To prospectively evaluate the use of a recently developed expanded polytetrafluoroethylene (PTFE)-covered nitinol stent-graft in preventing the need for repeated intervention after transjugular intrahepatic portosystemic shunt (TIPS) creation.Fifty-three consecutive patients underwent TIPS procedures between January 2000 and February 2002. Minimum patient follow-up was 9 months (mean, 16.3 months). Fifty-six stent-grafts were implanted in 53 patients; eight of the devices were 8 mm in diameter and 48 were 10 mm in diameter. The stent length varied from 4 to 7 cm. Indications for the procedure included recurrence of bleeding after sclerotherapy (28 patients with cirrhosis, one patient without), refractory ascites or hydrothorax (21 patients with cirrhosis, one patient without), and Budd-Chiari syndrome (two patients).A technical success rate of 100% was obtained, with an early clinical success rate of 96.2%. During the follow-up period, the recurrence rate was 3.4% (one of 29 patients) for bleeding and 9.0% (two of 22 patients) for ascites. Shunt malfunction occurred in nine of 53 patients (16.9%); in one of these nine patients, shunt occlusion was evident after revision, and a parallel shunt was created. The 1-year primary and secondary patency rates were 83.8% and 98.1%, respectively. In this series, the incidence of encephalopathy (included even as a single short-lived episode) was 47.1% (25 of 53 patients). The 30-day mortality rate was 3.8% (two of 53), and the late mortality rate was 17.3% (eight of 46), excluding seven patients who underwent transplantation.The new PTFE-covered nitinol stent-graft used appears to be excellent in preventing the need for repeated interventions. A primary patency rate of 83.8% and a secondary patency rate of 98.1% were achieved.

Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) by endografting is an increasingly common procedure. The enthusiasm for this technique is due to a hypothetical lower incidence of mortality, mainly in poor-risk patients, a shorter hospital stay and reduced costs when compared to open surgery. The more patients that have been treated, the longer the follow-up interval becomes and the more likely the appearance of complications. We describe here a case of aorto-enteric fistula appearing 22 months after the implantation of an endovascular graft (Vanguard II) for AAA.

PURPOSE To determine the technical efficacy and safety of an expanded polytetrafluoroethylene and fluorinated ethylene propylene (ePTFE/FEP)–covered metallic stent in the management of malignant biliary obstruction and to evaluate its clinical efficacy by estimating stent patency and patient survival rates. MATERIALS AND METHODS Twenty-six patients with common bile duct stricture caused by malignant disease were treated by placement of 29 stents. The stent consists of an inner ePTFE/FEP lining and an outer supporting structure of nitinol wire. Multiple wire sections elevated from the external surface provide anchoring. Stents are available in two versions, with or without holes in the proximal stent lining. Holes should provide drainage of the cystic duct or biliary side branches when covered by the proximal stent end. Clinical evaluation and assessment of serum bilirubin and liver enzyme levels were done before stent placement and at 1, 3, 6, and 9 months. Average follow-up duration was 5.4 months (range, 5dto 12.5 mo). RESULTS Placement was successful in all cases. The 30-day mortality rate was 11.5%. The survival rates were 40% and 15% at 6 and 12 months, respectively. Eighty-four percent of patients had adequate palliative drainage during their lifetime. The stent patency rates were 91%, 77%, and 77% at 3, 6, and 12 months, respectively. Four patients (16%) presented with stent occlusion and needed repeat intervention. No migration occurred. Complications other than stent occlusion occurred in five patients (19%); among these, acute cholecystitis was observed in three patients (12%). CONCLUSION Preliminary results suggest that placement of this ePTFE/FEP–covered stent is feasible and effective in achieving biliary drainage. The percentage of patients undergoing lifetime palliation and the midterm patency are promising. However, the incidence of acute cholecystitis is high. Treatment of a larger group of patients is mandatory to validate these long-term results.

