Abstract
PTA(percutanous transluminal angioplasty) is the
treatment of choice in patients with infrapopliteal occlusive
disease who typically present with CLI(critical limb ischaemia).
With recent advances in technology, long and multiple stenotic
and occlusive lesions can be treated successfully. This minimally
invasive procedure carries a lower morbidity and mortality and
shorter hospital stay compared with surgery and should be the
first treatment option in all patients with CLI who would
otherwise be offered distal bypass surgery or amputation, as
failure rarely precludes surgery. Clinical success is superior to
angiographic patency and in the majority of cases repeat
angioplasty can be performed if there is recurrence of ischaemic
symptoms and signs.ABI(Ankle-Brachial Index)is a good
indexand investigation. Infrapopliteal PTA can also be performed
after femoral angioplasty or bypass surgery, to improve outflow
and hence patency of the proximally treated segment.
