Pulmonary arteriovenous malformations (PAVMs) cause cerebral abscess and ischemic stroke due to paradoxical emboli, risks that are increasingly recognized. We report the evolving placement of thoracic surgery in multi-disciplinary team management of PAVMs that were sporadic or associated with hereditary hemorrhagic telangiectasia. From 1983 to 2006, all patients receiving elective treatment had embolization.

However, US has limited sensitivity for early-stage HCC, particularly in overweight cohorts, where hepatic visualisation is often inadequate. Currently there are no robust imaging surveillance strategies in patients with inadequate US visualisation.

- The review analyzes the effectiveness of zinc oxide-based materials versus glass-ionomer cement as temporary fillings during endodontic treatment, focusing on their sealing properties in extracted teeth.
- Seven clinical trials were examined, revealing variability in sealing ability, with glass-ionomer cement performing better for single-rooted teeth, while zinc oxide materials also showed good results.
- Although zinc oxide materials have advantages such as consistent application, concerns about dye penetration tests not fully capturing bacterial leakage risk highlight the need for more clinical research.
Background: Bronchial artery embolization (BAE) using particles is an established treatment for hemoptysis. The use of polyvinyl alcohol (PVA) with a particle size of 300 µm or larger is thought to reduce the risk of non-target embolization but may result in more proximal vessel occlusion than is ideal, resulting in a high rate of early recurrent hemorrhage.
Objective: This study evaluates the safety and efficacy of BAE using PVA particles with a size of less than 300 µm.
Adrenal Vein Sampling: Does the Location of the Non-adrenal Venous Sample Matter?
Cardiovasc Intervent Radiol
February 2024
Purpose: Adrenal vein sampling (AVS) is used to lateralise and differentiate unilateral from bilateral aldosterone production in primary aldosteronism. The adrenal venous samples are standardised to a peripheral or low inferior vena cava (IVC) sample and compared. It is unknown whether the location of the non-adrenal sample affects the results.
