[Role of visual control during percutaneous sclerosing therapy for soft tissue arteriovenous dysplasias]. / Rol' vizual'nogo kontrolia pri provedenii chreskozhnoi sklerozuruiushchei terapii arterio-venoznykh displazii miagkikh tkanei.

Based on the current concept of the obvious prevalence of surgical treatment of vascular angiodysplasias over low-invasive methods of interventional radiology, the author assesses the capacities of sclerotic therapy performed by the improved visual controlling procedure. By using the well-known semiotics of ultrasound studies of angiodysplasias, the author has made significant methodological amendments to the techniques of sclerotic therapy. The principle of the proposed procedure is a result of complex use of the potentialities of ultrasound visualization and interventional X-ray contrast studies of the vascular system. The procedure was successfully used in 9 patients. It is concluded that that the study of soft tissue angiodysplasias via direct puncture performed under ultrasound guidance, followed by mass contrasting and sclerotic therapy.

[Radiation diagnosis of venous angiodysplasias]. / K voprosu o luchevoi diagnostike venoznykh angiodisplazii.

The paper proposes an original procedure for diagnosing venous dysplasias of different sites. The procedure is based on the analysis of the capacities of currently used invasive and noninvasive techniques of radiation visualization. The practical aspects of conduct of routine studies, their potentialities and shortcomings are outlined. The principle of the proposed procedure is a result of a complex use of the capacities of ultrasound visualization and interventional X-ray contrast studies of the vascular system. The procedure has been successfully used in 8 patients. It is concluded that it is promising to examine venous angiodysplasias by means of direct puncture made under ultrasound guidance, followed by mass contrasting and angiography which may be supplemented by sclerosing therapy.

[The puncture and catheterization of the peripheral vessels using ultrasonic scanning]. / Punktsiia i kateterizatsiia perifericheskikh sosudov s ispol'zovaniem ul'trazvukovogo skanirovaniia.

Having many-year experience with angiographic interventions, the authors examined the potentialities of ultrasonic angioscanning to monitor the implementation of endovascular interventions (EVI). During the study, they developed an original procedure of different EVI with intraoperative ultrasonic monitoring, refined the ultrasonic semiotics of the procedure, achieved positive results in preventing possible complications. The authors made indications for the procedure and rational ways of its application more concrete. They provide evidence for that the proposed procedure greatly facilitates the performance of different intravascular procedures and reduces the time (or excludes) teleradioscopy, thus lowering the radiation burden on the staff and the patient.

[Computed tomography in refined diagnosis of abdominal aortic aneurysm: comparison of radiation therapies versus surgical outcomes and morphological studies of resected abdominal aortic fragments]. / Komp'iuternaia tomografiia v utochnennoi diagnostike anevrizm briushnoi aorty (po materialam sopostavleniia luchevykh metodov i rezul'tatov khirurgicheskogo i morfologicheskogo issledovanii rezetsirovannykh fragmentov briushnoi aorty).

The results of computed tomography (CT) was compared with ultrasonographic and angiographic findings in 168 patients. All data of radiation diagnosis of abdominal aortic aneurysms (AAA) were compared with those of operations and morphological studies of the resected fragments of the aortic parts changed due to aneurysms. These comparisons provided a detailed characterization of the potentialities of CT performed on a third-generation unit in the presurgical diagnosis of this abnormality. At the same time, detailed XCT findings (semeiotics of AAA and their complications, such infiltration, dissection, and rupture) are given. The study shows benefits of the refined AAA by applying routine CT. The paper gives a diagnostic algorithm of using radiation studies (ultrasonography, CT, angiography) in the diagnosis of AAA. Third-generation CT units widely used in clinical practice are shown to provide necessary and complete information on the magnitude of AAA. This makes it possible to extend the capacities of timely detection of this abnormality and to make a successful surgical intervention.

[Hemodynamics and anaerobic glycolysis during the head-down tilt test in myocarditis patients]. / Gemodinamika i anaérobnyi glikoliz vo vremia antiortostaticheskoi proby u bol'nykh miokarditom.

The analysis is presented of the changes observed in hemodynamics and anaerobic metabolism in myocarditis patients given increasing preload. It is shown that the antiorthostatic test can specify substantial deposition of blood in the lesser or greater circulation. Patients with congestive cardiac insufficiency demonstrate more frequently increased lactate levels in the blood of the coronary sinus and reduced myocardial extraction of lactate.

[Radiologic localization of pancreatic insulinoma]. / Luchevye metody vyiavleniia lokalizatsii insulinom podzheludochnoi zhelezy.

Thirty-one patients with insulinoma of the pancreas verified during operation were examined. The localization of the tumor was detected by ultrasonic examination in 9.7%, by X-ray computed tomography in 38.9%, by angiographic study in 32.1%, and by endoscopic retrograde pancreatocholangiography in 11.1% of cases. Complex use of the methods allowed the localization of the tumor to be determined in 48.4% of cases. The smallest diameter of insulinoma diagnosed during ultrasonic examination and endoscopic retrograde pancreatocholangiography was 1.5 cm, X-ray computed tomography and angiography demonstrated tumors measuring 1.0 cm in diameter. The diagnostic efficacy of the methods increases when the tumor is located in the body and tail of the pancreas. The examination scheme for patients with suspected insulinoma must include ultrasonic study and X-ray computed tomography; when their results are negative angiography must be resorted to.

[The current diagnostic aspects of abdominal aortic aneurysms]. / Sovremennye aspekty diagnostiki anevrizm briushnoi aorty.

Based on diagnostic data in 35 patients with abdominal aortic aneurysm, which were obtained during ultrasonic scan echography, X-ray computed tomography and radioopaque angiography, and on their comparison with intraoperative findings, a diagnostic algorithm for examinations has been developed, which enables errors in the diagnosis to be excluded. The major diagnostic technique for abdominal aortic aneurysms has been found to be X-ray computed tomography which provided no errors in the assessment of the extent of aneurysms and the presence of their complicating components in all 35 patients. In high aneurysms of the abdominal aorta and suspected stenoses in the visceral, renal, and iliac arteries, X-ray computed tomography should be supplemented by radioopaque angiography to clarify the status of aortic branches.
