The authors investigated the impact of early extubation and ventilation duration in a cohort of 103 patients that underwent thrombectomy under general anesthesia. Prolonged ventilation was associated with pneumonia during hospitalization and unfavorable functional outcome (mRS greater than or equal to 3) and death at follow-up. According to ROC analysis, a cutoff after 24 hours predicted unfavorable functional outcome with a sensitivity and specificity of 60% and 78%, respectively. The authors conclude that short ventilation times are associated with a lower pneumonia rate and more favorable clinical outcome.

Twenty-one patients with previously stented recurrent aneurysms who later underwent Pipeline Embolization Device placement (group 1) were retrospectively identified and compared with 63 patients who had treatment with the Pipeline with no prior stent placement (group 2). Pipeline treatment resulted in complete aneurysm occlusion in 55.6% of patients in group 1 versus 80.4% of patients in group 2. The retreatment rate in group 1 was 11.1% versus 7.1% in group 2. The authors conclude that the Pipeline is less effective in the management of previously stented aneurysms than when used in nonstented aneurysms.