The purpose of this study was to assess the accuracy of magnetic resonance imaging (MRI) in evaluating Crohn disease (CD) activity. The intestinal inflammatory activity is usually present in patients under pharmacologic treatment, despite their clinical remission.Twenty patients with CD, all under pharmacologic treatment, were prospectively studied by MRI at 1.5 T as a periodic control. Positivity of three acute-phase reactants was considered an index of biologic activity (BA). T2-weighted, T2-weighted fat-suppressed turbo spin-echo, and breath-hold T1-weighted turbo field-echo sequences, before and after gadolinium intravenous injection, were obtained. A negative superparamagnetic contrast agent was orally administered. The following MRI parameters were qualitatively evaluated by three radiologists at the level of the affected bowel and compared with clinical data: wall thickness (WT), wall T2-weighted signal (T2W), wall contrast enhancement (WE), amount of fibrofatty proliferation (FP), and T2-weighted signal of fibrofatty proliferation on fat-suppressed images (T2FP). The kappa coefficient of agreement was calculated. The Spearman rank correlation was used for the analysis of clinical and radiologic data.Nineteen of 20 patients were in clinical remission (Crohn Disease Activity Index150). On the basis of laboratory tests, nine of 20 patients had biologically active disease. An excellent correlation was found between BA and WE, T2W, and T2FP (0.900, 0.927 and 0.961, respectively; p0.0001), and a lower correlation was found between BA and WT and between BA and FP (0.78 and 0.62). Excellent statistical correlation was also found between WE and T2W and between WE and T2FP (0.876 and 0.892).An excellent statistical correlation was found between biologically "active" disease and the following MRI parameters: wall gadolinium enhancement, wall hyperintensity on T2-weighted fat-suppressed images, and hyperintensity of fibrofatty proliferation on T2-weighted fat-suppressed images. Therefore, MRI can be valuable in assessing CD activity.

Purpose: To report the risk of fatal atrial migration with the Tempofilter. Methods: Among temporary filters, the high safety profile Tempofilter has been marketed as offering protection for up to 6 weeks. We implanted about 60 Tempofilters to prevent pulmonary embolism. The main indications were temporary thromboembolic risk, recurrent pulmonary embolism, and contraindication to or failure of anticoagulant therapy. Follow-up was performed regularly by plain abdominal film and Doppler ultrasound. Filters were removed about 4 weeks after placement. Results: We encountered three cases (5%) of atrial migration and one case of 5-cm cephalad displacement of the filter. Of the three patients with atrial migration, two died within 3 days of implantation, one from a massive pulmonary embolism and the other with cardiac tamponade. One patient did not show any serious complications. Conclusions: The Tempofilter may actively migrate cranially and become dangerous in the case of migration within the heart.

Adventitial cystic disease of the popliteal artery is an unusual condition of uncertain etiology, in which a mucin-containing cyst forms in the wall of the artery and produces lower extremity claudication, typically in young and middle-aged men. A diagnosis of adventitial cystic disease of the popliteal artery was made preoperatively in a 47-year-old man by means of several imaging modalities, including angiography, magnetic resonance imaging, and ultrasound. The pathological findings confirmed the suggested diagnosis.

Arteriovenous malformations (AVM) are rare vascular lesions that can present with a myriad of clinical presentations. In our institutions, initial workup consists of a clinical exam, color Doppler imaging, and magnetic resonance imaging. After the initial nonivasive workup, arteriography, at times closed system venography, and ethanol endovascular repair of the AVM is performed under general anesthesia. Depending on the size of the lesion, additional Swan-Ganz line and arterial line monitoring are performed. Patients are usuallay observed overnight and uneventfully discharged the following day if no complication occurs. Patients are followed at periodic intervals despite cure of their lesion. Long-term follow-up is essential in AVM management.

We used an improved method for preparation of the intercostal pedicle flap for encircling bronchial anastomoses, and we studied its vascular supply after the operation. The flap was used in 56 patients undergoing various types of sleeve resection and in three patients undergoing single lung transplantation. The technique is simple, fast, and causes neither extra surgical trauma nor complications. It allows satisfactory isolation and sealing of the bronchial anastomosis. Even if complete anastomotic dehiscence occurs (one cased the flap preserves the continuity of the airway, thus avoiding bronchopleural fistulas or other complications. The postoperative arteriographic study of the intercostal artery supplying the flap (performed in 14 patients) demonstrated the full patency of the vessel in all cases. It also showed that a fine vascular network develops around the anastomosis early in the postoperative period.

