Abstract

The surgical treatment of radio-induced carotid stenosis (RICS) is challenging and burdened with high risk of complications. Carotid stenting (CAS) may be a valid alternative, but better approach is still not defined. Two approaches have been assessed in this an observational monocentric study, focusing on perioperative and follow-up complications. From 2005 to 2013, data on patients treated for extracranial carotid stenosis with previous radiotherapy (RT) for head or neck tumor were prospectively collected according to the procedure performed (open repair [OR], endovascular stenting [CAS]). Patient demographics, clinical risk factors, organ of cancer origin, elapsed time from RT, duplex ultrasound (DUS) and clinical presentation of carotid stenosis were preoperatively gathered. Primary outcomes were technical success, 30-day mortality, transient ischemic attack (TIA)/stroke and myocardial infarction (MI). In OR group, laterocervical hematoma and cranial nerve injury were evaluated and, in CAS group, arterial access site complications were considered as well. Secondary outcomes were the mortality, TIA/stroke, restenosis and reintervention during follow-up. Fifteen RICS were treated in 12 patients (M/F=9/3; median age: 71 years,...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
