title: [Use of the Doppler effect in the prevention of accidental intraarterial injection of a sclerosing agent].
abstract: A high degree of safety has been reached in sclerotherapy. The accidental intra-arterial injection of a sclerosant is considered to be a rare but serious complication. After mentioning the importance of clinical examination the author considers the import of the ultra-sound method to diagnostics and the prevention of some complications in sclerotherapy. He recalls the dangerous zones and situations, and clearly demonstrates the precision of the Doppler which indicates arterial vessels. It is important to interpret correctly the language of the ultra-sound investigation, and to evaluate the spontaneous signals from the arteries by exploring the sounds produced by venous circulation with the various available techniques. The discussion involves 76 patients examined by the Doppler before sclerosis. No complications were observed, although in 17 cases there were arterioles close to the varices or microvaries to be injected. This proves the importance of the Doppler in the daily practice of all angiologists.
