Complex percutaneous coronary interventions are very common in everyday practice. This type of interventions could not be performed without knowledge of technical aspects of new generation drug eluting stents (DES). There are growing number of publications that new generation DES is more successful in treatment of complex lesions then old generation with better short and long term outcome.1 Randomized controlled trials on results of percutaneous interventions in complex lesions are crucial in establishing of appropriate treatment for this very challenging group of patients. Results from interventional registries such as Swedish SCAAR registry are very valuable for every day practice. [ABSTRACT FROM AUTHOR]

Percutaneous interventions on lesions in aortoiliac localization have been in focus of interest from the very beginning of interventions because of anatomic suitability and very good short and long-term results. New guidelines from European Society of Cardiology on Peripheral Artery Disease1 published in 2017 made changes in categorization of lesions by abandoning TASC II classification. Endovascular approach has I C recommendation for first choice treatment of occlusive lesions up to 5 cm in length. More complex lesions should be considered for endovascular- first strategy in patients with severe comorbidities. In general, endovascular treatment of peripheral artery disease in aortoiliac localization has a very important role after optimal medicament treatment and supervised exercise training.
