Pancreatitis with Intraabdominal Venous Thrombosis as an Initial Presentation of Parathyroid Adenoma: A Rare Clinical Presentation.

BACKGROUND Benign parathyroid adenoma is a cause of hypercalcemia, which can lead to acute pancreatitis. Patients with acute pancreatitis are at risk for venous thrombosis. This report describes a 34-year-old woman with hypercalcemia due to parathyroid adenoma and acute pancreatitis associated with splenic vein and superior mesenteric vein thrombosis. CASE REPORT A previously healthy 34-year-old woman presented with severe epigastric pain that radiated to the back, associated with vomiting. Her abdominal examination was soft and lax, with epigastric and left upper quadrant tenderness. Pancreatitis with splenic and superior mesenteric veins thrombosis was diagnosed. The diagnosis was confirmed by an elevated serum lipase level and contrast-enhanced computed tomography (CT) of abdomen. Her serum calcium level was elevated. However, further workup revealed elevated parathyroid hormone (PTH) levels and radiological imaging showed parathyroid adenoma. She was diagnosed with hypercalcemia-induced pancreatitis secondary to hyperparathyroidism with intraabdominal venous thrombosis. The patient was initially treated conservatively, and later underwent parathyroidectomy after her condition was stabilized. The patient is currently in good condition, after a 2-year follow-up period. CONCLUSIONS Acute pancreatitis and thrombosis secondary to primary hyperparathyroidism (PHPT) are rare, but can lead to potentially fatal complications, especially in patients without symptoms of PHPT. This report highlights the importance of recognizing that hypercalcemia associated with parathyroid adenoma can result in acute pancreatitis, leading to hypercoagulable states and inflammation of adjacent vessels, including the splenic and mesenteric veins. To the best of our knowledge, this is second case report of acute pancreatitis with intraabdominal venous thrombosis secondary to PHPT.

Safety and effectiveness of transsplenic access for portal venous interventions: a single-center retrospective study.

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.

A new method to predict venous complications in pediatric liver transplantation: Evaluation of splenic parameters by ultrasonography.

BACKGROUND: Venous complications after pediatric liver transplantation seriously affect the survival rate of patients and grafts. At present, the diagnostic indicators have not been unified. Venous complications may cause portal hypertension, which may lead to splenomegaly and splenic vein dilatation. Therefore, the changes in spleen may be closely related to the venous complications. The purpose of this study was to explore the relationship between ultrasonic splenic parameters and venous complications and to study whether these splenic parameters can be used for the diagnosis of venous complications. METHODS: We retrospectively included pediatric patients who underwent liver transplantation and collected ultrasonic spleen parameters before, and then 1-3 days, 1-3 weeks, 1-3 months, and 4-12 months after liver transplantation. We observed whether there were portal vein or hepatic vein complications within 1 year after liver transplantation. RESULTS: Among 109 pediatric patients after liver transplantation included in our study, 11 of them suffered from portal vein complications and nine hepatic vein complications. Spleen transverse diameter, spleen longitudinal diameter, spleen portal vein diameter, spleen index, spleen transverse diameter ratio, spleen longitudinal diameter ratio, and spleen index ratio were independent risk factors of venous complications. The accuracy of spleen transverse diameter (AUROC: 0.73), spleen index (AUROC: 0.70), spleen transverse diameter ratio (AUROC: 0.71), and spleen index ratio (AUROC: 0.72) in predicting venous complications were higher than other ones. CONCLUSIONS: Ultrasonic examination is a common follow-up method for pediatric patients after liver transplantation and the application of ultrasonic spleen parameters may be helpful to monitor venous complications.

[Une combinaison très rare de thrombose veineuse et artérielle chez un patient atteint du COVID 19]. / A very rare combination of venous and arterial thrombosis in a patient with COVID-19.

COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. This epidemic has caused serious socio-economic problems worldwide, with a very high mortality rate. Several articles have been published in the literature showing the consequences of this disease on the human body. Among the most serious complications are venous and arterial thrombosis, which are rarely observed together in the same patient. In this article, we report an exceptional case of a patient with COVID-19 with the combination of intracardiac thrombus (left atrium) and venous thrombosis (splenic vein and portal trunk).

