ABSTRACT

El pseudoaneurisma se puede definir como un hematoma pulsátil repermeabilizado y encapsulado, en comunicación con la luz de un vaso dañado. Los pseudoaneurismas de las extremidades son los más frecuentes; entre ellos se destacan los iatrogénicos de la arteria femoral. Su incidencia es del 2 por ciento-8 por ciento cuando se realizan angioplastia/stent coronarios y del 0,2 por ciento-0,5 por ciento cuando únicamente se hace angiografía diagnóstica. Se presenta un paciente con diagnóstico de pseudoaneurisma femoral derecho posterior a un cateterismo cardíaco, con el objetivo de demostrar la importancia del diagnóstico temprano de las pseudaeurismas para el tratamiento quirúrgico oportuno y evitar complicaciones posteriores. Al mes del procedimiento, el paciente comenzó con aumento de volumen en la región inguinal derecha y a la auscultación se apreció un soplo a ese nivel. Se le realizó exérisis del pseudoaneurisma y reparación quirúrgica de la arteria femoral. En las consultas de evaluación posoperatoria se mostró una evolución clínica y radiológica satisfactoria. El diagnóstico rápido de estas entidades vasculares evita que se presenten complicaciones posteriores y aseguran una evolución rápida y satisfactoria de los pacientes que la padecen(AU)


Pseudoaneurysm can be defined as a repermeabilized and encapsulated pulsatile hematoma, in communication with the light of a damaged vessel. Pseudoaneurysms of the limbs are the most frequent; among them are the iatrogenic of the femoral artery. Its incidence is 2 percent -8 percent when coronary angioplasty/stent is performed and 0.2 percent-0.5 percent when only diagnostic angiography is performed. A patient with a diagnosis of right femoral pseudoaneurysm after cardiac catheterization is presented, with the aim of demonstrating the importance of early diagnosis of pseudoaneurysms for timely surgical treatment and avoiding subsequent complications. A month after the procedure, the patient began with an increase in volume in the right inguinal region and auscultation showed a murmur at that level. Pseudoaneurysm exeresis and surgical repair of the femoral artery were performed. In the postoperative evaluation consultations, a satisfactory clinical and radiological evolution was shown. The rapid diagnosis of these vascular entities prevents subsequent complications from occurring and ensures a rapid and satisfactory evolution of patients who suffer from it(AU)

ABSTRACT

ABSTRACT Sophisticated imaging systems have helped to redefine the clinical presentation of acute macular neuroretinopathy and have markedly enhanced diagnostic sensitivity. The proposed mechanism of paracentral acute middle maculopathy is related to ischemia at the level of the superficial and deep retinal capillary plexi. This is a case report of a patient who developed an acute macular neuroretinopathy after an uneventful angioplasty with stents in the coronary artery.


RESUMO Sistemas de imagem sofisticados ajudaram a redefinir a apresentação clínica da neurorretinopatia macular aguda e têm sensibilidade diagnóstica marcadamente aumentada. A maculopatia média aguda paracentral tem sido relacionada à isquemia ao nível dos plexos capilares superficial e profundo da retina. Este é um relato de caso de paciente que desenvolveu uma neurorretinopatia macular aguda após uma cirurgia de angioplastia com stents da artéria coronária sem complicações.

