Abstract

OBJECTIVE: The new 2019 guideline of the European Society for Vascular Surgery (ESVS) recommends consideration for elective iliac artery aneurysm (eIAA) repair when the iliac diameter exceeds 3.5 cm, as opposed to 3.0 cm previously. The current study assessed diameters at time of eIAA repair and ruptured IAA (rIAA) repair and compared clinical outcomes after open surgical repair (OSR) and endovascular aneurysm repair (EVAR).METHODS: This retrospective observational study used the nationwide Dutch Surgical Aneurysm Audit (DSAA) registry that includes all patients who undergo aorto-iliac aneurysm repair in the Netherlands. All patients who underwent primary IAA repair between 1 January 2014 and 1 January 2018 were included. Diameters at time of eIAA and rIAA repair were compared in a descriptive fashion. The anatomical location of the IAA was not registered in the registry. Patient characteristics and outcomes of OSR and EVAR were compared with appropriate statistical tests.RESULTS: The DSAA registry comprised 974 patients who underwent IAA repair. A total of 851 patients were included after exclusion of patients undergoing revision surgery and patients with missing essential variables. eIAA repair was carried out in 713 patients, rIAA repair in 102, and symptomatic IAA repair in 36. OSR was performed in 205, EVAR in 618, and hybrid repairs and conversions in 28. The median maximum IAA diameter at the time of eIAA and rIAA repair was 43 (IQR 38-50) mm and 68 (IQR 58-85) mm, respectively. Mortality was 1.3% (95% CI 0.7-2.4) after eIAA repair and 25.5% (95% CI 18.0-34.7) after rIAA repair. Mortality was not significantly different between the OSR and EVAR subgroups. Elective OSR was associated with significantly more complications than EVAR (intra-operative: 9.8% vs. 3.6%, post-operative: 34.0% vs. 13.8%, respectively).CONCLUSION: In the Netherlands, most eIAA repairs are performed at diameters larger than recommended by the ESVS guideline. These findings appear to support the recent increase in the threshold diameter for eIAA repair.

Abstract

Lean management en transactiemanagement bieden een verschillend perspectief voor de bedrijfsorganisatie om tot kostenreductie te geraken. Lean management is gericht op het voorkomen van verspilling in productieprocessen en is ontleend aan de bedrijfspraktijk. Daarentegen ligt de focus van transactiemanagement op het laag houden van transactiekosten bij de interne en externe organisatie van het bedrijf. Daarbij gaat het om waardecreatie op de lange termijn. Beide methoden kunnen elkaar aanvullen bij strategische managementbeslissingen.

Abstract

In de trend van globalisering en toenemende fragmentatie van productie gaat de Nederlandse industrie zich steeds meer op de regiefunctie toeleggen. Dit artikel bespreekt deze transitie vanuit het perspectief van de moderne theorieën van de internationale handel, transactiekosten en industriële organisatie, met de onderneming IHC Holland Merwede als voorbeeld. Deze casus staat model voor dergelijke transitieprocessen in andere onderdelen van de maakindustrie en is tevens van belang voor het innovatie-, onderwijs- en arbeidsmarktbeleid van de overheid.

Abstract

Background: To compare hospital outcomes of aortic aneurysm surgery, casemix correction for preoperative variables is essential. Most of these variables can be deduced from mortality risk prediction models. Our aim was to identify the optimal set of preoperative variables associated with mortality to establish a relevant and efficient casemix model.Methods: All patients prospectively registered between 2013 and 2016 in the Dutch Surgical Aneurysm Audit (DSAA) were included for the analysis. After multiple imputation for missing variables, predictors for mortality following univariable logistic regression were analyzed in a manual backward multivariable logistic regression model and compared with three standard mortality risk prediction models: Glasgow Aneurysm Score (GAS, mainly clinical parameters), Vascular Biochemical and Haematological Outcome Model (VBHOM, mainly laboratory parameters), and Dutch Aneurysm Score (DAS, both clinical and laboratory parameters). Discrimination and calibration were tested and considered good with a C-statistic > 0.8 and Hosmer-Lemeshow (H-L) P > 0.05.Results: There were 12,401 patients: 9,537 (76.9%) elective patients (EAAA), 913 (7.4%) acute symptomatic patients (SAAA), and 1,951 (15.7%) patients with acute rupture (RAAA). Overall postoperative mortality was 6.5%; 1.8% after EAAA surgery, 6.6% after SAAA, and 29.6% after RAAA surgery. The optimal set of independent variables associated with mortality was a mix of clinical and laboratory parameters: gender, age, pulmonary comorbidity, operative setting, creatinine, aneurysm size, hemoglobin, Glasgow coma scale, electrocardiography, and systolic blood pressure (C-statistic 0.871). External validation overall of VBHOM, DAS, and GAS revealed C-statistics of 0.836, 0.782, and 0.761, with an H-L of 0.028, 0.00, and 0.128, respectively.Conclusions: The optimal set of variables for casemix correction in the DSAA comprises both clinical and laboratory parameters, which can be collected easily from electronic patient files and will lead to an efficient casemix model.

