Objective:
To analyze the characteristics of aneurysms difficult to be treated by endovascular interventional therapy and report the results of operation.
Methods:
27 patients with 33 intracranial aneurysms transferred from the ward of interventional therapy, 7 males and 20 females, aged 47 (27-67), accepted microsurgical operation, The neck, volume, aspect ratio and blood vessel condition of the aneurysms were analyzed.
Results:
The aneurysms difficult to be treated by endovascular interventional therapy included those with wide neck (>4 mm), large volume (maximal diameter>or=8 mm), and failure in endovascular maneuvers (because of flexed blood vessel and severe vasospasm). The total outcome of operation was good and no death occurred.
Conclusion:
Some aneurysms difficult to be treated by endovascular interventional therapy should be treated by microsurgical operation, which will get a better result.
