    Abstract:
    OBJECTIVE: Surgical treatment of an intracavernous carotid aneurysm (ICCA) is difficult because of the close relationship to bone, dura, and neurovascular structures. Intraoperative rupture of an ICCA is challenging, especially if the site of rupture is at the base of the aneurysm. We present a case of intraoperative rupture of an ICCA caused by clinoidectomy. We repaired it by using a single-clamp applicator (AnastoClip Vessel Closure System, 1.4 mm; LeMaitre Vascular, Burlington, MA). CLINICAL PRESENTATION: In April 2007, a 40-year-old woman underwent neurosurgical treatment at another institution for a ruptured basilar bifurcation aneurysm, with good recovery. Digital subtraction angiography performed at this time showed the presence of left internal carotid artery aneurysms, 1 at the anterior wall of the paraclinoidal segment and 1 at the lateral wall of the intracavernous segment. In February 2008, the patient was referred from outside Finland to our department for microsurgical treatment of both aneurysms. TECHNIQUE: A lateral supraorbital approach was used, and during extradural removal of the anterior clinoid with a rongeur, the ICCA ruptured. The base of the intracavernous aneurysm was involved in the rupture, and we used a single-clamp applicator to repair the internal carotid artery. Intraoperative digital subtraction angiography, indocyanine green video angiography, and Doppler ultrasonography showed a good flow in the artery. The paraclinoid aneurysm was uneventfully clipped during the same intervention. CONCLUSION: Intraoperative rupture of ICCA was repaired quickly and effectively by using a single-clamp applicator. Our case and experimental data from other microsurgical vascular experiences suggest that the future of intracranial vessel repair/anastomoses will be using microclips and other simpler devices more, allowing the neurosurgeon to perform fast and effective vessel repair.
