Microsurgical management of tentorial dural arteriovenous fistula: an analysis from the Consortium for Dural Arteriovenous Fistula Outcomes Research (CONDOR).
[OBJECTIVE] Dural arteriovenous fistulas (dAVFs) are rare cerebrovascular anomalies. Tentorial dAVFs (TDAVFs) have more aggressive features, making them prone to symptomatic presentations and hemorrhage. TDAVFs are heterogenous and require …

Spetzler-martin grade IV cerebral arteriovenous malformations in adult patients: a propensity-score matched analysis of resection and stereotactic radiosurgery.
Spetzler-Martin Grade IV arteriovenous malformations (AVMs) are challenging due to high risks associated with both treatment and natural progression. This study compares the outcomes of microsurgical resection and stereotactic radiosurgery …

Clinical Predictors of Inpatient Mortality and Poor Postoperative Course After aSAH Microsurgical Clipping: A 10-Year Experience from a Peruvian Tertiary Care Center.
: Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency with a high mortality rate requiring urgent treatment. This study aimed to identify clinical predictors of inpatient mortality and poor postoperative course after aSAH surgi…

Efficacy and safety of preoperative embolization in surgical treatment of brain arteriovenous malformations: a multicentre study with propensity score matching.
[BACKGROUND] Brain arteriovenous malformations (AVMs) are abnormal connections between feeding arteries and draining veins, associated with significant risks of haemorrhage, seizures and other neurological deficits. Preoperative embolizatio…

Safety and efficacy of preoperative embolization in the treatment of brain arteriovenous malformations with perinidal aneurysms and single draining vein: a multicenter study with propensity score-weighting.
[BACKGROUND AND OBJECTIVES] Arteriovenous malformations (AVMs) with perinidal aneurysms and single draining vein are associated with an elevated risk of rupture and increased procedural complexity. The role of preoperative embolization in t…

Microsurgical Treatment of Intracranial Dural Arteriovenous Fistulas: A Collaborative Investigation From the Multicenter Consortium for Dural Arteriovenous Fistula Outcomes Research.
[BACKGROUND AND OBJECTIVES] First-line therapy for most intracranial dural arteriovenous fistulas (dAVFs) is endovascular embolization, but some require microsurgical ligation due to limited endovascular accessibility, anticipated lower cur…

Management of failed flow diversion for intracranial aneurysm beyond the first 6 months of follow-up: an international Delphi consensus.
[OBJECTIVE] The placement of flow-diverting devices has become a common method of treating unruptured intracranial aneurysms of the internal carotid artery. The progressive improvement of aneurysm occlusion after treatment-with low complica…

Microsurgical Obliteration of Craniocervical Junction Dural Arteriovenous Fistulas: Multicenter Experience.
[BACKGROUND] Dural arteriovenous fistulas (dAVFs) located at craniocervical junction are extremely rare (1%-2% of intracranial/spinal dAVFs). Their angio-architectural complexity renders endovascular embolization to be challenging given mul…
-
Natural history, angiographic presentation and outcomes of anterior cranial fossa dural arteriovenous fistulas.
[BACKGROUND] Anterior cranial fossa dural arteriovenous fistulas (ACF-dAVFs) are aggressive vascular lesions. The pattern of venous drainage is the most important determinant of symptoms. Due to the absence of a venous sinus in the anterior…
-
Dural arteriovenous fistulas without cortical venous drainage: presentation, treatment, and outcomes.
[OBJECTIVE] Current evidence suggests that intracranial dural arteriovenous fistulas (dAVFs) without cortical venous drainage (CVD) have a benign clinical course. However, no large study has evaluated the safety and efficacy of current trea…
-
Fusiform Dilatation of the Internal Carotid Artery in Childhood-Onset Craniopharyngioma: A Systematic Review.
[OBJECTIVE] Patients with fusiform dilatation of the carotid artery (FDCA) following pediatric craniopharyngioma resection typically have a benign clinical course. We reviewed the neurosurgical literature for FDCA outcomes after resection o…

Minimally invasive resection of intracranial lesions using tubular retractors: a large, multi-surgeon, multi-institutional series.
[PURPOSE] Lesions located in subcortical areas are difficult to safely access. Tubular retractors have been increasingly used successfully with low complication profile to access lesions by minimizing brain retraction trauma and distributin…
