Abstract
Background: The incidence of concomitant carotid artery stenosis and unruptured intracranial aneurysm (UIA) has been reported to be between 3% and 5%. The rupture risk of UIA measuring <7 mm is very low according to International Study of Unruptured Intracranial Aneurysm data. However, there may be a potential risk of aneurysm rupture after carotid artery revascularization because of increased cerebral blood flow. The aims of this study were to investigate the incidence of concomitant UIA in patients who needed carotid artery intervention and to survey the incidence of aneurysm rupture after treatment. Methods: Between October 2004 and December 2009, 114 patients with severe carotid artery stenosis were treated in our hospital (69 carotid endarterectomies and 45 carotid artery stentings). Cerebral angiography and medical records were reviewed retrospectively. Results: Cerebral angiography revealed seven asymptomatic UIAs in six patients (5%, 6/114). Of them, four patients underwent carotid endarterectomy and two underwent carotid artery stenting. All patients were male, and the mean age of the patients was 72 years (range, 67-79 years). Aneurysm size ranged between 2.3 and 4.0 mm. Two patients had UIAs on the same side of the treated carotid artery, whereas others developed UIAs on the contralateral side. There was no periprocedural aneurysm rupture. During follow-up (mean: 18 months, 5-31 months), two patients died from other causes, and no rupture of aneurysm occurred in any of the patients. Conclusion: In our series, the carotid artery revascularization did not have an effect on the natural course of small-sized asymptomatic UIA.
