[False aneurysms of the vascular anastomoses after reconstructive operations on the aorta and arteries of the lower extremities].

The authors have performed an analysis of examination and surgical treatment of false aneurysms of vascular anastomoses (34) in 29 patients after reconstructive operations on the aorto-iliac and femoro-popliteal segments. This late complication was found to develop in 3.3% of the patients operated upon.

[Recurrence of ischemia of the lower limbs in patients with functioning vascular prosthesis].

On the basis of experience in surgical treatment of 242 patients with recurrent ischemia of the lower limbs in late periods after operations on the aorta and peripheral arteries, the authors singled out a group of patients (44) with unobstructed but hemodynamically incompetent vascular prostheses. Their hemodynamic changes were caused by stenosis of the vascular anastomoses and shunts or by the development of occlusions of arteries beyond the reconstructed segments. The authors relate all these complications to the prethrombotic stage of late reocclusions and insist in their recognition before the development of thrombosis of the vascular prosthesis.

[Experimental validation of a method for the early diagnosis of the infection of vascular prostheses using 99m-TC-labelled leukocytes].

Experiments on 9 dogs were staged for a study of a method of early diagnosis of infectivity of vascular prostheses of the abdominal aorta with the help of 99m-Tc-labelled leukocytes. A sterile synthetic vascular prosthesis was used for prosthetics of the abdominal aorta in the 1st control group of animals, a prosthesis, previously infected with St. aureus, was used in the 2nd group, a sterile prosthesis with its subsequent infecting by i.

[Obturator shunting in suppuration of vascular prostheses].

An experience with using obturatory shunts in 10 patients with suppurations of vascular prostheses after reconstructive operations on the aorto-iliac segment for its occlusive lesion is presented. The authors have come to a conclusion that extra-anatomical shunting through the closing inlet of the pelvis when combined with resection or removal of the infected vascular prosthesis, local and general antibacterial therapy is an effective method of treatment of the pathology in question. The modified method of shunting facilitates performing the operation in most critical patients.

[Experience in the clinical use of vein grafts from the umbilical cord of newborn infants for arterioplasty].

The work analyzes the first experience of clinical using the xenograft from the neonatal umbilical cord vein for different kinds of arterial plasty in chronic occlusion diseases. For a year 19 patients were operated. In most cases the femoropopliteal shunting or prosthetics above or under the knee joint was made.
