Contribution of 30-day readmissions to the increasing costs of care for the diabetic foot

March 4, 2019 - 23:00
The inpatient cost of care for diabetic foot ulcers (DFUs) has been estimated to be $1.4 billion annually in the United States. We have previously demonstrated that the risk of 30-day unplanned readmission for patients with DFU is nearly 22%. Our aim was to quantify the cost of readmissions for patients admitted with DFU.

The effect of combining coronary bypass with carotid endarterectomy in patients with unrevascularized severe coronary disease

March 4, 2019 - 23:00
Management of significant carotid stenosis in those with symptomatic coronary disease remains controversial. Staged and combined carotid endarterectomy (CEA) with coronary artery bypass grafting has been described. Yet, an understanding of the additive risks of these approaches is poor. This study sought to assess outcomes in patients with clinically relevant coronary disease undergoing either isolated CEA (ICEA) or combined CEA and coronary artery bypass (concurrent coronary artery bypass [CCAB]).

Quantitative assessment of carotid plaque morphology (geometry and tissue composition) using computed tomography angiography

March 4, 2019 - 23:00
Quantification of carotid plaque morphology (geometry and tissue composition) may help stratify risk for future stroke and assess plaque progression or regression in response to medical risk factor modification. We assessed the feasibility and reliability of morphologic measurements of carotid plaques using computed tomography angiography (CTA) and determined the minimum detectable change in plaque features by this approach.

Risk factors and outcomes for bowel ischemia after open and endovascular abdominal aortic aneurysm repair

March 4, 2019 - 23:00
Bowel ischemia (BI) is a serious complication after abdominal aortic aneurysm (AAA) repair. We sought to identify the incidence and risk factors associated with the development of postoperative BI and the post-BI outcomes for patients undergoing open aortic repair (OAR) and endovascular aortic repair (EVAR) of AAAs.

Mas receptor deficiency augments angiotensin II-induced atherosclerosis and aortic aneurysm ruptures in hypercholesterolemic male mice

March 4, 2019 - 23:00
Previous studies demonstrated that deficiency of angiotensin-converting enzyme 2 (ACE2) augmented angiotensin II (AngII)-induced atherosclerosis and abdominal aortic aneurysm (AAA) formation in hypercholesterolemic mice. Effects of ACE2 deficiency could arise from increased concentrations of its substrate, AngII, or decreased concentrations of its product, angiotensin-(1-7) [Ang-(1-7)]. Infusion of Ang-(1-7), a Mas receptor (MasR) ligand, to hypercholesterolemic male mice reduced AngII-induced atherosclerosis, suggesting a protective role of the Ang-(1-7)/MasR axis.

Fenestrated endovascular aneurysm repair and open surgical repair for the treatment of juxtarenal aortic aneurysms

March 4, 2019 - 23:00
The objective of this study was to compare surgical risk and early and late mortality of patients treated for anatomically classified juxtarenal aortic aneurysms (JRAs) by fenestrated endovascular aneurysm repair (F-EVAR) or open surgical repair (OSR) during a period when the two treatments were available and to validate an institutional algorithm for JRA repair.

False lumen embolization in chronic aortic dissection promotes thoracic aortic remodeling at midterm follow-up

March 4, 2019 - 23:00
Failure of thoracic endovascular aortic repair (TEVAR) in chronic aortic dissections can be partially explained by retrograde false lumen (FL) flow through distal re-entry tears. After implantation of a thoracic stent graft, FL thrombosis occurs in less than 50% of the cases. The objectives of this study were to describe the feasibility and outcomes of FL embolization in patients with chronic aortic dissections.

Endosuture aneurysm repair in patients treated with Endurant II/IIs in conjunction with Heli-FX EndoAnchor implants for short-neck abdominal aortic aneurysm

March 4, 2019 - 23:00
Endovascular repair of abdominal aortic aneurysm (AAA) remains a challenging clinical scenario when there is a short or nonexistent segment of healthy infrarenal aorta. This study sought to determine the safety and effectiveness of endosuture aneurysm repair (ESAR) using the Endurant II/IIs endograft (Medtronic Vascular, Santa Rosa, Calif) in conjunction with Heli-FX EndoAnchors (Medtronic Vascular) in the treatment of short-neck AAA.

Multidisciplinary clinics reduce treatment costs and improve patient outcomes in diabetic foot disease

March 4, 2019 - 23:00
Diabetic foot disease poses a significant and rising financial burden on health care systems worldwide. This study investigated the effect of a new multidisciplinary diabetic foot clinic (MDDFC) in a large tertiary hospital on patient outcomes and treatment cost.

The JOTEC iliac branch device for exclusion of hypogastric artery aneurysms—ABRAHAM study

March 4, 2019 - 23:00
Hypogastric artery aneurysms (HAAs) are rare but life-threatening in cases of rupture. Open or endovascular techniques traditionally aimed at occluding the hypogastric artery (HA) have considerable risk of pelvic ischemia. Iliac branch devices (IBDs) are indicated for aortoiliac aneurysms; however, they have also been used lately for HAAs. Currently, there are no reports about patient outcomes focusing on HAA therapy using IBDs. We retrospectively analyzed early and midterm outcomes using IBDs for HAAs.

