Comparison Study Between Suction Aspiration and Combination Technique in Acute Cerebral Infarction

Официальное название

Comparison of Clinical and Radiological Outcomes Between Suction Aspiration Method and Combination Method of Intra-arterial Therapy (IAT) in Large Artery Occlusion: Randomized Open-labelled Prospective Multicenter Trials

Обзор

Mechanical thrombectomy of acute ischemic stroke caused by major vessel occlusion of the anterior circulation has become an accepted procedure in the last decade. Recent IAT modalities have been classified as suction aspiration,stent retrieval and combination modality. The suction aspiration technique is limited by the possibility of breaking the entire thrombus during the IAT. In addition, the stent retrieval technique is also limited because of thrombus migration during stent removal from an acute-angled artery as in the case of a carotid siphon. According to recent development of suction catheter, investigators expected that suction aspiration will prevent breaking the entire thrombus during the IAT. Investigators will evaluate the radiological and clinical outcome of suction aspiration technique in comparison with combination technique in the large artery occlusion feasible to both suction aspiration and combination technique prospectively in a randomized trial.

Alphabetic number of each hospital is an each hospital code.

If the patient with acute cerebral infarction will be feasible to suction aspiration and combination technique, the investigator who can enroll the patient should check the order of random table in open chatting board and perform the ordered method after completion of consent for the COMPETE trials.

Each investigator in the hospitals participated in COMPETE trials will write the competetrials spread sheet on google web.

The image files of thrombectomy including pre-thrombectomy and post-thrombectomy will be converted to zip file and send to the independent neurointerventional radiologist on e-mail about 2 \~ 4 times a year. the independent examiner will re-send to the investigator after completion of modified TICI grade in the image files of thrombectomy.

This study should not enroll atherosclerotic tandem occlusion. Other etiologies such as cancer related stroke or dissection should not be enrolled in this study.

Cases of Atherosclerotic steno-occlusion will be included in this study. Rescue treatment such as primary stenting or conventional modality will be performed according to the favored modality of each investigator.
