[Critical ischemia of the diabetic patient].
BACKGROUND
Critical ischemia of the lower limbs is the final result of diabetic arteriopathy. The surgeon is more and more forced to choose between amputation  d emblée  and the attempt to revascularization in very old patients and in deficient general conditions. Shall we point out some principle to address our strategy?


METHODS
To answer this question we reviewed retrospectively our surgical choices and the results obtained during two years, from January 1997 to December 1998 (medium follow-up 11.3 months), at the Emergency Division of the  Cannizzaro  Hospital of Catania. In this period 143 diabetic patients were selected by our ambulatory. Of these, nineteen had a critical lower limb ischemia and therefore were submitted to a revascularization and/or amputation. All the revascularized patients were controlled by Doppler-sonography immediately after operation and then daily, till their discharge. Controls were done at the first, third, sixth month and after one year, except for patients who complained a new objective or subjective ischemic symptomatology.


RESULTS
The primary patency rate was 84.2% and the secondary patency rate was 89.4%. The amputation rate due to the procedure failure was 5%. The complications were three: two graft infections (10.5%) and one early thrombosis of a femoro-popliteal bypass graft, due to technical defect (5.2%). Perioperative mortality rate was 15.7%.


CONCLUSIONS
These results, if related with those reported in the letterature about amputations, are in favour of the attempt to revascularization.
