Background:
Paraclinoid carotid aneurysm is widely treated with coil embolization. However, all paraclinoid carotid aneurysms cannot be obliterated by the endovascular approach.
Methods:
Our direct surgical procedure was presented. The clinical data of surgically treated paraclinoid carotid aneurysms were retrospectively reviewed.
Results:
One hundred ninety paraclinoid carotid aneurysms in 181 patients were directly obliterated at the Shinshu University Hospital and its affiliated hospitals between 1991 and 2013.
Conclusions:
Direct surgical repair of the paraclinoid carotid aneurysm is still useful, even in the era of endovascular treatment.
