Backgroundand purpose
To evaluate technical success as a predictor of patency of infrapopliteal angioplasty
in diabetic occlusive lesions.
Patients and methods
This prospective study included 134 cases (critical limb ischemia 100%) that
underwent tibial percutaneous transluminal angioplasty. The end point of follow up was major adverse clinical outcome of the treated segment, which was defined
as healing or clinical failure, that is, need for subsequent intervention such
as endovascular or surgical revascularization or amputation. Follow-up period
was 12 months.
Results
All patients passed uneventful intervention course, and technical success was
reported in 128 (95.5%) cases with minimal complications in ∼36 (26.9%) cases.
There was a significant correlation between major adverse clinical outcome and
major tissue loss, lesion occlusion, subintimal intervention, and complications
(P=0.0001, 0.002, 0.001, and 0.002, respectively).
Conclusion
There are many predictors of patency after infrapopliteal angioplasty in diabetic
occlusive lesions, including patient risk factors. Moreover, type and site of the lesion
and technical success may play a role. However, the most important predictors of
patency are major tissue loss, lesion occlusion, subintimal intervention, or
complications.
