RESUMO

BACKGROUND: To evaluate the safety and effectiveness of a stepwise interventional strategy for the removal of adherent totally implanted central venous access port catheters, consisting of a guidewire support, antegrade coaxial separation, and retrograde coaxial separation with increasing technical complexity. METHODS: This study has a retrospective design. Thirty-two patients who had failed routine removal of the port catheter and were then transferred to interventional radiology between November 2017 and December 2023 were reviewed. The technical success and complication rates were recorded. RESULTS: All adherent catheters were successfully removed without catheter fragmentation, using guidewire support (n = 21), antegrade coaxial separation (n = 5), and retrograde coaxial separation (n = 6). The technical success rate was 100%, and no complications occurred. CONCLUSIONS: The proposed stepwise interventional strategy successfully removed adherent port catheters, with good safety and high effectiveness. It appeared to reduce the incidence of catheter fracture during the removal of adherent totally implantable central venous access port catheters.

RESUMO

BACKGROUND AND AIM: Baveno VII workshop recommends the use of preemptive TIPS (p-TIPS) in patients with cirrhosis and acute variceal bleeding (AVB) at high- risk of treatment failure. However, the criteria defining "high-risk" have low clinical accessibility or include subjective variables. We aimed to develop and externally validate a model for better identification of p-TIPS candidates. APPROACH AND RESULTS: The derivation cohort included 1554 patients with cirrhosis and AVB who were treated with endoscopy plus drug (n = 1264) or p-TIPS (n = 290) from 12 hospitals in China between 2010 and 2017. We first used competing risk regression to develop a score for predicting 6-week and 1-year mortality in patients treated with endoscopy plus drugs, which included age, albumin, bilirubin, international normalized ratio, white blood cell, creatinine, and sodium. The score was internally validated with the bootstrap method, which showed good discrimination (6 wk/1 y concordance-index: 0.766/0.740) and calibration, and outperformed other currently available models. In the second stage, the developed score was combined with treatment and their interaction term to predicate the treatment effect of p-TIPS (mortality risk difference between treatment groups) in the whole derivation cohort. The estimated treatment effect of p-TIPS varied substantially among patients. The prediction model had good discriminative ability (6 wk/1 y c -for-benefit: 0.696/0.665) and was well calibrated. These results were confirmed in the validation dataset of 445 patients with cirrhosis with AVB from 6 hospitals in China between 2017 and 2019 (6-wk/1-y c-for-benefit: 0.675/0.672). CONCLUSIONS: We developed and validated a clinical prediction model that can help to identify individuals who will benefit from p-TIPS, which may guide clinical decision-making.

RESUMO

PURPOSE: This study aimed to assess the safety, effectiveness, and feasibility of the Liverty™ transjugular intrahepatic portosystemic shunt (TIPS) access set, which has an ergonomic handle that allows for in situ cannula tip deflection and a distal steerable cannula angle, versus the COOK® Rosch-Uchida Transjugular Liver Access Set (RUPS-100) in healthy pigs. METHODS: Twelve pigs randomly underwent TIPS with the Liverty™ set or the RUPS-100 set. Three interventionalists performed 4 TIPS procedures, 2 with each set. The primary outcome was procedural success, defined as successful establishment of the intrahepatic portosystemic shunt and stent placement. RESULTS: The shunt was successfully established in 11 pigs. The procedural success was achieved in all 6 pigs in the Liverty™ group and 5 out of 6 pigs for the RUPS-100 group (Fisher exact test, P > 0.999). The mean duration of puncture was shorter in the Liverty™ group versus the RUPS-100 group (12.3 ± 4.5 min vs. 16.2 ± 8.5 min), but without significant statistical difference (two sample t test, P = 0.359). The cannula angle was adjusted 69% of passes in the Liverty™ group, which was significantly higher than that in the RUPS-100 group (12%, P = 0.004). Overall, the TIPS procedural performance was comparable between the groups. Both sets were safe. No intraabdominal hemorrhage, vascular injuries, tissue or organ injuries, porto-biliary fistula, biliary peritonitis, and infection or abscess occurred in either group. CONCLUSION: The Liverty™ set is safe and has similar procedural metrics to the COOK® RUPS-100 set. It allows in situ adjustment of the angle of the stiffening cannula without increasing procedure time and lessens the occurrences of periprocedural complications.

