Introduction
Abdominal aortic aneurysms (AAAs) with intraluminal thrombus (ILT) are suggested to be more prone to rupture than AAAs without. Prior studies indicate that the von Willebrand factor (vWf) plays a role in the formation of ILT since a positive correlation between ILT volume and vWf has been shown. vWf mediates the tethering of platelets at sites of endothelial injury, and the protease ADAMTS-13 cleaves larger forms of vWf, thus counteracting the thrombosis cascade and maintaining haemostatic balance. When investigating the largest quantifiable thrombus in the human body, it was hypothesised that circulating ADAMTS-13 activity may be associated with ILT size in patients with AAA and the aim was to explore this potential relationship using 3D contrast enhanced ultrasound (3D-CEUS) for ILT volume determination.
Report
In this retrospective, exploratory study, 60 patients with AAA were evaluated, and the association between ILT volume and thickness and ADAMTS-13 was estimated using 3D-CEUS. ADAMTS-13 activity was measured in plasma samples obtained the same day. No association between ILT volume (r = −0.03, p = 0.84) or ILT thickness (r = 0.02, p = 0.87) and ADAMTS-13 activity was found. Likewise, when subdividing the group into lowest and highest 50% of ADAMTS-13 activity, the half with the lowest ADAMTS-13 activity (mean ILT volume ±standard deviation [SD]: 32 ± 34 mL) did not differ from the half with the highest ADAMTS-13 activity (43 ± 24 mL) when comparing ILT volume (p = 0.172, F = 2.95) and thickness (p = 0.070).
Discussion
After evaluating the largest quantifiable intraluminal thrombus in the vasculature, it was concluded that, surprisingly, circulating ADAMTS-13 activity seems unrelated to ILT formation in AAA.

Introduction
Acute limb ischaemia resulting from foreign body embolisation is an infrequent yet critical complication associated with vascular closure devices (VCDs). Despite the widespread use of VCDs, rare complications such as fragment emboli pose unique challenges, necessitating heightened clinical awareness. This case report presents a case of acute limb ischaemia caused by a VCD malfunction following an endovascular procedure.
Report
A 70 year old male who was diagnosed with a severe claudication of the lower extremity (Rutherford III) due to right common iliac stenosis, underwent angioplasty using a FemoSeal (Terumo Ltd., Surrey, UK) to close the right femoral artery access. Two weeks later, the patient presented with acute lower limb ischaemia due to a right popliteal–tibial occlusion. Emergency surgical thrombo-embolectomy was successfully performed from a medial popliteal approach, and the thrombus, which contained a polymer disc from the VCD at its distal end, was completely removed.
Discussion
Despite VCDs being proven safe and efficient, rare complications such as fragment emboli can occur, and physicians should be aware of the possible delayed onset of symptoms. Moreover, the radiolucent nature of the polymer disc in a FemoSeal complicates diagnostic imaging. While endovascular approaches exist, open surgery is a safe and effective strategy for retrieving fragments and treating the patient in acute limb ischaemia cases.
Conclusion
Physicians should remain vigilant for embolic risks associated with vascular closure devices, even with suitable anatomy and following guidelines, especially considering the trend toward early ambulation and discharge.

Objective
Due to its video based approach, YouTube has become a widely accessed educational resource for patients and trainees. This systematic review characterised and evaluated the peer reviewed literature investigating YouTube as a source of patient or trainee education in vascular surgery.
Data sources
A comprehensive literature search was conducted using EMBASE, MEDLINE, and Ovid HealthStar from inception until 19 January 2023. All primary studies and conference abstracts evaluating YouTube as a source of vascular surgery education were included.
Review methods
Video educational quality was analysed across several factors, including pathology, video audience, and length.
Results
Overall, 24 studies were identified examining 3 221 videos with 123.1 hours of content and 37.1 million views. Studies primarily examined YouTube videos on diabetic foot care (7/24, 29%), peripheral arterial disease (3/24, 13%), carotid artery stenosis (3/24, 13%), varicose veins (3/24, 13%), and abdominal aortic aneurysm (2/24, 8%). Video educational quality was analysed using standardised assessment tools, author generated scoring systems, or global author reported assessment of quality. Six studies assessed videos for trainee education, while 18 studies evaluated videos for patient education. Among the 20 studies which reported on the overall quality of educational content, 10/20 studies deemed it poor, and 10/20 studies considered it fair, with 53% of studies noting poor educational quality for videos intended for patients and 40% of studies noting poor educational quality in videos intended for trainees. Poor quality videos had more views than fair quality videos (mean 27 348, 95% CI 15 154–39 543 views vs. 11 372, 95% CI 3 115–19 629 views, p = .030).
Conclusion
The overall educational quality of YouTube videos for vascular surgery patient and trainee education is suboptimal. There is significant heterogeneity in the quality assessment tools used in their evaluation. A standardised approach to online education with a consistent quality assessment tool is required to better support online patient and trainee education in vascular surgery.
