Use of heparin in neurointervention: A review of the literature

Abstract

Background: The use of heparin is routine in endovascular procedures as a strategy in many centers that perform neurointerventional procedures to prevent occlusion of the catheters, but the use of this drug carries risks such as heparin-induced thrombocytopenia.
Objective: The purpose of this paper is to present a review of the literature.
Material and methods: We conducted an extensive search and review of published papers about heparin and neurointerventional procedures.
Results: The evidence in the literature is weak in relation to the use of heparin and the reduction of embolic effects associated with their use in endovascular procedures.
Conclusion: The evidence on the use of heparin for the prevention of thromboembolic events in endovascular procedures are of low quality. There is insufficient evidence to conclude a potential benefit of heparin is useful in neurointerventional procedures. Prospective studies are needed to determine the effectiveness of heparin and avoid exposing patients to potential risks.
