BACKGROUND AND AIM: Prognostic scoring systems (PSS) have not been validated in children with chronic Budd-Chiari syndrome (BCS). We aimed to analyse the long-term outcome of radiological intervention (RI) and validate the PSS in children. METHODS: Chronic BCS children were analysed in four subgroups: SI: successful intervention (primary or secondary stent patency) b) PO: poor outcome (refractory stent block or requirement of liver transplantation), c) NU: naïve unintervened (awaiting RI) and d) DBI: died before intervention...

The routine dissection of a male body revealed multiple anatomical variations of the celiac trunk and hepatic artery vascularization. The origin of the celiac trunk was on the left side of the abdominal aorta, next to the T12-L1 intervertebral disk. The celiac trunk gave off five branches: the left inferior phrenic artery, the left gastric artery, the accessory right hepatic artery, the common hepatic artery and the splenic artery (the last two arteries had a common origin in a hepatosplenic trunk). A right branch detached off the left gastric artery and anastomosed with the hepatic artery proper...

Vascular access for haemodialysis is key in renal patients both due to its associated morbidity and mortality and due to its impact on quality of life. The process, from the creation and maintenance of vascular access to the treatment of its complications, represents a challenge when it comes to decision-making, due to the complexity of the existing disease and the diversity of the specialities involved. With a view to finding a common approach, the Spanish Multidisciplinary Group on Vascular Access (GEMAV), which includes experts from the five scientific societies involved (nephrology [S...

Transcatheter arterial or venous embolization has been widely used to address solid tumors by occluding the tumor-feeding vessels. It is also performed to treat portosystemic shunts and to stop bleeding by repair of the site of trauma. Commonly used embolic materials are gelatin sponges, coils, beads, and liquid agents such as absolute ethanol, histoacyryl, and onyx. In the field of interventional radiology, embolotherapy is performed routinely. Liquid embolization agents have different characteristics. Their coagulation time, the inflammatory reaction of the vascular wall or surrounding tissue, and their adhesion to the vascular wall vary...

Central venous catheters (CVCs) have an important role in the management of critically ill patients. In contrast to the immediate complications after CVC insertion, the late complications were difficult to be noticed without high suspicion despite their life-threatening outcome. We report a rare but fatal delayed vascular perforation occurring after 4 days of left-sided hemodialysis catheter insertion. A 74-year-old male with septic shock was treated with continuous renal replacement therapy (CRRT) and recovered smoothly during hospitalization...

Aneurysmal bone cysts (ABC) are benign bone tumors, which are highly vascularized. The main course of treatment is curettage followed by bone grafting or cement insertion. Still recurrence remains a main problem for patients. Denosumab is a monoclonal antibody, which acts as an inhibitor of the RANK/RANKL pathway, diminishing bone turnover. Recent case reports have shown that Denosumab can be a promising therapeutic agent for people suffering from therapy-resistant ABC. We report the case of a 35-year-old female patient presenting with a pronounced ABC of the pelvis...

RATIONALE: Brain arteriovenous malformations (AVMs) are congenital vascular abnormalities involving abnormal connections between arteries and veins. In clinical practice, imaging studies help evaluate feeding arteries, niduses, draining venous systems, and coexisting complications in patients with brain AVM. They also have an impact on decision-making regarding clinical management. We applied a novel non-contrast-enhanced MR angiography (MRA) technique, termed "silent MRA," for evaluating an incidental brain AVM...

PURPOSE: In women, the uterine artery is the main branch of the internal iliac artery, vascularizing most of the uterus. Knowledge of its origin and variations is essential during extensive gynaecological surgery and interventional radiological procedures. We aimed to investigate its origin and explore its anatomical variations by three-dimensional (3D) reconstructed computed tomography (CT) angiography. METHODS: This was a retrospective, monocentric observational study involving CT scans of the abdomen and lower limbs of women < 50 years old with 3D reconstructed CT images of the internal and external iliac arterial axes...

Occlusion balloon catheters of 5.2- or 6-French have been used for a few decades in various endovascular treatments of body trunk vascular lesions. However, these catheters may be difficult to place in cases of excessive vessel tortuosity, small vessels, and anatomic complexity. Recently, the introduction of the double lumen microballoon catheters for body trunk vascular lesions has allowed operators to advance them into more distal, smaller, and more tortuous vessels. Since the launch of the first generation microballoon catheters onto the market in Japan in 2011, the microballoon catheters have evolved and are now generally available for clinical use...

BACKGROUND: Adequate haemodialysis (HD) in people with end-stage kidney disease (ESKD) is reliant upon establishment of vascular access, which may consist of arteriovenous fistula, arteriovenous graft, or central venous catheters (CVC). Although discouraged due to high rates of infectious and thrombotic complications as well as technical issues that limit their life span, CVC have the significant advantage of being immediately usable and are the only means of vascular access in a significant number of patients...

Thoracic endovascular aortic repair (TEVAR) has undergone rapid evolution and is now applied to a range of aortic pathologies. Imaging plays a vital role in the pre- and postintervention assessment of TEVAR patients. Accurate characterization of pathology and evaluation for high-risk anatomic features are necessary in the planning phase, and careful assessment for graft stability, aortic lumen diameter, and presence of endoleak are paramount in the follow-up period. CTA is the imaging modality of choice for pre- and postintervention assessment, and MRA is an acceptable alternative depending on patient stability and graft composition...

Renovascular hypertension is the most common type of secondary hypertension and is estimated to have a prevalence between 0.5% and 5% of the general hypertensive population, and an even higher prevalence among patients with severe hypertension and end-stage renal disease, approaching 25% in elderly dialysis patients. Investigation for renal artery stenosis is appropriate when clinical presentation suggests secondary hypertension rather than primary hypertension, when there is not another known cause of secondary hypertension, and when intervention would be carried out if a significant renal artery stenosis were identified...

Iliac artery occlusive disease can present as a sudden-onset acute thrombotic or thromboembolic event or as a chronic progressive atherosclerotic process that presents as claudication progressing to rest pain. Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease...
