Arteriovenous malformations (AVMs) consist of multiple connections between arteries and veins without a capillary bed and are characterized by an early draining vein.1,2 This pathology affects mainly young adults, and the morbimortality is caused mostly by rupture and hemorrhage.3-6 In this Video 1, we present a case of a 29-year-old female patient presenting with a sudden severe headache. Magnetic resonance imaging demonstrated the presence of a left AVM located at the fusiform gyrus, above the tentorium cerebelli, and angiography depicted those temporal branches of the left middle cerebral artery and posterior lateral choroidal arteries irrigated the AVM. In contrast, the main venous drainage was to the transverse sinus. ⋯ The patient consented to the procedure and to the publication of their image. In addition, the study was accepted by the ethics committee. The patient evolved without complications or deficits.

Incidence of stroke is increasing annually in China, the readmission rate of patients with stroke remains high. ⋯ The readmission of patients with stroke may be related to their physical activity function, chronic diseases, and socioeconomic status. When considering the factors predicting the readmission of patients with stroke, we cannot blindly draw on the results of relevant foreign studies.

There are still some patients with acute anterior circulation large vessel occlusion stroke experienced unsuccessful recanalization after endovascular thrombectomy (EVT). The efficacy of intravenous alteplase before thrombectomy for such patients is unknown. We performed this study to investigate whether prior intravenous alteplase could affect the outcome of patients with unsuccessful recanalization. ⋯ We found no evidence that prior intravenous alteplase could affect the clinical or imaging outcome in patients with acute anterior circulation large vessel occlusion stroke and unsuccessful recanalization after EVT.

To examine and compare the accuracy of measurements obtained from photogrammetric models versus direct measurements taken on dry skulls, with the aim to verify the feasibility of photogrammetry for quantitative analysis in microsurgical neuroanatomy. ⋯ Two photogrammetric models were validated as quantitative analysis techniques for laboratory neuroanatomical studies, showing acceptable measurement error, high intrarater and interrater reliability, and good to very good agreement compared with direct measurement on dry skulls, replacing expensive and time-consuming methods such as computed tomography scans and neuronavigation systems.
