The role of cardiopulmonary bypass in the management of retrohepatic vena cava injury - A case report and review of the literature
No full textInjuries to the retrohepatic vena cava are extremely rare and are associated with an operative mortality of up to 50% even in high volume trauma centres. We present a patient with such an injury who underwent successful repair using cardiopulmonary bypass and deep hypothermic circulatory arrest.
A 23 year old male was transferred to our unit following laparotomy with packing of the abdomen after uncontrolled haemorrhage from the retrohepatic vena cava was experienced. The patient was placed on full cardiopulmonary bypass and cooled to 20 °C before clamping of the supracoeliac aorta and inferior vena cava. This facilitated exposure of the retrohepatic cava and allowed successful primary repair of a 5 cm laceration.
Other techniques to allow repair of these injuries, such as atriocaval shunts and total vascular exclusion of the liver, are associated with a high mortality. We believe the technique described in this case report is an alternative strategy that can be used successfully to manage life threatening from the retrohepatic vena cava

Estudo experimental do desempenho de um novo filtro de veia cava inferior
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Mecânica, Florianópolis, 2012Filtros de veia cava (FVC) são dispositivos médicos implantáveis utilizados na prevenção do tromboembolismo pulmonar (TEP). Este evento é uma desordem potencialmente fatal que ocorre em consequência do desprendimento e migração de um ou mais coágulos sanguíneos (trombos) formados no sistema venoso quando estes obstruem artérias pulmonares. Os filtros de veia cava inferior são empregados em cirurgias minimamente invasivas, ou seja, o filtro é alojado em um cateter que é conduzido por um vaso sanguíneo até a porção inferior da veia cava. O dispositivo consiste em uma estrutura cônica de hastes metálicas que se fixa na parede da veia através de sua base e tem a função de capturar coágulos sanguíneos e evitar sua chegada aos vasos pulmonares. O estudo apresentado neste trabalho é parte do processo de desenvolvimento de um novo filtro de veia cava criado pela empresa Biokyra Pesquisa e Desenvolvimento, onde foram conduzidos experimentos in vitro dos protótipos desenvolvidos. Os testes permitiram a avaliação de quatro fatores fisiológicos simulados: diâmetro da veia cava, vazão sanguínea e diâmetro e comprimento dos coágulos, através de testes de eficiência de captura e medição da pressão diferencial. A eficiência de captura é definida como a razão entre os coágulos inseridos no sistema circulatório simulado e os coágulos capturados pelo filtro e a pressão diferencial é a medida do aumento da pressão hidrostática referente à captura de coágulos pelos filtros de veia cava. Os resultados mostraram forte influência do comprimento dos trombos na eficiência de captura e considerável variação entre os diferentes filtros testados. As distintas geometrias dos filtros influenciaram os resultados de eficiência o que foi sistematicamente confirmado com testes dos variados parâmetros construtivos dos protótipos. Os experimentos permitiram a comparação entre filtros de veia cava comerciais e qualificaram os protótipos desenvolvidos para as etapas seguintes da validação dos dispositivos.Abstract : Vena cava filters (VCF) are implantable medical devices used in the prevention of the pulmonary thromboembolism (PE). This kind of event is a potentially deadly disorder which occurs in consequence of the dislodgement and migration of one or more blood clots (thrombi) formed in the deep venous system, when the clots obstruct pulmonary arteries. Inferior vena cava filters are employed in minimally invasive intervention, where the filter is housed in a catheter which is conducted through a blood vessel until the inferior portion of the vena cava. The device consists of a conical structure of metal rods fixed on the wall of the vein through its base and serves to capture blood clots preventing them of reaching the pulmonary vessels. The study presented in this paper is part of the product development process of a new vena cava filter designed by Biokyra Research and Development, where experiments were conducted for the in vitro evaluation of the developed prototypes. The test allowed evaluation of four simulated physiological factors: diameter of the vena cava, blood flow and the diameter and length of the clots by testing clot trapping efficacy and differential pressure measurement. The clot trapping efficacy is defined as the ratio of the inserted clots in the circulatory system and the simulated clot captured by the filter and the differential pressure is a measure of the increase in hydrostatic pressure caused by the clot capture in the vena cava filters. The results showed a strong influence of the length of thrombi in the clot trapping efficacy and considerable variation between the tested filters. The different geometries of the filters affected the results that were systematically confirmed with tests of various construction parameters of the prototypes. The experiments allowed comparison between vena cava filters and commercial prototypes and qualified the filters for the next stages validation tests

