Arterial occlusion to treat basilar artery dissecting aneurysm

Abstract

Object

To explore the clinical feasibility of employing occlusion to treat basilar artery dissecting aneurysm.

Methods

One patient, male and 46 years old, suffered transient numbness and weakness on the right limbs. Cerebral angiography indicated basilar artery dissecting aneurysm. The patient underwent the stent-assisted coil embolization of aneurysm and the result is satisfactory. Digital subtraction angiography (DSA) reviews were performed at 1 month and 4.5 months, respectively after the operation and indicate that the basilar artery is unobstructed and there was no recurrence of the aneurysm. DSA review 1 year after the first treatment indicates the aneurysm recurrence, stent-assisted coils dense embolization of aneurysm was performed again and the result was satisfactory. Ten months after the second operation, DSA review found the basilar artery aneurysm recurrence again and occlusion of the basilar artery was performed.

Results

The basilar artery occlusion was effective. The bilateral posterior inferior cerebellar arteries and the bilateral posterior cerebral arteries are unobstructed. Five months of follow-up found that the patient recovered well. DSA reviews performed 5 months after occlusion indicate no recurrence of the aneurysm.

Conclusions

Occlusion to treat basilar artery dissecting aneurysm is clinically feasible, but surgical indications should be considered strictly.
