Long-Term Follow-Up in Patients with Large-Vessel Vasculitis Applying Extracranial and Transcranial Duplex Sonography

Abstract: Background: Although large-vessel vasculitis (LVV) can affect both the anterior and posterior intracranial circulation, routine neurosonographic follow-up, including transcranial duplex sonography, has not been established. We aimed to characterize patients with giant cell arteritis (GCA) and Takayasu arteritis (TAK) regarding the detection of progressive or new-onset inflammatory vessel changes by using neurosonography, and to assess the impact on medical or interventional treatment strategies. Methods: We retrospectively identified all patients with LVV treated at our neurological department between January 2015 and October 2025 with at least one neurosonographic follow-up examination. Baseline and follow-up sonographic data, clinical characteristics, medical therapy, and interventional treatments were analyzed. Results: In total, 21 LVV patients (GCA, n = 16; TAK, n = 5) underwent sonographic follow-up (GCA: median 28 (2–106) months, 4.5 (2–33) sonographic assessments; TAK: 75 (33–255) months, 14 (4–60) sonographic assessments). Isolated or combined, progressive or new-onset intra- and extracranial arterial disease was detected in seven of the 16 GCA patients (43.8%), of whom three (18.8%) presented with ischemic stroke. Medical treatment was adapted in four progressive cases. In two patients, additional interventional treatment was performed. Among TAK, two of five (40%) patients showed progressive sonographic changes, with one patient experiencing an ischemic stroke requiring endovascular treatment for progressive common carotid artery stenosis and one patient showing asymptomatic intracranial ICA involvement. Conclusions: Progressive and symptomatic involvement of intracranial carotid and vertebral arteries is a frequent finding in patients with LVV. These changes can be effectively detected through comprehensive neurosonographic follow-up, including transcranial ultrasound assessment.
