The healing process is based on vein thrombosis, fibrosis, and venous atrophy. Saphenofemoral interruption makes venous occlusion easier and prevents potential thrombotic complications and recurrence by recanalization. DUS monitoring makes possible to follow-up the thrombus involution and perform early retreatment. The 808-nm endosaphenous laser should be mainly applied to veins of <10 mm in diameter.
The short saphenous vein is more and more often held responsible for the onset and development of varicose conditions and post-operative recurrence. In order to perform complete posterior saphenectomy account must be taken of the frequent anatomical variations in the outflow of this vein. A method of intra-operative phlebography of the short saphenous vein has been developed. The results confirm the high rate of the anatomical variations. Intra-operative phlebography facilitates complete posterior saphenectomy without negative effects in terms of surgical trauma and cosmetic results, thanks to the new technical developments.
Hypotrophic valve damage seems to be prevalent in patients with varicose veins of the lower limbs. Valve cusp hypotrophy may be present in early disease though some normal cusps can be found in advanced disease. When preoperative echographic visualization of cusps is doubtful, intraoperative angioscopy plays the main role in the diagnosis of venous valve disease before and during external valvuloplasty.
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.
