Wire wrap involving the celiac and superior mesenteric artery portals of the GORE EXCLUDER thoracoabdominal branch endoprosthesis: A multi-center case series.

The GORE EXCLUDER thoracoabdominal branch endoprosthesis is the only commercially available, off-the-shelf stent graft for endovascular repair of thoracoabdominal aortic aneurysms in the United States. The design features preloaded guidewires, eliminating the need to separately catheterize each branch portal. However, wire wrapping of the target vessel cannulation wires can cause technical difficulties during catheterization and presents challenges to bridge stent delivery and deployment, leading to bridge stent wrapping.

A national census for the off-label treatment of complex aortic aneurysms.

Objective: Despite regulatory challenges, device availability, and rapidly expanding techniques, off-label endovascular repair of complex aortic aneurysms (cAAs) has expanded in the past decade. Given the lack of United States Food and Drug Administration-approved endovascular technology to treat cAAs, we performed a national census to better understand volume and current practice patterns in the United States.

Methods: Targeted sampling identified vascular surgeons with experience in off-label endovascular repair of cAAs.

Outcomes Following Urgent Fenestrated-Branched Endovascular Repair for Pararenal and Thoracoabdominal Aortic Aneurysms.

Background: To evaluate outcomes following urgent or emergent fenestrated-branched endovascular aortic repair (F-BEVAR) for pararenal (PRA) and thoracoabdominal aortic aneurysms (TAAA) in patients who are considered high-risk for open repair.

Methods: A retrospective, single institution evaluation of outcomes following F-BEVAR of symptomatic, rapidly enlarging, or ruptured PRA or TAAA treated with physician modified endograft (PMEG) and company manufactured devices (CMD). Outcomes were technical success, 30-day morbidity and mortality, and 1 year aortic related outcomes.

Adventitial cystic disease of the common femoral vein: an unusual cause of lower extremity swelling and review of the literature.

We report the case of a 61-year-old man who had presented with acute unilateral limb swelling. Computed tomography venography and duplex ultrasound demonstrated compression of the right common femoral vein by a common femoral vein adventitial cyst. Before intervention, the patient had developed an acute deep vein thrombosis of the right common femoral vein and great saphenous vein.

Development of quantitative structure-activity relationships for explanatory modeling of fast reacting (meth)acrylate monomers bearing novel functionality.

The photoinitiated polymerization of (meth)acrylate monomers bearing novel carbamate functionality exhibits significantly greater reaction rate when compared to more traditional acrylate monomers undergoing similar polymerization. This unusually fast reactivity has been the subject of much investigation. In order to suggest an explanatory mechanism for the enhanced polymerization rates we have conducted quantitative structure-activity relationship investigations of these novel monomers.
