Int Med Case Rep J 2024; 17:381-386. [PMID: 38681996 PMCID: PMC11055520 DOI: 10.2147/imcrj.s453341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 04/13/2024] [Indexed: 05/01/2024] Open
Abstract
Purpose Idiopathic portal hypertension (IPH) also known as non-cirrhotic portal hypertension is an entity of hepatic conditions including disorders of blood vessels that leads to portal hypertension (PHT). Current management of PHT includes medical or endoscopic therapy. A proximal spleno-renal shunt (PSRS) operation has been shown to improve the outcomes of patients with IPH with upper gastrointestinal bleeding refractory to medical and endoscopic therapy in high income countries but the same has not been well described in our resource limited setting. Patients and methods This study consecutively included patients who were diagnosed with IPH on pre-operative imaging and underwent PSRS surgery. Data on four patients across the time period of 3 years was obtained with a male to female ratio of 1:1 and age range of 7 to 34 years. Results All patients in this study had features of upper gastrointestinal bleeding and, after an endoscopy they were all diagnosed with grade IV esophageal varices. Symptom duration prior to admission varied between 3 months to 8 years. All these patients had multiple episodes of rebleeding varices with recurrent admissions and were managed conservatively by multiple blood transfusions and propranolol tablets, pre-operatively. Only one patient had previous variceal band ligation done though he developed rebleeding. All four patients underwent both PSRS surgery and splenectomy and were intra-operatively verified to have a normal smooth liver and thus IPH was the cause of the esophageal varices. After an average follow-up period of 26.5 months, we found that all patients were alive with early symptomatic relief, no recurrent bleeding and no long-term complications. Conclusion Good outcomes were achieved in terms of symptom resolution, endoscopic variceal resolution at follow-up endoscopy, length of stay ranging from 8 to 15 days and all four patients were alive at the time of follow-up, that ranged from 14 to 46 months.

Abstract
Purpose Limited data exist regarding outcome and morbidity associated with portosystemic shunts in the pediatric transplant population. Our study assesses the outcomes of pediatric patients who underwent a portosystemic shunt procedure, both with and without liver transplantation (LT). Methods This study retrospectively reviewed the medical records of pediatric patients aged 0-19 years who underwent shunt placement between 2003 and 2017 at a tertiary care center. The analysis included cases of shunt placement with or without LT. Results A total of 13 pediatric patients were included in the study with median age of 8.8 years. Among the cases, 11 out of 13 (84.6%) underwent splenorenal shunt, 1 (7.7%) underwent a mesocaval shunt, and another 1 (7.7%) underwent a Modified Rex (mesoportal) shunt. Additionally, 5 out of 13 (38.5%) patients had LT, with 4 out of 5 (80.0%) receiving the transplant before shunt placement, and 1 out of 5 (20.0%) receiving it after shunt placement. Gastrointestinal bleeding resulting from portal hypertension was the indication in all cases. A total of 10 complications were reported in 5 patients; the most common complication was anemia in 3 (23.1%) patients. At the most recent follow-up visit, the shunts were functional without encephalopathy, and no deaths were reported. Conclusion Shunt placement plays a crucial role in the management of patients with portal hypertension. Our study demonstrates favorable long-term outcomes in pediatric patients who underwent shunt placement. Long term shunt outcomes were similar and unremarkable in patients with LT and without LT.

