October 10, 2017 updated by: Dr. Yong Cao, Beijing Tiantan Hospital

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.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 70 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in hemorrhage event rate from the beginning of surgery to 48 hours after surgery
Time Frame: 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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in ischemia event rate from the beginning of surgery to 48 hours after surgery
Time Frame: From the beginning of surgery to 48 hours after surgery
Ischemia event include Cerebral infarction and transient ischemic attack.
From the beginning of surgery to 48 hours after surgery
Intraoperative blood loss
Time Frame: During the surgery
All the blood lost during the surgery should be collected and measured.
During the surgery

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2016

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
