ABSTRACT

Abstract Background: Overweight and obesity (O/O) generate lipotoxicity of the cardiac fiber and increase the incidence and progression of aortic valve stenosis. The low cardiac output syndrome (LCOS) is a timing complication after to aortic valve replacement (AVR) surgery. Objective: The objective of the study was to investigate if body mass index (BMI) kg/m2 is a risk factor associated with LCOS and mortality in the post-operative period of AVR. Methods: A historic cohort study was designed, including patients with severe aortic stenosis (SAS), who were subjected to AVR. Results: 152 patients were included, 45 (29.6%), with normal weight (NW), 60 were overweight (39.5%), and 47 obese (30.9%). The prevalence of systemic hypertension (HT) was higher in O/O (p < 0.0001). Incidence of LCOS was 44.7%, being more frequent in the O/O groups compared to the NW group, 43.3%, 68.1%, and 22.2%, respectively, (p < 0.05 in overweight and p < 0.0001 in the obese). Assessing the presence or absence of LCOS associated with BMI as a numerical variable, we found that women, HT, BMI, left ventricular mass, and valve size, were associated with LCOS (p < 0.02, p < 0.02, p < 0.001, p < 0.032, and p < 0.045, respectively). Mortality was higher in patients who had LCOS (p < 0.02). Multivariate model showed that BMI was an independent risk factor for LCOS (odds ratio [OR] 1.21 [95% CI 1.08-1.35], p < 0.001). Conclusion: BMI is a risk factor associated to LCOS in the post-operative period of AVR in patients with SAS.


Resumen Antecedentes: El sobrepeso y la obesidad (O/O) generan lipotoxicidad de la fibra cardíaca y aumentan la incidencia y progresión de la estenosis de la válvula aórtica. El síndrome de bajo gasto cardíaco (SBGC) es una complicación postquirúrgica de la cirugía de reemplazo de válvula aórtica (RVA). Objetivo: Investigar si el índice de masa corporal kg/m2 (IMC) es un factor de riesgo asociado con SBGC y mortalidad en el postoperatorio de RVA. Métodos: Se diseñó un estudio de cohorte histórico, que incluyó pacientes con estenosis aórtica importante (EAI), que fueron sometidos a RVA. Resultados: Se incluyeron 152 pacientes, 45 (29.6%), con peso normal (N), 60 tenían sobrepeso (39.5%) y 47 obesos (30.9%). La prevalencia de hipertensión sistémica (HT) fue mayor en O/O (p < 0.0001). La incidencia de SBGC fue del 44.7%, siendo más frecuente en los grupos O/O en comparación con el grupo N, 43.3%, 68.1%, 22.2% respectivamente, (p < 0.05 en sobrepeso y p < 0.0001 en obesos). Al evaluar la presencia o ausencia de SBGC asociado con el IMC como una variable numérica, encontramos que las mujeres, HT, IMC, masa ventricular izquierda y tamaño de la válvula, se asociaron con SBGC (p < 0.02, p < 0.02, p < 0.001, p < 0.032, p < 0.045, respectivamente). La mortalidad fue mayor en pacientes con SBGC (p < 0.02). El modelo multivariado mostró que el IMC fue un factor de riesgo independiente asociado a SBGC [OR 1.21 (IC 95% 1.08-1.35), p < 0.001]. Conclusión: El IMC es un factor de riesgo asociado a SBGC en el postoperatorio de RVA en pacientes con EAI.

ABSTRACT

Resumen Antecedentes y objetivos: El sistema de calificación APACHE II permite predecir la mortalidad intrahospitalaria en terapia intensiva. Sin embargo, no está validado para cirugía cardíaca, ya que no posee buena capacidad diferenciadora. El objetivo es determinar el valor pronóstico de APACHE II en el postoperatorio de procedimientos cardíacos. Materiales y métodos: Se analizó en forma retrospectiva la base de cirugía cardíaca. Se incluyó a pacientes intervenidos entre 2017 y 2018, de los cuales se calculó la puntuación APACHE II. Se utilizó curva ROC para determinar el mejor valor de corte. El punto final primario fue mortalidad intrahospitalaria. Como puntos finales secundarios se evaluó la incidencia de bajo gasto cardíaco (BGC), accidente cerebrovascular (ACV), sangrado quirúrgico y necesidad de diálisis. Se realizó un modelo de regresión logístico multivariado para ajustar a las variables de interés. Resultados: Se analizó a 559 pacientes. La media del sistema de calificación APACHE II fue de 9.9 (DE 4). La prevalencia de mortalidad intrahospitalaria global fue de 6.1%. El mejor valor de corte de la calificación para predecir mortalidad fue de 12, con un área bajo la curva ROC de 0.92. Los pacientes con APACHE II ≥ 12 tuvieron significativamente mayor mortalidad, incidencia de BGC, ACV, sangrado quirúrgico y necesidad de diálisis. En un modelo multivariado, el sistema APACHE II se relacionó de modo independiente con mayor tasa de mortalidad intrahospitalaria (OR, 1.14; IC95%, 1.08-1.21; p < 0.0001). Conclusiones: El sistema de clasificación APACHE II demostró ser un predictor independiente de mortalidad intrahospitalaria en pacientes que cursan el postoperatorio de cirugía cardíaca.


