Abstract
Early HAT is the most frequent and severe vascular complication following liver transplantation. It is one of the major causes of graft failure and mortality. Endovascular thrombolytic treatment in patients with thrombotic complications after liver transplantation is an attractive alternative to open surgery as lower morbidity and mortality rates are reported for it. PTA following transcatheter thrombolysis has been successfully used to treat HAT in adults. To the best of our knowledge, there have not been any reports of a successful transcatheter thrombolysis using interventional radiological techniques in a patient only four months old. The present report describes the successful endovascular emergency treatment of a HAT three days after DD split liver transplantation.

Abstract
OBJECTIVE It was the aim of this study to evaluate a new infiltration score to determine the resectability of pancreatic carcinomas in preoperative planning. MATERIALS AND METHODS Eighty patients with suspected pancreatic tumor were examined prospectively using 16-row spiral CT. The scans were evaluated for the presence of pancreatic carcinoma, peripancreatic tumor extension and vascular invasion using a standardized questionnaire. Invasion of the surgically relevant vessels was evaluated using a new invasion score. The operative and histological findings and the clinical follow-up served as the gold standard. RESULTS Forty patients had a pancreatic carcinoma, 5 had metastasis of a different primary tumor, and in 35 patients, there was no malignant pancreatic disease. The sensitivity for tumor detection was 100%, with a specificity of 88% for differentiating between malignant and benign pancreatic tumors. Invasion of the surrounding vessels was evaluated correctly using the invasion score, with a sensitivity of 89% and a specificity of 99%. In evaluation of resectability, a sensitivity of 94% and a specificity of 89% were achieved. CONCLUSION Using 16-row spiral CT, the invasion score is a valid tool for correctly assessing invasion in relevant vessels in cases of pancreatic carcinoma and for determining resectability.

Abstract
AIM The purpose of this study was to evaluate the safety and efficacy of percutaneous transhepatic portal vein embolization of the right portal vein with an Ethibloc/Lipiodol mixture to induce hypertrophy of the left liver lobe in patients with primarily unresectable liver tumor. METHODS 15 patients (8 primary liver tumors, 7 liver metastases) underwent portal vein embolization. Liver volumetry, duration of hospitalization, complication rates, relevant laboratory values were documented. RESULTS In 13/15 patients (84.6%) embolization could be performed with a median of 8.8 ml (range 1.5-28 ml) Ethibloc/Lipiodol. One minor procedure-related complication (subcapsular hematoma) occurred, which did not affect the two-step liver resection. No patient developed acute liver failure after embolization or liver resection. The volume of the left liver lobe increased significantly (p = 0.0015) by 25% from a median of 750 ml (587-1,114 ml) to 967 ml (597-1,249 ml). 11/13 (81.8%) of the embolized patients underwent liver resection at a median of 49 days after embolization. Median hospitalization time was 4 days after embolization and 7 days after liver resection. Median overall survival of the 11 operated patients was 376 days. CONCLUSION Percutaneous transhepatic portal vein embolization using an Ethibloc/Lipiodol mixture is a safe, feasible, and efficient interventional procedure.

Abstract
PURPOSE To evaluate trisacryl-gelatin microspheres (40-120 microm) for acute and chronic tissue embolization in mini-pig livers. METHODS Thirteen animals were divided into four groups: group 1 (n = 3), total arterial bed occlusion with acute procedure; groups 2 to 4, chronic superselective embolization with follow-up of 1 week (group 2, n = 1), 4 weeks (group 3, n = 4) or 14 weeks (group 4, n = 5). Key endpoints were homogeneity and particle distribution in acute embolizations (group 1) and necrosis and inflammation in chronic embolizations (groups 2-4) as assessed microscopically and angiographically. RESULTS After liver embolization, parenchymal necrosis did not occur; only signs of vessel wall disintegration were evident. The bile ducts remained intact. A distinct foreign body reaction with sparse leukocytic infiltration and giant cells was found at 14 weeks, but no signs of major inflammation were found. Particles were seen at the presinusoidal level, but no particle transportation into the sinusoids was observed. CONCLUSIONS Embolization in mini-pig livers, using small trisacryl-gelatin microspheres, results in vessel fibrosis without parenchymal or bile duct necrosis. The most likely explanation for preservation of the parenchyma is portal inflow. Small trisacryl-gelatin microspheres may be ideal as an adjunct for chemoembolization.

