[Plastic surgery of the cervical segment of the esophagus using free autologous transplant of a fragment of the small intestine]. / Plastika sheinogo otdela pishchevoda svobodnym autotransplantatom otrezka tonkoi kishki.

The article presents an experience with the treatment of patients with malignancy of the larynx, laryngopharynx and cervical part of the esophagus with a free autotransplant of the small intestine using a microsurgical technique for reestablishment of the arterial and venous blood circulation in the transplant. On the basis of the postmortem material the advantage of using the initial part of the jejunum were revealed. Experimental studies for the development of the microsurgery technique allowed the authors to propose some methodical means specially for the above operations. Eight operations were performed in the clinic with good functional results.

[Plastic repair of the cervical esophagus using a small intestine autograft in patients with malignant tumors of the larynx and laryngopharynx]. / Plastika sheinogo otdela pishchevoda tonkokishechnym autotransplantatom u bol'nykh so zlokachestvennymi opukholiami gortani i gortanoglotki.

A one-stage procedure to restore the cervical part of the esophagus and laryngopharynx included extended surgery for advanced cancer of the larynx and laryngopharynx and grafting a free revascularized small intestine segment using microvascular technique. Free small intestine transplant proved well-fed by sufficiently large branches of the external carotid artery, and normal venous drainage was retained. The transplant proved biologically best suitable for such type of plastic surgery. Treatment results should be considered promising.

[Combined lesions of the major arteries of the head (clinico-doppleroangiographic correlations)]. / Sochetannye porazheniia magistral'nykh arterii golovy (kliniko-dopleroangiograficheskoe sopostavlenie).

Using Doppler ultrasonography (DUSG) under outpatient conditions multiple combined lesions of the main arteries of the head were found in 127 patients. Comparison of the above results with the findings of cerebral angiography showed a high efficiency of DUSG. In occlusion of the carotid and vertebral arteries the accuracy of the method was 99%, specificity 99%, sensitivity 100%; in stenoses of the internal carotid arteries the respective values were 88, 84, and 95%; in cases of all stenoses of the vertebral arteries they were 93, 92, and 94%. A comparative analysis of the clinical, Doppler and angiographic findings revealed that an increase in the frequency and degree of impairment of the main arteries of the head correlated with an elevated rate of cerebral circulation disorders in several vascular beds.

[Regional blood circulation in the area of the hip joint in patients with various inflammatory rheumatic diseases]. / Regionarnoe krovoobrashchenie v oblasti tazobedrennykh sustavov u bol'nykh s nekotorymi vospalitel'nymi revmatologicheskimi zabolevaniiami.

An analysis of the results of a study of the regional blood circulation in 36 patients with marked pathology of the hip joints of inflammatory nature (rheumatoid arthritis, Bechterew's disease, Reiter's disease) showed a statistically significant increase in transcutaneous oxygen pressure in the projection of the affected joints in unilateral as well as in bilateral pathology. In unilateral pathology there was a significant increase in transcutaneous oxygen pressure, on the surface of the contralateral joint, where pathology was undetectable by routine clinical methods. In the authors' opinion, it could be indicative either of an early stage of the joint involvement or the general reaction of a region under study to an inflammatory process.

[Hemodynamic mechanisms of the functioning of axillofemoral shunts]. / Gemodinamicheskie mekhanizmy funktsionirovaniia podkryl'tsovo-bedrennykh shuntov.

Central and regional hemodynamic parameters were investigated in experimental models of axillofemoral shunts, using electromagnetic flowmetry and electromanometry. Shunt function was shown to be based exclusively on the regional hemodynamic mechanism where blood is "borrowed" from brachycephalic branches of the arch of the aorta. Conditions were identified that contributed to the "stealing" phenomenon in the presence of axillofemoral shunting.
