Digital Substraction Angiography Diagnosis and Interventional Therapy of Intracranial Aneurysm

Objective:To sum up the application of digital subtraction angiography diagnosis of intracranial aneurysm and the experience of embolization of intracranial aneurysm with Guglielmi detachable coil(GDC).Methods:Sixty case were examined with digital subtraction angiography and the signs of intracranial aneurysm were summarized,and 8 case was embolized with GDC.Result:Among the 60 case,there were 33 aneurysms in 26 case,among the 33 aneurysm there were 21 cases mono-episode and 5 cases multi-episode;12 aneurysms involved the posterior communicating artery,11 the internal carotid artery,7 the anterior communicating artery,3 the middle cerebral artery;16 bladder shape,5 fusiform in shape,4 was calabash shap el,globular shap el and other 4 aneurysms shapeless;the diameter of the aneurysms between 2-21mm;8 cases was accompanied with cerebral vessels spasm,7 cases thrombosis.Among the 8 intracranial aneurysms embolized with GDC,in 5 case the cevity of aneurysms were 100 percent enbolized,2 cases were embolized 95-99%,1 case were embolized 80-90%;1 case the coil end protruding and 1 case over-embolized.Conclusion:The digital substraction angiography was a indispensable examination in making there final diagnosis intracranial aneurysm ,and it was a new therapeutic method with embolization of intracranial aneurysm with guglielmi detachable coil.
