Successful application of conditioned culture medium for the treatment of a chronic wound of an amputation stump: a clinical case

Background: Amputation of the lower extremities is a necessary procedure to save a patient with critical arterial and neurotrophic disorders in the lower extremities. The amputation stump-related complications develop in many patients with diabetes mellitus (up to 40% of the total population). Clinical case description: Patient Yu., 64 years old, was admitted on October 19, 21 for an outpatient treatment of purulent-necrotic wounds of the amputation stump of the right lower limb. А high amputation was performed on September 24, 2021 due to thrombosis of the femoral-tibial bypass, installed on September 08, 2021 (bypassing below the knee joint gap with a Vascutek 7 mm synthetic prosthesis on the right) and the development of critical ischemia of the right lower limb with necrosis of the distal phalanges of the right foot toes. The wound was assessed according to the Bates-Jensen scale (BJ) and examined according to the developed protocol. The wound treatment was carried out according to an individual plan using a conditioned culture medium from mesenchymal stem cells (CM-MSCs), which stimulates angiogenesis and improves remodeling and recovery in the wound area. CM-MSC application made it possible to reduce the healing time and achieve a scarless closure of the tissue defect. Conclusion: The use of CM-MSC can be an effective method for healing a purulent-necrotic postoperative wound resulting from amputation of a limb in patients with critical ischemia of the lower extremities.
