Fenestrierung von Arterien

Magnetresonanz-Angiographie

(MRA) in Maximum Intension Projection (MIP)-Darstellung einer gefensterten Arteria basilaris. Die Aa. vertebrales sind asymmetrisch angelegt. Unmittelbar nach dem Zusammenfluss bildet die A. basilaris einen Ring. Es wird eine erhöhte Inzidenz von Aneurysmen an dieser Stelle beschrieben.

Transitory

ischemic attack associated with a rare fenestration of the cervical segment of the internal carotid artery: a case report. Magnetic resonance angiography performed 2 weeks after the initial event revealed a fenestration of the cervical ICA (A white arrow). Multiple transversal sections showed regular filling of the fcICA with contrast medium in both lumina (B1–3 white arrows), where paracoronal reformations using a maximum intensity technique showed that both lumina were comparably well developed (C1–3 white arrows)

Transitory

ischemic attack associated with a rare fenestration of the cervical segment of the internal carotid artery: a case report. Volume rendering of magnetic resonance angiography data (A, B) and use of common edge enhancement tools (C) did not show any sign of a dissection or any other severe degradation of the fcICA vessel walls

Common and

uncommon intracranial arterial anatomic variations in multi-detector computed tomography angiography (MDCTA). What radiologists should be aware of. a CTA (VRT 3D reconstructions) shows a proximal basilar artery fenestration (red arrow). b CTA (VRT 3D reconstructions) shows an Acom artery fenestration (red arrow)
