ABSTRACT
OBJECTIVE: The aim of the study is to compare the efficacy and safety of angioplasty alone with acute stenting for acute tandem occlusions (TO) due to internal carotid artery atherosclerotic.
METHODS: We identified 112 patients who underwent an endovascular treatment (EVT) for acute tandem internal carotid artery occlusions from the prospectively maintained registries 5 comprehensive stroke centers. The study cohort included 75 patients with underlying atherosclerotic lesion of the extracranial internal carotid artery, forty-five in the balloon angioplasty (BA) alone group and 30 in the acute stenting (AS) group. Using propensity score matching analysis, forty-four patients were matched. Clinical characteristics and outcome data were compared between two groups.
RESULTS: The successful reperfusion immediately post procedure [72.7% (16/22) vs. 77.3% (17/22), P = 1.0] and 90-days good functional outcome [54.5% (12/22) vs. 59.1% (13/22), P = 0.761] were not significantly different between the BA group and AS group. There was also no significant difference in the rate of symptomatic intracranial hemorrhage [13.6% (3/22) vs. 9.1% (2/22), P = 1.00] and restenosis of ICA (>50%)[27.3% (6/22) vs. 22.7% (5/22), P = 0.728] between 2 groups. Patients in the BA group appear to have a numerically lower rate of asymptomatic intracranial hemorrhage [40.9% (9/22) vs. 50% (11/22), P = 0.545] and mortality [0 vs. 9.1% (2/22), P = 0.488] than in the AS group, although there were not statistically significant.
CONCLUSION: Among TO patients with etiology of large vessel atherosclerosis, no statistical differences in outcome are identified between balloon angioplasty alone versus acute stenting. Future randomized controlled trials are warranted.
