[Results of diabetic foot surgical treatment in gerontological patients].

The experience in surgical treatment of 1200 patients with an ischemic form of diabetic foot syndrome is analyzed. Surgical reconstruction of the major arteries was performed in 338 (28%) patients including reconstructive surgeries on the aorto-iliac-femoral segment--70 (21%), distal reconstructions--246 (73%), extra-anatomic reconstructions--22 (6%) patients. In distal reconstructions autovein in situ was used in 94, reversed autovein--in 82, and PTFE grafts--in 70 patients. Good results were achieved in 235 (69%), satisfactory--in 57 (17%) patients. Early thrombosis was revealed in 46 (14%) patients, femoral amputation was performed in 36 (10.6%) patients, 5 (1.4%) patients died.

[Treatment of pyonecrotic complications in diabetic macroangiopathy].

Results of treatment of 104 patients aged from 47 to 82 years with stage IV talocrural ischemia (by A.V. Pokrovsky) due to diabetic macroangiopathy were analyzed. Significant depression of immune status was revealed: number of T- and B-lymphocytes decreased by 40-50%, phagocytosis--by 65-75%, number of immunoglobulins--by 25-30%. The majority of the patients had endotoxicosis, hypercoagulation and hyperlipidemia; the correction of it by hemosorption and plasmapheresis was performed depending on the disease stage. 90 patients underwent surgery. Reconstruction in aorto-ileo-femoral zone was performed in 57 patients (in 34--with good results), in femoro-popliteo-femoral zone--in 33 patients (in 19--with good results). The "Gore-Tex" grafts were the plastic material for reconstruction, but autovein in situ was also used in femoro-popliteal zone.

[Autovenous bypass in situ in distal occlusions of the arteries].

In patients with bad distal bed and blood flow along the bypass two functioning venous collaterals were left with the diameter less than 1 mm, with the blood flow volume 100-150 ml/min one collateral was left, if the volume was 150-200 ml/min it was not necessary to make an arterio-venous output. One-two functioning collaterals left did not influence the volume and linear velocity of blood flow along the bypass and the parameters of hemodynamics. 78 patients (91%) were discharged with the functioning bypasses and decreased ischemia. A year later thrombosis of the bypass was noted in 6 (14%) of 43 follow-up patients, stepwise liquidation of one or two collaterals was fulfilled in 5 patients due to a more than 1 mm dilatation. Prognostically the blood flow in the zone of a distal anastomosis less than 100 ml/min is thought to be most critical.

[Surgical treatment of middle-aged and elderly patients with chronic ischemia and distal occlusions].

Operative treatment for critical ischemia was performed on 346 elderly and senile patients. An assessment of the distal bed and outflow pathways has shown the conditions for the reconstruction of the vessels to be unfavorable in 257 (74%) patients. Femoro-proximal-popliteal shunts were made in 82 patients with good effect in 74 of them. Femoro-distal-popliteal and tibial shunts were made in 62 patients with good effect in 52. In 12 patients out of 20 with the isolated plasty of the profound femoral artery better blood flow and arrest of pains in rest were noted. Lumbar sympathectomy was performed in 142 (41%) patients, in 46 of them it was combined with continuous intraarterial infusion and in 20 patients--in combination with the rotor osteotrepanation on the femur and shin. Good results after sympathectomy were noted in 102 patients.

[Status of lymphatic vessels, lymph flow and lymph toxicity in patients with obliterating arterial diseases of the lower extremities].

The condition of the lymph vessels, the lymph flow, and the toxicity of peripheral lymph were studied in 46 patients with obliterating diseases of the arteries of the lower limbs. The results of the study showed the severity of the destructive changes in the peripheral lymphatic system to be directly dependent on the severity of the arterial ischemia of the limb. Block of the lymphatic system, deceleration of the lymph flow, and changes in the lymph vessels themselves lead to deterioration of the tissue drainage function and intensification of regional endotoxicosis. In view of which correction of the peripheral lymphatic system should be included in the complex of measures for the treatment of patients with obliterating diseases of the lower limb arteries.
