A Meta-Analysis of Total Arch Replacement With Frozen Elephant Trunk in Acute Type A Aortic Dissection
Conclusions: Total arch replacement with frozen elephant trunk provides a safe alternative to that with conventional elephant trunk in patients with acute type A aortic dissection, with acceptable early mortality and morbidity. The rates of mid- to long-term reintervention and false lumen non-thrombosis may be lower in patients undergoing the frozen than conventional elephant trunk procedure.

Body mass index strongly impacts the diagnosis and incidence of heparin-induced thrombocytopenia in the surgical intensive care unit
BACKGROUND: The obese state has been linked to several immune-mediated conditions. Our objective was to examine the association of body mass index (BMI) with the diagnosis of heparin-induced thrombocytopenia (HIT). METHODS: Prospectively collected data on patients in the surgical and cardiac intensive care unit suspected of having HIT between January 2007 and August 2014 were analyzed. Patients were categorized into five discrete BMI (kg/m2) groups and compared. Data collected included Warkentin 4-T scores, antiplatelet factor 4 (anti-PF4OD) values, serotonin release assay values, and thromboembolic diseases. HIT positivi...

Upper Extremity Ischemia as a “Warning Shot” of Cerebellar Infarction
A 44-year-old woman without cardiovascular risk factors complained of pain and coldness in the digits of her left hand. Radial and ulnar pulses were palpable, with equal brachial pressures on both sides. After a 2-hour stay in the outpatient department she developed acute headache, nausea, and vomiting. Computed tomographic scan with contrast medium revealed a floating thrombus in the left subclavian artery extending towards the origin of the vertebral artery (A). Brain magnetic resonance imaging demonstrated an infarction of the left cerebellum (B), whereupon the patient was immediately referred to the stroke unit.

Foot Embolization During Limb Salvage Procedures in Critical Limb Ischemia Patients Successfully Managed With Mechanical Thromboaspiration: A Technical Note
Conclusion: While further evaluation in a larger cohort of patients is needed, this initial experience using the Penumbra system in the peripheral vasculature suggests that this is a rapid, effective approach to address intraprocedural foot embolization and avoid possible grave clinical sequelae.

Long-term Outcome After EndoVAC Hybrid Repair of Infected Vascular Reconstructions.
CONCLUSION: The EndoVAC technique is an alternative, less invasive, option for treatment of infected vascular reconstructions in selected cases, when neither traditional radical surgery, nor conservative simple negative pressure wound therapy are considered feasible or safe. The exact indications for this alternative hybrid treatment need to be established. PMID: 26944600 [PubMed - as supplied by publisher]

A Unique Case of Aortic Thrombosis With Elevated Lipoprotein(a)
Aortic thrombosis is a rare condition that can be caused by atherosclerosis, aneurysms, thrombophilia, vasculitis, trauma, and malignancy. Symptoms vary based on thrombus size and site of embolization. It can lead to devastating complications including acute limb ischemia, myocardial infarction, stroke, and other target organ ischemia. Diagnosis is based on clinical presentation, imaging findings, and relevant laboratory work-up. Although not well defined, management for aortic thrombosis includes surgical intervention, such as thromboembolectomy, and conservative measures, such as anticoagulation. Here, we present a uniqu...

Pediatric National Surgical Quality Improvement Program: Useful for Quality Improvement in Craniosynostosis Surgery?
Abstract: The American College of Surgeons and the American Pediatric Surgical Association collaborate to provide pediatric hospitals with multispeciality surgical outcomes data through the Pediatric National Surgical Quality Improvement Program (NSQIP Peds). The authors used this national multicenter database to describe 30-day outcomes from craniosynostosis surgery and identify associations with perioperative events and blood transfusion. Data from NSQIP Peds were used to describe children undergoing craniosynostosis surgery. The authors examined statistical association of clinical risk factors with the defined end poin...

Contemporary Management of Type B Aortic Dissection in the Endovascular Era.
Authors: Bannazadeh M, Tadros RO, McKinsey J, Chander R, Marin ML, Faries PL Abstract Aortic dissection (AD) is one of the most common catastrophic pathologies affecting the aorta. Anatomic classification is based on the origin of entry tear and its extension. Type A dissections originate in the ascending aorta, whereas the entry tear in Type B dissections starts distal to the left subclavian artery. The patients with aortic dissection who manifest complications such as rupture, malperfusion, aneurysmal degeneration, and intractable pain are classified as complicated AD. Risk factors for developing aortic dissectio...

Acute Limb Ischemia and Outcomes With Vorapaxar in Patients With Peripheral Artery Disease: Results From the Trial to Assess the Effects of Vorapaxar in Preventing Heart Attack and Stroke in Patients With Atherosclerosis-Thrombolysis in Myocardial Infarction 50 (TRA2°P-TIMI 50)
Acute limb ischemia (ALI) occurs at a rate of 1.3% per year in patients with symptomatic peripheral arterial disease (PAD) without atrial fibrillation. Vorapaxar reduces ALI in patients with symptomatic PAD including PAD resulting from graft thrombosis and in-situ thrombosis.

The Influence of Collagen Impregnation of a Knitted Dacron Patch Routinely Used in Carotid Endarterectomy
In selected populations, carotid endarterectomy (CEA) reduces long-term stroke risk. Studies have shown increased risk of restenosis with use of a collagen-impregnated Dacron patch compared to a PTFE patch. There is concern that collagen-impregnation may initiate thrombosis or increase restenosis due to platelet activation. We performed a retrospective analysis of our CEA experience with routine patching using knitted Dacron patches with (Hemashield) and without (Sauvage) collagen-impregnation.

Late Retrograde Migration of a Left Subclavian Artery Chimney Stent-Graft Into the Innominate Artery
Conclusion: Migration of the proximal end of an overly long chimney graft that moved freely in the aortic arch exposed the patient to a high risk of stroke and death. Because of the high-risk situation, open repair under circulatory arrest was elected to remove the proximal end of the chimney graft, with no major complications.

Antiphospholipid antibodies and lower extremity peripheral arterial disease - a systematic review and meta-analysis.
CONCLUSIONS: Our systematic review and meta-analysis suggests that the prevalence of persistently elevated levels of antiphospholipid antibodies is increased in patients with lower extremity peripheral diseases when compared to healthy controls, especially in those with critical limb ischaemia.

In selected populations, carotid endarterectomy (CEA) reduces long-term stroke risk. Studies have shown increased risk of restenosis with use of a collagen-impregnated Dacron patch compared to a PTFE patch. There is concern that collagen-impregnation may initiate thrombosis or promote restenosis due to platelet activation. We performed a retrospective analysis of our CEA experience with routine patching using knitted Dacron patches with (Hemashield) and without (Sauvage) collagen-impregnation.
