Experience in treating patients with diabetes and anastomotic false aneurysm after reconstructive interventions in the aortic-femoral segment

Abstract

The purpose of the work isto analyze and improve the results of treatment of patients with diabetes and anastomotic false aneurysm (FA) after reconstructive interventions. Materials and methods. The results of diagnostic examinations in 79 patients with 93 false anastomotic aneurysms were analyzed, the criteria of wound complication (hematoma, infiltrate), patency of shunts, bleeding, heart attack, stroke were evaluated. Among the patients there were 75 (94.9 %) men and 4 (5.1 %) women aged 40—75 years (mean age — (58.4 ± 2.9) years). 69 (87.3 %) patients underwent surgery for atherosclerotic lesions of the pelvic vessels and lower extremities, including 43 (54.4 %) patients with diabetes, 3 (3.8 %) — for abdominal aortic aneurysm, 4 (5.1 %) — after vascular injury, 3 (3.8%) — due to nonspecific aortic arteritis. A total of 79 patients underwent 93 reconstructive interventions. Results and discussion. The time of onset of clinical symptoms (pain, pulsation), which give reason to suspect the occurrence of FA, ranged from 8 days to 19 years: in 15 patients — less than 1 year, in 59 — up to 10 years, in 5 — up to 20 years. The average duration of FA formation after surgery is 62.5 months. The absence of pathological changes in the area of the proximal anastomosis and the presence of adequate outflow pathways in most cases allow us to limit the reconstruction of the distal anastomosis. Conclusions. Early diagnosis and surgical tactics for false anastomotic aneurysms in patients with diabetes can prevent complications and improve the results of surgical treatment. The optimal type of surgery for false aneurysms is their removal with re-prosthesis of the affected segment, which allows to save the limb and the patient's life. The use of modern pharmacological agents allows to reduce the progression of atherosclerosis, which is the main cause of false aneurysms. Dynamic ultrasound monitoring is required for patients who have undergone reconstructive vascular surgery.
