Several microsurgical and endovascular techniques have been proposed for their treatment. The picket fence clipping technique uses fenestrated clips, that are stacked not to reconstruct the neck of the aneurysm, but to create a duct to normalize the cerebral flow by reconstructing the dome. We present four illustrative cases using the picket fence clipping technique. The aneurysms considered were of different locations (ICA, MCA, AComA), of large or giant size with wide necks, in which clipping attempt with a conventional technique was not possible, so that the use of non-conventional clipping techniques had to be applied with favorable results. In our experience we found this technique useful in large and giant, wide-necked aneurysms by reconstructing the parent vessel according to the concept of the ideal closure line in these previously unreported locations, thereby restoring normal cerebral circulation. The use of non-conventional techniques for clipping complex aneurysms can be used alone or in combination for adequate treatment, preserving cerebral circulation without compromising adequate exclusion of the aneurysm. The Picket fence technique is a feasible clipping technique that can be used as a less morbid option in large and giant aneurysms with wide necks.","PeriodicalId":94072,"journal":{"name":"Journal of cerebrovascular and endovascular neurosurgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-aneurysmal lesions and benign anatomical variants have both been proposed. In this study, we present the largest single cohort series on the natural history of CI.Methods: Retrospective review of prospective surveillance of 420 CI was undertaken in a single tertiary cerebrovascular centre. All CI diagnosed by a neuroradiologist, diagnosed on either a Magnetic resonance angiography (MRA), Computed tomography angiography (CTA) or Digital subtraction angiography (DSA) were eligible for inclusion. Imaging and demographic characteristics were recorded at baseline. CI growth and aneurysm transformation were the outcomes of interest. Groupwise comparison was conducted via Fischer exact testing. Kaplan Meir curves and Cox proportional hazard ratios were used to assess variables of interest with respect to time on surveillance.Results: 402 patients with 420 CI were surveyed over 2418 infundibula-years. Eleven CI (2.62%) grew on surveillance, and three (0.7%) transformed into aneurysms. Median time to growth was 85 months (36-263) and median time to aneurysm transformation was 112 months (96-142). Of the CI that grew, male sex and CI >2 mm at diagnosis were significant predictors of growth (all p<0.05). Of the CI that grew in surveillance, 2/11 (18.2%) transformed into aneurysms (p=0.001). Aneurysm transformation occurred at a rate of 1.27 per 1000 infundibula years. CI growth on surveillance (p= 0.00016) and size at diagnosis (p=0.038) remained significant predictors of aneurysm transformation on Kaplan Meir curves.Conclusions: The transformation of a CI to an aneurysm occurs at a low rate. A history of growth on surveillance imaging represents significant risk for aneurysm transformation.","PeriodicalId":94072,"journal":{"name":"Journal of cerebrovascular and endovascular neurosurgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were no significant procedural or access site complications. The mean radial diameter was 2.51 mm.Conclusions: The Walrus 0.087\" ID BGC is an effective tool that can safely be used via the radial artery using a sheathless approach, which helps to maximize the size of the catheter that can be used.

Our group previously demonstrated reduced radiation dose and exposure during diagnostic angiography by reducing the default pulse and frame rates. We applied the same technique for basic neuroendovascular interventions.Methods: We performed a retrospective review of prospectively acquired data after implementing a quality improvement protocol in which pulse rate and frame rate were reduced from 15 p/s to 7.5 p/s and 7.5 f/s to 4.0 f/s respectively. We studied consecutive, unilateral middle meningeal artery embolizations treated with particles. Total radiation dose, radiation per angiographic run, total radiation exposure, and exposure per run were calculated. Multivariable log-linear regression was performed to account for patient body mass index (BMI), number of angiographic runs, and number of vessels catheterized.Results: A total of 20 consecutive, unilateral middle meningeal artery embolizations were retrospectively analyzed. The radiation reduction protocol was associated with a 39.2% decrease in the total radiation dose and a 37.1% decrease in radiation dose per run. The protocol was associated with a 41.6% decrease in the total radiation exposure and a 39.5% decrease in exposure per run.Conclusions: Radiation reduction protocols can be readily applied to neuroendovascular interventions without increasing overall fluoroscopy time and reduce radiation dose and exposure by 39.2% and 41.6% respectively. We strongly encourage all interventionalists to be cognizant of pulse rate and frame rate when performing routine interventions.","PeriodicalId":94072,"journal":{"name":"Journal of cerebrovascular and endovascular neurosurgery","volume":" ","pages":"293-297"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11449538/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141877019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A drain was placed subgalealy and tip of drain was positioned between the bone flap and the deep temporalis. 1,637 cases (31%) had a subgaleal suction drain.

Univariate and multivariate logistic regression analyses were performed to determine the associated risk factors.Results: Fourteen cases (0.27%) of EDH requiring evacuation and 30 cases (0.57%) of wound complications were identified. Univariate analysis found that drain insertion, subarachnoid hemorrhage (SAH), and operation time were associated with EDH, while drain insertion, SAH, male gender, older age, and longer operation time were associated with wound complications.