Emerging treatment options for acute bacterial skin and skin structure infections: focus on intravenous delafloxacin
No full textElda Righi, Alessia Carnelutti, Antonio Vena, Matteo Bassetti Infectious Diseases Division, Santa Maria della Misericordia University Hospital, Udine, Italy Abstract: The increase in hospitalization due to acute bacterial skin and skin structure infections (ABSSSI) caused by resistant pathogens supports the need for new treatment options. Antimicrobial options for ABSSSI that provide broad-spectrum coverage, including gram-negative pathogens and multidrug-resistant gram-positive bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), are limited. Delafloxacin is a novel fluoroquinolone available as intravenous and oral formulations and is characterized by an increased efficacy in acidic environments and activity on bacterial biofilm. Delafloxacin displays enhanced in vitro activity against MRSA, and enterococci, while maintaining efficacy against gram-negative pathogens and anaerobes. Delafloxacin has been studied for the treatment of ABSSSI and respiratory infections. Phase III studies have demonstrated noninferiority of delafloxacin compared to vancomycin, linezolid, tigecycline, and the combination of vancomycin plus aztreonam in the treatment of ABSSSI. Due to its favorable pharmacokinetic characteristics, the wide spectrum of action, and the potential for sequential therapy, delafloxacin represents a promising option in the empirical and targeted treatment of ABSSSI, both in hospital- and in community-based care. Keywords: bacterial skin and skin structure infections, multidrug-resistant bacteria, methicillin-resistant Staphylococcus aureus, delafloxaci

Blastomycosis granuloma involving the cranial vena cava associated with chylothorax and cranial vena caval syndrome in a dog
No full textA four-year-old, sexually intact, male dachshund was diagnosed with pulmonary blastomycosis. Itraconazole was administered for 60 days, and the dog was considered to be disease-free at three- and 12-month reevaluations. Two years following discontinuation of itraconazole, the dog developed a granuloma of the cranial vena cava resulting in chylothorax and cranial vena caval obstruction. To the authors' knowledge, this is the first case of a blastomycotic granuloma involving the vena cava reported in the dog. Blastomycosis should be considered as a differential diagnosis for both chylothorax and cranial vena caval syndrome in the dog
Fungal endocarditis in a premature infant complicated by a right atrial mycetoma and inferior vena cava thrombosis
No full textThe incidence of fungal endocarditis in premature infants is on the rise,
reported in the last decade secondary to use of central venous lines, the
frequent use of broad spectrum antibiotics and neonatal surgical
interventions. Central line related thrombosis is a significant risk factor for
persistent fungemia and end organ complications including endocarditis. This article presents a fatal case of progressive thrombosis of the inferior vena cava and
right atrial mycetoma in a premature infant with candidemia who underwent
ileostomy for bowel perforation. Renal failure occurred secondary to inferior
vena cava thrombosis and right atrial mycetoma, both of which had a potential
for hemodynamic compromise and embolism.peer-reviewe

Challenges and Solution of Invasive Aspergillosis in Non-neutropenic Patients: A Review
No full textInvasive aspergillosis (IA) is a serious opportunistic infection, which has increasingly been recognized as an emerging disease of non-neutropenic patients. In this group of patients, the diagnosis of IA can be challenging owing to the lack of specificity of symptoms, the difficulty in discriminating colonization from infection, and the lower sensitivity of microbiological and radiological tests compared with immunocompromised patients. The aim of this article is to present to clinicians a critical review on the management of IA in non-neutropenic patients
