[Diagnosis of chronic massive pulmonary thromboembolism in elderly patients]. / Diagnostika chronickej masívnej tromboembólie pl'úcnice u chorých v starsom veku.

Chronic massive thromboembolism of the pulmonary artery is an occlusion of the major branches of the pulmonary artery which develops as a result of repeated embolisms, as a result of non-dissolution and organizing of a thrombus or retrograde growth of a thrombus. The authors observed four elderly patients with chronic massive pulmonary embolization. In their clinical picture dominated progressing dyspnoea and signs of right heart failure. In the diagnosis perfusion scan of the lungs and pulmoangiographic examination plays an important part as they revealed even unilateral absence of pulmonary circulation. This examination was stimulated by weaker respiration at the site of the lacking perfusion in a portion of the lungs.

[Reconstructive operations in our clinical data]. / Rekonstrukcné operácie v nasom klinickom materiáli.

The authors present the results of reconstructive vascular operations performed during the period from 1990 to 1994. According to the criteria of the European Vascular Surgery Council the lowest patency was recorded in the distal type of femoropopliteal bypasses in the lower extremities. They emphasize the necessity to apply the "Graft Surveillance Programme" in vascular consultation centre. (Tab. 2, Ref. 7.).
