The authors believe that operation should be performed early because children withstand thoracic surgical procedures so much better t,han do adults, because the operation is technically easier, and because the shorter the duration of patency the less the degree of pulmonary dilatation, cardiac enlargement, vessel sclerosis, and the less severe the postoperative reaction. Early intervention should be preceded by a period of observation during which diagnostic studies are made, and which is long enough to preclude the rarity of spontaneous closure,

ABSTRACTS

Patients are often urged to lead an inactive life during childhood, may be forced to inactivity by a diminished cardiac reserve in early adulthood, and throughout life are distinctly more susceptible to bacterial endocarditis, aneurysm and rupture of the ductus, or thrombus formation as well as rapid or slow cardiac failure. In some instances, middle life may be reached comfortably. Such instances are rather rare inasmuch as Abbott found the mean age of ninety-two patients to be 24 years at the time of death. On the other hand, the risk of operation is much greater in adults near the limit of their cardiac reserve. The operation may be most difficult because of sclerosis, or because the ductus finally becomes nothing but adjacent holes in the wall of two large vessels. Exploration should be undertaken most cautiously in later life, and in some instances the physician should abandon it rather than attempt to d’issect around something mhich has ceased to exist.

In all severe cases of Buerger’s disease and in selected cases of severe peripheral arteriosclerosis the operation of sympathectomy should be given serious consideration. If the preoperative tests result in a rise in skin temperature of 3” C. or more, a beneficial result from operation can be assured. Even a lower rise in skin temperature does not entirely preclude the possibility of improvement sufficiently great LO justify the procedure. AUTHOR.

Thrombophlebitis

Embolism.

The authors believe that the immediate decision to be made in any given case of thrombophlebitis is whether the patient should be treated conservatively or by ligation of the vein. If conservative therapy is employed, lumbar injection of procaine hydrochloride should be done if vasospasm is considerable. If the deep venous channels are interrupted, heparin is often of value when administered postIt must be emphasized that these concepts may be modified greatly operatively. as our experience increases. The important fact is that thrombophlebitis is no longer observed passively but is now accepted as a disease that must be treated vigorously. AUTHORS.