Abstract Background and objectives: The APACHE II score allows predicting in-hospital mortality in patients admitted to intensive care units. However, it is not validated for patients undergoing cardiac surgery, since it does not have a good discriminatory capacity in this clinical scenario. The aim of this study is to determine prognostic value of APACHE II score in postoperative of cardiac surgery. Materials and methods: The study was performed using the cardiac surgery database. Patients undergoing surgery between 2017 and 2018, with APACHE II score calculated at the admission, were included. The ROC curve was used to determine a cut-off value The primary endpoint was in-hospital death. Secondary endpoints included low cardiac output (LCO), stroke, surgical bleeding, and dialysis requirement. A multivariable logistic regression model was developed to adjust to various variables of interest. Results: The study evaluated 559 patients undergoing cardiac surgery. The mean of APACHE II Score was 9.9 (SD 4). The prevalence of in-hospital death was 6.1%. The best prognostic cut-off value for the primary endpoint was 12, with a ROC curve of 0.92. Patients with an APACHE II score greater than or equal to 12 had significantly higher mortality, higher incidence of LCO, stroke, surgical bleeding and dialysis requirement. In a multivariate logistic regression model, the APACHE II score was independently associated with higher in-hospital death (OR, 1.14; 95CI%, 1.08-1.21; p < 0.0001). Conclusions: The APACHE II Score proved to be an independent predictor of in-hospital death in patients undergoing postoperative cardiac surgery, with a high capacity for discrimination.

ABSTRACT

Abstract Background and objectives: The perioperative cardiac arrest (CA) and mortality rates in Brazil, a developing country, are higher than in developed countries. The hypothesis of this review was that knowledge of the epidemiology of perioperative CA and mortality in Brazil enables the comparison with developed countries. The systematic review aimed to verify, in studies conducted in Brazil, the epidemiology of perioperative CA and mortality. Method and results: A search strategy was carried out on different databases (PubMed, EMBASE, SciELO and LILACS) to identify observational studies that reported perioperative CA and/or mortality up to 48 hours postoperatively in Brazil. The primary outcomes were data on epidemiology of perioperative CA and mortality. In 8 Brazilian studies, there was a higher occurrence of perioperative CA and mortality in males; in extremes of age; in patients in worse physical status according to the American Society of Anesthesiologists (ASA); in emergency surgeries; in general anesthesia; and in cardiac, thoracic, vascular, abdominal and neurological surgeries. The patient's disease/condition was the main triggering factor, with sepsis and trauma as the main causes. Conclusions: The epidemiology of both perioperative CA and mortality events reported in Brazilian studies does not show important differences and, in general, is similar to studies in developed countries. However, sepsis represents one of the major causes of perioperative CA and mortality in Brazilian studies, contrasting with studies in developed countries in which sepsis is a secondary cause.


Resumo Justificativa e objetivos: As incidências de parada cardíaca (PC) e de mortalidade perioperatória no Brasil, um país em desenvolvimento, são mais elevadas em relação às dos países desenvolvidos. A hipótese desta revisão é que o conhecimento da epidemiologia de PC e de mortalidade perioperatória no Brasil possibilita sua comparação com a dos países desenvolvidos. A revisão sistemática teve como objetivo verificar, em estudos realizados no Brasil, a epidemiologia de PC e de mortalidade perioperatória. Conteúdo: Realizou-se estratégia de busca em diferentes bases de dados (PubMed, EMBASE, SciELO e LILACS) para a identificação de estudos observacionais que reportaram PC e/ou mortalidade perioperatória até 48 horas pós-operatório no Brasil. Os desfechos primários foram dados de epidemiologia de PC e de mortalidade perioperatória. Em 8 estudos nacionais, identificou- se maior ocorrência de PC e de mortalidade perioperatória no sexo masculino, em extremos de idade, em pacientes em pior estado físico segundo a American Society of Anesthesiologists (ASA), em cirurgias de emergência, em anestesia geral, e em cirurgias cardíaca, torácica, vascular, abdominal e neurológica. A doença/condição do paciente foi o principal fator desencadeante, tendo como causas principais a sepse e o trauma. Conclusões: Nos estudos nacionais, a epidemiologia dos eventos tanto de PC como de mortalidade perioperatória não apresenta diferenças importantes, e de maneira geral, é semelhante à de estudos de países desenvolvidos. Entretanto, a sepse, nos estudos nacionais, representa uma das principais causas de PC e de mortalidade perioperatória, diferenciando-se dos estudos de países desenvolvidos nos quais a sepse é causa secundária.

