- Evaluation of pacemaker wires were performed by comparing Advanced Multiple Beam Equalization Radiography (AMBER) with conventional chest radiography. The scanning equalization technique of the AMBER unit makes it superior to conventional technique in the depiction of different structures in the mediastinum or in the pleural sinuses. So far motion artifacts have not been considered clinically important. The longer exposure time, however, may impair the assessment of pacemaker wires. The motion artifact described may not only make adequate evaluation impossible but may even give a false impression of a lead fracture. The difference between the two systems was significant.

- All vascular injuries occurring at this hospital department over a 5-year period (1987-91) as a result of cardiac catheterization, coronary angiography, or coronary angioplasty (PTCA) and requiring transfusion, surgical consultation, or repair, are reviewed. Such complications may occur late and, to detect cases not apparent from the protocol accompanying every examination, a questionnaire was sent to all surgical clinics in the region asking for details of vascular surgical intervention after angiography. The present review of 4879 examinations disclosed 18 patients with 19 vascular injuries (0.39%); four of them were detected by the questionnaire. The types of injury were: pseudoaneurysm (12), thrombembolic episode (4), and excessive bleeding (3). Of the patients with a vascular complication 11 (61%) were receiving anticoagulation treatment, compared to 10% in the whole series; two others suffered from a coagulopathic state. Catheterization was difficult or severe atherosclerosis was present in three, inadvertent mobilization occurred in one, and unintentional puncture distal to the common femoral artery occurred in two patients. With the increasing use of invasive diagnostic and interventional procedures in cardiovascular diseases, knowledge of the type and frequency of possible complications is important, especially of those that may occur late. In the present study anticoagulation, coagulation disorders, and cardiac catheterization combined with brachial puncture and angiography all predisposed to a vascular complication.

Wrist Arthrography

- The ligaments of the proximal row of carpal bones and the triangular fibrocartilage (TFC) strongly influence the function and stability of the wrist. Injury to the ligaments may result in chronic wrist pain or instability. Wrist arthrography is valuable in the investigation of such damage when surgical intervention is considered and plain radiography is unrewarding. There are also several technical modifications of the standard radiocarpal arthrography available. Owing to the possibility of congenital perforations and degenerative changes in these ligaments the arthrographic findings should be related to the clinical signs and the age of the patient. CT has less diagnostic importance in this respect while MR imaging is an alternative and may become the method of choice. Both these methods have great potential in the evaluation of soft tissues of the wrist other than the TFC.

- The correlation between oesophageal dysfunction (OD), pathologic gastro-oesophageal reflux (GOR), and severity of pulmonary disease was studied in 12 patients with cystic fibrosis (CF). They were interviewed about symptoms of OD and underwent 24-h pH recording in the oesophagus, oesophageal manometry combined with reflux provocation tests, the acid perfusion test, the acid clearance test, lung function tests, and scoring of the chest radiograph. Six of the 12 patients reported symptoms of OD. Abnormal GOR, as shown by 24-h pH monitoring of the oesophagus, was found in eight of them. Altogether 9 of the 12 participants had at least one pathologic oesophagus test result. Results of radiologic examinations of the oesophagus, performed in six patients, were pathologic. The four patients with the best chest radiograph scores and the best lung function had significantly less signs and symptoms of OD and GOR than the other eight patients. We conclude that OD, GOR, and pulmonary disease covariate in CF.

- Forty-two patients undergoing major colonic surgery were assigned at random to receive isoflurane-fentanyl anaesthesia with nitrous oxide in oxygen, propofol-fentanyl anaesthesia with air in oxygen or propofol-fentanyl anaesthesia with nitrous oxide in oxygen. The groups were comparable in demographic data. Atelectases were identified, and the area measured by computerised tomography of the chest 203±69 min after extubation. and oxygenation was determined by arterial blood gas samples taken during operation at 30, 60, 90 and 120 min after extubation and on postoperative days 1, 2 and 3. Atelectases were seen in all three groups with no differences in the mean area between groups. After operation, the effect of 4 l.min−1 of oxygen by nasal catheter on Pao2 was similar in all groups. A significant decrease in PaO2 was found during the first 3 days after surgery, and was also the same in all groups. There was no correlation between area of atelectasis and postoperative PaO2. We conclude there is no difference in the incidence of postoperative atelectasis or oxygenation when using propofol, with or without nitrous oxide or isoflurane.
