OBJECTIVES: to determine management of patients with critical lower limb ischaemia (CLI) from first presentation to investigation and treatment. DESIGN: prospective study of critical ischaemia patients. METHODS: one-year prospective survey (May 2000-May 2001). Follow-up 3-15 months. RESULTS: some 873 arterial cases presented, 134 patients had CLI. Of the latter 49% were men, 30% diabetic, the median age was 81 years. Only 15 (24%) of 62 cases were referred to outpatients as urgent. Patients waited a median of 25 days (range 1-100) to be seen in outpatients, and had symptoms for a median of 8 weeks. Treatment was conservative for 70 patients, and 11 primary amputations, six secondary amputations, and 62 revascularisation procedures (34 operative, 28 percutaneous transluminal angioplasty) were performed. At follow-up (3-15 months, median 9 months), rates of major amputation and death were 12 and 27% respectively. Significantly more diabetics underwent major amputation (p < 0.02) than non diabetics. Patients presenting with ulceration or gangrene were at greater risk of death than those with rest pain alone (p < 0.01). CONCLUSION: patients with CLI often have symptoms for many weeks before being seen by a specialist, and 76% are referred as non-urgent cases. This compares with patients with suspected malignant disease in the U.K. who are required to be seen within 2 weeks.
