From: Safety and efficacy of the novel Alpha stent for the treatment of intracranial wide-necked aneurysm
Visibility of the stent and adjacent vessels on TOF-MRA. (A) 3-dimensional rotational angiogram of left ICA shows a saccular wide-necked aneurysm at the paraclinoid segment. (B) Control angiogram after stent-assisted coil embolization reveals small aneurysmal neck remnant. (C) TOF-MRA taken 6Â months after the procedure shows a residual neck remnant (white arrow) and a significant reduction of the in-stent signal (white arrowhead). A black arrowhead indicates less in-stent signal reduction in the contralateral ICA, where Neuroform Atlas was previously deployed. (D) 3-dimentional rotational angiogram of left ICA shows a 8-mm aneurysm at the ICA-posterior communicating artery junction. (E) Control angiogram after stent-assisted coil embolization reveals the preservation of posterior communicating artery flow. (F) TOF-MRA taken 6Â months after the procedure shows in-stent signal reduction but a patent posterior communicating artery (white arrowhead).
