About this study
Official title: Multi-center, Single-blind, Prospective Cohort Study of Exploration of Anticoagulation Program in Cerebral Aneurysm and Arteriovenous Malformations With Hybrid Operation
In the stage of registration study, our purpose is to find out the safety range of activated coagulation time level in cerebral aneurysm and arteriovenous malformations with hybrid operation.
Read the detailed description
This study is divided into anticoagulation program in cerebral aneurysm with hybrid operation and anticoagulation program in cerebral arteriovenous malformations with hybrid operation two parts, and each part divide into two stage, on the stage of registration study. This study is a multi-center, single-blind, prospective cohort study. Record the patient's intraoperative activated coagulation time Changes in detail, to observe the effect of activated coagulation time maintenance level on hemorrhage event rate of Intraoperative and postoperative 48 hours, purpose to find out the safety range of activated coagulation time level in cerebral aneurysm and arteriovenous malformations with hybrid operation. On the stage of randomized controlled study. This study is a multicenter, single-blind, prospective, randomized controlled study. Patients is divided into intraoperative standard dose group of Heparin Sodium and low dose group of Heparin Sodium randomly. To observe the effect of different anticoagulation regimens on activated coagulation time safety coverage rate during surgery, and finally develop a scientific and effective intraoperative anticoagulant therapy program.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 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. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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
Ischemia event include Cerebral infarction and transient ischemic attack.
Measured: From the beginning of surgery to 48 hours after surgery
Intraoperative blood loss
All the blood lost during the surgery should be collected and measured.
Measured: During the surgery
