Case ReportsSuperselective indocyanine green angiography for selective revascularization in the management of peripheral cerebral aneurysms.
This report describes the management of a fusiform peripheral middle cerebral artery aneurysm by endovascular parent artery occlusion under bypass protection. Localization of the recipient cortical artery was accomplished after craniotomy by superselective injection of diluted ICG dye via a microcatheter positioned proximal to the aneurysm. This report demonstrates that superselective ICG angiography can be a beneficial alternative technique to identify the best anastomosis site intraoperatively.

CT myelography for the planning and guidance of targeted epidural blood patches in patients with persistent spinal CSF leakage.
Intracranial hypotension is a rare cause of persistent headache mostly originating from a dural CSF leak. If a conservative treatment fails, a minimally invasive EBP can lead to a successful sealing of such a leak. Independent of the leakage site, an EBP is usually applied at the lumbar level with varying success. ⋯ Seven patients from our clinic were treated with a single targeted EBP in the lumbar or cervical spine. Within 24 hours, 6 patients experienced a considerable relief of symptoms; 1 patient went into remission after a repeat procedure. Our preliminary data suggest that a CT-guided, CT myelography-assisted targeted EBP is a safe and effective treatment for persistent spinal CSF leaks.

Safety and efficacy of CT-guided transforaminal cervical epidural steroid injections using a posterior approach.
Image-guided cervical transforaminal epidural injections play an important role in the management of cervical radicular pain syndromes. The safety and efficacy of these injections via an anterolateral approach has been well-studied. The goal of this retrospective review was to determine the safety and efficacy of CT-guided transforaminal epidural injections by using a posterior approach. ⋯ CT-guided transforaminal cervical epidural injections by using a posterior approach are safe and effective.

Dabigatran (Pradaxa) is a member of the relatively new class of antithrombotic drugs known as direct thrombin inhibitors (DTIs). It may supplant warfarin (Coumadin) in a number of applications as it may produce a more predictable, potent, and immediate anticoagulant effect, with fewer significant side effects and interactions, and requires less monitoring.

ReviewPeripheral nerve surgery: the role of high-resolution MR neurography.
High-resolution MRN is becoming increasingly available due to recent technical advancements, including higher magnetic field strengths (eg, 3T), 3D image acquisition, evolution of novel fat-suppression methods, and improved coil design. This review describes the MRN techniques for obtaining high-quality images of the peripheral nerves and their small branches and imaging findings in normal as well as injured nerves with relevant intraoperative correlations. Various microsurgical techniques in peripheral nerves, such as neurolysis, nerve repairs by using nerve grafts, and conduits are discussed, and MRN findings of surgically treated nerves are demonstrated.
