Aims and objectives
Endovascular treatment has become an established treatment for ruptured intracranial aneurysms (1).
Aneurysms treated with endovascular technique have potentially rebleed.
MR angiography has been performed by several groups to monitor treated aneursyms (2-3).
In this study we show MR angiography follow-up of ruptured intracranial aneurysms endovasculary treated at our institution.
Methods and materials
From January 2007 to December 2013,
135 patients underwent endovascular treatment of ruptured intracranial aneurysms at our institution.
We established a surveillance protocol based on MRI for these patients.
MR angiographies were performed on 1.5T system (Signa,
GE Medical System,
Milwaukee,
WI) with a standard head coil.
The protocol included a cerebral MRI and gadolinium-enhanced MR angiography at 6,
12,
24 and 60 months after the procedure.
MR studies were reviewed by both diagnostic and interventional neuroradiologists.
MR findings were scored with the Raymond-Roy Classification...
Results
A total of 135 aneurysms were endovascular treated and were followed by using MR angiography.
The aneurysms were located on the anterior circulation in 129 patients (95.55%) and in the posterior circulation in 6 patients (4.44%).
The aneurysms ranged from 2 mm to 30 mm.
Aneurysms were treated with coils in 97 patients (71.85%); balloon and / or stent assistance for coil embolization was used in 38 patients (28.15%).
Initially,
ASD post treatment demonstrated 72 (53.33%) complete obliterations,
32 (23.7%) residual necks,
and 31 (22.96%)...
Conclusion
Endovascular treatment has become an established treatment for aneurysmal subarachnoid hemorrhage.
MR angiography is an good method to track endovascular treated aneurysms to confirm stability and monitor aneurysm recanalization.
MR angiography is a non-invasive imaging technique useful for long-term aneurysms follow-up.
