Safety and effectiveness of transsplenic access for portal venous interventions: a single-center retrospective study. Abdom Radiol (NY) 2024; 49:2726-2736. [PMID: 38748092 DOI: 10.1007/s00261-024-04237-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/04/2024] [Accepted: 02/05/2024] [Indexed: 08/06/2024]
Abstract
PURPOSE To assess the safety and effectiveness of percutaneous transsplenic access (PTSA) for portal vein (PV) interventions among patients with PV disease. MATERIALS AND METHODS Adult patients with PV disease were enrolled if they required percutaneous catheterization for PV angioplasty, embolization, thrombectomy, variceal embolization, or transjugular intrahepatic portosystemic shunt (TIPS) placement for a difficult TIPS or recanalization of a chronically occluded PV. The procedures were performed between January 2018 and January 2023. Patients were excluded if they had an active infection, had a chronically occluded splenic vein malignant infiltration of the needle tract, had undergone splenectomy, or were under age 18 years. RESULTS Thirty patients (15 women, 15 men) were enrolled. Catheterization of the PV through PTSA succeeded for 29 of 30 patients (96.7%). The main adverse effect recorded was flank pain in 5 of 30 cases (16.7%). No bleeding events from the spleen, splenic vein, or percutaneous access point were recorded. Two cases (6.7%) each of hepatic bleeding and rethrombosis of the PV were reported, and a change in hemoglobin levels (mean [SD], - 0.5 [1.4] g/dL) was documented in 14 cases (46.7%). CONCLUSION PTSA as an approach to accessing the PV is secure and achievable, with minimal risk of complications. Minimal to no bleeding is possible by using tract closure methods.

Abstract
BACKGROUND Endovascular management of portal vein thrombosis (PVT) is challenging. Transsplenic access (TSA) is growing as an access option to the portal system but with higher rates of bleeding complications. The aim of this article is to evaluate the efficacy and safety of transsplenic portal vein recanalization (PVR) using a metallic stent after pediatric liver transplantation. MATERIALS AND METHODS This is a retrospective review of 15 patients with chronic PVT who underwent PVR via TSA between February 2016 and December 2020. Two children who had undergone catheterization of a mesenteric vein tributary by minilaparotomy were excluded from the patency analysis but included in the splenic access analysis. The technical and clinical success of PVR and complications related to the procedure via TSA were evaluated. RESULTS Thirteen children with PVT were treated primarily using the TSA. The mean age was 4.1 years (range, 1.5-13.7 years), and the most common clinical presentation was hypersplenism (60%). Technically successful PVR was performed in 11/13 (84.6%) children, and clinical success was achieved in 9/11 (81.8%) children. No major complications were observed, and one child presented moderate pain in the TSA (from a total of 17 TSA). The median follow-up was 48.2 months. The median primary patency was 9.9 months. Primary patency in the first 4 years was 75%, and primary assisted patency was 100% in the follow-up period. CONCLUSIONS Transsplenic PVR is a safe and effective method for the treatment of PVT after pediatric liver transplantation.

Abstract
OBJECTIVES Portal vein stenosis is a relatively rare complication after liver transplant but has severe consequences. We evaluated the efficacy and longterm results of the endovascular treatment methods for portal vein stenosis. MATERIALS AND METHODS From October 2011 to October 2022, we treated 22 patients (5 female, 17 male) with portal vein stenosis using endovascular methods. Doppler ultrasonography was used for initial diagnosis, with consideration of flow rate increase over stenosis, absence of flow, or reduced anastomotic segment size (>50%). Angiography served as the gold standard, with a pressure gradient above 5 mm Hg indicating the need for treatment. Technical success criteria were defined as <50% stenosis remaining and/or a pressure gradient <5mm Hg. The transhepatic approach was used for all patients. Balloon angioplasty was initially performed, and stents were reserved for patients in the early postoperative period or those unresponsive to balloon angioplasty. RESULTS The technical success rate was 100%. Mean age was 27.1 years (SD 22.4; range, 4 months to 63 years). Mean time from transplant to intervention was 317 days (range, 0-3135 days). Angioplasty was successful for 7 patients (13.8%). Of 15 patients who underwent stent placement, 9 (40.9%) were in the early postoperative period; in the other 6 patients (27%), results of angioplasty were not satisfactory, and stents were placed. Within 3 months of transplant, 3 patients died because of other complications. Among patients with stents, 2 required reintervention, resulting in reestablishment of good portal venous flow. During the mean follow-up of 24 months (range, 15 days to 9 years), 19 patients (86%) had portal flows within reference limits. CONCLUSIONS The endovascular approach is a safe and effective treatment option for management of portal vein stenosis in both adult and pediatric liver transplant recipients in the early or late period.

Abstract
BACKGROUND To assess the feasibility and safety of a gelfoam torpedo plugging technique for embolization of the transsplenic access channel in adult patients following transvenous portal vein interventions. MATERIALS AND METHODS Between 09/2016 and 08/2021, an ultrasound guided transsplenic portalvenous access (TSPVA) was established in twenty-four adult patients with a 21-G needle and 4-F microsheath under ultrasound guidance. Afterwards, sheaths ranging from 4-F to 8-F were inserted as needed for the procedure. Following portal vein intervention, the splenic access tract was embolized with a gelfoam-based tract plugging (GFTP) technique. TSPVA and GFTP were performed twice in two patients. Patients' pre-interventional and procedural characteristics were analyzed to assess the feasibility and safety of the plugging technique according Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification system. Values are given as median (minimum;maximum). Subgroup analysis of intercostal vs. subcostal puncture site for TSPVA was performed using the two-sided Mann-Whitney-U test or Student's t-test and Fisher's exact test. Level of significance was p < 0.05. RESULTS The study population's age was 56 (29;71) years and 54% were female patients. Primary liver disease was predominantly liver cirrhosis with 62% of the patients. Pre-interventional model for end-stage liver disease score was 9 (6;25), international normalized ratio was 1.15 (0.86;1.51), activated partial thromboplastin time was 33s (26s;52s) and platelet count was 88.000/µL (31.000;273.000/µL). Ascites was present in 76% of the cases. Craniocaudal spleen diameter was 17cm (10cm;25cm). Indication for TSPVA was assisted transjugular intrahepatic portosystemic shunt placement in 16 cases and revision in two cases, portal vein stent placement in five cases and variceal embolization in three cases. TSPVA was successfully established in all interventions; interventional success rate was 85% (22/26). The splenic access time was 33min (10min;133min) and the total procedure time was 208min (110min;429min). Splenic access was performed with a subcostal route in 11 interventions and with an intercostal route in 15 interventions. Final sheath size was 4-F in 17 cases, 5-F in three cases, 6-F in five cases, 7-F in two cases and 8-F in one case. A median of two gelfoam cubes was used for GFTP. TSPVA- and GFTP-related complications occurred in 4 of 26 interventions (15%) with a subcapsular hematoma of the spleen in two patients (CIRSE grade 1), access-related infection in one patient (CIRSE grade 3) and both in one patient (CIRSE grade 3). In detail, one access-related complication occurred in a patient with subcostal TSPVA (CIRSE grade 1 complication) and the other three complications occurred in patients with intercostal TSPVA (one CIRSE grade 1 complication and two CIRSE grade 3 complication) (p = 0.614). No patient required interventional or surgical treatment due to puncture tract bleeding. CONCLUSION Gelfoam-based plugging of the puncture tract was feasible and safe for transsplenic access in adult patients undergoing percutaneous portal vein interventions. The lack of major bleeding complications and complete absorption of the gelatine sponge make it a safe alternative to transjugular and transhepatic access and re-interventions via the splenic route.

