Two heroes of the Class of Onety-Seven: Part II.

Frederick Banting and Norman Bethune were linked in time, place of birth, as classmates in medical college, veterans of World War I and heroes to different worlds. Both were surgeons, sharing the decisiveness that is characteristic of the profession. Both had their surgical ambitions frustrated. Banting, a failed orthopedist, was sidetracked to research; Bethune, a successful surgeon inactivated by tuberculosis, was directed by his interest in his disease to thoracic surgery. Frustrated in his battle for socialized medicine, Bethune went to war against the Fascists in Spain and the Imperialists in China. Banting discovered insulin, but did little else in original research. However, he organized research in Canadian universities which studied pilot safety in air warfare in World War II. The two heroes died within 2 years of each other, Bethune of an infection contracted at surgery on wounded Chinese soldiers and Banting in a plane crash while on a secret mission carrying his research results to Great Britain.

Canada↗

Evolution of the in situ bypass.

The origins of the in situ vein bypass in Montreal, Canada and in London, England, are described. The subsequent evolution of the original techniques in Europe and the United States are followed. The condemnation of the procedure in the United States in 1969 is noted. The persistence of Cartier in Montreal and Hall in Norway and the revival of interest in the procedure by Leather and Karmody in Albany, New York, is recounted. The pathophysiologic basis for the complications of the method are analyzed and the measures by which they are currently remedied are shown. The method's present superiority is reported. The initial rejection and slow acceptance of this method is explained in terms of the special conditions attendant on its introduction and the attitudes of surgeons to new procedures.

A new button for retention suture fixation.

A button that may be snapped on and off the end of a retention suture has been described. It allows the tension on the suture to be adjusted easily, increases patient comfort, and avoids circumferential compression of the wound.

Abdominal Muscles↗

Technique of varicose vein surgery.

A technique for varicose vein surgery is described which allows maximum removal of varicose veins and the trunks draining into them. Hemostasis by means of tantalum clips allows for distal ligation of branches beyond their bifurcations in sites of difficult access. This results in minimal blood loss and enables subdivision of collateral veins to prevent recurrence of varicosities.

Humans↗

A new method of preclotting fabric prostheses. A preliminary report.

A new method of preclotting arterial fabric prostheses is described. The preclotting process depends on infusion of blood into a polyethylene bag containing the prosthesis. Massage of the bag aids permeation of the graft, and a second infusion of blood over a 1 minute period seals the fraft completely. Rapid preclotting and asepsis are the unique features of this method.

Blood Coagulation↗

Diagnosis and management of arterial mural thromboemboli.

If ischemic lesions or cerebral dysfunction appear without obvious cause, aneurysm, stenosing, or ulcerative plaques in proximal arteries are suspected. Diagnostic methods are outlined. Treatment by removal of the embolic source is preferred and exclusion of the lesion and bypass is reserved for inacessible lesions or poor operative risks.

Skin closure using a new skin clip.

A new skin clip that allows rapid skin closure with minimal trauma to the skin has been devised. The clip can be used in most conventional incisions on the neck, extremities, thorax, and abdomen. It cannot be used where skin is tightly adherent, as in the scalp, palm, and soles of the feet. Closure with this skin clip has proved to be dependable and to provide an aesthetic hairline scar.
