Abstract Carotid artery angioplasty and stenting (CAS) has been shown to be equally effective as carotid endarterectomy (CEA) for carotid stenosis in both symptomatic and asymptomatic disease. 1 In patients who are considered high risk for endarterectomy, CAS is safe and effective. 2 While this is a common procedure, proper technique is crucial to ensure that the procedure is safe with minimal risk of stroke. This patient consented to treatment. The following is a video detailing the CAS procedure in a 77-yr-old male with a symptomatic 65% carotid stenosis (by NASCET criteria 3 ) in a patient with prior CEA.
Endovascular Coil Embolization of a Posterior Communicating Artery Aneurysm: 2-Dimensional Operative Video
Abstract Since the International Subarachnoid Aneurysm Trial, 1 endovascular treatment has been the favored treatment for appropriate ruptured intracranial aneurysms. While our endovascular technology has advanced to allow us to treat the majority of intracranial aneurysms, simple coil embolization is still the most common modality. This video demonstrates the fundamentals of aneurysm catheterization and coiling for safe treatment. In addition, the set-up and devices are detailed. This video is to add to the library of basic techniques that will aid a large number of practitioners. This patient consented to endovascular treatment. The video demonstrates endovascular coil embolization of a posterior communicating artery aneurysm in a 76-yr-old female who presented with a subarachnoid hemorrhage.

Common Femoral Artery Access: 2-Dimensional Operative Video
Abstract Vascular access for cerebral angiography has traditionally been performed via the common femoral artery. It is crucial to obtain safe access to prevent complications that could lead to limb ischemia, groin hematoma, or retroperitoneal hematoma. This is especially true in neurointervention as many patients are anticoagulated or have received intravenous thrombolytics prior to their intervention. Special attention to anatomic landmarks, both grossly and radiographically, can help to assure safe access. The patient consented for this procedure. This video details rapid but safe femoral artery access in a patient undergoing emergent thrombectomy.
