Abstract
Peripheral percutaneous transluminal angioplasty may restore sufficient distal blood flow for ulcer healing in selected patients with severe multi-segmental vessel lesions. PTA can also be used in combination with surgery to reduce the length of a bypass and to avoid a composite bypass.
The present study included 30 diabetic patients with critical arterial occlusive disease affecting the infrgenicular and inframalleolar arteries underwent percutaneous transluminal angioplasty (PTA) for treatment of critical lower limb ischaemic and diabetic lesions. The patients were selected according to inclusion criteria.
CTA was performed in all patients to quantify the extent of disease in below-knee and pedal arteries. The assessment of technique was based on patients clinical observation and necessary tests (ABPI and TBI measurement, duplex and angiographic evaluation).
Technical success (resulting in less than 50% residual stenosis) after dilatation is achieved in 27/30 patients and failure in 3/30 patients.
Clinical success defined as healing of resistant ulcer or amputation wound, relived rest pain or even when it is transformed to claudication and improvement in ABPI and TPI measurement are evaluated pre-PTA and post- PTA immediately, at 1 month, 3 months. There was a significant improvement in duplex and ABPI measurement post- PTA.
Limb salvage is considered with avoidance of major amputation, but minor amputation as toe or trans- metatarsal amputation, if it is carried out in a limb, such limb is considered to be salvaged.
