Treatment of wide-necked aneurysms with the Low-profile Visualized Intraluminal Support (LVIS Jr) device: a multicenter experience.

BACKGROUND: The Low-profile Visualized Intraluminal Support (LVIS) Junior stent is newly approved for the treatment of wide-necked intracranial aneurysms. OBJECTIVE: To report our multicenter experience with use of the LVIS Jr device. METHODS: The neurointerventional databases of the participating institutions were retrospectively reviewed for aneurysms treated with LVIS Jr from the time of Food and Drug Administration approval until February 2016. All patients in the study period were included. Clinical presentation, aneurysm location, aneurysm size, vessel size, procedural complications, clinical and imaging follow-up were included in the analysis. RESULTS: Eighty-five patients (54 female and 31 male) met the inclusion criteria for the study. Sixty-eight (80%) of the aneurysms were unruptured and the remainder were ruptured. The most common location of the treated aneurysms was anterior communicating artery (36%), middle cerebral artery bifurcation (22%), and basilar terminus (15%). The mean aneurysm size was 6.1 mm. The mean minimum parent vessel size was 2.3 mm. The LVIS Jr was successfully deployed in all but one case (99%). Initial angiographic results demonstrated Roy-Raymond class 1-2 occlusions in 61/84 patients (73%). At 6 months, 85% of the patients seen at follow-up had Roy-Raymond class 1-2 aneurysm occlusion. No procedure-related deaths occurred. Two cases of procedure-related complications (intraprocedural rupture and delayed rupture at day 2) were seen, leading to permanent neurologic morbidity. Both these cases were in patients with ruptured aneurysms. CONCLUSIONS: The LVIS Jr is a technically feasible, safe, and effective treatment for wide-necked intracranial aneurysms. Early results are promising but will need to be corroborated with longer-term follow-up.

Kyphoplasty versus percutaneous vertebroplasty using the traditional and the new side-opening cannula for osteoporotic vertebral fracture.

AIM: The aim of this article was to study the results of two different types of percutaneous vertebroplasty (PV) and kyphoplasty (KPs) to osteoporotic vertebral fractures (OVF). METHODS: It was prospectively analyzed a series of 47 PVs from January 2003 to February 2008, and a consecutive series 30 KPs from March 2008 to January 2010, performed for patients with painful OVFs. Twenty-five PVs were performed using the frontal-opening cannula (FOC) and 22 using the new side-opening cannula (SOC), randomly distributed in the PV group. RESULTS: The incidence of cement extrusion was 16.7% with KP, comparing with PV, it was 27.3% using the SOC (P<0.05) and 68,0% with the FOC (P<0.05), but comparing SOC with FOC, the cement extrusion was significantly lower using the SOC (P<0.05), all asymptomatic. The pain control was similar for all groups (P<0.05), with good improvement of pain in most of the patients, and there were no clinical relevant complications. CONCLUSION: The cement leakage was significantly reduced with the KP (16.7%) and the SOC (27.3%) for PV, in comparison with the FOC (68.0%). The cement extrusion was slightly lower with KP, but not a significant difference, comparing with SOC, increasing the safety of the procedure using both the KP and this new SOC.
