Angina mesentérica: causa infrecuente de dolor crónico en paciente en hemodiálisis / Mesenteric angina as a cause of abdominal pain in a patient in chronic hemodialysis: report of one case

We report a 73 years old male undergoing chronic hemodialysis with a history of seven years of abdominal pain and weight loss. A mesenteric angiography disclosed a critical stenosis of the celiac artery and a partial stenosis of the superior mesenteric artery. Other causes of abdominal pain were excluded. The patient was subjected to a successful angioplasty with stent placement that resulted in a complete relief of the pain

Edema pulmonar relámpago, flash pulmonary edema: cuando el riñón descompensa al corazón / Flash pulmonary edema, report of 2 cases

Flash pulmonary edema is a paroxismal pulmonary edema associated to a hypertensive crisis, that subsides in hours with the usual therapeutic measures. It occurs in patients with renal artery stenosis. We report two male patients aged 71 and 74 years old, presenting with acute dyspnea and high blood pressure. Diffuse rales were auscultated and arterial blood pressure was high in both. Dyspnea subsided in few hours with diuretics and oxygen. In both, a critical renal arterial stenosis was found and an angioplasty with stent placement was performed. After 5 and 6 months of follow up, the patients remain asymptomatic

Hipertensión renovascular y soplo abdominal en un caso: ¿ha modificado la tecnología su interpretación? / Renovascular hipertension and abdominal bruit: diagnostic implications of modern technological assessments: report of one case

A lateral abdominal bruit is considered an important finding for the detection of renovascular hypertension. However, the precision and accuracy of new techniques such as angiography, Doppler ultrasound and studies with radioisotopes have changed its value and clinical interpretation. We report a 75 years old woman with a bilateral renal artery stenosis in whom a bruit was heard over the artery that did not contribute to the genesis of hypertension and the significant arterial stenosis causing hypertension was silent. This particular situation could lead to erroneous clinical decisions

Angioplastia coronaria: estado actual y perspectivas / Coronary angioplasty: update state and perspectives

Since the first attempts to re-canalize peripherical arteries through rigid dilator (Dotter & Indkins) and specially since Andrea Gruentzig began with the coronary ballon angioplasty this technique has gone through and spectacular growth process, not just in how many times it is been used, but also in its consequential technological development. New devices had been incorporaded, like the directional aterectomy, coronary extraction aterectomy, rotablator, aterectomy through laser, intracoronary extraction prohesis, ultrasound and intracoronary angioscopy. The main indications and actual controversies concerning the coronary balloon angioplasty are discussed. Finally, a preliminary inform from our case studeis since september, 1991 through march 1993, is presented

Cirugía en paciente cardíaco: evaluación preoperatoria / Surgery in cardiac patient: preoperative approach of the risk

La evaluación preoperatoria de los pacientes cardíacos sometidos a cirugía general no siempre es fácil. Se analizan suscintamente las clasificaciones más utilizadas para estimar el riesgo de morbimortalidad operatoria, los principales indicadores clínicos preoperatorios y el manejo perioperatorio para cada una de las patologías cardiovasculares más frecuentes

Cirugía en paciente cardíaco: complicaciones postoperatorias / Surgery in cardiac patient: postoperative complications

La mayor proporción de las complicaciones cardíacas postoperatorias ocurre en los primeros 3 días despúes de la cirugía. El clínico debe estar atento a su desarrollo y utilizar todas las medidas para prevenirlas. Se analizan las principales complicaciones cardiovasculares postoperatorias y su manejo habitual
