RESUMEN

Patients receiving liver transplantation in a setting of complete portal vein (PV) and superior mesenteric vein (SMV) thrombosis (Yerdel grade 4) experience lower outcomes after surgery; prognosis is independently influenced by the portal flow reconstruction technique, showing better outcomes in physiological surgical strategies. We describe a case of living donor liver transplantation in which the patient could not receive common physiological reconstructions pre-operatively due to multiple small collaterals and extensive thrombosis down to 1st branches of SMV. We performed thrombo-endo-venectomy of the portal vein and SMV first, but acute thrombosis developed recurrently even with interposition venous homograft between peri-choledochal collateral vein and proximal recipient portal vein. Immediate after surgery, intervention radiologist performed stenting insertion into 3 stenotic points. Through multidisciplinary approach, complete physiologic recanalization was obtained with normal liver function.

RESUMEN

La trombosis de la vena porta (TVP) en pacientes con o sin cirrosis hepática (CH) se define como una obstrucción de la vena porta debido a la formación de un trombo que puede extenderse a las venas mesentéricas superiores y esplénica. Esta es una complicación común de la enfermedad hepática avanzada. Se creía que la TVP se producía predominantemente debido al potencial protrombótico del paciente con CH, ya que se observaba una mayor incidencia de TVP en CH con una puntuación MELD y Child-Pugh más altas, con una prevalencia informada del 10 % al 25%.


Portal vein thrombosis (PVT) in patients with or without hepatic cirrhosis (CH) is defined as an obstruction of the portal vein due to the formation of a thrombus that may extend to the superior mesenteric and splenic veins. This is a common complication of advanced liver disease. It was believed that PVT predominantly occurred due to the prothrombotic potential of the patient with CH, as a higher incidence of PVT was observed in CH with higher MELD and Child-Pugh scores, with a reported prevalence of 10% to 25%.

RESUMEN

The etiology of venous thromboembolism is multifactorial, with causes being classified as either provoked or unprovoked, making it difficult to attribute a single factor as the cause of the thromboembolic event in most cases. The relationship between inflammation and thrombotic phenomena is well established. Here, we describe the uncommon occurrence of thromboses in a previously healthy patient with acute toxoplasmosis. The patient initially presented with fatigue, abdominal pain, fever and dyspnea. The diagnosis was confirmed through toxoplasmosis serology in a set of admission laboratory tests, and further imaging studies revealed the presence of pulmonary embolism and portal vein thrombosis. The patient was treated with anticoagulants and sulfamethoxazole-trimethoprim, showing improvement in the following days. This case highlights the importance of considering infectious diseases, such as toxoplasmosis, in the differential diagnosis of thrombosis, even in previously healthy individuals. To our knowledge, this is the second reported case of this association in Brazil.

RESUMEN

OBJECTIVES: Portal hypertension resulting from non-cirrhotic extrahepatic portal vein obstruction (EHPVO) in children has been primarily managed with the Meso-Rex bypass, but only a few patients have a viable Rex recessus, required by surgery. This study reports a preliminary series of patients who underwent interventional radiology attempts at portal vein recanalization (PVR), with a focus on technical aspects and safety. METHODS: A retrospective review of consecutive patients with severe portal hypertension due to non-cirrhotic EHPVO at a single institution from 2022, who underwent percutaneous attempts at PVR, was performed. Technical and clinical data including fluoroscopy time, radiation exposure, technical and clinical success, complications and follow-up were recorded. RESULTS: Eleven patients (6 males and 5 females; median age 7 years, range 1-14) underwent 15 percutaneous transhepatic (n = 1), transplenic (n = 11), or simultaneous transhepatic/transplenic (n = 3) procedures. Rex recessus was patent in 4/11 (36%). Fluoroscopy resulted in a high median total dose area product (DAP) of 123 Gycm2 (range 17-788 Gycm2) per procedure. PVR was achieved in 5/11 patients (45%), 3/5 with obliterated Rex recessus. Two adverse events of grade 2 and grade 3 occurred without sequelae. After angioplasty, 4/5 patients required stenting to obtain sustained patency, as demonstrated by colour-Doppler ultrasound in all PVR after a median follow-up of 6 months (range 6-14). CONCLUSION: Our preliminary experience suggests that 45% of children with non-cirrhotic EHPVO can restore portal flow even with obliterated Rex recessus. In non-cirrhotic EHPVO, PVR may be an option, if a Meso-Rex bypass is not feasible, although the radiation exposure deserves attention. CLINICAL RELEVANCE STATEMENT: Innovative percutaneous procedures may have the potential to be an alternative option to the traditional surgical approach in the management of non-cirrhotic EHPVO and its complications in children not eligible for Meso-Rex bypass surgery. KEY POINTS: Non-cirrhotic portal hypertension in children has been traditionally managed by surgery with Meso-Rex bypass creation. Percutaneous PVR may restore the patency of the native portal system even when the Rex recessus is obliterated and surgery has been excluded. Interventional radiological techniques may offer a minimally invasive solution in complex cases of EHPVO in children when Meso-Rex bypass is not feasible.

