Hydatid disease of the liver with portal vein invasion mimicking portal vein thrombosis

Hydatid cyst disease is a zoonosis caused by the parasite Echinococcus. It may infest any organ of the body, but it most frequently involves the liver, lungs, and nervous system. Portal vein involvement by hydatid cyst disease is extremely rare with only five cases published in the English literature to our knowledge. We present the ultrasonography (US) and computed tomography (CT) findings of a 77-year-old male with hydatid disease of the liver with portal vein invasion mimicking portal vein thrombosis. Colour Doppler US confirmed the lack of blood flow within the portal vein and stigmata of cavernomatosis. CT clearly demonstrated a communication between the multiloculated lesion and the portal vein and the multiple daughter vesicles obstructing the portal vein. The consideration of this complication will make it possible to distinguish this entity from portal vein thrombosis and, thus, the management of the patients with hydatid cyst disease particulary in endemic regions.     

Etiology,presenting features and outcome of children with non-cirrhotic portal vein thrombosis: A multicentre national study

ObjectivesNon-cirrhotic portal vein thrombosis (PVT) is a main cause of portal hypertension in children. We describe the characteristics at presentation and outcome of a cohort of patients with PVT to determine clinical features and predictors of outcome.MethodsWe recorded: (1) Associated factors: prematurity, congenital malformations, neonatal illnesses, umbilical vein catheterization (UVC), deep infections, surgery; (2) congenital and acquired prothrombotic disorders; (3) features at last follow up including survival rate and need for surgery.Results187 patients, mean age at diagnosis 4 ± 3.7 years, had a history of prematurity (61%); UVC (65%); neonatal illnesses (79%). The diagnosis followed the detection of splenomegaly (40%), gastrointestinal bleeding (36%), hypersplenism (6%), or was incidental (18%). Of 71 patients who had endoscopy at presentation 62 (87%) had oesophageal varices. After 11.3 years’ follow up 63 (34%) required surgery or TIPS. Ten-year survival rate was 98%, with 90% shunt patency. Spleen size, variceal bleeding and hypersplenism at presentation were predictors of surgery or TIPS (p < 0.05).ConclusionPVT is associated with congenital and acquired co-morbidities. History of prematurity, neonatal illnesses and UVC should lead to rule out PVT. Large spleen, variceal bleeding and hypersplenism at presentation predict the need for eventual surgery in a third of cases.

Biliopancreatic fistula with portal vein thrombosis caused by a pancreatic pseudocyst

We encountered a very rare case of biliopancreatic fistula with portal vein thrombosis caused by pancreatic pseudocyst. A 57-year-old man was referred to our hospital because of abdominal pain, obstructive jaundice, and portal vein thrombosis due to acute pancreatitis. Computed tomography showed a 7-cm-diameter pseudocyst around the superior mesenteric vein extending towards the pancreatic head, dilatation of the intrahepatic bile duct, and portal vein thrombosis. Endoscopic retrograde pancreatography revealed a main pancreatic duct with a pseudocyst communicating with the common bile duct. After pancreatic sphincterotomy, a 7-F tube stent was endoscopically placed into the pseudocyst. However, a 6-F nasobiliary tube could not be inserted into the bile duct because the fistula had a tight stenosis. Subsequently, the patient’s abdominal pain improved, the pancreatic cyst disappeared, and the serum amylase level normalized. Two months after the endoscopic retrograde cholangiopancreatography, percutaneous transhepatic biliary drainage was required because the patient’s jaundice became aggravated. Two weeks after the choledochojejunostomy, the patient left the hospital in good condition. A follow-up computed tomography showed cavernous transformation of the portal vein and no pancreatic pseudocyst. The patient remains asymptomatic for 2 years and 7 months after surgery. Biliary drainage may be necessary for biliopancreatic fistula with obstructive jaundice in addition to pancreatic cyst drainage. Biliopancreatic fistula can be treated by endoscopic procedure in some cases; however, surgical treatment should be required in cases that are impossible to insert a biliary stent because of hard stricture.     

