Use of athrombogenic tubing for perfusion rewarming following surface-induced deep hypothermia.

A method of heparinless, oxygenatorless, left heart bypass perfusion rewarming following surface hypothermia, with the use of a closed circuit with 130 ml. prime volume including heat exchanger, has been devised. The use of polyurethane-polyvinyl-graphite (PPG)-coated tubing has previously been reported.

Gel foam embolization of a functioning pheochromocytoma.

For the first time, to our knowledge, a patient with a functioning pheochromocytoma was subjected to gel foam embolization for physiologic destruction of the tumor. The operation, 24 hours later, provided an uneventful anatomic removal of the infarcted tumor. Observation was considered as a possible alternative to surgical excision.

Prefabricated Dacron baffle for use in correction of transposition of the great arteries.

Interatrial venous transposition for correction of transposition of the great arteries (TGA) is facilitated by using a premolded Dacron baffle. Fine-mesh Dacron is easily fashioned to the desired shape in a metallic brass mold at 200 degrees C. The resultant baffle material can be autoclaved without losing its shape or altering the fabric characteristics of flexibility and porosity.

Current practice of coronary artery bypass surgery. Results of a national survey.

A survey of techniques used in coronary artery bypass graft (CABG) surgery by 400 experienced cardiac surgeons is presented. These surgeons performed 41,000 CABG operations in 1975. A seventy-question survey form was answered by each surgeon on their techniques for cardiopulmonary bypass and myocardial preservation, choice of bypass conduit, and grafting techniques.
