Serie interventional ultrasound: Ultrasound-guided interventional radiology procedures on veins

Although ultrasound-guided interventional procedures have resulted in great advances in many fields of medicine, this approach has revolutionized endovascular procedures. This paper aims to review the basic principles to develop a strategy to follow in ultrasound-guided treatments of varices in the lower limbs, as well as to provide a brief overview of the main endovenous techniques available nowadays. We divide these techniques into those that use catheters to occlude straight saphenous axes (thermal / non-thermal ablation) and other options, such as foam sclerotherapy, which can be used in all types of varices, even in those originating in the pelvis.
