Is there an Electro-Angiographic Correlation in RD Infarction?

Introduction: Coronary angiography is the examination of choice in the evaluation of coronary anatomy during acute myocardial infarction, particularly of the right ventricle (RV), whose diagnosis remains difficult. The electrocardiogram reflects the pathophysiology of myocardial ischemia, thus allowing prediction of the culprit lesion. Objective: To investigate the correlation between electrical and coronary data and to judge the reproducibility of the electrocardiogram in identifying the culprit lesion in RV infarction. Materials and Methods: Retrospective study of patients hospitalized in the Cardiology Department of the Mohammed VI University Hospital in Marrakech over a period of 24 months for MDI extended to the RV. Results: During the study period, 120 patients were hospitalized for MI with RV extension. Inferior MI represented 70% of all cases of infarction extended to the RV. It is represented electrically by isolated ST-segment elevation in V3R found in 76%, as well as in association with an elevation in V4R in 45% of cases. Conduction disorders were noted in 38% of cases, presented essentially by first degree atrioventricular block, without any electrical specificity. Coronary angiography was performed in 91% of patients, half of whom underwent coronary angioplasty. A bi-truncular involvement (RC + VIA) was found in 40% of cases, the middle DC is the culprit lesion in almost half of the cases of VD infarction. The presence of an ST elevation in the isolated V3R shunt is a specific criterion of right middle coronary involvement, found in 48% of patients. Conclusion: The ECG remains an essential tool in the early prediction of the artery responsible for the infarction. Because of its complementary nature, the combination of ECG and coronary angiography is essential for a better evaluation of acute myocardial infarction.

Predictors and prediction scores of shunt-dependent hydrocephalus in patients with aneurismal subarachnoid hemorrhage / 国际脑血管病杂志

Shunt-dependent hydrocephalus (SDHC) is a common and serious complication of aneurismal subarachnoid hemorrhage (aSAH). The incidence of SDHC after aSAH was 9%-36%, and it is associated with the poor outcome of patients. This article reviews the predictors and prediction scores of SDHC after aSAH.

Effect of Intra Cardiac Shunts on Left Ventricular Systolic Function: A Speckle Tracking Study

Background: The left ventricular (LV) chamber size and its systolic function is the most common and quickest assessment made by echocardiography, either in the intra operative or intensive care setting, being the pressure generator for the blood supply to the body .Congenital cardiac defects come in two main types: atrial and ventricular septal defects (ASD/VSD). Regression or spontaneous closure may be the natural course of minor septal defects. Aim and Objectives: The aim of the study was to assess the feasibility of speckle tracking echocardiography in estimation of left ventricular systolic function in congenital shunt lesions (ASD, VSD and PDA). Subjects and Methods: This study was done in Tanta University Hospital including 270 patients. The patients were divided into four groups: ASD patients, VSD patients, PDA patients and control subjects. Results: It showed statistically significant difference between ASD, PDA and control group. The difference between the PDA group and the control group was statistically significant. There was a statistically significant difference between the ASD group and the control group in terms of EF percent, FS percent, and ESV ROC curve for Validity of GLS to predict LV systolic dysfunction in PDA Group. Sensitivity was 68 and sensitivity was 80. Conclusion: It was determined that Speckle-tracking echocardiography offers an additional non-invasive method for evaluating patients' left ventricular function. With congenital shunt lesions.