ABSTRACT

Resumen Objetivo: La dispersión transmural de la repolarización ventricular (DTMRV) es un factor de riesgo para muerte en pacientes con síndrome isquémico coronario agudo (SICA). Con el objetivo de conocer el efecto de la realización de angioplastia sobre la DTMRV, se estudió la relación Tp-f/QTc en pacientes con SICA sometidos a angioplastia. Método: Se diseñó un estudio observacional, retrospectivo y descriptivo. Se incluyeron 150 pacientes (N = 150) con diagnóstico de SICA. Se valoró la relación Tp-f/QTc inicial y se evaluó su acortamiento posangioplastia. Como objetivo secundario, se comparó la asociación de dichos cambios en la relación Tp-f/QTc con la mortalidad cardiovascular y los eventos adversos cardiovasculares. Resultados: El promedio en la relación Tp-f/QTc inicial fue de 0.2529, mientras que posangioplastia fue de 0.2397. Por medio de prueba de rangos de Wilcoxon se evidenció un descenso significativo en la relación Tp-f/QTc posterior a la angioplastia, con un valor Z de −2.051 y una p < 0.04. En el análisis secundario se encontró que una Tp-f/QTc ≥ 0.29 posangioplastia es factor de riesgo para presentación de los siguientes eventos adversos: muerte intrahospitalaria (7.4 vs 0%; p < 0.003), nuevo SICA en seguimiento a 1 año (25.9 vs. 18.5%; p < 0.006) y reintervención en seguimiento a 1 año (29.6 vs. 15.0%; p < 0.002). Conclusiones: Existe un acortamiento significativo en la relación Tp-f/QTc posangioplastia en pacientes con SICA. Esta medida de la DTMRV puede servir como un predictor de muerte intrahospitalaria, eventos cardiovasculares y reintervención a 1 año en pacientes con SICA tratados con angioplastia.


Abstract Objective: Transmural Dispersion of Repolarization (TDR) is a Risk factor for Death in patients with Acute Coronary Syndrome (ACS). In order to know the effect of angioplasty on TDR, the Tp-e/QTc ratio was studied in patients with ACS undergoing angioplasty. Method: An observational, retrospective and descriptive study was designed. 150 patients (N = 150) with diagnosis of ACS were included. The initial Tp-e/QTc ratio was assessed and then its post-angioplasty shortening was evaluated. As a secondary objective, we compared the association of these Tp-e/QTc ratio changes with cardiovascular mortality and cardiovascular adverse events. Results: The average in the initial Tp-e/QTc ratio was 0.2529, while post-angioplasty was 0.2397. Through a Wilcoxon rage test, a significant decrease in the Tp-e/QTc ratio after angioplasty was observed, with a Z value of −2.051 and p < 0.04. In the secondary analysis, it was found that a Tp-e/QTc ≥ 0.29 post-angioplasty is a risk factor for presenting the following adverse events: in-hospital death (7.4 vs. 0%; p < 0.003), new ACS in 1-year follow-up (25.9 vs. 18.5%; p < 0.006), and reintervention in 1-year follow up (29.6 vs. 15%; p < 0.002). Conclusions: There is a significant shortening in the Tp-e/QTc ratio post-angioplasty in patients with ACS. This measure of TDR can serve as a predictor of in-hospital death, cardiovascular events and 1-year reintervention in patients with ACS treated initially by angioplasty.

Requiere alta sospecha y medidas rápidas. Caso clínico: Hombre de 41 años con diagnóstico de infarto agudo de miocardio (IAM) con supradesnivel ST (SDST) que fue trombolizado y derivado para angioplastía, que sufre sangrado en antebrazo derecho posprocedimiento y evoluciona con síndrome compartimental que requiere de fasciotomía en volar y medial. Discusión: La entidad clínica es rara en este contexto, por ende, requiere alta sospecha basándose principalmente en dolor de inicio súbito con aumento de volumen. El tratamiento es fasciotomía de urgencias. De no pesquisarse a tiempo puede evolucionar con severas alteraciones neuromusculares llevando a trastornos de la anatomía de la mano.


Introduction: The compartment syndrome is caused by an increase on the compartment pressure that exceed the perfusion pressure. In coronary postangioplasty context it is a rare entity. Requires a high suspicion and to take fast steps. Clinical case: Forty-one years old man with a STEMI thrombolysed and derived to angioplasty suffered a post-procedure bleeding on his right forearm and evolved with a compartment syndrome that required a volar and medial fasciotomy. Discussion: The clinical entity is rare in this context, so require a high suspicion based basically on sudden pain with an increase of volume. The treatment is the urgent fasciotomy. To not diagnose it at time could evolve with severe neuromuscular disorders and hand anatomy disorders.

