Neuroform stent-assisted coil embolization at a low volume center is efficacious and does not increase procedural risk with optimal operator experience.

A 74-year-old male developed cervical carotid artery psuedoaneurysm 8 months after carotid endarterectomy. The patient was successfully managed with dual implantation of flow-diverter and conventional carotid stent. Flow-diverter was placed across the neck of pseudoaneurysm to provide flow diversion while carotid stent was implanted within the lumen of the expanded flow-diverter to approximate and hold the flow diverter proximal and distal to the pseudoaneurysm. Follow-up ultrasonography revealed complete resolution of the pseudoaneurysm.

Spontaneous high-flow vertebral arteriovenous shunts can be successfully occluded with Onyx/detachable coil embolization of the principle recipient veins.

The presence of normal branch vessels arising from the dome is a limitation for endovascular techniques. To the best of our knowledge, no prior description of a dual-microcatheter technique with selective catheter placement within an important intra-aneurysmal branch vessel has been published. The vital branch vessel was protected and the wide-neck aneurysm completely occluded. Novel placement of microcatheters further expands the range of complex configuration aneurysms amenable to endovascular coiling.

Fistulous cerebrovascular injuries can occur spontaneously, iatrogenically following surgical procedures, or can result as a consequence of penetrating trauma. To our knowledge, this is only the second reported case of blunt-trauma induced cervical vertebral artery arteriovenous fistula (AVF) formation in a 55-year-old male. This was successfully occluded with N-butyl cyanoacrylate (NBCA) embolization of the recipient vein and endovascular coil ligation of the vertebral artery.
