Combined endovascular stent implantation and endosaccular coil placement for the treatment of a wide-necked vertebral artery aneurysm: technical case report.
OBJECTIVE
We describe a case in humans of the combined application of endovascular stent placement and Guglielmi detachable coil packing in the management of a wide-necked intracranial aneurysm.


METHODS
A 56-year-old woman suffered a subarachnoid hemorrhage secondary to a large wide-necked left vertebral artery aneurysm. Because of the size of the neck of the aneurysm and the extent of its calcification evident on computed tomographic scans, it was deemed unsuitable for surgical intervention or for conventional endovascular coiling. Instead, a combined surgical and endovascular therapy was instituted.


METHODS
The left vertebral artery was surgically exposed and cannulated to allow for the placement of an endovascular stent across the neck of the aneurysm to act as a buttress against which Guglielmi detachable coils could be packed. The patient suffered no ill effects as a result of this procedure and made a slow but steady recovery.


CONCLUSIONS
This report describes a case of a wide-necked intracranial artery aneurysm treated using a combination of endovascular stent implantation across an aneurysm neck and endosaccular coil placement to obliterate the aneurysm. The technique described provides another treatment to better manage the difficult entity of wide-necked intracranial aneurysms that may be unsuitable for clipping.
