[Complications of intravenous digital subtraction angiography--results in 500 patients].

500 patients were studied respectively for complications of intravenous digital subtraction angiography (IV-DSA) performed with non-ionic contrast media, using a central venous injection technique. In 21 patients (4.2%) during or shortly after the procedure 23 systemic, 1 neurologic, and 7 local complications occurred. In addition 1 patient developed acute renal failure 26 hours after the IV-DSA, whereas 4 patients later showed on thromboses of the catheterised vein. No permanent neurologic or systemic complications and severe allergic reactions were seen.

[Complications of brachiocephalic catheter angiography using a non-ionic contrast medium].

In 713 patients 749 catheter-arteriographies of aortic-arch and cerebral vessels were performed using non-ionic contrast media. The patients were examined either with DSA or conventional film techniques. In 80 examinations of 76 patients complications or side-effects were noted, which resolved completely within one hour in 69 cases, showed a duration up to 7 days in 6 cases, and persisted longer than 7 days in 5 patients. Neurological complications were seen in 6.4% of the studies. There was no death. Patients, who received anti-hypertensive drugs before or during angiography and patients with a pathological angiogram had a significantly higher complication-rate. The rising number of patients with atherosclerotic cerebrovascular disease showed an unfavorable effect upon the overall complication-rate. The use of a non-ionic contrast medium did not drastically lower the rate of neurological complications.

[Significance of the colon contrast enema in evaluating the importance of rectosigmoid polyps].

The radiological appearance of mostly broad-based polyps in the rectosigmoid was studied in 35 patients. In all patients the diagnosis was histologically confirmed after surgical treatment. Conclusions on the histological tumour status could not be drawn either from surface structure, broadness of base and retraction of base, or from the base/height ratio. Stenosing growth, however, was seen relatively more often with carcinomas than with benign lesions. The discovery and identification of five carcinomas having a size of up to 2 cm illustrates the need for complete removal and histological processing of even seemingly negligible residues of polypous processes in the rectosigmoid.
