Combined fibrinolytic therapy for critical limb ischemia in patients with diabetic foot syndrome

Aim. To propose a pathogenetically substantiated infusion therapy based on the results of a comprehensive evaluation of lower limb ischemia in diabetic foot syndrome. Methods. Energetic Doppler sonography of the blood vessels of the lower extremities in its distal part and electrothermometry in 32 patients with diabetic foot syndrome and critical limb ischemia was conducted in addition to the general clinical imaging studies (radiography, ultrasonography in the «gray scale» mode). Considering the obtained data the treatment strategy in these patients (conservative or surgical) was determined together with a physician-endocrinologist. Results. Presented is an example of tactics formation for conservative infusion therapy of a patient with diabetes mellitus, which is complicated by the diabetic foot syndrome with critical limb ischemia. Compiled was an individual treatment algorithm. At the initial stage crystalloid solutions (slow drip, followed by urination stimulation) were administered. Next prescribed were vitamins from group B (cyanocobalamin 0.25 mg and pyridoxine 50 mg) in order to regulate the metabolism of key neuromediators and amino acids. The complex of treatment included the nonsteroidal anti-inflammatory drug diclofenac (25 mg). This was followed by administration of dextran solutions (reopolyglukine), in combination with an antiplatelet solution (pentoxifylline). At the final stage of therapy administered was prostaglandin E1 (alprostadil, 3-4 infusions per course). Local treatment: osmotic agents were applied to the right foot as semi-alcohol compresses to relieve swelling, improve microcirculation and promote closure of the fistulas. After the conducted treatment noted was an improvement in general condition, pain symptoms subsided, the fistula closed, the soft tissue on the foot had no signs of inflammation. Recovery of the parameters of microcirculation signify the relief of arterial and venous stasis. Conclusion. This treatment scheme will make it possible to improve the course of the disease, reduce the time of treatment and disability of patients, will also improve their quality of life.

Despite the success in treatment, currently 30.0% of patients with diabetic foot syndrome (DFS) still undergo high amputations with a mortality rate of up to 54.0–68.0 %. The causes of high low limb amputations in 28.0 % of patients are infection, and in 46.0 % – arterial insufficiency in the stage of critical limb ischemia.Objective: to improve the results of patients treatment by reducing the number of high amputations of the lower extremities, reducing the occurrence of complications and deaths of the disease.Materials and methods. To study the results of treatment of patients with DFS, they were divided into two comparison groups and two main groups. From 1982 to 2019, the frequency of amputations, mainly at the hip level, was 71.0 % (177 amputations in 248 patients). These patients formed the first comparison group of observations. The second comparison group (1988–1994) included 58.3 % of patients in whom amputations were performed according to more stringent indications (157 amputations in 269 patients). The first main group of observations (1995–2013) included 9.9 % of patients with DFS who were amputated only for wet gangrene, incurable critical limb ischemia, and infection with a systemic inflammatory response (130 amputations out of 1312 patients). In ischemia with preserved blood flow through the deep artery of the thigh, amputation of the lower leg was performed in a sequential-two-flap method with removal of the soleus muscle. Amputations were completed with the imposition of drainage removable muscle-fascial sutures. The second main group (2014) consisted of 11.4 % of patients who underwent amputations only for sepsis or wet gangrene (124 amputations in 1083 patients). The difference between the second main group and the first was the division of the high amputation intervention into 2 stages.Results. Comparison of the treatment results in the main groups and in the comparison groups revealed a 6-fold decrease in the number of high amputations (from 64.6 to 10.69 %) and a significant improvement in the main quality indicators. This concerns a 6-fold decrease in mortality, which was a consequence of the introduction of a two-stage tactic for high amputation treatment of the most severe patients and the limitation of indications for amputation of the hip. Using of removable drainage muscle-fascial sutures decreased postoperative wound complications from 51.9 to 13.0 %, and the number of re-amputations decreased in 17th times.Conclusion. Amputation of the lower extremities for irreversible critical limb ischemia can be performed with a decrease in TcP02 of the stitched stump tissues to no more than 30 mm Hg. Preserving the knee joint improves the possibilities of prosthetics, which allows older diabetics to lead an active life. Methods of performing parallel- or sequential-two-flap high amputation improve the conditions for cutting out racquet-shaped wound flaps, which provides free displacement of the soft tissues of the stump connected by removable drainage sutures.

Peripheral blood mononuclear cells (PBMNCs) are reported to prevent major amputation and healing in no-option critical limb ischemia (NO-CLI). The aim of this study is to evaluate PBMNC treatment in comparison to standard treatment in NO-CLI patients with diabetic foot ulcers (DFUs). The study included 76 NO-CLI patients admitted to our centers because of CLI with DFUs. All patients were treated with the same standard care (control group), but 38 patients were also treated with autologous PBMNC implants. Major amputations, overall mortality, and number of healed patients were evaluated as the primary endpoint. Only 4 out 38 amputations (10.5%) were observed in the PBMNC group, while 15 out of 38 amputations (39.5%) were recorded in the control group (p = 0.0037). The Kaplan–Meier curves and the log-rank test results showed a significantly lower amputation rate in the PBMNCs group vs. the control group (p = 0.000). At two years follow-up, nearly 80% of the PBMNCs group was still alive vs. only 20% of the control group (p = 0.000). In the PBMNC group, 33 patients healed (86.6%) while only one patient healed in the control group (p = 0.000). PBMNCs showed a positive clinical outcome at two years follow-up in patients with DFUs and NO-CLI, significantly reducing the amputation rate and improving survival and wound healing. According to our study results, intramuscular and peri-lesional injection of autologous PBMNCs could prevent amputations in NO-CLI diabetic patients.