Outcomes of Ahmed glaucoma valve and transscleral cyclophotocoagulation in neovascular glaucoma

Purpose: To determine the outcomes of Ahmed glaucoma valve (AGV) and transscleral diode cyclophotocoagulation (CPC) in neovascular glaucoma (NVG). Methods: This was a single?center retrospective comparative case series involving chart review of consecutive patients who underwent AGV or CPC for treatment of NVG and had ?6 months of follow?up. Surgical failure at 6 months, defined as an IOP of >21 or <6 mm Hg with hypotony maculopathy after 1 month, progression to no light perception (NLP) vision, glaucoma reoperation, or removal of AGV were the main outcome measures. Results: In total, 121 eyes of 121 patients were included (70 AGV and 51 CPC). Baseline demographics, visual acuity (VA), and intraocular pressure (IOP) were comparable between groups. At 6 months, failure was significantly higher in the CPC group than in the AGV group (43.1% vs. 17.1%, P = 0.020). Both groups had similar IOP and medication number at 6 months, but VA was significantly lower in the CPC group compared to the AGV group (2.4 � 0.8 vs. 1.9 � 1.0, P = 0.017). More CPC eyes required reoperation for glaucoma than AGV eyes (11.8% vs. 1.4%, P = 0.041). Multivariate regression analysis identified higher preoperative IOP (P = 0.001) and CPC surgery (P = 0.004) as independent predictors of surgical failure at 6 months. Age, sex, race, NVG etiology, bilaterality of the underlying retinal pathology, perioperative retina treatment, and prior or combined vitrectomy were not significant. Conclusion: AGV and CPC had comparable IOP and medication reduction in NVG eyes at 6 months. CPC was more frequently associated with failure, reoperation for glaucoma, and worse visual outcomes. High preoperative IOP and CPC surgery independently predicted surgical failure.

Abstract Hydrocephalus is a frequent health problem in pediatrics, particularly during the first month of life. The incidence in Latin America is one of the highest in the world. In Colombia there are no representative data. Recent findings related to the dynamics of cerebrospinal fluid allowed proposals of new models on the pathophysiology of hydrocephalus that, along with new findings on MRI, have led to a better understanding of the disease. The aim of this work is to review the information available in the literature about the progress in the pathophysiology of the disease and neuroimaging findings, in addition to conducting a brief review on the role of these in the diagnosis and follow-up of patients. A bibliographic review with MeSH terms was carried out in PUBMED, OVID and SCOPUS databases, with articles published in the last 6 years. 30 articles that dealt with the theme in a comprehensive way were included. New findings described as the glymphatic system and the role of AQP4, along with advances in neuroimaging, especially MRI, have helped to better understand hydrocephalus, supporting the development of a new model of cerebrospinal fluid dynamics, and based on it, different explanations regarding its pathophysiology.

Historical Clinical Outcomes of Children with Myelomeningocele Meeting the Criteria for Fetal Surgery: A Retrospective Cohort Survey of Brazilian Patients / Resultados clínicos históricos de crianças com mielomeningocele com critérios para cirurgia fetal: Um estudo de coorte retrospectivo de pacientes brasileiros

Abstract Objective To analyze the historical clinical outcomes of children with myelomeningocele (MMC) meeting the criteria for fetal surgery, but who underwent postnatal primary repair. Methods Data from children undergoing postnatal MMC repair between January 1995 and January 2015 were collected from the Neurosurgery Outpatient Clinic's medical records. Children were included if they had ≥1 year of postoperative follow-up andmet the criteria for fetal surgery. The children's data were then stratified according to whether they received a shunt or not. The primary outcome was mortality, and secondary outcomes were educational delays, hospitalization, recurrent urinary tract infections (UTIs), and renal failure. Results Over the 20-year period, 231 children with MMC were followed up. Based on clinical data recorded at the time of birth, 165 (71.4%) qualify of fetal surgery. Of the 165 patients, 136 (82.4%) underwent shunt placement. The mortality rate was 5.1% in the group with shunt and 0% in the group without, relative risk (RR) 3.28 (95% confidence interval, 95% CI, 0.19-55.9). The statistically significant RRs for adverse outcomes in the shunted group were 1.86 (95% CI, 1.01-3.44) for UTI, 30 (95% CI, 1.01-537) for renal failure, and 1.77 (95% CI, 1.09-2.87) for hospitalizations. Conclusion Children with MMC qualifying for fetal surgery who underwent shunt placement were more likely to have recurrent UTIs, develop renal failure, and be hospitalized. Since approximately half of the shunt procedures could be avoided by fetal surgery, there is a clinical benefit and a possible financial benefit to the implementation of this technology in our setting.

