A 55-year-old man (patient 1) with a ruptured anterior communicating artery (AcomA) aneurysm. A, Initial angiogram shows a wide-neck AcomA aneurysm associated with the median artery of the corpus callosum. B, Balloon is positioned across the aneurysm neck and the first coil is inserted into the aneurysm with the balloon inflated. The first coil prolapses into the right A2 when the balloon is deflated (arrow). C, The deployed but undetached stent is positioned in the left A1 and right A2 segments from the left (arrowhead); the balloon is placed in the left A2 (arrow) and the microcatheter into the aneurysmal sac. D, Postprocedural angiogram demonstrates complete aneurysm occlusion after stent retrieval.

A 52-year-old woman (patient 7) with a complex MCA aneurysm. A and B, Initial angiogram shows a broad-based, bilobed MCA bifurcation aneurysm. An additional paraophthalmic aneurysm is noted. C, The undeployed stent is positioned across the superior trunk (arrow) and the balloon placed to protect the inferior trunk from coil migration. A vasospasm in the superior division of MCA was observed. D, The stent is deployed (arrow), and aneurysm packing is performed. The distal stent markers appear to be outside the vessel wall, an appearance that is related to vasospasm. E and F, A thromboembolic adverse event occurred during inflation of the balloon in the inferior MCA branch, which resulted in no clinical disability.