ABSTRACT

Introdução: O fechamento de estomas, embora rotineiramente performado, ainda não pode ser considerado um procedimento simples. Nós reportamos, desta forma, a morbidade, mortalidade e fatores de riscos associados a este procedimento em um período de dez anos. Métodos: Revisão retrospectiva de 252 prontuários (149 homens; 103 mulheres), com uma média de 56 anos de idade (18 a 89 anos), que foram submetidos a fechamento de estomas, com análise de complicações clínicas e cirúrgicas, características relacionadas ao estoma, entre outros. Admissão em UTI, complicações precoces (até 30 dias) (classificação de Clavien-Dindo), e tardias, além de óbito, foram analisados. Os testes T de Student, ANOVA, Qui-Quadrado de Pearson, exato de Fischer e de Mann-Whitney foram utilizados para análise paramétrica e não-paramétrica. Resultados: Tumores colorretais (64%) e diverticulite (10%) foram as principais causas para a confecção do estoma. 112 (44,4%) dos pacientes tiveram pelo menos uma complicação cirúrgica. As complicações precoces foram infecção de ferida operatória (13%), fistula e deiscência anastomótica/intestinal (9%), abscessos de cavidade ou parede abdominais (8,3%); tardiamente houveram 36 casos de hérnia incisional (14,2%) e uma estenose intestinal (0,3%). Comorbidades levaram a 10% maior probabilidade de ter uma ou mais complicações cirúrgicas, e todas as cinco mortes ocorreram nestes pacientes (2%). Estomas de intestino grosso, maior tempo operatório e admissão em UTI estiveram significamente relacionados a aumento da morbidade. Conclusão: Pacientes com comorbidades e estomas de intestino grosso tiveram mais risco de complicações. Cuidados pré e perioperatórios, e melhor seleção de pacientes são importantes na redução da morbimortalidade.(AU)


Introduction: Although routinely performed, stoma closure cannot as yet be considered a simple procedure. We report here the morbidity, mortality and risk factors associated with this procedure over a 10-year period. Methods: The medical records of 252 patients (149 men; 103 women), with a mean age of 56 years (18 to 89 years), who underwent stoma closure were retrospectively reviewed for postoperative clinical and surgical complications, stoma-related features, among others. ICU admission, early surgical complications (within 30 days) according to the Clavien-Dindo classification, late surgical complications, and death were analyzed. Student's t-test, ANOVA, Pearson's chi-square test, Fisher's exact test, and MannWhitney U test were used for parametric and nonparametric data. Results: Colorectal tumors (64%) and diverticulitis (10%) were the main reasons for stoma surgery. Overall, 112 (44.4%) patients had at least one surgical complication. Early complications included surgical wound infection (13%), fistula and anastomotic/ intestinal dehiscence (9%), and abdominal wall or intra-abdominal abscesses (8.3%). Late complications included 36 (14.2%) cases of incisional hernia and one case (0.3%) of stricture. Patients with comorbidities were 10% more likely to have one or more surgical complications, and all 5 deaths occurred in these patients (2%). Large-bowel ostomies, longer operative time and ICU admission were significantly related to increased morbidity. Conclusion: Patients with an increased number of comorbidities and large-bowel ostomies are at higher risk for complications. Pre- and perioperative care and accurate patient selection are important to reduce morbidity and mortality.(AU)