Clinical outcome of portal vein thrombosis in patients with digestive cancers: A large AGEO multicenter study

IntroductionManagement of portal vein thrombosis (PVT) in cancer patients remains discussed.AimsThe objective of this multicenter retrospective study was to investigate the management and outcome of PVT in patients with digestive cancers other than hepatocellular carcinoma (HCC).MethodMain inclusion criteria were trunk or branch PVT in patients with locally advanced or metastatic digestive cancers. Predictive factors of bleeding and overall survival (OS) were evaluated in univariate and multivariate analysis.ResultsBetween 2012 and 2016, 118 patients with PVT and digestive cancers were identified. The majority had a pancreatic cancer (50%). Sixty-six percent of patients had trunk PVT location. Endoscopic screening of portal hypertension was performed in only 7 patients (1%) and 5 had esophageal varices. Gastrointestinal bleeding occurred in 22 patients (19%) and 12 patient deaths (17%) were related to a gastrointestinal hemorrhage. Metastatic disease (HR = 2.83 [95%CI 1.47–5.43], p < 0.01) and gastrointestinal hemorrhage (HR = 1.68 [95%CI 1.01–2.78], p = 0.04) were associated with OS in multivariate analysis. Only trunk PVT location was significantly associated with gastrointestinal hemorrhage in multivariate analysis (HR = 5.56 [95%CI 1.18–26.32], p = 0.03).ConclusionA high rate of variceal bleeding leading to death was found in this cohort. Endoscopic screening and the efficacy of prophylactic treatment of variceal bleeding remain to be evaluated in a prospective study.     

门静脉血栓介入治疗研究进展

正门静脉血栓是指门静脉主干及其分支血栓形成,可导致门静脉部分或完全性梗阻,部分门静脉血栓可以延伸至脾静脉或肠系膜上静脉。门静脉血栓的形成原因有多种,主要包括肝硬化、肿瘤、免疫系统疾病、感染、凝血功能障碍和口服避孕药物等~([1])。在肝硬化进展期或合并肿瘤患者,门静脉血栓的发生率更高~([2,3])。据统计,肝硬化并发门静脉高压患者门静脉血栓发生率约为0.6%～15.8%~([4])。伴有门静脉血栓的肝硬化患者发生消化道出血的风险更高~([5])。门静脉血栓形成所导致的临床表现差异较大,轻症患者可无任何临床症状,常常在随访过程中被发现。     

A case of portal vein thrombosis associated with acute cholecystitis/pancreatitis or coincidence

BACKGROUND: Portal vein thrombosis (PVT) is complex and risk factors include local precipitating factors and acquired and inherited factors. It occurs secondary to abdominal malignancy, infection or surgical intervention. PVT is commonly forgotten as a possible cause of abdominal pain. The clinical picture may vary but abdominal pain and low grade fever are the most characteristic picture. METHODS: A 58-year-old male patient was admitted to our hospital complaining of abdominal pain for three days. CT scan revealed an edematous area around the portal vein. Doppler ultrasonography showed evidence of a portal vein thrombosis. RESULTS: PVT can be diagnosed with CT and Doppler ultrasonography. Fresh thrombus can be undetected by sonography because of the low echogenity but can be recognised by color Doppler ultrasonography. Treatment ranges from observation and bowel rest to surgical resection of bowel. CONCLUSIONS: When we suspect a case of PVT, it should be treated at an early stage to prevent being lost in a diagnostic dilemma. The immediate use of anticoagulant could be important in preventing serious consequences of PVT.     

