Background: Adverse outcomes after aneurysm clipping can be potentially reversible, when managed appropriately.
Methods: This is a case report describing kinking of a perforator due to clipping of parent vessel aneurysm.
Results: Complete recovery of a high-grade motor deficit was achieved after instant reintervention with application of smaller clips in combination with gelfoam soaked in papaverine.
Background: For sustainability of arteriovenous malformation (AVM) surgery, results from early career cerebrovascular neurosurgeons (ECCNs) must be acceptably safe.
Objective: To determine whether ECCNs performance of Spetzler-Ponce Class A AVM (SPC A) resection can be acceptably safe.
Methods: ECCNs completing a cerebrovascular fellowship (2004-2015) with the last author were included.
Background: Intervention for brain arteriovenous malformations (bAVMs) should aim at treatment that is safe and effective.
Objective: To analyze a prospective database to derive the probability of neurological deficit and adjust this risk for effectively treated bAVMs (complication-effectiveness analysis [CEA]).
Methods: First, we calculated the percentage of surgical complications leading to a modified Rankin Scale >1 at 12 months after surgery for each Spetzler-Ponce class (SPC).
Background: The risk of hemorrhage from a brain arteriovenous malformation (bAVM) is increased when an associated proximal intracranial aneurysm (APIA) is present. Identifying factors that are associated with APIA may influence the prediction of hemorrhage in patients with bAVM.
Objective: To identify patient- and bAVM-specific factors associated with APIA.
Background: The aim of intervention for unruptured intracranial aneurysms (UIAs) is safe, effective treatment.
Objective: To analyze a prospective database for variables influencing the risk of surgery to produce a risk model adjusting this risk for effectively treated aneurysms.
Methods: First, we identified variables to create a model from multiple logistic regression for complications of surgery leading to a 12-month modified Rankin Scale score >1.
Background: Long-term patency of extracranial-to-intracranial (EC-IC) vein bypass is poorly understood.
Objective: We report our experience of patency of arterial pedicle grafts and interposition vein grafts for the purpose of EC-IC bypass.
Methods: We analyzed 294 consecutive patients who underwent 178 intracranial arterial pedicle bypass procedures and 152 intracranial vein bypass procedures.
Object: In this paper the authors' goal was to evaluate whether resident neurosurgeons participating in entry-level aneurysm surgery have a negative impact on patient outcomes.
Methods: The authors searched the database for entry-level aneurysm surgeries (that is, those < or =10 mm and located in the internal carotid artery [beyond the paraclinoid segment] and middle cerebral artery) performed in 1991 through 2005. The presence or absence of an advanced resident (in his/her last 3 years of residency) was noted.
