Introduction: Iatrogenic femoral artery pseudoaneurysm is a recognised complication of transfemoral arterial access and is associated with a spectrum of potential adverse outcomes, including pain, haemorrhage, infection, and limb-threatening complications. With the increasing volume of cardiac and endovascular procedures performed worldwide, accurate and timely diagnosis of pseudoaneurysm has become increasingly important in guiding appropriate management and intervention.
Duplex ultrasound is widely accepted as the first-line imaging modality for the assessment of suspected femoral artery pseudoaneurysm. It provides a rapid, non-invasive means of confirming the diagnosis, characterising pseudoaneurysm morphology, and identifying associated complications such as arteriovenous fistula, venous thrombosis, or surrounding haematoma. Key sonographic features include the presence of a patent pseudoaneurysm sac, identification of the neck, and demonstration of the characteristic “to-and-fro” Doppler waveform. These findings directly influence treatment decisions, including conservative management, ultrasound-guided thrombin injection, or surgical intervention. Despite its central role in diagnosis and management, the quality and consistency of ultrasound assessment for groin pseudoaneurysm may vary depending on operator experience, technical factors, and reporting practices, and there remains a lack of standardised national guidance regarding optimal imaging protocols.
Methods and results: This presentation will review the current literature surrounding ultrasound diagnosis and management of iatrogenic femoral artery pseudoaneurysms. It will also draw on experience from a large tertiary institution, including findings from a retrospective quality audit performed, supported by illustrative cases, to highlight practical imaging techniques, common pitfalls, and optimisation strategies that reinforce best practice in vascular ultrasound assessment.

Introduction: Ultrasound remains the primary tool for aneurysm screening and surveillance; however, there still exists differing assessment and measurement techniques within the field.
Methods: This talk will focus on the ultrasound imaging techniques of an aneurysm prior to diameter measurement – what makes a given image diagnostic and what makes a series of images complete. The primary focus will be techniques which ensure adequate appreciation of the typically irregular shape of an aneurysm, and correct probe alignment to the aneurysm midline.
Results and Conclusion: Performing a comprehensive, multiapproach assessment of aneurysms and ensuring careful alignment to the aneurysm midline will improve an aneurysm diameter measurement assessment.
