A clinical evaluation of the merits of titanium clips for cerebral aneurysms: Results in the postoperative MRI and CT images of twenty-six repaired aneurysms

The newly developed Yasargil titanium clips for cerebral aneurysms (AESCULAP Co.) are claimed to reduce the number of artifacts on postoperative CT and MRI assessments. To confirm the merits of such clips, new Yasargil titanium aneurysm clips were clinically investigated in situ as seen on using an 1.5T MR imager. These titanium clips appeared to cause far fewer clip induced MR and CT artifacts than did phynox and elgiloy aneurysm clips. Further, no titanium clip movement was seen after placement in the MR images. Based on these experimental findings, titanium clips were used to repair 26 cerebral aneurysms. Postoperative CTs, particularly. Helical CT scannings, and MRIs showed very few artifacts in the images of all patients. It thus has been concluded that titanium aneurysm clips are better than other types of aneurysm clips for postoperative imaging evaluations of the patient's neurological status.
