A splenic arteriovenous fistula (AVF) is an uncommon splenic vascular disease which can be congenital or acquired. A 40yr old woman, without any history of chronic liver disease, presented with non-specific pain abdomen, underwent contrast-enhanced CT and was diagnosed to have a splenic AVF with multiple intervening venous aneurysms and early filling of the portal vein. The vascular abnormality was successfully treated with a combined percutaneous glue embolisation and endovascular balloon-assisted coil embolisation...

BACKGROUND: Hepatic artery aneurysms (HAAs) exhibit a notable risk of rupture, with both true aneurysms and pseudoaneurysms being exceptionally uncommon (incidence rate approximately 2 per 100,000). Symptoms include epigastric and right upper quadrant pain, jaundice, and potentially life-threatening bleeding upon rupture. This bleeding can extend into the portal vein, hepatic vein, biliary system, or abdominal cavity. While existing literature lacks reports of delayed post-therapeutic complications, this case report discusses a 27-year-old female who developed a pseudoaneurysm six months after bilateral biliary drain insertion, underscoring the potential for delayed complications...

INTRODUCTION: Arteriovenous fistula (AVF) rarely occurs in the portal venous system. Aetiologies include iatrogenic, surgical, and penetrating trauma of the abdomen. Clinical manifestations of superior mesenteric portal arteriovenous fistula (SMPAVF) are right heart failure, mesenteric ischaemia, or signs of portal hypertension. REPORT: The case of a 42 year old man with a history of Crohn's disease who had a delayed symptomatic mesenteric portal AVF, occurring 20 years after ileocecal resection, which was subsequently managed by endovascular approach is reported...

Visceral venous aneurysms are exceedingly rare clinical entities reported in the literature. Venous aneurysms are usually acquired in origin, with most often portal hypertension as the underlying pathology. Most venous aneurysms are incidental findings on imaging. Complications of venous aneurysms like rupture with catastrophic outcomes had been reported. However, no clear guidelines exist regarding the management of portal venous aneurysms as most of the data is available only from case reports. Here, we report a rare finding of fusiform superior mesenteric vein (SMV) aneurysm with arteriovenous communication and portal vein thrombosis in the background of non-cirrhotic portal hypertension...

INTRODUCTION: Venous aneurysms are rare, so their natural history is not fully understood. Indications for treatment are often determined by the location and size of the aneurysm; however, considering the scarcity of data, there are no specific recommendations. Surgery is the mainstay for venous aneurysm treatment, but some authors reported successful endovascular treatment. We intend to describe our experience with this type of rare disorder. METHODS: A post hoc observational study of a prospectively maintained registry including consecutive patients admitted with the diagnosis of a venous aneurysm at different locations between January 2007 and September 2021...

Extrahepatic portal vein aneurysm (PVA) is a rare condition in which the extrahepatic portal vein is partially dilated into a sac-like or spindle-like shape. Usually, patients are followed, but surgery is considered in cases of rupture, thrombus, or enlargement. We report a case of thrombus formation in an extrahepatic portal vein aneurysm following trauma that resulted in regression of the aneurysm and extrahepatic portal vein occlusion. Immediately after the trauma, ultrasonography showed moderately hyperechoic structures and comet signs along the vessel wall of the aneurysm and turbulent blood flow in the aneurysm, like in a whirlpool...

Splenic arteriovenous fistulas (SAVFs) are rare vascular anomalies, which have a described association with splenic artery aneurysms. Treatment options include surgical fistula excision, splenectomy, or percutaneous embolization. Here we present a unique case of endovascular repair of a splenic arteriovenous fistula (SAVFs) associated with a splenic aneurysm. A patient with past medical history of early-stage invasive lobular carcinoma was referred to our interventional radiology practice to discuss an incidentally discovered splenic "vascular malformation" discovered during magnetic resonance imaging of the abdomen and pelvis...

BACKGROUND: Hypersplenism, portal hypertension, and ascites have been seen after liver transplants. Patients are usually treated medically with refractory patients potentially undergoing splenectomy. Splenic artery embolism (SAE) is an alternative that can be performed to limit the surgical intervention that may have the benefit of improving portal hypertension. Few studies have studied the effect on main portal vein (MPV) velocities and hepatic artery resistive indices (HARIs) which may be beneficial as markers of portal hypertension...

Vessel segmentation is crucial in many medical image applications, such as detecting coronary stenoses, retinal vessel diseases and brain aneurysms. However, achieving high pixel-wise accuracy, complete topology structure and robustness to various contrast variations are critical and challenging, and most existing methods focus only on achieving one or two of these aspects. In this paper, we present a novel approach, the affinity feature strengthening network (AFN), which jointly models geometry and refines pixel-wise segmentation features using a contrast-insensitive, multiscale affinity approach...

Hepatic arterioportal fistulae are abnormal communications between the hepatic artery and portal vein. They are reported to be congenital or acquired secondary to trauma, iatrogenic procedures, hepatic cirrhosis, and hepatocellular carcinoma, but less likely to occur spontaneously. Extrahepatic portal venous obstruction (EHPVO) can lead to pre-hepatic portal hypertension. A spontaneous superimposed hepatic arterioportal fistula can lead to pre-sinusoidal portal hypertension, further exacerbating its physiology...

Portal vein aneurysm (PVA) is a rare vascular abnormality, representing 3% of all venous aneurysms in the human body, and is not well understood. It can be congenital or acquired, located mainly at the level of confluence, main trunk, branches and bifurcation. A PVA as an abnormality of the portal venous system was first reported in 1956 by Barzilai and Kleckner. A review from 2015 entitled "Portal vein aneurysm: What to know" considered fewer than 200 cases. In the last seven years, there has been an increase in the number of PVAs diagnosed thanks to routine abdominal imaging...

Portal venous aneurysms (PVAs) are a rare venous aneurysms. The mean diameter of a healthy portal vein varies considerably, with maximum diameter of 15 mm in healthy subjects and 19 mm in cirrhotic patients. The presentation varies; they could come with abdominal pain or more often as an incident imaging finding. Although risk factors like portal hypertension and liver cirrhosis have been highlighted, the aetiology remains to be clarified. PVA may be associated with various complications: thrombosis, aneurysmal rupture, inferior vena cava obstruction or duodenal compression...

Behçet syndrome is a rare, chronic inflammatory disease of unknown aetiopathogenesis, most commonly presenting with mucocutaneous and ocular manifestations. Vascular involvement, most frequently superficial vein and deep vein thrombosis, can occur in up to 50% of patients with Behçet syndrome. Venous thrombosis at atypical sites (inferior and superior vena cava, suprahepatic veins with Budd-Chiari syndrome, portal vein, cerebral sinuses and right atrium and/or ventricle) and arterial involvement (mostly in situ thrombosis and aneurysms of the pulmonary arteries, as well as aneurysms of the abdominal aorta, and peripheral and visceral arteries) are also unique features of Behçet syndrome...

This is a case of a 61-year-old female who presented to our hospital with liver dysfunction without any symptoms. She was diagnosed with splenic arteriovenous fistula. About 8 months later, she visited the hospital again due to abdominal distention and diarrhea. Computerized tomography (CT) revealed splenic aneurysm, dilated splenic vein enhanced in the arterial phase, ascites, and intestinal edema. We considered that these findings were caused by portal hypertension due to splenic arteriovenous fistula. The splenic aneurysm was managed with coil embolization...