Resumo Objetivo Analisar os resultados clínicos históricos de crianças commielomeningocele (MMC) com critérios para cirurgia fetal,mas que foram submetidas a cirurgia pós-natal. Métodos Dados de crianças submetidas à correção deMMCpós-natal entre janeiro de 1995 e janeiro de 2015 foram coletados nos prontuários do Ambulatório de Neurocirurgia. Foram incluídas crianças se tivessem ≥ 1 ano de acompanhamento pósoperatório e atendessem os critérios para cirurgia fetal. As informações dessas crianças foram então estratificadas de acordo com se receberam ou não derivação do líquido cefalorraquidiano. O desfecho primário foi a mortalidade e os desfechos secundários foram atrasos educacionais, hospitalização, infecções recorrentes do trato urinário einsuficiência renal. Resultados Durante o período de 20 anos, 231 crianças com MMC foram acompanhadas. Com base nos dados clínicos registrados no momento do nascimento, 165 (71,4%) atendiam critérios para a cirurgia fetal. Dos 165 pacientes, 136 (82,4%) foram submetidos à colocação de derivação do líquido cefalorraquidiano. A taxa de mortalidade foi de 5,1% no grupo com derivação do líquido cefalorraquidiano e 0% no grupo sem risco relativo (RR) 3,28 (intervalo de confiança 95%, IC 95%, 0,19-55,9). Os RRs estatisticamente significativos para resultados adversos no grupo com derivação do líquido cefalorraquidiano foram 1,86 (IC 95%, 1,01-3,44) para infecção do trato urinário, 30 (IC 95%, 1,01-537) para insuficiência renal e 1,77 (IC 95%, 1,09-2,87) para hospitalizações. Conclusão Crianças com MMC com critérios para cirurgia fetal submetidas à colocação de derivação do líquido cefalorraquidiano eram mais propensas a ter infecções recorrentes do trato urinário, desenvolver insuficiência renal e serem hospitalizadas. Como aproximadamente metade dos procedimentos de derivação poderiam ser evitados por cirurgia fetal, há um benefício clínico e um possível benefício financeiro com a implementação dessa tecnologia em nosso meio.

The therapeutic effects of endoscopic ultrasound-guided coil embolization for gastric varices (with video) / 中华消化内镜杂志

Objective:To investigate the safety and efficacy of endoscopic ultrasound-guided coil embolization for gastric varices.Methods:Patients with portal hypertension who received endoscopic ultrasound-guided coil embolization for the prophylaxis of gastric variceal bleeding between November 2016 and August 2020 at Zhongshan Hospital, Fudan University were included in the study. The primary evaluation index was the post-operative loss of blood flow in gastric varices, and the secondary indices included the safety of coil embolization, rebleeding rate, portal vein thrombosis changes and patient survival.Results:A total of 13 patients with isolated gastric varices and portal systemic shunt were enrolled, including 6 males and 7 females with the median age of 58 years. The median maximum diameter of the target vessel was 40 mm and the median number of coils used was 2.7. All puncture sites were in the lower part of the esophagus near the cardia, and no active bleeding occurred after deployment of coils. Flow in the gastric varices were confirmed absent by Doppler imaging. In a median follow-up period of 403 days, 2 patients had rebleeding, with the one-year rebleeding rate of 9.1%.Two patients developed portal venous thrombosis after the operation. Two patients died, and the one-year survival rate was 90.0%.Conclusion:Endoscopic ultrasound-guided coil embolization might be an effective option for the treatment of isolated gastric varices with portal systemic shunts.

