Vertebro-Vertebral Arteriovenous Fistulae: A Case Series of Endovascular Management at a Single Center.

Objective: Vertebro-vertebral arteriovenous fistulae (VVFs) are a rare disorder characterized by a direct shunt between the extracranial vertebral artery and the veins of the vertebral venous plexus. This study aims to comprehensively review the characteristics and outcomes of endovascular treatments for VVFs at our center.

Methods: A retrospective review was conducted on 14 patients diagnosed with a VVF who underwent endovascular treatment at Siriraj Hospital from January 2000 to January 2023.

Treatment Outcomes of Mechanical Thrombectomy in Patients with Acute Posterior Circulation Stroke.

 The benefits of mechanical thrombectomy (MT) in patients with acute posterior circulation stroke remain unclear. Currently, there is no evidence from randomized control trials to show the safety and effectiveness of MT in patients with posterior circulation stroke. This study was to evaluate the treatment outcomes of MT in posterior circulation stroke patients enrolling in our hospital during 2010 to 2020.

Infundibular dilatation perforating vessel of anterior communicating artery.

Background: Infundibular dilatation at cerebral arteries is primary located at the posterior communicating artery. This report describes a rare case of infundibular dilatation perforating the branch of an anterior communication artery (AcomA) which mimicked an AcomA aneurysm.

Case Description: The 54-year-old female presented with acute headache in the left temporal area with the right hemianesthesia.

Success Rate of Simple Coil Embolization in Wide-Neck Aneurysm with Aneurysmal Shoulder.

Background And Objective: Wide-necked intracranial aneurysm (WIA) is one of the challenging diseases for neuro-interventionist to treat by simple coiling technique. The purpose of this study is to identify the morphology associated with successful simple coil embolization in wide neck aneurysm patients.

Materials And Methods: Between January 2002 and August 2018, 102 patients with total 115 ruptured or unruptured WIA which received endovascular treatment were retrospective reviewed.

Efficiency of Endovascular Therapy for Bilateral Cavernous Sinus Dural Arteriovenous Fistula.

Background: The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established because of the complexity in the number of fistula tracts and their behavior, which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes.

Methods: The data were analyzed from 165 consecutive patients diagnosed with CS-dAVF from January 2005 to September 2018.
