Laser fenestration and shape memory polymer embolization of type II endoleaks Open
The present series yielded a 6-month freedom from AAA growth in approximately 43% of patients. Refractory T2ELs represent a complex subset of patients with aneurysmal disease and, with future procedural refinements, SMP embolization holds …

Characterizing changes in abdominal aortic aneurysms using principal wall strain ultrasound elastography Open
Introduction Aortic principal wall strain is a biomechanical parameter correlated with aneurysm growth rate that affects abdominal aortic aneurysm (AAA) stability. Characterize changes in pressure-normalized maximum mean aortic principal w…

Quantifying the effect of IMPEDE-FX packing rate and volume on pressure-normalized principal wall strain in an idealized 3D-printed aneurysm model Open
The present findings suggest that rapid, high-volume filling of IMPEDE-FX embolization plugs results in a reduction in wall /PP, independent of thrombus formation. Fully expanded embolization plugs in aggregate limit pulsatile aorti…

Cellular and enzymatic features of thrombi in humans are vascular bed dependent Open
Mechanisms behind vascular remodeling following thrombosis are unclear. Although acute arterial thrombosis in the cerebrovascular circulation has devastating consequences and requires immediate attention, the management of venous thromboem…

Feasibility of Measuring Magnetic Resonance Elastography-derived Stiffness in Human Thoracic Aorta and Aortic Dissection Phantoms Open
Type-B aor tic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional si…

Balloon-expandable covered stenting of a large right hepatic artery aneurysm Open
Hepatic artery aneurysms (HAAs) are rare visceral aneurysms with a high rupture rate. We report the case of an 88-year-old man with a 4.2-cm right HAA treated with covered stenting. Balloon-expandable covered stents effectively excluded th…

Strain concentration drives the anatomical distribution of injury in acute and chronic traumatic brain injury Open
Brain tissue injury caused by mild traumatic brain injury (mTBI) disproportionately concentrates in the midbrain, cerebellum, mesial temporal lobe, and the interface between cortex and white matter at sulcal depths. The bio-mechanical prin…

Evaluation of Varicose Vein-derived Blood Biomarkers for Venous Surveillance Open
Intervention for patients with symptomatic varicose veins is largely driven by a combination of symptoms, the magnitude of venous reflux, clinical severity scoring algorithms, and unresponsiveness to medical therapy. We evaluated the wall …

Strategies to Reduce Rates of Severe Endothermal Heat-induced Thrombosis Following Radiofrequency Ablation: A Single-center Experience Open
Endothermal heat-induced thrombosis (EHIT) is a potential complication of radiofrequency ablation (RFA). Data on effective prophylaxis of EHIT is limited. In 2018, our institution implemented strategies to decrease the incidence of EHIT. T…
View article: Stenting of a hepatic artery pseudoaneurysm rupture secondary to a celiac artery dissection
Stenting of a hepatic artery pseudoaneurysm rupture secondary to a celiac artery dissection Open
Hepatic artery (HA) pseudoaneurysm rupture is a rare and potentially lethal pathology. We present the case of a celiac artery dissection complicated by an HA pseudoaneurysm rupture that was treated successfully with endovascular stenting. …

Ultrasound elastography to quantify average percent pressure-normalized strain reduction associated with different aortic endografts in 3D-printed hydrogel phantoms Open
This brief report suggests that a 10% increase in graft oversizing leads to an approximate 5.9% reduction in /PP on average. Applied clinically, this increase may result in increased stiffness in axisymmetric vessels after EVAR. Fur…

Antiplatelet Therapy, Abdominal Aortic Aneurysm Progression, and Clinical Outcomes Open
Importance Preclinical studies suggest a potential role for aspirin in slowing abdominal aortic aneurysm (AAA) progression and preventing rupture. Evidence on the clinical benefit of aspirin in AAA from human studies is lacking. Objective …
View article: Intermediate pressure-normalized principal wall strain values are associated with increased abdominal aortic aneurysmal growth rates
Intermediate pressure-normalized principal wall strain values are associated with increased abdominal aortic aneurysmal growth rates Open
Introduction Current abdominal aortic aneurysm (AAA) assessment relies on analysis of AAA diameter and growth rate. However, evidence demonstrates that AAA pathology varies among patients and morphometric analysis alone is insufficient to …

Limb shaking transient ischemic attack secondary to innominate artery stenosis Open
Limb shaking transient ischemic attack is a rare disease manifestation typically caused by carotid stenosis but rarely caused by flow-limiting lesions involving more proximal vasculature. We demonstrate a case of limb shaking transient isc…

Glycoprotein VI is Critical for the Detection and Progression of Abdominal Aortic Aneurysms Open
A common feature in patients with abdominal aortic aneurysms (AAA) is the formation of a nonocclusive intraluminal thrombus (ILT) in regions of aortic dilation. Platelets are known to maintain hemostasis and propagate thrombosis through se…

Use of a modified proximal scalloped aortic arch endograft for the management of a type Ia endoleak after failed endovascular repair of an aortic dissection Open
In the United States, current endovascular repair of proximal arch pathology is limited by patient anatomy, and the availability of Food and Drug Administration (FDA) approved devices. Through the first FDA-authorized Compassionate Use (CU…
