Review Meta Analysis
The role of sonolysis and sonothrombolysis in acute ischemic stroke: a systematic review and meta-analysis of randomized controlled trials and case-control studies.
To assess the evidence on the safety and efficacy of sonothrombolysis in acute stroke. ⋯ This novel treatment appears safe and effective. The evidence of microsphere as an enhancement of sonothrombolysis is evolving.

Distinguishing BNCT from chordoma with imaging is critical because of the profound differences in prognosis and management. Yet few reports define the variable imaging characteristics of BNCT. This study aims to evaluate the prevalence and characteristics of BNCT. ⋯ Many notochordal lesions do not fit neatly into the diagnostic criteria for either EP or chordoma. It may be useful to consider these atypical cases along a spectrum of notochord remnant lesions. Close inspection of imaging reveals BNCTs at a similar frequency to its pathologic prevalence. BNCTs such as EP vary in size and may be easily overlooked.

In many intracranial disease states, monitoring of intracranial pressure (ICP) is essential to evaluate response to the therapeutic measures as well as estimation of prognosis. Although, direct estimation of ICP is reliable, it is invasive and not possible in all patients. Transcranial Doppler (TCD) ultrasonography is a bedside and noninvasive technique that provides reliable and real-time information about cerebral hemodynamics. We present a case of extensive and progressive cerebral venous sinus thrombosis in which TCD served as an excellent tool for monitoring ICP and the serial observations correlated closely with clinical status and ophthalmological findings.

Clinical Trial
Endovascular treatment of posttraumatic carotid-cavernous fistulas and pseudoaneurysms with covered stents.
The treatment of posttraumatic direct carotid-cavernous fistulas (TCCFs) with detachable balloons (DBs) is associated with relatively high recanalization rate. The aim of this study was to evaluate the feasibility of using covered stents in patients with posttraumatic carotid-cavernous fistulas (CCFs) and pseudoaneurysms. ⋯ These preliminary results indicate that the use of a covered stent is a feasible procedure for the treatment CCFs and pseudoaneurysms.

Dolichoectasia (DE) is a vasculopathy that consists of abnormal elongation and dilatation of arteries. The objective of this study is to evaluate the frequency of DE in an unselected population and assess different diagnostic methods. ⋯ A TCV-adjusted intracranial arterial diameter ≥2 SD is proposed as a useful DE definition. The variability in the prevalence of DE depending on the methods used underscores the need to agree on a reliable, universal definition of DE.