Abstract
BACKGROUND Vascular complications after liver transplantation (LT) can be lethal and require immediate treatment to prevent graft failure. Nowadays, with interventional radiology (IR), approaches such as the percutaneous transhepatic (PTH) and transileocolic venous (TIC), have become major treatment options. We reviewed the safety and efficacy of a hybrid operating room (OR) for portal vein complications after LT. METHODS Patients who underwent IR for post-LT vascular complications in the hybrid OR from May 2014 to May 2022 were enrolled. Patients who underwent post-LT IR in conventional angiography rooms were excluded. RESULTS Nine patients developed portal vein complications; eight after living donor LT and one after deceased donor LT. Six patients had portal vein stenosis, two had portal vein thrombosis, and one had both. In the hybrid OR, PTH and TIC were used in five and three cases, respectively. The Rendezvous technique was used in one case. Angioplasty was performed in all patients. A stent was placed in four patients. The portal venous pressure gradient across the stenotic site significantly decreased after IR (P &= 0.031). The IR success rate in the hybrid OR was 100%. CONCLUSION The hybrid OR enables us to accomplish IR for post-LT vascular complications safely and effectively.

Abstract
BACKGROUND IPVS is considered a last resort or a salvage procedure in the event of recurrent PV thrombosis despite multiple attempts at redo PV anastomosis. We employed the opened umbilical vein approach to place the stent in the PV and deliver anticoagulation through a catheter. MATERIALS AND METHODS From Jan 2017 to Feb 2022, 150 patients underwent pediatric transplantation at department of liver transplant and hepatobiliary surgery unit, Indraprastha Apollo hospitals, New Delhi. Age, weight, PELD Score, diagnosis, portal vein diameter on preoperative CT, Portal flow after stenting, decrease in spleen size after stenting in follow-up CT were collected from a prospectively maintained data base and reviewed. RESULTS Eight patients underwent IPVS following LDLT (mean age-10.6 ± 2.2 months, mean weight 8.1 ± 1.6, mean PELD score 32.7 ± 7.3). The mean PV diameter on preoperative CT scan was 3.6 mm (range 2.7-5.6 mm). The mean portal flow following stenting was 718.75 cc/min. Percentage reduction in size of the spleen was 26.35% beyond 2nd post-operative week. No patient had recurrent PV thrombosis following IPVS and all maintained an adequate portal flow throughout the immediate postoperative period. Two patients had in-hospital mortality secondary to septic complications. CONCLUSION Umbilical vein approach is technically feasible, easy to manipulate the stent and catheter placement after stenting helps to deliver anticoagulants locally.

Abstract
Background Liver transplantation is considered to be the treatment of choice in cases of end-stage liver disease; however, as a major procedure, the operation is fraught with complications. The etiology, symptoms, and diagnostic methods for arterial, portal, and biliary issues are thoroughly discussed. Interventional procedures such as balloon angioplasty and stent placement in the arterial and portal systems, as well as biliary interventional procedures, are described.
Results In our study, we reviewed 25 cases of post-living donor transplanted liver, with anastomotic complications including biliary stenosis 40%, hepatic vein stenosis 20%, portal vein stenosis 16%, biliary leakage 16%, and hepatic artery stenosis or pseudo-aneurysm 16%. We had 10 cases of biliary stenosis, 7 of which were successfully treated with the insertion of an internal/external drain, and one case failed. Two patients died. We had four cases of hepatic venous obstruction with successfully implanted stents and a perfect outcome, efficacy, and patency rate of 100%. We also had two cases of hepatic artery stenosis that were perfectly managed by stent placement, with a patency rate of 100%. We came across two cases of hepatic artery pseudo-aneurysm. One case failed due to large sac size, while the other was successful. Finally, in our study, we had a 100% success rate in 5 cases of portal vein stenosis in the early postoperative period.
Conclusions Percutaneous IR was effective treatment for hepatic vein occlusion, portal vein stenosis, hepatic artery stenosis, and anastomotic biliary stricture after living donor liver transplantation. The interventional radiology team is now an integral part of the multi-disciplinary care of transplant patients. As new interventional instruments are developed and experience is gained, the outcomes of interventional treatments will continue to improve.

Abstract
PURPOSE To illustrate diagnostic and interventional imaging for the characterization and treatment of portal vein thrombosis (PVT). INTRODUCTION The broad spectrum of congenital and acquired PVT manifestations is illustrated, with a focus on the pediatric population; diagnostic and interventional imaging techniques are described. DESCRIPTION PVT frequently presents as an incidental finding at imaging in the screening for liver diseases or for other unrelated reasons. PVT can be classified based on: extension (intrahepatic, extrahepatic, involving the spleno-mesenteric tract, etc.); degree (partial or complete); onset (acute or chronic); and with or without cavernomatous transformation. This comprehensive review relies on the experience gained from a large series of congenital and acquired PVT in a referral center for pediatric and adult liver transplantation. Diagnostic and interventional imaging techniques are described, including: color-Doppler and contrast-enhanced Ultrasound; CT and MR angiography; retrograde portography; percutaneous transhepatic, transplenic, and transmesenteric portography; transjugular intrahepatic portosystemic shunt creation. Pre- and post-operative imaging assessment of the surgical meso-rex bypass is discussed. The description is enriched with an original series of pictorial imaging findings. CONCLUSION PVT is a clinical condition associated with significant morbidity and mortality. Diagnostic and interventional imaging plays a crucial role in both conservative and operative management.

