    Description / Table of Contents: Résumé On a réalisé des phlébographies intra-osseuses et mesuré la pression intra-médullaire au niveau de la métaphyse chez 55 patients atteints d'une maladie de Perthes unilatérale. L'irruption du produit opaque dans la diaphyse constitue le signe le plus important au cours de la phlébographie osseuse métaphysaire. Elle s'accompagne d'une élévation de la pression intramédullaire, ce qui traduit l'existence d'une congestion veineuse métaphysaire. Comme cette congestion s'observe aussi bien au stade de sclérose qu'à celui de segmentation, elle ne peut préjuger de la gravité de la maladie, selon la classification de Catterall [1]. La congestion veineuse peut jouer un rôle dans la pathogénie de la maladie de Perthes, mais le pronostic relève probablement de facteurs différents.
    Notes: Summary Intraosseus venography and measurement of intramedullary pressure have been carried out in the metaphyses of 55 patients with unilateral Perthes' disease. Flow of the opaque medium into the diaphysis is the most important finding in intraosseous venography of the metaphysis. This was related to a rise of intramedullary pressure which indicates the presence of venous congestion within the metaphysis. While such congestion was seen both in the sclerotic stage and the segmentation stage, it was not related to the severity of Perthes' disease as judged by Catterall's [1] classification. Such venous congestion could be relevant to the pathogenesis of Perthes' disease, but there are probably different factors which determine the prognosis.

    Notes: Abstract The association between intracranial aneurysms and arteriovenous malformations (AVMs) is well documented. Recent advances in the understanding of the haemodynamics of this association encourage an aggressive approach to these aneurysms. However, the pathophysiology of these aneurysms is not fully understood and a strategy for their management has not been established. We describe seven patients, with eight aneurysms, on the feeding arteries of AVMs. The aneurysms could be divided into those located 1. proximally on the superficial feeding artery (type I; 4 aneurysms); 2. distally on the superficial feeding artery (type II; 3 aneurysms); and 3. on the deep feeding artery (type III; 1 aneurysm). All aneurysms were treated by the endovascular procedure prior to, or simultaneously with, treatment of the AVM, using detachable coils or liquid embolic material. All aneurysms were obliterated successfully, with no adverse events. Each patient further received treatment of the AVM. None of the patients suffered intracranial haemorrhage after treatment for the aneurysms. Based on our experiences, we discuss the indications for this approach for each type of aneurysm. We believe endovascular treatment could be an important alternative for treatment of aneurysms associated with AVMs, thus reducing the risk of haemorrhage.