ABSTRACT

Objective: to assess post-angioplasty myointimal hyperplasia in iliac artery of rabbits treated with extract of Moringa oleifera leaves. Methods : we conducted a randomized trial in laboratory animals for five weeks of follow-up, developed in the Vivarium of Pharmaceutical Technology Laboratory of the Universidade Federal da Paraíba. We used rabbits from the New Zealand breed, subjected to a hypercholesterolemic diet and angioplasty of the external iliac artery, randomized into two groups: M200 Group (n=10) - rabbits treated with 200mg/kg/day of Moringa oleifera leaves extract orally; SF group (n=10) - rabbits treated with 0.9% saline orally. After five weeks, the animals were euthanized and the iliac arteries prepared for histology. Histological sections were analyzed by digital morphometry. Statistical analysis was performed using the Student's t test. The significance level was 0.05. Results : there was no significant difference in myointimal hyperplasia between M200 and SF groups when comparing the iliac arteries submitted to angioplasty. Conclusion : there was no difference of myointimal hyperplasia between groups treated with saline and Moringa oleifera after angioplasty.

ABSTRACT

Resumo Introdução: A prevenção da nefropatia induzida por contraste (NIC) é difícil nas situações de emergência, tornando essenciais estudos sobre NIC em pacientes submetidos à angioplastia de urgência. Objetivo: Determinar a incidência e fatores associados à NIC em pacientes com infarto agudo do miocárdio (IAM) submetidos à angioplastia nas primeiras 12 horas após início dos sintomas. Métodos: Foram estudados 201 casos consecutivos de IAM com supradesnivelamento do segmento ST com menos de 12 horas de evolução. Todos os pacientes foram submetidos ao mesmo protocolo de angioplastia. A NIC foi definida como elevação absoluta da creatinina de pelo menos 0,5 mg/dL e/ou aumento relativo da creatinina de 25% em relação ao valor basal no período entre 48 e 72 horas após a administração do contraste. As variáveis que diferiram entre os pacientes com e sem NIC na análise univariada foram analisadas por regressão logística. Resultados: A amostra foi formada por 135 (67,2%) homens e 66 (32,8%) mulheres com idade média de 66,6 ± 11,7 anos. A incidência de NIC foi de 23,8%. Na análise univariada os pacientes com NIC eram mais idosos e com maior frequência de fração de ejeção do ventrículo esquerdo ≤ 40% e da classificação Killip ≥ 2. Na análise multivariada não foram encontrados preditores independentes de NIC. Conclusão: A NIC acomete » dos pacientes com IAM submetidos à angioplastia sem variáveis preditoras. Esse resultado ressalta a necessidade de medidas preventivas para NIC após uso de contraste em angioplastia de urgência.


Abstract Introduction: The prevention of contrast-induced nephropathy (CIN) is difficult in emergency situations, making it essential to study CIN in patients submitted to urgent angioplasty. Objective: To determine the incidence and associated factors to CIN in patients with myocardial infarction (MI) submitted to primary angioplasty in the first 12 hours after onset of symptoms. Methods: We studied 201 consecutive cases of MI with ST-segment elevation with less than 12 hours of evolution. All patients were submitted to the same angioplasty protocol. CIN was defined as an absolute increase of creatinine of at least 0.5 mg/dL and/or a relative increase of creatinine of 25% in relation to baseline in a period between 48 and 72 hours after contrast administration. The variables that differed between patients with and without CIN in univariate analysis were analyzed by logistic regression. Results: The sample was formed by 135 (67.2%) men and 66 (32.8%) women, with mean age of 66.6 ± 11.7 years. The incidence of CIN was 23.8%. In univariate analysis the patients with CIN were older and had higher frequency of left ventricular ejection fraction ≤ 40% and Killip classification ≥ 2. In multivariate analysis, we did not find independent predictors of CIN. Conclusion: CIN occurred in » of the patients with MI submitted to angioplasty without predictor variables. This finding highlights the need for CIN preventive measures after contrast use in emergency angioplasty.