RESUMEN

Portal vein thrombosis (PVT) poses significant therapeutic challenges due to its complex pathophysiology and diverse clinical presentations. Recent advancements have spurred the development of new therapeutic approaches to enhance treatment efficacy and safety. This review synthesized emerging therapies for PVT based on a comprehensive literature search across major databases such as PubMed, EMBASE, and Web of Science, among others, focusing on studies published in the last decade. Anticoagulation therapy, particularly with novel oral anticoagulants (NOACs), emerged as beneficial in personalized treatment regimens. Innovative surgical techniques and improved risk stratification methods were identified as crucial in the perioperative management of PVT. Additionally, advances in cell therapy and medical treatments for hepatocellular carcinoma in the context of PVT were explored. Promising outcomes were observed with modalities such as Yttrium 90 and liver transplantation combined with thrombectomy, particularly in complex PVT cases associated with hepatocellular carcinoma, albeit on a limited scale. The reviewed literature indicates a shift towards individualized treatment approaches for PVT, integrating novel anticoagulants, refined risk assessment tools, and tailored interventional strategies. While these emerging therapies show potential for enhanced efficacy and safety, further research is essential to validate findings across broader patient populations and establish standardized treatment protocols.

RESUMEN

Portal cavernoma is a major cause of extrahepatic portal hypertension (EHPH) in children. It is a serious condition, due to the frequency and severity of digestive hemorrhages secondary to the rupture of esophageal varices (EV). Neonatal umbilical catheterization is a significant risk factor for the development of portal vein thrombosis (PVT) and portal hypertension. We report a case of a five-year-old male who presented with upper gastrointestinal (GI) bleeding on ruptured esophageal varices resulting from a portal cavernoma, complicating neonatal umbilical vein catheterization. This case illustrates the risk of severe vascular complications, particularly portal hypertension that can result from neonatal umbilical vein catheterization.

RESUMEN

Background: Multiple studies have linked COVID-19 to a higher incidence of thromboembolic disorders. However, the association of COVID-19 with other potentially life-threatening complications, such as splanchnic vein thrombosis, is less well understood. This study aims to assess the prevalence, patient characteristics, clinical presentation, and outcomes of patients with portal vein thrombosis (PVT) and COVID-19. Methods: This was a retrospective observational study. From all positive patients for a reverse-transcription polymerase chain reaction (RT-PCR) swab test from March 2020 to June 2020, we included those who were older than 18 years, had received abdominal contrast-enhanced computed tomography (CT) in the 6 months following the positive RT-PCR swab, and had no previously known splanchnic vein thrombosis. Results: A total of 60 patients with abdominal CT were selected from all those positive for SARS-CoV-2 (n = 2987). The prevalence of PVT was 3/60 (5%). The mean age was 66.1 ± 16.5 years and 51.7% were male. In two of the three patients, there was no underlying pathology as a risk factor for PVT and one of them presented cirrhosis. The number of days from the start of COVID-19 symptoms until the PVT diagnosis were 21, 12, and 10 days. Anticoagulation treatment achieved recanalization in 100% of cases. During a mean follow-up of 803 days, none of the patients experienced long-term complications. Conclusions: Portal vein thrombosis is uncommon, and its incidence may be higher in COVID-19 patients. A greater understanding of the features of this disease in the context of COVID-19 could aid towards its diagnosis and allow for early detection and management.

