The authors report a rare case of sequentially developed bilateral internal carotid artery (ICA) fusiform giant aneurysms in a patient with pathologically confirmed intimal fibroplasia. Both ICA fusiform aneurysms were treated with multiple flow diverter insertion and were well-managed over the past 5.5 years of follow-up. The development of aneurysms in this rare disease entity appears to be a lifelong process based on the authors’ observations in serial angiographic follow-up studies. Reconstruction therapy using flow-diverting stents in this unique condition may be a safe and effective treatment modality.

Introduction The treatment of aneurysms in the internal carotid bifurcation region (ICABR), including aneurysms of the true internal carotid artery (ICA) terminus, those inclined on the proximal A1 or M1 segments or at the most distal pre-bifurcation (ICA) segment, is often challenging in microsurgical clipping and endovascular surgery. Few reports had discussed flow diversion as a therapeutic option for this group. Methods This was a retrospective study analysing flow diversion in treating ICABR aneurysms. Seven patients harbouring eight aneurysms in the ICABR were treated with flow diversion. Five aneurysms were inclined on the proximal A1 segment, and three were located at the most distal pre-bifurcation segment. Patients’ demographics, presentation, procedure technical description, angiographic and clinical follow-up were recorded. PubMed and Ovid MEDLINE were also reviewed for articles published in English, including case series or case reports, for ICABR aneurysms treated with flow diverters. Results All patients except one underwent angiographic follow-up. The Karman–Byrne occlusion scale was used to determine the occlusion rate. All six patients with documented angiographic follow-up had a class IV occlusion score. No permanent or transient neurological or non-neurological complications were encountered in this study. Conclusion Treating ICABR aneurysms using flow diversion is feasible, with a promising angiographic occlusion rate. Further studies are needed to analyse long-term clinical and angiographic results.

✓ Five cases of a congenital berry aneurysm of the internal carotid artery with origin partially intradural and fundus mainly intracavernous are presented. Angiography does not allow a precise definition of the amount of aneurysm that is intradural, a fact of importance when planning treatment of these cases. However, the angiographic features are characteristic of the type and suggest that these aneurysms be grouped together as a separate entity.

Object The ophthalmic artery (OphA) usually arises from the intradural internal carotid artery (ICA), and the extradural origin has also been known. However, the interdural origin is extremely rare. The purpose of this paper was to clarify the origin of the OphA in patients with a paraclinoid aneurysm in the ICA based on intraoperative findings. Methods The authors retrospectively examined 156 patients who underwent direct surgical treatment for 166 paraclinoid aneurysms during a 17-year period. Based on intraoperative findings, 119 ophthalmic arteries were analyzed with respect to their origins. Results The OphA originated from the intradural ICA on 102 sides (85.7%), extradural on 9 (7.6%), and interdural on 8 (6.7%). Although the extradural origin might be recognized preoperatively, it was difficult to distinguish the interdural origin of the OphA from the intradural one. Conclusions The incidence of the interdural origin was 6.7% and was not as rare as the authors expected. Neurosurgeons should know the possible existence of the interdural origin of the OphA to section the medial side of the dural ring.

Aneurysms of the internal carotid artery are the second most common among cerebral aneurysms. When an aneurysm is located in the ophthalmic segment of the internal carotid artery (ICA), the intravascular treatment method is a priority. At the same time, the treatment of recurrent and non-radially switched-off aneurysms of this localization remains a subject of discussion.Case report. We present a 42-year-old patient with a ruptured ICA aneurysm who was admitted in a serious condition. Initially, the patient underwent partial occlusion of the aneurysm cavity with endovascular coiling. In the control cerebral angiography 3 months after the haemorrhage, the recanalization of the aneurysm was verified, which served as an indication for repeated surgical intervention. We preferred the microsurgical method of treatment. A control angiographic study 1 year after the second operation confirmed the radical shutdown of the aneurysm.Discussion. The presented case illustrates the need for a flexible approach in the treatment of complex paraclinoid aneurysms. The choice of endovascular treatment of such aneurysms in the acute period of haemorrhage is justified as the most sparing, although less radical. Depending on the nature of the embolization performed, the timing of the control angiographic examination should be selected individually and can be reduced to 2 months. If there are indications for repeated surgical intervention, it should be performed by the safest method, providing total shutdown of the aneurysm and reducing the volumetric impact of the aneurysm dome on the optic nerve.

