Background: Data on arterial recanalization after IV t-PA treatment are rare. IMS-3 allows the study of variables affecting arterial recanalization after IV t-PA in acute ischemic stroke patients with CTA-proved major artery occlusions. Methods: Of 656 acute ischemic stroke patients in IMS-3, 306 were examined with baseline CTA and randomized either to IV t-PA (N=95) or to IV t-PA followed by digital subtraction angiography (DSA) and endovascular therapy (EVT) (N=211). Comparison of baseline CTA to DSA within 5 hours of stroke onset assessed early arterial recanalization after IV t-PA. A central core lab categorized DSA vessel occlusion as “no, partial, or complete”. We studied the association between arterial occlusion sites on baseline CTA with early recanalization for the endovascular group and analyzed its impact on clinical outcome at 90 days. Results: In the EVT group, 22 patients (10.4%) had no CTA intracranial occlusions, but 1 extracranial occlusion; 42 patients (19.9%) had occlusions of intracranial internal carotid artery (ic-ICA); 10 patients (4.7%) had tandem occlusions of the cervical ICA and middle cerebral artery (MCA); 95 patients (45.0%) had MCA-trunk (M1) occlusions, 33 patients (15.6%) had M2 occlusions, 3 patients (1.4%) had M3/4 occlusions, and 6 patients (2.8%) occlusions within posterior circulation. Partial or complete recanalization occurred in 28.6% of patients before DSA and was marginally associated with occlusion site (p=0.0525) (8 patients (19.0%) with ic-ICA occlusion, 0 patients with tandem ICA/MCA occlusions, 34 patients (35.8%) with M1 occlusions, 11 patients (33.3%) with M2 occlusions, 0 patients with M3/4 occlusions, and 1 patient (16.7%) with occlusion within posterior circulation). Three CTA negative patients had intracranial occlusions on DSA. Thirty-two patients (59.3%) with early recanalization achieved mRS of 0-2 at 90 days compared to 51 patients (38.4%) without early recanalization (p=0.0099). There was no relationship between early recanalization and time to IV t-PA or mean t-PA dose. Conclusion: Before EVT, IV rt-PA may facilitate arterial recanalization and better clinical outcome in about one third of patients.

Purpose Acute ischemic strokes caused by steno-occlusive lesion of the cervical internal carotid artery are associated with poor clinical outcome. We evaluated the clinical efficacy of emergent carotid artery stenting for the management of these lesions. We compared the clinical outcomes regarding the intracranial lesion, namely tandem occlusions versus isolated cervical internal carotid artery occlusion. Materials and methods We retrospectively reviewed patients with acute ischemic stroke who underwent carotid artery stenting for cervical internal carotid artery steno-occlusive lesion between 2011 and 2018. After dividing the patients into two groups according to the presence or absence of intracranial lesions (tandem group and isolated cervical group), we analyzed demographic data, angiographic findings, and clinical outcomes. A modified Rankin Scale score ≤2 was defined as a favorable clinical outcome. Results Of 75 patients, 46 patients (61.3%) had tandem lesions, and the remaining 29 had only cervical internal carotid artery steno-occlusive lesion. Successful stenting was performed in all patients with favorable clinical outcomes (64.0%). Successful reperfusion score (thrombolysis in cerebral infarction ≥2 b) was 84.0%; tandem group (76.1%) versus isolated cervical group (96.6%) of cases. Mean modified Rankin Scale score at 90-days was 2.09. The rate of favorable clinical outcome showed no statistically significant difference between the two groups ( p = 0.454). Conclusions Endovascular treatment in patients with acute ischemic stroke due to cervical internal carotid artery steno-occlusive lesion is a technically feasible and clinically effective intervention regardless of intracranial occlusion. Therefore, we recommend endovascular treatment regardless of the presence of concomitant intracranial artery occlusion for patients with acute ischemic stroke caused by cervical internal carotid artery steno-occlusive lesion.

Giant cell arteritis (GCA) is a common type of vasculitis and may present various forms. Ischemic stroke is one of the complications and sometimes the first symptom of this disease. We want to present the case of a 58-year-old female patient with suspected GCA who suffered from recurrent ischemic strokes due to progressive stenosis of the internal carotid arteries. This site of manifestation is rare but indicative of GCA. The patient was first treated with corticosteroids and methotrexate later with tocilizumab. Facing progressive hemodynamic impairment, an extra-intracranial-bypass-surgery was performed. Although inflammatory activity was reduced, new strokes occurred.