Abstract

BACKGROUND: Colonic ischemia remains a severe complication after abdominal aortic aneurysm (AAA) repair and is associated with a high mortality. With open repair being one of the main risk factors of colonic ischemia, deciding between endovascular or open aneurysm repair should be based on tailor-made medicine. This study aims to identify high-risk patients of colonic ischemia, a risk that can be taken into account while deciding on AAA treatment strategy.METHODS: A nationwide population-based cohort study of 9,433 patients who underwent an AAA operation between 2014 and 2016 was conducted. Potential risk factors were determined by reviewing prior studies and univariate analysis. With logistic regression analysis, independent predictors of intestinal ischemia were established. These variables were used to form a prediction model.RESULTS: Intestinal ischemia occurred in 267 patients (2.8%). Occurrence of intestinal ischemia was seen significantly more in open repair versus endovascular aneurysm repair (7.6% vs. 0.9%; P < 0.001). This difference remained significant after stratification by urgency of the procedure, in both intact open (4.2% vs. 0.4%; P < 0.001) and ruptured open repair (15.0% vs. 6.2%); P < 0.001). Rupture of the AAA was the most important predictor of developing intestinal ischemia (odds ratio [OR], 5.9, 95% confidence interval [CI] 4.4-8.0), followed by having a suprarenal AAA (OR 3.4; CI 1.1-10.6). Associated procedural factors were open repair (OR 2.8; 95% CI 1.9-4.2), blood loss >1L (OR 3.6; 95% CI 1.7-7.5), and prolonged operating time (OR 2.0; 95% CI 1.4-2.8). Patient characteristics included having peripheral arterial disease (OR 2.4; 95% CI 1.3-4.4), female gender (OR 1.7; 95% CI 1.2-2.4), renal insufficiency (OR 1.7; 1.3-2.2), and pulmonary history (OR 1.6; 95% CI 1.2-2.2). Age CONCLUSIONS: One of the main risk factors is open repair. Several other risk factors can contribute to developing colonic ischemia after AAA repair. The proposed prediction model can be used to identify patients at high risk for developing colonic ischemia. With the current trend in AAA repair leaning toward open repair for better long-term results, our prediction model allows a better informed decision can be made in AAA treatment strategy.

Abstract

Contains fulltext : 226470.pdf (Publisher’s version ) (Closed access) OBJECTIVE: Mycotic aneurysms of the abdominal aorta (MAAA) can be treated by open repair (OR) or endovascular aneurysm repair (EVAR). This nationwide study provides an overview of the situation of MAAA treatment in The Netherlands in 2016. METHODS: A retrospective cohort study was conducted with all centers that registered aortic abdominal aneurysms in the Dutch Surgical Aneurysm Audit in 2016. Questionnaires on 1-year outcomes were sent to all centers that treated patients with MAAA. The primary aim was to determine 30-day and 1-year mortality and morbidity of OR- and EVAR-treated patients. Morbidity was determined by the need for reoperations and the number of readmissions to the hospital. RESULTS: Twenty-six MAAA were detected in the Dutch Surgical Aneurysm Audit database of 2016, resulting in an incidence of 0.7% of all registered abdominal aortic aneurysms. The 30-day mortality for OR and EVAR treated patients was 1 in 13 and 0 in 13, respectively. Major and minor reinterventions within 30 days were needed for two (one OR and one EVAR) and two (one OR and one EVAR) patients, respectively. Two patients (15.4%) in the OR group and one patient (7.7%) in the EVAR group were readmitted to hospital within 30 days. In total, 1-year outcomes of 23 patients were available. In the OR group, one patient (9.1%) died in the first postoperative year. There was one major reintervention (removal of endoprosthesis and spiralvein reconstruction) in the EVAR group. Two patients (18.2%) treated with OR and two (16.7%) treated with EVAR required a minor reintervention. In both groups, four patients (OR, 36.4%; EVAR, 33.3%) were readmitted to hospital within 1 year postoperatively. CONCLUSIONS: Both OR- and EVAR-treated patients show acceptable clinical outcomes after 30 days and at the 1-year follow-up. Depending on the clinical course of the patient, EVAR may be considered in the management of this disease.

