Dissecção espontânea da artéria coronária em gestação gemelar no terceiro trimestre: relato de caso / Spontaneous coronary artery dissection in a twin pregnancy in the third trimester: a case report

O infarto agudo do miocárdio no período gravídico-puerperal é uma condição rara em que a principal causa é a dissecção espontânea da artéria coronária. É um evento comumente subdiagnosticado, com pouca literatura disponível e elevado índice de morbimortalidade. Esse relato descreve o caso de uma gestante de 36 semanas de gravidez gemelar, monocoriônica-diamniótica, com infarto agudo do miocárdio secundário à dissecção espontânea da artéria coronária. As equipes de cirurgia cardíaca e obstetrícia optaram pela realização de parto cesariano e histerectomia subtotal, seguido da revascularização da artéria mamária descendente anterior. Discutem-se as orientações adotadas na dissecção espontânea da artéria coronária, bem como a abordagem terapêutica e a conduta obstétrica, quando essa condição ocorre durante a gravidez.(AU)

Acute myocardial infarction in the pregnancy-puerperal period is a rare condition the main cause of which is the spontaneous coronary artery dissection. A commonly underdiagnosed event with little available literature and a high rate of morbidity and mortality. This case reports a 36-week pregnant woman of mono-chorionic-diamniotic pregnancy who had a myocardial infarction secondary to a spontaneous coronary artery dissection. In a joint discussion between the team of cardiac surgery and obstetrics, it was decided to perform a cesarean delivery and subtotal hysterectomy followed by revascularization of the mammary anterior descendant. It discusses the conducts to be adopted in a case of spontaneous coronary artery dissection as well as therapeutic approaches and obstetric conducts to be taken in a case of dissection during pregnancy.(AU)

Endoscopic and Oncologic Outcomes of Endoscopic Resection for Superficial Esophageal Neoplasm

BACKGROUND/AIMS: Endoscopic resection (ER) of superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ER for SEN to determine its feasibility and effectiveness. METHODS: Subjects who underwent ER for SEN at Asan Medical Center between December 1996 and December 2010 were eligible. The clinical features of patients and tumors, histopathological characteristics, adverse events, ER results and survival were investigated. RESULTS: A total of 129 patients underwent ER for 147 SENs. En bloc resection (EnR) was performed in 118 lesions (80.3%). Complete resection (CR) was accomplished in 128 lesions (86.5%), and curative resection (CuR) was performed in 118 lesions (79.7%). The EnR, CR, and CuR rates were significantly greater in the endoscopic submucosal dissection group when compared to those in the endoscopic resection group. Adverse events occurred in 22 patients (17.1%), including bleeding (n=2, 1.6%), perforation (n=12, 9.3%), and stricture (n=8, 6.2%). Local tumor recurrence occurred in 2.0% of patients during a median follow-up of 34.8 months. The 5-year overall and disease-specific survival rates were 94.0% and 97.5%, respectively. CONCLUSIONS: ER is a feasible and effective method for the treatment of SEN as indicated by favorable clinical outcomes.

Efficacy and Safety of Endoscopic Resection Therapies for Rectal Carcinoid Tumors: A Meta-Analysis

PURPOSE: Several endoscopic resection therapies have been applied for the treatment of rectal carcinoid tumors. However, there is currently no consensus regarding the optimal strategy. We performed a meta-analysis to compare the efficacy and safety of endoscopic mucosal resection (EMR) or modified EMR (m-EMR) versus endoscopic submucosal dissection (ESD) for the treatment of rectal carcinoid tumors. MATERIALS AND METHODS: PubMed, Web of Science, Medline, Embase and CNKI were searched up to the end of January 2014 in order to identify all studies on the effects of EMR (or m-EMR) and ESD on rectal carcinoid tumors. RESULTS: A total of fourteen studies involving 782 patients were included. The pooled data suggested a significantly higher rate of pathological complete resection among patients treated with ESD or m-EMR than those treated with EMR [odds ratio (OR)=0.42, 95% confidence interval (CI): 0.25-0.71; OR=0.10, 95% CI: 0.03-0.33, respectively], while there was no significant difference between the m-EMR group and ESD group (OR=1.19, 95% CI: 0.49-2.86); The procedure time of ESD was longer than EMR or m-EMR groups [mean differences (MD)=-11.29, 95% CI: -14.19 - -8.38, MD= -10.90, 95% CI: -18.69 - -3.11, respectively], but it was insignificance between the EMR and m-EMR groups. No significant differences were detected among the treatment groups with regard to complications or recurrence. CONCLUSION: The results of this meta-analysis suggest that treatment of rectal carcinoid tumors with ESD or m-EMR is superior to EMR, and the efficacy of m-EMR is equivalence to ESD treatment. However, more well-designed studies are needed to confirm these findings.