In this retrospective multicenter study, the authors analyzed the clinical efficacy of different metallic stents in the palliative treatment of patients with neoplastic obstructive jaundice.Two hundred forty patients were treated in four European centers. Causes of obstruction were pancreatic carcinoma (n = 84), biliary neoplasm (n = 99), metastases in hilar nodes (n = 34), primary or secondary liver tumors (n = 4), and other tumors (n = 19). A total of 388 metallic stents were used: 300 Wallstents, 35 nitinol Strecker stents, 40 Gianturco-Rosch Z stents, and 13 tantalum Strecker stents.Overall 25- and 50-week survival rates were 42% and 16%, respectively; the 30-day mortality rate was 14.6%. Two deaths were related to the procedure (0.8%); 19 patients (8%) had major complications. The 25-week patency rate was significantly higher for the nitinol Strecker stents and the Wallstents (78% and 67%, respectively) than for the Z stents and the tantalum Strecker stents (30% and 20%, respectively) (P.01 and P.001, respectively). Average patency was 8.3, 5.9, 2.3, and 4.0 months, respectively. Reintervention due to stent obstruction was necessary in 53 patients.The Wallstent and the nitinol Strecker stents were the most effective in achieving long-term palliation. Patency was significantly affected by the level of obstruction but not by the type of obstructing tumor.

Purpose Technical characteristics and clinical efficacy of a new metallic stent for the management of biliary obstruction were investigated in a clinical study. Patients and Methods From February 1991 to January 1993, 35 self-expandable, nickel-titanium alloy wire-mesh stents (diameter, 10 mm; length, 6 cm) were placed in 19 patients with obstructive jaundice due to cholangiocarcinoma ( n = 6), pancreatic carcinoma ( n = 5), lymph node metastasis to the liver hilum ( n = 5), gallbladder carcinoma ( n = 2), and intraductal papillary mucosal hyperplasia ( n = 1). Results Stent placement was successful in 18 of 19 patients. In one patient, stent dislodgment occurred after correct release; no other procedure-related complications or deaths occurred within 30 days following the procedure. Two (11%) of the remaining 18 patients are alive at 11 months; 16 (89%) died after a mean survival of 7.4 months. Two of three patients with stent obstruction underwent repeated intervention. Adequate palliation from jaundice was achieved without further intervention in 83% of cases. The mean stent patency was not less than 7 months. Conclusion Use of these metallic stents reestablished bile flow in the occluded biliary tree. Their efficacy and patency rate were also adequate.

Aims To evaluate the feasibility and efficacy of Transjugular intrahepatic portosystemic shunt (TIPS) in non-cirrhotic patients with symptomatic portal hypertension secondary to portal cavernoma. Methods Our cohort includes 13 consecutive patients. Eleven were considered for Transjugular intrahepatic portosystemic shunt placement for complications not manageable by medical/endoscopic treatment and two because of the need of oral anticoagulation in presence of high-risk varices. Expanded-polytetrafluoroethylene-covered stents were used in all. Results One of the 13 patients was excluded because of a thrombosis of the superior cava and jugular veins. In 10 patients, Transjugular intrahepatic portosystemic shunt was successfully implanted [83.3%; 95% confidence interval: 52–98%]. One patient had an early shunt dysfunction with recurrence of variceal bleeding which required an emergency surgical shunt. Late shunt dysfunction occurred in two patients, successfully treated with angioplasty and re-stenting. Two patients experienced an episode of encephalopathy. Conclusions Transjugular intrahepatic portosystemic shunt is feasible in most of the patients with portal cavernoma and should be considered in those with severe complications uncontrolled by conventional therapy. The use of Transjugular intrahepatic portosystemic shunt to achieve a lifelong anticoagulation therapy in selected patients with high-risk varices may be another possible indication. These patients should be referred to selected Units with large experience in Transjugular intrahepatic portosystemic shunt placement.

Multidetector computed tomography (MDCT) detects coronary artery disease. However, an overestimation of coronary artery stenosis and artifacts can prevent accurate identification of significant coronary narrowing. The combination of MDCT with coronary flow reserve (CFR), the hyperemic/baseline peak flow velocity ratio, measured by transthoracic Doppler echocardiography might be helpful. We studied 144 consecutive patients with CFR and quantitative coronary angiography, obtained using both MDCT and invasive coronary angiography (reference method). It was hypothesized that the CFR might provide an incremental value to MDCT in detecting significant (> or =70%) left anterior descending (LAD) coronary artery stenosis. A CFR cutoff of

The aim of this retrospective analysis was to assess the clinical consequences after intentional left subclavian artery (LSA) occlusion. Thirty-seven patients, 27 type B dissection and 10 thoracic aneurysm, with short proximal neck (less than 2 cm) underwent endovascular treatment with intentional exclusion of LSA origin. No immediate complications occurred. Mean arterial pressure gradient, between right and left arms, ranged from 15 to 45 mmHg. After a mean follow-up of 43.70 + or - 24.01 months, mild left arm symptoms secondary to flow reduction occurred in eight cases (21.6%) but only one required LSA transposition, after 8 months, for visual impairment. Type II endoleaks from excluded LSA occurred in 10 cases (27.0%): in seven patients, leaks were treated with coils and/or glue embolization; in one case, leak sealed spontaneously; one patient died before leak embolization could occur; one patient refused any further treatment. Intentional exclusion of the LSA may be justified when a longer proximal landing zone in the aortic arch is required.

