…followed by disruption of the intima. Intramural haematoma differs from classic dissection because haemorrhage occurs within the media without imaging evidence of an intimal tear…

…pain or a rapid deterioration in general condition may be the only signs of infection. Corticosteroids and other immunosuppressive treatments can blunt the febrile response…

…ischaemia (ALI) is an abrupt reduction in arterial perfusion of an upper or lower limb that causes tissue metabolic requirements to exceed available blood flow…
