[Surgical treatment of patients with rupture of abdominal aorto-aneurysm].

Thr experience in surgical treatment of 69 patients with rupture of abdominal aorto-aneurysm was analyzed. Multifactorial statistical analysis was carried out to determine detect influence of different parameters on postoperative lethality. The most significant parameters were initial blood loss (odds ratio (OR) -- 10.4, confidence interval (CI) -- 2.0-37.1, intraoperative hemorrhage (OR=8.5, CI 1.5-27.8), minute diuresis (OR=15,7, CI 1.8- 49.3), location of rupture (OR=12.1, CI 2.0-33.5). Combination of two and more factors led to the most unfavorable prognosis. The proposed algorithm allowed the authors to optimize treatment policy and improve significantly results of surgical treatment of patients with rupture of abdominal aorto-aneurysm: postoperative lethality has decreased from 71.4 to 28.5%.

[Ruptures of abdominal aortic aneurysms. The clinical course and classification].

Surgical treatment of abdominal aortic aneurysm (AAA) ruptures is a matter of great concern in current vascular surgery. The results of surgical treatment of patients presenting with such severe disease could have been improved due to the early and correct diagnosis. The present work is concerned with a study into the characteristic features and causes of the atypical clinical manifestations and the course of AAA ruptures as well as with the development of the classification accessible for practical uses. Later on it would allow to refine the treatment policy for an extremely severe patient group and to define a permissible algorithm of examination in the postoperative time and would favour the early diagnosis of disease. The study is based on an analysis of the clinical course of AAA rupture in 53 patients operated on at the Department of Vascular Surgery. MONIKI. The clinical manifestations were typical in 46 (86.8%) patients. The progressing course of AAA rupture was observed in 21 (39.6%) patients; the disease ran a wave-like course in 17 (32.1%) patients. Stabilization of the condition was marked in 15 (28.3%) cases. In 39 (73.6%) cases, AAA rupture affected the retro-peritoneal space, the free abdominal cavity was affected in 8 (15.1%), the duodenum in 2 (3.8%), the sigmoid intestine in 2 (3.8%), and the inferior vena cava in 2 (3.8%) of cases. The rupture of the posterior wall of the aortic aneurysm was identified in 29 (54.7%), of the lateral wall in 12 (22.6%), and of the anterior wall in 8 (15.1%) patients. Four (7.5%) patients demonstrated aneurysmal rupture of the iliac artery. The clinical manifestations of AAA rupture were marked by polymorphism whereas its course was often masked by other diseases making it difficult to establish the early and correct diagnosis. The difficulties in the diagnosis of AAA ruptures gave rise to a lot of diagnostic errors and late hospitalization to specialized unita.

[Replacement of bone defects with a polyurethane composition with hydroxyapatite high-filling ].

There have been obtained high-filling polyurethane compositions with hydroxyapatite. Compositions with hydroxyapatite and immunomodulator in the polyurethane base acquire better adhesiveness and improved strength characteristics as evidenced by physical-and-clinical studies made. Modal operations are developed in test animals on bone defects replacing that carry a high mechanical load. Histological studies showed that polyuretane-base high-filling polymeric compositions replace the loss of bone fully, stimulate the processes of bone formation, with no negative responses of the osseous tissue noted.

[Eversion carotid endarterectomy: advantages and disadvantages].

A comparative analysis of results of 70 operations fulfilled by the method of classical with autovein plasty of the internal carotid artery (ICA) and of 103 operations by the method of eversion carotid endarterectomy (CEAE) was made. The time of compression of the carotid artery during the eversion CEAE proved to be considerably less (22.5 +/- 6.5) min, than when using the "classical" method (32.5 +/- 5.3) min. In the nearest postoperative period no neurological complications of embologenic genesis or those associated with acute thrombosis of ICA after the eversion CEAE were noted while after the "classical" method they developed in 3 patients and 2 of them died. After the eversion CEAE 1 patients died of myocardial infarction. In remote periods after the "classical" CEAE the restenosis and reocclusions appeared in 6 patients, while after the eversion method--in 3 patients. CEAE fulfilled by the eversion technique is an effective operation reducing the amount of postoperative neurological complications as well as of late restenosis and reocclusions. It can be used without the applying of the internal bypass.

[Differential diagnosis of lobar (regional, segmental) extent pulmonary tuberculosis].

Two hundred and fifteen patients with pulmonary involvement of lobar (regional, segmental) extent were examined. The examination procedure included clinical and laboratory tests, X-ray tomographic study, and computed tomography, bronchoscopy with biopsy, cyto- and histological studies. The nosological diagnosis was established in 96.5% of cases. Differential diagnosis was found to be difficult in 3.5% of cases.

[Plastic repair of the carotid artery in carotid endarterectomy].

The work is based on an analysis of results of 70 carotid endarterectomies performed on 68 patients aged from 43 to 67 years. 53% of the patients were operated upon at the stage of a relative compensation of brain blood circulation. Multiple character of injuries of the brachiocephalic arteries took place in 70.5% of the cases. Plasty of the internal carotid artery is thought by the authors to be necessary by means of using a flap of lyophylized allopericardium, with the diameter of its orifice less than 8 mm.

[Comprehensive radiologic diagnosis of renal neoplasm].

Basing on the results of complex examination of 56 patients with the diagnosis of a renal tumour, including ultrasound scanning, thermography, computed tomography and angiography, the authors consider that examination of a patient should begin from performance of ultrasound sonography and thermography. In case of obscure diagnosis, computed tomography and angiography are to be used.

[Differential diagnosis of pleurisy of tuberculous etiology].

A combined ++clinico-roentgenological+ examination of 367 patients with a pleurisy syndrome was aimed at the study of a potential establishment of the etiologic diagnosis of the disease. Examination comprised the routine tests and findings of various types of biopsy, including pleural biopsy performed within the first two months from disease onset. The etiologic diagnosis of tuberculous pleurisy was most difficult in 96% of the patients who exhibited prolonged and stable maintenance of exudation or, on the contrary, very rapid regression of the pleural exudate without residual changes. Simultaneous morphologic and bacteriological examination of a pleural biopsy specimen contributed to the most efficacious and reliable diagnosis of tuberculous etiology of pleurisy.

[The characteristics of a cholera outbreak in Pushkino District, the Azerbaijan SSR].

The outbreak of cholera in the Pushkino District of the Azerbaijan SSR, caused by the penetration of Vibrio cholerae into the water of the irrigation system, is described. Altogether 2 cholera patients and 39 Vibrio carriers were detected. The etiological agent of this infection was V. cholerae eltor, serovar Ogawa, with typical phenotype characteristics. From all patients and 37 carriers virulent strains and from 2 carriers faintly virulent strains were isolated. In this outbreak family foci were clearly observed, but the transmission of infection through everyday contacts was practically of no importance. The foci with multiple cases were formed due to the action of one transmission factor: contaminated water.
