Introduction: Central vein stenosis is a challenging problem faced by hemodialysis patients. Significant arm swelling, facial plethora, skin breakdown and loss of dialysis access are potential complications, which limit both the quality life expectancy these Amongst patients in Mombasa County, incidence subclavian catheter utilization common, leading to higher-than-expected symptomatic central ...

n engl j med 354;21 www.nejm.org may 25, 2006 2289 To the Editor: In their study of circumferential pulmonary-vein ablation in patients with chronic atrial fibrillation, Oral et al. (March 2 issue)1 do not mention evaluation or discuss the potential complication of pulmonary-vein stenosis. In their definition of ostial stenosis, they rely on the electroanatomical “tube depiction” method as a gu...

BACKGROUND AND PURPOSE Little is known about how commonly the internal jugular vein is compressed by extrinsic structures in the upper neck. The purpose of this paper was to identify the frequency and cause of external compression of the superior segment of the internal jugular vein. MATERIALS AND METHODS Retrospective review of CT angiograms of the neck was performed in 108 consecutive patie...

this article describes coronary artery bypass grafting by avlliath jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. the aim of coronary artery bypass grafting is to release pain, prevention of myocardial inf...

OBJECTIVES Retrospective analysis of five cases of coronary vein balloon angioplasty performed to allow insertion of left ventricular pacing leads. BACKGROUND Coronary vein stenoses or an insufficient vessel caliber can preclude transvenous placement of coronary vein leads. METHODS We compared our total patient population (n = 218), in whom we implanted coronary vein leads, to those five pa...

Critical congenital pulmonary stenosis with intact interventricular septum is a cyanotic and potentially lethal neonatal cardiac anomaly. Percutaneous transcatheter balloon valvuloplasty for critical often presents technical difficulties due to supra-systemic pressure in right ventricle. Using transjugular approach instead of the femoral vein helps dealing this issue. We describe successful use...

AIMS Pulmonary vein ablation offers the potential to cure patients with atrial fibrillation. In this study, we investigated the incidence of pulmonary vein stenosis after radiofrequency catheter ablation of refractory atrial fibrillation by systematic long-term follow-up. METHODS AND RESULTS Forty-seven patients with refractory and highly symptomatic atrial fibrillation underwent radiofrequen...

The purpose of this study was to evaluate the feasibility and accuracy of combined coronary and perfusion cardiovascular magnetic resonance (CMR) in the assessment of coronary artery stenosis. Thirty-five consecutive patients (27 men, eight women, age range 34-81 years), undergoing cardiac catheterization, were assessed with 3D coronary CMR and rest-stress perfusion CMR. Significant coronary st...

BACKGROUND Superior mesenteric vein stenosis as a consequence of mesenteric fibrosis, causing the development of small bowel varices, is an unrecognised association of Crohn's disease. CASE REPORTS Two cases of gastrointestinal bleeding occurring in patients with Crohn's disease, and a third case, presenting with pain and diarrhoea, are described. In all three patients, visceral angiography s...
