RESUMO
Objective To evaluate the mid-term follow-up of the pereutaneous angioplasty of the occlusive acrtoiliac artery diseases.Methods The data of 30 patients who had distal abdominal aorta and bi-lateral iliac artery stenosis or occlusion and treated by percutaneous angioplasty were retrospectively reviewed.They are 24 males and 6 females,aged from 35 to 75 years (average 55 ± 10 years). The interventional procedures include wire-guided canalization,thrembolysis,balloon angioplasty and stents implantation.They were followed up by telephone,letter or visiting after discharged.Results Twenty-six patients with aarto-iliac are revascularized successfully.Three cases failed.Of them,one failed because only one side of iliac artery and aorta were successfully canalized while the eontralateral not,one failed to revascularize both the aorta and the iliac artery,the other one failed due to the ihac rupture and replaced by WallGraft implantation.Two cases had distal thrombosis during the procedure.One case was amputated due to the aggravated isebemia of the right lower extremity after the revascularization failed.Twenty-seven cases were followed uo after 1 to 112 months,averaged (41±9) months.One case showed that the iliac artery was uncanalized after 6 months.One case showed bilateral iliac artery occlusion during 25 months follow-up and re-occluded 3 months after balloon angioplasty and finally had stent implanation in bilateral iliac artery.The other patients had no aggravated symptom of recurrence.Conclusion The percutaneous angioplasty is a good choice for occlusive aorto-iliac artery disease,showing good recovery during mid-term follow-up.