To evaluate the efficacy and safety of an expanded polytetrafluoroethylene-fluorinated ethylene-propylene (ePTFE/FEP)-covered metallic stent in the management of malignant biliary obstruction. Eighty consecutive patients with malignant common bile duct strictures were treated by placement of 83 covered metallic stents. The stent-graft consists of an inner ePTFE/FEP lining and an outer supporting structure of nitinol wire. Clinical evaluation, assessment of serum bilirubin and liver enzyme levels were analyzed before biliary drainage, before stent-graft placement and during the follow-up period at 1, 3, 6, 9 and 12 months. Technical success was obtained in all cases. After a mean follow-up of 6.9+/-4.63 months, the 30-day mortality rate was 14.2%. Survival rates were 40% and 20.2% at 6 and 12 months, respectively. Stent-graft patency rates were 95.5%, 92.6% and 85.7% at 3, 6 and 12 months, respectively. Complications occurred in five patients (6.4%); among these, acute cholecystitis was observed in three patients (3.8%). A stent-graft occlusion rate of 9% was observed. The percentage of patients undergoing lifetime palliation (91%) and the midterm patency rate suggest that placement of this ePTFE/FEP-covered stent-graft is safe and highly effective in achieving biliary drainage in patients with malignant strictures of the common bile duct.

Self-expanding metallic stents of a modified Gianturco design were used to treat benign strictures of the biliary tree in 17 patients. Thirteen patients had undergone several unsuccessful surgical repairs, and four had not undergone surgery because of their clinical status. All patients had already undergone multiple percutaneous balloon dilations without success. Stents were placed percutaneously, through a transhepatic approach, without complications. Adequate caliber of the strictured segment, stable relief of symptoms, and normalization of liver function tests were achieved in 14 patients (82.4%). Partial primary success was obtained in one patient; initial success was achieved in two patients, but strictures recurred after 5 months. The average follow-up period was 8 months. Results suggest that placement of these stents might represent a permanent therapeutic solution for intractable recurrences. Extended follow-up and experimental studies to clarify long-term patency and biotolerance are needed.

To determine, by using multi-detector row helical computed tomography (CT), the added value of obtaining unenhanced and delayed phase scans in addition to biphasic (hepatic arterial and portal venous phases) scans in the detection of hepatocellular carcinoma (HCC) in patients with cirrhosis.Local ethical committee approval and patient consent were obtained. One hundred ninety-five patients (129 men, 66 women; mean age, 61 years; age range, 39-78 years) with 250 HCCs underwent multi-detector row helical CT of the liver. A quadruple-phase protocol that included unenhanced, hepatic arterial, portal venous, and delayed phases was performed. Analysis of images from hepatic arterial and portal venous phases combined, hepatic arterial and portal venous phases with the unenhanced phase, hepatic arterial and portal venous phases with the delayed phase, and all phases combined was performed separately by three independent radiologists. Relative sensitivity, positive predictive value, and area under the receiver operating characteristic curve (A(z)) were calculated for each reading session.Mean sensitivity and positive predictive values, respectively, for HCC detection were 88.8% (666 of 750 readings) and 97.8% (666 of 681 readings) for the combined hepatic arterial and portal venous phases, 89.2% (669 of 750 readings) and 97.8% (669 of 684 readings) for hepatic arterial and portal venous phases with the unenhanced phase, 92.8% (696 of 750 readings) and 97.3% (696 of 715 readings) for hepatic arterial and portal venous phases with the delayed phase, and 92.8% (696 of 750 readings) and 97.3% (696 of 715 readings) for all four phases combined. The reading sessions in which delayed phase images were available for interpretation showed significantly (P.05) superior sensitivity and A(z) values.Unenhanced phase images are not effective for HCC detection. Because of the significant increase in HCC detection, a delayed phase can be a useful adjunct to biphasic CT in patients at risk for developing HCC.

