Abstract Background Intracranial aneurysm(IA) is a serious disease.Analyze and review the cases of anterior circulation ruptured IA by supraorbital lateral keyhole approach, and summarize the experiences of this approach. Methods Retrospective analysis of 16 cases of ruptured anterior circulation IA in our department from January 2019 to June 2020, CT angiography (CTA) was performed before operation. Analyzing the IA’s parameters by 3D-CT reconstruction. The IA was clipped by supraorbital lateral keyhole approach combined with the 3D-skull reconstruction. Extraventricular drainage were performed before craniotomy. Intraoperative neurophysiological monitoring was performed during the operation. After operation, fluorescein angiography and vascular ultrasound were performed to check the clipping effect. Intracranial pressure monitor was performed postoperatively. CTA was reexamined one week after operation. The modified Rankin Scale (MRS) was performed 6 months after operation. Results There were 7 males (43.8%) and 9 females (56.2%) ,the average age is 52.3 years. Among them, 11 patients(68.8%) were anterior communicating artery aneurysms and 5 (31.2%) were middle cerebral artery aneurysms. All patients were out of hospital within 10 days without any death, without cerebral infarction, cerebrospinal fluid leakage and neurological impairments. About mRS score, after 6 months follow-up, 8 cases(50%) had 0 point, 4 cases (25%) had 1 point, 4 cases (25%) had 2 points. Conclusions For ruptured anterior circulation IA, the supraorbital lateral keyhole approach combined with ventricular drainage, intraoperative electrophysiological monitoring and intraoperative vascular ultrasound is a safe and minimally invasive treatment. The application of reconstruction clipping can reconstruct the diameter of parent vessel and reduce the recurrence rate of IA.

Abstract Background Comparative studies between standard pterional and supraorbital keyhole approaches for aneurysms had potential biases with the heterogeneity of patient selection, differences among surgeons, or varying expertise across the surgeon’s learning curve. This is a study of a surgeon’s transition from pterional to keyhole approach for early clipping of selected consecutive ruptured anterior circulation aneurysms. Methods Patients more than 18 years, presenting within 72 hours of ictus, in good clinical grades 1 to 3, no midline shift, with saccular aneurysms less than 25 mm at either communicating segment of internal carotid artery, anterior communicating artery, or middle cerebral artery segment till bifurcation were studied between the last 25 cases of pterional and first 25 cases of the keyhole, for the intraoperative and postoperative surgical outcome parameters. Results There was no significant difference among baseline parameters, including the location of aneurysms across both groups. While only four cases of pterional had an intraoperative ventricular puncture, the lumbar drain was electively inserted in all keyhole patients. The intraoperative parameters, such as a dural tear, adequate parent vessel exposure, temporary clipping, and intraoperative rupture, did not show any significant difference. None had immediate postoperative deficits. While delayed cerebral ischemia and wound complaints were similar in both groups, temporal hollowing and chewing difficulty were significantly more in pterional patients(p = 0.01). Conclusion A surgeon experienced in pterional approach can comfortably and safely shift to the keyhole for early clipping of selected ruptured aneurysms less than 25 mm, with a comparable surgical outcome but better cosmesis and mastication.

Object The aim of this study was to analyze the location, clinical presentation, and morphological characteristics of pediatric aneurysms and the safety, feasibility, and durability of endovascular treatment. Methods The authors conducted a retrospective study of all cases involving patients 18 years old or younger who underwent endovascular treatment for pediatric aneurysms at their institution between July 1998 and July 2010. The clinical presentation, aneurysm location, endovascular management, and treatment outcome were studied. Results During the study period, 23 pediatric patients (mean age 13 years, range 2 months–18 years) were referred to the authors' department and underwent endovascular treatment for aneurysms. The aneurysms were saccular in 6 cases, dissecting in 4, infectious in 5, and giant partially thrombosed lesions in 8. Fourteen of the aneurysms were ruptured, and 9 were unruptured. Thirteen were in the anterior circulation and 10 in the posterior circulation. The most common location in the anterior circulation was the anterior communicating artery; in the posterior circulation, the most common location was the basilar artery. Saccular aneurysms were the most common type in the anterior circulation; and giant partially thrombosed and dissecting aneurysms were the most common types in the posterior circulation. Coil embolization was performed in 7 cases, parent vessel sacrifice in 10, flow reversal in 3, glue embolization in 2, and stent placement in 1. Immediate angiographic cure was seen in 21 (91%) of 23 patients. Complications occurred in 4 patients, 3 of whom eventually had a good outcome. No patient died. Overall, a favorable outcome was seen in 22 (96%) of 23 patients. Follow-up showed stable occlusion of aneurysms in 96% of the patients. Conclusions Pediatric aneurysms are rare. Their clinical presentation varies from intracranial hemorrhage to mass effect. They may also be found incidentally. Among pediatric patients with aneurysms, giant aneurysms are relatively common. Endovascular management is associated with low rates of complications and is a safe, durable, and effective treatment for pediatric aneurysms.

Recurrent aneurysms of the anterior circulation that are distal to the anterior communicating artery (ACoA) but proximal to the callosomarginal–pericallosal bifurcation can pose a treatment challenge. The authors present one such case, in which the patient was treated with pericallosal artery–pericallosal artery (PerA–PerA) side-to-side bypass, followed by endovascular obliteration of the proximal A2 parent vessel. This patient, in whom an ACoA aneurysm had been treated with clip ligation 5 years previously, presented with a new, mid-A2, right-sided aneurysm with the out-flow artery arising from the dome of the lesion. The treatment plan included two steps: an interhemispheric transcallosal approach for PerA–PerA side-to-side anastomosis; and endovascular coil embolization of the right A2 branch feeding the aneurysm. Postprocedure angiography demonstrated no ipsilateral aneurysm filling and excellent bilateral distal outflow from the anterior cerebral artery (ACA). The use of PerA–PerA side-to-side bypass for the treatment of an ACA aneurysm, followed by parent vessel occlusion, offers an elegant solution for the treatment of A2 aneurysms that are not amenable to stand-alone clip ligation or coil occlusion. Such combined methods are invaluable in the management of complex cerebral aneurysms.

