Arterial pathophysiology - what's important
11:00 AM - 11:20 AMAbstract
A fundamental understanding of atherosclerosis pathophysiology is useful for sonographers performing vascular ultrasound examinations to have, however, the depth of information available in scientific journal articles can make understanding this topic difficult.
This talk will focus on the pathogenesis of atherosclerosis development, and detail the contributions of smoking and diabetes to its formation and consequent vessel disease in the lower limb arteries.
By understanding atherosclerosis pathophysiology, and the major contributors associated with its development, sonographers can better understand the development, distribution and recurrence of lower limb atherosclerosis.

Ultrasound assessment of lower-limb bypass grafts: Are we looking at the whole picture?
12:00 PM - 12:20 PMAbstract
In recent years, although development of angioplasty treatment of arterial occlusion continues to evolve, infrainguinal bypass continues to be an integral part of vascular management of arterial disease.
This presentation will cover:
• Why infrainguinal bypasses are necessary
• Types of bypass grafts and understanding of the surgical procedure
• Surveillance program
• How pathology develops
• Assessment of graft patency and inflow / outflow vessels.
• Case studies of pathology
• How to report sonographic findings
By the end of the presentation, you should have a greater understanding of bypass grafts. How to approach and execute scanning of this region, avoid common pitfalls, and effectively report your findings.

Correlation between ankle-brachial index and pedal acceleration time in detecting lower extremity peripheral artery disease among adult patients with diabetes mellitus in a tertiary hospital
12:20 PM - 12:30 PMAbstract
Introduction: Peripheral artery disease, especially in those with type 2 diabetes mellitus (DM), contributes to higher morbidity and mortality. Although studies have established that the ankle-brachial index is the initial screening tool to diagnose PAD, it is unreliable in calcified and noncompressible arteries. Recent studies have found that measuring of pedal acceleration time (PAT) by ultrasound may be an alternative to diagnosing PAD. This study aimed to evaluate the relationship between ABI and PAT in detecting lower extremity PAD among diabetic patients.
Methods and Materials: This is a prospective cross-sectional study. A total of 42 DM adult patients were enrolled from March 2022 to November 2022, each of them with ABI and PAT measured, and their association were determined.
Results: More than 50% of the subjects had asymptomatic PAD while the rest experienced claudication, rest pain, or ulcers/gangrene. None had noncompressible arteries by ABI and none showed severe PAD by PAT. ABI of the right lower limb and PAT of the left lower limb showed significant differences amongst the stages of PAD. There was a weak negative correlation between ABI and PAT. Significant correlation was only observed between PAT of either lower limbs and the stage of PAD.
Conclusion: PAT measurement can be good alternative to detecting PAD even in patients with compressible arteries.
Take home message: PAT can be a valuable alternative to the ABI for detecting peripheral artery disease in diabetic patients, especially when ABI results are unreliable due to arterial calcification.