A retrospective multicentre clinical study on management of isolated splenic vein thrombosis: risks and benefits of anticoagulation.

INTRODUCTION: Isolated splenic vein thrombosis (iSVT) is a common complication of pancreatic disease. Whilst patients remain asymptomatic, there is a risk of sinistral portal hypertension and subsequent bleeding from gastric varices if recanalisation does not occur. There is wide variation of iSVT treatment, even within single centres. We report outcomes of iSVT from tertiary referral hepatobiliary and pancreatic (HPB) units including the impact of anticoagulation on recanalisation rates and subsequent variceal bleeding risk. METHODS: A retrospective cohort study including all patients diagnosed with iSVT on contrast-enhanced CT scan abdomen and pelvis between 2011 and 2019 from two institutions. Patients with both SVT and portal vein thrombosis at diagnosis and isolated splenic vein thrombosis secondary to malignancy were excluded. The outcomes of anticoagulation, recanalisation rates, risk of bleeding and progression to portal vein thrombosis were examined using CT scan abdomen and pelvis with contrast. RESULTS: Ninety-eight patients with iSVT were included, of which 39 patients received anticoagulation (40%). The most common cause of iSVT was acute pancreatitis n = 88 (90%). The recanalisation rate in the anticoagulation group was 46% vs 15% in patients receiving no anticoagulation (p = 0.0008, OR = 4.7, 95% CI 1.775 to 11.72). Upper abdominal vascular collaterals (demonstrated on CT scan angiography) were significantly less amongst patients who received anticoagulation treatment (p = 0.03, OR = 0.4, 95% CI 0.1736 to 0.9288). The overall rate of upper GI variceal-related bleeding was 3% (n = 3/98) and it was independent of anticoagulation treatment. Two of the patients received therapeutic anticoagulation. CONCLUSION: The current data supports that therapeutic anticoagulation is associated with a statistically significant increase in recanalisation rates of the splenic vein, with a subsequent reduction in radiological left-sided portal hypertension. However, all patients had a very low risk of variceal bleeding regardless of anticoagulation. The findings from this retrospective study should merit further investigation in large-scale randomised clinical trials.

A Case Report of Modified Pancreatic Transplantation With a Limited Splenic Arteriovenous Fistula to Elude Thrombosis.

In classic pancreatic transplantation, the splenic artery and vein are ligated at the tail of the pancreas graft. This leads to slowed blood flow in the splenic vein and may cause thrombosis and graft loss. In this study, a patient received a pancreas after kidney transplantation. A modified surgical technique was used in the pancreatic graft preparation. The donor splenic artery and vein were anastomosed end to end at the tail of the pancreas. The splenic artery near the anastomosis was partially ligated, and an effective diameter of 2 mm was reserved to limit arterial blood pressure and flow. The patient recovered very well. Contrasted computed tomography scans on days 11 and 88 after pancreas transplantation indicated sufficient backflow of the splenic vein. We believe that this procedure may avoid the risk of splenic vein thrombosis after pancreas transplantation. This modified technique has not been reported in clinical cases previously and may help reduce the risk of thrombosis after pancreas transplantation.

Combined transhepatic and transsplenic recanalization of chronic splenic vein occlusion to treat left-sided portal hypertension: A cases report.

RATIONALE: This report describes a unique case of a combination transhepatic and transsplenic recanalization of chronic splenic vein occlusion to treat left-sided portal hypertension (LSPH). PATIENT CONCERNS: In this case report, we report a 49-year-old male who was admitted due to LSPH causing black stools for 2 days and vomiting blood for 1 hour. DIAGNOSES: The patient has a history of multiple episodes of pancreatitis in the past. After admission, abdominal contrast-enhanced CT scan showed the appearance of pancreatitis, with extensive splenic vein occlusion and accompanied by gastric varicose veins, indicating the formation of LSPH. INTERVENTION: The patient received treatment with a combination of splenic and hepatic splenic venoplasty. OUTCOMES: Follow up for 1 year, CT and gastroscopy showed disappearance of gastric varices. LESSONS: Splenic venoplasty is an effective method for treating LSPH. When it is difficult to pass through the occluded segment of the splenic vein through a single approach, percutaneous double approach splenic venoplasty can be attempted for treatment.

