Cerebral arteriovenous malformations are an infrequent pathology, of which fistulous malformations are the least common. Surgical clinical management is not fully defined, so analyzing the efficacy of embolization in these patients is an important scientific contribution to society. A 28-year-old male patient with headache of 10/10 on the visual analog pain scale. Imaging studies were performed and showed intraparenchymal hemorrhage; computed tomography angiography revealed a ruptured cerebral arteriovenous malformation in the temporo-occipital region dependent on the middle cerebral artery; complex endovascular embolization was performed, with favorable results in his evolution. In conclusion, embolization as a treatment for hemorrhagic temporo-occipital arteriovenous malformation is a viable alternative in patients with stage IV on the Spetzler scale.

Objective. To describe febrile neutropenia in oncohematological patients in Latin America, its bacteriological profle and resistance.  Methods. A systematic review study was carried out, following PRISMA  criteria in order to respond to the research objective. Information was  collected from observational studies,  review articles, meta-analysis,  systematic reviews, in English and Spanish. The review was carried out in the LILACS, PubMed, ScienceDirect and SciELO databases, using Medical Subject Headings (MeSH) terms and health sciences descriptors (DeCS) for the search strategy. Results. A total of 9 articles were selected, showing that the predominant germs associated  with patients with febrile neutropenia are gram-negative bacilli, with  Escherichia coli being the main and  least resistant. On the other hand, Klebsiella pneumoniae and  Pseudomona aeruginosa are more resista...