ABSTRACT

Al uso del clopidogrel se han agregado nuevos antiagregantes como prasugrel y ticagrelor. El objetivo de este estudio fue comparar la incidencia de eventos isquémicos y hemorrágicos en pacientes que han recibido clopidogrel o prasugrel.Se incluyeron de manera consecutiva todos los pacientes con angioplastia durante la internación por síndrome coronario agudo entre diciembre 2011 y diciembre 2012.Fueron incluidos 398 pacientes. No se observaron diferencias en la mortalidad de causa cardiovascular (clopidogrel 2.5% vs. prasugrel 2.9%, p = 0.48). El grupo prasugrel presentó una reducción en la tasa de infarto (1.9% vs. 6.8%, p = 0.01) con sangrado totales (18.5% vs. 8.5%, p = 0.001) a expensas de sangrados menores (12.4% vs. 3.4%, p < 0.001), sin diferencia en sangrados mayores (p = 0.27) y sangrados con peligro de vida (p =.0.20). Por análisis multivariado los predictores independientes de mortalidad cardiovascular fueron edad (odds ratio 1.08, intervalo de confianza, IC, 95% 1.02-1.16, p = 0.02) insuficiencia renal (odds ratio 6.98, IC 95% 1.23-39.71, p < 0.0001). En cuanto al sangrado total se identificaron la edad (odds ratio 1.06, IC 95% 1.02-1.09, p = 0.002), elevación del segmento ST (odds ratio 1.99, IC 95% 1.05-3.79, p = 0.02), insuficiencia renal (odds ratio 3.32, IC 95% 1.62-6.78, p = 0.002) y utilización de prasugrel (odds ratio 3.97, IC 95% 1.87-8.41, p < 0.0001). La utilización de prasugrel se asocia a una menor tasa de infarto agudo de miocardio al año de seguimiento, con incremento de hemorragias menores. No se observaron diferencias significativas en la mortalidad cardiovascular entre ambos grupos.


Greater antithrombotic potency new antiplatelet agents have been added such as prasugrel (PR) and ticagrelor to the traditional use of clopidogrel (CL) in the treatment of acute coronary syndrome (ACS). This study was aimed at comparing the incidence of long term ischemic and hemorrhagic events in patients treated with CL or PR during hospitalization. Retrospective ACS data base analysis performed by our cardiology service was completed prospectively. There were consecutively included all patients with percutaneous coronary intervention (PCI) during hospitalization due to ACS from December 2011 thru December 2012. A total of 398 ACS patients who underwent PCI with stent implantation were recruited. No differences in cardiovascular related deaths were observed in both groups (PR 2.9% vs. CL 2.5%, p = 0.48). PR group showed less re-infraction (1.9% vs. 6.8%, p = 0.01) with more total bleedings (18.5% vs. 8.5%, p = 0.001) and minor bleedings (12.4% vs. 3.4%, p < 0.001) with no differences in major and life threatening bleedings (p = ns). Multivariate analysis showed that independent predictors of cardiovascular mortality were age (OR 1.08, CI 95% 1.02-1.16) and renal failure (OR 6.98, CI 95% 1.23-39.71). Independent predictors for total bleeding were age (OR 1.06, CI 95% 1.02-1.09),ST segment elevation myocardial infarction (OR 1.99, CI 95% 1.05-3.79), renal failure (OR 3.32, CI 95% 1.62-6.78) and prasugrel use (OR 3.97, CI 95% 1.87-8.41). Use of prasugrel, in the ACS that requires PCI with stent, is associated with a lower myocardial infarction a year after follow-up, and it also leads to an increase of milder hemorrhage. No significant differences were observed in the cardiovascular mortality of both groups.

