Delayed rupture of a previously coiled unruptured aneurysm is extremely rare, and no hemodynamic analysis of such aneurysms has been reported during the postprocedural course. ⋯ Heterogeneous hemodynamic characteristics were involved in the outcomes of intracranial aneurysm after endovascular treatment. High-flow impingement and WSS were associated with recanalization and regrowth, whereas low WSS was associated with aneurysm rupture.

This study aimed to investigate the hemodynamic changes induced by a flow diverter (FD) and coils in the treatment of internal carotid artery aneurysms, as well as to evaluate the effect of this treatment by using angiographic follow-up data. ⋯ On the basis of using the CFD method, adjunctive coiling with the Tubridge FD placement may significantly reduce intra-aneurysmal flow velocity and WSS, promoting thrombosis formation and occlusion of aneurysms.

The progression of scoliosis after fusion surgery is a poor prognostic factor of long-term outcomes in patients with degenerative lumbar stenosis (DLS). In this study we aimed to investigate changes in coronal alignment and identify risk factors related to progression of scoliosis after fusion. ⋯ The global magnitude of progression of the Cobb angle after short-segment lumbar fusion surgery in patients with DLS is similar to the natural curve progression of adult degenerative scoliosis.

Previous studies have demonstrated that increasing age is associated with decreased rates of operative management and gross total resection in patients with vestibular schwannomas. ⋯ In patients undergoing surgery for benign cranial nerve neoplasms, increasing age is associated with increased mortality, stroke, coma, and ventilator weaning failure. Composite complication rates are significantly greater in patients ≥70 years, with a near 80-fold increased risk of complications.
