Fracture and migration of a retained microcatheter into the cauda equina after endovascular neurointervention for dural arteriovenous fistula as a rare cause of tethered spinal cord: case report.

J Neurosurg Spine 2019 Dec 13:1-4. Epub 2019 Dec 13.

3Department of Radiology, Bahcesehir University School of Medicine, Istanbul, Turkey.

The evaluation of spinal cord vascular malformations in neuroradiology departments remains valid for both diagnosis and endovascular embolization, and for adjuvant as well as definitive treatment. The most commonly encountered complications of endovascular approaches are the recurrence or the incomplete embolization of the lesion and accidental damage to the medullary arteries, which leads to spinal cord infarction. Failure to remember a microcatheter in the abdominal aorta after catheterization is an underestimated complication. Read More

Challenging dogma: report of a spinal cord arteriovenous malformation as an acquired lesion in a pediatric patient.

J Neurosurg Spine 2019 Oct;32(2):302-304

Departments of1Neurosurgery.

Spinal cord intramedullary arteriovenous malformations (AVMs) have classically been considered congenital lesions that are present from birth. The reason for this dogmatic principal is the fact that a vast majority of these lesions present in pediatric and young adult patients. Interestingly, while many authors have demonstrated the development of de novo nidus-type brain AVMs, there have been no reported cases of a de novo intramedullary or perimedullary AVM of the spine.

Fluorescein-guided surgery for spinal dural arteriovenous fistulas: A short series.

J Clin Neurosci 2019 Dec 12;70:226-228. Epub 2019 Aug 12.

Department of Neurosurgery, Rennes University Hospital, 2, rue Henri Le Guilloux, 35033 Rennes Cedex 9, France. Electronic address:

The gold standard treatment of spinal dural arteriovenous fistulas (SDAVF) is surgical exclusion. The main surgical challenge is to localize the origin of the shunting vein and to ensure its complete exclusion. In that context, intra operative angiography technologies have been developed, such as fluorescein video angiography (FVA). Read More

The role of spinal angiography in the evaluation and treatment of pediatric spinal vascular pathology: a case series and systematic review.

Childs Nerv Syst 2020 02 14;36(2):325-332. Epub 2019 Aug 14.

Division of Pediatric Neurosurgery, Texas Children's Hospital, 6701 Fannin St., Ste. 1230, Houston, TX, 77030, USA.

Object: While it has been extensively studied in adults, the role of spinal angiography in children with suspected spinal vascular malformations is not fully characterized. With special implications regarding technique, radiation dose, and pathology, we sought to review our single-center experience with pediatric spinal vascular pathology and use a systematic review of the literature to further identify its role in pediatrics.

Methods: A retrospective chart review was conducted under IRB approval for all patients age 0-18 years old who underwent spinal angiography at our institution between 2007 and 2018 for concern for spinal vascular pathology. Read More

Cauda Equina Occupation Ratio as a New Imaging Parameter for the Evaluation of Spinal Dural Arteriovenous Fistulae.

World Neurosurg 2019 Oct 12;130:e1020-e1027. Epub 2019 Jul 12.

Department of Neurosurgery, Graduate School of Medical and Dental Sciences, Kagoshima University, Kagoshima, Japan.

Background: Because spinal dural arteriovenous fistulae (SDAVF) are rare and their clinical presentation is nonspecific, they are often overlooked during diagnostic evaluations. Typical magnetic resonance imaging (MRI) findings are intramedullary T2-weighted signal hyperintensity and perimedullary flow voids. There are few reports on the characteristic signs of the cauda equina. Read More

Spinal Vascular Malformations: Treatment and Outcome.

World Neurosurg 2019 Oct 11;130:e953-e960. Epub 2019 Jul 11.

Department of Neurosurgery, Istanbul University-Cerrahpasa, Cerrahpasa Medical Faculty, Istanbul, Turkey.

Background: Vascular malformations of the spinal cord are a rare and complex clinical entity and can lead to severe morbidity with progressive spinal cord symptoms if not treated properly. In early stages, the disease is characterized by slowly progressive, nonspecific symptoms, such as gait disturbance, paresthesia, diffuse sensory symptoms, and radicular pain; in the late stages, bowel and bladder incontinence, erectile dysfunction, and urinary retention may develop. In recent decades, understanding and treatment of spinal vascular malformations have improved with the evolution of diagnostic tools and treatment modalities; however, it is still difficult to manage these cases because of the complexity of the pathology.

The contributions of Otto Hebold and Julius Gaupp to the study of spinal vascular malformations: Original documents and historical context.

Interv Neuroradiol 2019 Dec 7;25(6):604-612. Epub 2019 Jul 7.

Division of Interventional Neuroradiology, The Johns Hopkins Hospital, Baltimore, USA.

Book chapters and journal articles dealing with spinal cord vascular malformations often reference Otto Hebold and Julius Gaupp, but frequently misrepresent the observations published by the two German authors in the late 19th century. The purpose of this paper is to provide a better appreciation of these important contributions based on abridged translations of original documents set in their historical context, notably regarding the landmark works of Brasch, Raymond and Cestan, and Lindenmann. It is concluded that Gaupp offered the first reliable description of a perimedullary arteriovenous fistula while the lesion reported by Hebold was not a spinal vascular malformation. Read More

Arteriovenous Fistula of the Filum Terminale: A Case Report and Review of the Literature.

World Neurosurg 2019 Oct 26;130:42-49. Epub 2019 Jun 26.

Department of Neurological Surgery, Tulane University School of Medicine, New Orleans, Louisiana, USA. Electronic address:

Background: Fistulas of the filum terminale are rare lesions that result from a fistulous connection between the artery and vein of the filum terminale. These lesions often present as progressive thoracic myelopathy secondary to venous hypertension that is transmitted to the coronal venous plexus of the spinal cord. Frequently, filum fistulas will be associated with lumbar stenosis and likely form as a result of chronic inflammation and compression. Read More

Intraoperative Computed Tomography Navigation-Assisted Resection of Symptomatic Intramedullary Spinal Cord Cavernoma: A Technical Note and Case Report.

World Neurosurg 2019 Sep 21;129:311-317. Epub 2019 Jun 21.

Warren Alpert Medical School of Brown University, Department of Neurosurgery and Norman Prince Neurosciences Institute, Rhode Island Hospital, Providence, Rhode Island, USA. Electronic address:

Background: Intramedullary spinal cord cavernous malformations (ISCCMs) are a rare entity. Most commonly, ISCCMs present with neurologic decline from lesion hemorrhage, which can be catastrophic and irreversible irrespective of surgical intervention. Given the challenging anatomic location of these lesions in highly critical neurologic areas, precise surgical localization and visualization is necessary to limit collateral damage during resection particularly for deep ISCCMs that do not present to a pial surface.

Natural history of spinal cord arteriovenous shunts: an observational study.

Brain 2019 08;142(8):2265-2275

Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China.

The natural history of intradural spinal cord arteriovenous shunts is unknown. We performed an observational study in a consecutive patient cohort with symptomatic intradural spinal cord arteriovenous shunts who were admitted to three institutes to investigate the clinical course of this complex disease, which would provide valuable evidence to inform clinical decision-making. The clinical course of patients with symptomatic intradural spinal cord arteriovenous shunts from initial presentation to occurrence of clinical deterioration, initiation of treatment, or last follow-up was analysed.
