About this study
Official title: Stereotactic Infarct Tissue Aspiration (SITA) for Malignant Infarction of Middle Cerebral Artery
Malignant middle cerebral artery infarction(MMCI) has a high rate of disability and mortality. At present, there is no effective treatment except for craniotomy decompression, but the controversy of the craniotomy decompression still exists. The project is a prospective, randomized, single center, open label, clinical controlled trail. The eligible patients for enrollment are as follows: (1) malignant cerebral artery infarction within 48h onset; (2) craniotomy decompression can not be performed due to the contraindications, or refused by the patient or relatives. The patients are randomly assigned into 2 groups: (1)Medical therapy group: receiving osmotic therapy with mannitol and glycerol fructose，anti-platelet treatment, statins, and other symptomatic treatments such as controlling blood pressure, blood sugar, and infection, tracheal intubation or incision, etc; (2) Stereotactic infarct tissue aspiration (SITA) group: on the basis of medical treatment, receiving minimally invasive aspiration of infarct tissue 24-48 hours after stroke attacked. This study is aimed at comparing the efficacy and safety of of SITA in patients with MMCI.
Read the detailed description
Malignant middle cerebral artery infarction (MMCI) has a fatality rate of up to 80%, due to massive brain edema, increased intracranial pressure, and cerebral herniation. The herniation-induced death usually occured during the first week, despite aggressive osmotherapy with mannitol or hypertonic saline, sedation, and eventually hyperventilation, buffers, or hypothermia. A growing evidence show that decompression craniectomy (DC) can produce a significant reduction in mortality rate and an improvement in neurological outcome, but the controversy of the DC still exists. There is an urgent need to find a more effective treatment method. Given that brain tissue necrosis-induced edema and cerebral herniation is the key reason of fatality and disability of MMCI patients, the investigators argue that the reduction of cerebral tissue volume by stereotactic infarct tissue aspiration (SITA) is likely to reach the decompression effect similar to the DC. Recently, the investigators performed SITA in 2 MMCI patients who were qualified for decompressive craniectomy, but refused by patient relatives, and their neurological function significantly improved.
The project is a prospective, randomized, single center, open label, clinical controlled trail. The eligible patients for enrollment are as follows: (1)ages from 40 to 90 years old; (2) malignant cerebral artery infarction within 48h onset; (3) craniotomy decompression can not be performed due to the contraindications, or refused by the patient or relatives. The patients are randomly assigned into 2 groups: (1) Medical therapy group: receiving osmotic therapy with mannitol and glycerol fructose，anti-platelet treatment, statins, and other symptomatic treatments such as controlling blood pressure, blood sugar, and infection, and tracheal intubation or incision, etc; (2) SITA group: receiving minimally invasive aspiration of infarct tissue 24-48 hours after stroke attacked on the basis of medical treatment. This study is aimed at comparing the efficacy and safety of of SITA in patients with MMCI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Stereotactic infarct tissue aspirationProcedure or surgery
The patient posed supine position to expose local skin and puncture point was located at 6.5 cm behind the hairline of the lesion side, and 5.0 cm lateral of midline. After routine skin preparation and disinfection, 5% lidocaine 2-5 ml was injected for local anesthesia. The skin was cut to expose periosteum by a scalpel. After skull was vertically drilled through with a 6mm diameter hole, a sterile tube with a needle in tube was put about 8 cm into centrum semiovale. The needle was put out and about 50ml necrosis brain tissue was aspirated by a 20 ml syringe. The tube was fixed into the skin about 2 cm after subcutaneous tunnel, and connected to the drainage bag. Surgical area was sterilized and wrapped by sterile gauze bandage.

Questions about this trial
What is this clinical trial studying?
A study testing Stereotactic infarct tissue aspiration and Medical therapy in people with Middle Cerebral Artery Infarction, run by General Hospital of Shenyang Military Region at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 14 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Modified Rankin Scale(mRS) 0-3 vs mRS 4-6 (time frame: 90±7days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02609256, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2018.
