PLAT and cerebral amyloid angiopathy: A total of 175 patients were identified with a supratentorial ICH volume of >30 mL who had been treated with bedside catheter aspiration; 65 of these were excluded from analysis due to the following specific causes of ICH: cerebral amyloid angiopathy (n = 21), therapeutic anticoagulation (vitamin-K antagonists, dabigatran, rivaroxaban, apixaban, edoxaban, heparin; n = 32), and systemic thrombolysis with recombinant tissue plasminogen activator for ischaemic stroke (n = 12).
