      In this study, arterial spin-labeling perfusion was used as a means to assess the well-known angiogenic activity seen in pituitary macroadenomas. Eleven patients with macroadenoma were studied and their ASL results correlated with histologic total microvascular density. The authors found that routine contrast enhancement did not correlate with microvascular density but CBF did and it also correlated with hypervascularity at surgery or postoperative bleeding in 4 instances.

      Five hundred aneurysms treated with a variety of self-expanding stents were clinically assessed and followed angiographically at 6–7 months postprocedure. Thromboembolic phenomena occurred in 21 patients and intraoperative rupture in 4. Initial complete occlusion was achieved in 42.2% progressing to 90.8% at follow-up. Early and late recanalizations were noted in 8% and 2%, respectively.

      Thrombus Attenuation Does Not Predict Angiographic Results of Mechanical Thrombectomy with Stent Retrievers

      American Journal of Neuroradiology November 2013, 34 (11) 2184-2186; DOI: https://doi.org/10.3174/ajnr.A3565

      This article examines whether MCA clot attenuation on initial CT studies determines the outcome of endovascular recanalization. The study was performed in 70 patients and showed that there were no significant differences between thrombus attenuations and successful recanalizations or periprocedural clot fragmentations. This investigation differs from others in that clot attenuation did not predict recanalization.
