The flow diverter device (FDD) is an important treatment method for cerebral aneurysms, especially for intracranial dissecting aneurysms. This paper is the result of FDD treatment for two cases of vertebral dissecting aneurysm (VADA) patients and short-term follow-up at 3 months. All two cases were targeted for unruptured cerebral aneurysm, and 4-vessel angiography was performed as a follow-up examination for 3 months after receiving the procedure. As result, it was possible to shorten the period of use of antiplatelet drugs. In the case of VADA, there are limitations in general coiling procedures or conventional surgical treatment methods. In that sense, the FDD treatment method can be a very effective alternative treatment of VADA

Background. The use and effectiveness of intraoperative cell salvage has been analyzed in many surgical specialties. Until now, no data exist evaluating the efficacy of intraoperative cell salvage in cerebral aneurysm surgery. Aim. To evaluate the efficacy and cost effectiveness of intraoperative cell salvage in cerebral aneurysm surgery. Methods. Data were collected retrospectively for all the patients who underwent cerebral aneurysm surgery at our institution between 2013 and 2019. Routinely, we apply blood salvage through autotransfusion. The cases were divided into a ruptured cerebral aneurysm group and a unruptured cerebral aneurysm group. Results. A total of 241 patients underwent cerebral aneurysm clipping. Of all the cerebral aneurysms, 116 were ruptured and 125 were unruptured and clipped electively. Age, location of the aneurysm, postoperative red blood cell count, intraoperative blood loss, and number of allogenic blood cell transfusions were statistically significantly different between the groups. The autotransfusion of salvaged blood could only be facilitated in eight cases with ruptured cerebral aneurysms and in none with unruptured cerebral aneurysms clipped electively (p < 0.01). Additionally, 35 patients with ruptured cerebral aneurysms and one patient with unruptured cerebral aneurysm required allogenic red blood cell transfusion after surgery, and 71 vs. 2 units of blood were transfused (p < 0.0001). In terms of cost effectiveness, a total of EUR 45,189 in 241 patients was spent to run the autotransfusion system, while EUR 13,797 was spent for allogenic blood transfusion. Conclusions. The use of cell salvage in patients with unruptured cerebral aneurysm, undergoing elective surgery, is not effective.

Background: An extremely tortuous superior cerebellar artery is a rare anomaly. We report a case of an extremely tortuous superior cerebellar artery mimicking an aneurysm. Case Description: A 77-year-old woman was initially diagnosed with unruptured cerebral aneurysm at the right basilar artery-superior cerebellar artery junction by magnetic resonance angiography. Catheter angiogram revealed that there was no apparent aneurysm at the basilar artery-superior cerebellar artery junction and the lesion was actually an extremely tortuous superior cerebellar artery. Conclusion: Although an extremely tortuous superior cerebellar artery is rare, it should be considered when examining other vascular lesions.

Objective: The coiling and clipping of unruptured cerebral aneurysms (UCAs) in older patients has increased rapidly, and aneurysm size was a significant factor for decision-making in the treatment of UCAs. The purpose of the study was to investigate the impact of age on the functional outcomes of patients between the small versus large UCAs.Methods: We conducted a retrospective study for consecutive cases of UCAs admitted from May 2011 to December 2020. According to the maximum diameter of UCA, patients were divided into small UCAs (≤ 5 mm) group and large UCAs (&gt;5 mm) group. Baseline characteristics, clinical complications, and outcomes of patients between the two groups were analyzed.Results: A total of 564 UCA patients received preventive treatment, including 165 small UCAs and 399 large UCAs. Compared with the small UCA group, the incidence of ischemia event in the large UCA group was significantly higher (7.3 vs. 2.4%; p = 0.029). Multivariable analysis demonstrating age (p = 0.006) and treatment modality (p &lt; 0.001) were independent risk factors associated with poor outcome for patients with large UCAs.Conclusions: Preventive treatment of small UCAs is safe and effective, but older patients with large UCAs are at high risk of poor outcome, and the operations should be more cautious.

BACKGROUND The pathogenesis and endovascular treatment strategy for spontaneously thrombosed unruptured cerebral aneurysms have not yet been comprehensively described. OBSERVATIONS The authors reported on a 78-year-old woman who had large bilateral unruptured cavernous carotid artery aneurysms that induced chronic disseminated intravascular coagulation and acquired factor XIII deficiency. The right aneurysm was symptomatic and partially thrombosed. Hemorrhagic diathesis and abnormal values of laboratory data improved after administration of recombinant human thrombomodulin followed by endovascular treatment in which three pipeline embolization devices were deployed for the right aneurysm. LESSONS To the best of the authors’ knowledge, this was the first report of an unruptured cerebral aneurysm leading to coagulation disorders with clinical manifestation that was treated successfully by endovascular intervention after intensive perioperative management.