RESUMEN

INTRODUCTION AND IMPORTANCE: As the obesity rate continues to rise, portal vein thrombosis (PVT) has emerged as a more frequent complication following bariatric surgery, with an incidence reported at approximately 0.4 % according to recent meta-analyses. PVT, characterized by the development of a thrombus within the portal vein, can be life-threatening due to its subtle and often nonspecific symptoms, complicating timely diagnosis and treatment. CASE PRESENTATION: In this case report, we present a 45-year-old female patient with a history of morbid obesity who underwent robotic-assisted laparoscopic sleeve gastrectomy and hiatal hernia repair. On postoperative day 16, she developed symptoms of severe abdominal pain and intolerance to oral intake, suggesting the presence of portal vein thrombosis. Laboratory findings showed significantly elevated D-dimer levels, and contrast-enhanced CT imaging confirmed an extensive thrombus within the portal vein. The patient was promptly admitted to the critical care unit, where she was managed conservatively with therapeutic anticoagulation, including subcutaneous heparin preoperatively and postoperatively, and discharged with a prescription for apixaban. CLINICAL DISCUSSION: Early diagnosis of PVT in the post-bariatric population is critical, as it allows for timely intervention with evidence-based therapeutic options such as anticoagulation, thereby improving both short- and long-term patient outcomes. This case not only underscores the importance of heightened vigilance for PVT in patients presenting with nonspecific abdominal symptoms after bariatric surgery but also highlights the potential risk factors unique to this patient, such as prolonged operative time and underlying comorbidities, which may have contributed to the thrombotic event. A multidisciplinary approach, involving both medical and surgical teams, is essential for optimal management of such complex cases. CONCLUSION: This case underscores the critical importance of early recognition and prompt management of portal vein thrombosis in post-bariatric surgery patients. By emphasizing the role of thorough perioperative DVT prophylaxis, including the use of heparin and sequential compression devices, this report not only aims to improve patient outcomes but also contributes to the growing body of knowledge on the prevention and treatment of PVT in the bariatric population. These insights may serve as a valuable framework for managing similar clinical scenarios in the future.

RESUMEN

Superior mesenteric venous (SMV) thrombosis is a rare complication of severe appendicitis. Early recognition is due to improved imaging modalities, which ultimately lead to more prompt intervention. Despite being an uncommon phenomenon, SMV thrombosis can have complications stemming from venous hypertension, such as gastric and esophageal varices, bowel ischemia, sepsis, and death. As this is a rare phenomenon, specific treatment guidelines and algorithms are lacking in the current literature. This case report describes a 23-year-old male patient whose recovery from a laparoscopic appendectomy was complicated with both an SMV and portal vein thrombosis.

RESUMEN

OBJECTIVE: The relationship between lymphocyte-associated inflammatory indices and portal vein thrombosis (PVT) following splenectomy combined with esophagogastric devascularization (SED) is currently unclear. This study aims to investigate the association between these inflammatory indices and PVT, and to develop a nomogram based on these indices to predict the risk of PVT after SED, providing an early warning tool for clinical practice. METHODS: We conducted a retrospective analysis of clinical data from 131 cirrhotic patients who underwent SED at Lanzhou University's Second Hospital between January 2014 and January 2024. Independent risk factors for PVT were identified through univariate and multivariate logistic regression analyses, and the best variables were selected using the Akaike Information Criterion (AIC) to construct the nomogram. The model's predictive performance was assessed through receiver operating characteristic (ROC), calibration, decision, and clinical impact curves, with bootstrap resampling used for internal validation. RESULTS: The final model incorporated five variables: splenic vein diameter (SVD), D-Dimer, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and red cell distribution width-to-lymphocyte ratio (RLR), achieving an area under the curve (AUC) of 0.807, demonstrating high predictive accuracy. Calibration and decision curves demonstrated good calibration and significant clinical benefits. The model exhibited good stability through internal validation. CONCLUSION: The nomogram model based on lymphocyte-associated inflammatory indices effectively predicts the risk of portal vein thrombosis after SED, demonstrating high accuracy and clinical utility. Further validation in larger, multicenter studies is needed.

