Aim: The aim of this study was to evaluate the results of percutaneous transluminal balloon angioplasty in 
patients suffering from infragenicular arterial diseases in patients with critical lower limb ischaemia. 
Patients and methods: From March 2008 to June 2011, 32 patients with critical lower limb ischaemia (40 
infragenicular lesions) were treated by percutaneous transluminal balloon angioplasty, clinical results and 
patency were evaluated by means of symptoms assessement, Ankle Brachial Pressure Index (ABPI) and 
duplex scanning at discharge and at 1, 3, 6, 12 and 24 months after angioplasty. 
Results: 40 lower limb arterial lesions (Infragenicular) in 32 patients presented with critical lower limb 
ischaemia were treated by balloon angioplasty, the age of the patients range from 50 to 72 years (mean age 61 
years), the period of follow up range from 12 to 24 months, the primary patency rates were 95%, 87.5%, 80%, 
70% and 65% at 1 month, 3 months, 6 months, 12 months and 24 months respectively, while the limb salvage 
rates were 95%, 95%, 90%, 85% and 80% at 1 month, 3 months, 6 months, 12 months and 24 months 
respectively. 
Conclusion: Primary infragenicular balloon angioplasty for limb salvage in patients presented with critical 
lower limb ischaemia represents an efficacious method to improve wound healing if present and to improve 
rest pain taking into consideration the fragile nature and co-morbidities in such patients.
