Mitral valve replacement for small pediatric patients is technically difficult because of the small annulus and requires some technical ideas. The chimney technique is useful for supra-annular mitral valve replacement. We describe a paediatric case of early re-replacement owing to pannus formation after mitral valve replacement using the chimney technique.
To achieve less-invasive for varicose vein surgery, we performed foam sclerotherapy alone for residual incompetent tributaries after truncal vein surgery without phlebectomy. This study investigated 239 consecutive patients (140 women; mean age, 66.2±0.7 years) with varicose veins between April 2018 and December 2020. We performed endovenous therapy for truncal veins without phlebectomy, then sclerotherapy for incompetent tributary varicosities and the below-knee great saphenous vein (BKGSV) after 2-3 weeks. Among the 239 cases, 229 were treated with radiofrequency ablation and 10 with cyanoacrylate closure. No adverse events of nerve injury or thromboembolism were encounterd.Reflux in the BKGSV after endovenous therapy persisted in 67.0% (150/224). Sclerotherapy was performed once in 174 cases, two or more in 35, and not at all in 30. Mean follow-up period was 13.2±0.6 months (range, 0-32 months).
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.
