Abstract
Cerebral aneurysms in patients with extreme proximal tortuosity may contraindicate endovascular therapy as a result of both the approach and an inability to navigate a coil-compatible microcatheter into the aneurysm due to microcatheter length. We present a 72 year-old male with multiple medical comorbidities admitted with a grade 3, ruptured pericallosal aneurysm. Aortoiliac disease contraindicated a transfemoral approach and thus a 6 French 105 cm guide catheter was advanced through a 6 French short radial sheath into a bovine left common carotid artery. After straightening proximal access anatomy with an Amplatz wire to allow advancement of the guide catheter into the internal carotid artery, a 167 cm 0.013 in. headway duo was advanced through a 5 French Sofia through the guide catheter and "hubbed" to enter the aneurysm. The aneurysm was then successfully coil embolized with 4 Target Ultrasoft coils. This case illustrates the utility of a 167 cm microcatheter for coil embolization of a pericallosal aneurysm with significant proximal tortuosity via a transradial approach. Despite its 0.013 in. inner diameter and length, common Target coils were compatible and deployed without incident.