Abstract
Patients with acute and chronic liver disease present with a wide range of disease states and severity that may require liver transplantation (LT). Physiologic alterations occur that are dynamic throughout all phases of perioperative care, creating complex management scenarios that necessitate multidisciplinary clinical care. Specifically, alterations in hemostasis in liver disease can be pronounced and evolve with disease progression over time. Recent studies and society guidance address this emerging paradigm and offer recommendations to assist with hemostatic management in patients with liver disease. However, patients undergoing LT are unique and diverse, often with unstable disease that requires specialized approaches. Our aim is to provide a focused review of hemostatic management of the LT patient, distinguish unique aspects of the three main phases of care (before LT, perioperative, and after LT), and identify knowledge gaps and critical areas of future research.

Long-term outcome of primary percutaneous stent angioplasty for pediatric posttransplantation portal vein stenosis. Liver Transpl 2022; 28:1463-1474. [PMID: 35447015 DOI: 10.1002/lt.26488] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 04/02/2022] [Accepted: 04/15/2022] [Indexed: 01/13/2023]
Abstract
This study aims to evaluate the long-term efficacy and reintervention rate after primary percutaneous portal vein stent angioplasty for portal vein stenosis (PVS) in pediatric liver transplantation (LT) recipients. From 2004 to 2020, a total of 470 pediatric LTs were performed in our center. All cases were screened for interventional PVS treatment and analyzed retrospectively. We identified 44 patients with 46 percutaneous angioplasties for posttransplantation PVS. The median interval from LT to percutaneous catheter intervention was 5 months (16 days-104 months) with a median follow-up (f/u) period after catheter intervention of 5.7 years (2-156 months). In 40 patients, an endovascular stent was placed as primary (n = 38) or secondary (n = 2) intervention. The median age at stent placement was 23 (6-179) months with a median weight of 10 kg (6-46 kg). Technical success and relief of PVS were achieved in all patients irrespective of age or weight. Adverse events occurred peri-interventionally in two patients and were resolved with standard care. All primary portal vein (PV) stents remained patent until the end of f/u. Reinterventions have been successfully performed in 10 patients for suspected or proven restenosis, resulting in a primary patency rate of 75% and an assisted patency rate of 25%. The median time to reintervention was 6.2 years (range 1-10 years). The need for reintervention was independent of age or weight at both transplantation and initial angioplasty as well as of additional risk factors due to portal hypertension. Percutaneous transhepatic PV stent angioplasty in children is safe and effective in all age groups, with excellent long-term patency. Primary stent angioplasty should be considered as first-line treatment for PVS after pediatric LT.

Abstract
Multiple diseases of the portal system require effective portal vein access for endovascular management. While percutaneous transhepatic and transjugular approaches remain the standard methods of portal vein access, transsplenic access (TSA) has gained recognition as an effective and safe technique to access the portal system in patients with contraindications to traditional approaches. Recently, the utility of percutaneous TSA has grown, with described treatments including recanalization of chronic portal vein occlusion, placement of stents for portal vein stenosis, portal vein embolization of the liver, embolization of gastric varices, placement of complicated transjugular intrahepatic portosystemic shunts, and interventions after liver transplant. The authors provide a review of percutaneous TSA, including indications, a summary of related portal vein diseases, and the different techniques used for access and closure. In addition, an imaging-based review of technical considerations of TSA interventions is presented, with a review of potential procedural complications. With technical success rates that mirror or rival the standard methods and reported low rates of major complications, TSA can be a safe and effective option in clinical scenarios where traditional approaches are not feasible. ©RSNA, 2022.

Radiol Case Rep 2022; 17:2603-2606. [PMID: 35663820 PMCID: PMC9157188 DOI: 10.1016/j.radcr.2022.04.025] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 04/13/2022] [Accepted: 04/13/2022] [Indexed: 01/10/2023] Open
Abstract
Portal vein recanalization-transjugular intrahepatic portosystemic shunt (PVR-TIPS) is a valuable technique in the treatment cirrhosis and portal vein (PV) thrombosis. Only a few studies have reported cases of utilizing the transmesenteric approach in the procedure's initial portal access. Here, we report the successful utilization of a CT-guided percutaneous puncture of the superior mesenteric vein (SMV) for PVR-TIPS in a patient with splenic vein thrombosis. A 54-year-old male with a history of morbid obesity (BMI: 44.67), hepatitis C, NASH cirrhosis, esophageal varices, and complete PV thrombosis presented for PVR-TIPS. An initial percutaneous transplenic approach was attempted, but was aborted due to the discovery of a splenic vein thrombosis. Subsequently, the patient was brought back into the hybrid-angio CT suite, and the SMV was accessed percutaneously with a 21-gauge needle under 4D CT-guidance. A 5-Fr micropuncture sheath was then placed. Additional portal venogram confirmed PV thrombosis. Right internal jugular vein (IJV) access was then obtained, and the right hepatic vein was catheterized. A loop snare was advanced from the SMV access into the right PV. A Colapinto needle was later positioned in the right hepatic vein, and the right PV was accessed using the loop snare as a target. A wire was then advanced and captured by the snare, and brought down through the PV. The tract was dilated with a 10 mm balloon, and a Viatorr stent was deployed. Balloon embolectomy of the SMV, splenomesenteric vein, and TIPS were then performed with a CODA balloon with improvement in flow through the TIPS on final portal venogram. Portosystemic gradient was 11 mmHg initially and 10 mmHg post-TIPS. Follow-up TIPS venogram in 3 weeks showed a widely patent TIPS. CT-guided percutaneous SMV access may serve as valuable technique in PVR-TIPS when traditional modes of initial portal access for recanalization are unobtainable.

Abstract
Cavernous transformation of the portal vein (CTPV) is a sequela of extrahepatic and/or intrahepatic portal vein obstruction caused by a combination of local and risk factors. It was ever taken as a relatively rare disease due to its scant literature, which was mainly based on clinical series and case reports. CTPV often manifests as gastroesophageal variceal bleeding, splenomegaly, and portal biliopathy after the long-term insidious presentation. It is unable for CTPV to be recanalized with anticoagulation because it is a complete obstruction of the mesentericoportal axis. Endoscopic therapy is mainly used for temporary hemostasis in acute variceal bleeding. Meso-Rex shunting characterized by portal-flow-preserving shunts has been widely performed in children with CTPV. The multitude of complications associated with CTPV in adults can be effectively addressed by various interventional vascular therapies. With the ubiquity of radiological examinations, optimal treatment for patients with CTPV becomes important. Multivisceral transplantation, such as liver-small intestinal transplantation, may be lifesaving and should be considered for patients with diffuse mesenteric venous thrombosis.

