Authors' objectives:

This study aims to assess the current evidence on high-flow interposition extracranial to intracranial bypass.

Authors' recommendations: 1.1 Current evidence on the safety and efficacy of high-flow interposition extracranial to intracranial bypass does not appear adequate for this procedure to be used without special arrangements for consent and for audit or research. 1.2 This decision relates to the procedure when used for the treatment of diseases of the carotid artery, such as atherosclerosis. No judgement is made regarding its use as one part of a larger operation, such as bypassing an internal carotid artery that has been surgically occluded during resection of a tumour. 1.3 Clinicians wishing to undertake high-flow interposition extracranial to intracranial bypass should take the following actions: - Inform the clinical governance leads in their Trusts. - Ensure that patients understand the uncertainty about the procedures safety and efficacy and provide them with clear written information. Use of the Institute's Information for the Public is recommended. - Audit and review clinical outcomes of all patients having high-flow interposition extracranial to intracranial bypass. 1.4 Publication of safety and efficacy outcomes will be useful in reducing the current uncertainty. The Institute may review the procedure upon publication of further evidence.