肝硬化患者门静脉血栓形成危险因素的Logistic回归分析

目的研究肝硬化患者门静脉血栓（PVT）形成的相关危险因素。方法回顾性分析我院消化内科2007—2008年确诊的肝硬化患者80例,其中19例肝硬化PVT患者作为血栓组,61例肝硬化非血栓患者作为对照组,收集相关临床资料,对可能影响PVT形成的因素进行单因素分析和Logistic回归模型分析。结果Logistic回归模型分析结果显示,血浆D-二聚体、门静脉宽度（MPV）、血小板（PLT）是肝硬化患者PVT形成的独立危险因素（P值分别为0.003、0.012、0.036）。结论肝硬化患者应注意监测血浆D-二聚体、门静脉宽度、血小板等指标,以便早期预防和发现PVT的形成。     

肝硬化并发门静脉血栓研究进展

肝硬化并发门静脉血栓（Portal vein thrombosis,PVT）将增加肝硬化并发症的发生率。由于PVT可与上消化道出血同时发生,增加了治疗的难度。PVT形成的主要原因是门静脉血流速度降低。目前,治疗PVT仍以药物为主,研究表明抗凝治疗并不增加消化道出血的风险,因此对于有适应症的患者,在食管胃静脉曲张经治疗消失后,应及时针对PVT进行治疗。部分脾动脉栓塞患者,在治疗后常规给予抗凝处理可减少门静脉血栓的发生。在治疗过程中,早期诊断、抗凝治疗的监测指标、肝素用量、预防复发方面仍有较多问题等待解决。

Transhepatic fibrinolysis of mesenteric and portal vein thrombosis in a patient with uIterative colitis: A case report

AIM: To present a case of acute mesenteric and portal vein thrombosis treated with thrombolytic therapy in a patient with ulcerative colitis in acute phase and to review the literature on thrombolytic therapy of mesenteric-portal system. Treatment of acute portal vein thrombosis has ranged from conservative treatment with thrombolysis and anticoagulation therapy to surgical treatment with thrombectomy and/or intestinal resection. METHODS: We treated our patient with intraportal infusion of plasminogen activator and then heparin through a percutaneous transhepatic catheter. RESULTS: Thrombus resolved despite premature interruption of the thrombolytic treatment for neurological complications, which subsequently resolved. CONCLUSION: Conservative management with plasminogen activator, could be considered as a good treatment for patients with acute porto-mesenteric thrombosis.     

肝硬化并发门静脉血栓临床表现和诊断进展

正门静脉血栓形成(portal vein thrombosis,PVT)是晚期肝硬化的常见并发症之一~([1])。近年来,文献报道PVT在肝硬化患者的患病率为0.6%～26.0%~([2,3])。PVT的临床表现差异很大,可无症状,也可表现为致命性并发症,如静脉曲张破裂出血、肠梗死等。随着影像学技术的不断提高,越来越多不同程度的PVT被诊断出来~([4～6])。1肝硬化并发PVT的临床特点1.1急性PVT PVT的临床表现取决于血栓形成的     

Outcome of living donor liver transplantation in patients with preoperative portal vein thrombosis

Background and study aimsPortal vein thrombosis (PVT) is no longer an absolute contraindication for living donor liver transplantation (LDLT). This study aimed to assess the short-term outcomes of LDLT and compare the 1-year survival rates between patients with and without preoperative PVT.Patients and methodsThis combined prospective and retrospective cohort study was conducted on patients who underwent LDLT at Ain Shams Centre for Organ Transplantation (ASCOT) between 2008 and 2020. The study included 60 patients with PVT and 60 patients without PVT. The two groups were compared in terms of preoperative data, operative details, postoperative complications, and 1-year survival.ResultsMost patients with PVT were Child C (65%) and had higher model for end stage liver disease scores (16.23 ± 4.03) compared to the non-PVT group (13.9 ± 4.5). The PVT group showed longer cold ischemic time (CIT), hospital stay, and intensive care unit stay and significantly shorter 1-year survival rate (63.3%) compared to the non-PVT group (86.7%) (P = 0.003). Those with PVT grades I, II, and III had 1-year survival rates of 72.5%, 50%, and 40%, respectively.ConclusionPreoperative PVT reduces the 1-year survival after transplantation, with patients with higher PVT grades exhibiting lower 1-year survival. LDLT for PVT still remains challenging and requires further studies.
