摘要
OBJECTIVE Recurrences after complete surgical clipping of an aneurysm base are rare. We describe a potential reason for such recurrences: the inappropriate application of a popular aneurysm clip. CLINICAL PRESENTATION We present 3 cases in which intraoperative indocyanine green video angiography after clipping clearly demonstrates filling of the aneurysm. INTERVENTION During surgery, the necks of the aneurysms were clipped with Yaşargil aneurysm clips (Aesculap AG & Co., Tuttlingen, Germany) without any problems; however, indocyanine green video angiography after clipping showed filling of the aneurysms through the point located at the junction of the blade and spring portions of the clips. In the first patient, the aneurysm sac was further coagulated, and a second, smaller clip was applied to completely occlude the untreated part. In the second patient, the clip was replaced with a different clip that had longer blades. In the third patient, 2 additional clips were applied, and the aneurysm sac was also coagulated. The postoperative computed tomographic angiographic examinations showed total occlusion of the aneurysms and patency of the parent arteries. All patients achieved full recovery after the operations. CONCLUSION We present here, for the first time, evidence that the small orifice located at the junction of the blade and spring portions of Yaşargil aneurysm clips can lead to failure of initial surgery and/or recurrence. This can be avoided by using clips with slightly longer blades to keep the orifice away from the aneurysm or by applying a second clip to occlude the untreated part.