Abstract Background: Moyamoya syndrome is chronic stenoocclusive disease involving the intracranial internal carotid arteries and their proximal branches along with an associated condition, such as hyperthyroidism1. The concurrence of moyamoya and Graves’ disease is rare. Ischemic stroke in moyamoya syndrome is postulated to be precipitated by thyrotoxicosis-induced hemodynamic instability. Clinical Case: A 63-year old Korean female with history of moyamoya disease with two prior ischemic strokes, hypertension and type 2 diabetes mellitus presented to the ER with 6 hours of left leg weakness and involuntary arm movements. A code stroke was activated and neurologic examination was notable for left leg paresis and left arm stereotypy. CT head showed loss of gray-white matter differentiation in the right frontal lobe concerning for acute ischemia. CT angiography of the head and neck noted diffuse stenosis of intracerebral vasculature and significant stenosis of the cavernous and supraclinoid portions of the internal carotid arteries. MRI brain later confirmed an acute infarct in the right ACA distribution. Neuroimaging incidentally showed a multinodular goiter with a 1.7 cm right thyroid nodule. Subsequently TSH was obtained and resulted as <0.030 mcIU/mL (0.27-5.00 mcIU/mL) with a reflex FT4 of >7.00 ng/dL (0.6-1.8 ng/dL). A review of her prior TFTs showed biochemical euthyroidism. Due to iodinated contrast administration on admission, RAIU scan was deferred. Thyroid ultrasound showed multinodular goiter with diffuse increased vascularity and multiple TI-RADS 4 and 5 nodules bilaterally. On further questioning, the patient reported tachycardia, diarrhea, weight loss and decreased appetite prior to hospitalization. A diagnosis of Graves’ disease was confirmed with TSI of 70.7 IU/L (0.00-0.55 IU/L). She was started on methimazole 20 mg twice daily and propranolol 20 mg q6h. FT4 downtrend from >7.00 to 3.3 ng/dL at time of discharge. Following four weeks of methimazole 20 mg daily, FT4 normalized to 1.70 ng/dL. The patient chose to continue antithyroidal drug therapy for treatment of Graves’ disease. Conclusion: Thyroid function assessment should be considered when evaluating a patient with moyamoya and acute ischemic stroke. If moyamoya syndrome associated with Graves’ disease is identified, treatment should be aimed at maintenance of euthyroidism. Reference: 1. Scott RM, Smith ER. Moyamoya disease and moyamoya syndrome.

Background : The clot burden score (CBS) is a scoring system used in acute ischemic stroke (AIS) to predict patient outcome and guide treatment decision. However, CBS is not routinely practiced in many institutions. This study aimed to investigate the feasibility of CBS as a relevant predictor of good clinical outcome in AIS cases. Methods:  A retrospective data collection and review of AIS patients in a teaching hospital was done from June 2010 until June 2015. Patients were selected following the inclusion and exclusion criteria. These patients were followed up after 90 days of discharge. The Modified Rankin scale (mRS) was used to assess their outcome (functional status). Linear regression Spearman Rank correlation was performed between the CBS and mRS. The quality performance of the correlations was evaluated using Receiver operating characteristic (ROC) curves. Results: A total of 89 patients with AIS were analysed, 67.4% (n=60) male and 32.6% (n=29) female. Twenty-nine (29) patients (33.7%) had a CBS ?6, 6 patients (6.7%) had CBS <6, while 53 patients (59.6%) were deemed clot free. Ninety (90) days post insult, clinical assessment showed that 57 (67.6%) patients were functionally independent, 27 (30.3%) patients functionally dependent, and 5 (5.6%) patients were deceased. Data analysis reported a significant negative correlation (r= -0.611, p<0.001). ROC curves analysis showed an area under the curve of 0.81 at the cut-off point of 6.5. This showed that a CBS of more than 6 predicted a good mRS clinical outcome in AIS patients; with sensitivity of 98.2%, specificity of 53.1%, positive predictive value (PPV) of 76%, and negative predictive value (NPV) of 21%. Conclusion: CBS is a useful additional variable for the management of AIS cases, and should be incorporated into the routine radiological reporting for acute ischemic stroke (AIS) cases.
