ABSTRACT

BACKGROUND: The DAWN and DEFUSE-3 trials showed the benefit of endovascular treatment (EVT) in acute ischemic stroke patients presenting beyond 6 hours from last known well (LKW) and selected by perfusion imaging criteria. The ESCAPE NA1-trial selected patients based on non-contrast CT (NCCT) Alberta Stroke Program Early CT Score (ASPECTS) and multiphase CT angiography (CTA) collateral status. This study compares baseline characteristics, workflow, and outcomes in the EVT arms of DAWN and DEFUSE-3 with late-window patients from the EVT-only arm of ESCAPE-NA1. METHODS: Aggregate data on baseline characteristics, workflow, reperfusion quality, final infarct volume, and clinical outcomes (modified Rankin Score [mRS] at 90 days) in subjects enrolled in the DAWN and DEFUSE-3 EVT arms were compared with similar data from the ESCAPE-NA1 control arm (EVT-only arm) presenting beyond 6 hours from LKW using descriptive statistics. RESULTS: Baseline characteristics among late-window patients in the ESCAPE NA1 trial were similar to those in the DAWN and DEFUSE-3 EVT arms. Median time from LKW-to-puncture in subjects enrolled in the ESCAPE NA1 trial was 9 hrs (IQR: 7.5-11 hours) when compared with DAWN (n=107; 12.8 hours, IQR: 10.6-16.7 hours) and DEFUSE-3 (n=92; 11.5 hours, IQR: 9.2-12.8 hours). Median post-treatment infarct-volume was largest in the ESCAPE NA1-patients (47 mL [IQR: 19-146] vs median 8 mL [IQR: 0-48] in the DAWN group and 35 mL [IQR: 18-82] in DEFUSE-3), while % mRS 0-2 at 90 days were similar across the three trials (ESCAPE NA1: 50/111 [45%], DAWN: 52/107 [49%], DEFUSE-3: 41/92 [45%]). CONCLUSION: Patients enrolled beyond 6 hours from LKW in the ESCAPE-NA1 trial based on NCCT-ASPECTS and mCTA had similar clinical outcomes when compared with patients selected by perfusion imaging in the DAWN and DEFUSE-3 trials.

ABSTRACT

OBJECTIVE: To determine the time to complications during and after elective endovascular intracranial aneurysm coiling. METHODS: A retrospective chart review of patients undergoing elective endovascular aneurysm coiling between March 2006 and October 2013 in one large Eastern Canadian Neurointerventional Service was performed. Data regarding the incidence, time and type of complication related to the endovascular coiling procedure and clinical outcome at last follow-up were collected. Patient, aneurysm and operation factors were analyzed to determine any factors associated with complication occurrence. RESULTS: Of the 150 patient procedures analyzed, 16% experienced a coiling-related complication, although none resulted in death. 6.7% of patients experienced an intraoperative complication, of which thromboembolism was the most common type. The majority of the complications were detected in the first 6 hours after reversal of anesthesia, and a small proportion the next morning prior to discharge. Only 3.3% of patients had persistent neurological deficit after the procedure on last follow-up. Duration of the operation demonstrated a strong association with the occurrence of procedure-related complications. CONCLUSION: This study demonstrates that coiling-related complications of elective endovascular coiling tend to occur either intraoperatively or are detected shortly after reversal of anesthesia. Further investigation with a larger cohort may help to guide important preoperative communication with patients and identify a select group of patients who may not necessarily require prolonged admission to hospital for observation.
