Sixty-four-row multislice computed tomographic angiography (CTA) has great potential for use in vascular studies. The aim of our study was to compare 64-slice CTA with three-dimensional rotational angiography (3DRA) in the detection and characterization of intracranial aneurysms with special attention to smaller (<3-mm) aneurysms. ⋯ Sixty-four-slice CTA is a highly accurate imaging examination of the first-line imaging technique for detecting and characterizing intracranial aneurysms including <3-mm aneurysms.

To review the authors' experience with Gamma Knife radiosurgery (GKR) for small recurrent high-grade gliomas (HGGs) following prior radical resection, external-beam radiation therapy (EBRT), and chemotherapy with temozolomide (TMZ). ⋯ GKR provided good local tumor control in this group of clinically stable and predominantly high-functioning patients with small recurrent HGGs after radical resection. Meaningful survival times after GKR were seen. GKR can be considered for selected patients with recurrent HGGs.

This study sought to report on the utility and safety of the flexible-fiber CO2 laser in endoscopic endonasal transsphenoidal surgery. ⋯ We found that CO2-laser-assisted endoscopic endonasal transsphenoidal surgery for sellar tumors is a minimally invasive approach using a tool that is quick and effective at cutting and coagulation. The surgery has a low rate of complication, and no laser-related complications were encountered. The laser fiber allows the surgeon to safely cut and coagulate without the line-of-sight problems encountered with conventional CO2 lasers. Further studies are recommended to further define its role in endoscopic endonasal sellar surgery.

To evaluate the long-term imaging and clinical outcomes of patients with brainstem arteriovenous malformations (AVMs) treated with Gamma Knife surgery (GKS). ⋯ Given the poor surgical outcome of brainstem AVMs, the results of 59% nidus obliteration and 6% permanent neurologic deficits make GKS a reasonable management of these difficult lesions.

Video-assisted thoracic surgery (VATS) is a less-invasive alternative to open thoracotomy. According to evidence-based medicine methodology, VATS is associated with better outcomes and the same complication rate as open thoracotomy. ⋯ The two presented cases show that VATS is not without severe complications, as evidence-based medicine methodology suggests. Surgical findings in our patients imply that if this type of complication happens, early surgical exploration could be the best option for the patients.
