Fenestrated endovascular aneurysm repair is associated with lower perioperative morbidity and mortality compared with open repair for complex abdominal aortic aneurysms

9 hours 10 min ago
The Zenith Fenestrated Endovascular Graft (ZFEN; Cook Medical, Bloomington, Ind) has expanded the anatomic eligibility of endovascular aneurysm repair (EVAR) for complex abdominal aortic aneurysms (AAAs). Current data on ZFEN mainly consist of single-institution experiences and show conflicting results. Therefore, we compared perioperative outcomes after repair using ZFEN with open complex AAA repair and infrarenal EVAR in a nationwide multicenter registry.

Using bifurcated endoprosthesis after iliac artery recanalization for concomitant abdominal aortic aneurysm and chronic total occlusions of access routes

9 hours 10 min ago
Concurrent abdominal aortic aneurysm (AAA) and unilateral iliac occlusion is a challenge in the implantation of bifurcated stent grafts (BFGs). The endovascular approach is less invasive than open surgery; the aortouni-iliac (AUI) graft with crossover femorofemoral bypass (CFFB) has many problems associated with extra-anatomic reconstruction. We attempted endovascular aneurysm repair (EVAR) using BFGs in such cases and evaluated the outcomes.

Discussion

9 hours 10 min ago
Dr Nathan Orr (Lexington, Ky). I would like to congratulate the authors on an excellent presentation and manuscript as they begin to sort through the incidence and characteristics of secondary aortic interventions after thoracic endovascular aortic repair (TEVAR) for type B aortic dissections. As you have just heard, secondary aortic interventions are commonly required in this cohort, with an overall incidence of 27%. Further, this is fairly consistent for all comers, with relatively few predictors of increased incidence.

Implications of secondary aortic intervention after thoracic endovascular aortic repair for acute and chronic type B dissection

9 hours 10 min ago
Thoracic endovascular aortic repair (TEVAR) has become a mainstay of therapy for acute and chronic type B aortic dissection (TBAD). Dynamic aortic morphologic changes, untreated dissected aorta, and persistent false lumen perfusion have significant consequences for reintervention after TEVAR for TBAD. However, few reports contrast differences in secondary aortic intervention (SAI) after TEVAR for TBAD or describe their influence on mortality. This analysis examined incidence, timing, and types of SAI after TEVAR for acute and chronic TBAD and determined their impact on survival.

The objective of this study was to evaluate the incidence, timing, and potential risk factors of late endograft migration after thoracic endovascular aortic repair (TEVAR).

Addition of proximal intervention to carotid endarterectomy increases risk of stroke and death

9 hours 10 min ago
Adding ipsilateral, proximal endovascular (IPE) intervention to carotid endarterectomy (CEA) for the treatment of tandem bifurcation and supra-aortic trunk disease is controversial. Some suggest that this combined strategy (CEA + IPE) confers no risk over isolated CEA (ICEA). Others disagree, reserving CEA + IPE for symptomatic patients. Using the Vascular Quality Initiative (VQI), this study assessed the effect of adding IPE to CEA on stroke and death risk. We further weighed CEA + IPE outcomes in the context of symptomatic status and Society for Vascular Surgery guidelines.

Management and outcome of 597 wartime penetrating lower extremity arterial injuries from an international military cohort

February 17, 2019 - 23:00
Vascular injury is a leading cause of death and disability in military and civilian settings. Most wartime and an increasing amount of civilian vascular trauma arises from penetrating mechanisms of injury due to gunshot or explosion. The objective of this study was to provide a comprehensive examination of penetrating lower extremity arterial injury and to characterize long-term limb salvage and differences related to mechanisms of injury.

C-reactive protein as a prognostic risk factor for loss of arteriovenous fistula patency in hemodialyzed patients

February 17, 2019 - 23:00
Inflammation is a cardiovascular risk factor in hemodialysis patients, but its influence on vascular access patency is still debatable. Our prospective study investigated this issue.

A systematic review of patch angioplasty versus primary closure for carotid endarterectomy

February 17, 2019 - 23:00
Guidelines recommend routine patching after carotid endarterectomy (CEA) on the basis of a lower restenosis rate and presumed lower procedural stroke rate than with primary repair. Underlying evidence is based on studies performed decades ago with perioperative care that significantly differed from current standards. Recent studies raise doubt about routine patching and have suggested that a more selective approach to patch closure (PAC) might be noninferior for procedural safety and long-term stroke prevention.

The structural atrophy of the aneurysm wall in secondary expanding aortic aneurysms with endoleak type II

February 17, 2019 - 23:00
Abdominal aortic aneurysm (AAA) has an age-dependent prevalence of 2% to 11% and is a leading cause of death in men aged >65 years if not treated surgically. Today, endovascular aneurysm repair (EVAR) is performed in up to 80% of elective cases and 60% of ruptured cases. Although EVAR improves perioperative, early, and midterm outcomes, it is associated with specific complications, especially endoleaks (ELs). Type II EL occurs in up to 30% of procedures; however, aneurysm sac expansion and rupture are rare, and currently nothing is known about the morphologic changes in this condition.

