AbstractThe occurrence of multiple intracranial aneurysms (MIAs) is not rare, with a reported incidence of 15 to 35%. However, patients harboring seven or more intracranial aneurysms are so uncommon that only sporadic cases have ever been reported. We present a rare case with seven intracranial aneurysms (two anterior communicating artery aneurysms, two right middle cerebral artery aneurysms, two left ophthalmic artery aneurysms, and one right ophthalmic artery aneurysm) in the anterior circulation that were simultaneously clipped via the extended right pterional approach. The surgery was uneventful. The patient experienced a rapid postoperative recovery with no neurologic deficits. To our knowledge, this is the first case of seven bilateral intracranial aneurysms that were surgically clipped via unilateral craniotomy. This case showed that in properly selected patients with anterior circulation MIAs, even as many as seven, one-stage clipping can be achieved. Successful clipping of the contralateral ophthalmic aneurysms was the key step in the operation.

Anterior communicating artery (ACoA) aneurysm, accounts for 30%-35% of all the aneurysm making it one of the most common intracranial aneurysms. Although the Pterional approach is considered as the safe and appropriate method in ACoA aneurysm surgery, temporalis atrophy and injury to a frontal branch of the facial nerve are few inexorable complications. With the advancement of minimally invasive surgery several modified approaches, such as the supraorbital eyebrow incision approach, the minipterional approach, the mini-supraorbital approach, and the lateral supraorbital approach has been recently introduced and has been used as an alternative.

Background and purpose This retrospective study evaluates the safety, effectiveness, and long-term clinical and angiographic follow-up of intracranial aneurysms treated with the Low-Profile Visualized Intraluminal Support Junior (LVIS Jr.) stent and parent vessels of diameter equal to or less than 2.5 mm. Materials and methods We included all patients treated with the LVIS Jr. stent in aneurysms with small parent vessel diameter between March 2015 and July 2017. Periprocedural adverse events, immediate aneurysm occlusion rates, and clinical and angiographic follow-up are reported. Results A total of 35 patients with 35 aneurysms were included. Ten aneurysms were ruptured (28.6%) and 25 were unruptured (71.4%). The parent arteries measured 0.9 mm to 2.5 mm in diameter (mean, 2.2 mm). Intra-procedural thromboembolic complications occurred in four patients (11.4%) and there was an intraoperative aneurysm rupture in one patient (2.8%). Immediate complete aneurysm occlusion was noted in 21 out of 35 patients (60%). Clinical follow-up ranged between one and 25 months (mean, 10.5 months) and magnetic resonance angiography follow-up ranged between four and 24 months (mean, 10.4 months). Complete aneurysm occlusion was achieved in 21 out of 29 patients (72.4%) at last angiographic follow-up (mean, 9.4 months; range four to 23 months). In-stent stenosis occurred in one out of 29 patients (3.4%), who was asymptomatic. Of the four patients with in-stent thrombosis, three patients were treated with “Y configuration” (two patients with middle cerebral artery aneurysms and one patient with an anterior communicating artery aneurysm). Mortality rate was 0%. Neurological morbidity was 2.9%. Conclusions Stenting with the LVIS Jr. stent allowed us to treat complex intracranial aneurysms with parent vessel diameter of 2.5 mm or less with an acceptable safety profile.

Introduction: Rupture of intracranial aneurysms is the most common cause for spontaneous subarachnoid hemorrhage. It is a devastating stroke with high morbidity and mortality. This study was done to determine the frequency, location and size of aneurysms in patients presenting with spontaneous subarachnoid hemorrhage.Methods: This prospective cross sectional observational study was conducted in the Neurosurgery Unit of Manipal Teaching Hospital from January 2012 to June 2016. All patients who presented with spontaneous subarachnoid hemorrhage and had a positive angiography of brain were included in the study.Results: There were 39 patients who had positive angiographic results. Male: female ratio was 1:2.25. Mean age was 55.79 years. Nine patients had more than one aneurysms. More than 50% of patients were of age group 50-70 years. Anterior circulation aneurysms were found in 90% of patients. Anterior communicating artery was the commonest location of aneurysms. Most of the aneurysms had neck size less than 4 mm.Conclusion: Anterior communicating artery aneurysm was the commonest location of ruptured aneurysms.  23.07% of patients had multiple aneurysms.