Abstract

Objectives: Failure to rescue (FTR) is a composite quality indicator, defined as the proportion of deceased patients following major complications. The aims of this study were to compare FTR with mortality for hospital comparisons in abdominal aortic aneurysm (AAA) surgery in The Netherlands and investigate hospital volume and associated factors.Methods: Patients prospectively registered between 2013 and 2015 in the Dutch Surgical Aneurysm Audit (DSAA) were analysed. FTR was analysed for AAA patients and subgroups elective (EAAA) and acute (AAAA; symptomatic or ruptured) aneurysms. Variables and hospital volume were analysed by uni- and multivariable regression analysis. Adjusted hospital comparisons for mortality, major complications, and FTR were presented in funnel plots. Isomortality lines were constructed when presenting FTR and major complication rates.Results: A total of 9258 patients were analysed in 61 hospitals: 7149 EAAA patients (77.2%) and 2109 AAAA patients (22.8%). There were 2785 (30.1%) patients with complications (unadjusted range 5-65% per hospital): 2161 (77.6%) with major and 624 (28.4%) patients with minor complications. Overall mortality was 6.6% (adjusted range 0-16% per hospital) and FTR was 28.4% (n = 613) (adjusted range 0-60% per hospital). Glasgow Coma Scale, age, pulse, creatinine, electrocardiography, and operative setting were independently associated with FTR. Hospital volume was not associated with FTR. In AAAA patients hospital volume was significantly associated with a lower adjusted major complication and mortality rate (OR 0.62, 95% CI 0.49-0.78; and 0.64, 95% CI 0.48-0.87). Four hospitals had a significant lower adjusted FTR with different major complication rates on different isomortality lines.Conclusions: There was more variation in FTR than in mortality between hospitals. FTR identified the same best performing hospitals as for mortality and therefore was of limited additional value in measuring quality of care for AAA surgery. FTR can be used for internal quality improvement with major complications in funnel plots and diagrams with isomortality lines. (C) 2018 European Society for Vascular Surgery.

Abstract

Background: The Dutch Audit for Carotid Interventions (DACI) registers all patients undergoing interventions for carotid artery stenosis in the Netherlands. This study describes the design of the DACI and results of patients with a symptomatic stenosis undergoing carotid endarterectomy (CEA). It aimed to evaluate variation between hospitals in process of care and (adjusted) outcomes, as well as predictors of major stroke/death after CEA.Methods: All patients with a symptomatic stenosis, who underwent CEA and were registered in the DACI between 2014 and 2016 were included in this cohort. Descriptive analyses of patient characteristics, process of care, and outcomes were performed. Casemix adjusted hospital procedural outcomes as (30 day/in hospital) mortality, stroke/death, and major stroke/death, were compared with the national mean. A multivariable logistic regression model (backward elimination at p > 0.10) was used to identify predictors of major stroke/death.Results: A total of 6459 patients, registered by 52 hospitals, were included. The majority (4,832, 75%) were treated Conclusion: CEA in The Netherlands is associated with an overall low mortality and (major) stroke/death rate. Whereas the indicator time to intervention varied between hospitals, mortality and (major) stroke/death were not significantly distinctive enough to identify worse practices and therefore were unsuitable for hospital comparison in the Dutch setting. Additionally, predictors of major stroke/death at population level could be identified. (C) 2018 European Society for Vascular Surgery. Published by Elsevier B.V. All rights reserved.

Abstract

This era of globalization is characterized by an ongoing international fragmentation of production where the supply chain is split up in more and more parts. The traditional Ricardian theory of trade in products governed by comparative advantages is replaced by a modern theory of trade in tasks. This trend requires new entrepreneurial skills in the organization of production. Tasks are outsourced to those places in the world where the lower production costs outweigh the additional transaction costs associated with the fragmentation of production. This managing of transaction costs, which we label transaction management, has become a major entrepreneurial skill in transaction economies like the Netherlands. It is determinant for the "make or buy" and location decisions. This paper investigates the practice of transaction management by using data from in-depth interviews with seven companies in the Netherlands which are actually engaged in this modern way of organizing production. It shows that the various ways of coping with transaction costs in the organization of production play an important role in the strategic decision making of the internationally operating entrepreneurs. However, transaction costs are only intuitively dealt with in organizing production. Therefore it seems that support from more formal argumentation, based on the theories of transaction cost economics and new institutional economics, is warranted.

