[Postoperative transient occlusion of internal carotid artery due to shift of the clip used for neck clipping of the huge left internal carotid aneurysm (author's transl)].
A 49-year-old female, having had suffered from a huge left internal carotid (IC) aneurysm and a right IC aneurysm, was treated surgically. The neck of huge aneurysm, was treated surgically. The neck of huge aneurysm was clipped with Sugita's spring clip after its body was dissected and the otherone was clipped simply. Right hemiparesis was seen postoperatively. And the angiograms, taken on the 4th postoperative day, showed not only an aneurysmal disappearance but also an occlusion of the left ICA which presumably due to shift of the spring clip to the direction of antero-lateral. Right hemiparesis disappeared, however, suddenly on the 40th postoperative day and reopening of the left ICA was confirmed angiographically despite the further shift of the clip. The possible genesis of the curious course in this case and the possible complications in the use of large aneurysmal clip was discussed.
