The arteriovenous malformation (AVM) is a vascular malformation characterized by fistulas between arteries and veins forming a nidus, without interposition of capillary vessels and of which early draining vein is identified at the digital angiography. Potential reports of its existence date from the second century AD. Spetzler and Martin (S-M) proposed a classification considering three features and Lawton then added new predictors. A maximum of 10 score can be achieved by applying the modified S-M grade system. This classification guides decision-making and the possible choice of the multimodal treatment (surgery, radiosurgery and embolization). We discuss historical, pathological, clinical and therapeutic …

Introduction: Acute subdural hemorrhage (aSDH) in association with aneurismal subarachnoid hemorrhage (SAH) is a severe disease with an incidence of 0.5% to 7.9% of all SAH. Due to the rarity of aneurysmal aSDH, it remains difficult to define a comprehensive management protocol. In this case review, following the CARE guidelines, we show the hybrid management of this pathology to know the importance of using different types of neurosurgical treatments in case of two severe diseases in critical patients.

We present two patients who developed sudden onset cephalea and neurological impairment secondary to aneurysmal subarachnoid hemorrhage associated with acute subdural hematoma. …

BACKGROUND: Chiari's Malformation surgical treatment has significantly changed since the "classical" technique description by Gardner (1950). It is probably the most commonly performed approach, even when multiple techniques are available because no substantial changes nor any clear surgical objectives have been made. OBJECTIVE: To demonstrate a new cutting-edge surgical technique mastering the advantage of each surgical procedure ever described in the history of Chiari's Malformation establishing three critical points in surgical technique: clear patient-specific surgical goals, dynamic posterior fossa reconstruction, and extradural occipitoatlantal dense-adhesions release. METHODS: A comprehensive review of historically described approaches, proof of concept of surgical technique in …