Ritidoplastia mini-invasiva, um procedimento efetivo através de pequenas incisões / Mini-invasive facelift, an effective procedure through small incisions

Introdução: Os procedimentos aplicados nos problemas de envelhecimento facial devem ficar restritos aos tecidos brandos e às relações com o volume prévio do esqueleto. Eles podem ser realizados mediante diversas técnicas: dissecção ampla e aberta, endoscópica e mini-invasiva. O objetivo é apresentar nossa concepção de ritidoplastias mini-invasivas e ritidoplastias completas através de mini-incisões, após 18 anos de experiência. Métodos: A ritidoplastia mini-invasiva é realizada através de mini-incisões localizadas na linha do cabelo da região frontal, região temporal, na fossa triangular da orelha, no sulco submentoniano e nas pálpebras. Ampla dissecção é realizada para liberar a fáscia parietal do arco zigomático para elevar em continuidade com o SMAS e o platisma num único plano. Essas estruturas são seletivamente fixadas em posições mais elevadas, restaurando a posição dos tecidos brandos e o contorno da face. Resultados: Nossa experiência se apoia em 672 pacientes, operados durante 19 anos, com mínimo de complicações a serem registradas, tendo sido evitadas as incisões pré-auriculares em 89% dos pacientes. Estão registrados os detalhes e táticas de como realizar cirurgias com segurança e a qualidade dos resultados. Conclusões: Diferentes procedimentos são descritos para mostrar como realizamos as ritidoplastias com minivias de acesso, de acordo com as regiões tratadas e sem cicatrizes pré-auriculares em 89% dos casos operados.

Introduction: A restoring procedure of the ageing process of the face should consider the conditions of the soft tissues and the relationship between them and the existing skeletal volume. This could be done through different approaches: open, endoscopic or mini-invasive. To present our concept of mini-invasive facelift, a full facelift through minimal incisions, product of eighteen years of experience. Methods: The mini-invasive facelift is done through minimal incisions located on the frontal hairline, temporal area, triangular fossae of the auricle, submentalis sulcus and eyelids. A wide dissection is performed to liberate the parieto-temporal fascia from the zigomatic arch, to pull it up in continuity with the SMAS and the platysma as one continuous layer or composite flap. These structures are selectively fixed to a higher position restoring the location of the soft tissues and the contour of the face. Results: We have done this procedure to 672 patients, along 19 years, with minimal complications (described also), and avoiding the pre-auricular incisions in 89% of our patients. In this paper details and tips to perform this procedure in a safer way and to get the most natural results are presented. Conclusions: Different approaches are described to perform a face lift with specific mini access views according to the regions to be treated , without periauricular scar round 89% of the operated cases.

The Need for Second-Look Endoscopy to Prevent Delayed Bleeding after Endoscopic Submucosal Dissection for Gastric Neoplasms: A Prospective Randomized Trial

BACKGROUND/AIMS: Many authors recommend performing a second-look endoscopy (SLE) to reduce the frequency of delayed bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasms, but these recommendations have been made despite a lack of reliable evidence supporting the effectiveness of SLE. METHODS: From January 2012 to May 2013, we investigated 441 gastric neoplasms treated by ESD to assess the risk factors for delayed bleeding. Delayed bleeding occurred in four of these lesions within 1 postoperation day. Therefore, we enrolled the patients with the remaining 437 lesions to determine the utility of SLE performed on the morning of postoperative day 2. All lesions were randomly assigned to SLE (220 lesions) groups or non-SLE (217 lesions) groups. RESULTS: Delayed bleeding occurred in 18 lesions (4.1%). A large tumor size (>20 mm) was the only independent risk factor for delayed bleeding (p=0.007). The chance of delayed bleeding was not significantly different between the patients receiving a SLE (eight cases) and those patients not receiving a SLE (six cases, p=0.787). Furthermore, SLE for lesions with a large tumor size did not significantly decrease delayed bleeding (p=0.670). CONCLUSIONS: SLE had little or no influence on the prevention of delayed bleeding, irrespective of the risk factors.