RESUMO

Budd-Chiari syndrome (BCS) is a rare condition characterized by hepatic venous outflow obstruction. Balloon angioplasty, with or without stenting, is the recommended first-line treatment modality in Asian countries. As a supplement to balloon angioplasty, expandable metallic Z-stent deployment can effectively improve long-term inferior vena cava (IVC) patency. Although stent placement is a standard and frequently performed treatment, very few IVC stent-related complications, such as stent fractures, have been reported. Here we present a case series and a comprehensive review of IVC stent fractures in patients with BCS. The most common characteristic of IVC stent fractures is a protrusion of the proximal segment of the IVC stent into the right atrium and its systolic and diastolic movements along with heart rhythms. Accurate stent deployment, large-diameter balloon dilation, patient breath-holding training, preferential selection of a triple stent, and the use of an internal jugular vein approach to stent deployment may ensure precise stent localization and avoid postoperative complications.

RESUMO

BACKGROUND AND AIM: Baveno VII workshop recommends management of acute variceal bleeding (AVB) in cirrhotic patients with nonmalignant portal vein thrombosis (PVT) should be performed according to the guidelines for patients without PVT. Nevertheless, whether PVT affects the outcome of patients with cirrhosis and AVB remains unclear. The aim of this study was to assess the clinical impact of PVT on the outcomes in the pre-emptive TIPSS eligible patients with cirrhosis and AVB. METHODS: From December 2010 to June 2016, 1219 consecutive cirrhotic patients admitted due to AVB with (n = 151; 12.4%) or without PVT (n = 1068; 87.6%), who received drug plus endoscopic treatment (a combination of vasoactive drugs, antibiotics, and endoscopic ligation for AVB, followed by beta-blockers plus variceal ligation for prevention of rebleeding) were retrospectively included. Fine and Gray competing risk regression models were taken to evaluate the impact of PVT on clinical outcomes after adjusting for potential confounders. RESULTS: During follow-up, 211 patients (17.3%) died, 490 (40.2%) experienced further bleeding, and 78 (6.4%) experienced new or worsening ascites within 1 year. Compared with those without PVT, patients with PVT had a similar risk of mortality (PVT vs no-PVT: 19.9% vs 16.7% at 1 year; adjusted HR 0.88, 95%CI 0.51-1.52, p = 0.653), further bleeding (47.0% vs 39.2% at 1 year, adjusted HR 1.19, 95% CI 0.92-1.53, p = 183), and new or worsening ascites (7.9% vs 9.6%, adjusted HR 0.70, 95% CI 0.39-1.28, p = 0.253) after adjusting for confounders in multivariable models. These findings were consistent across different relevant subgroups and confirmed by propensity score matching analysis. CONCLUSIONS: Our study showed no evidence that the PVT was associated with an improved or worsened outcome among cirrhotic patients with AVB who received standard treatment.

