BACKGROUND The use of a stent during the acute post-hemorrhage period is controversial. We conducted a retrospective analysis on the clinical and angiographic outcomes of the ruptured aneurysms that were embolized with stent-assisted coiling or coiling-only. MATERIAL AND METHODS We reviewed data of 279 patients with 279 ruptured intracranial aneurysms who underwent coil embolization between July 2004 and June 2015. ⋯ Stent-assisted coiling for ruptured aneurysm, as compared with coiling-only, was not associated with an increased incidence of poor clinical outcome at follow-up. Aneurysm-occlusion status at follow-up were correlated with stent placement (p<0.001, odds ratio=5.85) and initial aneurysm-occlusion status (p=0.027, odds ratio=3.78). CONCLUSIONS Compared with coiling-only, stent-assisted coil placement may have better durability, with comparable safety for ruptured intracranial aneurysm.

BACKGROUND The thoracolumbar AO type A3 fracture is an incomplete burst fracture, which affects one vertebral body endplate. The objective of this study was to determine which of two minimal invasive techniques was more suitable for A3 fractures based on clinical and radiographic results. MATERIAL AND METHODS We studied 112 patients with A3 subtype fractures without neurological deficits. ⋯ CONCLUSIONS Our study found no significant differences in some clinical outcomes between the two groups. Both treatments were safe and effective for A3 subtype fractures. Nevertheless, given the radiation exposure, reduction of kyphosis, special equipment required, learning curve and hospitalization costs associated with PPSF, we concluded that MWPSF was a better choice for A3 subtype fractures.
