Bone cement enhancement by percutaneous vertebroplasty (PVP) for the treatment of osteoporotic vertebral compression fractures remains unapproved, as it has not been fully evaluated in Japan. The current multicenter study was conducted in Japan to verify the safety and efficacy of PVP in patients with painful osteoporotic vertebral fractures.Material and Methods: In this retrospective study, we referred to previous studies to evaluate the noninferiority of PVP to balloon kyphoplasty (BKP). We reviewed consecutive patient data from April 2017 to March 2018 from four institutions based on the medical records of the intervention. We statistically investigated the adverse events due to cement leakage or other factors associated with PVP, and new vertebral compression fractures after PVP were evaluated for safety, pain relief, and gait improvement.Results: This study included 485 patients; most of whom were in the middle-to oldest-age groups (mean age, 81.4 years). No serious adverse events were reported in patients available for safety evaluation (n = 485). Cement leakage and new vertebral compression fractures occurred in 35.7% and 18.6% (26.2%-38.4% and 8.9%-20.7%) of the patients undergoing PVP, respectively, both of which were also judged to be equivalent to those of BKP. The pain score improved in those undergoing PVP, and this improvement was maintained during a one-year follow-up. Of the 206 patients who had difficulty walking at baseline, 156 had restored walking at discharge.Conclusions: PVP was shown to be a safe and effective treatment, even in elderly patients with painful osteoporotic vertebral fractures.
Highlights
There has been no consensus on the optimal therapy for isolated superior mesenteric arterial dissection (ISMAD).
ISMAD patients can be treated conservatively if there are no signs of an aneurysm, ulcer-like projection (ULP), and mesenteric ischemia.
When an aneurysm or ULP sign exists, endovascular stenting was able to preserve superior mesenteric artery blood flow with improvement of the dissection.
A 90-year-old female presented with poor right groin wound healing due to lymphorrhea and infection following a surgical cutdown procedure for arterial revascularization. Although negative pressure wound therapy (NPWT) and inguinal lymphadenectomy were performed, infection and lymphorrhea did not heal. Lymphangiography via a right inguinal lymph node revealed lymphatic leakage in the wound. Intranodal glue embolization (IGE) was performed by injecting 0.6 mL of 33% n-butyl-2 cyanoacrylate (NBCA)-lipiodol mixture. Additionally, the presence of glue in an open wound was directly confirmed in this case. After embolization, lymphorrhea ceased, and the wound healed completely. No lymphorrhea recurrence or complications were observed for 6 months. This case suggests that IGE could be an effective treatment for groin lymphorrhea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