RESUMO

(1) Background: Hepatic venous occlusion type of Budd-Chiari syndrome (BCS-HV) and pyrrolizidine alkaloid-induced hepatic sinusoidal obstructive syndrome (PA-HSOS), share similar clinical features, and imaging findings, leading to misdiagnoses; (2) Methods: We retrospectively analyzed 139 patients with BCS-HV and 257 with PA-HSOS admitted to six university-affiliated hospitals. We contrasted the two groups by clinical manifestations, laboratory tests, and imaging features for the most valuable distinguishing indicators.; (3) Results: The mean patient age in BCS-HV is younger than that in PA-HSOS (p < 0.05). In BCS-HV, the prevalence of hepatic vein collateral circulation of hepatic veins, enlarged caudate lobe of the liver, and early liver enhancement nodules were 73.90%, 47.70%, and 8.46%, respectively; none of the PA-HSOS patients exhibited these features (p < 0.05). DUS showed that 86.29% (107/124) of patients with BCS-HV showed occlusion of the hepatic vein, while CT or MRI showed that only 4.55%(5/110) patients had this manifestation (p < 0.001). Collateral circulation of hepatic veins was visible in 70.97% (88/124) of BCS-HV patients on DUS, while only 4.55% (5/110) were visible on CT or MRI (p < 0.001); (4) Conclusions: In addition to an established history of PA-containing plant exposure, local hepatic vein stenosis and the presence of collateral circulation of hepatic veins are the most important differential imaging features of these two diseases. However, these important imaging features may be missed by enhanced CT or MRI, leading to an incorrect diagnosis.

RESUMO

Background & Aims: Among individuals with Child-Pugh B cirrhosis and acute variceal bleeding (AVB), the Baveno VII workshop recommended pre-emptive TIPS in those with a Child-Pugh score of 8-9 and active bleeding at initial endoscopy (Child B8-9 + AB criteria). Nevertheless, whether this criterion is superior to the CLIF-Consortium acute decompensation score (CLIF-C ADs) remains unclear. Methods: Data on 1,021 consecutive individuals with Child-Pugh B cirrhosis and AVB from 13 university hospitals in China who were treated with pre-emptive TIPS (n = 297) or drug plus endoscopic treatment (n = 724) between 2010 to 2019 were retrospectively analysed. A competing risk regression model was used to compare the outcomes between the two groups after adjusting for confounders. The concordance-statistic for benefit (c-for-benefit) was used to evaluate a models' ability to predict treatment benefit (risk difference between treatment groups). Results: Pre-emptive TIPS was associated with reduced mortality compared to drug plus endoscopic treatment (adjusted hazard ratio 0.62, 95% CI 0.44 to 0.88). A higher baseline CLIF-C AD score was associated with greater survival benefit (i.e., larger absolute mortality risk reduction). After adjusting for confounders, a survival benefit was observed in individuals with CLIF-C ADs ≥48 or Child-Pugh B8-9 with active bleeding, but not in those with CILF-C ADs <48, no active bleeding or Child-Pugh B7 with active bleeding. The c-for-benefit of CILF-C ADs for predicting survival benefit was higher than that of Child B8-9+AB criteria. Conclusions: In individuals with Child-Pugh B cirrhosis and AVB, CLIF-C ADs predicts survival benefit from pre-emptive TIPS and outperforms the Child B8-9+AB criteria. Prospective validation should be performed to confirm this result, especially for other aetiologies of cirrhosis. Impact and implications: In this study, among individuals with Child-Pugh B cirrhosis and acute variceal bleeding, the CLIF-Consortium acute decompensation (CLIF-C AD) score could predict the survival benefit from pre-emptive TIPS, with patients with higher CLIF-C AD scores benefiting more from pre-emptive TIPS. Furthermore, the CLIF-C AD score outperformed the Child B8-9 plus active bleeding criteria in terms of discriminating between those who obtained more benefit vs. less benefit from pre-emptive TIPS. Depending on prospective validation, the CLIF-C AD score could be used as the model of choice to determine who should undergo pre-emptive TIPS.

RESUMO

OBJECTIVES: To evaluate the safety of irreversible electroporation (IRE) on swine pancreatic tissue including its effects on peripancreatic vessels, bile ducts, and bowel. METHODS: Eighteen Yorkshire pigs underwent IRE ablation of the pancreas successfully and without clinical complications. Contrast-enhanced computed tomography angiography and laboratory studies before the IRE ablation with follow-up computed tomography angiography, laboratory testing, and pathological examination up to 4 weeks postablation were performed. RESULTS: In a subset of cases, anatomic peripancreatic vessel narrowing was seen by 1 week postablation, persisting at 4 weeks postablation, without apparent functional impairment of blood flow. Laboratory studies revealed elevated amylase and lipase at 24 hours post-IRE, suggestive of acute pancreatitis, which normalized by 4 weeks post-IRE. There was extensive pancreatic tissue damage 24 hours after IRE with infiltration of immune cells, which was gradually replaced by fibrotic tissue. Ductal regeneration without loss of pancreatic acinar tissue and glandular function was observed at 1 and 4 weeks postablation. CONCLUSIONS: In our study, we demonstrated and confirmed the safety and minimal complications of IRE ablation in the pancreas and its surrounding vital structures. These results show the potential of IRE as an alternative treatment modality in patients with pancreatic cancer, especially those with locally advanced disease.