Abstract

The University of Wisconsin (UW) solution consists of a relatively complex mixture of agents. In this study we compared simpler preservation solutions, namely, histidine-tryptophan-ketoglutarate (HTK) and phosphate-buffered sucrose (PBS) with different compositions of UW solution in the isolated perfused rabbit liver model. Livers were stored cold for 24 and 48 h. After 24 h of preservation, the amount of bile produced in UW-preserved livers was significantly greater (P < 0.05) than that in HTK-preserved livers. Also, there was less LDH released into the perfusate in UW-preserved livers. There was more edema and lower K +/Na + rations in HTK-preserved livers than in UW-preserved livers (all data P < 0.05). After 48 h of preservation, the differences between livers preserved in UW or HTK solution were less noticeable than at 24 h and bile production was similar. LDH and AST release were greater in HTK-preserved livers than in UW livers, but these differences were not statistically significant. Preservation in PBS for 48 h was worse than in either UW or HTK solution. Substitution of polyethylene glycol (PEG) for hydroxyethyl starch (HES) in 48-h UW-preserved livers was not effective. We conclude that solutions simpler in composition than UW solution may be effective in kidney transplantation but do not appear suitable for successful liver preservation.

Abstract

To determine the relation between tissue hydration state-as indicated by tissue proton magnetic resonance relaxation times-in UW-preserved human donor livers and viability parameters of the donor and early graft function, ''ex vivo'' magnetic resonance relaxometry was performed with a clinical MR imaging system. Relaxometric data were obtained from MR images in which signal intensities were directly proportional to T-1 and T-2. Forty three subsequently transplanted livers and five discarded livers were studied. The donor serum concentrations of direct and total bilirubin had a positive correlation with T-1 (P

Abstract

This article discusses government regulation and the consequent compliance costs for the private sector from the perspective of transaction cost economics. In many cases, government regulation is shaped as legally binding standards. In order to comply with these standards, private sector firms meet various types of transaction costs, such as the bonding costs that the principal/agent relationship of government regulation brings about. On the other hand, good standards may reduce transaction costs. Therefore, optimal design of government regulation requires the design of standards with the lowest possible transaction costs. Due to network externalities and economics of scale, and in order to guarantee a level playing field, good coordination and unifying standards within the EU can be beneficial. This article provides examples of such standards.

Abstract

This paper discusses the design, implementation and use of standards from the perspective of transaction costs economics. A proper design and implementation of standards may lead to a considerable reduction of transaction costs, which enhances trade and, consequently, economic welfare. A major example is the use of containers, which has drastically changed the worldwide transport infrastructure, and lowered the costs of transport of goods considerably. The example of containers also shows that network externalities play a major role in the use of standards, and that, on the other hand, worldwide standards with large sunk investment costs may lead to a lock-in. This may call for government intervention in the design and use of standards, and in the transition processes to new standards. The paper provides ample further examples of standards and on the role of the government, or clubs, with respect to these standards.

Abstract

This chapter gives an economic perspective on the assessment of the election programmes by CPB Netherlands Bureau for Economic Policy Analysis (CPB). There are at least two ways for giving such economic perspective. The first way is to consider what body of economic knowledge is used in the assessment and to see whether the use of these economic methods is viable for the purpose of the exercise. In so far as this contribution takes this broad perspective, there is some overlap with the other chapters in this book. Another way is, however, to look at the assessment from a more narrow economic perspective, namely to consider the value of the exercise and to see whether its social benefits exceed the costs. In this chapter I will consider the CPB assessment mainly from the latter perspective, although I will not try to conduct a formal cost-benefit analysis. All-in-all it seems to me that this exercise adds enough value to the process of policy making as to be regarded as valuable. Yet it does not serve the most obvious purpose, namely that it helps the citizens of the Netherlands to decide about their votes.