Object The purpose of this study was to assess the efficacy and describe the technical features of combined endovascular and microsurgical treatments for complex and giant unruptured intracranial aneurysms. Methods A prospectively maintained database was reviewed to identify all patients with unruptured intracranial aneurysms who were treated with combined techniques. Twenty-one lesions were treated in as many patients: six lesions involved the posterior cerebral artery (PCA); seven the cavernous portion of the internal carotid artery (ICA); two the basilar apex; two the basilar trunk; and one each the anterior communicating artery, anterior cerebral artery, petrous ICA, and cervical ICA. Aneurysms were treated with combined extracranial–intracranial bypass procedures and parent-vessel occlusion, flow redirection, or arterial transposition. Aneurysm occlusion was achieved in 20 patients. In the remaining patient the aneurysm recurred, requiring stent-assisted repeated coil placement. Three patients suffered permanent neurological deficits related to treatment, and three died, two of whom had basilar trunk aneurysms. Conclusions Certain complex aneurysms may be treated optimally by combining endovascular and surgical procedures. A low incidence of complications follows treatment of anterior circulation aneurysms. Treatment of complex posterior circulation aneurysms is associated with a higher incidence of complications, although this likely reflects the more complex nature of these lesions. The risks of this combined treatment strategy are likely lower than the risks associated with the natural history of this subset of 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.

Object. The routine use of intraoperative angiography as an aid in the surgical treatment of aneurysms is uncommon. The advantages of the ability to visualize residual aneurysm or unintended occlusion of parent vessels intraoperatively must be weighed against the complications associated with repeated angiography and prolonged vascular access. The authors reviewed the results of their routine use of intraoperative angiography to determine its safety and efficacy. Methods. Prospectively gathered data from all aneurysm cases treated surgically between January 1996 and June 2000 were reviewed. A total of 303 operations were performed in 284 patients with aneurysms; 24 patients also underwent postoperative angiography. Findings on intraoperative angiographic studies prompted reexploration and clip readjustment in 37 (11%) of the 337 aneurysms clipped. Angiography revealed parent vessel occlusion in 10 cases (3%), residual aneurysm in 22 cases (6.5%), and both residual lesion and parent vessel occlusion in five cases (1.5%). When compared with subsequent postoperative imaging, false-negative results were found on two intraoperative angiograms (8.3%) and a false-positive result was found on one (4.2%). Postoperative angiograms obtained in both false-negative cases revealed residual anterior communicating artery aneurysms. Both of these aneurysms also subsequently rebled, requiring reoperation. In the group that underwent intraoperative angiography, in 303 operations eight patients (2.6%) suffered complications, of which only one was neurological. Conclusions. In the surgical treatment of intracranial aneurysms, the use of routine intraoperative angiography is safe and helpful in a significant number of cases, although it does not replace careful intraoperative inspection of the surgical field.

Abstract OBJECTIVE To describe a novel stent remodeling technique for the coiling of ruptured wide-neck cerebral aneurysms. CLINICAL PRESENTATION A 46-year-old man presented with acute subarachnoid hemorrhage (Hunt and Hess grade IV), intracerebral hemorrhage, and hydrocephalus. Cerebral angiography revealed a wide-neck small anterior communicating artery aneurysm. Conventional coiling was not successful because of coil instability and compromise of the dominant anterior cerebral artery. TECHNIQUE A 6-French shuttle sheath (Cook Medical, Indianapolis, IN) was advanced from a right femoral approach into the right common carotid artery. To protect the parent vessel during coiling without compromising blood flow, a Prowler Select Plus catheter (Cordis Corporation, Bridgewater, NJ) was navigated across the aneurysm neck. Subsequently, an Enterprise stent (22-mm length; Cordis Corporation) was partially deployed across the aneurysm's wide neck. It was very important to watch the distal markers of the stent and lock the stent delivery wire to the Prowler Select Plus with a hemostatic valve once the stent was halfway deployed. This maneuver was essential to prevent further deployment of the stent. The SL-10 microcatheter and Synchro 14 wire (Boston Scientific, Natick, MA) were carefully navigated to the aneurysm passing through the partially deployed stent. Coils were then delivered to the aneurysm using the stent as a scaffold. After coiling, the SL-10 microcatheter was removed and the stent was recaptured into the Prowler Select Plus catheter. During the recapture, there was initial resistance. This was easily overcome after deploying the stent a little more before resheathing. During the procedure, the patient received 2000 U of heparin after the first coil was detached in the aneurysm. CONCLUSION The stent remodeling technique is a novel endovascular technique that can be used to treat ruptured wide-neck aneurysms and maintain patency of parent vessels, avoiding the use of antiplatelet therapy in acute subarachnoid hemorrhage.

Incomplete Occlusion

Flow diverter devices have become a routine first-line option for treatment of an increasing population of intracranial aneurysms at many neurovascular centers.  Despite the promising results of flow diverter stents on anterior circulation, incomplete occlusion on the presence of fetal posterior circulation has been described on several reports.  Here we describe a novel technical alternative to conventional flow diversion approach for this specific subgroup of aneurysms using the low-profile flow diverter, Silk Vista Baby. The device was selectively placed into the fetal type posterior cerebral artery in half-T configuration for the treatment of a posterior communicating aneurysm using a transcirculation approach through the anterior communicating artery. This represents a useful and effective technique and should be considered when encountering the above-described situation.