Abstract
PURPOSE OF THE SYSTEMATIC REVIEW To determine the efficacy and safety of percutaneous trans-hepatic balloon and/or stent angioplasty (PTA) in the management of portal vein (PV) stenosis following paediatric liver transplantation. METHODS Articles were included from a systematic search of Medline, Embase, Cochrane CENTRAL, ClinicalTrials.gov and International Clinical Trials Registry from inception to the 29th of August 2020. RESULTS There were 213 paediatric liver recipients who underwent PTA for PV stenosis in 19 included studies published between 1991 and 2019. Balloon angioplasty was the initial treatment in the majority (n = 153). Primary stent placement (n = 34) was performed for elastic recoil, intimal tears and PV kinks and rescue stent placement (n = 14) for recurrent PV stenosis following primary balloon angioplasty. The technical success was 97.6%-100% overall, 97.6%-100% for balloon-angioplasty-only and 100% for primary stenting. The clinical success was 50%-100% overall, 50%-100% for balloon-angioplasty-only and 100% for primary stenting. Long-term PV patency was 50%-100% overall, 37.5%-100% for balloon-angioplasty-only and 100% for primary stenting. Primary balloon angioplasty was successful in 78% of the cases. Of the recurrent PV stenoses, 9% resolved with stent placement and one required a meso-Rex shunt. There was one re-transplantation without stenting. The complication rate was 2.6% for balloon-angioplasty-only (bleeding, liver abscess, 2 PV thromboses) and 5.9% for primary stenting (bleeding, stent-fracture). There was no procedure-related mortality. CONCLUSION Percutaneous transhepatic balloon angioplasty may be the initial management of portal vein stenosis in paediatric liver recipients. Stent placement may be a primary option in selected cases and a reliable rescue option for recurrent portal vein stenosis following balloon-angioplasty-only.

Abstract
Objectives: Bleeding risk after percutaneous portal vein access procedures is not negligible. Various agents, coils and plug, have been used to minimize this risk, each with their own advantages and disadvantages. This study reports the results of coagulation using thermal-ablation (radiofrequency or microwave ablation) as an alternative to trans-hepatic puncture tract closure. Methods: Ten patients who benefited from portal vein recanalization or portal hypertension-relative bleeding complication embolization using percutaneous portal vein access and who underwent thermal-ablation of the puncture tract between December 30, 2019 and July 16, 2020 were included. Early efficiency and safety were evaluated using imaging (ultrasound and/or CT scan) and laboratory data (hemoglobin, hepatic function) at 24 h. Follow-up was performed until August 2020. Results: No bleeding from the puncture tract and no embolization-related complications were observed in all 10 patients at 24 h or during follow-up with median of 3 months (range 1–8 months), even in case of ascites or therapeutic coagulation. Conclusion: Thermal-ablation seems to be a safe, effective and rapid technique to avoid bleeding after percutaneous transhepatic direct portal vein access. Advances in knowledge: Thermal-ablation could be an alternative for transhepatic puncture tract closure especially for patients with high bleeding risk.

Abstract
Portal vein thrombosis (PVT) is an uncommon but serious complication after liver transplantation (LT). Treatments for PVT include thrombolysis, surgical treatment or percutaneous intervention. We here report a case of PVT after LT successfully treated by an AngioJet device using the percutaneous transhepatic approach. A 36-year-old male presented with substantial thrombosis of the portal vein/superior mesenteric vein 2 years after a liver transplant. He was managed with an Angiojet thrombectomy and subsequent stent placement. This approach may be a safe and effective treatment for PVT in post-orthotopic LT patients.

Abstract
PURPOSE The aim of this study was to compare the safety and efficacy of transhepatic puncture tract embolization with n-butyl cyanoacrylate (n-BCA) versus coils after percutaneous transhepatic portal vein interventions in patients with hepatocellular carcinoma (HCC). It was also the aim of the study to evaluate the extent of artifacts in CT exams during FU. METHODS Single-center retrospective study from 2017-2019 in 190 patients who underwent percutaneous transhepatic portal vein interventions. The transhepatic puncture tracts were embolized with n-BCA in 88 patients (Group A) and with coils in 102 patients (Group B). Procedure-related complications and image noise around coils and n-BCA were compared between the groups. No significant differences were noted at baseline between both groups (platelets, coagulation, liver disease, types of procedures, liver function, liver tumors). RESULTS All patients underwent transhepatic puncture tract embolization. Procedure-related complications were only observed in patients from Group B: subcapsular hemorrhage (n = 2; 1.96%), hepatic artery hemorrhage (n = 1; 0.98%), and pseudoaneurysms combined with hemobilia occurred (n = 1; 0.98%). In Group A, the distal part of the punctured portal vein branch was embolized with n-BCA in 1 patient (1.14%). Four major complications in Group B Vs 0 in Group A were observed, respectively (p < 0.0001). The image noise around n-BCA was significantly lower than that around coils (10.7 ± 1.7 HU vs. 54.3 ± 15.0 HU, p < .001). CONCLUSIONS n-BCA tract embolization is more effective than using coils, with fewer bleeding events, at the cost of a higher potential for unintended embolization of portal vein branches.

