Nevertheless, the efficacy of their concomitant treatments is still controversial for a decade. In the guidelines of the Japanese Society of Phlebology, concomitant phlebectomy of tributary varicose veins with ETA is described that it is not recommended officially. In our hospital, RFA without concomitant phlebectomy of tributary varicose veins accounts for 74% of the RFA cases and it shows a relatively higher percentage than other institutions in Japan. The data of RFA without concomitant phlebectomy of tributary varicose veins are evenly matched in RFA with concomitant treatments in our data concerning recurrence, remnants, endovenous heat-induced thrombosis (EHIT), and complications. This article provides the conclusion that it would be acceptable to perform isolated RFA compared to RFA with concomitant phlebectomy or foam sclerotherapy of tributary varicose veins in short- and mid-term periods.

This paper examines the outcomes of revascularization in Japanese CLTI patients and emphasizes the benefits of tailored management. Post-hoc analysis of the bypass versus angioplasty in severe ischemia of the leg (BASIL)-1 trial validated the use of the Global Limb Anatomic Staging System for predicting the outcomes of endovascular therapy (EVT) but not bypass surgery (BS).

Revascularization improved the quality of life, but benefits declined over time, especially in non-ambulatory and older patients on dialysis. Surgical reconstruction is better for preserving ambulation.
