Chronic Clinical Findings after Rheocarna® Therapy in a Chronic Limb-threatening Ischemia Patient with Inframalleolar Lesions.

ABSTRACT

An 87-year-old man was referred to our hospital for non-healing ulcers on the right third, fourth, and fifth toes. The patient was diagnosed with chronic limb-threatening ischemia. Pre-treatment angiography of the right lower extremity revealed inframalleolar lesions. We failed to perform endovascular treatment because of severe calcification. Therefore, we treated the patient with a novel low-density lipoprotein apheresis device (Rheocarna®; Kaneka, Osaka, Japan). Angiography performed four days after therapy revealed significant improvement in microcirculation. One year after therapy, he managed to avoid major amputation and achieve wound healing. In addition, angiography revealed that the microcirculation was maintained.