ABSTRACT

PURPOSE: During carotid angioplasty and stenting (CAS), hemodynamic instability (HDI) can occur, possibly causing post-procedural ischemic complications. The goal of this study was to investigate the risk factors of HDI focusing on characteristics of plaque. MATERIALS AND METHODS: Thirty nine CAS patients were retrospectively evaluated for HDI. Prolonged HDI that lasted over 30 minutes was analyzed in relation to characteristics of calcified plaque. RESULTS: Nineteen (48.7%) patients had HDI. Ten of the 19 had both bradycardia and hypotension, and nine had only bradycardia. All bradycardia was treated well with a transcutaneous temporary cardiac pacemaker. But eight patients presented with prolonged hypotension in spite of recovery of bradycardia. Calcified plaque was a related factor associated with HDI (odds ratio, 8.571; 95% confidence interval, 1.321-55.62; p=0.024). Extensive and eccentric type calcified plaques were associated with prolonged hypotension (p=0.04, and p=0.028, respectively). CONCLUSION: The calcification of plaque is a predictable factor of HDI during CAS, and its extensive and eccentric calcified plaques may be related to prolonged HDI.

ABSTRACT

Pacientes octogenários submetidos à angioplastia carotídea apresentam maior incidência de eventos neurológicos quando comparados a grupos de pacientes mais jovens e a grupos da mesma faixa etária submetidos à endarterectomia carotídea. A maior taxa de complicações pode ser explicada por fatores anatômicos e anatomopatológicos que aumentam a dificuldade técnica e o risco de ateroembolismo do procedimento endovascular. O procedimento foi realizado no centro cirúrgico, com o paciente em decúbito dorsal e sob anestesia geral. Realizamos acesso cirúrgico transverso limitado, na base do pescoço à direita, com dissecção, identificação e reparo da artéria carótida comum e veia jugular interna. Foram administradas 10.000 U de heparina e puncionada a carótida comum pela técnica de Seldinger com introdução de bainha 8F em sentido cranial. Na sequência, foi puncionada a veia jugular interna com instalação de bainha 8F em sentido caudal. Em seguida, ambas as bainhas foram conectadas, utilizando-se um segmento de equipo de soro. A carótida comum foi fechada por cadarço duplo de silicone e o fluxo retrógrado pela carótida interna foi estabelecido. Subsequentemente, foi introduzido fio guia 0.014 x 190 cm com cruzamento da lesão, realizando-se angioplastia com balão 5 x 20 mm e em seguida stent (Wallstent® 7 x 50 - Boston Scientific) foi introduzido, posicionado e liberado. A angioplastia carotídea com reversão de fluxo, por via transcervical, constitui estratégia de proteção cerebral custo-eficiente e com menor potencial emboligênico em pacientes octogenários com anatomia desfavorável.


Octogenarian patients submitted to carotid angioplasty present higher incidence of neurological events when compared to younger patients and to patients in this same age submitted to carotid endarterectomy. The higher complication rate could be related to anatomic and anatomopathological factors that increase technical difficulties and atheroembolic risk associated with the endovascular procedure. At the operating room, the patient was in dorsal decubitus position and submitted to general anesthesia. Limited transversal surgical access was carried out on the right neck base, with dissection, identification and restoration of the common carotid artery and internal jugular vein. A 8F sheath was implanted cranially oriented into the common carotid by Seldinger technique after endovenous injection of 10.000 UI of heparin. Another 8F sheath was implanted into the internal jugular vein in caudal orientation. Both sheath were connected by the use of infusion set segment. The common carotid artery was clamped with a silastic double lace, establishing reversion of blood flow in the internal carotid artery. The lesion was crossed by 0.014 x 190 cm wire and the carotid angioplasty was performed employing a 5 x 20 mm ballon and a stent (Wallstent® 7 x 50 - Boston Scientific) was introduced, positioned and released. Carotid angioplasty with transcervical flow reversal is a cost effective brain protection strategy, associated to low embolic potential in octagenarian patients with unfavorable anatomy.

