2018
Abstract Purpose To study the results and complications of endovascular treatment (EVT) in acute ischemic stroke patients admitted to intensive care unit (ICU). To analyse the possible factors related to mortality and level of disability at ICU discharge and one year after stroke. Design Observational prospective study. Setting Mixed ICU. Third level hospital. Patients Sixty adult patients. Consecutive sample. Interventions None. Variables of interest Epidemiological data, time from symptom onset to EVT, angiographic result, length of stay, days on mechanical ventilation, neurological complications, National Institutes of Health Stroke Scale (NIHSS) at ICU admission and discharge, modified Rankin scale score (mRS) at one year. Results Mean age 68.90 ± 8.84 years. Median time from symptom onset to EVT: 180 min. Median NIHSS at admission: 17.5; at discharge: 3. Distal flow was achieved in 90% of cases. Median ICU stay: 3 days. Mechanical ventilation: 81.7%. Functional independence (mRS ≤ 2) 50% at one year. Deaths: 22 (36,6%) of which 8 (13.3%) died during UCI stay and the rest during the first year. Conclusions The factors relating to a worse functional outcome were symptomatic hemorrhage transformation, lack of recanalization and complications during EVT. The factors relating to mortality were symptomatic hemorrhage and hydrocephalus. Distal flow was achieve in most cases with a low complication rate. Half of the patients presented functional independence one year after the stroke.
