Abstract: The occurrence of spontaneous subarachnoid haemorrhage (SAH) in association with coarctation of thoracic aorta and absence of intracranial aneurysm is a rare association. In spontaneous SAH, the predominant cause is intracranial aneurysmal rupture. This report describes a case of a 40 year-old male who presented with SAH and was incidentally diagnosed to have coarctation of aorta (CoA) with intraspinal collaterals on further work up. This case demonstrates the importance of detailed evaluation of patients with spontaneous SAH on whom common aetiologies have been ruled out. 2012-01-01T00:00:00Z /library/oar/handle/123456789/4292 Title: Pacemaker-associated cyanosis in an adolescent : the answer hiding behind shadows Authors: Wittekind, S.G.; Salerno, Jack Christian; Rubio, Agustin E. Abstract: Lead thrombosis is a recognized complication of permanent transvenous pacemaker (PM) implantation. We present the interesting case of an adolescent with a dual-chamber PM presenting with fatigue and hypoxemia. Due to limitations of various imaging modalities, the diagnosis was difficult. She was eventually diagnosed with intracardiac PM lead thrombi obstructing tricuspid valve inflow. The pediatric literature on PM lead thrombosis is also briefly reviewed. 2012-01-01T00:00:00Z
