widespread use for a varied range of malignant and benign conditions. SRS remains a powerful, minimally invasive instrument that offers additional options for intervention to a diverse patient population...

PURPOSE: To investigate pulmonary venous anomaly as a cause of pulmonary arteriovenous malformation (PAVM) misdiagnosis. MATERIALS AND METHODS: We reviewed adult patients within a 7.5-year period with CT scans initially diagnosed with PAVM and subsequent conventional pulmonary angiograms. RESULTS: Pulmonary arteriography showed no PAVM on arterial phase for 10 out of 99 patients, comprising the misdiagnosed group. Four misdiagnosed patients had pulmonary venous anomalies and six had nodular lesions on CT...

OBJECTIVES: To systematically assess the difference between both procedures in terms of access maturation, patency and postoperative complications. BACKGROUND: An arteriovenous fistula (AVF) is the best modality for haemodialysis (HD) access. The end-to-side (ETS) technique has been suggested in the literature to produce superior results to the side-to-side approach; however, in the absence of a systematic review, this practice remains debatable. METHODS: Online search for randomised controlled trials (RCTs) and observational studies that compared the end-to-side versus the side-to-side anastomosis techniques in creating an upper limb AVF...

Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular malformation of the spinal cord, causing segmental lesions of the spinal cord due to venous ischemia. Functional outcomes of treatment in SDAVF patients are favorable, but the rate of improvement varies from 25 to 100%, which complicates prediction of the treatment outcome. AIM: the study aim was to identify a relationship between fistula localization and clinical manifestations and evaluate the effect of disease duration and severity of neurological impairments on immediate and long-term treatment outcomes, based on analysis of the literature and own data...

OBJECTIVE: This study reviewed our experience with proximal radial artery-based arteriovenous fistulas (PRA-AVFs) for hemodialysis vascular access, evaluating characteristics of the patients, functional patency, risk of steal syndrome, survival of the patient, and technical considerations. METHODS: We retrospectively analyzed our database of consecutive patients, identifying those individuals with a PRA-AVF created during a 12-year period. In addition to physical examination, all patients underwent ultrasound vessel mapping by the operating surgeon, identifying the PRA-AVF configuration and outflow target most likely to succeed...

BACKGROUND: Arteriovenous fistula (AVF), permanent catheter (PC), and vascular graft are three vascular access types used for hemodialysis procedure. Due to insufficient reliable information on the comparison between AVF and PC, this study was conducted to compare AVF and PC regarding dialysis adequacy. MATERIALS AND METHODS: This prospective study was carried out from March, 2013 to September, 2013. In this study, 76 hemodialysis patients were enrolled and assigned to two unequal groups of AVF and PC...

BACKGROUND: Indocyanine green (ICG) videoangiography can be used to delineate the locations of the cortical vessels just prior to dural opening, allowing safe and optimal dural opening. The present clinical series demonstrates the adjunct use of ICG videoangiography to optimize dural opening for the treatment of various cerebrovascular diseases. METHODS: A total of 45 patients underwent surgery for superficial temporal artery-middle cerebral artery bypass (40), arteriovenous malformation (2), and dural arteriovenous fistula (3) between January 2012 and December 2016...

Visual impairment can complicate cerebral venous thrombosis (CVT). Here, we describe the various pathophysiological mechanisms and treatments available. A retrospective chart review of all patients treated for CVT in a large quaternary teaching hospital was done, and cases with visual impairment due to CVT were identified. The various mechanisms causing visual impairment in CVT were (1) raised intracranial pressure (ICP) caused by venous thrombosis without venous infarcts resulting in a benign intracranial hypertension-like presentation of CVT, (2) venous infarcts involving the occipital cortex, (3) raised ICP following the development of a secondary dural arteriovenous (AV) fistula, and (4) arterial occipital infarcts due to posterior cerebral artery compression secondary to herniation in large venous infarcts...