Abstract Background: The anterior communicating artery (AcoA) aneurysm is one of the most challenging aneurysms. As endovascular techniques evolve, a remaining challenge is the reduction of complications related to the surgical approach. Although the endonasal approach is widely used for pituitary adenomas and is increasingly popular for suprasellar tumors, only 2 aneurysm cases have been reported. Objective: To the best of our knowledge, we are reporting the first case of successful endoscopic endonasal clipping of an unruptured ACoA aneurysm. Methods: An ACoA aneurysm was discovered in a 55-year-old man before he was to undergo an endoscopic biopsy of an orbital lesion. Because of the operative corridor formed during this first operation and ideal conformation of the aneurysm for this line of sight, we formulated an endoscopic route for this ACoA aneurysm. Results: An endoscopic endonasal transplanum-transtuberculum approach was performed. Proximal and distal control was obtained, and the AcoA aneurysm was successfully clipped. The postoperative course was uneventful with a rapid recovery. Conclusion: On the road of innovation in the treatment of intracranial aneurysms, the endoscopic approach provided another option whose value must be weighed in terms not only of feasibility but in the patient’s best interest. We caution extreme prudence if considering this procedure as an alternative to well-established techniques. Yet its upward route offers limited retraction for deep-seated lesions. Rapid progress of endoscopic techniques may prove promising for well-selected cases of ACoA aneurysms.

Abstract OBJECTIVE This study investigated olfactory dysfunction after using a contralateral or ipsilateral pterional approach for anterior circulation aneurysms and related risk factors. METHODS This study included 189 patients who experienced an aneurysmal subarachnoid hemorrhage and in whom a pterional approach was used, including a contralateral pterional approach (12 patients), a pterional approach for an anterior communicating artery (AComA) aneurysm (70 patients), and an ipsilateral pterional approach for aneurysms of the anterior circulation, excluding the AComA (107 patients). In addition to questionnaires on olfactory function, Sniffin' Sticks tests were performed 12 to 38 months after the operation. RESULTS The incidence of olfactory dysfunction was high: 58% (7 of 12) with a contralateral pterional approach, 14% (10 of 70) with a pterional approach for an AComA aneurysm, and 4% (4 of 107) with an ipsilateral pterional approach for aneurysms of the anterior circulation, except for the AComA. In addition, patients 55 years and older had a higher incidence of olfactory dysfunction. Among the 12 patients in whom the contralateral pterional approach was used, 5 (42%) were anosmic and 2 (17%) were hyposmic. The incidence of olfactory dysfunction was also significantly higher at ages 55 years and older. The size and location of the contralateral aneurysm, if small (<1 cm) and located within a 3-cm lateral distance from the midline, were not found to influence the incidence. CONCLUSION A higher incidence of olfactory dysfunction was found in those patients in whom a contralateral pterional approach and a pterional approach for an AComA aneurysm were used. Another major risk factor was an age of 55 years and older.

✓The combination of surgical and endovascular treatment for complex intracranial aneurysms has previously been used in a staged fashion. To perfect the clipping process of a complex anterior communicating artery aneurysm and to avoid a second staged procedure, the authors used a method of direct intraoperative transaneurysmal coil-assisted clip occlusion of the aneurysm. To the authors' knowledge this is the first time direct intraoperative transaneurysmal coil-assisted clip occlusion has been reported. It should be kept in mind as one of the options to help in complete obliteration of complex intracranial aneurysms.

