Figure 5: Shockwave lithoplasty (Eccentric calcifications and subintimal pathway). (a) Middle sized occlusion of the superficial femoral artery (Fontaine stage IV) with moderate collateralization. (b) Solid calcifications prevent endoluminal passage but by use of a reentry device (Outback, Cordis Inc.) the true lumen can be reentered via a subintimal pathway. (c) After balloon angioplasty an insufficient lumen can be achieved. (d) After placing a long self-expanding stent two compression zones are still present. (e) Native image shows the massive calcifications partly compressing the stent. (f) After additional lithoplasty, the distal compression could be resolved while the proximal compression was only partly improved