Abstract
Backgrounds/Aims Proximal splenorenal shunt (PSRS) is considered a one-time treatment for noncirrhotic portal hypertension (NCPH) to prevent recurrent upper gastrointestinal (UGI) hemorrhage and long-term complications. Long-term shunt patency is necessary to achieve these. The lie of the shunt is a contributing factor to early shunt thrombosis. We investigated the role of resection of the distal tail of pancreas (caudal pancreatectomy [CP]) in improving the lie of shunt and decreasing shunt thrombosis. Methods This was a retrospective cohort study of patients with NCPH who underwent PSRS between 2014-2020 in JIPMER, Puducherry, India. CP was performed in patients with a long tail of pancreas, with the tip of pancreatic tail extending up to splenic hilum on preoperative CT. Perioperative parameters and shunt patency rate of patients who underwent PSRS with CP (Group A) were compared with patients undergoing conventional PSRS (Group B). Statistical analysis was performed using the Mann-Whitney U test and χ2 test. Results Eighty four patients with NCPH underwent PSRS (extrahepatic portal vein obstruction = 39; noncirrhotic portal fibrosis = 45). Blood loss was lower (p = 0.002) and post-shunt fall in portal pressure higher (p = 0.002) in Group A. Shunt thrombosis rate was lower (p = 0.04) while rate of complete variceal regression (p = 0.03) and biochemical pancreatic leak (p = 0.01) were higher in Group A.There was no clinically relevant pancreatic fistula in either group. Conclusions CP is a safe and useful technique for reducing shunt thrombosis after PSRS in patients with NCPH by improving the lie of shunt.

Abstract
Portal hypertensive bleeding is a major complication of portal hypertension (PHT) with high morbidity and mortality. A lot of advances have been made in our understanding of screening, risk stratification, and management strategies for portal hypertensive bleeding including acute variceal bleeding leading to improved overall outcomes in patients with PHT. A number of guidelines on variceal bleeding have been published by various societies in the past few years. The Indian Society of Gastroenterology (ISG) Task Force on Upper Gastrointestinal Bleeding (UGIB) felt that it was necessary to bring out a standard practice guidance document for the use of Indian health care providers especially physicians, gastroenterologists, and hepatologists. For this purpose, an expert group meeting was convened by the ISG Task Force to deliberate on this matter and write a consensus guidance document for Indian practice. The delegates including gastroenterologists, hepatologists, radiologists, and surgeons from different parts of the country participated in the consensus development meeting at Coorg in 2018. A core group was constituted which reviewed all published literature on portal hypertensive UGIB with special reference to the Indian scenario and prepared unambiguous statements on different aspects for voting and consensus in the whole group. This consensus was produced through a modified Delphi process and reflects our current understanding and recommendations for the diagnosis and management of portal hypertensive UGIB in Indians. Intended for use by the health care providers especially gastroenterologists and hepatologists, these consensus statements provide an evidence-based approach to risk stratification, diagnosis, and management of patients with portal hypertensive bleeding.

Abstract
BACKGROUND Surgical portosystemic shunts are rare. We reviewed indications, operative details, and outcomes of patients undergoing surgical portosystemic shunt procedures. METHODS We retrospectively reviewed clinical data of consecutive patients between 1997 and 2018 from a single institution. Clinical characteristics and outcomes were compared between two groups: patients with portomesenteric venous thrombosis (PMVT) vs those with cirrhosis. Endpoints included 30-day mortality, shunt-related complications, patency, and survival. RESULTS There were 99 patients, 45 male and 54 female, with a mean age of 46 ± 18 years, enrolled in the study. There were 63 patients (63%) with PMVT and 36 patients (36%) with cirrhosis. Both groups had similar demographics, cardiovascular risk factors, and aneurysm extent, except for more diabetes among those with cirrhosis (p < 0.05). There were no significant differences in procedural metrics and intra-procedure complications between groups, except that patients with PMVT underwent more non-selective shunts than those with cirrhosis (63% vs. 30%, p < 0.001). There were two 30-day deaths (2%), with no difference in mortality and MAEs between groups. On univariate analysis, cholangiopathy and PMVT were associated with graft thrombosis (HR = 9.22, 95% CI 1.22-70.27) while race, smoking, cardiac comorbidity, type of operative shunt, configuration of the shunt, and use of conduit were not (p > 0.05). Patients with PMVT had significantly lower 1-, 5-, and 10-year primary (77%, 71%, and 71% vs. 97%, p = 0.009) and secondary patency (88%, 76%, and 72% vs. 96%, p = 0.027) compared with those with cirrhosis. The 1-, 5-, and 10-year survival rates were 94%, 84%, and 61% for patients with PMVT compared with 88%, 58%, and 26% for those with cirrhosis (non-adjusted HR 0.40, 95% CI 0.19-0.84, p = 0.01, age-adjusted HR 0.51, 95% CI 0.24-1.09, p = 0.08). The survival of patients with PMVT without liver disease trended higher than those with liver disease; however, when adjusted for age, the survival gap narrowed, and the difference was not statistically significant (p = 0.19), survival being lowest for those with PMVT and liver disease. CONCLUSIONS Surgical portosystemic shunts are safe and effective for symptom relief in selected patients with portal hypertension. The odds of graft thrombosis is 9 times higher in patients with PMVT. Overall survival is similar in patients with PMVT or cirrhosis.

