[Prolonged intra-arterial therapy in surgical treatment of patients with critical lower limb ischemia].

In vascular surgery department of V.V. Vakhidov Research Center of Surgery prolonged intraarterial catheter therapy (PIACT) was applied in the treatment of 97 patients with critical lower limbs ischemia. Both routine and special methods of examination were used. Isolated PIACT was performed in 29 patients, PIACT in combination with other operations--in 68 patients (lumbar sympathectomy--51, microsurgical transplantation of greater omentum--9, arterialisation of venous system--8). Good and satisfactory results were achieved in 82.4% patients, limb amputations were performed in 17.6% patients. PIACT is most effective only in combination with other surgical methods. Use of PIACT in acute limb ischemia is not recommended.