A retrospective study of endoscopic ultrasound-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices / 中华消化内镜杂志

Objective:To evaluate the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt.Methods:Data of 24 patients with gastric fundal varices with large spontaneous shunt (the smallest diameter was 5-15 mm) treated by EUS-guided coil embolization combined with endoscopic cyanoacrylate injection in Renmin Hospital of Wuhan University from December 2016 to December 2020 were retrospectively analyzed. The short-term efficacy (the rates of technical success, five-day rebleeding and six-week mortality) and long-term efficacy (the rates of one-year rebleeding, one-year mortality and three-year mortality) and safety (ectopic embolism) were evaluated.Results:The technical success rate was 91.7% (22/24), and the five-day rebleeding rate was 0 (0/22). Computed tomography angiography of portal vein reexamined 2 days after the treatment showed embolism of splenic vein in 1 patient (4.5%). The median follow-up time was 14.9 months (ranging 1.0-48.6 months) and 2 patients were lost during follow-up. The six-week mortality was 0 (0/20), and the one-year rebleeding rate was 35.0% (7/20). Among 12 patients who underwent endoscopy in the follow-up, 5 had aggravation of esophageal varices, and 5 had aggravation of portal hypertension gastropathy. The one-year and three-year mortalities were 5.0% (1/20) and 20.0% (4/20), respectively, neither of which was related to such events as bleeding or ectopic embolism.Conclusion:EUS-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt is effective and safe in short term, with a low rate of ectopic embolism. Long-term efficacy and safety need to be further confirmed.

Hepatic encephalopathy: Modern views on the treatment of abnormal portosystemic shunt / 临床肝胆病杂志

Hepatic encephalopathy (HE) is a type of serious brain dysfunction caused by acute or chronic liver failure or portosystemic shunt, with the clinical manifestation of neuropsychiatric abnormalities. The incidence rate of HE is 16%-21% in patients with liver cirrhosis. Spontaneous portosystemic shunt (SPSS) is one of the major pathogenesis of HE and is observed in 60%-70% of the patients with liver cirrhosis, and the size, number, and location of SPSS are directly associated with the development of HE. The development and wide application of imaging technology help to achieve a more convenient and accurate diagnosis of SPSS. Although interventional vascular embolization of SPSS has achieved a satisfactory clinical outcome in some cirrhotic patients with HE, high-quality clinical studies are still needed.

Relationships between intracranial compartment volumes and clinical symptoms in patients with idiopathic normal pressure hydrocephalus before and after cerebrospinal fluid shunt surgery / 中华老年医学杂志

Objective To investigate the relationships of intracranial compartment volumes with the severity of clinical symptoms before surgery,and the degree of symptom improvement one year after cerebrospinal fluid(CSF)shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH).Methods Twenty-one patients meeting the diagnosis criteria of international guidelines of iNPH and undergoing CSF shunt surgery in Department of Neurosurgery in our hospital from 2016 to 2017 were included.All patients underwent brain MRI measurement before surgery,and were evaluated by using 3-meter timed up and go test(TUG),minimum mental state examination(MMSE),idiopathic normal pressure hydrocephalus grading scale (iNPHGS) and modified Rankin scale (mRS) before and one year after CSF shunt procedures.The ventricular volume,brain volume,pericerebral CSF volume,total intracranial volume and Evans' index were measured in the pre-operative imaging of the brain.The following four pre-operative intracranial compartment volumes were calculated:the relative ventricular volume,brain volume ratio,pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume.Results The scores of gait,cognitive function and urinary function were improved after surgery in iNPH patients (all P ＜ 0.05).There were no significant difference in the correlation of intracranial compartment volumes(the relative ventricular volume,brain volume ratio,pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index with the severity of clinical symptoms including gait,cognitive function and urinary function before surgery,and with the degree of symptom improvement one year after surgery in iNPH patients (all P ＞ 0.05).There was no significant difference in intracranial compartment volumes between patients having improvement in mRS,TUG,MMSE and iNPHGS and patients having no improvement one year after surgery in iNPH patients(all P＞0.05).Conclusions Patients with iNPH can benefit from CSF shunt surgery and have improvements of clinical symptoms including gait,cognitive function and urinary function.Preoperative intracranial compartment volumes(the relative ventricular volume,brain volume ratio,pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index have no correlations with the severity of clinical symptoms before surgery,and have no correlations with the degree of symptom improvement one year after surgery in iNPH patients.For this reason,preoperative intracranial compartment volumes and Evans' index cannot be used to predict whether or not CSF shunt surgery can improve specific clinical symptoms.

