Intraoperative lobar torsion occurred in 4 of about 2000 patients subjected to thoracotomy. Two of the patients died. Early diagnosis and proper management are of great importance to the outcome. Temporary deflation of the diseased lung by using double lumen endobronchial tube is a potential risk. Early progressive lobar opacity without signs of atelectasis(More)
The cardioangiographic findings in 50 women 40-54 years of age were compared with those of a series of 69 men with infarction recruited from the same catchment area and investigated according to the same principles. Women less often had left ventricular abnormalities than men; this difference was mainly confined to patients with non-Q wave infarctions.(More)
The dimension, contractility, and regional wall motion of the right and left ventricles were scored on the angiograms of 13 patients with arrhythmogenic right ventricular dysplasia. In 10 patients the right ventricle was enlarged, in eight the contractility of the right ventricle was reduced, and in all but one patient there were regional wall motion(More)
AIM To compare the electrophysiological effects of two contrast media (CM), the non-ionic dimer iodixanol and the ionic dimer ioxaglate using computerised dynamic vectorcardiography (VCG) during coronary angiography. METHODS The study was designed as a double-blind, three-period crossover, randomised comparison between iodixanol (320 mg I/ml) and(More)
Coronary sinus flow (CSF) was measured in seven patients with normal coronary arteries (group A) during intracoronary injections of 6 ml arterial blood, 6 ml blood from the coronary sinus, 3 and 6 ml isotonic saline, 3 and 6 ml hypertonic glucose, and 6 ml of a contrast agent (sodium metrizoate). In 10 patients with coronary artery disease (group B), CSF(More)
In 10 patients coronary sinus blood flow (CSBF) was measured during and after injection of iohexol and meglumine-Na-Ca metrizoate in the left coronary artery. Oxygen saturation, lactate concentration and hematocrit were determined in the aorta and coronary sinus before and after a second injection of the two contrast media. The increase in CSBF was(More)
The addition of sodium to nonionic contrast media has reduced the incidence of arrhythmias in animal models. The influence on cardiac function and safety of sodium addition to the nonionic contrast medium iohexol (Omnipaque) was studied in a randomized, double-blind trial in patients undergoing cardioangiography. Fifty-nine patients received iohexol 350 mg(More)
Iohexol (350 mg I/ml) has been compared with meglumine-Na-Ca metrizoate (370 mg I/ml) in selective coronary angiography in 37 adult patients. Iohexol was very well tolerated and resulted in only minor changes in blood pressure and ECG parameters. Changes in blood pressure and R-R interval were significantly more marked following injections of metrizoate(More)
