Brief Summary

Aneurysmal subarachnoid hemorrhage (SAH) is a frequent worldwide cause for stroke with a mortality of around 30%. Worldwide, almost 500 000 patients have aneurysmal SAH annually.An incidence of 2-16 cases of spontaneous SAH per 100 000 person-years was reported in a recent meta-analysis . Surgical treatment of aneurysms is essential in the acute phase of aSAH patients, either by surgical clipping or by endovascular embolization. Although there are many factors that influence the prognosis of patients with aSAH, cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) are the main factors contributing to the high mortality rate (30-40% within 30 days) and poor long-term functional prognosis of patients after aSAH. Cerebral vasospasm (CVS) is defined as focal or diffuse temporary narrowing of vessel diameter due to contraction of smooth muscle in the arterial wall, which can be detected by digital subtraction angiography (DSA), transcranial ultrasound Doppler (TCD), magnetic resonance (MR), and CT angiography (CTA) or visualised during intraoperative.The prevalence of CVS after aSAH is 67% , with symptomatic patients (symptomatic vasospasm) in 30-40% of them and leading to ischaemic events in 10-45% of patients. It usually begins 3-4 days after bleeding, peaks at 7-10 days and finally resolves at around 14-21 days. There is no effective treatment to prevent cerebral vasospasm events.Shuxuening Injection is a sterilized aqueous solution made by extraction of Ginkgo biloba. The study aims to clarify the clinical study of the efficacy and safety of Shuxuening Injection (10ml/branch) for the prophylactic of cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants with cerebral vasospasm(CVS)

    The prevalence of CVS after aSAH is 67% , with symptomatic patients (symptomatic vasospasm) in 30-40% of them and leading to ischemic events in 10-45% of patients. It usually begins 3-4 days after rupture bleeding, peaks at 7-10 days and finally resolves at around 14-21 days.

    Cerebral vasospasm events within 14 days

Secondary Outcomes (1)

  • Rate of Delayed Cerebral Ischemic(DCI)

    Delayed cerebral ischemic events within 14 days

Other Outcomes (1)

  • modified Rankin scale(mRS)

    modified Rankin scale(mRS) within 14 days and 90 days

Masking Details
To ensure blinding, personnel involved in randomisation coding or with potential access to the blind base, doctors or nurses administering the medication, should not be involved in activities such as selection of subjects, evaluation of efficacy, and assessment of safety, so as not to introduce bias. In addition, to ensure blinding, the packaging and batch numbers of the drugs in both groups will be identical, and the packaging batch numbers will be uniformly labelled. Each box will be labelled with a unique drug ID number. This number will be used to designate the treatment received by the patient, but will not indicate treatment assignment to the investigator or the patient.
