  • Ages 19-75
  • All Genders
  • Accepts Healthy Volunteers

Study Summary

Low clopidogrel response has been reported in about 5-44% of the total population, which is associated with an increase in thromboembolism.

Recently prasugrel drug widely accepted as a good option for these patients. The purpose of this study is to compare the safety and usefulness of prasugrel versus clopidogrel in patients who are scheduled to undergo stent or diverter treatment for non-ruptured cerebral aneurysms.

Eligibility Criteria

Inclusion

Inclusion Criteria:

Exclusion

Exclusion Criteria:

  • ∙ History of acute ischemic stroke or transient ischemic attack
  • Any intracranial hemorrhage except subarachnoid hemorrhage due to aneurysmrupture within the last 3 months

Study Description

Unruptured intracranial aneurysm (UIA) is a relatively common disease with a prevalence of about 1% of the total population. Widely accepted techniques of neuro-interventional therapy are coil embolization with or without stent deployment and flow diverter insertion. However, these two techniques inevitably had the risk of thromboembolism. For prevention and decrease, dual antiplatelet therapy is commonly used in the clinical field. However, clopidogrel does not produce normal metabolites due to various internal and external factors in the metabolic process in the liver and eventually fails to perform its original role of platelet activity suppression in many situations, called "clopidogrel hyporesponsive". Low clopidogrel response has been reported in about 5-44% of the total population, which is associated with an increase in thromboembolism.

Recently prasugrel drug widely accepted as a good option for these patients. The purpose of this study is to compare the safety and usefulness of prasugrel versus clopidogrel in patients who are scheduled to undergo stent or diverter treatment for non-ruptured cerebral aneurysms.
