Impact of cranial and axillary/subclavian artery involvement by color duplex sonography on response to treatment in giant cell arteritis.

Objective: Color duplex sonography (CDS) today is broadly used in the diagnostic workup of patients with suspected cranial or extracranial giant cell arteritis (GCA). This study aimed to determine the prognostic impact of the disease pattern assessed by CDS on the treatment response in GCA.

Methods: This was a retrospective, longitudinal follow-up study of 43 patients who were diagnosed with GCA at our institution between 2002 and 2010.

Outcome of giant cell arteritis of the arm arteries managed with medical treatment alone: cross-sectional follow-up study.

Objective: To assess the long-term outcome of GCA of the arm arteries under medical treatment alone.

Methods: Retrospective cross-sectional study of 34 patients with a diagnosis of GCA involving the arm arteries (i.e.