ABSTRACT

Patients with CLI are typically elderly with multiple co-morbidity and limited life expectancy and therefore, a procedure, which is minimally invasive with reduced morbidity and mortality but lesser long-term patency, may be more appropriate than a more invasive procedure with better long-term patency. This study was conducted to assess the outcome of endovascular angioplasty in treating infragenicular arterial disease in Egyptian diabetic patients with critical limb ischemia. Forty nine patients with [51] limbs presented with critical limb ischemia were subjected to endovascular tibial angioplasty, of which 40 patients had gangrene, 6 patients had ischemic ulcers, 3 had rest pain and 2 with severe foot infections. Overall, 79 arteries of the infra-popliteal [7] and iliac [1] were associated. Technical success was evaluated on angiography at the end of the procedure revascularization of at least one of 3 leg vessels with re-establishment of arterial flow to the foot was regarding technical success. The technical success rate of angioplasty in the revascularization of infra-popliteal vessles was 92%. In the 4 [8%] patients with a technical failure, two patients were treated conservatively and two patients were lost to follow up during the study. The clinical success rate was [80%], healing of an ulcer or wound after minor amputation. The cumulative limb salvage rate quantified by Kaplan-Meier life table analysis was at 20 month 80%. The per-cutaneous tibial angioplasty of infra-popliteal artery stenoses and occlusions is considered as an effective and safe therapy modality to avoid below the-knee amputation in patients with limb threatening ischemia

ABSTRACT

Concomitant coronary and peripheral angioplasty is a more frequently reported situation. Patient's outcome is significantly conditioned by access site complications especially in femoral and brachial approaches. The radial artery access is a safe and a well established alternative in coronary interventions and could be suitable for many peripheral angioplasty cases, thanks to devices enhancement. Rport a new case. We report the case of a 56-year-old woman with multivessel coronary artery disease, significant left subclavian [SCA] and bilateral renal arteries stenoses. Because of a severe resistant hypertension and prior to scheduled coronary bypass surgery a triple angioplasty of left renal artery, SCA, and left anterior descending [LAD] was attempted. Stenting of the three sites was successful in the same procedure through the left radial artery route. Radial artery access in peripheral, combined and complex percutaneous transluminal angioplasty seems to be suitable and safe. However, prospective clinical trials are still lacking

ABSTRACT

A associação entre fatores de risco cardiovascular (FRCV) na pós-menopausa e o antecedente de irregularidade menstrual no menacme foi avaliado em estudo caso-controle envolvendo 414 mulheres na pós-menopausa com idade de 60,4 ± 5,5 anos e IMC de 25,3 ± 4,7 kg/m². As variáveis consideradas foram: caracterização do ciclo menstrual entre 20 e 35 anos (independente) e relato atual sobre ocorrência de hipertensão arterial, dislipidemia, diabetes mellitus e doença arterial coronariana (dependentes). Utilizou-se o teste qui-quadrado e modelos de regressão logística, ajustados para outras variáveis implicadas no risco para doenças CV, com nível de significância 5 por cento. Observou-se que mulheres que relataram irregularidade menstrual prévia estiveram associadas com risco aumentado para ocorrência de algum FRCV [odds ratio ajustado (OR)= 2,14; IC-95 por cento= 1,02­4,48], quando comparadas àquelas com ciclos regulares. Análise estratificada demonstrou as seguintes associações significativas com o antecedente de irregularidade menstrual: hipertensão arterial (OR= 2,4; 95 por cento IC= 1,39­5,41), hipercolesterolemia (OR= 2,32; 95 por cento IC= 1,17­4,59), hipertrigliceridemia (OR= 2,09; 95 por cento IC= 1,10­4,33) e angioplastia coronariana (OR= 6,82; 95 por cento IC= 1,44­32,18). Os dados sugerem que o antecedente de irregularidade menstrual, indicativo da ocorrência da síndrome dos ovários policísticos na idade reprodutiva, pode estar relacionado com aumento do risco para doenças CV na pós-menopausa.


