Mechanical Thrombectomy Using Transradial Access in a Variation of the Origin of the Brachiocephalic Trunk and Left Common Carotid Artery by the Common Ostium from the Aortic Arch

The paper describes a clinical case of successfully applying a transradial access during mechanical thrombus extraction in a patient in the acutest stage of ischemic stroke with a congenital anatomical feature (the left common carotid artery and brachiocephalic trunk with the common ostium from the aortic arch).
X-ray endovascular interventions were performed in an operating room equipped with a digital angiographic unit including an Axiom Artis dTA flat detector (Siemens Medical System).
Mechanical recanalization for acute occlusion of the M2 segment of the left middle cerebral artery (MCA) was carried out using a right radial access into and catheterization of the left internal carotid artery. A stent retriever was inserted into the occlusion area through a microcatheter and was opened. Double thrombus extraction from the left MCA was made using the stent retriever to restore TICI 2B blood flow. There were no signs of dissection, thrombosis, or distal thromboembolism.