Abstract

The interaction between empirical modellers and policy makers is analyzed in terms of the structure of the industry, the products involved, the value chain and its working arrangements. Our account of successful interaction focuses on models as the site for knowledge creation and consensus building in both forecasting and policy analysis. The application of network analysis and ideas from knowledge management enable us to interpret the structures and the institutional arrangements described in a range of case studies. We explain why some institutional arrangements may lead to helpful interaction, but our analysis suggests that the way a structure is used is more critical than the nature of the structure in determining the success of interaction between modellers and policy makers.

Abstract

Glycine has been shown to decrease membrane injury in isolated cells due to hypoxia or cold ischemia. The mechanisms of action of glycine are not known, but glycine may be useful in organ preservation solutions or in treating recipients of liver transplantation. In this study the isolated, perfused rabbit liver was used to measure how glycine affected liver performance after 48-h preservation in University of Wisconsin (UW) solution without added glutathione. UW solution is less effective for 48-h liver preservation when glutathione is omitted. Rabbit livers stored for 48 h without glutathione show a large increase in enzyme release (LDH and AST) from the liver and a reduction in bile production. The addition of 15 mM glycine to UW solution, in place of glutathione, did not improve bile production or reduce enzyme release. However, infusion of 10 mM glycine into the reperfused liver lowered LDH release significantly (from 2383 +/- 562 units/100 g to 1426 +/- 286 units/100 g) during the initial reperfusion of the 48-h preserved liver. Hepatamine, a parenteral nutrition solution containing glycine, as well as other amino acids, was also effective in lowering LDH release from the preserved liver. Although glycine reduced LDH release, it did not decrease the amount of AST released from the liver, nor did it improve bile production. Thus, we conclude that glycine, either in UW solution or given to the liver upon reperfusion, has no significantly beneficial effect as tested in this model. Further testing of glycine, however, should be conducted in an orthotopic transplant model in the rat or dog.

Abstract

To determine the relation between tissue hydration state--as indicated by tissue proton magnetic resonance relaxation times--in UW-preserved human donor livers and viability parameters of the donor and early graft function, "ex vivo" magnetic resonance relaxometry was performed with a clinical MR imaging system. Relaxometric data were obtained from MR images in which signal intensities were directly proportional to T1 and T2. Forty-three subsequently transplanted livers and five discarded livers were studied. The donor serum concentrations of direct and total bilirubin had a positive correlation with T1 (P0.05 and P0.01, respectively). Sequential measurements in 7 livers demonstrated a firm time relation between the cold storage time and the length of the relaxation times. As cold storage time lengthened, T1 and T2 shortened. T1 of the donor liver showed a significant negative correlation with recipient ASAT and ALAT values on days 1, 2, and 3 after transplantation. T1 in the discarded group was significantly higher than T1 in the accepted group. T2 was not different in the two groups. It is concluded that in UW-preserved human donor livers, the tissue hydration state, as indicated by the tissue MR relaxation times, is largely independent of the clinical condition of the organ donor and the preservation procedure. An optimum tissue hydration state, in UW-preserved donors liver might have protective properties against parenchymal damage, although the clinical consequences appear to be of minor importance. The capacity of relaxometry as a discriminative instrument to accept or to discard donor livers is poor.

Abstract

Glycine has been shown to protect renal tubule cells and hepatocytes from ischemia, ATP depletion, and cold storage injury. Glycine may be a useful additive to organ preservation solutions or suppress reperfusion injury by infusion into recipients of liver transplantation. In this study, the effects of glycine on survival and postoperative liver injury were studied in the rat and dog orthotopic transplant model. Rat livers preserved for 30 hr in the University of Wisconsin (UW) solution were 50% viable (3 of 6 survivors for 7 days). When glutathione was replaced by 10 mM glycine, survival increased to 100% (6 of 6). There was a significant reduction in hepatocellular injury at the end of preservation (lactate dehydrogenase [LDH] in the pretransplant flush-out of the liver was lower in the glycine group) and after transplantation (serum LDH concentration 6 hr after transplant was lower in the glycine group). In the dog, omission of glutathione from the UW solution resulted in 33% survival (48-hr preservation model) versus 100% survival with glutathione. Replacing glutathione in the UW solution by glycine did not improve survival (33% after 48 hr of preservation). However, when glycine was given to recipients of livers preserved in the UW solution for 24 or 48 hr, there was a decrease in the degree of hepatocellular injury. After 48 hr of preservation, peak aspartate aminotransferase, alanine aminotransferase, and LDH were reduced by about 45-55% when glycine was given to the recipient. Although the differences, with and without glycine treatment of the recipients, did not reach statistical significance, there was a noticeable reduction in hepatocellular injury with glycine. There was 100% survival of dogs in the groups that received livers preserved with the UW solution plus or minus glycine infusion. Hepatamine, a parenteral nutrition solution containing glycine and other amino acids increased hepatocellular injury (higher concentrations of aspartate aminotransferase, alanine transferase, and LDH versus control 48-hr preserved livers), although all dogs survived. This study shows that glycine is cytoprotective when administered to recipients of livers preserved for 24 or 48 hr and suppresses hepatocellular injury, as reflected in a reduction in the concentration of serum enzymes. However, the differences, with and without glycine, were, at best, marginal and further studies are needed to determine whether glycine would make a significant improvement in liver preservation and prevent primary nonfunction.