Abstract
Acute gastrointestinal bleeding in patients with liver cirrhosis is associated with a high mortality. Ileal varices and collaterals from ectopic vessels are extremely rare, encountered in less than 5% of the cirrhotic patients. The diagnosis is frequently delayed because the regular diagnostic methods such as gastroscopy or colonoscopy are unsuccessful in accurate the source of bleeding in the majority of the cases. We report an unusual case of massive and uncontrollable lower intestinal bleeding from ileal varices with right ovarian vein anastomosis in a 56 year-old female patient with liver cirrhosis and previous history of abdominal and pelvic surgery. The accurate angiographic and computed tomography diagnosis allowed fast decompression of the portal venous system using a transjugular intrahepatic portosystemic shunt.

Abstract
PURPOSE Investigation of the hardware and image characteristics of a novel micro-CT system and evaluation of its potential to image animals and tissue samples. MATERIALS AND METHODS The scanner was characterized by phantom studies regarding image homogeneity, CT number stability, soft-tissue contrast, spatial resolution and X-ray dose. The phantoms used were specially designed to evaluate the imaging of mice and rats. Scans of hearts with coronary stents were performed and the tissue morphology and vascularization of tumor-bearing rodents were studied with dynamic contrast-enhanced (DCE) CT. RESULTS The CT numbers of the acrylic phantoms were reproducible with a 4 HU deviation. The inter-pixel deviation was low but depended on the scan mode. The correlation coefficient between CT number and iodine concentration (0 - 6000 HU) was 0.99. Single wires, lumen and endo-luminal plaques of heart stents were distinguishable. The density-time courses were reliably recorded and made it possible to distinguish the tumor and muscle tissue in DCE micro-CT scans CONCLUSION The novel micro-CT scanner is suitable for studying tissue densities and contrast agent kinetics.

Abstract
PURPOSE The purpose of this study was to evaluate the clinical long-term success of uterine artery embolization (UAE) in patients with symptomatic fibroids using spherical particles (Embosphere). MATERIALS AND METHODS 34 consecutive patients treated with UAE were initially enrolled in the study which had the following study goals 1) 1-year follow-up MRI evaluation of the fibroid behavior and 2) clinical long-term success due to standardized assessment of the main fibroid-related symptoms (hypermenorrhoea, dysmenorrhoea and dysuria) of the patients' individual overall health status and their therapy satisfaction at 1-year, 2- year and 3-year intervals after UAE. RESULTS Technical success was achieved in all procedures. Four patients had to be excluded from the long-term evaluation schedule: one because of a hysterectomy due to bleeding after 6 weeks, 3 patients were not available for the designated minimum follow-up interval. The preinterventional severe hypermenorrhoea (n = 27) with a score of 4.4 +/- 0.7 (5 = extreme menstrual bleeding) decreased after one year to 2.1 +/- 0.5 (p = 0.0001), after two years to 1.7 +/- 0.5 (p = 0.0042) and after three years to 1.3 +/- 0.6 (p = 0.0001). The preinterventional dysmenorrhoea (n = 15) with a score of 3.1 +/- 1.5 (3 = distinctly increased dysmenorrhoea) decreased after one year to 1.1 +/- 0.3 (p = 0.0001), after two years to 1.2 +/- 0.2 and after three years to 1.2 +/- 0.4 (p = 0.148). The pretreatment dysuria (n = 12) with a preinterventional score of 3.1 +/- 1.5 (3 = distinctly increased dysuria) decreased after one year to 1.1 +/- 0.3 (p = 0.0069) and remained after two years at 1.1 +/- 0.2 and after three years at 1.2 +/- 0.4 (p = 0.905). The initial overall health status was 54.7 +/- 20.1 (maximal value 100). After one year it rised to 90.5 +/- 15.4 (p = 0.0001), was 91.8 +/- 5.6 after two years and was 91.3 +/- 8.5 (p = 0.8578) after three years. The satisfaction with the therapy was 2.9 +/- 0.2 after one year, 2.6 +/- 0.3 after two years and 2.7 +/- 0.5 (3 = extremely satisfied) after three years. We observed 12 minor and 3 major complications (one hysterectomy, one fibroid expulsion associated with a short bleeding episode and one transient amenorrhoea for three months). All patients benefited clinically from the procedure and a clinical benefit was achieved in all cases. CONCLUSION Under controlled study conditions, flow-guided UAE with spherical embolization particles achieves high clinical success for all relevant clinical symptoms without negative changes during follow-up after at least 3 years. Accordingly, patient therapy satisfaction remained extraordinarily high even 3 years after UAE.

