[Efficacy of two-level infrainguinal reconstructions in treatment of chronic critical lower limb ischaemia].

Aim: to determine the scope of infrainguinal revascularization of the limb in patients with multilevel lesions of arteries in chronic critical lower limb ischaemia (CCLLI).

Material And Methods: A retrospective analysis of graft patency and limb salvage included a total of 76 patients undergoing a total of 78 bypass procedures consisting of: 1) two-level infrainguinal reconstructions (n = 35), 2) femoral-tibial (n = 36) and femoralplantar (n 7) bypass procedures. All patients had an isolated segment, of the popliteal artery in a combination with bifurcation arterial occlusive disease.

[Application of preparation endotelon in complex treatment of chronic arterial insufficiency of lower extremities].

The results of treatment of 43 patients with chronic ischemia of extremities with application of preparation endotelon were summarized. Stable positive effect, preserved during 2-4 month was noted in 34 patients. Lowering of regional venous pressure, at average for the first week by (1.

[Topographical and anatomic substantiation of sheath block of the brachial plexus].

The authors have studied the anatomic peculiarities of the fascial case of the plexus in an experiment on 60 preparations of the brachial plexus as well as the ways of diffusion of the solution along the case making use of various methods of block. It has been shown that the fascial case forms a closed space determining the diffusion of the solution on a considerable way along the plexus. The main way of diffusion of the anaesthetic solution are the paravasal loose connective tissue structures.