MSCT imaging of various shunts and grafts in post operative cases of congenital heart diseases

Background: Multi-slice computed tomography (MSCT) plays an important role in clinical practice in assessing post-operative patients with complex CHD when echocardiography is not contributory.  Despite the great capabilities of MR imaging for anatomic and functional assessment of the heart, it is time-consuming and may require a lengthy period of patient sedation; hence its use in seriously ill or uncooperative patients is often limited. CT has the advantages of widespread availability and short acquisition times. It is imperative for a radiologist to be aware of various palliative as well as corrective procedures and their various imaging findings. Aim of this article is to demonstrate and make one aware of various checklists and imaging findings in paediatric patients who have undergone various shunts and grafts at our tertiary cardiac care centre, their immediate as well as long term complications.Methods: We studied a total of 100 paediatric patients (<12 years old), who had undergone some sort of palliative or corrective shunt or graft placement, on MSCT during the period 2014 to 2018 at our tertiary cardiac care centre.Results: We try to outline details of various shunts and grafts used in congenital heart diseases correction, MSCT technique and imaging appearances and appearances of abnormal post-operative findings.Conclusions: Advances in computed tomography (CT) scanners and electrocardiographic gating techniques have resulted in superior image quality of the aorta and pulmonary arteries for evaluating postoperative congenital heart disease. MSCT is an excellent non-invasive modality for post-operative evaluation of various shunts and grafts.

Repercussão de intervenção educativa no conhecimento da equipe de enfermagem sobre os cuidados no uso da derivação ventricular externa em pediatria / Repercussion of an educational intervention on the knowledge of the nursing team regarding the use of external ventricular drains in pediatrics / Repercusión de la intervención educativa en el conocimiento del personal de enfermería sobre cuidados en el manejo del drenaje ventricular externo en pediatría

Objetivo: este estudo objetivou analisar a repercussão de intervenção educativa no conhecimento teórico da equipe de Enfermagem sobre os cuidados no uso da derivação ventricular externa em Pediatria. Trata-se de estudo de intervenção não controlado, com delineamento do tipo antes e depois. Método: procedeu-se à aplicação de pré e pós-teste para a coleta de informações sobre os conhecimentos dos profissionais sobre os cuidados aos pacientes pediátricos com derivação ventricular externa. Entre o pré e o pós-teste realizou-se intervenção educativa usando-se a simulação clínica como estratégia de ensino. Participaram do estudo 41 profissionais de Enfermagem. Constatou-se mais assertividade após a intervenção educativa, principalmente na questão que versa sobre o uso da técnica asséptica para esvaziamento da bolsa coletora (p=0,021). As análises de correlação no préteste revelaram que o maior número de erros não esteve correlacionado a qualquer das variáveis sociodemográficas. Contudo, no pós-teste, identificou-se correlação significativa entre o número de erros com a idade dos profissionais (rho=0,340; p=0,015); tempo de formação dos profissionais (rho= 0,414; p=0,004); e tempo de atuação na unidade (rho=0,428; p=0,004). O resultado sinaliza, portanto, que profissionais com idades mais elevadas, mais tempo de profissão e de atuação na unidade tiveram menos aproveitamento da intervenção educativa, apresentando maior número de erros. A intervenção educativa usando a estratégia da simulação clínica possibilitou incremento no conhecimento dos participantes, podendo ser utilizado para a educação permanente, melhorando a qualidade da assistência.(AU)

