Mesenteric bypass grafts are uncommon but clinically significant findings that sonographers may encounter in routine practice. When identified, confidence in recognising graft anatomy and assessing patency is essential for safe patient management.
Presented from the perspective of an early career sonographer in a major tertiary vascular surgery department, this session provides a practical overview of the most common mesenteric bypass configurations seen at the RBWH and why they are performed. The focus will be on a structured duplex approach: identifying inflow and outflow vessels, tracking the graft, assessing anastomoses, and interpreting Doppler findings in context.
Common technical challenges and red flags suggestive of graft stenosis or failure will be highlighted, along with guidance on appropriate escalation and reporting. Attendees will leave with a clear, systematic framework to approach mesenteric bypass grafts confidently in community and mixed practice settings.

Post-thrombotic syndrome (PTS) is a common long-term complication of deep vein thrombosis that is frequently underdiagnosed. This presentation will provide an overview of the pathophysiology and incidence of PTS, with a focus on its ultrasound features. Particular attention will be given to patients who present with recurrent or persistent leg swelling following a prior DVT, in whom PTS is often overlooked. This session aims to increase sonographer awareness of PTS and highlight the importance of considering it during post-DVT lower limb assessments.

This presentation highlights the critical role of multidisciplinary collaboration in successful limb preservation programs. Effective limb salvage requires close coordination among vascular surgery, endovascular specialists, podiatry, wound care, endocrine, others, AND the vascular laboratory.

Special emphasis is placed on the vascular laboratory as an integral component of the limb preservation team, providing high-quality pre- and post-operative duplex ultrasound to guide decision-making, assess physiologic success, and monitor patients longitudinally. Duplex surveillance supports early detection of hemodynamic compromise, informs timely reintervention, and contributes to improved wound healing and limb-salvage outcomes.

This session emphasizes how structured collaboration and consistent vascular imaging protocols enhance communication across disciplines and strengthen comprehensive limb preservation strategies.
