3.2. Group B (Control Group)
necrotic lesions, ulcerations, venous by-pass, necrosis
ULCERATION, ULCERATIONS, NECROSIS
This group consisted of nine people, including six men and three women aged 59–78 years. Three people had necrosis of the toes, three patients had ulceration of the foot or lower leg, one person had multiple necrotic lesions and ulcerations, and two others had necrosis in the toe amputation ligation (one case ending in a major amputation).Prior to saline administration, four patients had an ‘in situ’ femoropopliteal venous by-pass and five patients had an ‘in situ’ femoropopliteal venous by-pass with profundoplasty and/or iliac axis debridement.Lesion healing in up to 12 weeks occurred in six patients (66.67% of the group), and above 12 weeks, there were no such cases.The ABI increased from values in the range of 0.20–0.55 to values in the range of 0.45–0.85, by an average of 0.14, i.e., 0.11 less than in the gene therapy group.TcPO2 increased from values in the range of 25–49 mmHg to values in the range of 52–85 mmHg, by an average of 27.1 mmHg, i.e., 3.3 mmHg less than in the gene therapy group.The rest of the data on the amount of classical and endovascular procedures performed in the patients, the patency of the grafts immediately after the procedures and after 3 months, and the presence of stationary ulceration are shown in
