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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a prospective one arm trial designed to assess the safety and efficacy of MMA embolization with liquid embolic agents (onyx/squid/Phil) as the main treatment of CSDH.

The subjects are enrolled in the study according to inclusion and exclusion criteria. Imaging and clinical presentations of patients are recorded. Within 48 hours of embolization, patients are assessed with clinical examination and with a brain CT scan to evaluate in any change in their symptoms and CSDH volume. 2-4 weeks after embolization, patients are evaluated in clinic for any change in their symptoms and signs. 60 days after embolization patients are examined clinically and are assessed for SDH volume change in CT scan and MRI.

If there is any significant increase in CSDH volume or any deterioration of patient, evacuation of hematoma is considered.

MMA embolization is performed under general anesthesia using biplane or monoplane angiography. Femoral or radial accesses are used. Guiding catheter is advanced into external carotid artery in corresponding side. The corresponding MMA is catheterized distally by micro-catheter and is embolized by liquid embolic agents. Patients are discharge next day if they are stable.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.
