[Noninvasive assessment of myocardial functional reserves in young women with nonspecific aortoarteritis and aortic arch syndrome]. / Neinvazivnaia otsenka funktsional'nykh rezervov miokarda u molodykh zhenshchin s nespetsificheskim aortoarteritom i sindromom dugi aorty.

AIM: To study functional myocardial reserve in patients with nonspecific aortic arteritis (NAA) and aortic arch syndrome (AAS). MATERIAL AND METHODS: Myocardial functional reserve was studied in 42 patients with NAA using ECG, spiroveloergometry, section and doppler echocardiography, radionuclide ventriculography. Healthy nonsportswomen served control. RESULTS: ECG revealed left ventricular hypertrophy in most of the patients, spiroveloergometry showed low exercise tolerance in many NAA patients. Echocardiography detected differences in patients vs controls by diastolic thickness of the interventricular septum, left ventricular myocardial mass and aortic diameter. As shown by radionuclide ventriculography, 75% of NAA patients with predominant affection of the aortic arch branches had disturbed ventricular function. CONCLUSION: 84% of NAA patients with AAS at veloergometry exhibited signs of transitory myocardial ischemia. Hemodynamic changes at exercise demonstrated low coronary reserve. Silent myocardial ischemia is typical for NAA patients.

[Ultrasonic diagnosis in the surgical treatment of angiodysplasias of the lower extremities]. / Ul'trazvukovaia diagnostika v khirurgicheskom lechenii angiodisplazii nizhnikh konechnostei.

An experience with examination and surgical treatment of 156 patients with angiodysplasia of lower extremities shows that the ultrasonic location and dopplerography are highly informative methods of diagnosis of this disease. The orthostatic probe (the Valsalva test effect) allows the spread of angiodysplasia (suprafascial or subfascial) to be determined. The adequate strategy and volume of surgery can be chosen correctly. These methods of examination being noninvasive and easy makes them helpful for the objective assessment of the effectiveness of the surgical procedures and control of further treatment.

[Diagnosis and treatment of liver echinococcosis complicated by cysto-biliary fistula]. / Diagnostika i lechenie ékhinokokkoza pecheni, oslozhnennogo tsistobiliarnym svishchom.

890 patients with echinococcosis of the liver were operated during 1976-1992. Complicated forms of the disease were li detected in 222 (24.9%) patients, among them 141 (15.8%) patients with cysto-biliary fistulas. Ultrasonography examination and endoscopic retrograde cholangiography were regarded as the most informative methods of preoperative diagnosis of cysto-biliary fistulas. Three-stage management was worked out. The usage of laser, plasmatic scalpel and ultrasound of low frequency substantially contributed to improvement of the results of treatment of these patients.

[The echocardiographic indices of patients with tetralogy of Fallot before and after the suturing of subclavian-pulmonary anastomoses]. / Ekhokardiograficheskie pokazateli u bol'nykh s tetradoi Fallo do i posle nalozheniia podkliuchichno-legochnykh anastomozov.

Echocardiography was made in 69 patients with Fallot's tetrad before and 2 weeks-15 years after forming subclavian-pulmonary anastomosis (SPA). By the anastomosis function the patients were divided into 2 groups. 47 patients with satisfactory function of the anastomosis 3.2+ -1.06 years after the operation comprised group 1. 22 patients of group 2 had marked cyanotic syndrome due to thrombosis of the anastomosis 9.45 + -2.45 years after surgery. Echocardiography in Fallot's tetrad patients before and after SPA specified anatomic components of the defect, size of the left heart and results of the operation.

[Problems of diagnosis and surgical tactics in the treatment of occlusion of the abdominal aorta]. / Voprosy diagnostiki i khirurgicheskoi taktiki v lechenii okkliuzii briushnoi aorty.

Ultrasonic examination in occlusion of the abdominal aorta and its visceral branches is effective in 87.7% of cases. In combined lesions of the aorta and its visceral branches the authors suggest one-stage reconstructive operations to correct the blood flow. The mortality rate in such cases reduced by 6.76%.