Abstract
Backgrounds/Aims Proximal splenorenal shunt (PSRS) is usually done in symptomatic non-cirrhotic portal fibrosis (NCPF). The outcomes of splenectomy with endotherapy in non-bleeder NCPF patients has not been well studied. We here by aimed to study the post-surgical outcomes on short and long-term basis between PSRS and splenectomy among non-bleeder NCPF patients. Methods The consecutive non-bleeder NCPF patients whom underwent either splenectomy or PSRS from 2008 to 2016 were enrolled. The patients were followed up post-surgery clinically and biochemical investigations, Doppler ultrasound and upper gastrointestinal endoscopy were done as required. The peri-operative parameters compared were operative time, blood loss, hospital stay and morbidity. The long-term outcome measures compared were incidence of portal hypertension (PHTN) related bleed, change in grade of varices, shunt patency, shunt complications and thrombosis of spleno-portal axis. Results Among 40 patients with non-bleeder status, 24 underwent splenectomy and 16 underwent PSRS. The baseline characteristics including indication of surgery, biochemical investigations and grade of varices were comparable between PSRS and splenectomy. The peri-operative morbidity was not significantly different between two groups. The median follow up duration was 42 months (12-72 months), the decrement in grade of varices was significantly higher in PSRS group (p=0.03), symptomatic PHTN related UGIB was non-significant between PSRS and splenectomy (p=0.5). In PSRS group, 3 (18.3%) patients had shunt thrombosis (n=1) & encephalopathy (n=2) while in splenectomy group two patients developed thrombosis of splenoportal axis. Conclusions Splenectomy with endotherapy is alternative to PSRS in non-bleeder NCPF patients with indications for surgery.

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
Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are prototype noncirrhotic causes of portal hypertension (PHT), characterized by normal hepatic venous pressure gradient, variceal bleeds, and moderate to massive splenomegaly with preserved liver synthetic functions. Infections, toxins, and immunologic, prothrombotic and genetic disorders are possible causes in IPH, whereas prothrombotic and local factors around the portal vein lead to EHPVO. Growth failure, portal biliopathy, and minimal hepatic encephalopathy are long-term concerns in EHPVO. Surgical shunts and transjugular intrahepatic portosystemic shunt resolve the complications secondary to PHT. Meso-Rex shunt is now the standard-of-care surgery in children with EHPVO.

