Flow-diverter treatment for renal artery aneurysms: One-year follow-up of a multicentric preliminary experience.

PURPOSE Renal artery aneurysms (RAAs) are rare in the general population, although the true incidence and natural history remain elusive. Conventional endovascular therapies such as coil embolization or covered stent graft may cause sidebranches occlusion, leading to organ infarction. Flow-diverters (FD) have been firstly designed to treat cerebrovascular aneurysms, but their use may be useful to treat complex RAAs presenting sidebraches arising from aneurysmal sac.

Uterine Myomas: Endovascular Treatment.

Uterine fibroids embolization is a safe and effective organ sparing treatment for fibroid-related symptoms based on a broad range of published evidence including randomized-controlled trials. Indication to treatment is usually the presence of symptomatic uterine fibroids. In this review, a systematic search of journal articles relevant to the treatment of symptomatic uterine fibroids was conducted, with a special focus on the indication to treatment, technique, procedural outcomes and pain control.

Sortilin levels correlate with major cardiovascular events of diabetic patients with peripheral artery disease following revascularization: a prospective study.

Background: Peripheral artery disease (PAD) represents one of the most relevant vascular complications of type 2 diabetes mellitus (T2DM). Moreover, T2DM patients suffering from PAD have an increased risk of major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Sortilin, a protein involved in apolipoproteins trafficking, is associated with lower limb PAD in T2DM patients.

Renal artery embolization for iatrogenic renal vascular injuries management: 5 years' experience.

Objective: Evaluate the efficacy and safety of renal artery embolization (RAE) for iatrogenic renal vascular injuries (IRVI) management at Fondazione Policlinico Universitario "A. Gemelli" IRCCS, in the last 5 years.

Methods: Retrospective analysis of all RAE procedures performed from January 2013 to December 2017.

Pulmonary arteriovenous malformations: what the interventional radiologist needs to know.

Pulmonary arteriovenous malformations (PAVMs) or fistulas are rare direct pathological connections between pulmonary arterial and venous circulation. Most of PAVMs are congenital and closely associated with hereditary hemorrhagic telangiectasia, but acquired PAVMs have also been described in the literature. Diagnosis of PAVMs is a priority for clinicians, in order to prevent potentially fatal events such as cerebrovascular stroke, systemic septic embolization, hemoptysis and hemothorax.

ACE I allele is associated with more severe portal hypertension in patients with liver cirrhosis: A pilot study.

Background: In liver cirrhosis, the renin-angiotensin-aldosterone system is involved in the pathogenesis of portal hypertension. Its effector, angiotensin II, is generated by angiotensin-converting enzyme (ACE). Serum ACE levels are affected by I/D polymorphism of its gene, with alleles I and D being associated, respectively, with lesser and greater activity of the enzyme.

Uterine fibroid embolization efficacy and safety: 15 years experience in an elevated turnout rate center.

Objective: To evaluate effectiveness and safety of UFE as alternative to surgery, in treatment of uterine fibromatosis.

Methods/materials: 255 patients (aged 26-55) with symptomatic UF, indication for surgery, followed in our center (2000-2014), single or multiple fibroids, pain and/or functional/compressive disorders, underwent embolization: injection of PVA particles (150-900 μm) from distal portion of uterine arteries (ascending section). Primary end-point: flow-stop distally to injection site, disappearance of lesion design, preservation of flow in main trunk of UA.

Comparison of CT and MR angiography in evaluation of peripheral arterial disease before endovascular intervention.

Background: Multidetector computed tomography angiography (MDCTA) and magnetic resonance angiography (MRA) are accurate techniques for selecting patients with peripheral arterial disease for surgical and endovascular treatment. No studies in the literature have directly compared MDCTA and MRA to establish which one should be employed, in patients suitable for both techniques, before endovascular treatment.

Purpose: To compare diagnostic performance of MDCTA vs MRA before endovascular intervention.
