Summary
Aim. The objective of the study was to analyze the results of endovascular treatment of iliac artery occlusion depending on the type of atherosclerotic lesions according to the TASC II classification.
Materials and methods. 46 patients with occlusion of the common iliac arteries and/or external arteries were operated in our clinic from 2008 to 2012. Based on the angio CT/angiogram results, the changes have been classified as type B (20), C (16) and D (10) according to the TASC II classification. The group included 37 male and 9 female aged 41-85 years, mean age 66.15ys.
Results. Following successful percutaneous iliac artery angioplasty stent was implanted in 37 patients, whilst in 9 cases no stent was applied. Significant complications were observed in five patients: unstable coronary heart disease - 1 case, pseudoaneurysm of femoral artery 1 case, peripheral arterial embolism- 2 cases. A case of iatrogenic external iliac artery rupture with haemorrhage into the retroperitoneal space was noted. This patient required open surgery. All patients have been followed up to one year. At that time primary assisted patency was noted to be 100%.
Conclusions. 1. All TASC types of chronic iliac artery occlusion can be successfully managed using intravascular methods, with acceptable complication and conversion to open surgery rate. 2. Midterm results (annual primary assisted patency) have been very satisfactory. 3. Long-term patency of iliac artery angioplasty still require further investigation.
