[Microsurgical techniques for dorsal wall aneurysms 
in the internal carotid artery]

To seek a reasonable microsurgical technique for dorsal wall aneurysms in the internal carotid artery (ICA), and to evaluate its efficacy.
 Methods: A total of 21 patients with dorsal wall aneurysms in the ICA who received microsurgical techniques were retrospectively analyzed. The directive surgical clapping was applied for saccular aneurysm, while the techniques of stitching and wrapping, simple wrapping, and trapping with extracranial-intracranial bypass were used for cystic and blood blister false aneurysms.
 Results: One patient died after operation, 1 patient suffered rebleeding and gave up treatment, the remaining 19 patients achieved saticfactory outcomes.
 Conclusion: According to types of aneurysm wall, the different microsurgical treatments should be applied, and good outcomes can be achieved for patients with dorsal wall aneurysms in the ICA.
