The present invention provides methods and systems for placing stent systems at vascular bifurcations. The systems include a main branch stent having a side opening, optionally including a side structure, with radiopaque fluoroscopic markers about the periphery of the opening. The stent system further includes a side branch stent having radiopaque markers near at least end thereof. The main branch stent is positioned in the main blood vessel lumen using the markers for proper positioning. After deploying the main branch stent, the side branch stent is positioned through an opening within the side branch. Using the markers on both the main branch stent and the side branch stent, proper alignment and positioning of the two stents relative to each other may be achieved.
