Free Article with CME: Characteristics of Posterior Cerebral Artery Aneurysms

Screen Shot 2014-07-30 at 7.58.50 AMBackground: Posterior cerebral artery (PCA) aneurysms are rare lesions. Because of their low incidence, the individual or institutional experience is usually limited.

Objective: To identify specific anatomic features related to PCA aneurysms based on the analyses of pretreatment angiograms.

Methods: We performed a detailed angiographic study of 81 patients with a diagnosis of 93 PCA aneurysms. Fifty-three patients underwent computed tomography angiography, 49 underwent digital subtraction angiography, and 6 underwent magnetic resonance angiography. Between 1980 and 2012, a total of 120 patients with 136 PCA aneurysms and 11 352 patients with 16 444 intracranial aneurysms were treated at our institutions.

Ahead of Print: ICG in the Surgical Management of Cerebral Arteriovenous Malformations

Screen Shot 2014-03-03 at 2.26.53 PMBackground: Indocyanine green (ICG) angiography is commonly used to map the vascular configuration of cerebral arteriovenous malformations (AVM) during resection.

Objective: To determine whether ICG improves rates of resection and clinical outcomes.

Methods: A retrospective chart review on all patients undergoing resection of an AVM by the senior author (RFS) between 2007-2011. Operative reports, hospital records, and radiographic imaging were used to determine utilization of ICG, incidence of residual disease, and clinical outcomes.

Simulation in Neurosurgery Supplement: Endovascular Simulators in Resident Training

Experience_With_a_Simulator_Based_AngiographyBackground: Simulation is an increasingly useful means of teaching in the era of duty hour restrictions. Since the completion of our diagnostic cerebral angiography simulator curriculum pilot program, we have performed this resident course at 2 Congress of Neurological Surgeons (CNS) annual meetings with larger participant numbers.

Objective: To report the ongoing results of these courses.

Methods: A 120-minute simulator-based training course was performed at 2 CNS annual meetings. Precourse written and simulator skills assessments were performed, followed by instructor-guided training on an endovascular simulator. Postcourse written and simulator practical assessments were then performed and compared with precourse scores.

Ahead of Print: MRI of AVMs After Radiosurgery

Background: Stereotactic radiosurgery is ideal for treating small cerebral arteriovenous malformations that are surgically inaccessible. However, given the inherent delay of AVM obliteration and the potential for radiosurgical failure, detailed evaluation of the neurovascular architecture is necessary to monitor persistence of residual flow. Modern imaging systems such as MRI and angiography allow clinicians to assess transnidus flow after radiosurgical intervention.

Objective: To determine the accuracy of an MRI diagnosis of complete thrombosis and identify variables that affect the precision of MRI assessment.

Methods: 120 patients were reviewed after receiving radiosurgery at the University of Florida from 1990-2010. Each patient had an MRI demonstrating AVM obliteration and an angiogram either confirming or denying AVM thrombosis.

Free CME Article: Ruptured Intracranial Aneurysms With Small Basal Outpouching

Background: Recognizing an aneurysmal basal rupture using angiographic evaluation is crucial for optimal treatment.

Objective: To evaluate the incidence of a small basal outpouching (the most common angiographic configuration suggesting a basal rupture), the incidence of a ruptured basal outpouching, and the results of surgical and endovascular treatments.

Methods: The occurrence of small basal outpouchings was determined in the initial angiographic examinations of 471 patients with a ruptured aneurysm. Information was also obtained from patient charts, surgical and interventional reports, operative video records, and reviews of radiological investigations.

Ahead of Print: Dissecting Aneurysm of the Posterior Spinal Artery

Background and Importance: Due to their rarity, the pathogenesis and clinical features of isolated spinal artery aneurysms are still unclear and their diagnoses and treatments are challenging. We report a case of an isolated posterior spinal artery aneurysm and review previous reports thoroughly to identify the general features of isolated spinal aneurysms.

Clinical Presentation: A 52-year-old man presented with abdominal pain followed by back pain and radiculopathy from subarachnoid hemorrhage in the spinal canal. The spinal angiogram illustrated presence of a dissecting aneurysm of the posterior spinal artery. He was treated by endovascular occlusion of the origin of the radiculopial artery and recovered completely.
