All sacular and all significant fusiform abdominal aneurysms should be excised. Aneurysms of the ascending aorta should also be excised when they are associated with aortic valvular insufficiency or are secondary to a coaretation. Dissecting aortic aneurysms should be treated under hypotension if possible, and an operation should only be performed in the(More)
1. 100 elective operations on the aorto-iliac arteries (13 endarterectomies, 87 artificial bypaβ-procedures) were followed by 12 severeearly complications in 8 patients with two deaths. 2. During an average follow-up time of 36,5 month, 30 additional patients showed severelate complications. 3. Aneurysm (11 cases) andInfection (4 cases) were seen rather(More)
For correction of a short single stenosis in the right coronary artery, patch graft is considered to be a good technique. 13 operations were made with one operative and one late deaths 5 years after operation. The Vineberg mammaria interna implantation in the myocardium increases the coronary flow only after months and it is difficult to exclude that the(More)
Certain cases of maβive pulmonary embolism have such a rapid course that no time is left for operation in extracorporeal circulation, and that even the claβical Trendelenburg operation is not succeβful because of lack of time or exceβive cardiac streβ. This is especially valid for patients where heart arrest has already occured. In such extreme emergencies(More)
Reoperation of the aortic valve was performed in 103 patients; in 12 % a previous reconstruction of the valve was performed (interval 6.5 years), in 12 % a valve replacement (interval 2.2 years), and in 76 %, a fascia lata plastic (interval 5.7 years). Early mortality was about 4 % higher than that of the primary operation (3.7 % in the same period). The(More)
The postoperative lethality (30 days) after radical pneumonectomy (n=21) with intrapericardial disconnection of the vessels, partial pericardectomy or atrial resection (group A) is 19%, after extended thoracic wall and lung resection (n=8) 11% (group B), after radical ipsilateral lymph node and lung resection (n=12) 23% (group C), and after bronchoplastic(More)
Porcine tissue valves implanted in dogs and in humans show similar SEM surface changes. Immediately after implantation (30 s) the leaflets of the prostheses are covered with a protein layer that is followed by the deposition of fine fibrinous fibers (1 min). Later (2–3 min) white blood cells and platelets as well as macrophages and microthrombi stick on the(More)
