Introduction: We report a patient treated successfully via endovascular surgery within 24h after intravenous thrombolysis using recombinant tissue plasminogen activator for acute cervical internal carotid artery occlusion.
Presentation Of Case: A 68-year-old man was admitted to our hospital. Neurological examination revealed severe left-sided motor weakness. Magnetic resonance imaging showed no cerebral infarction, but magnetic resonance angiography revealed complete occlusion of the right internal carotid artery. Systemic intravenous injection of recombinant tissue plasminogen activator was performed within 4h after the onset. But, magnetic resonance angiography still revealed complete occlusion. Revascularization of the right cervical internal carotid artery was performed via endovascular surgery. The occluded artery was successfully recanalized using the Penumbra System(®) and stent placement at the origin of the internal carotid artery. Immediately after surgery, dual antiplatelet therapy (aspirin and clopidogrel) was initiated, and then cilostazol was added on the following day. Carotid ultrasonography and three-dimensional computed tomographic angiography at 14days revealed no further obstruction to flow.
Discussion: When trying to perform emergency carotid artery stenting within 24h after intravenous recombinant tissue plasminogen activator administration, several issues require attention, such as the decisions regarding the type of stent and embolic protection device, the selection of antiplatelet therapy and the methods of preventing hyperperfusion syndrome.
Conclusion: Emergency carotid artery stenting for the acute internal carotid artery occlusion may be considered a safe procedure in preventing early stroke recurrence in selected patients.

Introduction In the realm of Carotid Artery Stenting (CAS), various access methods such as Transfemoral access (TFA), Transradial Artery access (TRA), and Transbrachial access (TBA) have been employed. While TFA is widely established, TRA and TBA offer alternative options. TBA lacks comprehensive studies, and there is a notable lack of comprehensive evidence systematically evaluating its outcomes.

Aim: Ischemic stroke remains one of the leading causes of death and disability worldwide and ca-rotid stenosis is the leading etiology of ischemic strokes of non-cardiac origin. The chronic inflammatory process and pro-inflammatory state in carotid stenosis seem to be the most im-portant underlying factor in carotid occlusion. In addition to medical therapy and carotid ar-tery stunting (CAS) in the treatment of carotid stenosis, carotid endarterectomy (CEA) is the main surgical treatment of carotid stenosis and its prognosis is the main subject of our study.

The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

Acute ischemic stroke, a medical emergency caused by reduced cerebral blood flow, results in brain cell damage. While commonly associated with older individuals, strokes can also occur in young and middle-aged adults, posing significant socio-economic and health challenges due to the long-term impact of the condition. This poses significant socio-economic and health challenges because stroke is a leading cause of disability and mortality.

Objective: To develop a machine learning-based model for predicting the clinical efficacy of acupuncture intervention in patients with upper limb dysfunction following ischemic stroke, and to assess its potential role in guiding clinical practice.
Methods: Data from 1,375 ischemic stroke patients with upper limb dysfunction were collected from two hospitals, including medical records and Digital Subtraction Angiography (DSA) reports. All patients received standardized acupuncture treatment.
