Outcome Measures

Primary Outcomes (1)

  • Changes in hemorrhage event rate from the beginning of surgery to 48 hours after surgery

    Hemorrhage event include intracranial hemorrhage caused by non-surgical reasons, as well as other organs or parts of the massive bleeding or small bleeding, Including subperitoneal hemorrhage, intraocular hemorrhage, gross hematuria, epistaxis time prolonged or repeated, gastrointestinal bleeding, hemoptysis, subconjunctival hemorrhage, hematoma greater than 5cm, bleeding difficult to control the and so on.

    From the beginning of surgery to 48 hours after surgery

Secondary Outcomes (2)

  • Changes in ischemia event rate from the beginning of surgery to 48 hours after surgery

    From the beginning of surgery to 48 hours after surgery

  • Intraoperative blood loss

    During the surgery

Study Arms (2)

aneurysm

For cerebral aneurysm with hybrid operation, anticoagulation program is decided by different surgeons based on their experience and record the patient's intraoperative activated coagulation time changes in detail.

arteriovenous malformations

For arteriovenous malformations with hybrid operation, anticoagulation program is decided by different surgeons based on their experience and record the patient's intraoperative activated coagulation time changes in detail.
