    BackgroundAcute ischemic stroke caused by cervical internal carotid artery stenosis (ICS) with altered consciousness and progressive paralysis leads to a poor neurologic prognosis. When such a patient is brought to the hospital in the hyperacute phase, intravenous tissue plasminogen activator is first administered. However, when an indwelling carotid artery stent is required after administration, physicians often hesitate to use antithrombotic drugs. In this report, we propose performing staged angioplasty (SAP) for such cases.MethodsFour patients were retrospectively investigated. In all 4 patients, we immediately performed only percutaneous transluminal angioplasty (PTA) without antiplatelet drugs. If both cerebral perfusion on angiography and neurologic findings improved, no additional treatment was provided; otherwise, emergency carotid artery stenting (eCAS) was performed. In PTA-successful cases, eCAS or carotid endarterectomy (CEA) was performed with single or dual antiplatelet drugs at a later date.ResultsThe success rate of PTA was 50% (2 of 4), and the overall treatment success rate was 100% (4 of 4). Three patients had favorable outcomes (modified Rankin Scale [mRS] score 0-2), but unfortunately, 1 patient had severe disability (mRS score >3) on discharge. The PTA-successful patients had no perioperative complications. On the other hand, 1 of the 2 patients who underwent eCAS experienced embolic complications, including distal embolization.ConclusionsIn this investigation, both eCAS and SAP could be performed safety. However, performing SAP first without antiplatelet drugs to avoid hemorrhagic complications and cerebral hyperperfusion syndrome appears to have considerable validity.Copyright © 2019 Elsevier Inc.
