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.

Full article access for Neurosurgery subscribers.
BACKGROUND: The incidence of traumatic craniocervical artery dissection varies in published trauma series.
OBJECTIVE: To determine the frequency of traumatic craniocervical artery injury in polytrauma patients by using a standardized whole body trauma computed tomography (WBCT) with an adapted CT angiography (CTA) of the craniocervical vessels.
METHODS: 718 consecutive patients requiring a whole body trauma CT (16-row-multi-slice) due to the mechanism of their injury patterns and an Injury Severity Sale of greater than 16 were analyzed prospectively. After cranial scan, the CT angiography of the craniocervical vessels with 40 ml of iodinated contrast agent was performed using bolus tracking.

We evaluated the feasibility, usefulness, and limitations of near-infrared indocyanine green (ICG) videoangiography during procedures involving the extracranial vertebral artery (VA). Nine patients (2 women, 7 men; mean age, 55 years) were evaluated at 2 neurosurgical centers. Near-infrared ICG videoangiography was applied during transposition and rerouting of the first segment of VA (V1; n = 6) and during resection of neurinomas near the second (V2; n = 1) and third (V3; n = 2) segments of VA.
