Combined non-invasive diagnostics of deep vein thrombosis of the lower extremities.

Application of a combined non-invasive diagnostic approach to screening examination of a high-risk group of patients made it possible to detect phlebothrombosis on 34 lower extremities in 31 patients with absent clinical manifestations of the disease. Combined use of Doppler ultrasound flowmetry and occlusive venous plethysmography increases the accuracy of the diagnosis of deep vein thrombosis of the lower extremities up to 96%.

Adult

[Determination of the viability of a patient's intestine by using laser doppler flowmetry during surgery].

Intraoperative determination of the viability of the intestine by means of laser Doppler flow measurement was conducted in 26 patients. The method proved to be highly effective, made it possible to judge most objectively the degree of changes in blood flow in various parts of the intestine in a short time and correct them subsequently during the operation, and considerably reduced the possibility of the development of postoperative complications due to inadequate appraisal of the degree of vascularization of the mobilized segments of the small and large intestine which are prepared for the formation of the anastomosis.

Aged

[Experience in the use of a pneumo-obturator in patients with colostomy].

The authors were able to prevent uncontrollable discharge of intestinal contents in 70 patients with colostomy by means of a pneumo-obturator of an original design. Its advantages over magnetic obturating devices were revealed: the simple and light design, hygienic properties, short adaptation period, and no need for implantation of a foreign body into the tissues surrounding the colostomy. Sixty-four patients use the device regularly and are able to retain feces of any consistency. No complications have been noted. The pneumo-obturator may therefore be used for creating a new method for controllable evacuation of the intestine.

Adult

[Peripheral hemodynamics at various stages of deep vein thrombosis of the legs].

A study of 46 patients at different stages of deep-vein thrombosis of the legs, using venous-occlusion plethysmography, doppler ultrasonic flowmetry and radiopaque phlebography, has identified structural and functional mechanisms compensating venous outflow for clinically inapparent nonocclusive thrombosis, acute occlusion of a major venous trunk and post-thrombotic disease.

Acute Disease

[Pathogenesis of paralytic intestinal obstruction in peritonitis].

The author believes that the vascular spasm does not play any part in the occurrence of functional ileus in peritonitis. Humoral factors, such as the loss of electrolytes and serotonin, which is of a specific mediatory effect upon the intestine in particular, are by far more important. It seems that some other humoral factors, e.g. bacterial toxins and endotoxins, formed during the inflammatory process, play their part too. The article is published for purposes of discussion in connection with the paper by Yu. L. Shal'kov. a coll. (Vestnik Khirurgii, 1976, N 4, p. 55).

Hemodynamics

[Use of low-frequency currents in the treatment of severe intestinal paralysis].

Low-frequency impulse currents (Bernar current) are suggested for treatment of paralytic intestinal obstruction. The method was used in 108 patients, in whom the cause of paresis was as follows: acute purulent peritonitis, pancreatitis, operations on the abdominal aorta and its branches. In 102 patients the stimulation proved to be effective, in 6 cases of progressive purulent peritonitis no effect was gained. In a number of patients the procedure had to be repeated during 2--3 days. Generally, diadynamic currents were employed in a complex with other measures: syphon enema, paranephral blockade, cholinergics, etc. A grave cardiac pathology and oncological diseases are considered as contraindications.

Electric Stimulation

[10-year experience with heart stimulation in atrioventricular heart block].

Data covering 177 cases of the atrioventricular block where cardiostimulation was effected by using Soviet-made batch-produced electrocardiostimulators are analyzed. The largest group included patients 50 to 70 years old (71 per cent). In 47 per cent of the cases the atrioventricular block stemmed from ischemic heart disease. As indications for cardiostimulation served the Morgagni-Adams-Stocks syndrome and a well-marked circulatory insufficiency. The hospital lethality comprised 15.8 per cent. The death was caused by acute cardio-pulmonary incompetence, thromboembolism of the pulmonary artery and myocardial infarction. Among complications secondary to cardiostimulation figure suppuration of the operating wound, disturbed integrity of the myocardial electrodes and a premature exhaustion of the cardiostimulators reserves. From among 130 patients kept under observation the duration of cardiostimulation comprised: up to 1-year--in 20.7, from 1 to 3 years--in 26.1, from 3 to 5 years--in 20.7, from 5 to 10 years--in 1m.7 and over 10 years--in 14.8 per cent.
