Prognostic value of computed tomographic pulmonary angiography and the pulmonary embolism severity index in patients with acute pulmonary embolism

Blood Coagulation & Fibrinolysis (2012)

Thiago Horta Soares Marcos de Bastos Bruna Vilaça de Carvalho Wanderval Moreira Cristiane Pena Cabral

Pulmonary embolism is a serious and potentially fatal disorder. Pulmonary embolism risk stratification may allow early hospital discharge and outpatient treatment for low-risk patients. Also, it may prevent death by early medical intervention in high-risk groups. We evaluated objectively confirmed pulmonary embolism in 126 patients by multidetector computed tomographic pulmonary angiography at a single center from January 2008 to January 2010. The Pulmonary Severity Embolism Index (PESI), the right ventricle (RV) to left ventricle (LV) diameter (RV/LV) ratio and the vascular obstruction index (VOI) were derived from data extracted from electronic hospital records and image database. A total of six out of 96 patients (6.3%) died during follow-up. There was an association between PESI and mortality (P-value < 0.001 χ2 test). PESI class I–II had a 100% negative predictive value for death in 90 days. No association was found between the RV/LV ratio, the VOI and mortality (P-value > 0.05 χ2 test). Also, no association was found between the RV/LV ratio and the VOI and PESI (P-value > 0.05 χ2 test). PESI is an accurate tool for pulmonary embolism prognostic stratification. It safely discriminates low-risk from high-risk patients regarding death outcome. We were unable to demonstrate an association between image scores and mortality.

Persistence of stapedial artery: a case report

Radiologia Brasileira (2013)

Bruna Vilaça de Carvalho Juliana Oggioni Gaiotti Renata Lopes Furletti Caldeira Diniz Marcelo Almeida Ribeiro Emília Guerra Pinto Coelho Motta

Persistent stapedial artery is a rare congenital anomaly that occurs by a failure in the involution of such artery. Most patients with persistent stapedial artery are asymptomatic. The imaging diagnosis is made principally by means of multidetector computed tomography. In the present case, persistent stapedial artery was an incidental computed tomography finding. The authors discuss the embryogenesis, computed tomography findings and the importance of an early diagnosis of such anomaly.

Typical and atypical presentations of paranasal sinus mucocele at computed tomography* Apresentações típicas e atípicas de mucocele dos seios paranasais na tomografia computadorizada

Bruna Vilaça de Carvalho Izabella de Campos Carvalho Lopes James de Brito Corrêa Mourão Ramos

Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of asinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinicalsymptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgeryis the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasalsinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings.Keywords: Paranasal sinuses; Mucocele; Presentation; Atypical.As mucoceles sao formacoes cisticas que podem afetar os seios paranasais. Ocorrem quando ha obstrucao na drena-gem de um seio, com resultante acumulo de secrecao. Os seios frontal e etmoidal sao os mais acometidos. A apresen-tacao clinica normalmente tem sintomas insidiosos que variam com a extensao da regiao acometida. O tratamento ecirurgico, sendo a cirurgia endoscopica o metodo de escolha na maioria dos casos. O objetivo do nosso estudo edescrever as principais caracteristicas das mucoceles dos seios paranasais, bem como demonstrar e ilustrar uma seriede apresentacoes atipicas, com enfase nos achados de imagem.Unitermos: Seios paranasais; Mucocele; Apresentacao; Atipica.AbstractResumo
