INTERVENTIONAL TREATMENT OF INTRACRANIAL ANEURYSMS

Objective: To investigate the clinical effects and relevant problems of the embolization of intracranial aneurysms by using GDC, and meanwhile, to assess the value of rotational DSA in the interventional therapy of intracranial aneurysms.Methods: 18 patients with 20 intracranial aneurysms received endovascular embolization with GDC. Conventional anteroposterior, lateral views of DSA and rotational DSA were respectively performed in 20 aneurysms before operation. Images were compared for shape and size of the aneurysm and visibility of the aneurismal neck, and meanwhile, an ideal working view from rotational DSA was used in endovascular treatment of aneurysms. Results: No mortality occurred in our group. In 20 embolized aneurysms, 18(90%) were totally occluded, 2(10%) were subtotally occluded. Among 20 aneurysms, conventional DSA examination could not clarify shape and size of 3(3/20) aneurysms, and the vascular branch including the aneurysmal neck could not be clarified in 7 (7/20) aneurysms . However, shape and size of 20 aneurysms could be clarified after using the rotational DSA, and meanwhile, visibility of the aneurysmal neck and vascular branch could be identified with the rotational DSA in 19 aneurysms, and visibility of aneurysmal neck of 1(1/20) aneurysm could not be identified. Statistical analysis showed that rotational DSA provided better definition of the aneurysmal neck and greater clarity of aneurysms than did DSA. Conclusion: Rotational DSA often allows better visibility of vascular branch and aneurysmal neck, offering a ideal working view, the diameter of the first coil and correct plan for endovascular treatment. The endovascular embolization with GDC is a safe and effective method for treatment of the intracranial aneurysms.\;
