A case of fibromuscular dysplasia (FMD) of the internal carotid artery was treated by percutaneous transluminal angioplasty (PTA) using a Grüntzig balloon. A control angiographic study performed with intravenous digital subtraction angiography (IV DSA) showed a completely patent dilated vessel. This result, together with the total relief of clinical signs and symptoms, is evidence of the value of PTA in the treatment of FMD of the internal carotid artery.

Introduction: In the past decade, flow diverters (FDs) have increasingly been used to treat cerebral aneurysms with unfavorable morphology in which other endovascular techniques fall short of being as effective. In-stent stenosis (ISS) is one of the most puzzling and frequent risks of flow diversion therapy observed on follow-ups. This complication, although mostly placid in its clinical course, can have dire consequences if patients become symptomatic.

Objective: Endovascular mechanical thrombectomy (EVMT) is widely employed in patients with acute intracranial carotid artery occlusion (AIICAO). This study aimed to predict the outcomes of EVMT following AIICAO by utilizing anatomic classification of the circle of Willis and its relative position to the thrombus.
Methods: In this study, we retrospectively analyzed a cohort of 108 patients with AIICAO who underwent endovascular mechanical thrombectomy (EVMT) at Shaoxing People's Hospital.

Fibromuscular Dysplasia (FMD) is a nonatherosclerotic, noninflammatory vascular disorder predominantly affecting women aged 18 to 65 years. This case report highlights a 74-year-old female diagnosed with FMD incidentally during evaluation for deep vein thrombosis (DVT). Imaging revealed significant vascular anomalies, including a giant intracranial carotid aneurysm and a hypoplastic iliac vein with extensive collateral formation.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Background And Objective: Radiosurgery can serve as a primary, adjuvant, or salvage treatment modality for cavernous sinus tumors (CST), providing high tumor control. However, particularly with cavernous sinus expansion, there may be insufficient distance from the optic apparatus to perform radiosurgery safely. The internal carotid artery adjacent to the distal dural ring (ICAddr), when enhancing similarly to the CST, can be difficult to delineate, and can lead to over-contouring of target volume near the optic nerve and therefore increasing the risk of radiation-induced optic toxicity.