Portal Vein Complications After Adult Living Donor Liver Transplantation: Time of Onset and Deformity Patterns Affect Long-Term Outcomes. Liver Transpl 2021; 27:854-865. [PMID: 33346927 DOI: 10.1002/lt.25977] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Revised: 11/08/2020] [Accepted: 11/29/2020] [Indexed: 01/10/2023]
Abstract
Portal vein complications (PVCs) after adult living donor liver transplantation (LDLT) are potentially lethal. We categorized PVCs by the time of onset (early versus late, <1 month versus ≥1 month, respectively) and deformity patterns (portal vein stenosis [PVS], portal vein thrombosis [PVT], and portal vein occlusion [PVO]) to establish optimal treatment strategies. Overall, 35/322 (10.9%) recipients developed PVCs between 2000 and 2019. Pretransplant PVT (odds ratio [OR], 15.20; 95% confidence interval [CI], 3.70-62.40; P < 0.001) was the only independent risk factor for PVS. In contrast, male sex (OR, 5.57; 95% CI, 1.71-18.20; P = 0.004), pretransplant PVT (OR, 4.79; 95% CI, 1.64-14.00; P = 0.004), and splenectomy (OR, 3.24; 95% CI, 1.23-8.57; P = 0.018) were independent risk factors for PVT. PVS was successfully treated with interventional radiology regardless of its time of onset. On the other hand, late PVT and PVO had significantly lower treatment success rates (2/15, 13%) compared with those that occurred in the early period (10/11, 91%) despite aggressive intervention (P < 0.001). Deformity patterns had a significant impact on the 5-year cumulative incidence of graft loss as a result of PVC (PVO + Yerdel grades 2-4 PVT group [n = 16], 41% versus PVS + Yerdel grade 1 PVT group [n = 19], 0%; P = 0.02). In conclusion, late grades 2 to 4 PVT and PVO are refractory to treatment and associated with poor prognoses, whereas PVS has a good prognosis regardless of time of onset. A tailored approach according to the time of onset and deformity patterns of PVC is essential.

JMIR Med Inform 2021; 9:e27175. [PMID: 33999008 PMCID: PMC8167618 DOI: 10.2196/27175] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 04/11/2021] [Accepted: 04/15/2021] [Indexed: 01/10/2023] Open
Abstract
Background Technical capabilities for performing liver transplantation have developed rapidly; however, the lack of available livers has prompted the utilization of edge donor grafts, including those donated after circulatory death, older donors, and hepatic steatosis, thereby rendering it difficult to define optimal clinical outcomes. Objective We aimed to investigate the efficacy of telemedicine for follow-up management after liver transplantation. Methods To determine the efficacy of telemedicine for follow-up after liver transplantation, we performed a clinical observation cohort study to evaluate the rate of recovery, readmission rate within 30 days after discharge, mortality, and morbidity. Patients (n=110) who underwent liver transplantation (with livers from organ donation after citizen's death) were randomly assigned to receive either telemedicine-based follow-up management for 2 weeks in addition to the usual care or usual care follow-up only. Patients in the telemedicine group were given a robot free-of-charge for 2 weeks of follow-up. Using the robot, patients interacted daily, for approximately 20 minutes, with transplant specialists who assessed respiratory rate, electrocardiogram, blood pressure, oxygen saturation, and blood glucose level; asked patients about immunosuppressant medication use, diet, sleep, gastrointestinal function, exercise, and T-tube drainage; and recommended rehabilitation exercises. Results No differences were detected between patients in the telemedicine group (n=52) and those in the usual care group (n=50) regarding age (P=.17), the model for end-stage liver disease score (MELD, P=.14), operation time (P=.51), blood loss (P=.07), and transfusion volume (P=.13). The length and expenses of the initial hospitalization (P=.03 and P=.049) were lower in the telemedicine group than they were in the usual care follow-up group. The number of patients with MELD score ≥30 before liver transplantation was greater in the usual care follow-up group than that in the telemedicine group. Furthermore, the readmission rate within 30 days after discharge was markedly lower in the telemedicine group than in the usual care follow-up group (P=.02). The postoperative survival rates at 12 months in the telemedicine group and the usual care follow-up group were 94.2% and 90.0% (P=.65), respectively. Warning signs of complications were detected early and treated in time in the telemedicine group. Furthermore, no significant difference was detected in the long-term visit cumulative survival rate between the two groups (P=.50). Conclusions Rapid recovery and markedly lower readmission rates within 30 days after discharge were evident for telemedicine follow-up management of patients post–liver transplantation, which might be due to high-efficiency in perioperative and follow-up management. Moreover, telemedicine follow-up management promotes the self-management and medication adherence, which improves patients’ health-related quality of life and facilitates achieving optimal clinical outcomes in post–liver transplantation.

Abstract
PURPOSE To report a case of delayed splenic rupture after percutaneous transsplenic portal vein stent deployment. CASE REPORT A 72-year-old male patient presented at a medical center with abdominal pain and reduced liver function according to laboratory tests. Due to a history of right hemihepatectomy and left portal vein occlusion, the percutaneous transhepatic approach was considered inappropriate. Instead, percutaneous transsplenic access was selected as a suitable procedure for portal vein catheterization. Eight days following the procedure, the patient developed abdominal pain, and a computed tomography scan showed a small splenic pseudoaneurysm that was underappreciated at the time. Patient suffered acute splenic rupture 32 days post-procedure. Subsequent embolization was performed, achieving complete hemostasis. CONCLUSION The transsplenic approach should be considered when the transhepatic or transjugular approach is unfeasible or difficult to implement. A careful plugging of the puncture tract is necessary to prevent or minimize hemorrhage from the splenic access tract. In addition, careful serial follow-up computed tomography should be used to evaluate the splenic puncture tract.

Abstract
We present a case of a patient who underwent portal vein (PV) stenting for PV stenosis after a living-donor liver transplantation. A pretreatment 3D cine phase-contrast (4D-flow) MRI showed decreased, though hepatopetal, blood flow in the PV. After stenting, 4D-flow MRI confirmed an improvement in PV flow, with a more homogeneous flow distribution to each hepatic segment. 4D-flow MRI are valuable for understanding the hemodynamics of this area, planning for treatments, and evaluating the outcome of the interventions.

Abstract
BACKGROUND Portal vein stenosis develops in 3.4-14% of split liver transplantation1-3 and its early detection and treatment are essential to achieve long-term graft survival,2-5 although the diagnostic capability of conventional modalities such as Doppler ultrasound and computed tomography is limited.1,4,5 METHODS: This study used computational fluid dynamics to analyze portal vein hemodynamics in the management of post-transplant portal vein stenosis. To perform computational fluid dynamics analyses, three-dimensional portal vein model was created using computed tomographic DICOM data. The inlet flow condition was set according the flow velocity measured on Doppler ultrasonography. Finally, portal vein flow was simulated on a fluid analysis software (Software Cradle, Japan). RESULTS An 18-month-old girl underwent liver transplantation using a left lateral graft for biliary atresia. At the post-transplant 1-week evaluation, the computational fluid dynamics streamline analysis visualized vortices and an accelerated flow with a velocity ratio < 2 around the anastomotic site. The wall shear stress analysis revealed a high wall shear stress area within the post-anastomotic portal vein. At the post-transplant 6-month evaluation, the streamline analysis illustrated the increased vortices and worsening flow acceleration to reach the proposed diagnostic criteria (velocity ratio > 3:1).3,5 The pressure analysis revealed a positive pressure gradient of 3.8 mmHg across the stenotic site. Based on the findings, the patient underwent percutaneous transhepatic portal venoplasty with balloon dilation. The post-treatment analyses confirmed the improvement of a jet flow, vortices, a high wall shear stress, and a pressure gradient. DISCUSSION The computational fluid dynamics analyses are useful for prediction, early detection, and follow-up of post-transplant portal vein stenosis and would be a promising technology in post-transplant management.

