[Problems of general surgery in the cardiosurgical patient].

The preoperative problem is analysed with proposal of a heart risk index table and assessment of the manifold problems involved. Stress is thenn laid on the importance of careful postoperative treatment, establishing rules of surgical and resuscitatory behaviour to be followed in the general surgery of the heart patient. These rules of behaviour permit prevention of surgical complications, which are fully illustrated. Particular attention is paid to the selection of those conditions of pertinence to general surgery which have treatment of choice prior to heart surgery. Personal experience of 75 general surgery operations between 1977 and 1979 in the Villa Pia Clinic is then reviewed.

[Malignant hyperthermia treated with refrigerant venous catheterization].

A cold water circulation heat exchanger metal probe was used in 3 patients to treat severe hyperthermia. The probe was introduced into the caval veins by way of the sephenous vein. In 40' temperature fell from 42 degrees to 37 degrees and the patients were saved. The apparatus is simple and the technique straightforward.

[Akinetic zones of the left ventricle in aortic insufficiency. Treatment].

22 cases of aortic valvular insufficiency treated by prosthesis and in which the acinetic areas of the left ventricle were eliminated at the same time are reported. Only one postoperative death (ventricular fibrillation) was encountered; one after 1 year (emboly as a result of endocarditis) and one as a result of an unknown cause. Emphasis is laid upon the frequency of this associated complication, its seriously negative incidence on ventricular haemodynamics, the need for surgical treatment, and its favourable immediate and long-term results.

Aortic Valve Insufficiency↗

[Plastic widening of the aorta associated with implantation of valvular prosthesis].

Widening of the supravalvular aorta by means of a lozenge-shaped dacron patch was performed in 9 cases of stenosis and/or aorta insufficiency. Marked improvement was noted in the 8 patients followed up: the transvalvular gradient was not significant and neither haemolytic anaemia nor hyperhaemolysis were present. This expedient is both useful and indicated in cases where the calibre of the descending aorta is small.
