Abstract
BACKGROUND Spinal vascular malformations (SVMs), including arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs), are a varied group of vascular lesions that can be subclassified according to localization, vascular structure, and hemodynamics. Early intervention is necessary to halt progression of disease and minimize irreversible dysfunction. We sought to characterize initial treatment success and recurrence rates following interventional treatment of various types of SVMs. METHODS A systematic review and meta-analysis were performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. SVMs were categorized into 4 groups: dural AVFs, perimedullary AVFs, intramedullary AVMs, and extradural-intradural AVMs (e.g., epidural, paraspinal). Initial occlusion, recurrence, and complication rates were compared using random-effects analysis. RESULTS There were 112 manuscripts included, with a total of 5626 patients with SVM. For treatment, 2735 patients underwent endovascular embolization, 2854 underwent surgical resection, and 37 underwent stereotactic radiosurgery. The initial treatment success and overall recurrence rates following surgical resection of all SVMs were 89.5% (95% CI: 80.5%-98.5%) and 2.3% (95% CI: 0.9%-3.7%), respectively. Those rates following endovascular embolization were 55.9% (95% CI: 30.3%-81.5%) and 27.7% (95% CI: 11.2%-44.2%), respectively. Higher rates of initial treatment success and lower rates of recurrence with surgery were observed in all subtypes compared to embolization. Overall complication rates were higher after embolization for each of the SVM categories. CONCLUSIONS Surgical resection of SVMs provided higher rates of initial complete occlusion and lower rates of recurrence than endovascular techniques. Attaining technical success through obliteration must still be weighed against clinical impact and natural history of the specific vascular malformation.

Intervention for unruptured high-grade intracranial dural arteriovenous fistulas: a multicenter study. J Neurosurg 2021; 136:962-970. [PMID: 34608140 DOI: 10.3171/2021.1.jns202799] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 01/20/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The risk-to-benefit profile of treating an unruptured high-grade dural arteriovenous fistula (dAVF) is not clearly defined. The aim of this multicenter retrospective cohort study was to compare the outcomes of different interventions with observation for unruptured high-grade dAVFs. METHODS The authors retrospectively reviewed dAVF patients from 12 institutions participating in the Consortium for Dural Arteriovenous Fistula Outcomes Research (CONDOR). Patients with unruptured high-grade (Borden type II or III) dAVFs were included and categorized into four groups (observation, embolization, surgery, and stereotactic radiosurgery [SRS]) based on the initial management. The primary outcome was defined as the modified Rankin Scale (mRS) score at final follow-up. Secondary outcomes were good outcome (mRS scores 0-2) at final follow-up, symptomatic improvement, all-cause mortality, and dAVF obliteration. The outcomes of each intervention group were compared against those of the observation group as a reference, with adjustment for differences in baseline characteristics. RESULTS The study included 415 dAVF patients, accounting for 29, 324, 43, and 19 in the observation, embolization, surgery, and SRS groups, respectively. The mean radiological and clinical follow-up durations were 21 and 25 months, respectively. Functional outcomes were similar for embolization, surgery, and SRS compared with observation. With observation as a reference, obliteration rates were higher after embolization (adjusted OR [aOR] 7.147, p = 0.010) and surgery (aOR 33.803, p < 0.001) and all-cause mortality was lower after embolization (imputed, aOR 0.171, p = 0.040). Hemorrhage rates per 1000 patient-years were 101 for observation versus 9, 22, and 0 for embolization (p = 0.022), surgery (p = 0.245), and SRS (p = 0.077), respectively. Nonhemorrhagic neurological deficit rates were similar between each intervention group versus observation. CONCLUSIONS Embolization and surgery for unruptured high-grade dAVFs afforded a greater likelihood of obliteration than did observation. Embolization also reduced the risk of death and dAVF-associated hemorrhage compared with conservative management over a modest follow-up period. These findings support embolization as the first-line treatment of choice for appropriately selected unruptured Borden type II and III dAVFs.

Spinal Dural Arteriovenous Fistulas: Clinical Results and Quality of Life Assessment with Surgical Treatment as a Crucial Therapy. The Joint Experience of Two Centers. World Neurosurg 2018; 122:e270-e278. [PMID: 30339911 DOI: 10.1016/j.wneu.2018.10.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Revised: 10/01/2018] [Accepted: 10/03/2018] [Indexed: 12/30/2022]
Abstract
OBJECTIVE Dorsal intradural arteriovenous fistulas (AVFs) consist of a direct connection between a radicular feeding artery and the coronal venous plexus; this direct connection leads to arterialization of the venous plexus, venous congestion, and myelopathy. Controversy still exists regarding the best treatment modality of spinal dural AVFs. Surgical disconnection of spinal dural AVFs is a straightforward procedure with a high success rate and virtually no risk of recurrence or incomplete treatment. To identify factors associated with the clinical progression of dorsal intradural AVFs and quantify the range of surgical outcomes in terms of neurologic improvement as well as patients' perception of quality of life (QOL). METHODS A retrospective observational study of 19 consecutive patients treated with surgery over a 10-year period was carried out. We analyzed surgical results and clinical outcomes. We also evaluated the impact of this disease and its sequelae on the patients' postoperative health-related QOL. RESULTS The surgical procedure showed good results in terms of neurologic improvement as well as patients' perception of QOL. CONCLUSIONS Our series confirmed that surgical obliteration of dorsal intradural AVFs is an effective and safe procedure. The results of this retrospective analysis make us believe that surgery, given its low morbidity and high success rate, represents a safe and effective first therapeutic option for these spinal vascular malformations. It could be considered to avoid unsuccessful endovascular attempts that could delay the definitive treatment of this disease. The surgical procedure showed good results in terms of neurologic improvement as well as patients' perception of QOL.

Abstract
Background: Spinal dural arteriovenous fistulas (DAVFs) are rare lesions that lead to venous congestion and ischemic injury resulting in neurologic deterioration. Here we present a patient diagnosed with glioblastoma multiforme (GBM) who became symptomatic from a spinal DAVF after a diagnostic high-volume lumbar puncture (LP). Case Description: When a 72-year-old female developed partial seizures in her left upper extremity without other focal neurological deficits, she underwent a magnetic resonance imaging (MRI) scan of the brain. The MRI revealed a right frontal/posterior corpus callosal lesion. She next had a MR-guided high-volume LP. A GBM was diagnosed following a biopsy. Postoperatively, after the LP, she was noted to have bilateral deltoid and bilateral 4/5 lower extremity weakness, with diffuse hyperreflexia. The MRI and magnetic resonance angiogram (MRA) of the cervical spine demonstrated a large venous varix at the C5-C6 level within the left neural foramen. She underwent successful complete embolization of two thyrocervical branches with direct communication to an enlarged anterior spinal artery. One month later, her neurological examination returned to baseline; she was walking independently with only 4+/5 residual weakness in her left lower extremity. Conclusions: Here we report a patient with a cranial GBM and an incidental cervical spinal C5-C6 DAVF that became symptomatic after a high-volume LP. It is possible that the high-volume LP increased vascular congestion, thus precipitating the onset of cervical myelopathy.