PURPOSE To report endovascular repair of bilateral internal carotid arteries (ICAs) in a youth following an accident. CASE REPORT A 17-year-old boy presented with dissection of both ICAs after a motorcycle accident. The lesions started 2 cm above the bifurcation and continued upward to the siphon, with normal flow into the circle of Willis. Surgical repair was excluded due to the critical clinical condition of the patient and owing to the anatomical extent of the dissection. Carotid Wallstent endoprostheses were deployed bilaterally to repair the dissected segments of the ICAs. After 13 months, the patient is in good health, with complete patency of both arteries. CONCLUSIONS The good result we experienced in this case indicates that stents may be a safe and effective treatment for traumatic bilateral carotid dissections. However, the long-term durability of these devices in a young patient remains to be determined.

Imaging of the cirrhotic patient is a very difficult task due to the several morphologic and structural alterations that occur in the hepatic parenchyma. The presence of areas of fibrosis and regenerative nodules, often associated with haemodynamic alterations due to the portal hypertension, can make the identification of hepatocellular carcinoma very difficult or, in many cases, simulate the presence of tumour. Despite the use of state-of-the-art equipment and optimised study protocols, computed tomography (CT) has poor sensitivity for the detection of hepatocellular carcinoma. The present article illustrates the spiral CT findings that most often can be found in the evaluation of cirrhotic patients. In particular, the authors illustrate the CT patterns of regenerative nodules, dysplastic nodules, hepatocellular carcinomas and of all lesions that may mimic hepatocellular carcinoma.

Polytetrafluoroethylene (PTFE)-covered stent grafts appear to have the potential to improve TIPS patency, but data available are few and controversial. The aim of this prospective nonrandomized trial was to assess TIPS safety and 1-yr patency with a new commercially available PTFE-covered stent graft in comparison with a group of historical controls treated with conventional stents.Between July 1992 and December 1999, 87 consecutive cirrhotics underwent TIPS with conventional stents, while from January 2000 to November 2001, 32 consecutive cirrhotics were treated with PTFE-covered stent grafts. All patients were followed by the same medical team according to a prospective protocol for a diagnostic work-up and a surveillance strategy.The two groups were comparable for age, sex, etiology, and severity of cirrhosis. The 1-yr probability of remaining free of shunt dysfunction tended to be higher in the covered stent group: 76.3% (95% CI = 58.7-93.9%) versus 57.5% (95% CI = 46.6-68.4%); log rank test: p = 0.055. However, stenoses inside the stent were significantly higher in patients with bare stents (88% vs 17%), while stenoses at the hepatic or portal vein were more frequent in PTFE-covered stent-graft group (50% vs 9% and 33% vs 3%, respectively), (chi2 = 15.42; df = 2.0; p = 0.0004). Stenoses inside the covered portion of the stent did not occur. One-year cumulative rebleeding, encephalopathy, and survival were similar.PTFE-covered stents are able to solve pseudointimal hyperplasia within the stent tract, but have a high incidence of hepatic or portal vein stenosis. Improvements in stent design and insertion techniques are necessary to fully achieve the potential benefit of this new device.

Purpose: To describe an extension of type B dissection into type A during endoluminal treatment of acute type B dissection. Case Report: A 57-year-old man with acute type B dissection underwent endovascular repair using 2 Excluder stent-grafts. Before releasing the second stent-graft, the patient complained of mild central chest pain, headache, and visual flashes, but no hemodynamic changes were noticed. An angiogram, performed soon afterwards, showed a retrograde extension of the dissection through the aortic arch involving both the left carotid artery and the ascending aorta. The procedure was completed, and the patient was transported to the operating room where the proximal ascending aorta was replaced. Spiral computed tomographic angiography performed 2 weeks after the procedure showed complete exclusion of the primary entry tear. At 6-month follow-up, the patient was asymptomatic; the left carotid artery dissection had disappeared. Conclusions: Endovascular repair of acute type B dissection is technically feasible, but longer experience will help prevent technical complications.

To evaluate whether the use of two arterial phase image acquisition series, when combined with portal venous phase imaging at multi-detector row helical computed tomography (CT), would be superior enough to use of a single arterial phase image acquisition series to warrant the increased radiation dose.Multi-detector row CT was performed in 77 patients with 140 foci of hepatocellular carcinoma (HCC). A triple-phase protocol that included an early arterial phase, a late arterial phase, and a portal venous phase was performed. Images were analyzed separately by three radiologists to document the presence and number of HCC nodules. Separate reading sessions were performed for images from the early arterial phase, images from the late arterial phase, images from both arterial phases combined, and images from all three phases. Sensitivity and positive predictive values were calculated for each reading session.The average sensitivity and positive predictive values, respectively, for the detection of HCC were 48.5% and 96.4% for early arterial phase images, 87.1% and 94.0% for late arterial phase images, 87.1% and 94.0% for images from both arterial phases, and 88.5% and 93.4% for images from all three phases. Analysis of images from both arterial phases together yielded no improvement in either sensitivity or positive predictive value compared with analysis of late arterial phase images alone. Analysis of the combination of late arterial and portal venous phase images resulted in the highest sensitivity value.The acquisition of images during two arterial contrast phases does not provide additional benefit over timed conventional biphasic CT technique.

