Abstract
Giant intracranial aneurysms represent a very challenging aspect of aneurysmal pathophysiology with very high mortality and morbidity if left untreated. Their variety in clinical presentation (subarachnoid hemorrhage, cranial nerve palsy, etc.) and pathological and imaging properties (location, anatomy, presence of collateral circulation) pose serious questions regarding the best treatment option. Admirable advances have been achieved in surgical techniques, while endovascular modalities with flow diversion techniques have become widely used. However, there is still lack of data regarding whether a single endovascular technique can be the universal treatment for such cases. In this review, we aim to summarize the current funds of knowledge concerning giant intracranial aneurysms and the role of endovascular management in their treatment.

Microsurgical treatment of ophthalmic artery aneurysm, a case series of 55 patients with long-term follow-up. BMC Surg 2024; 24:139. [PMID: 38714953 PMCID: PMC11075342 DOI: 10.1186/s12893-024-02419-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 04/18/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Ophthalmic artery aneurysm (OAA) can be secured in endovascular or microsurgical approaches. Still there are controversies in technique selection and their long term outcomes. METHODS All the patients with OAA were treated microsurgically and followed. Demographic data, neurological status, physical examination findings, angiographic data, operation details, and intraoperative and postoperative events were recorded and analyzed. P < 0.05 was considered significant. RESULTS Among 55 patients, 38 were females (69.1%). Median preoperative glasgow coma scale (GCS), Fisher Grade, and Hunt and Hess(HH) scores were 15, 1 and 1, respectively. The most common neurologic manifestation was visual problems (n = 15). The most common anatomical projection was medial (43.6%) oriented lesions. 85.5% of them only had 1 ophthalmic aneurysm while multiple aneurysms were reported in 14.6%. In 52 patients temporary clip was used. in 21 patients (38.2%) intraoperative aneurysm rupture occurred. Larger aneurysm size and preoperative hydrocephalus were associated with higher rates of aneurysm rupture (P = 0.003 and 0.031). 28.5% of the patients with visual problems had clinical improvement in the postoperative period. The mean follow-up period was 5 years. Follow-up angiography showed a 100% obliteration rate with a 0.0% recurrence rate. Median values for follow-up glasgow outcome scale and modified Rankin scale were 5 and 0, respectively. favorable neurological outcomes were associated with better primary GCS and HH scores. CONCLUSION OAA microsurgery is an effective and safe procedure with significant improvement in both visual and neurological status. Low recurrence rate and excellent clinical recovery are the most important advantages of microsurgery in OAA treatment.

Abstract
In the surgical treatment of cerebral vascular malformations, e.g., aneurysms and arteriovenous malformations, the risk of ischemic complications is 6.7%, and a residual aneurysm is possible in 5.2% of these cases. Ischemic lesions can result in permanent neurological deficits, and a residual aneurysm can lead to the recurrence of the aneurysm in 2% of cases. In this article, we present five cases (two cases of ruptured aneurysms, two cases of non-ruptured aneurysms, and a case of arteriovenous malformation) in which we reduced the aforementioned risks with the use of intraoperative neuromonitoring and angiography. Intraoperative neuromonitoring (IONM) is used to measure motor and sensory-evoked potentials to detect brain hypoperfusion. Intraoperative angiography with the dye indocyanine green (ICG-A), which fluoresces in a vessel under a microscope after intravenous administration, helps to identify residual aneurysm sacs and distal blood flow. With the use of IONM and ICG-A, we identified abnormalities and adjusted our interventions and treatments. IONM and ICG-A can lead to a better outcome after surgical treatment of cerebral vascular abnormalities.

