[Aortocoronary bypass with 10 years' follow-up. Apropos of 183 cases].

Between 1970 and 1972, 183 patients were admitted to the CMC Foch (Pr D. Guilmet) for saphenous vein aorto-coronary bypass surgery. Ten years later a questionnaire was sent to the patient and his cardiologist and the two replies were analysed.

[Calcifying obstructive disease of the descending thoracic aorta].

The authors present the first surgically treated case of calcifying obstructive disease of the descending thoracic aorta. The diagnosis was based upon the coexistence of an aortic isthmus coarctation syndrome together with massive calcifications seen by chest X-ray. The aetiology remains uncertain but the authors tend in favour of an atheromatous aetiology.

[Surgical treatment of thoracic and thoraco-abdominal aneurysms involving the Adamkiewicz's artery. Usefulness of deep hypothermia (author's transl)].

The authors present a new surgical technique for the treatment of thoracic and thoraco-abdominal aneurysms involving the artery of the lumbar enlargement (Adamkiewicz's artery) at its point of origin. In two patients the aortic segment giving birth to the artery was accurately located by angiography and re-impaired under deep hypothermia and extracorporeal circulation.

[Value of surgical approach to the vertebral artery in its extra-cranial segment. A case of aneurysm of the vertebral artery in C3 (author's transl)].

Long considered dangerous, surgical treatment of lesions of the vertebral artery in its extra-cranial course, may be viewed in parallel with angiographic techniques. Approach to the vertebral artery in its different segments, pre-operative arteriographic assessment, are discussed, and operative indications only mentioned. An aneurysm of the vertebral artery in C2-C3 was treated by exclusion and restoration of continuity by a sub-clavian vertebral vein graft in C1-C2.
