MPFF treatment limited the postsclerotherapy inflammation in surrounding microvascular network, suggesting that MPFF may prevent undesirable secondary effects of the procedure in this animal model. This study warrants further investigation for its use in clinical conditions.

Objective This study assessed the outcomes and impact on the quality of life following one-step outpatient radiofrequency ablation (RFA) and ultrasound guided foam sclerotherapy (USGFS) for large reflux with varicosities in the great saphenous vein (GSV). Design Prospective, single-centre, analytical cohort. Materials and Methods Thirty symptomatic patients having reflux in the GSV and varicosities (CEAP C3 to C6) were treated with RFA and USGFS simultaneously, in a single-step procedure, from March 2016 to December 2016. They were followed up at 1 week, 6 months, 1 and 3 years. Clinical outcomes, changes in the Quality of Life (QOL) questionnaires SF-36™, VCSS and AVVQ, evolutive vein occlusion rates were assessed by duplex ultrasound, and ulcer closure was checked. Results The sample was divided into two groups: (Group 1) GSV diameter ≥13.0 mm (median 19.0 [14–24]), 17 subjects, and (Group 2) GSV diameter ≤12.9 mm (median 10.3 [10–12]), 16 subjects. No major adverse event was observed, and the postoperative minor adverse event rates were similar between the two groups. A significant improvement was observed in VCSS and AVVQ from the preoperative levels to the sixth month and the third-year follow-up. Twelve of 13 ulcers had healed at 1 year and remained closed until 3 years. The entire sample had a significant increase in all short form 36 domains, except for mental health in the Group 2 (GSV ≥ 13.0 mm). Overall first week occlusion rate for the whole sample was 90.9% and 69.7% at the 3-year follow-up. No difference in occlusion rate was observed between the two groups at any time. Conclusion Exclusively outpatient combined techniques were safe and feasible in this study with no major adverse events, despite the large diameters of the GSV or ulcer presence. Within 3 years, both diameter groups showed equivalent improvement in all QOL parameters, satisfactory axial occlusion, and maintained ulcer closure.

O aneurisma da artéria poplítea é o mais frequente dos aneurismas periféricos verdadeiros. Embora seja assintomático, apresenta complicações isquêmicas por embolia ou trombose. A correção deste aneurisma pode ser cirúrgica convencional, com técnica e prognóstico bem estabelecidos, ou endovascular, técnica inovadora e menos invasiva. A reperfusão do saco aneurismático excluído, apesar de rara, está relacionada à intensa circulação colateral. Relatamos um caso de aneurisma de poplítea, que após dois anos de exclusão apresentou fluxo no saco aneurismático com sintomatologia, sendo tratado por técnica endovacular alternativa.

Objectives This study describes an alternative carotid bifurcation endarterectomy technique in which the external carotid artery is used as a suture patch. Methods Charts of ten patients with atherosclerotic carotid stenosis that were treated using the neobulb technique between 2002 and 2019 were reviewed. Results No major surgical adverse event was observed in the postoperative assessments. No postoperative common or internal carotid stenosis was observed in the mid- or long-term follow-up. Conclusions The neobulb technique allows carotid endarterectomy closure without a synthetic or venous patch, using the external carotid artery as an autologous patch, while preserving distal flow into the external carotid artery branches.
