Lessons to Be Remembered from a Dural Arteriovenous Fistula Mimicking Medulla and High Cervical Cord Glioma.

World Neurosurg 2018 May 7;113:312-315. Epub 2018 Mar 7.

Department of Neurosurgery, Teaching Hospital, Angers, France.

The radiological signs of intracranial dural arteriovenous fistulas (ICDAVFs) are heterogenous. While it is commonly accepted that hyper intense T2 wedge magnetic resonance imaging of the brainstem and cervical cord mainly concern gliomas, it is so far uncommon and probably unknown that ICDAVFs can imitate similar radiological pattern, especially with gadolinium contrast enhancement and cord enlargement. Thus the angiography is poorly documented in the diagnostic workup. Read More

Integration of Real-Time Intraoperative Contrast-Enhanced Ultrasound and Color Doppler Ultrasound in the Surgical Treatment of Spinal Cord Dural Arteriovenous Fistulas.

World Neurosurg 2018 Apr 2;112:138-142. Epub 2018 Feb 2.

Institute of Neurosurgery, Catholic University of Rome, Rome, Italy.

Background: In the surgical treatment of spinal dural arteriovenous fistulas (DAVFs), intraoperative definition of anatomic characteristics of the DAVF and identification of the fistulous point is mandatory to effectively exclude the DAVF.

Case Description: Intraoperative ultrasound and contrast-enhanced ultrasound integrated with color Doppler ultrasound was applied in the surgical setting for a cervical DAVF to identify the fistulous point and evaluate correct occlusion of the fistula.

Conclusions: Integration of intraoperative ultrasound and contrast-enhanced ultrasound is a simple, cost-effective technique that provides an opportunity for real-time dynamic visualization of DAVF vascular patterns, identification of the fistulous point, and assessment of correct exclusion.

Surgical ligation of spinal dural arteriovenous fistula.

Acta Neurochir (Wien) 2018 Jan 14;160(1):191-194. Epub 2017 Nov 14.

Department of Neurologic Surgery, Mayo Clinic, 200 First Street SW, Rochester, MN, 55902, USA.

Background: Spinal dural arteriovenous fistulas (SDAVFs) are abnormal arteriovenous shunts between a radicular artery and the radicular vein, located in the dorsal surface of the dura sleeve, which drains in a retrograde manner into the coronal venous plexus of the spinal cord without an interposed capillary network. This result is a venous hypertension that reduces spinal cord perfusion and leads to ischemia and edema. Spontaneous resolution is extremely rare and, once symptomatic, the typical course is further progression with increased neurological impairment. Read More

Spinal dural arteriovenous fistulas: the most frequent vascular malformations of the spinal cord.

Radiologia 2018 May - Jun;60(3):237-249. Epub 2017 Oct 28.

Servicio de Radiología, Hospital Universitario Miguel Servet, Zaragoza, España.

Spinal dural arteriovenous fistulas are produced by direct communication between the arterial and venous systems of the spinal cord, causing hypertension in the latter with spinal cord dysfunction. It is a rare pathology with unknown etiology and non-specific clinical symptoms that usually results in a delayed diagnosis. Often radiologists are the first to guide the disease towards an adequate diagnosis. Read More
