Vertebro-vertebral arteriovenous fistula (VV-AVF) is an uncommon vascular disorder characterized by an abnormal direct connection between the extracranial vertebral artery (VA), as well as the first and second branches of subclavian arteries, and the draining veins of the paravertebral venous plexus. Endovascular occlusion or surgical ligation of the high-flow arteriovenous fistula is the main goal of treatment for VV-AVF, but there are no guidelines for the best treatment to date. Endovascular treatment is the primary treatment procedure due to its safety, effectiveness, and simplicity.

The treatment of indirect carotid-cavernous fistula (CCF) poses a unique challenge. Currently, endovascular interventions remain the principal treatment option with high cure rates and acceptable safety profiles. The anatomical characteristics of individual cases determine the optimal vascular access routes (transvenous vs.

Background: The evolution of embolic agents necessitates the use of microcatheters compatible with dimethyl sulfoxide (DMSO), with detachable tip microcatheters (DTMs) emerging as a significant innovation aimed at reducing the risk of catheter entrapment in embolization procedures. This study aims to compare the efficacy, safety, and DMSO compatibility of DTMs with non-detachable tip microcatheters (Non-DTMs) in the context of embolization treatments for neurovascular diseases.
Method: Following PRISMA guidelines, a systematic literature search was conducted across PubMed, Scopus, Embase, and Web of Science databases until February 25, 2024.

Middle meningeal artery embolization (MMAE) is an effective adjunctive treatment for chronic subdural hematomas and carries a low risk of significant complications.1 Here we describe the management of a retained and fractured microcatheter following liquid embolic MMAE. A patient with chronic recurrent subdural hematomas underwent bilateral MMAE with Onyx liquid embolic material (Medtronic).

A 24-year-old male was admitted with progressive cervical hypesthesia, tetraparesis, dyspnea, and a history of craniofacial fracture. Spinal magnetic resonance imaging (MRI) showed brainstem edema extending to the thoracic spine with multiple prominent perimedullary vascular structures. Cerebral digital-substraction angiography revealed Barrow type A carotid-cavernous fistula.