ABSTRACT BACKGROUND AND IMPORTANCE The Coupler microanastomotic device (Medical Companies Alliance, Birmingham, Alabama) aims at facilitating safe and efficient end-to-end reconstruction of the native vessel ends following resection of intracranial aneurysms. CLINICAL PRESENTATION We report the first case of the Coupler device used to treat a ruptured posterior inferior cerebellar artery (PICA) aneurysm. Following aneurysmal trapping and excision, the native parent vessel ends were connected in an end-to-end fashion. CONCLUSION The microanastomotic Coupler device is an acceptable option for end-to-end anastomosis and was successfully applied in the management of a ruptured fusiform PICA aneurysm.

BackgroundWoven EndoBridge (WEB) deployment remains challenging in aneurysms with a complex shape or orientation.ObjectiveTo show that embolization of wide-neck bifurcation aneurysms using the WEB device balloon remodeling-assisted technique is a feasible and elegant endovascular solution compared with other techniques, such as balloon remodeling or stent-assisted coiling.Materials and methods10 cases (10 aneurysms in 9 patients) of balloon remodeling-assisted WEB treatment of unruptured complex bifurcation aneurysms were treated in our institution and retrospectively analyzed. Details of clinical presentations, technical details, perioperative and postoperative complications, and outcomes were collected. Immediate and long-term angiographic results were also evaluated.ResultsAneurysms included six middle cerebral artery aneurysms, one anterior communicating artery aneurysm, one posterior communicating artery aneurysm, one basilar artery aneurysm, and one T-shaped carotid aneurysm. Mean dome width was 6.55 mm, mean neck size 4.5 mm, mean height 4.79 mm, and mean dome-to-neck ratio was 1:1.46. Treatment was performed exclusively with the balloon remodeling-assisted WEB technique in all cases. The device was successfully deployed in every case. Periprocedural thromboembolic or hemorrhagic events did not occur. The modified Rankin Scale score at discharge was 0 for all patients. At mid-term or long-term angiographic follow-up, adequate occlusion was observed in 7 aneurysms from 8 controlled cases (87.5%), and one patient (2 aneurysms) did not have angiographic follow-up.ConclusionThe balloon remodeling-assisted WEB technique seems to be a safe and effective solution for endovascular treatment of unruptured wide-neck bifurcation aneurysms with specific complex anatomy. However, further studies are needed to evaluate the rate of complications and long-term efficacy.

Skull base approaches play a fundamental role in modern neurosurgery by reducing surgical morbidity. Increasing experience has allowed surgeons to perform minimally invasive approaches without straying from the premises of skull base surgery. The eyelid approach has evolved from the orbitopterional osteotomy into a more effective and targeted approach to disease of the anterior cranial fossa. In this technique, after an incision is made on the supratarsal fold, the orbicularis oculi muscle is incised, and a myocutaneous flap composed of the elements of the anterior lamella is elevated. Subperiosteal dissection is used to expose the superior and lateral walls of the orbit, the superior and lateral orbital rim, and the frontosphenoidal suture. A MacCarty bur hole is drilled, and a frontal osteotomy is fashioned medial to the supraorbital notch and extending through the orbital roof back toward the orbital half of the MacCarty bur hole, exposing the frontobasal brain. A conventional microsurgical technique is used to treat tumors and aneurysms of the anterior cranial fossa under the operative microscope. Five patients were treated for unruptured aneurysms of the anterior circulation (3 anterior communicating artery aneurysms, 1 ophthalmic artery aneurysm, and 1 posterior communicating artery aneurysm) using the eyelid approach. The mean aneurysm size was 5 mm, and all aneurysms were approached from the right side. Three tumors in the anterior fossa (2 suprasellar pituitary adenomas and 1 craniopharyngioma) were also excised using this approach. There was no surgical morbidity. Three months after surgery all patients presented excellent cosmetic results. The eyelid approach may be considered as an effective, cosmetically beneficial, and minimally invasive skull base approach to selected aneurysms and tumors of the anterior circulation.
