Abstract
Internal carotid artery blood blister-like aneurysms are challenging lesions that arise from the artery trunk at non-branching sites. They have been recognized since 1969 and are distinct from typical saccular aneurysms. Usually, these aneurysms are broad-based, with no clearly identifiable neck and have extremely friable and fragile walls, thus with a great propensity to cause subarachnoid hemorrhage and to rupture during treatment. Apparently, blister-like aneurysms are formed through an acquired defect of the inner layers (tunica intima and media) of the internal carotid artery wall, probably due to hemodynamic stress in the carotid siphon.Several surgical and endovascular techniques have been described for the treatment of these aneurysms, however, there is still no consensus on the best technique or method, exposing how challenging the treatment of internal carotid artery blister-like aneurysms is, for both neurosurgeons and neurointerventionists. In this chapter, we review the main aspects of the pathogenesis, diagnosis, and therapeutics and report our experience in the microsurgical treatment of these formidable lesions.

Abstract
PURPOSE Currently, there is an increasing tendency to refer only complex aneurysms for microsurgery. The formation of new neurosurgeons dedicated to open vascular neurosurgery becomes challenging in a situation in which complex aneurysms must be dealt with early in the career, raising questions about the safety of the learning curve. METHODS We analyzed the characteristics and surgical results of the first 300 consecutively treated patients after subarachnoid hemorrhage by a single neurosurgeon. The incidence of surgical complications and clinical outcomes during the learning curve were analyzed, looking for critical periods regarding patient safety. Microsurgical operative times were also studied. RESULTS A high frequency of wide-necked aneurysms was observed (70.3%), and, as a result, large (> 10 mm), MCA and paraclinoid aneurysms were overrepresented. A statistically significant correlation between surgical experience and clinical outcomes was observed, with progressive surgical experience resulting in a lower incidence of unfavorable outcomes. We also observed a higher frequency of major surgical complications, unfavorable clinical outcomes, and lower complete occlusion rates among the first 40 patients. Microsurgical operative times progressively and significantly decreased during the learning curve. CONCLUSIONS We observed a high prevalence of wide-necked aneurysms. Young neurosurgeons must be trained and prepared to deal with these aneurysms early in their careers. Although we observed a decrease in unfavorable results with cumulative surgical experience, the first 40 cases were associated with higher rates of major surgical complications, worse clinical outcomes, and lower complete occlusion rates, indicating that this period may be more critical to patient safety.

Abstract
Infectious intracranial aneurysms (IIAs) represent 2%–6% of all intracranial aneurysms and, classically, have been associated with bacterial or fungal agents. The authors report the case of a 42-year-old woman who presented with a typical history of subarachnoid hemorrhage. Digital subtraction angiography (DSA) showed an aneurysmal dilatation on the frontal M2 segment of the left middle cerebral artery (MCA). The patient was treated surgically, and multiple cysts were found in the left carotid and sylvian cisterns, associated with a dense inflammatory exudate that involved the MCA. The cysts were removed, and a fusiform aneurysmal dilatation was identified. The lesion was not amenable to direct clipping, so the authors wrapped it. Histopathological analysis of the removed cysts revealed the typical pattern of subarachnoid neurocysticercosis. The patient received cysticidal therapy with albendazole and corticosteroids, and she recovered uneventfully. Follow-up DSA performed 6 months after surgery showed complete resolution of the aneurysm. The authors performed a review of the literature and believe that there is sufficient evidence to affirm that the subarachnoid form of neurocysticercosis may lead to the development of an IIA and that Taenia solium should be listed among the possible etiological agents of IIAs, along with bacterial and fungal agents.

