Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Elevated low-density lipoprotein cholesterol (LDLC) levels increase the risk of vascular events. Lipid-lowing treatment with β-Hydroxy β-methylglutaryl-CoA reductase inhibitors (such as statins) is a cornerstone in avoiding such events. Several studies indicate that the advantages of statins could surpass their traditional role in lowering cholesterol levels, encompassing a range of additional benefits known as pleiotropic effects. Those multiple effects include anti-inflammatory function, vasodilation, anticoagulation, platelet inhibition, and antioxidants. Although the clinical benefit of statin pretreatment has been clarified in carotid artery stenting, percutaneous coronary intervention, and abdominal aortic aneurysm repair, its effect on endovascular treatment of UIAs remains unclear.
Due to the pleiotropic benefits beyond lipid lowering, the effect of statin pretreatment may theoretically contribute to the reduction of cerebrovascular events after FD implantation. Nevertheless, there is currently a lack of high-quality clinical evidence supporting this hypothesis. Thus, we designed the atorvastatin pretreatment in cerebrovascular events (APICES) randomized controlled trial (RCT) to explore whether statin pretreatment is superior to placebo in patients undergoing FD treatment for UIAs.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control group
placebo (composed mainly of starch, Frontage Pharma, Jiangsu, China) 20mg orally once daily for 180 days
Atorvastatin 20mg
Eligible subjects screened will enter the pretreatment period (at least 24 hours) and be randomly assigned to the trial group (oral atorvastatin) or the control group (placebo) to start receiving the trial drug (20mg, qd). Additionally, the patient was started on basic dual anti-platelet (aspirin 75mg qd + clopidogrel 75mg qd/ticagrelor 45mg bid).
Experimental group
atorvastatin (Pfizer, New York, USA) 20mg orally once daily for 180 days
Atorvastatin 20mg
Eligible subjects screened will enter the pretreatment period (at least 24 hours) and be randomly assigned to the trial group (oral atorvastatin) or the control group (placebo) to start receiving the trial drug (20mg, qd). Additionally, the patient was started on basic dual anti-platelet (aspirin 75mg qd + clopidogrel 75mg qd/ticagrelor 45mg bid).

10. Patient was determined that intravenous general anesthesia or general anesthesia with tracheal intubation could not be tolerated.
11. Unwilling to be followed up or likely to have poor treatment compliance at initial screening;
12. Life expectancy less than 3 years;
13. Severe neurological deficit that renders the patient unable to live independently (modified Rankin score ≥4);
14. Enrollment in another trial.
Withdrawal criteria
In this trial, participants who have provided written informed consent but are unable to complete the entire study for any reason will be withdrawn. These circumstances include the following:
1. The participants voluntarily quit the trial for various reasons;
2. Occurrence of serious adverse events (SAEs). The study may be terminated by the participants, principal investigators, ethics committee, sponsor, or regulatory authorities based on ethical considerations;
3. Early termination of the process based on the investigator's judgment in order to prevent development of severe complications;
4. Significant deviation in implementation, or the subject failed to comply with the scheduled protocol;
5. Miss the follow-up due to changes in working/living places, or fortuitous accident (traffic accident, bone fracture, accidental death, ect.). Thus, close follow-up should be conducted to determine their relationship with the usage of FD and experimental drug;
6. Flawed or absence of informed consents.
