Comparative Study[Results of multimodal treatment of patients with glial tumors of cerebral hemispheres].
The outcomes of multimodality treatment were assessed in 42 patients with glial tumors of cerebral hemispheres. Radical surgery turned out to be feasible only in 52.4% of patients with high-grade tumor histological variants and 66.7% of patients with low-grade tumors. Five-year survival rates did not improve when a cumulative radiation dose was increased from 33 to 70 Gy and amount to 21.4 and 73.8% in high- and low-grade tumours, respectively.

Le Fort's fractures of maxillary bones are referred to grave injuries that require an accurate and urgent diagnosis. A total of 70 patients with different variants of such fractures were examined. ⋯ The injuries with all signs of Le Fort's fractures of two and even three types predominated, asymmetric injuries were rather frequent. Panoramic sonography with the patient in a modified position helped specify the volume and extension of the injury to the facial bones, but it should be supplemented with linear tomography to detect the injuries of the pterygoid processes of the major bone of the anterior and posterior walls of the maxillary sinuses, of the frontonasal channel opening, of the posterior wall of the frontal sinuses and the anterior cranial fossa structures, the detection of injuries of the pterygoid processes being the key sign in the differential diagnosis of Le Fort fractures.

[The use of digital subtraction angiography in diseases of the arteries of the pelvis and lower limbs].
The diagnostic potentialities of digital subtraction angiography (DSA) in diseases of the pelvic arteries and lower limbs were studied. Intravenous (iv) and intraarterial (ia) DSA were performed in 613 patients, among them were patients with obliterating atherosclerosis and endarteritis, thromboembolism, aneurysms and arteriovenous fistulas. ⋯ This method is economical, well tolerated by patients, permits the intensification of examination of patients with acute and chronic arterial pathology. It can be employed under outpatient conditions and in the early postoperative period.