Abstract
OBJECTIVE Decompressive craniectomy (DC) is a widely used procedure in neurosurgery; however, few studies focus on the best surgical technique for the procedure. The authors' objective was to conduct a prospective randomized controlled trial comparing 2 techniques for performing DC: with watertight duraplasty and without watertight duraplasty (rapid-closure DC). METHODS The study population comprised patients ranging in age from 18 to 60 years who were admitted to the Neurotrauma Service of the Hospital da Restauração with a clinical indication for unilateral decompressive craniectomy. Patients were randomized by numbered envelopes into 2 groups: with watertight duraplasty (control group) and without watertight duraplasty (test group). After unilateral DC was completed, watertight duraplasty was performed in the control group, while in the test group, no watertight duraplasty was performed and the exposed parenchyma was covered with Surgicel and the remaining dura mater. Patients were then monitored daily from the date of surgery until hospital discharge or death. The primary end point was the incidence of surgical complications (CSF leak, wound infection, brain abscess, or subgaleal fluid collections). The following were analyzed as secondary end points: clinical outcome (analyzed using the Glasgow Outcome Scale [GOS]), surgical time, and hospital costs. RESULTS Fifty-eight patients were enrolled, 29 in each group. Three patients were excluded, leaving 27 in the test group and 28 in the control group. There were no significant differences between groups regarding age, Glasgow Coma Scale score at the time of surgery, GOS score, and number of postoperative follow-up days. There were 9 surgical complications (5 in the control group and 4 in the test group), with no significant differences between the groups. The mean surgical time in the control group was 132 minutes, while in the test group the average surgical time was 101 minutes, a difference of 31 minutes (p = 0.001). The mean reduction in total cost was $420.00 USD (a 23.4% reduction) per procedure in the test group. CONCLUSIONS Rapid-closure DC without watertight duraplasty is a safe procedure. It is not associated with a higher incidence of surgical complications (CSF leak, wound infection, brain abscess, or subgaleal fluid collections), and it decreased surgical time by 31 minutes on average. There was also a hospital cost reduction of $420.00 USD (23.4% reduction) per procedure. Clinical trial registration no.: NCT02594137 (clinicaltrials.gov).

Abstract
OBJECTIVE To associate the presence of language deficits with varying scores of the Fisher grading scale in patients with subarachnoid hemorrhage in the period preceding the treatment of aneurysm in the anterior circulation, as well as to compare the scores of this scale, identifying the grades more associated with the decline of language. METHODS Database analysis of 185 preoperative evaluations of language, through the Montreal Toulouse Protocol Alpha version and verbal fluency through CERAD battery, of patients from "Hospital da Restauração" with aneurysmal subarachnoid hemorrhage, divided according to the Fisher grading scale (Fisher I, II, III, or IV) and compared with a control group of individuals considered normal. RESULTS The various scores of the Fisher grading scale have different levels of language deficits, more pronounced as the amount of blood increases. Fisher III and IV scores are most associated with the decline of language. CONCLUSIONS Our study made it possible to obtain information not yet available in the literature, by correlating the various scores of the Fisher grading scale with language yet in the period preceding treatment.

Abstract
This study aimed to propose an alternative treatment for carotid cavernous fistula (CCF) using the balloon-assisted sinus coiling (BASC) technique and to describe this procedure in detail. Under general anesthesia, we performed the BASC procedure to treat five patients with traumatic CCF. Percutaneous access was obtained via the right femoral artery, and a 7F sheath was inserted, or alternatively, a bifemoral 6F approach was accomplished. A microcatheter was inserted into the cavernous sinus over a 0.014-inch microwire through the fistulous point; the microcatheter was placed distal from the fistula point, and a "U-turn" maneuver was performed. Through the same carotid access, a compliant balloon was advanced to cross the point of the fistula and cover the whole carotid tear. Large coils were inserted using the microcatheter in the cavernous sinus. Coils filled the adjacent cavernous sinus, respecting the balloon. Immediate complete angiographic resolution was achieved, and an early angiographic control (mean = 2.6 months) indicated complete stability without recanalization. The clinical follow-up has been uneventful without any recurrence (mean = 15.2 months). An endovascular approach is optimal for direct CCF. Because the detachable balloon has been withdrawn from the market, covered stenting requires antiplatelet therapy and its patency is unconfirmed, but cavernous sinus coiling remains an excellent treatment option. Currently, there is no detailed description of the BASC procedure. We provide detailed angiograms with suitable descriptions of the exact fistula point, and venous drainage pathways. Familiarity with these devices makes this technique effective, easy and safe.

Abstract
In this case an aneurysm of the right posterior communicating artery developed 11 months after an infundibular dilation of this artery had been angiographycally and surgically demonstrated. In the best of the authors' knowledge, there are only eleven such cases reported in the literature. This report brings about diagnostic and therapeutic questions regarding arterial infundibula and the need of a better understanding of those lesions.