ABSTRACT

Abstract Background and objectives: Perioperative management of femoral fractures in elderly patients has been studied to determine modifiable causes of complications and death. The aim of this study was to evaluate the mortality rate and its causes in the elderly population with FF. We also evaluated perioperative complications and their association with postoperative mortality. Method: In this prospective and observational study, we evaluated 182 patients, by questionnaire and electronic medical record, from the moment of hospitalization to one year after surgery. Statistical analyzes using the multivariate Cox proportional hazards model and Kaplan-Meier curves were performed to detect independent mortality factors. Results: Fifty-six patients (30.8%) died within one year after surgery, and the main cause of death was infection followed by septic shock. The main complication, both preoperatively and postoperatively, was hydroelectrolytic disorder. For every one-unit (one-year) increase in age, the odds ratio for death increased by 4%. With each new preoperative complication, the odds ratio for death increased by 28%. Patients ASA III or IV had a 95% higher odds ratio for death than patients ASA I or II. Conclusions: Increasing age and number of preoperative complications, in addition to ASA classification III or IV, were independent factors of increased risk of death in the population studied. The mortality rate was 30.8%, and infection followed by septic shock was the leading cause of death.


Resumo Justificativa e objetivos: O manejo perioperatório das fraturas de fêmur em pacientes idosos tem sido estudado com o intuito de determinar causas modificáveis de complicações e óbito. Este estudo tem por objetivo avaliar taxa de mortalidade e suas causas na população idosa com fraturas de fêmur. Avaliamos também complicações perioperatórias e sua associação com mortalidade pós-operatória. Método: Neste estudo prospectivo e observacional, avaliamos 182 pacientes, por questionário e prontuário eletrônico, desde o momento da internação até um ano após a cirurgia. Análises estatísticas pelo modelo multivariado de riscos proporcionais de Cox e curvas de Kaplan-Meier foram feitas para detectar fatores independentes de mortalidade. Resultados: Cinquenta e seis pacientes (30,8%) obituaram em até um ano de pós-operatório, sendo que a principal causa determinada de óbito foi infecção seguida de choque séptico. A principal complicação, tanto pré quanto pós-operatória, foi distúrbio hidroeletrolítico. Para cada aumento de uma unidade (em ano) na idade, a razão de chance de vir a óbito aumentou em 4%. A cada nova complicação pré-operatória apresentada, a razão de chance de óbito aumentou em 28%. Os pacientes ASA III ou IV apresentaram razão de chance de óbito, em um ano, 95% maior do que aqueles ASA I ou II. Conclusões: O aumento da idade e do número de complicações pré-operatórias, além da classificação de ASA III ou IV, foram fatores independentes de risco aumentado de óbito na população estudada. A taxa de mortalidade foi de 30,8%, sendo que a infecção seguida de choque séptico foi a principal causa determinada de óbito.

ABSTRACT

Background: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer. Aim: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve. Material and Methods: Retrospective cohort study with data obtained from a prospectively collected LT Program database. We included all LT performed at a single center from March 1994 to September 2017. The database gathered demographics, diagnosis, indications for LT, surgical aspects and postoperative courses. We constructed a cumulative summation test for learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30 days, and actuarial 1-, and 5-year survival rate were analyzed. Results: A total of 281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percent of patients were younger than 18 years old. The first, second and third indications for LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis and alcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in 51 cases (17%). The overall complication rate was 71%. Infectious and biliary complications were the most common of them (47 and 31% respectively). The LC-CUSUM curve shows that the first 30 patients corresponded to the learning curve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rates were 82 and 71.4%, respectively. Conclusions: Outcome improvement of a LT program depends on the accumulation of experience after the first 30 transplants and the peri-operative mortality directly impacted long-term survival.

ABSTRACT

Abstract Objective: To evaluate whether there is any difference on the results of patients treated with coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in the setting of ischemic heart failure (HF). Methods: Databases (MEDLINE, Embase, Cochrane Controlled Trials Register [CENTRAL/CCTR], ClinicalTrials.gov, Scientific Electronic Library Online [SciELO], Literatura Latino-americana e do Caribe em Ciências da Saúde [LILACS], and Google Scholar) were searched for studies published until February 2019. Main outcomes of interest were mortality, myocardial infarction, repeat revascularization, and stroke. Results: The search yielded 5,775 studies for inclusion. Of these, 20 articles were analyzed, and their data were extracted. The total number of patients included was 54,173, and those underwent CABG (N=29,075) or PCI (N=25098). The hazard ratios (HRs) for mortality (HR 0.763; 95% confidence interval [CI] 0.678-0.859; P<0.001), myocardial infarction (HR 0.481; 95% CI 0.365-0.633; P<0.001), and repeat revascularization (HR 0.321; 95% CI 0.241-0.428; P<0.001) were lower in the CABG group than in the PCI group. The HR for stroke showed no statistically significant difference between the groups (random effect model: HR 0.879; 95% CI 0.625-1.237; P=0.459). Conclusion: This meta-analysis found that CABG surgery remains the best option for patients with ischemic HF, without increase in the risk of stroke.

