Background: Effectiveness of surgical revascularization in patients with chronic cerebral ischemia depends on restoration of circulation in the damaged artery. Modern methods do not take into account dynamic changes in cerebral perfusion after extra-intracranial microvascular anastomosis (EICMA) and do not allow timely localizing the areas of persistent perfusion deficit. We propose a new method for determining the tactics of surgical cerebral revascularization based on intraoperative MRI (iMRI) perfusion data.

Objective: BTO is the procedure performed to assess the collateral circulation within the Willis circle in a giant ICA aneurysm. An ICA occlusion after BTO is very rare. We present a case of an internal carotid artery occlusion as a complication of BTO that required urgent revascularization surgery.

Background And Purpose: Prasugrel (Pra) is a third-generation thienopyridine that inhibits platelet aggregation via irreversible blockade of P2Y12 receptors. While several published studies have examined the use of Pra and acetylsalicylic acid (ASA) in coronary and neurovascular stenting procedures, there is only anecdotal evidence regarding the use of Pra as single antiplatelet therapy (SAPT) in open surgical procedures. This topic has become important because previous studies have revealed that neurovascular devices with antithrombotic coatings can be implanted using non-invasive procedures in patients maintained on Pra SAPT.

Purpose: Carotid cavernous fistulas (CCFs) are abnormal connections between the cavernous sinus (CS) and carotid arteries. In direct CCFs, a transarterial route is often the preferred vascular access; in case of indirect CCFs, the complex anatomy of the feeder vessels and their extra-intracranial anastomosis makes the transarterial embolization challenging and often ineffective. The aim of this study was to review our experience with the transorbital approach to treat patients affected by CCF who have already experienced an endovascular failure procedure, in order to assess this salvage technique feasibility, by analyzing possible risks and complications.