Impact of radiological and pathological splenic vein involvement in patients with resectable pancreatic body or tail cancer.

PURPOSE: Several studies have reported a negative impact on survival associated with splenic vessel involvement, especially splenic artery (SpA) involvement, in patients diagnosed with pancreatic body or tail cancer. However, there is limited research on splenic vein (SpV) involvement. Therefore, we aimed to elucidate the significance of splenic vessel involvement, especially SpV involvement, in patients with resectable pancreatic body or tail cancer. METHODS: Between January 2007 and December 2021, 116 consecutive patients underwent distal pancreatectomies for pancreatic body or tail cancer. Among them, this study specifically examined 88 patients with resectable pancreatic body or tail cancer to elucidate prognostic factors using a multivariable Cox proportional analysis. The Kaplan-Meier method evaluated the impact of SpV involvement in terms of both radiological and pathological aspects and the efficacy of neoadjuvant therapy. RESULTS: Higher pre-operative carcinoembryonic antigen levels, larger tumour size, pathological SpV invasion, and non-completion of adjuvant therapy were identified as independent poor prognostic factors for overall survival (OS) and recurrence-free survival (RFS). Additionally, patients with radiological SpV encasement had significantly worse prognoses in terms of OS (p = 0.039) and RFS (p < 0.001). The sensitivity and specificity of multidetector-row computed tomography for detecting pathological SpV invasion were 81.0% and 61.2%, respectively. However, the prognostic impact of neoadjuvant therapy could not be determined, regardless of radiological SpV involvement. CONCLUSION: Radiological and pathological SpV involvement is a poor prognostic factor for patients with resectable pancreatic body or tail cancer. New innovative treatments and effective neoadjuvant therapy regimens are required for patients with SpV involvement.

Gastric Varices Rupture due to Splenic Vein Obstruction Associated with Autoimmune Pancreatitis.

A 60-year-old man with a high IgG4 level was found to have pancreatic tail enlargement on computed tomography (CT), and autoimmune pancreatitis (AIP) was confirmed by a histological diagnosis. He was treated with prednisolone for one year and seven months, at which point his treatment finished. Four months later, however, he had hematemesis from gastric varices. CT showed recurrence of pancreatic tail enlargement with obstruction of the splenic artery and vein and formation of collateral blood vessels to the gastric fornix. Endoscopic injection sclerotherapy was performed, and he underwent splenectomy. This case highlights the importance of paying attention to peripancreatic vascular abnormalities during follow-up of AIP patients.

Non-contrast-enhanced MR angiography of left gastric vein in patients with gastroesophageal varices: morphology and blood supply analysis.

OBJECTIVES: To investigate the feasibility of non-contrast-enhanced MR angiography (NCE-MRA) in evaluating the morphology and blood supply of left gastric vein (LGV) in patients with gastroesophageal varices. METHODS: Between March 2021 and October 2022, patients with gastroesophageal varices and who underwent NCE-MRA were retrospectively reviewed. In order to evaluate the blood supply of LGV, superior mesenteric vein (SMV) and splenic vein (SV) were visualized separately by using inflow-sensitive inversion recovery sequence. Two radiologists independently assessed the image quality, determined the origination and the blood supply of LGV, and measured the diameter of LGV. The origination and diameter of LGV were compared between NCE-MRA and contrast-enhanced CT. Differences in blood supply were compared between LGVs with different originations. RESULTS: A total of 53 patients were enrolled in this study and the image quality was categorized as good or excellent in 52 patients. No significant differences were observed in visualizing the origination and the diameter of LGV between NCE-MRA and contrast-enhanced CT (p > .05). The blood supply of LGV was related to its origination (p < .001). Most LGVs with SV origination were supplied by SV. If LGV was originated from the portal vein (PV), about 70% of them were supplied by both SV and SMV. Compared with LGVs with SV origination, LGVs with PV origination showed more chance to receive blood from SMV (p < .001). CONCLUSION: Non-contrast-enhanced MR angiography appears to be a reliable technique in evaluating the morphology and blood supply of LGV in patients with gastroesophageal varices. CLINICAL RELEVANCE STATEMENT: Non-contrast-enhanced MR angiography provides valuable information for the management of gastroesophageal varices. Especially, it benefits patients with renal insufficiency. KEY POINTS: • Non-contrast-enhanced MR angiography using inflow-sensitive inversion recovery technique can be used for evaluating not only morphology as CT but also blood supply of left gastric vein. • The blood supply of left gastric vein is related to its origination and left gastric vein with portal vein origination shows more chance to receive blood from superior mesenteric vein.