RESUMEN

BACKGROUND AND AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) is an established procedure for the treatment of several complications of portal hypertension (PH), including non-neoplastic portal vein thrombosis (PVT). Selection criteria for TIPS in PVT are not yet well established. Despite anecdotal, cases of thromboembolic events from paradoxical embolism due to the presence of patent foramen ovale (PFO) after TIPS placement have been reported in the literature. Therefore, we aimed at describing our experience in patients with non-neoplastic splanchnic vein thrombosis (SVT) who underwent TIPS following PFO screening. METHODS: We conducted a single-centre retrospective study, including consecutive patients who underwent TIPS for the complications of cirrhotic and non-cirrhotic portal hypertension (NCPH) and having SVT. RESULTS: Of 100 TIPS placed in patients with SVT, 85 patients were screened for PFO by bubble-contrast transthoracic echocardiography (TTE) with PFO being detected in 22 (26%) cases. PFO was more frequently detected in patients with non-cirrhotic portal hypertension (NCPH) (23% in the PFO group vs. 6% in those without PFO, p = .04) and cavernomatosis (46% in the PFO group vs. 19% in those without PFO, p = .008). Percutaneous closure was effectively performed in 11 (50%) after multidisciplinary evaluation of anatomical and clinical features. No major complications were observed following closure. CONCLUSIONS: PFO screening and treatment may be considered feasible for patients with SVT who undergo TIPS placement.

RESUMEN

OBJECTIVES: This study aimed to evaluate the feasibility, safety, and efficacy of the transjugular mesenteric-caval shunt (TMCS) as a treatment for the cavernous transformation of the portal vein (CTPV) and recurrent variceal bleeding. METHODS: This retrospective case series was conducted with approval from the institutional review board. It involved seven patients diagnosed with CTPV and recurrent variceal bleeding who underwent the TMCS procedure. We analyzed the rate of procedural complications, incidents of rebleeding, stent stenosis, hepatic encephalopathy, and overall survival to assess treatment outcomes. RESULTS: The TMCS was successfully performed in all seven patients without any life-threatening complications. Postoperatively, one patient developed a lung infection and pleural effusion, which resolved with appropriate treatment. Additionally, two patients experienced an increase in total bilirubin levels, but there was no further deterioration in liver function. The median portal pressure gradient significantly decreased from a preoperative value of 27 mmHg (range 20-36 mmHg) to a postoperative value of 6 mmHg (range 4-11 mmHg). A notable improvement was observed in one cirrhotic patient, with liver function progressing from Child-Pugh class B (score 9) to class A (score 6). Over a median follow-up period of 14 months (range 7-18 months), none of the patients encountered rebleeding, stent stenosis, hepatic encephalopathy, or mortality. CONCLUSION: The TMCS appears to be a viable and effective alternative for managing CTPV with recurrent variceal bleeding. Its long-term outcome requires further evaluation. CLINICAL RELEVANCE STATEMENT: TMCS provides a promising treatment for patients with life-threatening CTPV complications when occluded portal vein cannot be recanalized and portal vein recanalization TIPS is not an option. KEY POINTS: Performing TIPS in patients with portal vein cavernoma is complex due to the requirement for recanalization of the occluded portal vein. Creating a mesenteric-caval shunt through a transjugular approach is a feasible technique. Establishing a TMCS provides a means to manage life-threatening complications arising from portal vein cavernoma.