Anesthesia type determines risk of cerebral infarction after carotid endarterectomy

February 17, 2019 - 23:00
Silent and symptomatic cerebral infarctions occur in up to 34% of patients after carotid endarterectomy (CEA). This prospective study compared the risk of new brain infarctions detected by magnetic resonance imaging (MRI) in patients with internal carotid artery stenosis undergoing CEA with local anesthesia (LA) vs general anesthesia (GA).

Cocaine use is associated with worse outcomes in patients treated with thoracic endovascular repair for type B aortic dissection

To describe and compare the clinical and anatomical characteristics and outcomes of patients with and without known cocaine use who underwent thoracic endovascular repair for type B aortic dissections.

Follow-up imaging of traumatic vertebral artery dissections is unnecessary in asymptomatic patients

February 17, 2019 - 23:00
Routine computed tomography (CT) imaging in trauma patients has led to increased recognition of blunt vertebral artery injuries (BVIs). We sought to determine the prevalence of strokes, injury progression, and need for intervention in patients with BVI.

Flow dynamics of type II endoleaks can determine sac expansion after endovascular aneurysm repair using four-dimensional flow-sensitive magnetic resonance imaging analysis

February 17, 2019 - 23:00
The objective of this study was to investigate the hemodynamic parameters of type II endoleaks (T2ELs) to predict sac expansion using four-dimensional flow-sensitive magnetic resonance imaging (4D-flow MRI) analysis.

Transforming growth factor β neutralization finely tunes macrophage phenotype in elastase-induced abdominal aortic aneurysm and is associated with an increase of arginase 1 expression in the aorta

February 17, 2019 - 23:00
Macrophages play a critical role in the initiation and progression of abdominal aortic aneurysm (AAA) and are classically distinguished into M1 “proinflammatory” and M2 “anti-inflammatory” macrophages. Topical application of elastase associated with transforming growth factor β (TGF-β) systemic neutralization reproduces the main pathologic features of human AAA, offering a new model to investigate their role. The aim of this study was to investigate whether macrophages contribute to the expression of canonical M1/M2 markers in the aorta in the AAA model induced by elastase and systemic blockade of TGF-β and whether blocking of TGF-β activity affects macrophage phenotype and the expression of the M2 marker arginase 1 (ARG1).

Factors relating to the publication rate of abstracts presented from 2012 to 2015 at the Society for Vascular Surgery Annual Meeting

February 17, 2019 - 23:00
The Society for Vascular Surgery's Annual Meeting acts as a means of disseminating research findings among vascular surgeons through the presentation of research abstracts. Following presentation at the meeting, research is often compiled into a full-text manuscript and submitted to a peer-reviewed journal. However, not all abstracts accepted to the Vascular Annual Meeting (VAM) eventually have a corresponding full-text publication. The objectives of this study were to establish the publication rate of abstracts presented between 2012 and 2015 to the VAM and to identify factors correlating with publication status.

Forecasting aortic aneurysm rupture: A systematic review of seasonal and atmospheric associations

February 17, 2019 - 23:00
Abdominal aortic aneurysms (AAAs) represent a significant burden of disease worldwide, and their rupture, without treatment, has an invariably high mortality rate. Whereas some risk factors for ruptured AAAs (rAAAs) are well established, such as hypertension, smoking, and female sex, the impact of seasonal and meteorologic variables is less clear. We systematically reviewed the literature to determine whether these variables are associated with rAAA.

Initial results of thoracic endovascular repair for uncomplicated type B aortic dissection involving the arch vessels using a semicustom-made thoracic fenestrated stent graft

February 17, 2019 - 23:00
Thoracic endovascular aortic repair (TEVAR) for selected type B aortic dissection (TBAD) is a standard treatment; however, TBAD involving the aortic arch is difficult to treat because of the need for arch vessel reconstruction. We report our initial results of TEVAR for uncomplicated TBAD involving the arch vessels using a semicustom-made fenestrated stent graft.

Utilization of regional versus general anesthesia and its impact on lower extremity bypass outcomes

February 17, 2019 - 23:00
Previous studies evaluating general anesthesia (GA) vs regional (epidural/spinal) anesthesia (RA) for infrainguinal bypass have produced conflicting results. The purpose of this study was to analyze the factors associated with contemporary use of RA and to determine whether it is associated with improved outcomes after infrainguinal bypass in patients with critical limb ischemia.

Cost-effectiveness analysis of endovascular versus open repair of abdominal aortic aneurysm in a high-volume center

February 14, 2019 - 23:00
Endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) is the standard treatment for anatomically suitable patients. EVAR has been associated with a lower perioperative morbidity and mortality compared with open surgical repair (OSR) at the expense of increased reinterventions and costs. We aimed to compare the outcomes of EVAR and OSR for elective AAA repair. The primary end point was cost per QALY at 3 years. Secondary end points were perioperative morbidity and mortality; freedom from reintervention; length of hospital, high-dependency unit, and intensive care unit stay; and freedom from all-cause mortality.
