ABSTRACT
Takayasu arteritis is a rare inflammatory disease that primarily affects medium- and large-sized arteries, particularly the aorta and its branches. The Hata classification defines six angiographic types based on the involved aortic segments. Clinical symptoms May vary depending on the distribution of arterial involvement. This systematic review and meta-analysis aimed to estimate the pooled prevalence of each angiographic type and evaluate their associations with clinical Manifestations.A systematic search of electronic databases was conducted to identify studies reporting angiographic classifications and clinical symptoms in patients with Takayasu arteritis. Pooled prevalence estimates were calculated using R software, including subgroup analyses by geographic area and imaging modality. Meta-regression was used to assess associations between angiographic types and specific clinical features.Type V was the most common angiographic subtype, with a pooled prevalence of 43.49%, while type III was the least common, 5.32%. Subgroup analyses showed statistically significant differences only for type IIb, based on modality types. Meta-regression revealed significant correlations between angiographic types and clinical symptoms, with Type V exhibiting the greatest severity, and types IIb and III the lowest.This meta-analysis highlights the varying distribution of angiographic types of Takayasu arteritis and their significant associations with clinical symptoms, which may guide prognostic and management strategies.
