[False aneurysm appearing 20 years after repair of a subisthmic stenosis of the thoracic aorta (author's transl)].

A patient with atypical subisthmic stenosis of the thoracic aorta was treated by resection of the constriction and reconstruction with a Dacron prosthesis. Clinical recovery lasted for 20 years but the appearance of a false aneurysm required further operative intervention. The etiology of atypical stenoses, the resisting properties of Dacron prostheses, and the formation of false aneurisms are discussed.

[Cardio-respiratory assistance with the extracorporeal membrane oxygenator for massive pulmonary embolism].

A 39 year old pneumectomized patient presents a massive pulmonary embolism, dies within 3 hours and is supported inefficiently by cardiac massage with recurrent mydriasis during 2 hours. At that time, under extracorporeal cardiopulmonary bypass with a membrane oxygenator, the cardiac activity recovers immediatly due to right decompression and coronary perfusion. The patient is conscious within 5 hours. The cardiopulmonary bypass with a membrane oxygenator appears to be the best therapy when the cardiac massage fails to restitute a normal myocardial function. No embolectomy was performed. The patient died when the bypass was stopped after 48 hours. We conclude that the prolonged peripheral extracorporeal bypass followed by embolectomy is the best therapy of pulmonary embolism.

[Selective external vein phlebography].

The authors describe a simple technique for opacification selectively of the external saphenous venous system. The principal features of the test are: direct puncture of the external saphenous system, and dynamic study of the Xray image. Selective phlebography of the external saphenous facilitates the choice between sclerosant and surgical treatment as well as the execution of the latter.

[External saphenectomy. Postero-lateral approach to the arch].

The authors describe a technique of external saphenectomy characterized by: 1) the position of the patient, in dorsal decubitus, so that an internal saphenectomy may be carried out at the same operation; 2) local anaesthesia; 3) postero-lateral approach to the arch of the external saphenous.
