BACKGROUND The authors report a case in which mechanical thrombectomy and carotid artery stenting (CAS) were performed for acute cerebral infarction with free-floating thrombosis (FFT) in left internal carotid artery (ICA) stenosis. Good results were obtained. OBSERVATIONS A 63-year-old man developed sudden disturbance of consciousness and right hemiplegia. He was transported to the authors’ hospital by an emergency vehicle. Head magnetic resonance imaging showed acute cerebral infarction in the left middle cerebral artery region, and magnetic resonance angiography showed poor vascular flow beyond the left ICA. Emergency angiography revealed severe stenosis at the origin of the left ICA and a free-floating thrombus attached to the stenosis and extending to the peripheral side. Percutaneous transluminal angioplasty (PTA) was performed on the stenosis with proximal protection, the thrombus was aspirated under reversal flow, and CAS was performed without exacerbation of clinical symptoms. LESSONS PTA, thrombus aspiration, and CAS under reversal flow may be effective treatments for FFT caused by ICA stenosis.

First Pass

Background and Purpose: Achieving complete revascularization after a single pass of a mechanical thrombectomy device (first pass effect [FPE]) is associated with good clinical outcomes in patients with acute ischemic stroke due to large vessel occlusion. We assessed patient characteristics, outcomes, and predictors of FPE among a large real-world cohort of patients (Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke registry). Methods: Demographics, clinical outcomes, and procedural characteristics were analyzed among patients in whom FPE (modified Thrombolysis in Cerebral Infarction 2c/3 after first pass) was achieved versus those requiring multiple passes (MP). Modified FPE and modified MP included patients achieving modified Thrombolysis in Cerebral Infarction 2B-3. Primary outcomes included 90-day modified Rankin Scale (mRS) score and mortality. Results: Among 984 Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke patients, 930 had complete 90-day follow-up. FPE was achieved in 40.5% (377/930) of patients and MP in 20.0% (186/930). Baseline characteristics were similar across all groups. The FPE group had fewer internal carotid artery occlusions compared with MP ( P =0.029). The FPE group had faster puncture to recanalization time ( P ≤0.001), higher rates of 90-day mRS score of 0 to 1 (52.6% versus 38.6%, P =0.003), mRS score of 0 to 2 (65.4% versus 52.0%, P =0.003), and lower 90-day mortality compared with the MP group (12.0% versus 18.7%, P =0.038). Similarly, compared with modified MP patients, the modified FPE group had fewer internal carotid artery occlusions ( P =0.004), faster puncture to recanalization time ( P ≤0.001), and higher rates of 90-day mRS score of 0 to 1 ( P =0.002) and mRS score of 0 to 2 ( P =0.003). Conclusions: Our findings demonstrate that FPE and modified FPE are associated with superior clinical outcomes.

Stroke Risk Factors

Large cerebral infarctions have high morbidity and mortality. Patients with large cerebral infarctions may have recurrent ischemia as high as 8.1% within 7 days; highest among other types of strokes. Data regarding risk factors for large cerebral infarction in Asian populations are still scant. All adult (age ≥15 years old) patients with the diagnosis of thrombotic ischemic stroke who were treated at Srinagarind Hospital, Khon Kaen University, Thailand from January 2012 to December 2013 were studied. Large cerebral infarctions are defined by clinical criteria of having cerebral cortical impairment, brain stem or cerebellar dysfunction with infarction sizes of more than 1.5 cm. The association of various stroke risk factors and large infarction strokes were calculated using multiple logistic regression analysis. There were 276 thrombotic stroke patients who met the study criteria; classified as large cerebral infarctions in 59 patients (21.38%) and small cerebral infarctions in 217 patients (78.62%). Baseline characteristics and risk factors for stroke were comparable between both groups. The large cerebral infarction group had a significantly larger proportions of right internal carotid artery stenosis, plaques on the left side, left internal carotid artery stenosis, and internal carotid artery stenosis at any side than the small cerebral infarction group. Among various stroke risk factors, only internal carotid artery stenosis at any side was the only significant factor associated with large cerebral infarction with an adjusted odds ratio of 11.14 (95% CI: 3.46, 35.82). In conclusion, significant internal carotid artery stenosis is associated with large cerebral infarction.