Partial aneurysmectomy for treatment of autologous hemodialysis fistula aneurysm is safe and effective

March 4, 2019 - 23:00
The purpose of this study was to evaluate the outcome and the factors associated with stenosis after treatment using partial aneurysmectomy for aneurysm in autologous arteriovenous fistulas.

Prognostic implications of diagnosing frailty and sarcopenia in vascular surgery practice

March 4, 2019 - 23:00
Frailty and sarcopenia are related but independent conditions commonly diagnosed in older patients that can be used to assess their ability to tolerate the stress of major vascular surgery. For surgical decision-making, however, it is important to know the prognostic implications associated with each of these conditions. The study was designed to assess the association of frailty and sarcopenia phenotypes with long-term survival of patients undergoing surgical and nonsurgical management of vascular disease.

Long-term durability of Oakes salvage procedure to preserve Brescia-Cimino arteriovenous fistula

March 1, 2019 - 23:00
In 2002, Oakes et al described a novel procedure designed to salvage the distal cephalic venous outflow of a Brescia-Cimino fistula by placing a prosthetic graft between the brachial artery in the antecubital space and the cephalic vein at the wrist. In this fashion, the more proximal veins were saved for future procedures. Their approach was reported and found to be successful in the short term, but the long-term durability of the Oakes procedure has not been described. This study aimed to determine the long-term primary, primary-assisted, and secondary patency rates of the brachial to distal cephalic vein Oakes procedure.

Management of type B aortic dissection with an isolated left vertebral artery

March 1, 2019 - 23:00
The objective of this study was to report our single-center experience of thoracic endovascular aortic repair (TEVAR) and concomitant procedures in patients with type B aortic dissection (TBAD) with an isolated left vertebral artery (ILVA) and the early to midterm outcomes in these patients.

Variation in the elective management of small abdominal aortic aneurysms and physician practice patterns

March 1, 2019 - 23:00
Recent vascular societal guidelines have recommended an abdominal aortic aneurysm (AAA) size threshold for elective intervention; however, limited data have documented how well these AAA diameter benchmarks are being met. The objective of this study was to analyze variation in management of AAAs based on diameter and to determine the physician's rationale for intervention on small AAAs in relation to recommended treatment guidelines.

Geometric changes over time in bridging stents after branched and fenestrated endovascular repair for thoracoabdominal aneurysm

March 1, 2019 - 23:00
The objective of this study was to assess long-term durability of bridging stents in branched and combined branched and fenestrated endovascular aneurysm repair (B/F-EVAR) for thoracoabdominal aortic aneurysm (TAAA) and pararenal abdominal aortic aneurysm.

Stenting of superior mesenteric and celiac arteries does not increase complication rates after fenestrated-branched endovascular aneurysm repair

March 1, 2019 - 23:00
This study compared complications in patients undergoing fenestrated-branched endovascular aneurysm repair (F-BEVAR) without and with stenting of the superior mesenteric artery (SMA) or celiac artery (CA), with particular attention to the length of coverage above the CA.

Hybrid surgery for bilateral lower extremity inflow revascularization

March 1, 2019 - 23:00
Aortobifemoral (ABF) bypass is the preferred method of bilateral inflow revascularization, with axillobifemoral (AXBF) bypass reserved for high-risk patients. Hybrid (HYB) surgery in the form of femorofemoral bypass and retrograde endovascular aortoiliac intervention is increasingly being used to achieve the same goal. This study compared the perioperative outcomes of HYB surgery with traditional surgery for bilateral inflow revascularization.

A new “angle” on aortic neck angulation measurement

March 1, 2019 - 23:00
Infrarenal aortic neck angulation is one of the most powerful predictors of endovascular aneurysm repair failure. Whereas the “gold standard” to measure this angle is three-dimensional (3D) reconstruction and centerline measurement, many surgeons rely on estimations of angulation based on two-dimensional (2D) views of computed tomography imaging. Unfortunately, these views do not accurately represent the true angle, particularly if aortic angulation is oblique to the standard views. In response to this issue, our group has developed a novel trigonometric formula that uses coronal and sagittal measured angles to calculate the true angle.

Snuffbox arteriovenous fistulas have similar outcomes and patency as wrist arteriovenous fistulas

March 1, 2019 - 23:00
Radial artery-based wrist arteriovenous fistulas (AVFs) are commonly created as an initial upper extremity arteriovenous access. A more distal access site, such as the anatomic snuffbox AVF, can also be created. Although much has been written about wrist AVFs, outcomes of snuffbox AVFs are unclear. Our goal was to compare perioperative and midterm outcomes between these two types of distal access.
