Abstract
We report about a patient presenting with back pain 4 months after an uneventful endovascular implantation of an aortic stent graft. Computed tomography scan revealed a migration of the stent with consecutive endoleakage, kink formation, and movement of the stent toward the spine, which caused destruction of the aortic wall as well as vertebral necrosis. Explantation of the stent and replacement of the native aorta relieved the patient of his symptoms.

Abstract
OBJECTIVE The aim of the present study was to evaluate different statements in the literature on the influence of the sampling site on various blood parameters in a larger amount of animals. In addition, the practical usability of blood sampling from the udder vein or other accessible veins (e. g. saphenous vein or tail vein) in comparison to the jugular vein for metabolic analyses should be verified. MATERIAL AND METHODS For this purpose blood samples from 92 cows and heifers were taken from the jugular vein, the udder vein and the saphenous vein of the left and right hind limb at four different time points (from 3 weeks ante partum until 8 weeks post partum) and comparatively investigated. RESULTS For five of the 16 investigated parameters (free fatty acids, beta-hydroxybutyrate, glucose, creatine kinase, and calcium) partially high significant differences between the sampling sites became apparent, dependant on the moment of analysis. CONCLUSION AND CLINICAL RELEVANCE In metabolic analyses, which comprise the aforementioned parameters, the blood sampling site has decisively influence and has to be considered in the interpretation. The udder vein represents no alternative for blood sampling in high yielding cows for metabolic analyses. For obtaining meaningful results, the jugular vein has to be used for blood sampling, despite the higher procedural effort. An exception is the determination of the creatine kinase activity. Since defence movements of the animal's neck seem to have an influence on the local activity, the udder vein should be preferred as sampling site.

Abstract
Early vascularization of a composite in a critical bone defect is a prerequisite for ingrowth of osteogenic reparative cells to regenerate bone, since lack of vessels does not ensure a sufficient nutritional support of the bone graft. The innovation of this study was to investigate the direct and indirect effects of endothelial progenitor cells (EPCs) and cotransplanted mesenchymal stem cells (MSCs) on the in vivo neovascularization activity in a critical size defect at the early phase of endochondral ossification. Cultivated human EPCs and MSCs were loaded onto β-TCP in vitro. A critical-sized bone defect (5 mm) was created surgically in the femoral diaphysis of adult athymic rat and stabilized with an external fixateur. The bone defects were filled with β-TCP, MSCs seeded on β-TCP, EPCs seeded on β-TCP, and coculture of MSCs and EPCs seeded on β-TCP or autologous bone of rat. After 1 week, the rats were sacrificed. Using quantitative CD34 immunohistochemistry as well as qualitative analysis of vascularization (staining of MHC and VEGF) in decalcified serial sections were performed by means of an image analysis system. Fluorescence microscopy analyzed the direct effects and indirect effects of human implanted EPCs for vessel formation at bone regeneration site. Formation of a primitive vascular plexus was also detectable in the β-TCP, MSC, or autologous bone group, but on a significantly higher level if EPCs alone or combined with MSCs were transplanted. Moreover, highest amount of vascularization were detected when EPCs and MSCs together were implanted. Early vascularization is improved by transplanted EPCs, which formed new vessels directly. Indeed the indirect effect of EPCs to vascularization is much higher. Transplanted EPC release chemotactic factors (VEGF) to recruit EPCs of the host and stimulate vascularization in the bone defect. Transplantation of human EPCs displays a promising approach to improve early vascularization of a scaffold in a critical bone defect. Moreover, coculture of EPCs and MSCs demonstrate also a synergistic effect on new vessel formation and seems to be a potential osteogenic construct for in vivo application.

