The role of percutaneous transluminal angioplasty in the treatment of critical ischaemia.
In an attempt to establish the overall role played by percutaneous transluminal angioplasty in the treatment of critical ischaemia we studied 101 consecutive patients (110 limbs) who presented to one vascular unit over an 18 month period with this diagnosis. All patients underwent assessment with Doppler waveform analysis and arteriography and decisions about further management were made jointly by the surgical team and vascular radiologist. Results showed that only 24/110 limbs (22%) had lesions that were suitable for treatment with angioplasty alone. In addition one patient underwent angioplasty in conjunction with a distal bypass. Forty-one of the 110 limbs (37%) underwent reconstructive surgery, 18/110 (16%) primary amputation and 26/110 (24%) conservative treatment. Of those 24 limbs undergoing angioplasty, four were technically unsuccessful, and six were technically successful but without clinical improvement and all required alternative treatment. Only 12/110 limbs (11%) showed clinical improvement during their admission following angioplasty. We conclude that although angioplasty can be used successfully to treat critical ischaemia the overall numbers of patients who are suitable for treatment and who gain benefit from it is small.