26. Glycin verhindert Hydroxylradikal-, Ca++- und Phospholipase A2-induzierten Reperfusionsschaden in der Nierenkonservierung

Author

Belzer Fo, M. Schilling, James H. Southard, G. Den Butter, and B. Tilton

Abstract

Mit Einfuhrung der UW-Losung in die Transplantationschirurgie konnte die Konservierungszeit insbesondere fur Leber und Pankreas sowohl im experimentellen als auch im klinischen Bereich deutlich verlangert werden. Eine der wesentlichsten Komponenten der UW-Losung scheint der intracellulare Sauerstoffradikalscavenger Glutathion (GSH) in seiner reduzierten Form zu sein [1]. In wassrigen Losungen verliert GSH durch Autooxidation jedoch schnell seine Reduktions- und somit Wirkungsfahigkeit [2] und fuhrt als oxidiertes Glutathion (GSSG) in der Lebertransplantation zu einem vermehrten primaren Transplantatversagen [2]. Des weiteren wird GSH vor Aufnahme ins Cytosol durch die membranstandige g-Glutamyl-transpeptidase und eine unspezifische intracellulare Dipep- tidase in seine Bestandteue Glutamin, Cystein und Glycin (Gly) zerlegt und intracellular unter ATP-Verbrauch zum funktionsfahigen Tripeptid resynthetisiert Dieser endogene Re- syntheseprozes scheint bei cold storage Bedingungen (niedrige Temperaturen und Anoxie) thermodynamisch auserst unwahrscheinlich. Wahrend der protektive Effekt von reduziertem GSH in Organkonservierungslosungen am Transplantationsmodell zweifelsfrei nachgewiesen ist, bleibt der molekulare Mechanismus dieser Protektion weiterhin ungeklart. Von Gly, der C-terminalen Aminosaure des GSH hingegen ist bekannt, das sie Hepatocyten sowie isolierte proximale Nierentubuli gegen Hypoxie und eine Reihe von Toxinen wie CCCLP, Adriamycin, Quabain moglicherweise durch einen unspezifischen membranstabilisierenden Effekt schutzt [3]. In vorliegender Studie wurde zuerst am cellularen Modell untersucht, ob Gly Nieren gegen induzierte Ischamie- und Reperfusionsschaden schutzt.

Abstract

We report the case of a 44-year-old woman who had extensive stenosis and dilatation of the aortoiliac arteries and an aneurysm of the superior mesenteric artery as a result of fibrodysplasia. Both the aortoiliac and the superior mesenteric arteries were treated by resection and reconstruction. Within one year after this operation, fibrodysplastic aneurysms developed in previously angiographically normal visceral arteries. The patient came to us with massive lower gastrointestinal bleeding caused by rupture of a visceral fibrodysplastic aneurysm of the middle colic artery into the transverse colon. The classification, the origin, the localization, and the natural history of fibrodysplasia are discussed. (J VASC SURG 1988;7:449-53.)

Abstract

INTRODUCTIONAn aberrant right subclavian artery (ARSA) or lusorian artery is one of the most common variations of the aortic arch. Although usually without symptoms, some ARSA's occasionally become symptomatic.PRESENTATION OF CASEA 51-year old woman presented with a painful right middle finger. Clinical examination showed thenar muscle hypotrophy and blue discoloration of the distal phalanx suggestive of embolization. Magnetic resonance angiography revealed a non-aneurysmal proximally occluded ARSA. A venous common carotid artery to subclavian artery bypass was combined with ARSA ligation proximal to the right vertebral artery.DISCUSSIONOcclusive symptomatic ARSA disease without aneurysmal dilatation is uncommon. Treatment may include bypass grafting by open surgery or angioplasty with stenting.CONCLUSIONTreatment for occlusive non-aneurysmal ARSA must be tailored to the individual. Whether an endovascular or surgical approach is preferred depends on localization of the lesion in relation to the esophagus and on the general condition of the patient.

