Aortic Disease Activity in Patients With Endoleak After Endovascular Aneurysm Repair
Aortic aneurysm disease activity can be assessed using sodium [18F] fluoride positron emission tomography and increased aortic sodium [18F] fluoride uptake is associated with a higher rate of abdominal aortic aneurysm expansion and adverse clinical events. We aimed to establish whether increased aortic disease activity is associated with patients who developed an endoleak after endovascular aneurysm repair (EVAR). (Source: Journal of Vascular Surgery)

‘Malignant’ Type 2 Endoleak: An Entity With a Worse Prognosis?
Persistent type 2 endoleak (T2EL) has been associated with enlargement of the aneurysmal sac and even rupture. Typical findings of a T2EL consist of a nidus within the thrombus, usually with one or more inflow and outflow arteries. However, the ‘malignant’ T2EL (MT2EL) we are describing is also associated with enlargement of the thrombosed sac, but without a nidus. On the contrary, MT2EL present a contrasted reinforcement of the wall, and the diffuse and irregularly stained thrombus by computed tomography angiography (CTA; Fig.1).

Applicability of the Anatomic Severity Grading Score in Endovascular Abdominal Aortic Aneurysm Repair
Endovascular aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysms (AAAs), but concerns about its long-term effectiveness due to complications and reinterventions persist. The Society for Vascular Surgery (SVS) introduced the Anatomic Severity Grading (ASG) score to standardize patients' anatomical presentations, and analyze surgical outcomes. This retrospective study aimed to validate the ASG score as a predictor of EVAR complications. (Source: Journal of Vascular Surgery)

Type IV Ehlers Danlos: Abdominal Aortic Rupture After Endovascular Repair of Common Iliac Artery Aneurysms
Ehlers-Danlos Syndrome (EDS) is a rare genetic disorder impacting collagen production, leading to diverse symptoms and complications across various organs. While classical EDS seldom involves vascular issues, patients with type IV EDS (vEDS) face severe risks such as vascular aneurysm, dissection, and rupture. This form of EDS is relatively rare, accounting for less than 4% of all EDS cases, and it poses significant challenges in terms of surgical interventions. (Source: Journal of Vascular Surgery)

Biodesign: Creating and Validating an EVAR Explantation Device
Endovascular abdominal aortic aneurysm repair (EVAR) and its recent advances have improved the outcomes of abdominal aortic aneurysm (AAA) repair with lower morbidity and mortality in the short term. However, endovascular stent grafts are associated with two major complications, including graft infection (10%) and endoleaks (68%) with sac expansion, both of which require multiple interventions. Graft explantation is necessary because of infection or failed endosalvage of endoleak, which are both associated with high morbidity and mortality. (Source: Journal of Vascular Surgery)

Efficacy of a Modular Imaging Algorithm for Surveillance After Endovascular Aortic Repair
Research on optimal surveillance after endovascular aneurysm repair (EVAR) has been dominated by efforts to find the single best-suited imaging modality culminating in one-size-fits-all approaches, even though treatment strategies and often endografts themselves are tailor-made to adjust for individual patients. Endoleaks are the most common finding and most common reason for re-intervention after EVAR. Therefore, imaging modalities have been primarily investigated for endoleak detection, where contrast-enhanced ultrasound (CEUS) and computed tomography angiography (CTA) repeatedly showed the highest accuracy.

Aortic Balloon Molding Technique for Infrarenal Aortic Occlusion in Treatment of Ruptured AAAs
The Ovation stent graft (Endologix) utilizes aortic balloon molding, or ABM – a novel endovascular technique in which the graft is pre-cannulated and a compliant aortic balloon is inflated at the site of the graft's sealing rings during polymer administration. This technique can be used in the setting of ruptured endovascular aneurysm repair (rEVAR), instead of advancing separate aortic balloon occlusion to provide infrarenal aortic occlusion, expedite repair and minimize time to resuscitation. We sought to assess outcomes of patients treated with this technique in the setting of rEVAR (Source: Journal of Vascular Surgery)

Case Report: Persistent Intra-abdominal Infection Resulting in Internal Iliac Artery Pseudoaneurysm Infection
Pseudoaneurysms are a punctured arterial wall with contained bleeding. The pseudoaneurysm may be caused by iatrogenic damage during catheterization procedures or open surgery, and damage to a nearby artery. Bacterial infections may also cause damage to a vessel wall. Adjacent infections to an artery my cause arterial wall damage and a subsequent pseudoaneurysm. (Source: Journal of Vascular Surgery)

3D-Printed Abdominal Aortic Aneurysm (AAA) Model for Hemodynamic Evaluation: A Pilot Study
Treatment of abdominal aortic aneurysms (AAAs) depends on the maximum diameter of the aneurysm. However, the pathophysiology and hemodynamics of AAA development and growth are still poorly understood. We aimed to develop a prototype of a patient-specific, AAA hemodynamic simulation model to find out patient-specific hemodynamic characteristics. (Source: Journal of Vascular Surgery)

Parallel Grafts to Treat Aorto-iliac Aneurysms: How to Size the Common Iliac Stent Graft
Aortoiliac aneurysms (AIA) occur unilaterally or bilaterally. Up to 40% of abdominal aortic aneurysms (AAAs) are associated with iliac artery aneurysms.[1] One technique to preserve internal iliac artery (IIA) blood flow is the sandwich technique (ST),[2] using two covered stents – one to the IIA, and the second to the external iliac artery (EIA) – which are placed inside the common iliac stent graft (the main limb of endovascular aneurysm repair; Fig 1.) It is very important to choose the correct sizing of common iliac stent grafts to decrease risk of type 3 endoleak.[3 ] (Source: Journal of Vascular Surgery)
