Conventional carotid catheterization is impossible in 2%-5% of acute stroke cases. Surgical carotid cutdown may be a necessary bailout strategy to allow for carotid access. We assessed the effectiveness and safety of surgical carotid cutdown for vascular access in interventional acute stroke treatment. ⋯ Carotid cutdown is an effective bailout strategy for acute stroke patients, in whom conventional catheterization is not possible.

Anatomical Feasibility of Right Oblique Approach for L5-S1 Oblique Lumbar Interbody Fusion.
We compared left and right vascular anatomy at the L5-S1 disc space and validated the anatomical feasibility of the right oblique approach for L5-S1 oblique lumbar interbody fusion. ⋯ The vessels on the right side of the L5-S1 disc were located more laterally, and most vessels on the right side were arteries accompanying PVAT, which might minimize vessel manipulation. These results indicate that the right side of the L5-S1 disc could provide feasible access for oblique lumbar interbody fusion at L5-S1.

Large brain arteriovenous malformations (AVMs) pose a management dilemma because of the limited success of any single treatment modality by itself. Surgery alone is associated with significant morbidity and mortality. Similarly, embolization alone has limited efficacy. Volume-staged Gamma Knife radiosurgery (VSGR) has been developed for the treatment of large AVMs to increase the efficacy and improve safety of treatment of these lesions. The aim of this study was to assess the efficacy and safety of VSGR technique for the treatment of large brain AVMs. ⋯ VSGR provides an effective and safe treatment option for large brain AVMs. Smaller AVM volume is associated with higher obliteration rate.

Dural reconstruction after transpetrosal approaches is complicated because complete primary closure of presigmoid dura mater is difficult to achieve. To address this problem, we use biocompatible polyglycolic acid (PGA) felt (Durawave) to reconstruct dural defects. To evaluate the use of PGA felt in dural reconstruction, we compared these results with those after conventional duraplasty using autologous fascia grafts. ⋯ Using PGA felt for presigmoid dura simplifies dural reconstruction because it obviates the need to suture in a deep field. PGA felt has the potential to prevent CSF-related complications after transpetrosal approaches.
