Remote-sensing and in-situ techniques can be used to model and track the evolution of a Coronal Mass Ejection (CME) from its solar eruption to its interplanetary manifestation (ICME), including the travel through the low corona and the solar wind (SW). The synergy from combining these different observational techniques have produced very important progresses in our understanding of these astrophysical objects, with important consequences on Sun-Earth connection and space weather. In particular, major advances have been obtained on identifying different substructures inside ICMEs, some times forming multiple flux ropes. Recent results obtained from these combined techniques will be given in this presentation, with special focus on new insights about magnetic properties and expansion of ICMEs, and physical processes that can take place during the interaction ICME-SW and ICME-ICME.
