Classic pathologic findings are thrombosis and recanalization in medium-small vessels and meningeal vessels, both in patients with and without antiphospholipid antibodies [4].
A number of studies have characterised medium and small vessel lesions in SHRsp, but little attention has been paid to the changes in the wall structure of large arteries induced by exposure to a salt-enriched diet.
In general, symptomatic cardiac involvement is associated with poor prognosis in patients with medium or small vessel vasculitis and justifies a strong and immediate immunosuppressive treatment.
