    Abstract: Multiple ways to access the dural carotid cavernous fistula have been described. The aim of the present study was to assess the results of embolization of a dural carotid cavernous fistula via different routes using endovascular accesses as a first-line strategy. Methods A retrospective data analysis of a consecutive series of 63 patients presenting with dural carotid cavernous fistula was performed. Results The dural carotid cavernous fistula was accessed by an endovascular approach in 58 patients (92.1%) and by direct puncture in five patients (7.9%). The inferior petrosal sinus was the main route accessed (65%). A recanalization of an occluded inferior petrosal sinus was obtained in 20.6% of cases. The access via either facial ophthalmic veins or the superior petrosal sinus was obtained in 20.6% and 3.1% of cases, respectively. Complete angiographic occlusion of a dural carotid cavernous fistula immediately after treatment was achieved in 53 patients (84.1%), whereas 10 patients (15.9%) displayed a partial occlusion. Treatment-related complications were observed in two patients (3.2%). Conclusions In this study, the endovascular approach allowed dural carotid cavernous fistula embolization in most patients. The inferior petrosal sinus, even when thrombosed, was the main route used to access the dural carotid cavernous fistula, followed by the facial vein, direct cavernous sinus puncture, and the superior petrosal sinus.

    Abstract: The benefits of mechanical thrombectomy in the treatment of patients with acute stroke due to large vessel occlusions (LVOs) have been extensively demonstrated by randomized trials and registries in developed countries. However, data on thrombectomy outside controlled trials are scarce in developing countries. The aim of this study was to assess the safety and efficacy, and to investigate the predictors for good and poor outcomes of thrombectomy for treatment of AIS due to anterior circulation LVOs in Brazil. Materials and Methods This was a single center registry of thrombectomy in the treatment of stroke caused by anterior circulation LVOs. Between 2011 and 2019, a total of 565 patients were included. Results the mean baseline NIHSS score on admission was 17.2. The average baseline ASPECTS was 8, and 91.0% of patients scored ≥6. Half of the patients received intravenous thrombolysis. The mean time from symptom onset to arterial puncture was 296.4 minutes. The mean procedure time was 61.4 minutes. The rates of the main outcomes were recanalization (TICI 2b-3) 85.6%, symptomatic intracranial hemorrhage (sICH) 8,1%, good clinical outcome (mRS=0-2) 43,5%, and mortality 22.1% at three months. Conclusions This study demonstrates the efficacy and safety of mechanical thrombectomy for treatment of patients with AIS of the anterior circulation in real-life conditions under limited facilities and resources. The results of the present study were relatively similar to those of large trials and population registers of developed countries.

    Thrombectomy for M2 occlusions and the role of the dominant branch

    Abstract: The benefits of thrombectomy for occlusion of M2 segments remain controversial. The aim of this study is to assess thrombectomy’s efficacy and safety in patients with M2 segment occlusion and associations between occlusion sites and anatomic variations of M1 division. Materials and methods A prospective series of 30 patients with acute ischemic stroke (AIS) resulting from M2 segment occlusion of the middle cerebral artery (MCA) who underwent thrombectomy was analyzed. The primary endpoint was assessed by the Extended Treatment in Cerebral Infarction scale (eTICI). The secondary endpoints were the incidence of symptomatic hemorrhagic transformation (sICH), mortality and good functional outcome at three months. Results The mean patient age was 69.2 years. The mean National Institutes Health Stroke Scale score (NIHSS) upon hospital admission was 16. The recanalization rates were eTICI 2b/3 in 90% and 2c/3 in 60% of the patients. Total recanalization of the M2 branch was achieved in 53% of patients. sICH incidence was 6.6%, the mortality rate was 30%, and a good functional outcome (mRS ≤2) was observed in 50% of the patients. Twenty-seven patients (90%) had a dominant M2 branch and all were occluded. Regarding the site of M2 occlusions, 74% of patients had proximal M2 occlusions. Conclusions Thrombectomy appears to be a safe and effective method for the treatment of acute M2 segment occlusions of the MCA. Most of the cases had a dominant M2 branch, and all of them were occluded. Larger studies are needed to verify the benefits of thrombectomy for different settings of M2 occlusions.
