Klippel-Trenaunay syndrome and chiari I malformation. A case report and systematic review of the literature.

Introduction: Klippel-Trenaunay Syndrome (KTS) is a rare congenital condition characterized by vascular malformations, bone abnormalities, and limb overgrowth. The genetic basis of KTS is not fully understood, and the diagnosis relies on clinical features. Its clinical spectrum includes several neurosurgical diagnoses, such as cavernous hemangiomas, arteriovenous fistulas, and Chiari I malformation.

An Update on Spinal Dural Arteriovenous Fistulae: Case Series and Systematic Review.

Spinal dural arteriovenous fistulae (sDAVFs) are rare entities with delayed diagnosis, potentially dramatic clinical manifestations, and complex management. We aim to present our mini case series and perform an updated systematic review of the usual patient profile, to search for established prognostic factors, to compare the effectiveness and safety of surgical and endovascular intervention, and to discuss trends in therapeutic strategy. We retrospectively collected data from patients treated in our department in the last decade (2014-2024) and we systematically reviewed the literature according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria and searched the PubMed database for relevant articles published in the same period.
