Iliac Angioplasty Or Stenting For Limb Salvage: Prognostic Factors.

Aim: The aim of this study is to determine prognostic factors of limb salvage after iliac angioplasty ± stenting for chronic limbthreatening ischemia patients with iliac artery disease alone or with concomitant other lesion (femoro-popliteal or infrapopliteal disease). Methods: In this prospective interventional study, 32 patients with symptomatic steno-occlusive iliac artery disease treated by balloon angioplasty ± stenting. Patients’ data & comorbidities are collected and they are followed up for 1 month after iliac artery angioplasty ± stenting for above the knee amputation. Results: Comparison of data for final outcomes of limb salvage versus above-the- knee amputation showed that amputation is more likely with the increase in age with p value 0.035. Moreover, medical comorbidities were of no statistical significance regarding amputation however, angiographic characteristics and TASC classification were statistically significant regarding limb salvage. All the patients with total iliac artery occlusion (5 patients) underwent above-the-knee amputation within 1 month following the intervention while the limb was salvaged in patients with iliac artery stenosis with p value < 0.001. In addition, limbs with diseased both CIA and EIA were more prone to above-the-knee amputation than limbs with diseased CIA only with p value 0.009. State of profunda femoris artery was a statistically significant prognostic factor for limb salvage as limbs with diseased PFA were more prone to above-the-knee amputation than limbs with healthy PFA with p value 0.023. Limbs with TASC D were more prone to above-the- knee amputation than TASC A, B, C with p value < 0.001. Limb salvage was more reported in patients who underwent iliac artery angioplasty & stenting than in patients who underwent angioplasty only with p value 0.002. Conclusion: Above-the-knee amputation 30 days post iliac artery angioplasty ± stenting is significantly associated with increasing age, total iliac artery occlusion, concomitant CIA & EIA lesions, diseased PFA, TASC D lesions & in patients who underwent iliac artery angioplasty only than in patients who underwent angioplasty & stenting.