RESUMEN

Background and Aims: Hypoalbuminemia, as defined by serum albumin (SA) levels ≤35 g/L, is associated to venous and arterial thrombosis in general population and in patients at risk of cardiovascular disease. It is unknown if SA ≤35 g/L is also associated to portal vein thrombosis (PVT) in cirrhosis. Methods: Cirrhotic patients enrolled in the Portal vein thrombosis Relevance On Liver cirrhosis: Italian Venous thrombotic Events Registry (PRO-LIVER) study (n = 753), were followed-up for 2 years to assess the risk of PVT, that was diagnosed by Doppler ultrasonography. Child-Pugh classes, Model for End-Stage Liver Disease score, presence of hepatocellular carcinoma and laboratory variables including SA, D-dimer, and high-sensitivity C-reactive protein (hs-CRP) were measured at baseline. Results: SA ≤35 g/L was detected in 52% of patients. A logistic multivariate regression analysis showed that higher Child-Pugh class, hepatocellular carcinoma and thrombocytopenia were significantly associated to SA ≤35 g/L. In a subgroup of patients where data regarding hs-CRP and D-dimer were available, SA ≤35 g/L was inversely associated with hs-CRP and D-dimer. During the follow-up, a total of 61 patients experienced PVT. A Kaplan Meier survival analysis showed SA ≤35 g/L was associated to increased risk of PVT compared to SA >35 g/L (P = .005). A multivariate Cox proportional hazards regression analysis showed that male sex, lower platelet count, and SA ≤35 g/L remained associated to PVT after adjusting for confounding factors. Conclusion: Cirrhotic patients with SA ≤35 g/L are at higher risk of experiencing PVT compared to those with SA >35 g/L and could be considered as potential candidates to anticoagulant prophylaxis for PVT prevention.

RESUMEN

Portal vein thrombosis (PVT) is a challenging and controversial complication of cirrhosis. Experimental models that reproduce cirrhotic PVT and effective pharmacological therapies are limited. We aimed to investigate the nature course and mechanisms of PVT in cirrhosis. A novel PVT model was developed via two-step total portal vein ligation in healthy and thioacetamide (TAA)-cirrhotic rats. Circulating and liver-infiltrating neutrophils were isolated from individuals with cirrhosis to examine neutrophil extracellular traps (NETs) and explore their unique characteristics and implications in PVT-associated fibrosis in cirrhosis. We further validated macrophage-myofibroblast transition (MMT) via multiplex immunofluorescence and single-cell sequencing. In the experimental model, cirrhosis promoted PVT development and portal vein intimal thickening. Interestingly, cirrhosis promoted spontaneous resolution of PVT due to instability of thrombus structure, along with pulmonary and intrahepatic clots. NETs-MMT mediate cirrhotic PVT and PVT-associated fibrosis, including fibrotic thrombus remodeling and increased hepatic collagen deposition. Mechanistically, caspase-4-dependent activation of neutrophils and GSDMD mediated the formation of NETs. The extracellular DNA of NETs promoted TGF-ß1/Smad3-driven MMT. Inhibiting GSDMD with disulfiram suppressed cirrhotic PVT and prevented associated fibrosis. The cirrhotic PVT model reflected the following three main characteristics of cirrhotic PVT: spontaneous resolution, immunothrombosis, and intimal fibrosis. Targeting NETs with GSDMD inhibitors may serve as a new therapeutic concept to treat cirrhotic PVT.

RESUMEN

Key Clinical Message: Accidental foreign body ingestion is the most common hidden cause of abdominal pain. A high index of suspicion should be implemented in patients with unresolved abdominal pain. Here we reported a 54-year-old patient with vague abdominal pain who had a successful laparoscopic removal of a toothpick. Abstract: Toothpicks and fish bones are considered one of the most common accidentally ingested foreign bodies. Fortunately, most patients are asymptomatic. About 80%-90% of ingested foreign bodies pass through the gut spontaneously within a week. We present a case of a 54-year-old female with chronic epigastric pain and fever found to have a foreign body (toothpick) that penetrated the stomach and migrated to the liver causing liver abscess with portal vein thrombosis. The patient was managed with laparoscopic removal of the foreign body with an uneventful postoperative course.