Abstract
UNLABELLED A multicenter analysis was conducted to evaluate the main prognostic factors driving survival after radioembolization using yttrium-90-labeled resin microspheres in patients with hepatocellular carcinoma at eight European centers. In total, 325 patients received a median activity of 1.6 GBq between September 2003 and December 2009, predominantly as whole-liver (45.2%) or right-lobe (38.5%) infusions. Typically, patients were Child-Pugh class A (82.5%), had underlying cirrhosis (78.5%), and had good Eastern Cooperative Oncology Group (ECOG) performance status (ECOG 0-1; 87.7%), but many had multinodular disease (75.9%) invading both lobes (53.1%) and/or portal vein occlusion (13.5% branch; 9.8% main). Over half had advanced Barcelona Clinic Liver Cancer (BCLC) staging (BCLC C, 56.3%) and one-quarter had intermediate staging (BCLC B, 26.8%). The median overall survival was 12.8 months (95% confidence interval, 10.9-15.7), which varied significantly by disease stage (BCLC A, 24.4 months [95% CI, 18.6-38.1 months]; BCLC B, 16.9 months [95% CI, 12.8-22.8 months]; BCLC C, 10.0 months [95% CI, 7.7-10.9 months]). Consistent with this finding , survival varied significantly by ECOG status, hepatic function (Child-Pugh class, ascites, and baseline total bilirubin), tumor burden (number of nodules, alpha-fetoprotein), and presence of extrahepatic disease. When considered within the framework of BCLC staging, variables reflecting tumor burden and liver function provided additional prognostic information. The most significant independent prognostic factors for survival upon multivariate analysis were ECOG status, tumor burden (nodules >5), international normalized ratio >1.2, and extrahepatic disease. Common adverse events were: fatigue, nausea/vomiting, and abdominal pain. Grade 3 or higher increases in bilirubin were reported in 5.8% of patients. All-cause mortality was 0.6% and 6.8% at 30 and 90 days, respectively. CONCLUSION This analysis provides robust evidence of the survival achieved with radioembolization, including those with advanced disease and few treatment options.

Abstract
UNLABELLED (99m)Tc-macroaggregated albumin ((99m)Tc-MAA) scanning precedes radioembolization of the liver to detect extrahepatic shunting to the lung or gastrointestinal tract. Despite strict preventive measures in the production of (99m)Tc-MAA and in scanning protocols, the images frequently show a gastric concentration of free (99m)Tc-pertechnetate, hindering accurate evaluation of the gastroduodenal region. Our aim was to evaluate whether oral administration of sodium perchlorate (NaClO(4)) before (99m)Tc-MAA scanning will improve its accuracy by blocking free (99m)Tc-pertechnetate gastric uptake. METHODS In 144 patients, 171 diagnostic hepatic angiograms combined with a (99m)Tc-MAA scan were performed; 86 angiograms were performed after oral administration of NaClO(4), and 85 were performed without this premedication. Clinical follow-up, esophagogastroduodenoscopy, and angiography served as reference standards. RESULTS (99m)Tc-MAA studies showed tracer uptake in the gastric region of 25 patients who did not receive NaClO(4). The uptake was interpreted as a free (99m)Tc-pertechnetate concentration in 21 studies and as a (99m)Tc-MAA accumulation in 4 studies. In 5 patients with a free (99m)Tc-pertechnetate concentration, aberrant vessels were detected in angiographic reexamination, and 3 patients developed gastrointestinal ulcer. In 7 studies, gastric findings viewed pretherapeutically as free (99m)Tc-pertechnetate were retrospectively classified as equivocal. Of the patients receiving NaClO(4), 2 showed gastric accumulation of (99m)Tc-MAA but no equivocal or free (99m)Tc-pertechnetate. Oral administration of NaClO(4) increased the negative predictive value and accuracy of the test concerning the detection of gastric perfusion from 68% and 69%, respectively, to 93% and 94%, respectively. CONCLUSION Oral administration of NaClO(4) before the test angiogram with (99m)Tc-MAA resulted in effective avoidance of free (99m)Tc-pertechnetate concentration and, consequently, of equivocal findings in the gastroduodenal region. This technique increased test accuracy and reporter confidence, saved time in reviewing the angiograms, and can improve treatment planning and reduce therapeutic side effects.

Abstract
The incidence of hepatocellular carcinoma (HCC) is worldwide sharply on the rise and patients with advanced disease carry a poor prognosis. HCC is the sixth most common cancer and the third leading cause of cancer associated deaths in the world. Intra-arterially administered (131)I-Lipiodol is selectively retained by hepatocellular carcinomas, and has been used as a vehicle for delivery of therapeutic agents to these tumours. In this review we focus on the therapeutic indications, usefulness and methods of treatment with 131-Iodine Lipiodol. The effectiveness of (131)I-Lipiodol treatment is proven both in the treatment of HCC with portal thrombosis and also as an adjuvant to surgery after the resection of HCCs. It is at least as effective as chemoembolization and is tolerated much better. Severe liver dysfunction represents theoretic contraindication for radioembolization as well as for TACE. In such cases (131)I-Lipiodol is an alternative therapy option especially in tumours smaller than 6cm.