Purpose: To report the endovascular treatment of an intrahepatic portosystemic venous shunt (IPSVS) using a tissue adhesive solution. Case Report: A 40-year-old woman without diagnosed liver disease presented for evaluation of vague abdominal pains. A latent portosystemic encephalopathy was diagnosed only during hospitalization, when ultrasound examination disclosed a venous-venous right hepatic communication. The patient was treated with selective percutaneous embolization using a tissue adhesive after blocking the lesion's venous inflow and outflow tracts. The result was excellent, and the patient recovered completely in a few days. After 5 months, the patient is asymptomatic and event-free. Conclusions: Large IPSVS may be successfully treated percutaneously using a tissue adhesive solution, avoiding a more invasive procedure.

To determine and present the initial technical and clinical results of using an expanded polytetrafluoroethylene-fluorinated ethylene propylene (ePTFE-FEP)-covered biliary endoprosthesis to treat malignant biliary obstruction.This prospective nonrandomized study included 42 patients with malignant obstruction of the common bile duct, common hepatic duct, and hilar confluence. Unilateral (n = 38) or bilateral (n = 4) bile duct drainage was performed by using fully covered endoprostheses with anchoring fins. To avoid branch duct blockage, endoprostheses with drainage holes at the proximal end were available. Procedure- and device-related complications were recorded. Patient survival and stent patency rates were calculated with Kaplan-Meier survival analysis. Mean follow-up bilirubin and alkaline phosphatase levels were calculated, and differences in means were evaluated with a paired t test.Successful deployment, correct positioning, and patency of the device were achieved in all patients. Procedure-related complications occurred in two (5%) patients. Thirty-day mortality rate was 20% (eight of 41 patients), and median survival time was 146 days. Laboratory values decreased significantly after the procedure (P.001). Recurrent obstructive jaundice occurred in six (15%) patients. Primary patency rates at 3, 6, and 12 months were 90%, 76%, and 76%, respectively. Calculation of the composite end point of death or obstruction revealed a median patency duration of 138 days. No endoprosthesis migration was observed. Branch duct obstruction was observed in four (10%) patients. Postmortem examination of one stent revealed a widely patent endoprosthesis with intact covering.Initial results of percutaneous treatment of malignant biliary obstructions with fully covered ePTFE-FEP endoprostheses suggest that they are safe and potentially clinically effective.

Background/Aims : Patients undergoing transjugular intrahepatic portosystemic shunt (TIPS) are at risk of early death due to end-stage liver failure. The aim of this study was to compare model of end-stage liver disease (MELD) and Child–Pugh scores as predictors of survival after TIPS. Methods : We studied 140 cirrhotic patients treated with elective TIPS. Concordance (c)-statistic was used to assess the ability of MELD or Child–Pugh scores to predict 3-month survival. The prediction of overall survivals was estimated by comparing actuarial curves of subgroups of patients stratified according to either Child–Pugh scores or MELD risk scores. Results : During a median follow-up of 23.7 months, 55 patients died, 14 underwent liver transplantation and seven were lost to follow-up. For 3-month survival, the discrimination power of MELD score was superior to Child–Pugh score (0.84 vs. 0.70, z =2.07; P =0.038). Unlike Pugh score, MELD score identified two subgroups of Child C patients with different overall survivals ( P =0.027). The comparison between observed and predicted survivals showed that MELD score overrates death risk. Conclusions : MELD score is superior to Child–Pugh score as predictor of short-term outcome after TIPS. Its accuracy, however, decreases for long-term predictions.

IFX for remission 7 were still in remission, 5 restarted biologic therapy (3 Adalimumab, 2 IFX), 1 underwent ileal resection. No serious adverse events or malignancies were reported. Conclusions: In our cohort of IBD pts, IFX maintenance therapy was a durable and effective treatment over a 3-year period in children with CD, it appeared also an effective therapeutic option to avoid or postpone colectomy in UC pts.
