[Inferior Vena Cava Suprarenal Filter Implantation].

The paper analyzes indications for, frequency, safety, and efficiency of inferior vena cava (IVC) suprarenal filter implantation. The study based on the Medline database has indicated that an IVC suprarenal filter should be implanted following very strict indications, such as extensive caval thrombosis; renal vein thrombosis with a thrombus in the IVC; some vascular anomalies; a renal tumor process with a tumor thrombus in the IVC; prevention of pulmonary embolism in pregnant women with deep vein thrombosis; and prior to surgery. IVC suprarenal implantation done as clinically indicated is an effective and safe method to prevent pulmonary embolism.

[Radiation diagnosis of aortic aneurysmal ruptures with formation of anastomoses with the inferior cava and various organs].

The results of radiation diagnostic techniques were analyzed in 29 patients with aortic aneurysmal ruptures with formation of aortic anastomoses. The examination and treatment of 362 patients with abdominal aortic aneurysmal ruptures revealed that 23 (6.35%) patients had anastomoses (aortocaval (n = 15), aortoduodenal (n = 6), aortogastric (n = 1), and aortoureteral (n = 1)). Six patients were observed to have secondary aortointestinal anastomoses occurring after reconstructive vascular surgery. In one patient, abdominal aortic aneurysmal rupture first led to the formation of a primary aortoduodenal anastomosis and some time after surgery a secondary aortointestinal fistula emerged. One out of 113 patients with aortic dissecting aortic aneurysms had an aortopulmonary fistula. Ultrasonography, computed tomography, and angiography were performed in 27, 19, and 14 patients, respectively. Radiation diagnostic techniques revealed fistulas in 9 (31%) out of the 29 patients. The diagnosis of aortic anastomoses presents challenges.

[On validity of the term "chronic" rupture of abdominal aortic aneurysm]. / O pravomernosti termina "khronicheskii" razryv anevrizmy briushnoi aorty.

Treatment of patients with abdominal aortic aneurysms has been analyzed. From 506 patients (265 emergency and 241 elective cases) treated in the department of urent vascular surgery 36 had "chronic disruptions". Validity of this term is discussed. The authors consider the term "repeated disruption" as the most adequate.

[Radiation diagnosis of abdominal aortic aneurysms]. / Luchevaia diagnostika anevrizm briushnogo otdela aorty.

Four hundred and forty seven patients with aneurysms of the abdominal aorta (AAA), including 238 patients with aneurysmal rupture, were admitted to the Research Institute of Emergency Care in 1990 to 2000. The results of studies in 225 patients (ultrasonography in 197, computed tomography in 59, and angiography in 104), including 155 patients with aneurysmal rupture were analyzed. Computed tomography (CT) has proved to be the most accurate technique in the detection and estimation of the size of aneurysms, as well as in the identification of ruptures (83.9%) and inferior to angiography (AG) in the study of involvement of the branches of the abdominal aorta. Ultrasound study (US) ranks below CT in its accuracy (US detects ruptures in 67.8%); however, US surpasses CT and AS in screening, particularly valuable at an admission unit and an intensive care unit, which permits repeated studies. AG has turned out to be the most valid method in identifying the involvement of renal and iliac arteries in aneurysm and in detecting aortocaval anastomoses; yet it is inferior to US and CT (the former revealed rupture and dissection in 18.6% of cases) in solving other diagnostic tasks. Based on the analysis, the optimal sequence of studies in the patients is US, CT, and AG.

[The implantation of a nitinol endoprosthesis in treating strictures and atresias of the uterine cervical canal]. / Implantatsiia nitinolovogo éndoproteza v lechenii striktur i atrezii tservikal'nogo kanala matki.

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. A new canal was formed with further epithelialization within this period. Recurrences after prosthesis removal were unnoticed.

[Surgery of extracranial aneurysms of the carotid and vertebral arteries]. / Khirurgiia ékstrakranial'nykh anevrizm sonnykh i pozvonochnykh arterii.

An analysis of the literature and personal observations of 27 patients with extracranial aneurysms of the arteries enabled the authors to determine clinical symptoms, methods of diagnosis and surgical treatment of the disease. Resection of the aneurysm with suturing the artery defect is recommended as optimal techniques of the operation for posttraumatic aneurysms, resection with the end-to-end anastomosis being proposed for a true aneurysm of the aorta arch branches.
