LTA-guided Antiplatelet Therapy in Interventional Treatment of Intracranial Aneurysms
Study Details
Study Description
Brief Summary
The use of intracranial stents broadens the indications for endovascular treatment of intracranial aneurysms and improves the cure rate, but it also increases the risk of postoperative ischemic complications in patients. The current standard dual antiplatelet regimen is considered to be an important method to reduce thrombotic events. However, some patients are resistant to antiplatelet drugs and have a high risk of thrombotic events. In actual clinical work, the standards for platelet function testing are not standardized, and the antiplatelet drug adjustment program also lacks norms and consensus. This study carried out a multi-center, prospective cluster randomized controlled study to explore whether the standardized antiplatelet adjustment program guided by LTA detection can reduce the incidence of ischemic events after stent implantation in patients with intracranial aneurysms. Further determine and correct the curative effect of the standardized use of antiplatelet drugs in the treatment of intracranial aneurysm stents, and finally formulate a set of standardized antiplatelet regimens for aneurysm stents.

No Intervention: control group Continue to use the center's original antiplatelet regimen |

Experimental: test group Use a standardized antiplatelet drug adjustment regimen based on LTA testing |
Drug: Adjustment of Antiplatelet Drugs
MPA-AA≥20%, give aspirin 200mg qd; MPA-ADP≥36.4%, give ticagrelor 60mg bid; MPA-ADP≥42.9%, give ticagrelor 60mg bid; MPA-ADP<20%, give Clopidogrel 37.5mg qd; The timing of drug adjustment should be at least 1 day before stent implantation, and the LTA results should be checked again after the drug adjustment, and the second antiplatelet drug adjustment should be performed for patients with drug overdose: *Aspirin overdose: Give 100mg, qd; *Overdose of ticagrelor: reduce to 30mg, bid;.
