Complex endovascular repair of type B aortic dissection and predicting left arm ischemia: a case report.

J Med Case Rep 2021 Apr 15;15(1):168. Epub 2021 Apr 15.

Division of Vascular Surgery and Endovascular Therapy, Rutgers Robert Wood Johnson School of Medicine, One Robert Wood Johnson Place, MEB 541, New Brunswick, NJ, 08901, USA.

Background: Thoracic endovascular aortic repair (TEVAR) is the gold standard for surgical management of descending thoracic aortic pathology. Depending on the anatomy, TEVAR often requires deployment across the origin of the left subclavian artery (LSA) to obtain a proximal seal, thus potentially compromising perfusion to the left upper extremity (LUE). However, in most patients this is generally well tolerated without revascularization due to collateralization from the left vertebral artery (LVA). Read More

Aspirin versus anticoagulation in cervical artery dissection (TREAT-CAD): an open-label, randomised, non-inferiority trial.

Lancet Neurol 2021 05 23;20(5):341-350. Epub 2021 Mar 23.

Department of Neurology and Stroke Centre, University Hospital Basel and University of Basel, Basel, Switzerland; Neurology and Neurorehabilitation, University Hospital for Geriatric Medicine Felix Platter, University of Basel, Basel, Switzerland.

Background: Cervical artery dissection is a major cause of stroke in young people (aged <50 years). Historically, clinicians have preferred using oral anticoagulation with vitamin K antagonists for patients with cervical artery dissection, although some current guidelines-based on available evidence from mostly observational studies-suggest using aspirin. If proven to be non-inferior to vitamin K antagonists, aspirin might be preferable, due to its ease of use and lower cost. Read More