Abstract
Background Aneurysm surgery is considered difficult by young and trainee neurosurgeons. This is due to difficulty in understanding orientation of aneurysm complex (proximal and distal vessels, aneurysm neck, and fundus) in relation to the surrounding structures (skull, brain, vessels, and nerves) after head is rotated, extended, and fixed on the head frame. Virtual three-dimensional (3D) imaging studies and 3D-printed models help young neurosurgeons but are not accessible to most of the centers due to need for resources (human and equipment). Authors used handmade 3D models of aneurysm complex to train young neurosurgeons before and during surgery to make them understand steps to treat it. Methods RadiAnt DICOM viewer software (2022.1.1, 64-bit, Medixant, Poznan, Poland) was used for acquiring 3D Volume Rendering Technique images to make aneurysm models preoperatively. Twisted 20 Gauze galvanized iron wires were used for making proximal and distal branches and Epoxy Putty (M-seal, Pidilite ® industries, Mumbai, India) was used to make smooth surfaces of the vessels, aneurysm necks, and fundi. Models were used in operating room (OR) before and during surgery to help surgeons and trainees get oriented to the aneurysm complexes. Results Handmade models, oriented as per patients' head position, were useful to make surgeons and trainees to understand projection of various components of the aneurysm complex in relation to adjacent structures, especially skull base, during both preoperative planning and in OR even before completion of the dissection. Conclusion Handmade models of aneurysms are inexpensive tool and can help trainee neurosurgeons to plan and execute surgical management of aneurysms.

Analysis of the Surgical Outcome of Unruptured Intracranial Saccular Aneurysms in Octogenarians (80-89 Years). Asian J Neurosurg 2020; 15:640-643. [PMID: 33145219 PMCID: PMC7591182 DOI: 10.4103/ajns.ajns_44_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 04/07/2020] [Accepted: 04/25/2020] [Indexed: 11/28/2022] Open
Abstract
Background: The prevalence of unruptured intracranial aneurysms is increasing in elderly population in Japan. Octogenarians (80–89 years) are more prone to complications due to increased age, comorbidities, increased risk of vasospasm, and treatment risks. Aim: The aim is to study the surgical outcome of unruptured intracranial saccular aneurysms in elderly patients aged between 80 and 89 years. Patients and Methods: A retrospective study was conducted involving all the cases of unruptured intracranial saccular aneurysms operated surgically in elderly patients aged between 80 and 89 years. All the cases operated between January 2017 and October 2019 were included in the study. The preoperative neurological status was assessed using the Glasgow Coma Scale (GCS). The comorbidities and risk factors involved were assessed. Postoperative neurological status was assessed by (1) postoperative GCS score and by the (2) presence or absence of the motor weakness of limbs. Results: Thirty-three aneurysms were operated in 27 patients. Two patients were operated two times at separate occasions for different aneurysms during the study period and hence making a total of 29 surgeries. The age range was 80–88 years, with a mean of 82.4 years ± 2.64 standard deviation (SD). There were 7 (24.1%) males and 22 (75.86%) females. All the patients had a preoperative GCS score of 15/15 without focal neurological deficit. The mean size (mm) of the aneurysms was 6.57 ± 4.04 SD. There were 31 (93.94%) aneurysms in the anterior circulation and 2 (6.06%) aneurysms in the posterior circulation. The comorbidities and risk factors were analyzed and found to be not influencing the outcome of the patients. Clipping was done in 32 aneurysms. One case of posterior inferior cerebellar artery (PICA) aneurysm underwent occipital artery to PICA bypass surgery. The postoperative complications include chronic subdural hematoma (CSDH) in 7 (24.13%) patients, extradural hematoma in 1 (3.4%), meningitis in 1 (3.4%), and lower cranial nerve palsy in 1 (3.4%) patient. All the patients were discharged with GCS score 15/15 without motor weakness of the limbs. The mean duration of stay was 16.62 days ± 9.98 SD. Conclusion: Surgery for unruptured saccular aneurysms in octogenarians has got a good result in the tertiary care facility. Advanced age alone should not be considered for preferring coiling over clipping. Octogenarians are more prone to developing postoperative CSDH.
