Thirty-Day Outcomes of Fenestrated and Chimney Endovascular Repair and Open Repair of Juxtarenal, Pararenal, and Suprarenal Abdominal Aortic Aneurysms Using National Surgical Quality Initiative Program Database (2012-2016).

Background:: Fenestrated endovascular repair (FEVAR) and chimney endovascular repair (ChEVAR) endovascular repair offer a less invasive alternative to open aortic repair (OAR) in managing juxtarenal, pararenal, and suprarenal abdominal aortic aneurysms (AAAs). The aim of this study is to evaluate the 30-day postoperative outcomes following endovascular and open repair of nonruptured AAA involving the renal vessels.

Study Design:: All patients undergoing endovascular (FEVAR and ChEVAR) and open repair of juxtarenal, pararenal, and suprarenal AAA in National Surgical Quality Improvement Program database from 2012 to 2016 were included.

Statin intensity and postoperative mortality following open repair of intact abdominal aortic aneurysm.

Background: There is a lack of evidence for the association between intensive statin therapy and outcomes following vascular surgery. The aim of this study was to evaluate the association between perioperative statin intensity and in-hospital mortality following open abdominal aortic aneurysm (AAA) repair.

Methods: Patients undergoing open AAA repair between 2009 and 2015 were identified from the Premier Healthcare Database.

Outcomes and cost of fenestrated versus standard endovascular repair of intact abdominal aortic aneurysm in the United States.

Background: Fenestrated endovascular aneurysm repair (FEVAR) has expanded the indications of this minimally invasive procedure to include patients with pararenal aneurysms. The actual cost of this relatively newer technology compared with standard endovascular aneurysm repair (EVAR) has not been studied before. Thus, the aim of this study was to analyze in-hospital costs and adverse outcomes in patients undergoing FEVAR vs EVAR for intact abdominal aortic aneurysms (AAAs).

Comparison of the Cost of Drug-Eluting Stents versus Bare Metal Stents in the Treatment of Critical Limb Ischemia in the United States.

Background: Despite significant technical advancement in the last decade, the durability of endovascular management of critical limb ischemia (CLI) remains highly debatable. Drug-eluting stents (DESs) are being popularized for the management of CLI after its precedent success in coronary intervention. Initial reports on the durability of DES are promising.

Transcarotid artery stenting for carotid artery pseudoaneurysm using flow reversal technique.

Carotid artery pseudoaneurysm results mostly from direct trauma, prior endarterectomy, prior dissection, radiation, and infections. There are many different surgical and endovascular treatment options for repair, and the choice of treatment depends on patient-, surgeon-, and institute-related factors. Studies have reported the efficacy of various endovascular techniques for aneurysm repair, including stent graft placement and coil embolization, with promising short- and long-term outcomes.

Outcomes and cost of open versus endovascular repair of intact thoracoabdominal aortic aneurysm.

Objective: Many previous studies have evaluated the outcomes of open and endovascular repair of thoracoabdominal aortic aneurysms (TAAAs). However, little is known about the differences in cost of these procedures and the potential factors driving these differences. The aim of this study was to evaluate the outcomes and cost of open aortic repair (OAR) vs endovascular repair of intact TAAA.

Role of antiplatelet therapy in the durability of hemodialysis access.

Background: Antiplatelet therapy (APT) is often used on anecdotal grounds to improve vascular access patency. The aim of this study was to assess the role of APT in hemodialysis (HD) patients undergoing arteriovenous fistula (AVF) or graft (AVG) placement.

Methods: All patients in a large HD vascular qualitative initiative database (2011-2017) were included and divided into no antiplatelet therapy (no-APT) vs.

Octogenarians Undergoing Open Repair Have Higher Mortality Compared with Fenestrated Endovascular Repair of Intact Abdominal Aortic Aneurysms Involving the Visceral Vessels.

Background: Prior studies have shown that octogenarians have a higher risk of mortality than nonoctogenarians undergoing open aneurysm repair (OAR) and endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). Fenestrated endovascular aneurysm repair (F-EVAR) was approved by the Food and Drug Administration (FDA) in 2012 and has been used as a less invasive approach to treat patients with suboptimal neck anatomy with favorable outcomes compared with traditional OAR. The aim of the study is to compare 30-day outcomes of F-EVAR versus OAR in octogenarians undergoing repair of AAA involving the visceral vessels in the United States.

A prospective randomized study of bovine carotid artery biologic graft and expanded polytetrafluoroethylene for permanent hemodialysis access.

Objective: Arteriovenous grafts (AVGs) remain reliable substitutes for permanent hemodialysis access in scenarios that preclude the placement of native arteriovenous fistulas (AVFs). The majority of AVGs are constructed of expanded polytetrafluoroethylene (ePTFE), which is relatively inexpensive and readily available, but synthetic AVGs have poor patency rates. On the other hand, biologic grafts confer an advantage by virtue of their inherent similarity to the native human vasculature.
