Diagnosis and treatment of vascular malformations of the brain.

Gross BA, Du R.Author information Department of Neurological Surgery, Brigham and Women's Hospital and Harvard Medical School, 75 Francis St, Boston, MA, 02115, USA.AbstractOPINION STATEMENT: Vascular malformations of the brain are often found in the workup of intracranial hemorrhage, seizures, focal neurological deficits, or headaches. Although CT-angiography may reveal an underlying arteriovenous malformation (AVM) or arteriovenous fistula (AVF), other vascular malformations are not easily evaluated on CT and are better seen on magnetic resonance imaging. For the evaluation of AVMs and AVFs, formal digital subtraction angiography remains the gold standard. In the case of AVMs, AVFs, or cavernous malformations (CMs), the lesion may serve as the etiologic source of the symptoms and thus warrant treatment. When feasible, microsurgical resection is the optimal treatment option for AVMs and CMs. Endovascular embolization may serve as a crucial adjunct to microsurgery in the treatment of AVMs. Depending on their vascular anatomy, AVFs may be treated by either endovascular embolization or microsurgery. For inoperable AVMs and dural AVFs necessitating treatment, stereotactic radiosurgery (SRS) may serve as a viable treatment alternative. Capillary telangiectasias and developmental venous anomalies (DVAs) are often incidental findings; they may be found in association with CMs but are not generally considered targets for treatment. Herein, we review diagnostic methods, natural history, and treatment options for these cerebral vascular malformations.

"Loop-like formation" in the cortical venous reflux of dural arteriovenous fistula with intracranial hemorrhage.

Koyanagi M1, Sakai N2, Adachi H2, Ueno Y2, Kunieda T2, Imamura H2, Kikuchi H2.Author information 1Department of Neurosurgery, Kobe City Medical Center General Hospital; Kobe, Hyogo, Japan. Electronic address: koyanagm@kuhp.kyoto-u.ac.jp.2Department of Neurosurgery, Kobe City Medical Center General Hospital; Kobe, Hyogo, Japan.AbstractBACKGROUND AND PURPOSE: Cortical venous reflux (CVR) in dural arteriovenous fistulas (AVFs) is a well-known risk factor for intracranial hemorrhage. However, the impact of the angiographic characteristics of CVR on the risk of intracranial hemorrhage remains unclear. This study retrospectively reviewed the angioarchitectural features of CVR to assess their influence on the risk of intracranial hemorrhage in dural AVFs.

Bilateral cervical spinal dural arteriovenous fistulas with intracranial venous drainage mimicking a foramen magnum dural arteriovenous fistula.

Hetts SW, English JD, Stiver SI, Singh V, Yee EJ, Cooke DL, Halbach VV.Author information Department of Radiology and Biomedical Imaging; University of California; San Francisco, CA, USA - Steven.Hetts@ucsf.edu.AbstractWe describe a unique case of bilateral cervical spinal dural arteriovenous fistulas mimicking an intracranial dural arteriovenous fistula near the foramen magnum. We review its detection via MRI and digital subtraction angiography and subsequent management through surgical intervention. Pitfalls in diagnostic angiography are discussed with reference to accurate location of the fistula site. The venous anastomotic connections of the posterior midline spinal vein to the medial posterior medullary vein, posterior fossa bridging veins, and dural venous sinuses of the skull base are discussed with reference to problem-solving in this complex case. The mechanism of myelopathy through venous hypertension produced by spinal dural fistulas is also emphasized.