Abstract

The immediate side effects of lymphocyte-specific monoclonal antibody treatment of nearly 150 monkeys is documented in this study. Immediate side effects were only seen with antibodies specific for CD3 and CD8. These side effects are most likely related to stimulation of T cells to produce lymphokines (CD3) and/or to the rapid cell clearance (CD3 and CD8). No immediate effects were observed when CD4 or major histocompatibility complex class II-specific antibodies were injected. These antibodies may therefore be considered for the treatment of graft rejection or autoimmune diseases. Of the 43 animals that received a monoclonal antibody (MoAb) at least 2 years and up to 5 years prior to this study, none has shown any late effects of MoAb treatment. Most animals tested had a vigorous immune response to the injected MoAbs, both antiidiotypic as well as anti-isotypic antibodies were formed. This response was reduced by using Fab2 fragments or by additional immunosuppression, but it was still high enough to prevent further effectiveness of the MoAb treatment.

Abstract

Background: The low incidence rate of adrenocortical carcinoma (ACC) requires a multidisciplinary approach in which surgery plays an essential role because complete resection of the primary tumor is the only chance of cure. To improve patient care, insight into operative results within the ACC population is essential. In 2007, a Dutch Adrenal Network Registry was created covering care and outcome of patients treated for ACC in the Netherlands since 1965. Using this database, we performed a study (1) to gain insight into surgical performance in the Netherlands and (2) to compare operative data with international literature., Methods: Data on patients treated from 1965 until January 2008 were studied. The following data were collected: age, gender, functionality of the tumor, stage at diagnosis, operative procedure, completeness of surgery, disease recurrence, adjuvant mitotane therapy, and recurrence-free and overall survival (OS)., Results: A total of 175 patients were studied, of whom 149 underwent surgery. Patients with complete resection had significantly longer OS times than patients with incomplete resection (P = .010). Patients operated on in a Dutch Adrenal Network center had significantly longer duration of OS in both univariate (P = .011) and multivariate analysis (P = .014). A significantly greater OS was observed for operated stage IV patients compared with nonoperated patients (P = .002)., Conclusion: Our data suggest the relevance of national cooperation and centralized surgery in ACC. For selected patients with stage IV disease, surgery can be beneficial in extending survival. On the basis of the retrospective analysis, operative ACC in the Netherlands can and will be improved., (Copyright © 2012. Published by Mosby, Inc.)

Abstract

The University of Wisconsin (UW) solution consists of a relatively complex mixture of agents. In this study we compared simpler preservation solutions, namely, histidine-tryptophan-ketoglutarate (HTK) and phosphate-buffered sucrose (PBS) with different compositions of UW solution in the isolated perfused rabbit liver model. Livers were stored cold for 24 and 48 h. After 24 h of preservation, the amount of bile produced in UW-preserved livers was significantly greater (P < 0.05) than that in HTK-preserved livers. Also, there was less LDH released into the perfusate in UW-preserved livers. There was more edema and lower K +/Na+rations in HTK-preserved livers than in UW-preserved livers (all data P < 0.05). After 48 h of preservation, the differences between livers preserved in UW or HTK solution were less noticeable than at 24 h and bile production was similar. LDH and AST release were greater in HTK-preserved livers than in UW livers, but these differences were not statistically significant. Preservation in PBS for 48 h was worse than in either UW or HTK solution. Substitution of polyethylene glycol (PEG) for hydroxyethyl starch (HES) in 48-h UW-preserved livers was not effective. We conclude that solutions simpler in composition than UW solution may be effective in kidney transplantation but do not appear suitable for successful liver preservation.

