ABSTRACT
Stroke represents a major complication in Takayasu arteritis (TA). We aimed to determine clinical characteristics and neurological outcomes in TA patients with stroke compared to those without. We retrospectively analyzed 35 patients (27F/8 M) with documented stroke to 50 consecutive patients (47F/3 M) without stroke followed by the Istanbul University-Cerrahpasa Medical Faculty. Demographic data, clinical manifestations, arterial involvement patterns, treatments, and neurological outcomes were evaluated. Disability was assessed using the Expanded Disability Status Scale (EDSS), Barthel Index, and Modified Rankin Scale. Mean age at diagnosis among patients with stroke and non-stroke was similar (38.5 ± 10.7 vs. 35.6 ± 11.6 years). The mean age at stroke was 43.1 ± 10.3 years. Patients with stroke were more likely to be male (22.9% vs. 6.0%, p = 0.023). Strokes were predominantly ischemic (91.4%), affecting anterior circulation (82.8%) with left hemisphere predominance (72.4%). Internal carotid artery (ICA) involvement was significantly associated with stroke (right ICA: 51.4% vs 18.0%, p = 0.001; left ICA: 37.1% vs 18.0%, p = 0.047), while abdominal aorta involvement seemed to be protective (20.0% vs 42.0%, p = 0.028). Male gender (OR = 5.70, p = 0.038) and any ICA involvement (OR = 5.98, p = 0.004) were identified as independent predictors of stroke. Importantly, 40% experienced stroke as the initial TA manifestation. Among those developing stroke after TA diagnosis, 85.7% were already receiving immunosuppression and 47.6% antiplatelet therapy. Stroke patients demonstrated significant disability (mean EDSS: 3.63 ± 3.36 vs 0.02 ± 0.14, p < 0.001) and 11.4% mortality, median 5 years after stroke. Male patients and those with ICA involvement face the highest risk for stroke in TA. Long-term consequences are devastating with increased mortality, severe disability and high recurrence rates. The failure of immunosuppressive therapy to prevent stroke in the majority of treated patients, combined with substantial perioperative mortality, stress the inadequacy of current management strategies.
