[Reconstructive endovascular treatment for symptomatic giant and fusiform aneurysm of vertebrobasilar artery with self-expandable stents].
OBJECTIVE
To reconstruct and affix symptomatic giant and fusiform aneurysms of vertebrobasilar artery by using self-expandable stents in 5 cases with an average volume 5.5 mm × 5.0 mm × 60.0 mm.


METHODS
The clinical data of 5 patients who were suffered from giant and fusiform aneurysms of vertebrobasilar artery between October 2007 and October 2009 were retrospectively analyzed. Under instructing of digital subtraction angiography (DSA) images deployed the LEO and Neuroform stents for reconstructing and affixing the deferent 5 giant fusiform aneurysms of vertebrobasilar artery. And assisted embolized with 3 Orbit coils for a ruptured aneurysm to stop bleeding at the same time.


RESULTS
The operative procedures were succeeded in all five cases. The damaged signs and symptoms of posterior group of cranial nerves disappeared in 3 cases by following 3 to 26 months. Trigeminal neuralgia in one case was markedly improved but a hemiparesis. One case with subarachnoid hemorrhage (SAH) showed no relapse evidence. Follow up DSA images in 3 cases demonstrated one case with a more rule modality in the part of aneurysm affixed by stent and proximal part of aneurysm in which no covering by stent revealed a mild to expand after 26 months review. And the images of postoperative DSA following 1 month and 4 months in another 2 cases displayed the imaging enlargement of part of the original aneurysm body shrink and shape the rules than the previous view.


CONCLUSIONS
The treatment of symptomatic huge fusiform vertebrobasilar aneurysms by using self-expandable stents is feasible, aneurysm growth is under control, short-term effects are positive.