Objective: This study aimed to analyze the repercussion of an educational intervention on the theoretical knowledge of the Nursing team regarding the use of external ventricular drains in Pediatrics. This is an uncontrolled intervention study, with a before and after study design. Method: A pre- and post-test was applied to collect information on the nurses' knowledge regarding the care of pediatric patients with external ventricular drains. Between the pre- and post-test, an educational intervention was performed using clinical simulation as a teaching strategy. 41 nursing professionals participated in the study. The professionals were more assertive after the educational intervention, especially regarding the use of an aseptic technique for emptying the collection bag (p=0.021). Correlation analyses in the pre-test revealed that the greatest number of errors was not correlated to any of the socio-demographic variables. However, in the post-test, a significant correlation was identified between the number of errors and the participants' age (rho=0.340; p=0.015); years since graduation (rho=0.414; p=0.004); and years of professional experience in the unit (rho=0.428; p=0.004).

Emergency Pulmonary Artery–to-Systemic Artery Shunt to Break the Positive Feedback Loop of a Pulmonary Hypertensive Crisis after Neonatal Coarctation Repair / 대한흉부외과학회지

A 2.5-kg neonate with coarctation of the aorta and a small left ventricle experienced a severe pulmonary hypertensive crisis. An emergency pulmonary artery-to-systemic artery shunt was placed to break the positive feedback loop caused by pulmonary hypertension and functional mitral stenosis. This shunt provided immediate relief of suprasystemic pulmonary hypertension and the resultant low cardiac output.

Comparision between portosystemic shunts and endoscopic therapy for prevention of variceal re-bleeding: a systematic review and meta-analysis / 中华医学杂志(英文版)

Background:@#Portosystemic shunts, including surgical portosystemic shunts and transjugular intra-hepatic portosystemic shunt (TIPS), may have benefit over endoscopic therapy (ET) for treatment of variceal bleeding in patients with cirrhotic portal hypertension; however, whether there being a survival benefit among them remains unclear. This study was to compare the effect of three above-mentioned therapies on the short-term and long-term survival in patient with cirrhosis.@*Methods:@#Using the terms "variceal hemorrhage or variceal bleeding or variceal re-bleeding" OR "esophageal and gastric varices" OR "portal hypertension" and "liver cirrhosis," the Cochrane Central Register of Controlled Trials, PubMed, Embase, and the references of identified trials were searched for human randomized controlled trials (RCTs) published in any language with full texts or abstracts (last search June 2017). Risk ratio (RR) estimates with 95% confidence interval (CI) were calculated using random effects model by Review Manager. The quality of the included studies was evaluated using the Cochrane Collaboration’s tool for the assessment of the risk of bias.@*Results:@#Twenty-six publications comprising 28 RCTs were included in this analysis. These studies included a total of 2845 patients: 496 (4 RCTs) underwent either surgical portosystemic shunts or TIPS, 1244 (9 RCTs) underwent either surgical portosystemic shunts or ET, and 1105 (15 RCTs) underwent either TIPS or ET. There was no significant difference in overall mortality and 30-day or 6-week survival among three interventions. Compared with TIPS and ET, separately, surgical portosystemic shunts were both associated with a lower bleeding-related mortality (RR = 0.07, 95% CI = 0.01–0.32; P < 0.001; RR = 0.17, 95% CI = 0.06–0.51, P < 0.005) and rate of variceal re-bleeding (RR = 0.23, 95% CI = 0.10–0.51, P < 0.001; RR = 0.10, 95% CI = 0.04–0.24, P < 0.001), without a significant difference in the rate of postoperative hepatic encephalopathy (RR = 0.52, 95% CI = 0.25–1.00, P = 0.14; RR = 1.09, 95% CI = 0.59–2.01, P = 0.78). TIPS showed a trend toward lower variceal re-bleeding (RR = 0.46, 95% CI = 0.36–0.58, P < 0.001), but a higher incidence of hepatic encephalopathy than ET (RR = 1.78, 95% CI = 1.34–2.36, P < 0.001).@*Conclusions:@#The overall analysis revealed that there seem to be no short-term and long-term survival advantage, but surgical portosystemic shunts are with the lowest bleeding-related mortality among the three therapies. Surgical portosystemic shunts may be the most effective without an increased risk of hepatic encephalopathy and TIPS is superior to ET but at the cost of a higher incidence of hepatic encephalopathy. However, some of findings should be interpreted with caution due to the lower level of evidence and the existence of significant heterogeneity.

