Treatment of a patient (#7) with bilateral buttock claudication and iliac stenoses.

<p>(a) Digital subtraction angiography showing the sheath retrogradely advanced to the common iliac artery. Stenoses of the external and internal iliac arteries are visible at their respective origins (arrows). (b) Results of percutaneous transluminal angioplasty of the external iliac artery with a 7 mm balloon and the internal iliac artery with a 4 mm balloon catheter. CIA = Common Iliac Artery. EIA = External Iliac Artery. IIA = Internal Iliac Artery.</p

Treatment of a patient.

<p>(a) Digital subtraction angiography of the left common iliac artery showing a proximal stenosis of the internal iliac artery (IIA), with sub-optimal filling of subsequent branches. (b) Result after treatment with 5 and 6 mm percutaneous transluminal angioplasty, showing residual origin stenosis of the IIA of more than 30%. (c) Subsequent stent placement (Palmaz 6 mm diameter) reduced the stenosis grade to less than 30%, and provided adequate distal blood flow. (d) Overlay of Figure c showing branches of mentioned vessels, guide wire position (white dotted line) and placed stent (white mesh). CIA = Common Iliac Artery. EIA = External Iliac Artery. IIA = Internal Iliac Artery.</p
