Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian Societies of Vascular and Endovascular Surgery (SICVE) and Medical and Interventional Radiology (SIRM).

The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended.

Peripheral use of detachable coils: expanding the boundaries of embolization.

Percutaneous embolization was introduced in the mid-'70s and is now an established therapeutic procedure in current medical practice. With the use of improved imaging techniques, smaller profile catheters and new tools, embolization boundaries are significantly expanded in the last decades. Detachable coils were initially introduced in neuroradiology and are now part of the everyday peripheral embolization armamentarium. Purpose of this review article is to present an overview of the expanded possibilities that this novel material is offering in the field of peripheral embolization procedures.
