AbstractIntraoperative rupture is the most important complication of aneurysm surgery1-5 and occurs in 3 different stages: premature (before dissection), dissection, and clipping.5 We present a video of premature rupture and its management (Video 1). A 45-year-old patient presented with subarachnoid hemorrhage originating from a dorsal internal carotid artery (ICA) aneurysm of the communicating segment. Due to our sufficient experience, we preferred direct clipping in this case. The Sylvian fissure could only be partially opened due to excessive adhesions. During retraction of the frontal lobe, severe bleeding occurred. This was a premature rupture since neither the aneurysm nor the ICA had yet been seen. While aspirating the bleeding just over the rupture site with the left hand, the ICA was explored with the right hand and a temporary clip was placed. The bleeding continued, though it decreased. The aneurysm dome was rapidly explored with 1 hand, and a pilot clip was placed on the dome to stop the bleeding. Immediately afterwards, the aneurysm neck was dissected and clipped parallel to the ICA with a sideward clip. The temporary clip and pilot clip were removed. The temporary occlusion time was 7 minutes and 40 seconds. Postoperative angiogram confirmed complete aneurysm occlusion. The patient discharged with normal neurologic examination. In the literature review including 10,540 cases,1 the mean incidence of IOR is 16.6%. Therefore every neurosurgeon should be prepared for this important complication and know its management well. This case reminds us once again the golden rule of aneurysm surgery: proximal control first.Copyright © 2023 Elsevier Inc. All rights reserved.
