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

To evaluate the effect of different surgical approaches on the prognosis of patients with hypertensive intracerebral hemorrhage, hypertensive patients who met the diagnostic criteria of American guidelines for the treatment of adult spontaneous intracerebral hemorrhage (2015) were selected. The time from onset to admission was less than 8 hours. Blood routine examination, liver and kidney function, coagulation system, infectious diseases and other examinations were performed before operation, with emergency surgical indications, They were divided into two groups: transfrontal keyhole approach and transoccipital keyhole approach. Emergency endoscopic hematoma removal was performed. The patients were systematically evaluated and followed up at 1 week, 1 month, 3 months, 6 months and 12 months after operation to observe the improvement of consciousness, GCS score, postoperative rebleeding (appearance, bleeding volume, location, broken into ventricle, etc.), The prognosis was evaluated by ADL score, GCS score, gos score, modified Rankin scale, Mrs scale and ICH Score (GCS, hematoma volume, intraventricular hemorrhage, infratentorial source, patient age, etc.).

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.

Ages Eligible for Study

15 years to 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Intervention / Treatment

Active Comparator: Trans-frontal keyhole approach
After general anesthesia, the patient was placed in supine position with head frame fixed. A straight or arc incision was made in the hairline of the affected side. The incision was 3cm beside the midline. The length of the incision was about 4cm and the diameter of the bone window was about 2.5cm. According to the preoperative thin-layer CT scan, the dura mater and part of the cerebral cortex were cut, and the endoport and other hard channels were inserted. The incision reached 2 / 3 of the length of the hematoma along the direction parallel to the long axis of the hematoma, During the operation, mini aneurysms were clipped to close the responsible vessels, and hemostatic gauze was applied on the surface of the hematoma cavity. Silica gel external drainage tube was placed in the hematoma cavity. The external drainage tube led out the skin through the subcutaneous tunnel, and the dura was sutured.

Active Comparator: Trans-occipital keyhole approach
After general anesthesia, the patient was placed in prone position with head frame fixed. According to the preoperative thin-layer CT scan, the long axis of hematoma was perpendicular to the ground, and the occipital puncture point was found along the extension line of the long axis of hematoma. Taking the puncture point as the center, a straight or arc incision parallel to the sagittal sinus was taken. The length of the incision was about 4cm, and the diameter of the bone window was about 2.5cm, Endoport and other hard channels were inserted to reach 2 / 3 of the long diameter of the hematoma along the direction parallel to the long axis of the hematoma. Under the neuroendoscope, the hematoma was aspirated or resected in blocks. During the operation, mini aneurysm clamp was used to clamp the responsible vessels, and hemostatic gauze was applied on the surface of the hematoma cavity. Silica gel external drainage tube was placed in the hematoma cavity.