Relata-se o caso de uma mulher jovem, previamente hígida, com infarto agudo do miocárdio abordado inicialmente com o uso de trombolítico. Foi submetida a cateterismo cardíaco que evidenciou imagem compatível com longo trecho de dissecção em coronária direita, tratada através de angioplastia, com implante de dois stents convencionais e restauração completa do fluxo do vaso, evoluindo bem sob o ponto de vista.

This case study presents a previously healthy young woman with acute myocardial infarction, initially treatedwith thrombolytic therapy, and transferred to our institution. She underwent cardiac catheterization thatshowed an image compatible with a long stretch of dissection in the right coronary artery, treated through angioplasty, with two bare metal stents implanted andcomplete restoration of vessel flow, progressing well from the clinical standpoint.

A Case of Acute Myocardial Infarction Occurred Immediately after Endoscopic Submucosal Dissection / 대한소화기학회지

Endoscopic methods such as endoscopic mucosal resection or endoscopic submucosal dissection (ESD) have been increasingly used for the treatment of gastric adenoma and early gastric cancer. Especially, ESD is very useful since it allows en bloc resection of large lesions. Bleeding and perforation are well known as common complications after ESD. However, there is no report of acute myocardial infarction associated with ESD. We report a case of acute myocardial infarction which was detected immediately after ESD.

Abordagem supraclavicular da artéria subclávia direita para estabelecimento de circulação extracorpórea nas doenças da aorta / Boarding to supraclavicular of the right subcla artery for extracorporeal establishment of circulation in disease of aorta

OBJETIVO: Estabelecer a circulação extracorpórea através de canulação da artéria subclávia direita por meio de incisão supraclavicular. MÉTODO: Foram estudados, no período de outubro de 2001 a março de 2002, quatro pacientes com diagnóstico de dissecção aguda de aorta tipo A de Stanford, sendo realizada em todos os casos canulação da artéria subclávia direita por via supraclavicular e realização de perfusão cerebral anterógrada durante o período de parada circulatória total. RESULTADOS: A artéria subclávia direita foi canulada diretamente e não houve nenhuma complicação neurovascular relacionada ao procedimento. A circulação extracorpórea foi mantida com fluxo adequado durante toda a operação. Houve 1 óbito hospitalar, não relacionado ao procedimento. DISCUSSÃO: Um dos passos mais importantes na melhora dos resultados operatórios é a perfusão sistêmica anterógrada, realizada através do sistema arterial e a subclávia para isso permite a perfusão da luz verdadeira. A abordagem supraclavicular nos proporciona um campo operatório adequado e facilidade para a realização da perfusão cerebral anterógrada que também é importante neste arsenal para uma redução da mortalidade operatória. CONCLUSÃO: A incisão supraclavicular nos proporciona um acesso factível com boa exposição da artéria subclávia direita em uma região em que ela apresenta um bom calibre e com poucas estruturas adjacentes que poderiam ser lesadas. Além disso, possibilita a canulação de forma direta e com boa posição da cânula arterial

Exsanguinotransfusión en hiperbilirrubinemia neonatal: complicaciones y letalidad / Exchange transfusion in neonatal hyperbilirubinaemia: complications and lethality

En el presente trabajo se evalúan las complicaciones y mortalidad que se presentaron en 320 exsanguinotransfusiones (ET) practicadas. El procedimiento se realizó en el 83% de los casos a través del cateterismo de vasos umbilicales y en el resto por disección quirúrgica de un vaso central o umbilical.Las complicaciones inmediatas más frecuentes fueron sangrado (2.5%). arritmia cardiaca (1.6%) y apnea prolongada (1.2%). De las tardías la más frecuente fue onfalitis (3.4%), seguida de enterocolitis necrosante (1.2%). En el 98.1% de los casos se logró finalizar la ET. Su letalidad global fue de 1.8%. la cual se observó en seis pacientes pretérmino con pesos menores de 2000 g y padecimientos asociados graves. La mortalidad fue simular a la de trabajos previos, habiendo participado en la realización de los procedimientos el personal médico residente. La letalidad por ET disminuyó en el mismo Servicio, lo cual es una tenedencia general y se atribuye a la mayor comprensión de la disiopatologia neonatal y el mejor cuidado de los recién nacido gravemente enfermos. Muchas de las complicaciones son previsibles
