Spinal Arteriovenous Malformations

Spinal vascular malformations are rare, with dural arteriovenous fistulas (AVFs) accounting for the majority of the pathology. Unlike spinal arteriovenous malformations, which cause abrupt neurological change as a result of hemorrhage, spinal dural AVFs tend to result in a progressive myelopathy through venous congestion and cord edema. If diagnosed and treated early with endovascular embolization or microsurgery, some deficits may be reversible.

Spinal Dural Arteriovenous Fistulas

Spinal vascular malformations are uncommon yet important spinal pathologies commonly classified in congenital and acquired lesions. Spinal lipomas consist of three subtypes: intramedullary lipomas, lipomyelo(meningo)celes and lipomas of the filum. Although the association of spinal arteriovenous malformations (AVM) with other congenital anomalies is well known, the coexistence of dural arteriovenous fistulas (AVF) and tethered spinal cord is exceptionally rare and only eight cases have been reported. We present two cases from our institution and speculate on the possible origin of such a rare but insidious association. We review the current literature with a focus on possible pitfalls in diagnosis and treatment.

Spinal Dural Arteriovenous Fistulas

Abstract: Spinal dural arteriovenous fistulas are a rare cause of congestive myelopathy. Symptoms are insidious in onset and may be confused with degenerative spinal disease. MRI characteristically shows edema of the spinal cord with serpiginous flow voids that follow the surface of the spinal cord. Careful evaluation with spinal angiography is required to ensure accurate diagnosis. Spinal dural arteriovenous fistulas differ from spinal arteriovenous malformations in that most fistulas have only a single fistulous point without a nidus. Spinal dural arteriovenous fistulas may be treated successfully with either surgical resection or endovascular embolization depending on their anatomy. Earlier treatment is associated with better outcomes.

Spinal Avm

✓ Among spinal arteriovenous malformations (AVMs), dural arteriovenous fistulas (DAVFs) should be distinguished from intradural AVMs. The authors report the unusual and well-documented case of a 49-year-old man who suffered from a rapidly progressive myelopathy. Two concurrent spinal AVMs (one DAVF and one intradural direct AVF [Anson—Spetzler Type IV-B AVM]) were found located in the midthoracic region and in the conus medullaris, respectively. Both AVMs were successfully treated by surgery. To the authors' knowledge, the association of these two pathological entities has not been previously described. Clinically, if the patient fails to improve or deteriorates after the treatment of a spinal AVM, the presence of another AVM should be investigated by repeated angiography, especially if a complete spinal angiography study was not initially performed.
