[Treatment of experimental broncho-pleural fistula with myoplasty]. / Leczenie doswiadczalnej przetoki oskrzelowo-oplucnowej metoda myoplastyki.

Surgical experiment of closing broncho-pleural fistula by muscle flap from the chest wall was conducted on the sheep model. The procedure was completed in two stages. During the first thoracotomy the middle lobe of the right lung was removed. In the second stage the vascularised muscle flap of the latissimus dorsi was inserted in the pleural space and stitched onto the bronchi stump closing broncho-pleural fistula. Microscopic investigation of lung, bronchus and muscle tissue performed after each step of procedure showed the inflammatory process primarily and the regression of it after the second stage. Well vascularised muscle flap is the best tissue for repair of broncho-pleural fistula.

[Clinical picture of acute myocardial infarction depending on the use of pharmacologic treatment schemes]. / Obraz kliniczny swiezego zawalu serca w zaleznosci od zastosowanego schematu leczenia farmakologicznego.

The aim of the work was a retrospective comparison of the clinical course of acute myocardial infarction depending on the applied schema of pharmacological treatment: streptokinase, heparin, antiplatelet drugs. The analysis included 409 patients (261 men and 148 women aged 31-85 years; mean age 61 years). Twelve-lead ECG records were analysed: 24 hours, 48 hours, 72 hours, 7 days and 14 days after the onset of the disease. The sum of ST segment elevations, sum of Q wave amplitude and the sum of R wave amplitude in the leads showing signs of infarction were taken into account. The mean was calculated from the highest values of AspAT and AlAT. The haemodynamic, arrhythmic and other early and late complications occurring during the treatment were subjected to analysis; the per cent index of deaths in each group was also calculated. In the patients treated with streptokinase, in comparison to the patients treated with heparin and antiplatelet drugs, earliest stabilization was observed of the ECG pattern in the form of: reduction of ST segment elevation, reduction of R wave height, and formation of a stable Q wave. AspAT and AlAT values were highest in the group of patients treated with streptokinase in relation to the remaining groups of patients. Arrhythmic and haemodynamic complications occurred less frequently in the patients treated with streptokinase and heparin than in those treated with antiplatelet drugs. On the other hand, late and other early complications were observed less frequently in the patients treated with antiplatelet drugs. The mortality during hospitalization period was similar in individual groups of patients, being 7.2% for the patients treated with streptokinase, 7.5% for those treated with antiplatelet drugs, and 9% for those treated with heparin.
