[Radiologically-guided dilatation in arterial stenosis of transplanted kidney].

Stenosis of the artery of a transplanted kidney is a grave complication of the posttransplanation period. Two method are applied for correction of the disease: reconstructive operation and radiologically-guided endovascular dilatation (RED). The primary method of choice is RED of the stenosis.

[Radiologic assessment of heart transplantation].

Twenty patients were examined before and after orthotopic transplantation of the heart. The significance of x-ray examination of donors to ascertain brain death was demonstrated. The possibility of x-ray examination of recipients is analyzed.

[Role of computerized tomography in stenoses and other diseases of the trachea and main bronchi].

Fifty-one patients with stenosis of the upper portion of the tracheobronchial tree of various origins were examined; the sensitivity of computer-aided tomography (CAT) in the diagnosis of stenoses of the trachea and the main bronchi was found to be 95.83%, specificity 98.31%, and accuracy 93.

[Diagnosis of tumors of the trachea and main bronchi by computerized tomography].

A total of 104 patients with tumors of the upper portions of the tracheobronchial tree were examined. The tumors were malignant in 66 cases (53 primary and 13 secondary ones) and benign in 38 cases. The sensitivity of CT in the diagnosis of blastomas of the trachea and the main bronchi made up 96.

[State of coronary circulation and results of 24-hour ECG monitoring in patients with refractory angina pectoris].

The paper compares the data of selective coronary angiography and 24-hour monitoring in 39 patients with refractory angina pectoris. Transient ST-segment changes were revealed in 79% of the patients, ST-segment depression occurring in 54%, ST-segment elevation in 46%, T-wave inversion in 38%. A combination of ST-T interval changes and occurrence of ventricular premature contraction was found in a third of the examinees.

[Possibilities of computerized tomography in destructive bone changes in patients with polypous rhinosinusopathy].

The authors made a CT investigation of 15 patients (11 men and 4 women) suffering from polypous rhinosinusopathy. Thirteen patients prior to it underwent polypectomy of the nose. Ophthalmocele was observed in 7 patients.

[Transcutaneous transcatheter use of laser recanalization of coronary arteries in patients with ischemic heart disease].

The paper discusses the potential possibility and effectiveness of X-ray endovascular laser recanalization (ELR) of the coronary arteries in order to treat coronary atherosclerosis in patients with coronary heart disease. The intervention was performed in 4 patients (into the anterior interventricular artery in 3 and into the right coronary artery in 1). In 3 of 4 cases, X-ray ELR proved to be successful, in one case the intervention failed due to technological reasons.

[Total sequestration of the labyrinth].

At present total sequestration of the labyrinth in the case of purulent epitympanitis and cholesteatoma is a rare pathology. This paper describes data from the literature and two observations by the present authors. They offer an efficient method for arresting labyrinthectomy-induced liquorrhea by means of a flap of the lip mucous membrane.

[Computed tomography in the diagnosis of pathological states of the lumbar diaphragm. 2: diseases of the diaphragm].

CT potentialities in the diagnosis of diaphragmatic diseases were considered. CT provides valuable information in relaxations of the diaphragm and diaphragmitides, permitting the detection of infiltration of the diaphragm by a tumor, retroperitoneal fibrosis, diaphragmatic cysts, Bochdalek's hernia, and hernias of the esophageal opening. An algorithm for investigation of patients with suspected diaphragmatic pathological conditions was proposed.

[Computed tomography in the diagnosis of pathological states of the lumbar diaphragm. 1: general data. Developmental defects and traumatic disorders].

CT was employed for investigation of 94 patients with pathological changes of the diaphragm. Congenital defects and unilateral aplasia of the diaphragm were observed in 5 of them. A new symptom of a pathological line of the diaphragm was recognized, characteristic for this type of patients.

[Radiologically-guided vascular prosthesis after laser recanalization of occlusive lesions of the blood vessels of the lower limbs].

The article deals with the first clinical experience in radiologically-guided prosthetics after laser recanalization of occluded vessels of the lower limbs in 20 patients. The method was introduced into clinical practice after applying separately the methods of radiologically-guided endovascular prosthetics and laser recanalization with subsequent dilatation and experimental substantiation on dogs with artificially created chronic occlusions of the femoral artery. The first results are promising, although the true place of the method in sparing treatment of vessels will be ascertained after rich clinical experience is accumulated and the late-term results studied.

[Radioendovascular prosthesis of renal arteries in patients with renovascular hypertension].

A high percentage of restenoses after roentgenovascular dilatation of the renal arteries laid the basis of a search for new therapeutic methods for these patients. Experiments on implantation of nitinol spiral endoprostheses showed their ability for long-term permeability of renal arteries, not causing their thrombosis and intimal spreading, destruction of formed elements of the blood, change in plasma proteins. Morphological investigations have shown rapid formation (during 14 days) of connective tissue neointima, covered on the side of the blood flow with the true vascular endothelium (ensuring a nonadhesive surface and laminar blood flow), around the coils of an endoprosthesis.

[The implantation of a nitinol endoprosthesis in treating strictures and atresias of the uterine cervical canal].

The paper is concerned with the description of the first experience in a new method of roentgen endoprosthetics of the cervical canal of the uterus using a nitinol spiral prosthesis. The spiral has a shape memory effect. Prostheses were implanted to 13 patients with strictures or atresia of the cervical canal after bougienage for a period of 193 days.

[Computerized tomography in the diagnosis of heart neoplasms].

Computed tomography (CT) was used to study 56 and 4 patients with primary and secondary cardiac blastomas, respectively. CT allows differentiation between a racemose and dense endocardial tumor, localization of myxoma pedicle, recording its prolapse into the adjacent chamber, identification of extra-, intracardiac and intramyocardial tumor growth as well as changes in adjacent vessels. CT image of cardiac myxoma is similar to a filling defect of diminished density, that of extra-endocardial tumors display polymorphism.