RESUMO

Gastric varices are a major complication of portal hypertension in patients with liver cirrhosis and are associated with more massive bleeding events and higher mortality rate. Transjugular intrahepatic portosystemic shunt (TIPS) and balloon-occluded retrograde transvenous obliteration (BRTO) have been well documented as effective therapies for portal hypertensive gastric variceal bleeding. In China, TIPS are well accepted but BRTO is not well recieved due to the increase risk of complications associated with traditional BRTO. However, modified-BRTO, known as coil-assisted and plug-assisted retrograde transvenous obliteration (CARTO and PARTO, respectively), is receiving increased attention due to devoid of BRTO's shortcomings. No CARTO case from China has been reported in literature thus far. Here, we present a Chinese case of CARTO to treat gastric varices bleeding.

RESUMO

Background: The purpose of this study is to describe a single institution's experience using Oncozene (OZ) microspheres for transarterial chemoembolization (OZ-TACE) of hepatocellular carcinoma (HCC), and to compare tolerability, safety, short-term radiographic tumor response, progression-free survival (PFS), and overall survival (OS) of these procedures to TACE (LC-TACE) performed with LC beads (LC). Methods: A retrospective, matched cohort study of patients undergoing DEB-TACE (drug-eluting bead transarterial chemoembolization) with OZ or LC was performed. The cohort comprised 23 patients undergoing 29 TACE with 75 or 100 µm OZ and 24 patients undergoing 29 TACE with 100-300 µm LC. Outcome measures were changes in liver function tests, complications, treatment tolerability, short-term radiographic tumor response according to modified RECIST criteria for HCC, PFS, and 1-year OS. The Mann-Whitney U test, Fisher exact test, and log rank test were used to compare the groups. Results: The BCLC or Child-Pugh scores were similar between the OZ and LC group. However, the two groups differed with respect to the etiology of background cirrhosis (p = 0.02). All other initial demographic and tumor characteristics were similar between the two groups. OZ-TACE used less doxorubicin per treatment compared to LC-TACE (median 50 vs. 75 mg; p = 0.0005). Rates of pain, nausea, and postembolization syndrome were similar, irrespective of the embolic agent used. OZ-TACE resulted in an overall complication rate comparable to LC-TACE (20.7% vs. 10.3%; p = 0.47). LC-TACE resulted in a higher percent increase in total bilirubin on post-procedure day 1 (median 18.8 vs. 0%; p = 0.05), but this difference resolved at 1 month. Both OZ-TACE and LC-TACE resulted in similar complete (31% vs. 24%) and objective (66% vs. 79%) target lesion response rates on 1-month post-TACE imaging. Both OZ-TACE and LC-TACE had similar median progression-free survival (283 vs. 209 days; p = 0.14) and 1-year overall survival rates (85% vs. 76%; p = 0.30). Conclusion: With a significantly reduced dose of doxorubicin, TACE performed with Oncozene microspheres in a heterogeneous patient population is well-tolerated, safe, and produces a similar radiological response and survival rate when compared to LC Bead TACE.

RESUMO

A 64-year old man had developed a giant mediastinal lymphocele after undergoing esophagectomy for the treatment of esophageal squamous cell carcinoma. The thoracic duct was embolized with six micro-coils, followed by embolization using a 1:3 mixture of N-butyl-2-cyanoacrylate (Histoacryl; B. Braun, Melsungen, Germany) and ethiodized oil. Resolution of the lymphocele was achieved within 5 days after embolization. To the best of our knowledge, ours is the first reported case of thoracic duct embolization for the treatment of mediastinal lymphocele.