ABSTRACT

Abstract Prosthesis-patient mismatch (PPM) after surgical aortic valve replacement (SAVR) is an issue that has been overlooked (not to say neglected). Cardiac surgeons must bear in mind that this is a real problem that we must tackle. The purpose of this paper is to be a wake-up call to the surgical community by giving a brief overview of what PPM is, its incidence and impact on the outcomes. We also discuss the increasing role played by imaging for predicting and assessing PPM after SAVR (with which surgeons must become more acquainted) and, finally, we present some options to avoid PPM after the surgical procedure.

ABSTRACT

Background: Exclusive coronary revascularization with both mammary arteries could result in lower rates of adverse events in the long term. Aim: To describe the five-year evolution of a cohort of patients operated on with this technique. Material and Methods: Follow up analyzing survival of 73 patients aged 59 ± 9 years (82% men) who underwent exclusive coronary surgery with two mammary arteries between December 1,2010 and April 12,2017. We studied their clinical characteristics, surgical results, operative morbidity and mortality and adverse events up to June 30, 2018. Results: Six patients had two-vessel lesions and 67 three-vessel lesions. The operative risk calculated by additive and logistic EuroSCORE was 2.5 and 2.3%, respectively. A mean of 3.75 anastomoses /patient were performed, 116 with left mammary artery (73 to the anterior descending artery, 38 to a diagonal artery and 5 for other objectives) and 158 with right mammary artery (69 to a first marginal artery, 23 to a second marginal artery and 64 to posterior descending artery). There was one case of mediastinitis and one (1.5%) patient died. The mean follow-up was 64.6 ± 23.7 months. The 5-year survival was 90.4%. Conclusions: Coronary revascularization with two exclusive mammary arteries allowed a complete revascularization of the heart with a low rate of complications and adverse effects at five years.

ABSTRACT

Abstract Objective: This study sought to evaluate the impact of prosthesis-patient mismatch on the risk of perioperative and long-term mortality after mitral valve replacement. Methods: Databases were researched for studies published until December 2018. Main outcomes of interest were perioperative and 10-year mortality and echocardiographic parameters. Results: The research yielded 2,985 studies for inclusion. Of these, 16 articles were analyzed, and their data extracted. The total number of patients included was 10,239, who underwent mitral valve replacement. The incidence of prosthesis-patient mismatch after mitral valve replacement was 53.7% (5,499 with prosthesis-patient mismatch and 4,740 without prosthesis-patient mismatch). Perioperative (OR 1.519; 95%CI 1.194-1.931, P<0.001) and 10-year (OR 1.515; 95%CI 1.280-1.795, P<0.001) mortality was increased in patients with prosthesis-patient mismatch. Patients with prosthesis-patient mismatch after mitral valve replacement had higher systolic pulmonary artery pressure and transprosthethic gradient and lower indexed effective orifice area and left ventricle ejection fraction. Conclusion: Prosthesis-patient mismatch increases perioperative and long-term mortality. Prosthesis-patient mismatch is also associated with pulmonary hypertension and depressed left ventricle systolic function. The findings of this study support the implementation of surgical strategies to prevent prosthesis-patient mismatch in order to decrease mortality rates.

ABSTRACT

Abstract Objective: To analyze data related to surgical treatment in patients with congenital heart defects (CHD) and Down syndrome (DS) based on information from International Quality Improvement Collaborative Database for Congenital Heart Disease (IQIC). Methods: Between July 1, 2010 and December 31, 2017, 139 patients with CHD and DS underwent surgery at Hospital de Base and Hospital da Criança e Maternidade de São José do Rio Preto (FUNFARME)/Faculdade de Medicina de São José do Rio Preto - SP (FAMERP). A quantitative, observational and cross-sectional study was performed in which the pre, intra and postoperative data were analyzed in an IQIC database. The data included gender, age, prematurity, weight, preoperative procedures, diagnosis, associated cardiac and non-cardiac anomalies, Risk Adjustment for Congenital Heart Surgery (RACHS-1), type of surgery, cardiopulmonary bypass (CPB), perfusion time, aortic clamping time and CPB temperature, bacterial sepsis, surgical site infection and other infections, length of stay in intensive care unit (ICU), length of hospital stay and in-hospital mortality. Results: The most prevalent procedures were complete atrioventricular septal defect repair (58 - 39.45%), followed by closure of ventricular septal defect (36 - 24.49%). The RACHS-1 categories 1, 2, 3 and 4 were distributed as 22 (15%); 49 (33.3%); 72 (49%) and 4 (2.7%), respectively. There were no procedures classified as categories 5 or 6. Bacterial sepsis occurred in 10.2% of cases, surgical site infection in 6.1%, other infections in 14.3%. The median length of ICU stay was 5 days and the median length of hospital stay was 11 days. In-hospital mortality was 6.8%. Conclusion: Surgical treatment in patients with CHD and DS usually does not require highly complex surgical procedures, but are affected by infectious complications, resulting in a longer ICU and hospital length of stay with considerable mortality.

