[Cervical arteriovenous fistulas after internal jugular catheterization].

The vertebral artery and vein are mostly involved, but other sites exist, especially between the inferior thyroid artery and the internal jugular vein. Five cases were treated in our department. All the fistulas were closed by percutaneous transarterial occlusion with a detachable balloon.

[Aorto-left ventricular discontinuity of infectious origin. Problems of surgical repair].

Aorto-left ventricular discontinuity may result from destruction of the aortic ring in aortic valve endocarditis, making solid implantation of a valvular prosthesis difficult. We believe the best technique to be the insertion of a valved Dacron tube from a noninfected area of the left ventricle to the ascending aorta distal to the coronary ostia, the coronary arteries being reimplanted in the tube. This technique implies a relatively dilated aortic ring and the integrity of the supra-annular aortic wall.
