Comparison of drug eluting balloon angioplasty to infrapopliteal artery critical lesions with or without additional pedal artery angioplasty in patients with diabetes mellitus and critical limb ischemia.

Our study shows that additional BTA angioplasty to BTK intervention may improve the primary patency rate and have higher event free rate, which slightly missed the margin of statistically significance. RBC decreased significantly more in BTA group compared to BTK group, which reflected that the outcome of intervention is better with additional BTA angioplasty.
