ABSTRACT

Amyloidosis consists of deposition of insoluble fibrillar proteins in tissues and, causing dysfunction. In association with other factors, the condition can contribute to emergence of complications, such as pseudoaneurysms at arterial puncture sites. Pseudoaneurysms are becoming an ever-more common complication, which underscores the importance of identifying risk factors, so that their incidence can be minimized...


A amiloidose consiste em um depósito de proteínas fibrilares insolúveis em tecidos e órgãos, causando disfunção nos mesmos, e pode contribuir, associada a outros fatores, para formação de complicações, como pseudoaneurisma em locais de punção arterial. O pseudoaneurisma consiste de uma complicação cada vez mais frequente e, por isso, a importância de se identificarem seus fatores de risco, para que, então, sua incidência possa ser minimizada...

ABSTRACT

A cardiopatia isquêmica está comumente associada a arritmias ventriculares malignas, sendo ocardiodesfibriladorimplantável indicado para pacientes selecionados. Essa população faz uso de agentesantiagregantes plaquetários como terapia única ou com duas medicações combinadas. Embora fundamentaispara o tratamento da coronariopatia, os antiagregantes plaquetários aumentam o risco de sangramento nessespacientes, em especial ao se tratar de intervenção cirúrgica. Os autores relatam o caso de paciente portador dedesfibrilador cardíaco implantável e cardiopatia isquêmica, que precisou suspender o uso de antiagregantesplaquetários em decorrência de indicação cirúrgica de troca da unidade geradora por desgaste de bateria. Apóssuspensão da dupla antiagregação, o paciente apresentou choque apropriado decorrente de fibrilação ventricularsecundária a trombose aguda intrastent.


Ischemic heart disease is commonly associated with malignant ventricular arrhythmias and theimplantable cardiac defibrillator is indicated for selected patients. This population uses single or dual antiplatelettherapy. Although they are essential for the treatment of coronary artery disease, anti-platelet agents increase therisk of bleeding in these patients, especially in surgical interventions. The authors report the case of a patient withimplantable cardiac defibrillator and ischemic heart disease, who had to discontinue the use of antiplatelet agentsdue to the indication for device replacement surgery. After discontinuation of dual antiplatelet therapy, the patienthad appropriate shock resulting from ventricular fibrillation secondary to acute in-stent thrombosis.

ABSTRACT

INTRODUCTION: The majority of cases of stenosis or occlusion of central veins are the result of central catheters, arteriovenous fistulas, neoplasms or traumas and these conditions can cause severe cases of venous hypertension or reduce the flow through fistulas. The objective of this study is to analyze the results of central venous angioplasties conducted at our hospital. METHODOLOGY: We conducted a retrospective and descriptive study to analyze the results of central venous angioplasties conducted from 2010 to 2012 at a university hospital run by the Universidade Estadual de Londrina, Brazil. We calculated primary and secondary success rates and analyzed whether or not stents were used and complications occurred during a 6-month follow-up period. RESULTS: A total of 25 central venous angioplasties were conducted. Twenty-four (96%) of these were because of catheter-related intimal hyperplasia and one was to treat the effects of compression by a tumor. Fifteen (60%) angioplasties were to correct stenosis and ten (40%) were because of occlusions, with a one-hundred percent success rate for all stenosis-related procedures. However, none of the cases of occlusion could be treated endovascularly. Patency during the 6-months follow-up period was 80% after reinterventions. CONCLUSIONS: Despite good results observed after primary interventions for stenoses, it must be accepted that all current treatment options for chronic occlusive venous disease will, sooner or later, lead to restenosis or occlusion. Venous occlusions constitute a challenge demanding the development of new techniques and new materials. Prevention is paramount, through avoidance of central catheterization and early creation of arteriovenous fistulas...


INTRODUÇÃO: A estenose ou a oclusão de veias centrais ocorre, na maioria das vezes, em consequência de catéteres centrais, fístulas arteriovenosas, neoplasias e traumas, podendo levar a quadros severos de hipertensão venosa e de redução do débito dessas fístulas. O presente trabalho tem como objetivo analisar os resultados obtidos nas angioplastias venosas centrais em nosso hospital. METODOLOGIA: Realizamos um estudo retrospectivo, descritivo, analisando os resultados obtidos nas angioplastias venosas centrais realizadas no Hospital Universitário da Universidade Estadual de Londrina durante os anos de 2010 a 2012. Verificamos as taxas de sucesso primário e secundário, a utilização ou não de stents e as complicações, analisadas durante um período de acompanhamento de seis meses. RESULTADOS: Foram realizadas 25 angioplastias venosas centrais, sendo 24 (96%) por hiperplasia intimal relacionada ao uso de catéteres e uma por compressão tumoral. Destas, 15 (60%) eram estenoses e dez (40%) eram oclusões, obtendo-se sucesso primário técnico em todos os procedimentos relacionados à estenose. Contudo, nenhum caso de oclusão pode ser tratado por via endovascular. No acompanhamento de seis meses, após reintervenções, observamos perviedade de 80%. CONCLUSÃO: Apesar dos bons resultados observados nas intervenções primárias sobre as estenoses, indiscutivelmente todas as opções atuais para o tratamento da doença venosa oclusiva crônica irão levar, precoce ou tardiamente, à reestenose ou à oclusão. As oclusões venosas constituem uma incitação para o desenvolvimento de novas técnicas e novos materiais. A prevenção assume papel preponderante, com redução da implantação de catéteres...

ABSTRACT

Os autores relatam um caso de estenose de artéria hepática transplantada tratada com angioplastia e stent, que evoluiu para trombose completa após 30 dias do procedimento. Realizada trombólise intra-arterial e angioplastia subintimal com sucesso. Controle angiotomográfico após 90 dias demonstra perviedade da artéria hepática.


The present study reports a case of hepatic artery stenosis treated by percutaneous transluminal angioplasty and stent. After 30 days, this artery occluded and the patient was submitted successfully to thrombolysis and subintimal percutaneous angioplasty. Ninety days after the procedure a computed tomography showed patency of hepatic artery.

ABSTRACT

Cardiac rehabilitation [CR] reduces cardiovascular mortality and improves cardiovascular and mental status of cardiac patients. Evaluation of the effects of CR in different groups according to sex, age and cause of disease would help the CR program to be special and individual and reduces the cost of treatment. The aim of this study was to evaluate the outcomes of CR in patients referring to CR program with different reasons. We studied 310 cardiac patients including 150 CABG, 44 PTCA and 110 persons with any other cause like Ml, angina, etc. without revascularization. All patients were subjected to a 24 sessions of CR including aerobic exercise, education and diet therapy. Exercise capacity, ejection fraction [EF], lipid profile and body mass index [BMl] were measured before and after the CR program. The data were analyzed using Chi-square, independent pair t-test and ANOVA. Results of this study showed that lipid profile, exercise capacity, EF and BMl were improved after CR in all groups. Changes of the variables were the same in all groups and the differences were not statistically significant. all the male and female patients attending CR program equally benefited from cr. we concluded that patients under medical treatment could improve their cardiovascular status before revascularization and sometimes postpone the intensive procedures
