Purpose: The aim of this study was to analyse our 8 years of experience with endovascular treatment of visceral aneurysms and pseudoaneurysms.
Materials And Methods: From January 2002 to September 2009, we used an endovascular approach to treat 30 patients (22 men, eight women) affected by aneurysm (n=18) or pseudoaneurysm (n=13) of the splenic (n=11), hepatic (n=6), renal (n=5), pancreaticoduodenal (n=3), left gastric (n=2), gastroduodenal (n=1), rectal (n=1) or middle colic (n=1) arteries and the coeliac axis (n=1). Of these, 26/31 were treated with metal coils, 3/31 with Cardiatis multilayer stent, 1/31 with a coated stent and 1/31 with coils and Amplatzer plug. Procedures were performed electively in 10/30 cases and during haemorrhage in 20/30 cases. Follow-up was performed clinically (cessation of bleeding) and at 1, 6 and 12 months by colour-Doppler ultrasound (CDUS) and computed tomography (CT) angiography.
Results: In 31/31 aneurysms and pseudoaneurysms we obtained immediate exclusion. In four patients with aneurysm and in four with pseudoaneurysm, parenchymal ischaemia occurred; one was treated with surgical splenectomy. One patient with pseudoaneurysm of the coeliac axis died 10 days later because of new bleeding. During follow-up, all aneurysms and pseudoaneurysms remained excluded.
Conclusions: Percutaneous treatment is effective and safe, with a small number of complications, especially when compared with traditional surgery.

We present the case of a 74-year-old female patient with a 50 mm ascending aortic aneurysm who underwent ascending aorta replacement. During routine open heart surgery, suboptimal flow in the cardiopulmonary bypass circuit, led to the discovery of a type B aortic dissection with substantial flow in the false lumen. Conservative management was chosen, focusing on blood pressure control in the ICU.

Background: Intrasaccular flow diversion using the woven endobridge device (WEB; MicroVention, Aliso Viejo, CA, USA) for the treatment of intracranial aneurysms has demonstrated large scale safety and efficacy. However, limitations arise from its structural configuration, restricting its application to specific aneurysm sizes and shapes.
Technique Overview: We introduce the CUPCAKE technique, a combination of conventional coiling followed by WEB intrasaccular flow disruption in select cases of atypical aneurysms with technically challenging morphology not typically treatable by WEB alone.

Purpose: We aimed to validate a clinically available artificial intelligence (AI) model to assist general radiologists in the detection of intracranial aneurysm (IA) in a multi-reader multi-case (MRMC) study, and to explore its performance in routine clinical settings.
Methods: Two distinct cohorts of head CT angiography (CTA) data were assembled to validate an AI model. Cohort 1, comprising gold-standard consecutive CTA cases, was used in an MRMC study involving six board-certified general radiologists.

Traumatic aneurysms represent less than 1 percent of intracranial aneurysms and middle meningeal artery pseudoaneurysms are even rare. Traumatic aneurysms are usually pseudoaneurysms formed by the rupture of all the layers of the vessel wall. They are associated with high mortality as they can present as epidural, subdural, and rarely intraparenchymal hematoma.