ABSTRACT

ABSTRACT Introduction: Obesity is a disease of high prevalence in Brazil and in the world, and bariatric surgery, with its different techniques, is an alternative treatment. Objective: To compare techniques: adjustable gastric band (AGB), sleeve gastrectomy), Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) analyzing leaks, bleeding, death, weight loss, resolution of type 2 diabetes, systemic arterial hypertension, dyslipidemia and obstructive sleep apnea. Methods: Were selected studies in the PubMed database from 2003 to 2014 using the descriptors: obesity surgery; bariatric surgery; biliopancreatic diversion; sleeve gastrectomy; Roux-en-Y gastric bypass and adjustable gastric banding. Two hundred and forty-four articles were found with the search strategy of which there were selected 116 studies through the inclusion criteria. Results: Excess weight loss (EWL) after five years in AGB was 48.35%; 52.7% in SG; 71.04% in RYGB and 77.90% in BPD. The postoperative mortality was 0.05% in the AGB; 0.16% on SG; 0.60% in RYGB and 2.52% in BPD. The occurrence of leak was 0.68% for GBA; 1.93% for SG; 2.18% for RYGB and 5.23% for BPD. The incidence of bleeding was 0.44% in AGB; 1.29% in SG; 0.81% in RYGB and 2.09% in BPD. The rate of DM2 resolved was 46.80% in AGB, 79.38% in SG, 79.86% in RYGB and 90.78% in BPD. The rate of dyslipidemia, apnea and hypertension resolved showed no statistical differences between the techniques. Conclusion: The AGB has the lowest morbidity and mortality and it is the worst in EWL and resolution of type 2 diabetes. The SG has low morbidity and mortality, good resolution of comorbidities and EWL lower than in RYGB and BPD. The RYGB has higher morbidity and mortality than AGB, good resolution of comorbidities and EWL similar to BPD. The BPD is the worst in mortality and bleeding and better in EWL and resolution of comorbidities.

ABSTRACT

OBJECTIVE: Colorectal cancer is one of the most frequent types of malignant neoplasms. Age is a risk factor for this disease, with 75% of cases diagnosed in patients older than 65 years. Complications such as obstruction, hemorrhage, and perforation are present in more than one-third of cases and require emergency treatment. We aim to analyze the profile of elderly patients undergoing surgery for complicated colorectal cancer, and to evaluate factors related to worse short-term prognosis. METHODS: A retrospective analysis of patients who underwent emergency surgical treatment for complicated colorectal cancer was performed. Demographics, clinical, radiological and histological data were collected. RESULTS: Sixty-seven patients were analyzed. The median age was 72 years, and almost half (46%) of the patients were female. Obstruction was the most prevalent complication at initial presentation (72%). The most common sites of neoplasia were the left and sigmoid colon in 22 patients (32.8%), and the right colon in 17 patients (25.4%). Resection was performed in 88% of cases, followed by primary anastomosis in almost half. The most frequent clinical stages were II (48%) and III (22%). Forty-three patients (65.7%) had some form of postoperative complication. Clavien-Dindo grades 1, 2, and 4, were the most frequent. Complete oncologic resection was observed in 80% of the cases. The thirty-day mortality rate was 10.4%. Advanced age was associated with worse morbidity and mortality. CONCLUSION: Elderly patients with complicated colorectal cancer undergoing emergency surgery have high morbidity and mortality rates. Advanced age is significantly associated with worse outcomes.

ABSTRACT

Abstract Objective: To evaluate the predictive value of mean perfusion pressure (mPP) in the development of acute kidney injury (AKIN) after transcatheter aortic valve implantation (TAVI). Methods: One hundred and forty seven consecutive patients with aortic stenosis (AS) were evaluated for this study and 133 of them were included. Mean arterial pressure (mAP) and central venous pressure (CVP) were used to calculate mPP before TAVI procedure (mPP = mAP-CVP). The occurrence of AKIN was evaluated with AKIN classification according to the Valve Academic Research Consortium-2 recommendations. The patients were divided into two groups according to the receiver operating characteristic (ROC) analysis of their mPP levels (high-risk group and low-risk group). Results: The AKIN prevalence was 22.6% in this study population. Baseline serum creatinine level, glomerular filtration rate, amount of contrast medium, and the level of mPP were determined as predictive factors for the development of AKIN. Conclusion: The occurrence of AKIN is associated with increased morbidity and mortality rates in patients with TAVI. In addition to the amount of contrast medium and basal kidney functions, our study showed that lower mPP was strongly associated with development of AKIN after TAVI.