Abstract
End-stage liver disease is characterized by multiple and complex alterations of hemostasis that are associated with an increased risk of both bleeding and thrombosis. Liver transplantation further challenges the feeble hemostatic balance of patients with decompensated cirrhosis, and the management of antithrombotic treatment during and after transplant surgery, which is particularly difficult. Bleeding was traditionally considered the major concern during and early after surgery, but it is increasingly recognized that transplant recipients may also develop thrombotic complications. Pathophysiology of hemostatic complications during and after transplantation is multifactorial and includes pre-, intra-, and postoperative risk factors. Risk stratification is important, as it helps the identification of high-risk recipients in whom antithrombotic prophylaxis should be considered. In recipients who develop thrombosis during or after surgery, prompt treatment is indicated to prevent graft failure, retransplantation, and death.

Abstract
Within the broad spectrum of pediatric hepatobiliary disorders, hepatic vascular malformations, portal hypertension, and hepatic transplant interventions pose numerous challenges. The role of interventional radiology within each of these conditions is discussed herein, beginning with endovascular management of high flow hepatic vascular malformations. Next, while becoming less common in adult populations, surgical portoportal and portosystemic shunts remain prevalent in many pediatric centers. Shunt anatomy is reviewed along with endovascular management techniques for shunt dysfunction. Next, the growing experience with pediatric transjugular intrahepatic portosystemic shunt placement is reviewed along with tips for success in pediatric patients. Finally, pediatric hepatic transplant interventions are discussed with technical notes pertinent to split liver anatomy.

Abstract
PURPOSE Advances in interventional radiology (IVR) treatment have notably improved the prognosis of hepatic vein (HV) and portal vein (PV) complications following pediatric living donor liver transplantation (LDLT); however, graft failure may develop in refractory cases. Although endovascular stent placement is considered for recurrent stenosis, its indications are controversial. METHODS We enrolled 282 patients who underwent pediatric LDLT in our department from May 2001 to September 2016. RESULTS 22 (7.8%) HV complications occurred after LDLT. Recurrence was observed in 45.5% of the patients after the initial treatment, and 2 patients (9.1%) underwent endovascular stent placement. The stents were inserted at 8 months and 3.8 years following LDLT, respectively. After stent placement, both patients developed thrombotic obstruction and are currently being considered for re-transplantation. 40 (14.2%) PV complications occurred after LDLT. Recurrence occurred in 27.5% of the patients after the initial treatment, and 4 patients (10.0%) underwent endovascular stent treatment. The stents of all the patients remained patent, with an average patency duration of 41 months. CONCLUSION Endovascular stent placement is an effective treatment for intractable PV complications following pediatric LDLT. However, endovascular stent placement for HV complications should be carefully performed because of the risk of intrastent thrombotic occlusion and the possibility of immunological venous injury.

Abstract
Extensive portosplenomesenteric thrombosis is regarded as a relative contraindication to liver transplantation because of the complexity of the surgical procedure. This report describes a case of living-donor liver transplantation (LDLT) for a patient with extensive portosplenomesenteric thrombosis, in whom portal flow was successfully restored by intraoperative transplenic portal vein and superior mesenteric vein stenting after surgical thrombectomy. The patient's liver function remained normal with a patent portal vein stent 6 months after LDLT, and Doppler ultrasonography demonstrated a normal wave form for portal flow. To the best of our knowledge, this is the world's first case of endovascular management of the portal vein via percutaneous transsplenic access during LDLT, demonstrating that transsplenic access can be an alternative approach without liver graft injury when the superior mesenteric vein branch and inferior mesenteric vein cannot be used as access routes.

Abstract
PURPOSE Extrahepatic portal vein obstruction (EHPVO) is the most frequent cause of portal hypertension in children. Some patients are not amenable to meso-Rex bypass and alternative surgeries do not restore physiologic flow. We aim to demonstrate the feasibility and safety of minilaparotomy for recanalization of chronic EHPVO. METHODS This 2013-2015 single-center, retrospective review included pediatric patients with chronic EHPVO who underwent minilaparotomy, mesenteric vein access, and attempted recanalization of the occluded portal vein. Outcomes included portal patency, resolution of variceal bleeding, size and number of varices, spleen size, and platelet count. RESULTS There were 6 EHPVO patients. The median age was 9.9 years and median duration of EHPVO was 7 years (3-16 years). EHPVO etiologies were liver transplantation (50%), idiopathic (33%), and umbilical vein catheterization (17%). Four patients (67%) had successful portal vein recanalization and stenting. At last follow-up [median 3.1 years (2.2-4.3 years)] all successfully recanalized patients had patent portal vein stents and resolution of varices and variceal bleeding. The median reduction in spleen size was 26%, with improvement in platelet counts (50-310/μL). The 2 patients with an idiopathic etiology may have never had a main extrahepatic portal vein based on imaging, and both were unable to be recanalized. CONCLUSIONS Recanalization and stenting of a prolonged occlusion of the portal vein via a minilaparotomy approach is feasible, safe, and may provide an alternative to shunt surgery or endoscopic therapy in selected patients.