Risk factors for portal vein system thrombosis after partial splenic embolisation in cirrhotic patients with hypersplenism.

AIM: To determine risk factors for portal venous system thrombosis (PVST) after partial splenic artery embolisation (PSAE) in cirrhotic patients with hypersplenism. MATERIALS AND METHODS: Between March 2014 and February 2022, 428 cirrhotic patients with hypersplenism underwent partial splenic artery embolisation and from these patients 208 were enrolled and 220 were excluded. Medical records of enrolled patients were collected. Computed tomography (CT) images were reviewed by two blinded, independent radiologists. Statistical analyses were performed by using SPSS. RESULTS: Progressive PVST was observed in 18.75% (39/208) of cirrhotic patients after PSAE. No significant differences in peripheral blood counts, liver function biomarkers, and renal function were observed between the patients with progressive PVST and the patients without progressive PVST. The imaging data showed significant differences in PVST, the diameters of the portal, splenic, and superior mesenteric veins between the progressive PVST group and non-progressive PVST group. Univariate and multivariate analysis demonstrated portal vein thrombosis, spleen infarction percentage, and the diameter of the splenic vein were independent risk factors for progressive PVST. Seventeen of 173 (9.83%) patients showed new PVST; the growth of PVST was observed in 62.86% (22/35) of the patients with pre-existing PVST. Spleen infarction percentage and the diameter of the splenic vein were independent risk factors for new PVST after PSAE. CONCLUSION: The present study demonstrated portal vein thrombosis, spleen infarction percentage, and the diameter of the splenic vein were independent risk factors for PVST after PSAE in cirrhotic patients with hypersplenism.

Treatment of colonic varices and gastrointestinal bleeding by recanalization and stenting of splenic-vein-thrombosis: A case report and literature review.

BACKGROUND: Splenic vein thrombosis is a known complication of pancreatitis. It can lead to increased blood flow through mesenteric collaterals. This segmental hypertension may result in the development of colonic varices (CV) with a high risk of severe gastrointestinal bleeding. While clear guidelines for treatment are lacking, splenectomy or splenic artery embolization are often used to treat bleeding. Splenic vein stenting has been shown to be a safe option. CASE SUMMARY: A 45-year-old female patient was admitted due to recurrent gastrointestinal bleeding. She was anemic with a hemoglobin of 8.0 g/dL. As a source of bleeding, CV were identified. Computed tomography scans revealed thrombotic occlusion of the splenic vein, presumably as a result of a severe acute pancreatitis 8 years prior. In a selective angiography, a dilated mesenterial collateral leading from the spleen to enlarged vessels in the right colonic flexure and draining into the superior mesenteric vein could be confirmed. The hepatic venous pressure gradient was within normal range. In an interdisciplinary board, transhepatic recanalization of the splenic vein via balloon dilatation and consecutive stenting, as well as coiling of the aberrant veins was discussed and successfully performed. Consecutive evaluation revealed complete regression of CV and splenomegaly as well as normalization of the red blood cell count during follow-up. CONCLUSION: Recanalization and stenting of splenic vein thrombosis might be considered in patients with gastrointestinal bleeding due to CV. However, a multidisciplinary approach with a thorough workup and discussion of individualized therapeutic strategies is crucial in these difficult to treat patients.

Drainage pattern of the splenic flexure vein and its accompanying arteries using three-dimensional computed tomography angiography: a single-centre study of 600 patients.