ABSTRACT

RESUMEN Introducción: En la actualidad, la diversidad de criterios relacionados con las reintervenciones quirúrgicas constituyen un verdadero problema científico, por cuanto, resulta de gran importancia profundizar en torno a los principales aspectos cognoscitivos relacionados con este tema a fin de elevar la calidad asistencial y, con esa premisa, el índice de supervivencia, sobre todo en la población envejecida como grupo vulnerable. Objetivos: Identificar los factores que permitan reconocer las condiciones modificables que disminuyan las complicaciones y fallecimientos de los enfermos tributarios de un nuevo tratamiento quirúrgico para salir adelante y sobrevivir. Métodos: Revisión digital de publicaciones actualizadas en español e inglés en bases de datos: Google, Redalyc, PubMed, Medline, Lilacs, Elsevier. Resultados: Las complicaciones posquirúrgicas y las que requieren una reintervención en particular son de origen multifactorial. No existe una definición y una clasificación estandarizada de las complicaciones posquirúrgicas para notificarlas. Las más utilizadas son las objetivas de Clavien Dindo y Accordeon, basadas en la estratificación del tratamiento requerido, el riesgo y gravedad. Conclusiones: A pesar de que el gran avance tecnológico actual en los métodos diagnósticos y terapéuticos ha permitido que los pacientes con complicaciones posquirúrgicas sean reintervenidos con mayor seguridad, la morbilidad y la mortalidad a causa de estas continúan elevadas(AU)


ABSTRACT Introduction: Nowadays, the diverse criteria related to surgical reinterventions are a real scientific problem since it is very important to delve into the main cognitive aspects associated to this topic in order to raise the quality of medical assistance and thus the survival index in the old population as a vulnerable group. Objectives: To identify the factors that allow recognizing the modifiable conditions that lead to less complications and deaths of patients undergoing a new surgical treatment. Methods: Search of updated publications in English and Spanish made in Goggle, Redalyc, PubMed, Medline, Lilacs and Elsevier databases. Results: The postsurgical complications and those requiring surgical reintervention in particular are of multifactoral origin. There is neither one single definition nor one standardized classification of the postsurgical complications to notify them. The most used objective classifications are Claven Dindo and Accordeon, based on the stratification of the required treatment, the risk and the severity. Conclusions: In spite of the fact that the great technological advances in the diagnostic and therapeutic methods have allowed the reoperation of complicated patients with higher margin of safety, morbidity and mortality caused by such complications are still high(AU)

ABSTRACT

Abstract Introduction: The aim of this study was to determine the outcomes of patients developing ischemic stroke after coronary artery bypass grafting (CABG). Methods: From March 2012 to January 2017, 5380 consecutive patients undergoing elective coronary surgery were analyzed. Ninety-five patients who developed ischemic strokes after on-pump coronary surgery were included in the study, retrospectively. The cohort was divided into four subgroups [total anterior circulation infarction (TACI), partial anterior circulation infarction (PACI), posterior circulation infarction (POCI), and lacunar infarction (LACI)] according to the Oxfordshire Community Stroke Project (OCSP) classification. The primary endpoints were in-hospital mortality, total mortality, and survival analysis over an average of 30 months of follow-up. The secondary endpoints were the extent of disability and dependency according to modified Rankin Scale (mRS). Results: The incidence of stroke was 1.76% (n=95). The median age was 62.03±10.06 years and 68 (71.6%) patients were male. The groups were as follows: TACI (n=17, 17.9%), PACI (n=47, 49.5%), POCI (n=20, 21.1%), and LACI (n=11, 11.6%). Twenty-eight (29.5%) patients died in hospital and 34 (35.8%) deaths occurred. The overall mortality rate of the TACI group was significantly higher than that of the LACI group (64.7% vs. 27.3%, P=0.041). The mean mRS score of the TACI group was significantly higher than that of the other groups (P=0.003). Conclusion: Patients in the TACI group had higher in-hospital and cumulative mortality rates and higher mRS scores. We believe that use of the OCSP classification and the mRS may render it possible to predict the outcomes of stroke after coronary surgery.