To evaluate the association between cardiovascular risk factors (CVRF) during postmenopausal years and previous menstrual irregularity during reproductive years, we performed a case-control study in 414 postmenopausal women (mean age 60.4 ± 5.5 years; BMI 25.3 ± 4.7 kg/m²). The variables assessed were: menstrual cycle characteristics at age 20­35y (independent) and records of arterial hypertension, dyslipidemia, diabetes mellitus, and coronary heart disease (dependent). Statistical analysis used the chi-square test and logistic regression, adjusting for potential confounders for cardiovascular risk, with significance set at 5 percent. Women reporting previous menstrual irregularity were associated with increased risk for some CVRF [adjusted odds ratio (OR) 2.14; CI-95 percent= 1.02­4.48], when compared with those reporting regular menstrual cycles. Stratified analysis demonstrated significant associations of previous menstrual irregularity with: arterial hypertension [OR= 2.74; CI-95 percent= 1.39­5.41), hypercholesterolemia (OR= 2.32; CI-95 percent= 1.17­4.59), hypertriglyceridemia (OR= 2.09; CI-95 percent=1.10­4.33), and coronary angioplasty (OR= 6.82; CI-95 percent= 1.44­32.18). These data suggest that a prior history of menstrual irregularity, as indicative of polycystic ovary syndrome, may be related to increased risk for CVD during postmenopausal years.

ABSTRACT

OBJETIVO: Descrever os eventos adversos ocorridos durante e após angioplastia coronária (ATC), possivelmente relacionados ao reuso de produtos médico-hospitalares, além de quantificar e identificar os motivos de descarte em relação ao primeiro uso e ao reuso. MÉTODO: Foram estudados 60 pacientes, sendo que 29 (48,3 por cento) apresentavam angina instável, 27 (45 por cento) IAM e quatro (6,7 por cento) outros diagnósticos. Durante o procedimento e na permanência na Unidade Intensiva Coronariana, atentou-se à possibilidade de ocorrência dos eventos adversos febre, hipertensão, hipotensão, calafrios, sudorese, sangramento, náuseas e vômitos. Foram avaliados sete produtos médico-hospitalares: introdutor, cateter-guia, fio-guia 0.35, fio-guia 0.014, cateter- balão para angioplastia, seringa com manômetro para insuflar balão (indeflator) e torneira de três vias (manifold). No total de produtos (76 de primeiro uso e 410 reprocessados), verificou-se se houve descarte e se isto ocorreu antes ou durante o procedimento e quais os motivos para tanto. Utilizou-se o teste Qui Quadrado, admitindo-se erro alfa de 5 por cento. RESULTADOS: Vinte e seis pacientes apresentaram eventos adversos. A hipotensão foi o evento mais prevalente e ocorreu em 11(18,3 por cento) casos. Não houve, porém, significância estatística entre o evento adverso hipotensão e reuso ou não dos produtos médico-hospitalares. Por não estarem íntegros, foram descartados três produtos de primeiro uso e 55 produtos dos reutilizados. CONCLUSÃO: Os eventos adversos apresentados pelos pacientes submetidos à angioplastia não estão associados ao reuso dos produtos médico-hospitalares. A integridade e funcionalidade foram os motivos principais de descarte.


OBJECTIVE: To describe the adverse effects that occur during and after percutaneous transluminal coronary angioplasty (PTCA) possibly related to the reuse of medical equipment. An additional objective is to quantify and identify the reasons of discard in respect to the brand-new and reuse of medical equipment. METHOD: Sixty patients were studied (48.3 percent with unstable angina, 45 percent with acute myocardial infarction and 6.7 percent with other diagnoses). During the procedure and stay in the Intensive Coronary Unit, the occurrence of fever, hypotension or hypertension, chills, sudoresis, bleeding, nausea and vomits were observed. Seven products were evaluated: catheter introducer, catheter guides (0.35 and 0.014), catheter balloons for angioplasty, indeflators and manifolds. In total, 76 brand-new and 410 reused apparatuses were studied to verify the occurrence of discard, whether this happened before or during the procedure and for what reasons. P-values < 0.05 were considered signicant. RESULTS: Twenty-six patients presented adverse effects. Hypotension was the most common seen in 11(18.3 percent) cases. There was no significant association between this adverse effect and reuse or not of the equipment. Three brand-new products and 55 of the reused products were discarded as they were incomplete. CONCLUSION: The adverse effects presented by patients submitted to coronary vessel angioplasty were not associated to the reuse of the medical equipment. The integrity and functionality were the main reasons of discard.