Abstract

Glycine has been shown to decrease membrane injury in isolated cells due to hypoxia or cold ischemia. The mechanisms of action of glycine are not known, but glycine may be useful in organ preservation solutions or in treating recipients of liver transplantation. In this study the isolated, perfused rabbit liver was used to measure how glycine affected liver performance after 48-h preservation in University of Wisconsin (UW) solution without added glutathione. UW solution is less effective for 48-h liver preservation when glutathione is omitted. Rabbit livers stored for 48 h without glutathione show a large increase in enzyme release (LDH and AST) from the liver and a reduction in bile production. The addition of 15 mM glycine to UW solution, in place of glutathione, did not improve bile production or reduce enzyme release. However, infusion of 10 mM glycine into the reperfused liver lowered LDH release significantly (from 2383 +/- 562 units/100 g to 1426 +/- 286 units/100 g) during the initial reperfusion of the 48-h preserved liver. Hepatamine, a parenteral nutrition solution containing glycine, as well as other amino acids, was also effective in lowering LDH release from the preserved liver. Although glycine reduced LDH release, it did not decrease the amount of AST released from the liver, nor did it improve bile production. Thus, we conclude that glycine, either in UW solution or given to the liver upon reperfusion, has no significantly beneficial effect as tested in this model. Further testing of glycine, however, should be conducted in an orthotopic transplant model in the rat or dog.

Abstract

To determine the relation between tissue hydration state--as indicated by tissue proton magnetic resonance relaxation times--in UW-preserved human donor livers and viability parameters of the donor and early graft function, "ex vivo" magnetic resonance relaxometry was performed with a clinical MR imaging system. Relaxometric data were obtained from MR images in which signal intensities were directly proportional to T1 and T2. Forty-three subsequently transplanted livers and five discarded livers were studied. The donor serum concentrations of direct and total bilirubin had a positive correlation with T1 (P < 0.05 and P < 0.01, respectively). Sequential measurements in 7 livers demonstrated a firm time relation between the cold storage time and the length of the relaxation times. As cold storage time lengthened, T1 and T2 shortened. T1 of the donor liver showed a significant negative correlation with recipient ASAT and ALAT values on days 1, 2, and 3 after transplantation. T1 in the discarded group was significantly higher than T1 in the accepted group. T2 was not different in the two groups. It is concluded that in UW-preserved human donor livers, the tissue hydration state, as indicated by the tissue MR relaxation times, is largely independent of the clinical condition of the organ donor and the preservation procedure. An optimum tissue hydration state, in UW-preserved donors liver might have protective properties against parenchymal damage, although the clinical consequences appear to be of minor importance. The capacity of relaxometry as a discriminative instrument to accept or to discard donor livers is poor.

Abstract

Glycine has been shown to protect renal tubule cells and hepatocytes from ischemia, ATP depletion, and cold storage injury. Glycine may be a useful additive to organ preservation solutions or suppress reperfusion injury by infusion into recipients of liver transplantation. In this study, the effects of glycine on survival and postoperative liver injury were studied in the rat and dog orthotopic transplant model. Rat livers preserved for 30 hr in the University of Wisconsin (UW) solution were 50% viable (3 of 6 survivors for 7 days). When glutathione was replaced by 10 mM glycine, survival increased to 100% (6 of 6). There was a significant reduction in hepatocellular injury at the end of preservation (lactate dehydrogenase [LDH] in the pretransplant flush-out of the liver was lower in the glycine group) and after transplantation (serum LDH concentration 6 hr after transplant was lower in the glycine group). In the dog, omission of glutathione from the UW solution resulted in 33% survival (48-hr preservation model) versus 100% survival with glutathione. Replacing glutathione in the UW solution by glycine did not improve survival (33% after 48 hr of preservation). However, when glycine was given to recipients of livers preserved in the UW solution for 24 or 48 hr, there was a decrease in the degree of hepatocellular injury. After 48 hr of preservation, peak aspartate aminotransferase, alanine aminotransferase, and LDH were reduced by about 45-55% when glycine was given to the recipient. Although the differences, with and without glycine treatment of the recipients, did not reach statistical significance, there was a noticeable reduction in hepatocellular injury with glycine. There was 100% survival of dogs in the groups that received livers preserved with the UW solution plus or minus glycine infusion. Hepatamine, a parenteral nutrition solution containing glycine and other amino acids increased hepatocellular injury (higher concentrations of aspartate aminotransferase, alanine transferase, and LDH versus control 48-hr preserved livers), although all dogs survived. This study shows that glycine is cytoprotective when administered to recipients of livers preserved for 24 or 48 hr and suppresses hepatocellular injury, as reflected in a reduction in the concentration of serum enzymes. However, the differences, with and without glycine, were, at best, marginal and further studies are needed to determine whether glycine would make a significant improvement in liver preservation and prevent primary nonfunction.