Outcomes of Carotid Endarterectomy according to the Anesthetic Method: General versus Regional Anesthesia / 대한흉부외과학회지

BACKGROUND: The surgical strategies for carotid endarterectomy (CEA) vary in terms of the anesthesia method, neurological monitoring, shunt usage, and closure technique, and no gold-standard procedure has been established yet. We aimed to analyze the feasibility and benefits of CEA under regional anesthesia (RA) and CEA under general anesthesia (GA).METHODS: Between June 2012 and December 2017, 65 patients who had undergone CEA were enrolled, and their medical records were prospectively collected and retrospectively reviewed. A total of 35 patients underwent CEA under RA with cervical plexus block, whereas 30 patients underwent CEA under GA. In the RA group, a carotid shunt was selectively used for patients who exhibited negative results on the awake test. In contrast, such a shunt was used for all patients in the GA group.RESULTS: There were no cases of postoperative stroke, cardiovascular events, or mortality. Nerve injuries were noted in 4 patients (3 in the RA group and 1 in the GA group), but they fully recovered prior to discharge. Operative time and clamp time were shorter in the RA group than in the GA group (119.29±27.71 min vs. 161.43±20.79 min, p<0.001; 30.57±6.80 min vs. 51.77±13.38 min, p<0.001, respectively). The hospital stay was shorter in the RA group than in the GA group (14.6±5.05 days vs. 18.97±8.92 days, p=0.022). None of the patients experienced a stroke or restenosis during the 27.23±20.3-month follow-up period.CONCLUSION: RA with a reliable awake test reduces shunt use and decreases the clamp and operative times of CEA, eventually resulting in a reduced length of hospital stay.

A Study On Type Of Branching Patterns Of Right Portal Vein

Introduction: The right hepatic lobe transplantation is usually the procedure of choice to provide adequate livervolume to the recipient. Variant vascular and biliary anatomy is more common in the right lobe. Knowledge ofanatomical variants is valuable in preoperative planning, particularly in considering donor candidates foradult-to-adult liver transplantation, whereby typically the right lobe of the donor is transplanted to the recipient.The present study was done to identify the branching patterns of right portal vein and to know their importancein management of living donor liver transplantation surgeries.Material and Methods: The present study was conducted on 84 liver specimens of human cadavers fixed with10% formalin, collected from the Department of Anatomy and Forensic Medicine, MMC&RI, Mysore.Results: Bifurcation of RPV was seen in 30 specimens (35.7%). Trifurcation of RPV was seen in 5 specimens (6%).Quadrification of RPV was seen in 18 specimens (21.4%). Arched pattern of RPV was seen in 15 specimens(17.9%). Premature origin of segment V and segment VIII vein from RPV, then trunk of RPV dividing terminally intosegment VI and segment VII vein was seen in 2 specimens (2.4%). Unusual pattern of division of RPV was seen in10 specimens (12%). In rest of 4 specimens there was no RPV as Right anterior and Right posterior portal veinswere directly arising from Main portal vein.Conclusion: Anatomical variations of the liver vasculature and bile ducts are common and their recognition andmanagement is critical in living donor liver transplantation. Although anomalies of the right lobe are commonlyencountered, a relatively limited number of cases will significantly complicate the resection and transplantation.Main advantage of right lobe transplantation is the large size of graft and surgical management of both donorand recipient anatomical variations is considerably simpler than with left sided graft