ABSTRACT

Abstract Introduction: Among patients undergoing cardiac surgery, the occurrence of acute renal injury appears to be associated with worse prognosis and increased mortality. The objective of this study was to evaluate risk factors and the impact this complication on mortality and survival after cardiac surgery among patients without chronic kidney disease. Methods: In this retrospective study, we reviewed the medical records of 142 patients who underwent elective coronary artery bypass grafting, valve replacement (single or multiple), or both (simultaneously) at a tertiary care hospital. Results: Among the 142 patients evaluated, the mean age was 58.28±13.87 years and 80 (56.33%) were female. The postoperative incidence of acute renal injury was 43.66%. Univariate analysis between the groups with and without acute renal injury revealed no significant differences, whereas multivariate analysis showed that risk factors for acute renal injury included valve replacement (OR=4.7, P=0.002, 95% CI=1.76-12.62, age (OR=1.044, P=0.012, 95% CI=1.01-1.07), previous cardiac surgery (OR=36.1, P=0.015, 95% CI=1.99-653.85), postoperative use of the vasoactive drug norepinephrine (OR=3.32, P=0.013, 95% CI=1.29-8.58) and dobutamine (OR=5.3, P=0.019, 95% CI=1.32-21.64). In our sample, there were 30 deaths, of which 25 had acute kidney injury. Survival was also lower among the patients with this complication, especially those who had required hemodialysis (OR=2.60, P<0.001, 95% CI=1.01-6.70) or had previously undergone cardiac surgery (OR=3.68, P<0.001, 95% CI=1.09-12.37). Conclusion: Our findings underscore the importance of identifying risk factors for developing acute renal injury after cardiac surgery, which can further the development of effective renoprotective strategies.

ABSTRACT

Abstract Objective: The aims of this study were to identify the risk factors associated with acute kidney injury (AKI) after isolated surgical revascularization with cardiopulmonary bypass and to develop a model to predict the appearance of postoperative AKI. Methods: A total of 435 adult patients who underwent primary isolated coronary artery bypass graft (CABG) surgery, from 2012 to 2016, in the Clinic University Hospital of Valladolid (Spain) were enrolled. AKI was defined according to the risk, injury, failure, loss, and end-stage (RIFLE) criteria. Data were collected from hospital electronic medical records. Multiple logistic regression analysis was used to identify risk factors. Results: The prevalence of AKI was 12.4%. Multivariate analysis identified age (odds ratio [OR], 1.056; 95% confidence interval [CI], 1.016-1.098; P=0.005), hypertension (OR, 3.078; 95% CI, 1.151-8.230; P=0.018), low ejection fraction (EF) (OR, 6.785; 95% CI, 2.080-22.135; P=0.001), estimated glomerular filtration rate (eGFR) (OR, 1.017; 95% CI, 1.005-1.028; P=0.014), EuroSCORE II (OR, 1.049; 95% CI, 1.004-1.096; P=0.033), and no intake of calcium-channel blockers (CCB) (OR, 4.892; 95% CI, 1.496-16.025; P=0.022) as risk factors for AKI. These risk factors were included in a model to predict postoperative AKI with an area under a receiver operating characteristic curve of 0.783±0.036 (95% CI, 0.713-0.854; P<0.0001). Conclusion: Age, hypertension, low EF, eGFR, EuroSCORE II, and no intake of CCB were independent risk factors for postoperative AKI. These factors provide an easy and accurate model to predict postoperative AKI in patients undergoing cardiac surgery.

ABSTRACT

Abstract Objective: Acute kidney injury (AKI) is a frequent postoperative complication after cardiovascular surgery. It has been described as a predictor of decreased survival rates, but how dialysis decreases survival when initiated on the postoperative period has yet to be determined. To analyze the survival of patients who presented postoperative AKI requiring dialysis up to 30 days after cardiovascular surgery and its risk factors is the aim of this study. Methods: Of the 5,189 cardiovascular surgeries performed in a 4-year period, 157 patients developed AKI requiring dialysis in the postoperative period. The Kaplan-Meier survival curve and log-rank test were used in the statistical analysis to compare the curves of categorical variables. P-value< 0.05 was considered significant. Results: Patient average survival was 546 days and mortality was 70.7%. The need for dialysis on the postoperative period decreased late survival. Risk factors for decreased survival included age (P<0.001) and postoperative complications (P<0.0003). Conclusion: The average survival was approximately one year among dialytic patients. Age and postoperative complications were risk factors that determined decreased survival.