Abstract
INTRODUCTION Acute pancreatitis (AP) is a rare complication after liver embolization (LE) of primary and secondary liver tumors (approximately 1.7%), but it has a significant morbidity and mortality potential if associated with other complications. It usually develops early within 24 h after the LE procedure. STUDY PURPOSE To calculate the frequency of AP after LE in our institution and to analyze the factors involved in this procedure (anatomical features, embolization materials, cytostatic drugs, technical factors). MATERIALS AND METHODS 118 LE (bland embolization and transarterial chemoembolization) were performed in our institution. The study group included 59 patients who met the following inclusion criteria: one or more LE events, with complete pre- and post-interventional laboratory studies including: serum Ca(2+), creatinine, blood urea nitrogen, glucose, lactate dehydrogenase, aminotransferases, alkaline phosphatase, amylase, lipase, C-reactive protein, hematocrit and leukocytes. The diagnosis of AP was established according to the criteria of the Atlanta system of classification. For the statistical analysis the association between two response variables (e.g. AP after embolization and risk factor during the embolization, AP after embolization and volume of embolic material) was evaluated using Pearson's chi(2) test and Fisher's exact test. RESULTS The calculated frequency of AP after LE in our series was 15.2%. Amylase and lipase were elevated up to 8.7 and 20.1 times, respectively, 24 h after LE. We observed a statistically significantly lower incidence of AP in those patients who received 2 ml or less of embospheres compared with those with an embolization volume of >2 ml (Pearson's chi(2) = 4.5000, Pr = 0.034, Fisher's exact test = 0.040). Although carboplatin was administered to 7 of 9 of the patients who developed AP after the embolization procedure, there was no statistical significance (Fisher's exact test = 0.197) for carboplatin as an AP risk factor when compared with all the patients who received this drug (n = 107). CONCLUSION Although AP after LE seems to have a multifactorial etiology, both the toxicity of the antineoplastic drugs (carboplatin-related toxicity) as well as direct ischemic mechanisms (non-target embolization, reflux mechanisms) may be the most important causes of the inflammatory pancreatic reaction after LE. We suggest that systematic measurement of serum pancreatic enzymes should be performed in cases of abdominal pain following selective LE and transarterial chemoembolization in order to confirm acute pancreatitis after embolization, which can clinically mimic a postembolization syndrome.

Abstract
PURPOSE Using a pig model: (1) to evaluate the vascular distribution pattern, including the homogeneity and completeness of the intra-arterial microsphere distribution, of 40-120-microm trisacryl-gelatin microspheres (Embospheres) in acute whole-kidney embolization; (2) to evaluate the durability and biocompatibility of 40-120-microm trisacryl-gelatin microspheres (Embospheres) in chronic partial kidney embolization. METHODS Twenty-two animals were divided into four groups: group 1 (n = 4) underwent total arterial renal occlusion with immediate euthanasia. Groups 2-4 had chronic superselective and partial renal embolization with increasing follow-up times: group 2 (n = 2), 1 week; group 3 (n = 7), 4 weeks; and group 4 (n = 9), 14 weeks. Key endpoints in group 1 were homogeneity and completeness of acute embolizations. In groups 2-4 the key endpoints were durability of embolization and particle-related inflammation in chronic partial embolizations as assessed by quantitative angiography or histomorphometry. A numerical angiographic occlusion score (0.0 to 4.0, where 3.0 is optimal) was developed to assess and quantify the angiographic durability of superselective embolizations (groups 2-4). RESULTS In group 1, a relatively homogeneous distribution of the particles from segmental arteries to the precapillary level was shown by histomorphometry. Some particles reached the glomerular vas afferens (10 microm diameter). In groups 2-4, a mild recanalization appeared during follow-up. The immediate average postembolization occlusion score of 3.18 +/- 0.73 was reduced to 1.44 +/- 0.73 (statistically significant). Microscopy revealed subtotal necrosis but no foreign body granuloma formation. The intra-arterial appearance of giant cells closely attaching to the surface of the embolic spheres inside the vessel lumen was noted. Vessel walls showed major ischemic reactions. CONCLUSION Microspheres 40-120 microm in diameter might achieve total occlusion of the arterial kidney vasculature when injected centrally as a result of their fairly homogeneous distribution. Segmental renal infarction occurs after chronic partial embolization despite recanalizations during follow-up. Only mild specific intra-arterial foreign body reactions were found.
