Midterm and long-term follow-up in competitive athletes undergoing thoracic outlet decompression for neurogenic thoracic outlet syndrome

September 21, 2017 - 00:00
Neurogenic thoracic outlet syndrome (NTOS) results from compression of the brachial plexus by the clavicle, first rib, and scalene muscles and may develop secondary to repetitive motion of the upper extremity. Athletes routinely perform repetitive motions, and sports requiring significant arm and shoulder use may put the participant at increased risk for NTOS. Competitive athletes who develop NTOS may require first rib resection and scalenectomy (FRRS) for symptomatic relief. However, the effectiveness of FRRS has not previously been studied in this vulnerable population.

Early reintervention after open and endovascular abdominal aortic aneurysm repair is associated with high mortality

September 21, 2017 - 00:00
Although reinterventions are generally considered more common after endovascular aneurysm repair (EVAR) than after open surgical repair (OSR), less is known about reintervention in the early postoperative period. Furthermore, there are few data regarding the impact of early reintervention on 30-day mortality. We sought to evaluate the rates and types of reintervention after abdominal aortic aneurysm (AAA) repair and the impact of reintervention on postoperative mortality.

Development and validation of a score to predict life expectancy after carotid endarterectomy in asymptomatic patients

September 21, 2017 - 00:00
Recent improvement of best medical treatment for carotid stenosis has sparked a debate on the role of surgery identification of patients who may benefit from carotid endarterectomy (CEA) is crucial to avoid overtreatment. An expected 5-year postoperative survival is one of the main selection criteria. The aim of this study was the development of a score for predicting survival of asymptomatic patients after CEA.

Clinical significance of reversal of flow in the vertebral artery identified on cerebrovascular duplex ultrasound

September 18, 2017 - 00:00
Reversal of flow in the vertebral artery (RFVA) is an uncommon finding on cerebrovascular duplex ultrasound examination. The clinical significance of RFVA and the natural history of patients presenting with it are poorly understood. Our objective was to better characterize the symptoms and outcomes of patients presenting with RFVA.

Proximal radial artery arteriovenous fistula for hemodialysis vascular access

September 11, 2017 - 00:00
This study reviewed our experience with proximal radial artery-based arteriovenous fistulas (PRA-AVFs) for hemodialysis vascular access, evaluating characteristics of the patients, functional patency, risk of steal syndrome, survival of the patient, and technical considerations.

Predictors of late aortic intervention in patients with medically treated type B aortic dissection

September 11, 2017 - 00:00
Patients with medically managed type B aortic dissection (TBAD) have a high incidence of aorta-related complications over time. Whereas early thoracic endovascular aortic repair (TEVAR) to seal the entry tear can promote aortic remodeling and prevent late aneurysm formation, there are sparse data as to which patients will benefit from such therapy. The goal of this study was to identify clinical and anatomic factors that are associated with the need for subsequent aortic intervention in patients who present with uncomplicated TBAD.

Adventitial adipogenic degeneration is an unidentified contributor to aortic wall weakening in the abdominal aortic aneurysm

September 11, 2017 - 00:00
The processes driving human abdominal aortic aneurysm (AAA) progression are not fully understood. Although antiinflammatory and proteolytic strategies effectively quench aneurysm progression in preclinical models, so far all clinical interventions failed. These observations hint at an incomplete understanding of the processes involved in AAA progression and rupture. Interestingly, strong clinical and molecular associations exist between popliteal artery aneurysms (PAAs) and AAAs; however, PAAs have an extremely low propensity to rupture.

On the influence of wall calcification and intraluminal thrombus on prediction of abdominal aortic aneurysm rupture

September 9, 2017 - 00:00
Parameters other than maximum diameter that predict rupture of abdominal aortic aneurysms (AAAs) may be helpful for risk-benefit analysis in individual patients. The aim of this study was to characterize the biomechanical-structural characteristics associated with AAA walls to better identify the related mechanistic variables required for an accurate prediction of rupture risk.

Long-term survival after acute kidney injury following ruptured abdominal aortic aneurysm repair

September 9, 2017 - 00:00
Acute kidney injury (AKI) is a major complication of ruptured abdominal aortic aneurysm (RAAA). Severe AKI is associated with high morbidity and mortality in the short term. The objective of this study was to determine the association between AKI after RAAA repair and long-term survival.

Review of aspirin and clopidogrel resistance in peripheral arterial disease

September 8, 2017 - 00:00
Aspirin resistance (AR) and clopidogrel resistance (CR) are terms used to describe a reduction in the medication's efficacy in inhibiting platelet aggregation despite regular dosing. This review gives context to the clinical role and implications of antiplatelet resistance in peripheral arterial disease (PAD).

Partial renal coverage in endovascular aneurysm repair causes unfavorable renal flow patterns in an infrarenal aneurysm model

September 8, 2017 - 00:00
To achieve an optimal sealing zone during endovascular aneurysm repair, the intended positioning of the proximal end of the endograft fabric should be as close as possible to the most caudal edge of the renal arteries. Some endografts exhibit a small offset between the radiopaque markers and the proximal fabric edge. Unintended partial renal artery coverage may thus occur. This study investigated the consequences of partial coverage on renal flow patterns and wall shear stress (WSS).

Impact of iliac artery anatomy on the outcome of fenestrated and branched endovascular aortic repair

September 6, 2017 - 00:00
Fenestrated and branched endovascular aneurysm repair (FB-EVAR) is a valid option to treat juxtarenal and pararenal abdominal aortic aneurysms and thoracoabdominal aortic aneurysms. Because successful deployment depends on complex maneuvers, hostile iliac artery anatomy (HIA) can prejudice the FB-EVAR outcome. The aim of the study was to evaluate the impact of HIA on FB-EVAR outcome.

Exercise training for intermittent claudication

September 2, 2017 - 00:00
The objective of this study was to provide an overview of evidence regarding exercise therapies for patients with lower extremity peripheral artery disease (PAD).

The association of venous thromboembolism chemoprophylaxis timing on venous thromboembolism after major vascular surgery

September 1, 2017 - 00:00
Venous thromboembolism (VTE) is reported to occur in up to 33% of patients undergoing major vascular surgery. Despite this high incidence, patients inconsistently receive timely VTE chemoprophylaxis. The true incidence of VTE among patients receiving delayed VTE chemoprophylaxis is unknown. We sought to identify the association of VTE chemoprophylaxis timing on VTE risk, postoperative transfusion rates, and 30-day mortality and morbidity in patients undergoing major open vascular surgery.

Association of arterial calcification with chronic limb ischemia in patients with peripheral artery disease

September 1, 2017 - 00:00
Arterial calcification is associated with an increased risk of limb events, including amputation. The association between calcification in lower extremity arteries and the severity of ischemia, however, has not been assessed. We thus sought to determine whether the extent of peripheral artery calcification (PAC) was correlated with Rutherford chronic ischemia categories and hypothesized that it could independently contribute to worsening limb status.