RESUMEN

Among the risk factors and underlying etiology of acute portal vein thrombosis, viral hepatitis is an extremely rare cause. We report a case of a young healthy 40-year-old male who was diagnosed with acute hepatitis A virus infection and presented with acute portal vein thrombosis. This article describes the possible pathophysiological mechanisms, clinical symptoms, and treatment of acute portal vein thrombosis in this patient. Based on this patient's history and treatment, we encourage testing for hepatitis A serological markers in the emergency department in a population with recent hepatitis A exposure risk factors and concurrent unexplained acute portal thrombosis.

RESUMEN

BACKGROUND: Portal vein arterialization (PVA) has been used in liver transplantation (LT) to maximize oxygen delivery when arterial circulation is compromised or has been used as an alternative reperfusion technique for complex portal vein thrombosis (PVT). The effect of PVA on portal perfusion and primary graft dysfunction (PGD) has not been assessed. AIM: To examine the outcomes of patients who required PVA in correlation with their LT procedure. METHODS: All patients receiving PVA and LT at the Fundacion Santa Fe de Bogota between 2011 and 2022 were analyzed. To account for the time-sensitive effects of graft perfusion, patients were classified into two groups: prereperfusion (pre-PVA), if the arterioportal anastomosis was performed before graft revascularization, and postreperfusion (post-PVA), if PVA was performed afterward. The pre-PVA rationale contemplated poor portal hemodynamics, severe vascular steal, or PVT. Post-PVA was considered if graft hypoperfusion became evident. Conservative interventions were attempted before PVA. RESULTS: A total of 25 cases were identified: 15 before and 10 after graft reperfusion. Pre-PVA patients were more affected by diabetes, decompensated cirrhosis, impaired portal vein (PV) hemodynamics, and PVT. PGD was less common after pre-PVA (20.0% vs 60.0%) (P = 0.041). Those who developed PGD had a smaller increase in PV velocity (25.00 cm/s vs 73.42 cm/s) (P = 0.036) and flow (1.31 L/min vs 3.34 L/min) (P = 0.136) after arterialization. Nine patients required PVA closure (median time: 62 d). Pre-PVA and non-PGD cases had better survival rates than their counterparts (56.09 months vs 22.77 months and 54.15 months vs 31.91 months, respectively). CONCLUSION: This is the largest report presenting PVA in LT. Results suggest that pre-PVA provides better graft perfusion than post-PVA. Graft hyperperfusion could play a protective role against PGD.

RESUMEN

Portal vein thrombosis (PVT) is a rare condition, particularly in non-cirrhotic patients. Anticoagulation remains the mainstay of the treatment. Extensive PVT can lead to variceal bleeding, ascites, bowel ischemia, and hypersplenism. The role of thrombolysis and thrombectomy in these patients remains unclear. However, there is evidence that local thrombolysis and thrombectomy should be considered in those who remain symptomatic on anticoagulation and are at risk of complications with acute PVT.

RESUMEN

To avoid recurrent variceal bleeding, transjugular intrahepatic portosystemic shunt (TIPS) in conjunction with variceal embolization is considered to be an effective strategy. However, due to changes in conditions and variations in the patient's state, individuals undergoing TIPS may face challenges and limitations during procedures. The transjugular technique and combined transsplenic portal venous recanalization (PVR) with TIPS were not effective in this case due to a blocked portal vein and a previous splenectomy. With an abdominal incision, we successfully punctured the mesenteric venous system and navigated the occluded segment of the portal vein through the mesenteric approach. TIPS was then performed under balloon guidance. This study aims to explore the management of risks and complications during surgical operations and propose multiple preoperative surgical techniques to improve the success rate of the procedure.

RESUMEN

Managing cirrhosis complications is an important measure for improving patients' clinical outcomes. Therefore, in order to provide a complete disease assessment and comprehensive treatment, improve quality of life, and improve the prognosis for patients with cirrhosis, it is necessary to pay attention to complications such as thrombocytopenia and portal vein thrombosis in addition to common or severe complications such as ascites, esophagogastric variceal bleeding, hepatic encephalopathy, and hepatorenal syndrome. The relevant concept that an effective albumin concentration is more helpful in predicting the cirrhosis outcome is gradually being accepted; however, the detection method still needs further standardization and commercialization.
