A 72-year-old woman with chronic myeloid leukemia with T315I mutation in breakpoint cluster region-abelson (BCR-ABL) was treated with ponatinib. During the course of her treatment, chronic limb-threatening ischemia developed in both lower extremities, and the left lower extremity was amputated below the knee at a previous hospital. She was referred to our department for salvage of the right lower extremity. We performed a foot bypass and multidisciplinary treatment of the wound, and achieved epithelialization in about 1 month. The rate of vascular occlusive events with ponatinib has been reported to be high, and we believe that careful monitoring is important during use.