AIM: The splenic flexure has variable vascular anatomy, and the details of the venous forms are not known. In this study, we report the flow pattern of the splenic flexure vein (SFV) and the positional relationship between the SFV and arteries such as the accessory middle colic artery (AMCA). METHODS: This was a single-centre study using preoperative enhanced CT colonography images of 600 colorectal surgery patients. CT images were reconstructed into 3D angiography. SFV was defined as a vein flowing centrally from the marginal vein of the splenic flexure visible on CT. AMCA was defined as the artery feeding the left side of the transverse colon, separate from the left branch of the middle colic artery. RESULTS: The SFV returned to the inferior mesenteric vein (IMV) in 494 cases (82.3%), the superior mesenteric vein in 51 cases (8.5%) and the splenic vein in seven cases (1.2%). The AMCA was present in 244 cases (40.7%). The AMCA branched from the superior mesenteric artery or its branches in 227 cases (93.0% of cases with existing AMCA). In the 552 cases in which the SFV returned to the IMV, superior mesenteric vein or splenic vein, the left colic artery was the most frequent artery accompanying the SFV (42.2%), followed by the AMCA (38.1%) and the left branch of the middle colic artery (14.3%). CONCLUSIONS: The most common flow pattern of the vein in the splenic flexure is from the SFV to IMV. The SFV is frequently accompanied by the left colic artery or AMCA.

Pediatric hypereosinophilic syndrome associated with liver damage, portal vein, splenic vein and superior mesenteric vein thromboses: a case report.

BACKGROUND: The hypereosinophilic syndrome (HES) is a group of rare blood disorders characterized by persistent eosinophilia and damage to multiple organs. HES can be either primary, secondary or idiopathic. Secondary HES are commonly caused by parasitic infections, allergic reactions or cancer. We described a pediatric case of HES associated with liver damage and multiple thrombi. A 12-year-old boy with eosinophilia was complicated with severe thrombocytopenia, liver damage, portal vein, splenic vein, and superior mesenteric vein thromboses. The thrombi recanalized after treatment with methylprednisolone succinate and low molecular weight heparin. No side effects appeared after 1-month. CONCLUSIONS: Corticosteroids should be used at an early stage of HES to prevent further damage to vital organs. Anticoagulants should be recommended only in cases with thrombosis which should be actively screened as a part of evaluation of end organ damage.

The effect of splenic vein diameter on the diagnosis of portal vein thrombosis.

BACKGROUND: It was still controversial that whether the increase of splenic vein (SV) diameter increased the risk of portal vein thrombosis (PVT), which was a severe disease with high mortality, in the clinic. PURPOSES: This study, using computational fluid dynamics method, aimed to investigate how the increase of SV diameter affects the portal vein hemodynamics under different anatomical and geometric features of the portal venous system, thus how it induced to PVT. METHODS: The ideal models of the portal system, including different anatomical structures according to the location of left gastric vein (LGV) and inferior mesenteric vein (IMV), and different geometric morphological parameters models were established to carry out numerical simulation in this study. In addition, the morphological parameters of real patients were measured to verify the numerical simulation results. RESULTS: First, the wall shear stress (WSS) and helicity intensity, which were closely related to the occurrence of thrombosis, gradually decreased with the increase of SV diameter in all models. However, the degree of decrease was bigger in following models: (1) the models with LGV and IMV linking to SV compared with them linking to PV; (2) the models with big angle of PV and SV compared with small angle. In addition, the morbidity of PVT was higher when LGV and IMV linked to SV rather than them linked to PV in the real patients. Moreover, the angle of PV and SV was also different between PVT and non-PVT patients (125.53° ± 16.90° vs. 115.03° ± 16.10°, p = 0.01). CONCLUSION: Whether the increase of SV diameter will result in PVT is depended on the anatomical structure of portal system and the angle between PV and SV, this is also the reason leading to the clinical controversy that the increase of SV diameter is the risk factor of PVT.

Splenic vein embolization as a feasible treatment for patients with hepatic encephalopathy related to large spontaneous splenorenal shunts.

