Methods of interventional radiology have achieved a significant importance for the treatment of acute iliac artery occlusion if either local or general clinical controindications preexclude routine surgical means of vessel repair. The newly developed balloon-expandable metal mesh vascular endoprosthesis is shown to accomplish percutaneously a definitive reconstruction of heavily diseased iliac artery vessel segments which very well compares with the hemodynamic and morphologic aspect of surgical treatment such as thrombectomy combined with TEA or bypass surgery. Both, short and long-term results one year after the implantation of two balloon-expandable metallic vascular stents reflect a much higher efficacy in functional treatment of iliac artery related claudication than a routine percutaneous transluminal angioplasty alone. In addition, it is shown that local lysis based on a standard protocol of selective intrathrombus instillation of urokinase helps to clear totally clogged iliac arteries.
