[Long-term angiographic surveillance of operated ascending aorta dissections]

Systematic angiographic surveillance of ascending aorta dissections demonstrates the frequency and diversity of often asymptomatic anatomical lesions. A study in 10 previously operated cases enabled differentiation with the prosthetic tube, usually implanted in the ascending aorta, of proximal postoperative lesions (residual dissection, aortic incompetence, aneurysm) which may require further surgery in the more or less long term, and distal lesions (the usual persistence of a false channel in type I dissections) which are generally left untouched.