Abstract
Portal vein thrombosis (PVT) is a severe complication after liver transplantation that can result in increased morbidity and mortality. Few data are available regarding risk factors, classification, and treatment of PVT after living donor liver transplantation (LDLT). Between January 2004 and November 2014, 421 adult-to-adult LDLTs were performed at our institution, and they were included in the analysis. Perioperative characteristics and outcomes from patients with no-PVT (n = 393) were compared with those with de novo PVT (total portal vein thrombosis [t-PVT]; n = 28). Ten patients had early portal vein thrombosis (e-PVT) occurring within 1 month, and 18 patients had late portal vein thrombosis (l-PVT) appearing later than 1 month after LDLT. Analysis of perioperative variables determined that splenectomy was associated with t-PVT (hazard ratio [HR], 3.55; P = 0.01), e-PVT (HR, 4.96; P = 0.04), and l-PVT (HR, 3.84; P = 0.03). In contrast, donor age was only found as a risk factor for l-PVT (HR, 1.05; P = 0.01). Salvage rate for treatment in e-PVT and l-PVT was 100% and 50%, respectively, without having an early event of rethrombosis. Mortality within 30 days did not show a significant difference between groups (no-PVT, 2% versus e-PVT, 10%; P = 0.15). No significant differences were found regarding 1-year (89% versus 92%), 5-year (79% versus 82%), and 10-year (69% versus 79%) graft survival between the t-PVT and no-PVT groups, respectively (P = 0.24). The 1-year (89% versus 96%), 5-year (82% versus 86%), and 10-year (79% versus 83%) patient survival was similar for the patients in the no-PVT and t-PVT groups, respectively (P = 0.70). No cases of graft loss occurred as a direct consequence of PVT. In conclusion, the early diagnosis and management of PVT after LDLT can lead to acceptable early and longterm results without affecting patient and graft survival.

Abstract
Portal vein thrombosis (PVT) may occur at any time following liver transplantation. We describe our experience with portal vein recanalization in cases of thrombosis after liver transplantation. Twenty-eight children (5%) out of 566 liver transplant recipients underwent portal vein recanalization using a transmesenteric approach. All children received left hepatic segments, developed PVT, and had symptoms or signs of portal hypertension. Portal vein recanalization was performed via the transmesenteric route in all cases. Twenty-two (78.6%) patients underwent successful recanalization and stent placement. They received oral anticoagulants after the procedure, and clinical symptoms subsided. Symptoms recurred due to portal vein restenosis/thrombosis in seven patients. On an intention-to-treat basis, the success rate of the proposed treatment was 60.7%. Only 17 out of 28 children with posttransplant chronic PVT retained stent patency (primary + assisted) at the end of the study period. In cases of portal vein obstruction, the transmesenteric approach via minilaparotomy is technically feasible with good clinical and hemodynamic results. It is an alternative procedure to reestablish the portal flow to the liver graft that can be performed in selected cases and a therapeutic addition to other treatment strategies currently used to treat chronic PVT.

Abstract
BACKGROUND Endovascular intervention with stent placement to treat portal vein (PV) and hepatic vein (HV) stenosis after pediatric liver transplantation (LT) is still controversial in small children owing to the potential risk of functional stenosis after growth. The aim of this study is to evaluate the safety and efficacy of stent placement in this population. METHODS Between 2004 and 2016, 6 children (all <3 years) received HV (n = 2) and PV (n = 4) stents placement among 46 pediatric LT patients at our institution. The clinical outcome and patency rate were followed. Morphologic changes of stents were assessed from plain films by a new index: the stent diameter ratio (SDR). RESULTS The median age of the patients at LT was 8.9 months. The patency rate was 100% without functional stenosis during a median follow-up period of 65.5 months. The "stent growth" phenomenon was demonstrated by SDR with significant resolution of hourglass deformity 2 years after stent placement (p for trend <.001). CONCLUSION Vascular stent placement is a safe and effective method for the management of PV and HV stenosis following pediatric LT because these stents will enlarge as children grow. TYPE OF STUDY Case Series with no Comparison Group LEVEL OF EVIDENCE: Level IV.

Abstract
Introduction Percutaneous transluminal angioplasty (PTA), with or without stent placement, has become the treatment of choice for portal vein complications (PVC) following liver transplantation. We aimed to assess long-term outcomes of intervention in paediatric transplant recipients, in a single institution. Materials and Methods 227 children received 255 transplants between November 2000 and September 2016. 30 patients developed PVC of whom 21 had percutaneous intervention. Retrospective clinical and procedural outcome data on these 21 patients were collected. Results 21 patients, with median age 1.7 years (range 0.4–16.2), underwent 42 procedures with PTA with or without stenting. 36 procedures were for PV stenosis and 6 for PV thrombosis. Treatment was with primary PTA, with stenting reserved for suboptimal PTA result or restenosis within 3 months. 28 procedures were performed with PTA and 13 with stenting. Technical success (>50% reduction in mean pressure gradient, absolute pressure gradient ≤4 mmHg or venographic stenosis <30%) was achieved in 41 procedures. Failure to recanalise a thrombosed PV occurred in 1 procedure. There were no major procedural complications. Patients were followed-up with serial Doppler ultrasound surveillance. Kaplan–Meier estimated median primary patency was 9.9 months, with primary-assisted patency of 95% after median follow-up of 45.5 months (range 11.1–171.6). Conclusion With regular surveillance, excellent patency rates can be achieved following percutaneous intervention for PVC post-paediatric liver transplantation.

Abstract
The purpose of this article is to evaluate and compare the safety and efficacy of endovascular management of the portal vein (PV) via percutaneous transsplenic access versus percutaneous transhepatic access in liver transplantation (LT) recipients. A total of 18 patients who underwent endovascular management of PV via percutaneous transhepatic (n = 8) and transsplenic (n = 10) access were enrolled. Transsplenic access was chosen if the spleen was located in a normal position, the splenic vein (SpV) was preserved, and the target lesion did not involve confluence of the superior mesenteric and SpVs. Accessibility of the percutaneous transsplenic puncture was confirmed via ultrasound (US) in the angiography suite. All procedures were performed under local anesthesia. Percutaneous transhepatic or transsplenic access was performed using a 21-gauge Chiba needle under US and fluoroscopic guidance, followed by balloon angioplasty, stent placement, or variceal embolization. The access tract was embolized using coils and a mixture (1:2) of glue and ethiodized oil. Transhepatic or transsplenic access was successfully achieved in all patients. A total of 12 patients underwent stent placement; 3 had balloon angioplasty only; 2 had variceal embolization only; and 1 had variceal embolization followed by successful stent placement. Regarding major complications, 1 patient experienced a SpV tear with extravasation during transsplenic balloon angioplasty, which was successfully managed using temporary balloon inflation, followed by transfusion. Clinical success was achieved in 9 of 11 (82%) patients who exhibited clinical manifestations. The remaining 7 patients who underwent prophylactic endovascular management were healthy. In conclusion, endovascular management of PV via percutaneous transsplenic access is a relatively safe and effective alternative that does not damage the liver grafts of LT recipients.

