Application of dual vessel fusion technique in interventional treatment of complex anterior communicating artery aneurysms / 医学研究生学报

ABSTRACT

Objective Intravascular interventional embolization has become the preferred method for the treatment of anterior communicating artery aneurysms.The purpose of this paper was to study the guiding significance of dual vessel fusion technique for in -terventional surgery of complex anterior communicating artery aneurysms. Methods A retrospective analysis was conducted on the clinical data of 31 patients with complicated anterior communicating artery aneurysms in our department from March 2015 to June 2016. All patients underwent two-vessel fusion, DSA angiography, and three-dimensional reconstruction of unilateral internal carotid artery and the images were compared to identify whether the aneurysm met the true size,the exact convergence point of bilateral A 1 and ante-rior communicating artery, anterior communicating artery aneurysm and anterior communicating artery and so on. Results There were 31 cases identified by dual vessel fusion technique on the consistency of aneurysms to true volume and 28 cases by three-dimensional reconstruction of unilateral internal carotid artery.There were 31 cases identified by dual vessel fusion technique on the exact convergence point of bilateral A 1 and anterior communicating artery and 9 cases by DSA angiography.There were 31 cases identified by dual vessel fusion technique on variations of anterior communicating artery complex and 24 cases by DSA angiography.There were 27 pa-tients who attained the optimal DSA machine projection angle by the dual vessel fusion technique which was the same as that of the unilateral internal carotid artery,in addition,the other 4 cases got better optimal DSA machine projection angle than those by three-dimensional reconstruction of unilateral internal carotid artery. Conclusion The dual vessel fusion technique helps surgeons to fully understand the anatomical relationship between anterior communicating artery complex and aneurysm,which has important guiding significance in making surgical strategies for complicated anterior communicating artery aneurysms,selecting embolization work angles and real-time observation during embolization.