[PMID: 31273428 DOI: 10.1007/s00247-019-04458-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Revised: 04/30/2019] [Accepted: 06/18/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Published data describing the endovascular treatment of dysfunctional mesoportal and portosystemic shunts in the pediatric population are limited. OBJECTIVE We sought to describe the treatment and follow-up of such shunts managed by interventional radiology at a single pediatric hospital. We hypothesized that stenotic and occluded pediatric portosystemic and mesoportal shunts can be maintained patent by interventional radiology in the moderate term. MATERIALS AND METHODS We conducted a single-center retrospective study at a tertiary pediatric hospital. We included children with surgical mesoportal (meso-Rex) or portosystemic (mesocaval, splenorenal or splenocaval) shunts treated with attempted angioplasty or stenting from 2010 to 2018. Technical success was defined as catheterization and intervention upon the shunt with venographic evidence of flow improvement. The primary outcome variables were shunt patency at 1 month, 6 months, 12 months and 24 months post-procedure and freedom from reintervention. RESULTS Twenty pediatric patients (11 boys, 9 girls; mean age 8.25 years, range 1.3-17 years) met inclusion criteria. Fifty-two interventions (primary and reintervention) on 13 splenorenal, 3 meso-Rex, 2 mesocaval and 2 splenocaval shunts were performed because of evidence of shunt failure, including gastrointestinal bleeding, hypersplenism, or radiographic evidence of a flow defect. The 11 stenotic shunts were treated with 100% technical success, while the remaining 9 occluded shunts were treated with 66.7% technical success. The mean number of reinterventions was 1.9 (standard deviation [SD] = 3.1) per child, which did not differ between stenotic and occluded shunts (P=0.24). Primary patency at 1-month, 6-month, 12-month and 24-months follow-up visits was 17/17 (100%), 10/16 (62.5%), 7/15 (46.7%) and 4/10 (40%), respectively. However, 100% of shunts were either primary patent or primary-assisted patent by endovascular reintervention. There were no cases of shunt occlusion following initial technical success. Finally, the median freedom from reintervention duration was 387 days (SD=821 days). CONCLUSION Dysfunctional portosystemic surgical shunts are effectively managed by endovascular methods. While many shunts require reintervention, combined primary patency and assisted primary patency rates are excellent.

Abstract
PURPOSE Few established criteria exist to prompt angiographic evaluation and intervention for surgically created splenorenal shunts (SRS). Clinical and Doppler ultrasound (DUS) imaging predictors of shunt dysfunction were evaluated in this retrospective study. MATERIALS AND METHODS Consecutive patients undergoing SRS angiography over a 10-year period were retrospectively identified. Preangiography platelet count and DUS measurements of spleen diameter, maximum splenic vein velocity, and maximum shunt velocity were assessed and compared to findings at subsequent catheter angiography. RESULTS Twenty-six SRS angiograms were performed in 16 patients. Two of the 26 procedures were excluded from analysis due to insufficient baseline preangiography clinical and DUS data. In the remaining 24 cases, significant stenosis/occlusion was confirmed at angiography in 20, whereas wide patency was seen in 4. For the 20 cases of angiographically confirmed significant stenosis/occlusion, when compared to baseline post-SRS creation to immediate preangiography evaluation there was a greater decrease in platelet count (-51.8% vs -19.4%), a greater increase in spleen diameter (+13.4% vs +3.7%), a greater increase in maximum shunt velocity (+74.7% vs +59.7%), and a greater decrease in splenic vein velocity (-25.0% vs -18.5%). CONCLUSION Clinical evidence of splenic sequestration and DUS finding of increased maximum shunt velocity correlate with angiographic findings of SRS dysfunction and could be used to help predict the need for shunt intervention.

Abstract
BACKGROUND Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are non-cirrhotic vascular causes of portal hypertension (PHT). Variceal bleed and splenomegaly are the commonest presentations. AIM The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO. RESULTS IPH and EHPVO are both characterized by normal hepatic venous pressure gradient, moderate to massive splenomegaly with preserved liver synthetic functions. While the level of block in IPH is presinusoidal, in EHPVO it is at prehepatic level. Infections, autoimmunity, drugs, immunodeficiency and prothrombotic states are possible etiological agents in IPH. Contrastingly in EHPVO, prothrombotic disorders and local factors around the portal vein are the incriminating factors. Diagnosis is often clinical, supported by simple radiological tools. Natural history is defined by episodes of variceal bleed and symptoms related to enlarged spleen. Growth failure, portal biliopathy and minimal hepatic encephalopathy are additional concerns in EHPVO. Long-term survival is reasonably good with endoscopic surveillance; however, parenchymal extinction leading to decompensation is seen in a minority of patients in both the disorders. Surgical shunts revert the complications secondary to PHT. Meso-Rex shunt has become the standard surgery in children with EHPVO. CONCLUSION This review gives a detailed summary of these two vascular conditions of liver-IPH and EHPVO. Further research is needed to understand the pathogenesis and natural history of these disorders.