Abstract
Background Portal vein stenosis develops due to different causes including postoperative inflammation and oncological processes. However, limited effective therapy is available for portal vein stenosis. The objectives of this study were to evaluate the efficacy of a portal vein stent for portal vein stenosis after hepatobiliary pancreatic surgery and to determine the factors associated with stent patency. Methods From December 2003 to December 2015, portal vein stents were implanted in 29 patients who had portal vein stenosis after hepatobiliary pancreatic surgery. We conducted a retrospective analysis to evaluate the efficacy and safety of portal vein stent placement. Twelve clinical variables were analyzed for their role in stent patency. Results The symptoms before portal vein stent placements included nine patients with hepatic encephalopathy, six patients with gastrointestinal bleeding, four patients with ascites, and four patients with hyperbilirubinemia. Portal vein thrombosis due to postoperative portal stenosis was found in four patients. Portal vein stent were successfully implanted without any major complications. Of the 21 patients with symptoms, 17 showed improvement, and stent patency was maintained in 22 (76%) patients. The presence of a collateral vein is the only variable related to the development of an occlusion after portal stenting. Conclusion Portal vein stent were implanted safely and had good long-term patency. This procedure is useful to relieve portal hypertension-related symptoms and to improve the quality of life. Our data strongly suggest that embolization to block blood flow in a collateral vein during portal vein stent placement will improve the patency of the stent.

Abstract
BACKGROUND Although perioperative portal vein (PV) stent implantation is an effective treatment for steno-occlusive disease in adult living donor liver transplantation (LDLT) recipients, we experienced high incidence of biliary anastomotic strictures (BAS) after PV stenting. In this study, we sought to clarify the relation between BAS and PV stenting and to suggest the possible mechanism of BAS and measures to reduce its incidence. METHODS We retrospectively analyzed 44 LDLT recipients who underwent PV stent implantation across the line of PV anastomosis regardless of the location of steno-occlusion (stent group) and their matched controls (non-stented LDLT recipients, n=131). RESULTS The incidence of BAS was higher in patients in the stent group than that in the control group (43.2% vs 17.6%, P=0.001). Cumulative 6-month and 1-, 2- and 5-year BAS rates were 31.8%, 34.1%, 41.4% and 43.2%, respectively, in the stent group and 13.0%, 13.8%, 16.1% and 17.8%, respectively, in the control group (P=0.001). Multivariate analysis revealed that PV stenting was an independent risk factor for BAS. CONCLUSIONS Although PV stent implantation is a reliable treatment modality for steno-occlusive PV in adult LDLT recipients, innovative methods to prevent the PV stent from crossing the line of PV anastomosis may be necessary to reduce the incidence of postoperative BAS.

Abstract
Living-donor liver transplantation has provided a solution to the severe lack of cadaver grafts for the replacement of liver afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. Vascular complications remain the most serious complications and a common cause for graft failure after hepatic transplantation. Doppler ultrasound remains the primary radiological imaging modality for the diagnosis of such complications. This article presents a brief review of intra- and post-operative living donor liver transplantation anatomy and a synopsis of the role of ultrasonography and color Doppler in evaluating the graft vascular haemodynamics both during surgery and post-operatively in accurately defining the early vascular complications. Intra-operative ultrasonography of the liver graft provides the surgeon with useful real-time diagnostic and staging information that may result in an alteration in the planned surgical approach and corrections of surgical complications during the procedure of vascular anastomoses. The relevant intra-operative anatomy and the spectrum of normal and abnormal findings are described. Ultrasonography and color Doppler also provides the clinicians and surgeons early post-operative potential developmental complications that may occur during hospital stay. Early detection and thus early problem solving can make the difference between graft survival and failure.

Sonographic Evaluation of Post-transplantation Portal Vein Stenosis in Pediatric Living-donor Liver Transplant Recipients With Left-liver Grafts. Transplant Proc 2016; 48:1162-5.

Abstract
INTRODUCTION Portal vein (PV) stenosis is not uncommon in post-transplantation pediatric living-donor liver transplant (PLDLT) recipients. The purpose of this study was to identify specific ultrasound criteria that may be used to detect PV stenosis in PLDLT with left-liver grafts. PATIENTS AND METHODS From January 2010 to October 2014, 87 pediatric recipients underwent PLDLT with left lobes or left lateral segments at our hospital. All patients underwent routine liver Doppler ultrasound (DUS) as follow-up protocol. The morphologic narrowing and mean time averaged velocity (TAV) at the PV anastomotic site, change in anastomotic/pre-anastomotic TAV (ΔTAV), and the umbilical portal width were evaluated and analyzed. Ultrasound findings were correlated with computed tomography angiography where PV stenosis was suspected. RESULTS In the liver graft follow-up study, 80.4% (70 of 87 patients) of PV anastomosis was well visualized and measured by Doppler ultrasound. The optimal threshold values for TAV and ΔTAV were 49.6 cm/s and 30 cm/s, respectively, for significant PV anastomosis stenosis. In the other 19.5% (17/87), the PV anastomosis could not be identified properly. The PV anastomosis was not always visible with ultrasound; however, the optimal dilated umbilical portion of the PV indicating possible PV anastomosis narrowing threshold was umbilical portal width >1.5 cm. CONCLUSIONS Increased anastomotic TAV and ΔTAV are useful features for diagnosing PV stenosis. The identification of a dilated umbilical portion of the left PV helps in detection of PV stenosis in PLDLT recipients especially when the anastomotic narrowed region cannot be visualized.

Abstract
We describe a man who presented with a traumatic portal vein pseudoaneurysm, which was subsequently managed with a percutaneous transhepatic stent graft. This case demonstrates a rarely seen condition in the traumatic population and a novel management strategy, which should be considered in the management of this challenging injury.

Abstract
Although vascular complications (VCs) following orthotopic liver transplantation (OLT) seldom occur, they are the most feared complications with a high incidence of both graft loss and mortality, as they compromise the blood flow of the transplant (either inflow or outflow). Diagnosis and therapeutic management of VCs constitute a major challenge in terms of increasing the success rate of liver transplantation. While surgical treatment used to be considered the first choice for management, advances in endovascular intervention have increased to make this a viable therapeutic option. Considering VC as a rare but a major and dreadful issue in OLT history, and in view of the continuing and rapid progress in recent years, an update on these uncommon conditions seemed necessary. In this sense, this review comprehensively discusses the important features (epidemiological, clinical, paraclinical, prognostic and therapeutic) of VCs following OLT.
