[Endovascular treatment of spinal dorsal intradural arteriovenous fistulas].

Background: The dorsal spinal intradural arteriovenous fistulas (DSIAF) are infrequent and complex injuries are underdiagnosed condition and disability. The aim is to present our experience in the endovascular management.

Methods: A retrospective and prospective study of patients with DSIAF treated by endovascular therapy (EVT) with n-butyl-cyanoacrylate during the period 2007-2013.

[Traumatic arteriovenous pial fistula masquerading as a carotid-cavernous fistula: an uncommon disorder with an unusual presentation].

Traumatic intracranial pial arteriovenous fistulae are infrequent lesions. Their cardinal signs have been related to mass effect and hemorrhage, but their clinical manifestations due to venous retrograde flow into ophthalmic veins has never been described. This phenomenon is usually seen in dural arteriovenous fistula draining to the cavernous sinus or carotid-cavernous sinus fistula.

[Endoscopic endonasal transsphenoidal approach for growth hormone-producing pituitary adenomas. Preliminary results].

Background: An endoscopic endonasal transsphenoidal approach is reported as less invasive, allowing an earlier discharge. Published series have never focused on its use in acromegalic patients.

Objective: To assess the effectiveness of an endoscopic endonasal transsphenoidal approach in the management of growth hormone-secreting adenomas.
