Abstract Objective: Few prospective randomized controlled studies have investigated the efficacy of endovascular treatment and microsurgical clipping of intracranial aneurysms, especially via microsurgical keyhole approach. We compared the efficacy of three techniques in treating patients with ruptured anterior circulation aneurysms to provide surgeons with a more objective basis for treatment selection. Methods: 150 patients with ruptured anterior circulation aneurysms were randomly assigned to endovascular treatment, conventional craniotomy, and keyhole approach groups. Aneurysm occlusion, surgical time, hospitalization time, hospitalization expenses, and surgical complications were compared between groups. Results: The complete occlusion rates of aneurysms at discharge were 90% in the endovascular group, 94% in the conventional group, and 96% in the keyhole group. No significant differences in complete occlusion rates or Glasgow Outcome Scale scores were found between groups. In the keyhole approach, conventional craniotomy, and endovascular groups, the overall surgical times were 161.78±34.51 min, 201.55±38.79 min, and 85.86±58.57 min, respectively; the hospitalization times were 11.42±6.64 d, 18.03±7.14 d, and 10.57±8.67 d; hospitalization expenses were 10574.25±4154.25 USD, 13214.54±5487.65 USD, and 20134.58±6587.61 USD; and the incidence rates of postoperative complications such as intracranial infection, cerebral vasospasm, hydrocephalus, intracranial hematoma, and epilepsy were 8%, 28%, and 20%. Conclusions: Endovascular coiling and the microsurgical keyhole approach have the advantages of simple execution, time savings, and short hospitalization. Microsurgical clipping of intracranial aneurysms needs to be updated to a minimally invasive procedure to maintain its complementary value with endovascular treatment.Clinical trial registration: The study has been retrospectively registered in clinicaltrial.org (NCT05049564) in Sep. 8th, 2021.

Aneurysm Coiling

The purpose of the current study was to examine the reasons for failed endovascular aneurysm coiling and to determine the outcome of immediate microsurgical clipping. From July 2006 to July 2008, 198 patients underwent endovascular coiling at our institute; among them, ten cases were unsuccessful. All of the patients were diagnosed with intracranial aneurysms (ICAs) by cranial computed tomography angiography (CTA), and all underwent endovascular treatment without digital subtraction angiography (DSA). When endovascular coiling failed, the patients were immediately transferred to the operating room for microsurgical clipping under the same anesthetic. The ten patients were divided into three groups based on the cause of endovascular failure and associated clinical features. The clinical follow-up period was between 6–12 months, and all 10 patients had good outcomes following the surgery. Taken together, the results of this study suggest that immediate microsurgical clipping after failed endovascular coiling is efficient and may provide improved outcomes by preventing rebleeding.

AbstractFlow diverter stents (FDS) are new neuroendovascular tools able to achieve the complete and curative treatment of aneurysm by reconstruction of the parent arteries from which the aneurysm arises. We present our initial experience with flow diverter embolization devices and follow-up results.Patients with large, giant and wide necked aneurysms, saccular, fusiform and recurrent aneurysms were selected for the treatment. All patients were pretreated with dual antiplatelet agents at least for 7 days before procedure and continued taking both agents for 3 months after treatment. A MRI was done after 3 months of treatment and digital subtraction angiogram was performed at 4 months of treatment. After 1 year both MRI and digital subtraction angiogram was performed.11 patients (age range 37 year to 79 year, mean 51.1) with 11 intracranial aneurysms were treated with 15 flow diverter stents. 9 aneurysm were located on the anterior circulation and 2 on posterior circulation. 8 aneurysms were large (10-25 mm), 2 were small (<10 mm) and 1 was giant (>25 mm) with mean largest diameter of 13.22 mm. 9 were saccular aneurysm and 2 were fusiform, out of these 3 were remnant of the previously treated aneurysm. Treatment was achieved with 10 Silk stents in 7 patients and 5 Pipeline embolization devices in 4 patients. The mean time between treatment and follow up was 9.6 months (range 4-12 months). One mortality was noted due to rebleed after 3 weeks of treatment. Complete angiographic occlusion was achieved in 9 (90%) patients after 4 months and 1 (10%) patient had near complete occlusion at 12 months. All the patients were stable clinically during follow up period.Endovascular treatment with FDS is safe, easy, and permanent treatment for the selected group of aneurysms. The complete occlusion rate in follow-up study approaches 100% with no angiographic recurrence in this study.

Anterior Circulation Aneurysms

Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence of 10.5 / 100000 person/year, varying in individual reports from 1.1 to 96 /100000 person/year. Angiographic and autopsy studies suggest that between 0.5% and 5% of the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal subarachnoid hemorrhage in the United States each year, and 60% die or are left permanently disabled. We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January 1997 to January 2003. Four hundred and seventy-seven patients were submitted to 525 craniotomies for treatment of 630 intracranial aneurysms. The majority of patients were female (72.1%) in the fourth or fifth decade of life. Anterior circulation aneurysms were more common (94.4%). The most common location for the aneurysm was the middle cerebral artery bifurcation. The patients were followed by a period from 1 month to 5 years. The outcome was measured by the Glasgow Outcome Scale (GOS). At discharge, 62.1% of the patients were classified as GOS 5, 13.9% as GOS 4, 8.7% as GOS 3, 1.7% as GOS 2 and 14.8% as GOS 1.

Anterior Circulation Aneurysms

Options for treatment of intracranial aneurysms have expanded with the advent of the Guglielmi Detachable Cod (GDC) eight years ago. We have reviewed 435 cases of intracranial aneurysms treated at UCSF by endovascular means using the GDC system. Of these, 55% represent anterior circulation aneurysms, and 45% are located in the posterior circulation. Additionally, 55% of the aneurysms presented with subarachnoid hemorrhage (SAH) and 45% were unruptured. Factors which hindered optimal coiling include the following: wide aneurysm neck in relation to the overall aneurysm size, mural thrombus, giant aneurysm, arteries originating from the aneurysm sac, and middle cerebral location. After initial experience was gained, we tended to avoid these aneurysms especially in the non-ruptured group. This may be especially important in light of new epidemiological data suggesting that the natural history of unruptured aneurysms is significantly lower than previously thought. New technical developments which may reduce the risk of treating unruptured aneurysms include the two-dimensional coil, the three-dimensional coil, the balloon-assist technique for wide-necked aneurysms, and combined stent-coil procedures.
