Endovascular Coil Embolization of a Posterior Communicating Artery Aneurysm: 2-Dimensional Operative Video.

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.

Carotid Artery Angioplasty and Stenting: 2-Dimensional Operative Video.

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.

Common Femoral Artery Access: 2-Dimensional Operative Video.

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.

Placement of a Pipeline Embolization Device: 2-Dimensional Operative Video.

Flow diversion has been a game-changer in the treatment of wide-neck large and giant cavernous and supraclinoid internal carotid artery (ICA) aneurysms as well as large vertebral artery aneurysms. Prior to their existence, carotid sacrifice or clipping with or without external to internal carotid artery bypass was the mainstay of treatment. Prior to flow diversion, endovascular coil embolization was often not effective as a stand-alone treatment because of the fact that many of these aneurysms present with symptoms created by mass effect on the cavernous sinus cranial nerves by the aneurysm.
