Duplex Imaging and Incidence of Carotid Radiation Injury After High-Dose Radiotherapy for Tumors of the Head and Neck

摘要: Radiation-induced carotid artery disease following high-dose (greater than 50-Gy) radiotherapy for head and neck cancer may become more common as improved treatment results in longer survival. Duplex ultrasound scans were obtained 91 consecutive patients to determine whether increased incidence severity of extracranial correlate with prior radiotherapy. Fifty-three who underwent an average 28 months previously 38 received no studied. Thirty percent the irradiated group had lesions arteries that either moderate or severe vs only 6% control patients. Five symptomatic; all undergone Long-term follow-up sequential duplex examinations is indicated receiving tumors, detect radiation-induced prevent late sequelae.