Abstract BACKGROUND: Unruptured aneurysms of the cavernous and paraclinoid internal carotid artery can be approached via microsurgical and endovascular approaches. Trends in treatment reflect a steady shift toward endovascular techniques. OBJECTIVE: To analyze our results with multimodal treatment. METHODS: We reviewed patients with unruptured cavernous and paraclinoid internal carotid artery aneurysms proximal to the posterior communicating artery treated at a single center from 2007 to 2012. Treatment included 4 groups: (1) stent-assisted coiling, (2) pipeline endovascular device (PED) flow diverter, (3) clipping, and (4) trapping/bypass. Follow-up was 2 to 60 months. RESULTS: The 109 aneurysms in 102 patients were studied with the following treatment groupings: 41 were done with stent-assisted coiling, 24 with Pipeline endovascular device, 24 by microsurgical clipping, and 20 by trap/bypass. Group: (1) two percent had delayed significant intraparenchymal hemorrhage; (2) thirteen percent had central nerve palsies, 8% had small asymptomatic infarcts, and 4% had small, asymptomatic remote-site hemorrhages; (3) twenty-nine percent of patients suffered from transient central nerve palsies, 4% experienced major stroke, and 8% had small intracerebral hemorrhages; (4) thirty-five percent had transient central nerve palsies, 10% had strokes, and 10% had intracerebral hemorrhages. In terms of follow-up obliteration, 83% had complete/nearly complete obliteration at last follow-up, 17% had residual aneurysms, and 10% required retreatment. Ninety-six percent of group 1 (35/38), 100% of group 2 (23/23), 100% of group 3 (21/21), and 95% of group 4 had modified Rankin Scale scores of 0 to 1. CONCLUSION: Treatment of these aneurysms can be carried out with acceptable rates of morbidity. Careful patient selection is crucial for optimal outcome. Endovascular treatment volumes likely will continue to predominate over microsurgical techniques as changing skill sets evolve in neurosurgery, but individualized application of all available treatment options will continue.

Abstract Objective: Several different methodologies for proximal occlusion and retrograde suction decompression of large paraclinoid aneurysms have been reported previously. In this article, we describe the novel use of an endovascular embolectomy device (F.A.S.T. funnel catheter; Genesis Medical Interventional, Inc., Redwood City, CA) for temporary internal carotid artery occlusion and suction decompression of an intracranial aneurysm to facilitate surgical clip ligation. The combination of atraumatic occlusion technology and large lumen size makes this technique safer and easier. Clinical Presentation: A 53-year-old woman with progressive headaches underwent computed tomographic angiography, which revealed an unruptured large left paraclinoid aneurysm. Cerebral angiography confirmed the diagnosis. The patient did not tolerate a balloon test occlusion for therapeutic Hunterian internal carotid occlusion. The patient was subsequently taken to the operating room for a craniotomy and clip ligation of the aneurysm. Intervention: A standard left pterional craniotomy was performed with opening of the sylvian fissure and exposure of the left paraclinoid aneurysm. Intraoperative angiography with introduction of a new endovascular embolectomy device was performed. The device was deployed to achieve temporary occlusion of the cervical internal carotid artery, and aspiration through the central lumen allowed for retrograde suction decompression of the aneurysm. Collapse of the aneurysm through this technique permitted visualization of the aneurysmal neck with successful clip ligation. Conclusion: A new endovascular embolectomy device can be used to safely perform suction decompression of large paraclinoid aneurysms to facilitate clip ligation.

Abstract OBJECTIVE To determine whether the use of a specific shape and a navigating method of microcatheters are suitable for placement at paraclinoid aneurysms. METHODS The clinical data from 122 patients with 132 paraclinoid aneurysms that underwent endovascular treatments during a 2.5-year period were retrospectively reviewed. Microcatheter shapes were classified as “straight,” “primary curves” (45, 90, and J), “preshaped-C,” “pigtail” (simple, right, and left), and “S” (simple, right, left, and preshaped). The navigating methods were classified as antegrade/retrograde microcatheter shift, wire-steering, looping, and coil/wire guiding. The shapes and navigating methods were compared among 3 aneurysm groups, which were categorized as superior, medial, and other, based on direction. RESULTS Shapes were significantly different between the 3 groups; the most commonly engaged shape in the superior group, medial group, and other group was S (55%), pigtail (60%), and primary (56%), respectively. The straight and S shapes were used in 5 (83%) and 18 (86%) cases, respectively, in the superior group, whereas the pigtail shape was used in 50 (86%) cases in the medial group. Aside from pigtail-simple shape, the side of pigtail, right vs left, coincided with the side of the internal carotid artery involved in every case of the medial group. The navigating methods were not significantly different among the 3 groups. CONCLUSION A specific shape by paraclinoid aneurysm direction tends to be suitable for the first trial of microcatheter shapes. Operators may reduce unnecessary struggling time of intra-aneurysmal placement of microcatheters by practicing the use of that shape.