RESUMO

INTRODUCTION: The purpose of this study was to investigate the rates of complications and diagnostic yield of transjugular liver biopsy (TJLB) in deceased donor liver transplant (DDLT) recipients. METHODS: From January 2009 to December 2019, 1,055 TJLBs were performed in 603 adult DDLT recipients with a mean age of 54 (±12 years). Data were retrospectively reviewed to determine the diagnostic efficacy and incidence of major and minor complications in the 3-day and 1-month period after TJLB. In addition, data were stratified according to platelet count and international normalized ratio to determine the safety of TJLB in patients with varying degrees of coagulopathy. RESULTS: TJLB yielded diagnostic rate of 98.1% (1,035/1,055), with an overall complication rate of 8.3% (88/1,055). Major complications accounted for 0.85% (9/1,055), and minor complications occurred in 7.48% (79/1,055). When patients were stratified by platelet count (0-50, 51-100, 101-200, 201-300, and >300 × 103 platelets/µL), no significant difference was noted in complication rates (9.5%, 8.6%, 7.6%, 8.5%, and 10.7%, respectively). When grouped by international normalized ratio (0-1, 1.1-2.0, 2.1-3.0, and >3.0), there was no statistical difference in complication rates (8.3%, 8.5%, 7.7%, and 0%, respectively). DISCUSSION: TJLB is a safe, adequate, and effective method to investigate hepatic disorders in DDLT recipients with severe coagulopathy.

RESUMO

BACKGROUND AND AIMS: Optimal candidates for early transjugular intrahepatic portosystemic shunt (TIPS) in patients with Child-Pugh B cirrhosis and acute variceal bleeding (AVB) remain unclear. This study aimed to test the hypothesis that risk stratification using the Chronic Liver Failure Consortium Acute Decompensation score (CLIF-C ADs) may be useful to identify a subgroup at high risk of mortality or further bleeding that may benefit from early TIPS in patients with Child-Pugh B cirrhosis and AVB. APPROACH AND RESULTS: We analyzed the pooled individual data from two previous studies of 608 patients with Child-Pugh B cirrhosis and AVB who received standard treatment between 2010 and 2017 in China. The concordance index values of CLIF-C ADs for 6-week and 1-year mortality (0.715 and 0.708) were significantly better than those of active bleeding at endoscopy (0.633 [P < 0.001] and 0.556 [P < 0.001]) and other prognostic models. With X-tile software identifying an optimal cutoff value, patients were categorized as low risk (CLIF-C ADs <48), intermediate risk (CLIF-C ADs 48-56), and high risk (CLIF-C ADs >56), with a 5.6%, 16.8%, and 25.4% risk of 6-week death, respectively. Nevertheless, the performance of CLIF-C ADs for predicting a composite endpoint of 6-week death or further bleeding was not satisfactory (area under the receiver operating characteristics curve [AUC], 0.588). A nomogram incorporating components of CLIF-C ADs and albumin, platelet, active bleeding, and ascites significantly improved the prediction accuracy (AUC, 0.725). CONCLUSIONS: In patients with Child-Pugh B cirrhosis and AVB, risk stratification using CLIF-C ADs identifies a subgroup with high risk of death that may derive survival benefit from early TIPS. With improved prediction accuracy for 6-week death or further bleeding, the data-driven nomogram may help to stratify patients in randomized trials. Future external validation of these findings in patients with different etiologies is required.

RESUMO

Budd-Chiari syndrome (BCS) is an uncommon disorder defined as an obstruction of the hepatic venous outflow. Percutaneous transluminal balloon angioplasty is a less invasive treatment option for BCS patients. However, there are no reports regarding inferior vena cava (IVC) rupture caused by perforation route through a collateral vein during treatment of BCS. Here, we report a male patient with BCS who had a long segmental obstruction of the IVC and its collateral vessels. Here, IVC rupture occurred at the distal end of the obstructed IVC during a percutaneous angioplasty; the rupture was repaired successfully with an endovascular stent graft.

