Treatment experience of paraclinoid carotid micro-aneurysm

Objective To investigate the therapies choice of paraclinoid carotid micro-aneurysm.Methods Eighteen patients suffered from paraclinoid carotid microaneurysm,definitely diagnosed by clinical measures and images,were chosen in our study; their clinical data were retrospective analyzed; among them,4 cases suffered from carotid ophthalmic aneurysms,including 3 accepted endovascular treatment and 1 microsurgical clipping; 10 cases suffered from internal carotid artery posterior communicating artery aneurysm,and 3 of them got endovascular treatment and 1 microsurgical clipping; 3 cases had anterior choroidal artery aneurysm of internal carotid artery,including 1 received endovascular treatment and 2 microsurgical clipping; and one was diagnosed as having internal carotid artery bifurcation aneurysms and clipping was performed.Results One patient suffered from carotid ophthalmic aneurysm died from re-rupture after endovascular treatment.One patient suffered from internal carotid artery posterior communicating artery aneurysm died from re-rupture after stent assisted coil embolization.One suffered from internal carotid artery posterior communicating artery aneurysm got good recovery (a spring ring escaped when taking coil embolization of aneurysm,and microsurgical clipping was then performed).Others got well.Conclusion Micro-aneurysms located in supraclinoid intemal carotid arteries and ophthalmic artery can be performed stent assisted loose coil embolization,and others can be preferred craniotomy operation to clip the neck of aneurysms.
