Diagnóstico y Tratamiento de Tromboembolismo Pulmonar Masivo Mediante Trombectomía Mecánica. Reporte de un caso / Diagnosis and Treatment of Massive Pulmonary Embolism by Means of Mechanical Thrombectomy. Case Report

El Tromboembolismo pulmonar puede considerarse una de las complicaciones más graves en Medic ina. Consiste en la obstrucción de una arteria pulmonar, usualmente secundaria a un trombo. Esta obstrucción condiciona una disminución de la perfusión sanguínea a los alveolos, lo que lleva a la disminución de la oxigenación sanguínea corporal. Entre los síntomas más comunes, podemos obs erv ar disnea, dolor torácico y los signos más comunes son la disminución de la saturación de ox igeno, la taquipnea y la taquicardia. Con las mejoras tecnológicas y las mejoras en la precisión diagnóstica, la tomografía computada se ha convertido en el estudio de elección es pecíficamente, la Angiotomografía de Tórax.

Pulmonary Thromboembolism can be considered one of Medicine's most severe complications. It cons ists in the obstruction of a pulmonary artery, usually caused by a thrombus. This obstruction caus es a reduction of blood flow to the alveoli which consequently diminishes blood oxygenation for the rest of the body. The most common symptoms seen are dyspnea, thoracic pain and the most common clinical signs are tachycardia, tachypnea and a reduction in blood saturation. With the adv ances in technology and the improvements in diagnostic precision, Computed Tomography has become today's gold standard, specifically Computed Angiotomography.

Intercomparison of oil spill prediction models for accidental blowout scenarios with and without subsea chemical dispersant injection.

We compare oil spill model predictions for a prototype subsea blowout with and without subsea injection of chemical dispersants in deep and shallow water, for high and low gas-oil ratio, and in weak to strong crossflows. Model results are compared for initial oil droplet size distribution, the nearfield plume, and the farfield Lagrangian particle tracking stage of hydrocarbon transport. For the conditions tested (a blowout with oil flow rate of 20,000 bbl/d, about 1/3 of the Deepwater Horizon), the models predict the volume median droplet diameter at the source to range from 0.3 to 6mm without dispersant and 0.01 to 0.8 mm with dispersant. This reduced droplet size owing to reduced interfacial tension results in a one to two order of magnitude increase in the downstream displacement of the initial oil surfacing zone and may lead to a significant fraction of the spilled oil not reaching the sea surface.
