- ItemErdheim-Chester disease. Report of one case(SOC MEDICA SANTIAGO, 2011) Vega, Jorge; Cisternas, Marcela; Bergoeing, Michel; Espinosa, Roberto; Zapico, Alvaro; Chadid, Pedro; Santamarina, MarioWe report a 76-year-old male who was admitted due to progressive congestive heart failure lasting several months. An echocardiogram showed a large pericardial effusion with early signs of pericardial tamponade and an irregular surface suggestive of cancer infiltration. The patient was operated, creating a pericardial window and draining 1,200 ml of a brownish yellow fluid with abundant cellularity. Pericardial biopsy showed infiltration by CD68 (+), CD1a (-) and S100 (-) cells. Twenty-eight months earlier, due to fatigue, dyspnea, and a non-specific inflammatory process, an enhanced-contrast-scan showed that aorta was coated with a hypodense tissue that began near the aortic valve and extended until the inferior mesenteric artery, with stenosis of the left subclavian, celiac axis, renal and upper mesenteric arteries. An angioplasty and stent placing was carried out in the last two arteries. Both kidneys had the appearance of "hairy kidneys". A bone scan showed increased uptake in femurs and tibiae and X-ray examination showed osteosclerosis in metaphysis and diaphysis. The diagnosis of Erdheim-Chester disease (non-Langerhans-cell histiocytosis) was made and the patient was treated with steroids and methotrexate. (Rev Med Chile 2011; 139: 1054-1059).
- ItemPelvic intravenous leiomyomatosis with intracardiac extension. Report of two cases(SOC MEDICA SANTIAGO, 2012) Mertens, Renato; Valdes, Francisco; Munoz, Cecilia; Irarrazaval, Manuel; Branes, Jorge; Riquelme, Carlos; Marine, Leopoldo; Bergoeing, Michel; Kraemer, AlbrechtIntravenous leiomyomatosis with extension into the heart is an infrequent entity described in 1907. Its clinical presentation is non-specific, although cardiac symptoms predominate. Diagnosis is based on clinical findings and appropriate imaging. We report two females, aged 35 and 51 years. One of them presented with a pelvic mass and dyspnea, the other patient had severe cardiac failure on admission. Computed axial tomography scan allowed an accurate preoperative diagnosis on both patients. Successful one stage resection of the tumor was performed under cardiopulmonary bypass. Both patients are asymptomatic on follow up at 6 months and 25 years. (Rev Med Chile 2012; 140: 906-909).
- ItemVentana Fenestrated Stent-Graft System for Endovascular Repair of Juxtarenal Aortic Aneurysms(ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2012) Mertens, Renato; Bergoeing, Michel; Marine, Leopoldo; Valdes, Francisco; Kraemer, Albrecht; Vergara, JeanettePurpose: To describe the initial use of an off-the-shelf fenestrated stent-graft system for endovascular repair of juxtarenal abdominal aortic aneurysms.