RESUMO

Budd-Chiari syndrome (BCS) is a rare disease characterized by the obstruction of hepatic venous outflow due to occlusion of the hepatic vein (HV) or the inferior vena cava (IVC). The pathophysiology of IVC and HV membranous transformation, which can form in isolation or simultaneously, remains unclear in patients with combined-type BCS. Here we report three cases of patients with BCS demonstrating conversion from HV-type to combined-type. Three patients with only HV-type BCS underwent percutaneous balloon angioplasty (PTA) of the obstructed HV. During follow up, membranous transformation of the IVC was observed. This condition was subsequently treated with PTA of the IVC. These cases demonstrate that HV-type BCS may convert to combined-type BCS.

RESUMO

OBJECTIVE: Percutaneous transluminal balloon angioplasty (PTA) is the main treatment option for Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) obstruction. However, IVC rupture caused by PTA has never been reported. MATERIALS AND METHODS: Between August 2004 and December 2016, a consecutive cohort of 617 BCS patients with obstructed IVC who underwent PTA with or without stent placement were reviewed retrospectively to identify IVC rupture. Pre- and post-procedural imaging data, clinical and procedural technical data were analyzed. RESULTS: Of the 617 BCS patients, five patients had IVC rupture caused by PTA (0.81%). Four of these patients had retroperitoneal, intra-hepatic IVC rupture without extravasation into abdominal cavity which was successfully managed conservatively. One patient had supra-hepatic IVC rupture into the pericardial cavity which was surgically treated. CONCLUSION: IVC rupture is a rare complication of PTA treatment of BCS and most commonly located at the intra-hepatic IVC caused by oversized balloons which does not require additional treatment.

RESUMO

Budd-Chiari syndrome (BCS) is a heterogeneous group of disorders characterized by hepatic venous outflow obstruction. Abernethy malformation is a congenital vascular malformation defined by diversion of portal blood away from the liver. Both conditions are rare vascular diseases. We report here the first case of a patient with combined type II Abernethy malformation and BCS from China. The inferior vena cava obstruction was treated with percutaneous balloon angioplasty; close follow-up was elected for the Abernethy malformation.

RESUMO

AIM: To evaluate individualized treatment strategy (ITS) and long-term outcomes of endovascular treatment of Budd-Chiari syndrome (BCS) with obstructed inferior vena cava (IVC) based on different degrees of hepatic vein (HV) involvement. METHODS: From January 2006 to June 2017, 456 consecutive patients with BCS with obstructed IVC underwent endovascular treatment with ITS. All patients received IVC recanalization. Then, 426 patients with at least one patent HV received no additional treatment. Twenty-fivepatients with membranous or segmental occlusion of HVs underwent HV recanalization and for the remaining five patients with diffuse HVs occlusion, a transjugular intrahepatic portosystemic shunt (TIPS) was performed. RESULTS: The endovascular treatment was technically successful in 455 of the 456 patients (99.8%). The complication rate was 5.0% (23/456), with major complications in 13 patients (2.8%) and minor complications in 10 patients (2.2%). Median follow-up time was 60.5 months (range, 4-120 months). The cumulative 1-, 2-, 5- and 10-year primary vessel patency rates were 93.6%, 89.9%, 80.5% and 74.3% respectively and the cumulative 1-, 2-, 5-, 10- year secondary patency rates were 99.8%, 99.8%, 98.2% and 97.2% respectively. The cumulative 1-, 2-, 5- and 10-year survival rates were 98.4%, 95.8%, 91.2% and 76.5% respectively. Illness duration and decreased serum albumin were independent predictors of survival. CONCLUSION: The ITS for Asian BCS with obstructed IVC and varying degrees of HV involvement appears to be effective and with good long-term outcomes.