ABSTRACT

OBJETIVO: Tratamento endovascular - angioplastia carotídea com stent (ACS) - tem se mostrado como opção atual no tratamento da estenose da artéria carótida em pacientes considerados de alto risco para endarterectomia de carótida (ECA). Este trabalho reporta a experiência do Instituto de Cirurgia Vascular e Endovascular (ICVE) de São Paulo nos casos de ACS em pacientes de alto risco. MATERIAL E MÉTODO: Foi realizado um estudo retrospectivo descritivo baseado na análise dos prontuários de 113 pacientes (84 homens e 29 mulheres) submetidos a 130 procedimentos de ACS pelo ICVE, no período de março de 2000 a junho de 2004. A idade média dos pacientes foi de 74 anos (variando de 51 a 86 anos). Os pacientes assintomáticos (55 por cento) apresentavam estenose > 75 por cento, enquanto nos sintomáticos (45 por cento) as lesões encontradas foram > 70 por cento. Foi indicado ACS nos seguintes pacientes: alto risco para ECA (45 por cento), reestenose pós-ECA (15 por cento), estenose carotídea severa bilateral (14 por cento), oclusão da carótida contralateral (12 por cento), bifurcação alta (no nível ou acima da segunda vértebra cervical) (6 por cento), estenose pós-radioterapia (5 por cento) e pescoço hostil (3 por cento). As lesões encontradas localizavam-se na bifurcação carotídea (46 por cento), carótida interna (32 por cento), origem da artéria carótida comum (9 por cento), tronco braquiocefálico (8 por cento) e artéria carótida comum (5 por cento). RESULTADO: Foi observado um total de sete eventos neurológicos (cinco casos de acidente vascular encefálico e dois pacientes que apresentaram ataque isquêmico transitório). A taxa de óbito foi de 0 por cento. A taxa total de complicações (acidente vascular encefálico, acidente isquêmico transitório, óbito) foi de 5,3 por cento. CONCLUSÃO: ACS demonstrou ser um procedimento com baixa taxa de complicações, sendo uma opção segura e eficaz nos pacientes de alto risco para ECA.

ABSTRACT

El infarto cerebral agudo representa una emergencia clínica, potencialmente reversible si se trata con trombolisis durante las primeras 3 a 6 horas de evolución. La trombolisis tiene muchas ventajas para el paciente, pero también representa algunos riesgos como el desarrollo de una hemorragia intracerebral. Como consecuencia de un intenso trabajo de investigación contamos hoy dia con importantes avances en diferentes técnicas de neuro-imágenes para evaluar la isquemia cerebral potencialmente reversible, incluyendo la resonancia magnética (RM) con difusión-perfusión, la tomografía computada (CT) con perfusión y estudios neurofuncionales como el PET y el SPECT cerebral. Este trabajo comunica los resultados en la evaluación pre y post tratamiento endovascular en una serie de pacientes que presentaron isquemia cerebral aguda y luego fueron tratados con trombolisis intra-arterial cerebral. MÉTODO: 16 pacientes fueron tratados de forma aguda por un infarto cerebral agudo siguiendo el siguiente protocolo: 1) Admisión y evaluación completa neurológica. 2) TAC cerebral para descartar presencia de hemorragia cerebral o de un infarto cerebral establecido. 3) Inyección endovenosa de 1100MBq Tc99mm HMPAO (Ceretecmr) 4) Angiografía cerebral convencional y trombolisis intra-arterial cerebral con tPA y posible angioplastía y colocación de stent. 5) Adquisición de imágenes de NeuroSPECT para evaluar penumbra isquémica (resultados pre-terapia) 6) 14 de 16 pacientes recibieron NeuroSPECT de control a las 24 horas (resultados post-terapia). La adquisición de imágenes de NeuroSPECT fue inmediatamente después de la trombolisis utilizando una cámara de doble cabezal, Siemens ECAM, SHR colimador utilizando protocolo habitual. Las imágenes fueron procesadas utilizando un software Neurogam de Segami Corp. previamente reportado en Alasbimn Journal 2(7):Abril 2000. http://www.alasbimnjournal.cl El análisis estadístico consistió en 1) normalización del volumen cerebral de acuerdo al mapa.
