Atualização do diagnóstico e tratamento do tromboembolismo pulmo / Update on diagnosis and treatment of pulmonary thromboembolism

A embolia pulmonar e a trombose venosa profunda são doenças com mesma base fisiopatogênica, denominada tromboembolismo venoso. Em 90% dos casos, os trombos originam-se no sistema da veia cava inferior, especialmente acima dos joelhos e pelve, alojando-se em ramos principais e segmentares dos pulmões, geralmentenos lobos inferiores. Nos Estados Unidos, é a terceira causa de óbito cardiovascular (seguida do infarto do miocárdio e acidente vascular cerebral isquêmico), com incidência anual estimada de 500.000 casos e 100.000 óbitos. A mortalidade hospitalar varia de 1% a 30%, dependendo das repercussões hemodinâmicas e da condição clínica do paciente. O diagnóstico e tratamento precoce reduzem a mortalidade hospitalar (disfunção e falência do ventrículo direito/hipoxemia) bem como suas principais complicações tardias: hipertensão pulmonar crônica, síndrome pós-trombótica, flegmasia alba dolens e cerulea dolens. O prognóstico poderá ser modificado adotando-se medidas preventivas, identificação e tratamento em tempo hábil, além da anticoagulação oral por período adequado...

Pulmonary embolism and deep vein thrombosis are diseases with same physiopathogenic base, called venous thromboembolism. In 90% of cases, thrombi originate in the inferior vena cava system, especially above the knees and pelvis, lodging in the main and segmental branches of the lungs, usually in the lower lobes. In the United States, it is the third leading cause of cardiovascular death (followed by myocardial infarction and ischemic stroke), with estimated annual incidence of 500,000 cases and 100,000 deaths. The hospital mortality rate ranges from 1% to 30%, depending on the hemodynamic effects and clinical condition of the patient. Early diagnosis and treatment reduce hospital mortality (dysfunction and failure of the right ventricle/hypoxemia) and its main late complications: chronic pulmonary hypertension, post-thrombotic syndrome, phlegmasia alba dolens and cerulea dolens. The prognosis may be modified by adopting preventive measures, identification and treatment in a timely manner, as well as oral anticoagulation for an adequate period...

Improving Indicators in a Brazilian Hospital Through Quality-Improvement Programs Based on STS Database Reports

ABSTRACT OBJECTIVE: To report the initial changes after quality-improvement programs based on STS-database in a Brazilian hospital. METHODS: Since 2011 a Brazilian hospital has joined STS-Database and in 2012 multifaceted actions based on STS reports were implemented aiming reductions in the time of mechanical ventilation and in the intensive care stay and also improvements in evidence-based perioperative therapies among patients who underwent coronary artery bypass graft surgeries. RESULTS: All the 947 patients submitted to coronary artery bypass graft surgeries from July 2011 to June 2014 were analyzed and there was an improvement in all the three target endpoints after the implementation of the quality-improvement program but the reduction in time on mechanical ventilation was not statistically significant after adjusting for prognostic characteristics. CONCLUSION: The initial experience with STS registry in a Brazilian hospital was associated with improvement in most of targeted quality-indicators.