INTRODUCTION AND OBJECTIVES: Although splenic vein embolization (SVE) has been performed for the management of patients with hepatic encephalopathy (HE) related to large spontaneous splenorenal shunts (SSRS) in recent years, its role remains poorly defined. In this study, we aimed to explore the safety and efficacy of SVE for HE patients with large SSRS. MATERIALS AND METHODS: Data from cirrhotic patients who were confirmed to have recurrent or persistent HE related to large SSRS and underwent SVE from January 2017 to April 2021 were retrospectively collected and analyzed at our center. The primary endpoints were the change of HE severity at 1 week after embolization and the recurrence of HE during the follow-up period. The secondary endpoints were procedure-related complications and changes in laboratory indicators and hepatic function (Child-Pugh score/grade and model for end-stage liver disease score). RESULTS: Of the eight cirrhotic patients included in the study, six were diagnosed with recurrent HE, and the others were diagnosed with persistent HE. Embolization success was achieved for all patients (100%), and no immediate procedure-related complications, de novo occurrence, or aggravation of symptoms related to portal hypertension were observed during the long-term follow-up. HE status was assessed at 1 week after embolization. The results demonstrated that the symptoms were mitigated in three patients and resolved completely in five patients. During the follow-up period, all patients were free of HE within 1 month after embolization, but one patient experienced the recurrence of HE within 6 months and another one experienced the recurrence of HE within 1 year. Compared with the preoperative parameters, the Child-Pugh score and grade were significantly improved at 1 week and 1 month after embolization (all P<0.05), and the serum ammonia level was significantly lower at 1 month after embolization (P<0.05). CONCLUSIONS: SVE could be considered as a feasible treatment for patients with HE related to large SSRS, but further validation is required.

Coincidence of splenic vein aneurysm and haemorrhagic cyst of the pancreas.

Pseudoaneurysm of the splenic vein is a rare entity which is associated with pancreatitis in 52 % cases. Pseudocysts of the pancreas create approximately 70 % of all cystic lesions of the pancreas. One of the most dangerous complications of pancreatic pseudocysts is bleeding into the cystic lumen. This is caused by perforation of the pseudoaneurysm of the splenic vein. Enzymatic damage of the splenic vein´s wall is the cause of pseudoaneurysm. The clinical condition varies. It can be asymptomatic or bring about haemodynamic instability. The diagnostic process of pseudoaneurysm of the splenic vein is difficult. This case study introduces a case of a 50­year­old man with the anamnesis of recurrent pancreatitis caused by alcoholism. He had abdominal pain and was diagnosed with a pseudocyst of the pancreas. Abdominal CT showed an extensive capsulated collection in the left subphrenic space, 23cm in diameter, with serosanguineous content and coagulations. The CT visualised the mass effect on the surrounding tissues and a complete deformation of the spleen. Between the collection and partially oppressed tail of the pancreas there was a venous pseudoaneurysm, 3.5cm in diameter. Considering its localization, it most probably originated from the splenic vein. Surgery was done. We did distal resection of the pancreas with a complete removal of the pseudocyst and spleen (Fig. 7, Ref. 11). Keywords: splenic vein, pseudoaneurysm, pancreatitis, pancreatic pseudocysts.

Splenic Arteriovenous Fistula Accompanied by Splenic Artery Aneurysm Associated with Acute-onset Portal Hypertension and Gastrointestinal Bleeding: Case Report and Literature Review.

Splenic arteriovenous fistula is an uncommon aetiology of portal hypertension, which has definitive treatment effectiveness and good prognosis. We report a case of portal hypertension and gastrointestinal bleeding in the absence of hepatic parenchymal disease in a 50 year-old woman with multiple pregnancies. Abdominal computed tomography and transabdominal arteriography recorded the presence of tortuous and aneurysmal splenic arteries and the premature filling of enlarged splenic veins, which are highly suggestive of splenic arteriovenous fistula. The above vascular abnormalities were successfully treated by transcatheter embolization. No recurrence or other complications were observed. In addition, a literature review concerning splenic arteriovenous fistula published in recent 30 years was performed to further our understanding of the management strategy on this entity.
