Abstract
We examined treatment outcomes and problems of thrombectomy at our hospital, the only center that performs them in our medical area. We examined the characteristics of percutaneous cerebrovascular thrombectomy in 56 patients who underwent the procedure for acute cerebral arterial obstruction between January 2015 and May 2017. Patient mean age was 69.0 ± 14.0 years, with a female/male ratio of 20:36. Of the 56 patients, 27 were referred from other hospitals and 29 were direct admissions. We examined the background, vessel subjected to treatment, and treatment outcomes of all patients. We found that the median National Institute of Health Stroke Scale (NIHSS) score was 15.5 (interquartile range: 11‒19.25), and the time from onset to recanalization was 263 min. Successful recanalization for thrombolysis in cerebral infarction (TICI) grade equal to or more than 2b was achieved in 44 patients (78.6%). Symptomatic intracranial hemorrhage was observed in three patients (5.4%). Favorable outcome at 90 days (modified Rankin Scale: mRS ≤ 2) was noted in 28 patients (50.0%). Our univariate analyses revealed that the factors associated with favorable therapeutic outcomes included age, NIHSS score, time from onset to recanalization, and successful recanalization. Our examination showed that we need to refer from other hospitals more quickly, shorten the time from onset to recanalization, and increase successful recanalization.