Infecciones asociadas a sistemas de derivación de líquido cefalorraquídeo en pediatría: análisis epidemiológico y de factores de riesgo de mortalidad / Cerebrospinal fluid shunt-associated infections in pediatrics: Analysis of the epidemiology and mortality risk factors

Introducción. La infección es de las complicaciones más frecuentes de los sistemas de derivación ventricular de líquido cefalorraquídeo. El objetivo fue describir las características clínicas, microbiológicas y evolutivas de niños con infección asociada a sistemas de derivación ventricular de líquido cefalorraquídeo y analizar los factores de riesgo, relacionados con la mortalidad. Población y métodos. Estudio descriptivo, retrospectivo, llevado a cabo en el Hospital "Prof. Dr. Juan P. Garrahan" de la Ciudad de Buenos Aires. Se evaluaron todos los pacientes internados desde el 1/1/2012 y el 31/12/2015 compatibles con ventriculitis y cultivo de líquido cefalorraquídeo positivo. Resultados. Se incluyeron 49 pacientes con 57 infecciones. La mediana de edad fue de 62 meses (rango intercuartílico: 19-114). Predominó el sexo masculino: 34 (70%). El tumor del sistema nervioso central fue la enfermedad de base más frecuente: 20 (40%). Se aisló estafilococo coagulasa negativo en 26 (46%), Staphylococcus aureus en 13 (23%), bacilos Gramnegativos en 11 (19%) y otros en 7 (12%). En 55 (97%) de las infecciones, se realizó tratamiento quirúrgico con retiro del sistema de derivación ventricular más antibioticoterapia. La mortalidad fue del 9%. Los únicos factores asociados a la mortalidad estadísticamente significativos fueron hemocultivos positivos (p= 0,04), fiebre al ingreso (p= 0,04) y shock séptico (p= 0,0006). Conclusiones. El estafilococo coagulasa negativo fue el germen más frecuente. El retiro de la válvula, junto con la antibioticoterapia, fue el tratamiento más utilizado. La presencia de fiebre al ingreso, hemocultivos positivos y shock séptico fueron predictores de mortalidad.

Introduction. Infections are the most common complications of ventricular cerebrospinal fluid shunts. The objective of this study was to describe the clinical, microbiological, and evolutionary characteristics of children with ventricular cerebrospinal fluid shunt-associated infections and analyze the risk factors for mortality. Population and methods. Descriptive, retrospective study carried out at Hospital "Prof. Dr. Juan P. Garrahan" in the Autonomous City of Buenos Aires. All patients hospitalized between January 1st, 2012 and December 31st, 2015 who were compatible with ventriculitis and had a positive cerebrospinal fluid culture were assessed. Results. A total of 49 patients with 57 infections were included. Their median age was 62 months (interquartile range: 19-114). Males predominated: 34 (70%). A central nervous system tumor was the most common underlying disease: 20 (40%). Coagulase-negative Staphylococcus was isolated in 26 (46%); Staphylococcus aureus, in 13 (23%); Gram-negative bacilli, in 11 (19%); and other microorganism, in 7 (12%). Treatment consisted of removal of ventricular shunt plus antibiotic therapy for 55 (97%) infections. The mortality rate was 9%. The only statistically significant factors associated with mortality were positive blood cultures (p= 0.04), fever at the time of admission (p= 0.04), and septic shock (p= 0.0006). Conclusions. Coagulase-negative Staphylococcus was the most common microorganism. Valve removal plus antibiotic therapy was the most frequently instituted treatment. Fever at the time of admission, positive blood cultures, and septic shock were predictors of mortality.
