Case Reports[Neuroradiologic intervention in intracranial arteriovenous malformations].
23 patients with intracranial arteriovenous malformations and durafistulas were embolized. 13 underwent embolization with polyvinylalcohol and silk threads as the only means of therapy, while six were also operated on, and four received radiation after considerable reduction of the nidus had been achieved. No death or major complications occurred in these patients. The authors considered the embolization to be successful in all cases.

The position of a central venous catheter has to be controlled. As a supplement to radiography of the chest the position of the catheter tip can be documented by means of ECG. The ECG is recorded with the catheter tip functioning as one of the electrodes. ⋯ The position of the catheter tip correlates with the morphology of the P-wave. An ECG recording performed during insertion of the catheter can be used to achieve correct positioning of the catheter to start with and thereby reduce the frequency of having to replace wrongly positioned catheters. Intraoperatively the ECG recording is a practical method of achieving correct and extracardial placement of the catheter tip.
